I'm trying to write a wpf with webrtc support. The access to the camera works but the display of the <video> from the page doesn't. Can anyone help?
You can do something like this:
var cefSettings = new CefSettings();
cefSettings.CefCommandLineArgs.Add("enable-media-stream", "enable-media-stream");
Cef.Initialize(cefSettings);
This has the same effect as passing the command line argument
I assume you want to display video from your camera via WebRTC so I think it requires a call to .getUserMedia() to get hold of your camera. For that to work you must use CefSharp based on Chromium 30 or later. So either:
Use the latest CefSharp.Wpf NuGet. Right now you need latest -Pre release
or build from source with the current master branch.
I just did a quick test again using CefSharp.MinimalExample so here are the steps:
Make sure your MinimalExample uses Chromium 31 or higher - see this PR - unless it already got merged by the time you are reading this.
In MainView.xaml modify the <cefSharp:WebView Address= /> attribute to "https://simpl.info/getusermedia/sources/index.html"
Build and when running add the --enable-media-stream command line flag.
That's it! With your camera connected and a bit of luck you should see your own face - or whatever the camera points to - on the screen.
Bonus info: Hopefully soon PR #365 can get a bit of extra love to allow for passing flags too and get merged into CefSharp. With that you can set the flag in code instead of having to pass it in as a command line parameter.
The correct code is this
Dim settings As New CefSettings settings.CefCommandLineArgs.Add("--enable-media-stream", "1") CefSharp.Cef.Initialize(settings) settings.CachePath = "cache"

When opening my ios app via an applink, as specified by associated domains feature, the AppArg is null.
The consecutive call of start() method, as described in this issue, does not occur.
In my case, start() is called only once, with a null AppArg, and that's it.
The first thing a do, in the start() method, is call
Display.getInstance().getProperty("AppArg",null);
This works fine when opening the app via a custom scheme, but not when opening via an applink.
Note: I use the ios.glAppDelegateBody and ios.afterFinishLaunching build hints to handle app open via push notification. I figured this might interfere with AppArg reading so I removed those temporarily and tried again, but to no avail.
Currently, the only solution I see is to write some native code and try to get the opening url this way, but I'd very much like for the AppArg to work as it states.
I've tested on iphone 6s with ios 15.1.
Update 3:
This problem occurs due to the call of the facebook sdk in the didFinishLaunchingWithOptions which causes the method to return NO, and that prevents continueUserActivity to execute and retrieve the launch url. The offending code is this:
return [[FBSDKApplicationDelegate sharedInstance] application:application
didFinishLaunchingWithOptions:launchOptions];
This code gets executed if the facebook.appIdbuild hint is present in the codenameone settings.
After I removed it, things started working.
However, you won't be able to do this if you actually use facebook connect.
Update 2
I added the following snippet to the apple-app-site-association file hosted on my domain, as per the documentation here.
"activitycontinuation": {
"apps": [ <id of my app> ]
}
It didn't work still.
The same documentation also states the an associated domain entitlement like this: activitycontinuation:example.com should be added. So I added it to the ios.associatedDomains build hint, along with the applinks, looking like this:
ios.associatedDomains=applinks:mydomain.com,activitycontinuation:mydomain.com
It still didn't work. The build suceeded, but I'm not sure that codename one is actually doing something with activitycontinuation service.
So, the problem is still not solved!
Update:
So, the flow start,stop,start only happens when the app is in background and gets opened via an applink click, and both times start is called with the AppArg populated with the applink. All well in this case.
However, if the app is closed, and opepend via applink click, start is called only once and the AppArg is null. Problem!
The method shouldApplicationHandleURL is never called. I implemented it on the main app class, returning true.
I have also tried adding native code to try to get the applink, for the case when the app was previously closed. I tried to add the code below to the glAppDelegateBody build hint, but the build failed complaining that the continueUserActivity is duplicate. The code used was something like this:
- (BOOL)application:(UIApplication *)application
continueUserActivity:(NSUserActivity *)userActivity
restorationHandler:(void (^)(NSArray *restorableObjects))restorationHandler {
NSURL *url = userActivity.webpageURL;
// Handle url
return YES;
}
Currently, I'm running out of ideas. So, please, help. Thank you.
iOS uses a different mechanism for dealing with applinks than it does for custom app URL schemes, so it is likely that there is a race condition here -where start() is being called before the URL is provided to the app.
Try implementing the com.codename1.system.URLCallback interface in your main lifecycle class and implement the shouldApplicationHandleURL method. This should be called when an applink is processed.
The solution, in my case, was to remove the facebook.appId build hint from the condenameone_settings.properties. I wasn't using facebook anymore, but forgot about the build hint. After removing it, things started working.
