I made a WPF application for family business which was working fine earlier. Last month they formatted the PC and this time installed XP. While the application still works, but it crashes as soon as an invoice or any other print action is taken.
Following is the code. Let me know any workaround this problem or I need to install Windows 7 again.
private void printButton_Click(object sender, RoutedEventArgs e)
{
string path = Directory.GetCurrentDirectory();
PrintInvoice pi = new PrintInvoice();
pi.DataContext = this.DataContext;
PrintDialog printDlg = new System.Windows.Controls.PrintDialog();
if (printDlg.ShowDialog() == true)
{
pi.Measure(new Size(printDlg.PrintableAreaWidth,
printDlg.PrintableAreaHeight));
pi.Arrange(new Rect(new Size(printDlg.PrintableAreaWidth, printDlg.PrintableAreaHeight)));
pi.Margin = new Thickness(40);
pi.UpdateLayout();
//now print the visual to printer to fit on the one page.
printDlg.PrintVisual(pi, "First Fit to Page WPF Print");
}
Directory.SetCurrentDirectory(path);
}
We have been experiencing a similar problem when some of our customers downgraded to Windows XP. In our case the exception message from the system Event Log was
Framework Version: v4.0.30319
Description: The application requested process termination through System.Environment.FailFast(string message).
Message: Unrecoverable system error
The solution was to install Microsoft XML Paper Specification Essentials Pack on the target machines.

I am using Java JDK 11.0.8 ("Installed JREs" under Eclipse is set to jdk-11.0.8), Eclipse 2020-06, and Codename One 6.0.0.
I have recently switched from JDK 8 to JDK 11 and noticed that playing sounds option in my app does not work anymore...
Note that I uncheck "Java 8" when I create my app and I am only trying to work things out in the simulator (I am not trying to deploy the app to an actual mobile device).
I want to play a "regular sound" (I want to play a sound from beginning to end, and when it ends I do not need to replay it from the beginning) and also a "looping sound" (the sound should come to its beginning when it ends and hence, I can continuously play it in the background).
Hence I have two questions:
Question1 - About "regular sounds"
I would like to create Media object just once and then re-use it whenever I need to play the same regular sound.
For that purpose I am encapsulating a Media creation inside a class as follows:
public class RegularSound {
private Media m;
public RegularSound(String fileName) {
try{
InputStream is = Display.getInstance().getResourceAsStream(getClass(), "/"+fileName);
m = MediaManager.createMedia(is, "audio/wav");
}
catch(Exception e)
{
e.printStackTrace();
}
}
public void play() {
m.setTime(0);
m.play();
}
}
Then I instantiate the RegularSound object and play it as follows:
mySound = new RegularSound("example.wav");
mySound.play();
Please note that example.wav is copied directly under the "src" directory of my project.
This code used to work with JDK 8, but with JDK 11, I get the following build errors:
Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: javax/media/ControllerListener

Question2- About "looping sounds"
For looping sound I have created another class as follows:
public class LoopingSound implements Runnable{
private Media m;
String fileName;
public LoopingSound(String fileName){
try{
InputStream is = Display.getInstance().getResourceAsStream(getClass(), "/"+fileName);
m = MediaManager.createMedia(is, "audio/wav",this);
}
catch(Exception e)
{
e.printStackTrace();
}
}
public void pause()
{
m.pause();
}
public void play()
{
m.play();
}
public void run() {
m.setTime(0);
m.play();
}
}
But I again get build errors when I instantiate an object of LoopingSound and try to play it...
So could you please let me know how to change code for regular and looping sounds so that I do not receive above-mentioned errors when using JDK 11?
UPDATE
Thanks for the reply #shai-almog. I have installed CEF. But I am receiving some messages on the console in runtime and I can't hear the sound playing... I run the following code:
try {
InputStream is = Display.getInstance().getResourceAsStream(getClass(), "/example.wav");
Media m = MediaManager.createMedia(is, "audio/wav");
m.play();
} catch (IOException e) {
e.printStackTrace();
}
and I receive the following messages on console when I run this code (it throws an exception at the end):

