I have a very strange problem on my wpf application.
I use a webbrowser control to display a third-party web page that uses flash to provide some functionality.
On internet explorer 9 and 10 i have a particular behaviour : the first time I open the webbrowser control everything works fine, and the application puts a .SWF file inside my temporary internet files folder. When I close and reopen the webcontrol, the following error arise :
"object does not support property or method 'UpdateTimeLeft'".
If i manually delete the .SWF file inside the temporary folder, close ad reopen the application, everything works fine again.
This is the code that arise the exception :
var swfUrl = "//" + serverName + "/js/tv/FlashTurboLotto3.swf";
var expressSwfUrl = "//" + serverName + "/js/tv/expressInstall.swf";
var flashvars = {};
var params = {wmode:"transparent", allowscriptaccess:"always" };
var attributes = {id:"FlashTurboLotto3", name:"FlashTurboLotto3", align:"top"};
swfobject.embedSWF(
swfUrl,
"flashcontent",
"100%",
"197",
"9.0.0",
expressSwfUrl,
flashvars,
params,
attributes
);
function updateTimeleft(drawID, timeleft)
{
var swf = document.getElementById("FlashTurboLotto3");
swf.updateTimeleft(parseInt(drawID), timeleft);
}
does anyone have an idea of why this appens and how to solve the issue?
Thank in advance.
I found the solution - It is a very particular bug of Flash. Sometimes happens that when the flash application runs in a non-native browser (like, in my case, a webbrowser control in WPF) the javascript fails at retrieving the .swf file from the cache, so the Flash object will not get initialized.
I solved, for now, by forcing to not use the browser cache, simply adding a random value to the .Swf download Url.

I have been trying to capture Screenshots for Passed/Failed test in my testNG reports captured in Test-Output folder. I have succeeded in doing so, however I want a bit more improvement in the way things are right now.
The Screenshot is displayed in full size and covers the whole screen, I would like to make it appear smaller in report and then user can click on it to see the image maximized.
I am capturing the Screenshot with the help of Reporter.log(ScreenshotPath) in the static TakeScreenshot method which is a part of finally block in my test case.
public static void TakeScreenshotMethod() throws IOException {
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
File ScreenshotName = new File(UtilityClass.ScreenshotPathCustomerPortal + count +".jpg");
FileUtils.copyFile(scrFile, ScreenshotName);
String filePath = ScreenshotName.toString();
String path = "<img src=\"file://" + filePath + "\" alt=\"\"/>";
Reporter.log(path);
count++;
}
I would like to control the size of the image being displayed in my report.
You can a bit modify the <img> tag by adding a style like normal html with some property (width, height), like this:
String path = "<img src=\"file://" + filePath + "\" alt=\"\" style=\"width: 230px; height :500px;\" />";
If you are asking for this behavior in the default TestNG reports, then the answer is NO its not possible. TestNG reports are agnostic to the content that gets embedded in them. So TestNG doesn't know if an image or if a video for that matter is being embedded in it. So it also doesn't different on how to get them rendered.
If you would like to control these behaviors, you should do one of the following:
Build your own custom reporter that has this behavior by implementing the org.testng.IReporter interface and then wiring in this listener via the <listeners> tag or via #Listeners interface or via a Service Provider Interface mechanism. You can learn about wiring in listeners in general from my blog post here.
You can explore some of the reporting solutions that exist already out there such as allure reports (or) extent reports etc., and see if one of them fits your requirement and use them instead.
TestNG doesn't have any role to play in this.
Using .NET WPF and Windows 10, is there a way to push a local toast notification onto the action center using c#? I've only seen people making custom dialogs for that but there must be a way to do it through the os.