Found about this here.
By adding the following code to the ios.afterFinishLaunching build hint, the AppArg will be populated at start with the app launchUrl (if any), regardless of the fact that facebook sdk is used or not:
NSDictionary *activityDictionary = [launchOptions objectForKey:UIApplicationLaunchOptionsUserActivityDictionaryKey];
if (activityDictionary) {
NSUserActivity *userActivity = [activityDictionary valueForKey:#"UIApplicationLaunchOptionsUserActivityKey"];
if (userActivity != nil) {
if ([NSUserActivityTypeBrowsingWeb isEqualToString:userActivity.activityType] && userActivity.webpageURL != nil) {
JAVA_OBJECT launchUrlStr = fromNSString(CN1_THREAD_GET_STATE_PASS_ARG [userActivity.webpageURL absoluteString]);
JAVA_OBJECT appArgKey = fromNSString(CN1_THREAD_GET_STATE_PASS_ARG #"AppArg");
JAVA_OBJECT displayInstObj = com_codename1_ui_Display_getInstance__(CN1_THREAD_GET_STATE_PASS_SINGLE_ARG);
com_codename1_ui_Display_setProperty___java_lang_String_java_lang_String(CN1_THREAD_GET_STATE_PASS_ARG displayInstObj, appArgKey, launchUrlStr);
}
}
}
In short:
I'm new to VisualStudio Extensibility and my goal is to create an extension with a ToolWindow (which already works) showing different views for each context of a VisualStudio solution, i. e. a view for the solution, a view for a project etc.. The window should be opened by clicking on a context menu entry in the context menus of the Solution Explorer, Class View, Object Browser and (ideally) any other window showing contents like projects, namespaces, classes etc..
After searching I found a lot of information, but for some points I couldn't find very helpful information. How do I ...
... create a context menu item for the VisualStudio views?
... get the currently open solution as an instance in code?
... get the projects of the solution and their contens as instances in code?
... add/remove items to/from a solution/project/class/... in code?
... react to selection changes in the Solution Explorer?
What I've done, so far:
I read the docs for Starting to Develop Visual Studio Extensions and downloaded the VSSDK-Extensibility-Samples. Especially the WPF_Toolwindow example was interesting for my purposes, so I built and ran it, which was successful, so far. Another interesting sample would have been the WPFDesigner_XML, but it always throws a NullReferenceException, so I decided to stick with the former ToolWindow, which is completely fine, for now.
Furtermore, I tried to understand the example by having a close look at each file in the project, running it in the debugger and analyzing what happened. I'm confident I understood it, but am also open for corrections of my possibly misguided thoughts following.
Now, I have created a new project, based on the WPF_Toolwindow sample, renamed and adapted to my needs (basically, I created new GUIDs, renamed the namespaces and removed things I won't use). This extension still works in the debugger. I even uninstalled everything from the experimental instance and debugged the extension from scratch.
What I try to achieve:
Have the ToolWindow load a specific view/viewmodel, when the selection changes in the Solution Explorer (or any other VisualStudio view). Alternatively, there should be a context menu item for every node's context menu in the Solution Explorer tree (or any other VisualStudio view).
Get the currently open solution, the containing projects and basically everything from the Solution Explorer's content as instances processable in my viewmodel. I need to properly add/remove
classes/structs/enums to/from
a folder in a project
a namespace
properties/fields to/from a class/struct
Generate code based on information of the solution and add the file properly to a project.
Does anyone know of examples for something like this or can anyone give me some hints, where I can find further information? Any help would be appreciated. Thanks in advance.
(1) The items already have a context menu and I want to add a new command to this menu.
if you want to add a sub menu to the context menu, the following link provide a complete sample
https://github.com/visualstudioextensibility/VSX-Samples/tree/master/CommandSubmenu
(3) Yes, basically adding a file to a project without manually manipulating the project file would be nice.
You can add the file to project via Project.ProjectItems.AddFromFile, and the following provide a sample for your reference.
https://www.mztools.com/Articles/2014/MZ2014009.aspx
Update:
I select a project and a similar event is fired. Are there such events I can subscribe to?
You could use IVsMonitorSelection to implement. here is the code which retrieve related project path for your reference.