You can use a NotifyIcon from System.Windows.Forms namespace like this:
class Test
{
private readonly NotifyIcon _notifyIcon;
public Test()
{
_notifyIcon = new NotifyIcon();
// Extracts your app's icon and uses it as notify icon
_notifyIcon.Icon = Icon.ExtractAssociatedIcon(Assembly.GetExecutingAssembly().Location);
// Hides the icon when the notification is closed
_notifyIcon.BalloonTipClosed += (s, e) => _notifyIcon.Visible = false;
}
public void ShowNotification()
{
_notifyIcon.Visible = true;
// Shows a notification with specified message and title
_notifyIcon.ShowBalloonTip(3000, "Title", "Message", ToolTipIcon.Info);
}
}
This should work since .NET Framework 1.1. Refer to this MSDN page for parameters of ShowBalloonTip.
As I found out, the first parameter of ShowBalloonTip (in my example that would be 3000 milliseconds) is generously ignored. Comments are appreciated ;)
I know this is an old post but I thought this might help someone that stumbles on this as I did when attempting to get Toast Notifications to work on Win 10.
This seems to be good outline to follow -
Send a local toast notification from desktop C# apps
I used that link along with this great blog post- Pop a Toast Notification in WPF using Win 10 APIs
to get my WPF app working on Win10. This is a much better solution vs the "old school" notify icon because you can add buttons to complete specific actions within your toasts even after the notification has entered the action center.
Note- the first link mentions "If you are using WiX" but it's really a requirement. You must create and install your Wix setup project before you Toasts will work. As the appUserModelId for your app needs to be registered first. The second link does not mention this unless you read my comments within it.
TIP- Once your app is installed you can verify the AppUserModelId by running this command on the run line shell:appsfolder . Make sure you are in the details view, next click View , Choose Details and ensure AppUserModeId is checked. Compare your AppUserModelId against other installed apps.
Here's a snipit of code that I used. One thing two note here, I did not install the "Notifications library" mentioned in step 7 of the first link because I prefer to use the raw XML.
private const String APP_ID = "YourCompanyName.YourAppName";
public static void CreateToast()
{
XmlDocument toastXml = ToastNotificationManager.GetTemplateContent(
ToastTemplateType.ToastImageAndText02);
// Fill in the text elements
XmlNodeList stringElements = toastXml.GetElementsByTagName("text");
stringElements[0].AppendChild(toastXml.CreateTextNode("This is my title!!!!!!!!!!"));
stringElements[1].AppendChild(toastXml.CreateTextNode("This is my message!!!!!!!!!!!!"));
// Specify the absolute path to an image
string filePath = Environment.GetFolderPath(Environment.SpecialFolder.ProgramFilesX86) + #"\Your Path To File\Your Image Name.png";
XmlNodeList imageElements = toastXml.GetElementsByTagName("image");
imageElements[0].Attributes.GetNamedItem("src").NodeValue = filePath;
// Change default audio if desired - ref - https://learn.microsoft.com/en-us/uwp/schemas/tiles/toastschema/element-audio
XmlElement audio = toastXml.CreateElement("audio");
//audio.SetAttribute("src", "ms-winsoundevent:Notification.Reminder");
//audio.SetAttribute("src", "ms-winsoundevent:Notification.IM");
//audio.SetAttribute("src", "ms-winsoundevent:Notification.Mail"); // sounds like default
//audio.SetAttribute("src", "ms-winsoundevent:Notification.Looping.Call7");
audio.SetAttribute("src", "ms-winsoundevent:Notification.Looping.Call2");
//audio.SetAttribute("loop", "false");
// Add the audio element
toastXml.DocumentElement.AppendChild(audio);
XmlElement actions = toastXml.CreateElement("actions");
toastXml.DocumentElement.AppendChild(actions);
// Create a simple button to display on the toast
XmlElement action = toastXml.CreateElement("action");
actions.AppendChild(action);
action.SetAttribute("content", "Show details");
action.SetAttribute("arguments", "viewdetails");
// Create the toast
ToastNotification toast = new ToastNotification(toastXml);
// Show the toast. Be sure to specify the AppUserModelId
// on your application's shortcut!
ToastNotificationManager.CreateToastNotifier(APP_ID).Show(toast);
}
UPDATE
This seems to be working fine on windows 10
https://msdn.microsoft.com/library/windows/apps/windows.ui.notifications.toastnotificationmanager.aspx
you will need to add these nugets
Install-Package WindowsAPICodePack-Core
Install-Package WindowsAPICodePack-Shell
Add reference to:
C:\Program Files (x86)\Windows Kits\8.1\References\CommonConfiguration\Neutral\Windows.winmd
And
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETCore\v4.5\System.Runtime.WindowsRuntime.dll
And use the following code:
XmlDocument toastXml = ToastNotificationManager.GetTemplateContent(ToastTemplateType.ToastImageAndText04);
// Fill in the text elements
XmlNodeList stringElements = toastXml.GetElementsByTagName("text");
for (int i = 0; i < stringElements.Length; i++)
{
stringElements[i].AppendChild(toastXml.CreateTextNode("Line " + i));
}
// Specify the absolute path to an image
string imagePath = "file:///" + Path.GetFullPath("toastImageAndText.png");
XmlNodeList imageElements = toastXml.GetElementsByTagName("image");
ToastNotification toast = new ToastNotification(toastXml);
ToastNotificationManager.CreateToastNotifier("Toast Sample").Show(toast);

I managed to gain access to the working API for windows 8 and 10 by referencing
Windows.winmd:
C:\Program Files (x86)\Windows Kits\8.0\References\CommonConfiguration\Neutral
This exposes Windows.UI.Notifications.
You can have a look at this post for creating a COM server that is needed in order to have notifications persisted in the AC with Win32 apps https://blogs.msdn.microsoft.com/tiles_and_toasts/2015/10/16/quickstart-handling-toast-activations-from-win32-apps-in-windows-10/.

I have the Chromium source on Windows 7, and launch my custom app with the --app="..url" switch through a .bat file. How can I prevent users from opening more than one instance of my Chromium app? This includes opening the .exe directly, using the .bat file and by selecting "Chromium" from the jump list menu on the task bar.
If the app is launched with the --app="...url" flag, then the following solution will prevent further "instances" of Chrome being opened. I say "instances" because Chrome doesn't actually create new Chrome base processes. Instead, it opens a new window with a process used for rendering that particular window.
So, when the app is in --app mode, all you need to do is prevent new windows from opening. This can be accomplished by modifying the OpenApplicationWindow() method within the Chromium source code Application_launch class: chrome/browser/ui/extensions/application_launch.cc.
...
OpenApplicationWindow(const AppLaunchParams& params) {
browser = chrome::FindBrowserWithProfile(profile, params.desktop_type);
#endif
WebContents* web_contents;
if (!browser) {
browser = new Browser(browser_params);
web_contents = chrome::AddSelectedTabWithURL(
browser, url, content::PAGE_TRANSITION_AUTO_TOPLEVEL);
web_contents->GetMutableRendererPrefs()->can_accept_load_drops = false;
web_contents->GetRenderViewHost()->SyncRendererPrefs();
}
else {
web_contents = browser->tab_strip_model()->GetActiveWebContents();
}
browser->window()->Show();
...
*NOTE: There should be some Windows 8 code in this method already. The idea is to remove the conditions for Windows 8 Metro Mode, so new Windows are always prevented.
I have the following requirement for a business application:
(All of this could be on local or server)
Allow user to select folder location
Show contents of folder
Print selected items from folder (*.pdf)
Display which files have been printed
Potentially move printed files to new location (sub-folder of printed)
How can I make this happen in Silverlight?
Kind regards,
ribald
First of all, all but the last item can be done (the way you expect). Due to security protocols, silverlight cannot access the user's drive and manipulate it. The closest you can get is accessing silverlight's application storage which will be of no help to you whatsoever in this case. I will highlight how to do the first 4 items.