IntPtr hierarchyPointer, selectionContainerPointer;
Object selectedObject = null;
IVsMultiItemSelect multiItemSelect;
uint projectItemId;
IVsMonitorSelection monitorSelection =
(IVsMonitorSelection)Package.GetGlobalService(
typeof(SVsShellMonitorSelection));
monitorSelection.GetCurrentSelection(out hierarchyPointer,
out projectItemId,
out multiItemSelect,
out selectionContainerPointer);
IVsHierarchy selectedHierarchy = Marshal.GetTypedObjectForIUnknown(
hierarchyPointer,
typeof(IVsHierarchy)) as IVsHierarchy;
if (selectedHierarchy != null)
{
ErrorHandler.ThrowOnFailure(selectedHierarchy.GetProperty(
projectItemId,
(int)__VSHPROPID.VSHPROPID_ExtObject,
out selectedObject));
}
Project selectedProject = selectedObject as Project;
string projectPath = selectedProject.FullName;

I am using Appium 1.6 to automate Android UI Tests.
In this image, I am unable to select any country (ex: Japan) from the spinner.
This is the code I am using:
driver.findElement(By.id("com.akkipet.android:id/country_spinner__add_information")).click();
driver.findElement(MobileBy.AndroidUIAutomator("new UiScrollable(new UiSelector()).scrollIntoView("+ "new UiSelector().text(\"India\"));")).click()
What am I doing wrong? After clicking on the spinner, though I'm not able to read the country values, I can read other fields like First Name, Last Name etc.
For now, I am using the tap functionality to tap at the specific coordinates to choose the required option. But this will make it device specific. Further, since the options list varies depending on the environment, I will have to give a different set of coordinates for each environment.
Code for Tap:
touchAction.tap (200, 850).perform();
Could anyone suggest a better workaround?
Try this one. It worked for me.
driver.findElement(By.id("com.akkipet.android:id/country_spinner__add_information")).click();
driver.findElement(By.name("India")).click();
By.Name has been deprecated. Try using findElementByAndroidUIAutomator.
Eg:
driver.findElementByAndroidUIAutomator("new UiSelector().text("India")").click();
I read this post where someone asked
How can I change flash player version in flash cs6? and there was an answer instructing him how to add Flash Player 15, so I figured I could do something similar with Flash Player 23, but it doesn't seem to be working properly. Does Adobe not provide a FlashPlayer23_0.xml file themselves? There are lots of lines in there, and copying one of the older xml files and editing a couple of them as the guide suggests doesn't seem right. In one of the lines I'm supposed to edit, I'm not sure what to put in for the version of FlashPlayer23.0.
<player id="FlashPlayer23.0" version="XX" asversion="3">
After doing all that, in Flash Pro I now see a "Flash Player 23" in the Target dropdown of the Publish section, and I have that selected, but when I actually publish, I get an error when I try to use one of the newer Flash features.
I'm actually just trying to use the new removeAt() Array method where you can remove one element of an array by its index. It says you need at least Flash Player 19 for it to work. Here is my test code:
var a:Array = [0,1,2];
a.removeAt(1);
trace(a);
If I try that out with Flash Player 11 as the publish setting, I get the following expected error:
TypeError: Error #1006: removeAt is not a function.
If I set it to publish to Flash Player 23, I get this error:
ReferenceError: Error #1069: Property http://adobe.com/AS3/2006/builtin::removeAt not found on Array and there is no default value.
Does anyone know why this is?
(1)
In one of the lines I'm supposed to edit, I'm not sure what to put in
for the version of FlashPlayer 23.0.
Always look for something called "release notes" for your version and it will tell you the number. The FlashPlayer 23.0 release notes (see Authoring Guidelines section) say :
To use the new Flash Player, you will need to target SWF version 34 by
passing "-swf-version=34"...
Set that as : <player id="FlashPlayer23.0" version="34" asversion="3">
(2)
I get an error when I try to use one of the newer Flash features
Did you actually replace the existing older playerglobal.swc file with the newest downloaded one (for FP 23.0 features)? The compiler needs the latest Flash Player file placed in the installation folders.
Remember installing the plugin from Adobe website is just for benefit of browsers, you still need to manually setup the installed Flash CC or CS software with the latest SWC file so that the compiler understands these new commands/features.
Im trying to use Microsoft.Office.Interop.Word._Document.Close() in a .net 3.5 windows form app.
No matter how much I search here and on Google I cannot find the correct parameters to put in the Close method.
I am using version 14.0.0.0 of Microsoft.Office.Interop.Word and I would like to close the document without saving and ideally ensure that the application can isolate the document thread so that users can still open word documents outside the running application.
See the Close method of the Document class described in MSDN. If you need to omit the parameter and use the default value - pass the Type.Missing parameter.
Try this:
object doNotSaveChanges = Word.WdSaveOptions.wdDoNotSaveChanges;
object missing = System.Reflection.Missing.Value;
_Document.Close(ref doNotSaveChanges, ref missing, ref missing);
This is the source
I'm not sure if you'll need the middle line or not. It's not from the original source it's from here