Allow user to select folder location & Show contents of folder
public void OnSelectPDF(object sender)
{
//create the open file dialog
OpenFileDialog ofg = new OpenFileDialog();
//filter to show only pdf files
ofg.Filter = "PDF Files|*.pdf";
ofg.ShowDialog();
byte[] _import_file = new byte[0];
//once a file is selected proceed
if (!object.ReferenceEquals(ofg.File, null))
{
try
{
fs = ofg.File.OpenRead();
_import_file = new byte[fs.Length];
fs.Read(_import_file, 0, (int)fs.Length);
}
catch (Exception ex)
{
}
finally
{
if (!object.ReferenceEquals(fs, null))
fs.Close();
}
//do stuff with file - such as upload the file to the server
};
}
If you noticed, in my example, once the file is retrieved, i suggest uploading it to a webserver or somewhere with temporary public access. I would recommend doing this via a web service. E.g
//configure the system file (customn class)
TSystemFile objFile = new TNetworkFile().Initialize();
//get the file description from the Open File Dialog (ofg)
objFile.Description = ofg.File.Extension.Contains(".") ? ofg.File.Extension : "." + ofg.File.Extension;
objFile.FileData = _import_file;
objFile.FileName = ofg.File.Name;
//upload the file
MasterService.ToolingInterface.UploadTemporaryFileAsync(objFile);
Once this file is uploaded, on the async result, most likely returning the temporary file name and upload location, I would foward the call to some javascript method in the browser for it to use the generic "download.aspx?fileName=givenFileName" technique to force a download on the users system which would take care of both saving to a new location and printing. Which is what your are seeking.
Example of the javascript technique (remember to include System.Windows.Browser):
public void OnInvokeDownload(string _destination)
{
//call the browser method/jquery method
//(I use constants to centralize the names of the respective browser methods)
try
{
HtmlWindow window = HtmlPage.Window;
//where BM_INVOKE_DOWNLOAD is something like "invokeDownload"
window.Invoke(Constants.TBrowserMethods.BM_INVOKE_DOWNLOAD, new object[] { _destination});
}
catch (Exception ex) { System.Diagnostics.Debug.WriteLine(ex.ToString()); }
}
Ensure you have the javascript method existing either in an included javaScript file or in the same hosting page as your silverlight app. E.g:
function invokeDownload(_destination) {
//some fancy jquery or just the traditional document.location change here
//open a popup window to http://www.myurl.com/downloads/download.aspx? fileName=_destination
}
The code for download.aspx is outside the scope of my answer, as it varies per need and would just lengthen this post (A LOT MORE). But from what I've given, it will "work" for what you're looking for, but maybe not in exactly the way you expected. However, remember that this is primarily due to silverlight restrictions. What this approach does is rather than forcing you to need a pluging to view pdf files in your app, it allows the user computer to play it's part by using the existing adobe pdf reader. In silverlight, most printing, at least to my knowledge is done my using what you call and "ImageVisual" which is a UIElement. To print a pdf directly from silverlight, you need to either be viewing that PDF in a silverlight control, or ask a web service to render the PDF as an image and then place that image in a control. Only then could you print directly. I presented this approach as a lot more clean and direct approach.
One note - with the temp directory, i would recommend doing a clean up by some timespan of the files on the server side everytime a file is being added. Saves you the work of running some task periodically to check the folder and remove old files. ;)
Should the loading of OnDemand Prism modules work in an OOB scenerio? If so, I cannot seem to make it work. Everything is currently working in browser without any problems. Specifically I:
register my modules in code:
protected override IModuleCatalog GetModuleCatalog() {
var catalog = new ModuleCatalog();
Uri source;
if( Application.Current.IsRunningOutOfBrowser ) {
source = IsolatedStorageSettings.ApplicationSettings[SOURCEURI] as Uri;
}
else {
var src = Application.Current.Host.Source.ToString();
src = src.Substring( 0, src.LastIndexOf( '/' ) + 1 );
source = new Uri( src );
IsolatedStorageSettings.ApplicationSettings[SOURCEURI] = source;
IsolatedStorageSettings.ApplicationSettings.Save();
}
if( source != null ) {
var mod2 = new ModuleInfo { InitializationMode = InitializationMode.OnDemand,
ModuleName = ModuleNames.mod2,
ModuleType = "mod2.Module, mod2.Directory, '1.0.0.0', Culture=neutral, PublicKeyToken=null" ),
Ref = ( new Uri( source, "mod2.xap" )).AbsoluteUri };
catalog.AddModule( mod2 );
}
// per Jeremy Likeness - did not help.
Application.Current.RootVisual = new Grid();
return ( catalog );
}
later request for the module to be loaded is made:
mModuleManager.LoadModule( ModuleNames.mod2 );
and wait for a response to an event published during the initialization of that loaded module.
The module appears to never be loaded, and when the application is running under the debugger there will be a message box that states that the web server returned a 'not found' error. I can take the requesting url for the module and enter it into Firefox and download the module with no problem.
I have not been able to find any reference to this actually being workable, but it seems as though it should. The most I have found on the subject is a blog entry by Jeremy Likeness, which covers loading modules in MEF, but applying his knowledge here did not help.
The server is localhost (I have heard it mentioned that this might cause problems). The server has a clientaccesspolicy.xml file - although I don't expect that is needed.
I am using the client stack and register it during app construction:
WebRequest.RegisterPrefix( Current.Host.Source.GetComponents( UriComponents.SchemeAndServer, UriFormat.UriEscaped ), WebRequestCreator.ClientHttp );
Followup questions:
Can all of the xaps be installed to the client desktop in some manner - or only the main application xap? specify them in appmanifest.xml somehow??
Is it worth it make this work if only the application.xap is installed and the rest of the xaps must be downloaded anyway?
Once I worked on a similar scenario. The trick is having the modules stored in isolated storage and use a module loader that reads from isolated storage when working offline.
This is because otherwise, you can't get download the modules that are in a different .xap file than the Shell.
Thanks,
Damian
It is possible to hook custom module loaders into Prism if you're willing to tweak the Prism source and build it yourself. I was actually able to get this to work pretty easily - in our app, I look on disk first for the module, and if it's not found, I fall back to loading it from the server via a third-party commercial HTTP stack that supports client certificates.
To do this, download the Prism source code, and locate the Microsoft.Practices.Composite.Modularity.XapModuleTypeLoader class. This class uses another Prism class, Microsoft.Practices.Composite.Modularity.FileDownloader, to download the .xap content; but it instantiates it directly, giving you no chance to inject your own or whatever.
So - in XapModuleTypeLoader, I added a static property to set the type of the downloader:
public static Type DownloaderType { get; set; }
Then I modified the CreateDownloader() method to use the type specified above in preference to the default one:
protected virtual IFileDownloader CreateDownloader() {
if (_downloader == null) {
if (DownloaderType == null) {
_downloader = new FileDownloader();
} else {
_downloader = (IFileDownloader)Activator.CreateInstance(DownloaderType);
}
}
return _downloader;
}
When my app starts up, I set the property to my own downloader type:
XapModuleTypeLoader.DownloaderType = typeof(LocalFileDownloader);
Voila - now Prism calls your code to load its modules.
I can send you my LocalFileDownloader class as well as the class it falls back to to load the .xap from the web if you're interested... I suspect though that if you look at Prism's FileDownloader class you'll see that it's simple enough.
With regard to your other questions, the clientaccesspolicy.xml file is probably not needed if the URL the app is installed under is the same one you're talking to, or if you're in elevated trust.
The .xaps can definitely be pre-installed on the client, but it's a bit of work. What we did was write a launcher app that is a standalone .NET 2.0 desktop app. It downloads the main .xap plus certain modules* (checking for updates and downloading only as needed), then uninstalls/reinstalls the app if necessary, then launches the app. The last two are done via sllauncher.exe, which is installed as part of Silverlight. Here's a good intro to that: http://timheuer.com/blog/archive/2010/03/25/using-sllauncher-for-silent-install-silverlight-application.aspx.
Assuming you're running under elevated trust, it should also be possible to pre-fetch the module .xaps from within the SL client, but before they're actually requested due to user action. You'd just need to put them in a folder under My Documents somewhere, and then use the custom module loading approach described above to pull them from there.
*In our case, our main .xap is 2/3 of the application. The rest of our .xaps are small, so we download them on-the-fly, with the exception of some .xaps we created as containers for third-party components. We don't expect to update those very often, so we pre-install them.