UPDATE 2
I could manually add Open JavaFX 11 to Eclipse and to Codename One app running under Eclipse while using JDK 11 as follows:
Step1) Create JavaFX11 user library under Eclipse
Download JavaFX 11 from https://gluonhq.com/products/javafx/
unzip it -> creates javafx-sdk-11.0.2 folder
Create a User Library: Eclipse -> Window -> Preferences -> Java -> Build Path -> User Libraries -> New.
Name it JavaFX11.
Hit "Add External JARs" and include all the jars under javafx-sdk-11.0.2\lib
Step 2) Add the JavaFX11 library to the project:
Right click on project.
Select Build path -> Configure Build Path
Goto Library tab->Add Library->User Library->Check JavaFX11->Apply and Close
Now, I can hear sounds playing in my Codename One application.
However, I need to run my application from command prompt and regular command line to run the apps does not work anymore (the app cannot find the JavaFX related classes from the command prompt and I get the same errors listed above). So could you please tell me how to modify the command line so that Codename One project that uses JavaFX would run from command prompt?
Here is the regular command line I use:
java -cp dist\Proj.jar;JavaSE.jar com.codename1.impl.javase.Simulator com.mycompany.hi.Main
BTW, I have tried to add javafx.media.jar under javafx-sdk-11.0.2\lib to the classpath (-cp) in the command line, but this did not work...
UPDATE 3
We have solved the issue by using the following command line:
java --module-path C:\javafx-sdk-11.0.2\lib\ --add-modules= ALL-MODULE-PATH -cp dist\Proj.jar;JavaSE.jar com.codename1.impl.javase.Simulator com.mycompany.hi.Main
(where C:\javafx-sdk-11.0.2\lib\ is our )
Thanks!
The TL;DR
Either install CEF as explained here or switch to ZuluFX 11 for your VM.
The explanation:
This used to work until we integrated CEF support we would download JavaFX dynamically for JDK 11 installs but this caused a lot of related problems. So we decided to migrate to CEF, this is still in progress and while it's ongoing JavaFX dynamic download is broken. Once it's done CEF will be auto-installed and this will be seamless again.
This impacts browser component and media which are the two components implemented by JavaFX.
I want to create a custom installer for oob applications for Windows and MacOS.
For Windows, I used the following method - https://www.codeproject.com/Articles/179756/Installing-Silverlight-OOB-Application-using-a-Set
For MacOS, the following solution - https://www.blaize.net/2012/04/offline-oob-mac-installation/
These methods work well and create the application, but the application update does not work with them.
In the Silverlight application, I use the following code to update:
private void CheckUpdateApplication()
{
if (Application.Current.IsRunningOutOfBrowser)
{
Application.Current.CheckAndDownloadUpdateAsync();
Application.Current.CheckAndDownloadUpdateCompleted += Application_CheckAndDownloadUpdateCompleted;
}
}
private void Application_CheckAndDownloadUpdateCompleted(object sender, CheckAndDownloadUpdateCompletedEventArgs e)
{
if (e.UpdateAvailable)
{
MessageBox.Show(CommonMethod.MessageUpdateApplication);
}
else if (e.Error != null)
{
MessageBox.Show(string.Format("{0} - {1}", e.Error.GetType().Name, e.Error.Message));
}
}
In the settings of out of browser application, I set the checkbox - "Require elevated trust when running outside the browser". The XAP file is signed with a self-signed certificate.
After installing in Windows, I get the following error when updating:
Exception - Error HRESULT E_FAIL has been returned from a call to a
COM component.
After installing in MacOS, I get the following:
OutOfMemoryException - Error 0x1AA6.
Pass the /origin command line argument to sllauncher.exe
From https://www.codeproject.com/Articles/179756/Installing-Silverlight-OOB-Application-using-a-Set:
This option specifies the Uri where the XAP file have come from. This
Uri is used for security purposes and auto-updates. For example:
/origin: http://mywebsite.com/SampleOOB.xap
This is Windows Forms application.
As in title, I can't debug Task in Visual Studio 2015. If I will check breakpoint at line var a = costam(); it will be hit, but if then I will press step into, or continue, execution will not be continued. This works fine in Console Application. For now i checked, that error appears when I'am trying to run my own method in Task, or if I'am invoking something.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
Task.Run(() =>
{
var a = costam();
});
}
string costam()
{
return "s";
}
}
I would suggest changing the settings to break on any exception in the debug menu, not only uncaught ones. This option is called breaking when the exception is "thrown". Unfortunately the 2015 exceptions menu I'm not familiar with so I can't help you out with that.
There are certain exceptions that are caught and suppressed behind the scenes, especially with WinForms--constructors / load events are particularly shielded. It's likely that it doesn't like spawning a new thread in the UI thread which is why it's throwing an exception in your WinForms application but not the console application. This also explains why "stepping in" "doesn't work"--it steps in but the exception means the next breakpoint isn't hit.
Update 1 to VS2015 seems to solve this issue.
This question already has an answer here:
Launch Silverlight Out-of-Browser from browser post-installation
(1 answer)
Closed 2 years ago.
I'm planning to build a download manager application and would like to be able to launch the application when a user clicks a button the site. The application would obviously already need to be installed on the client machine.
There are a few reasons why this needs to be written using Silverlight, but they're not really relevant to the question. I only mention it so that people don't suggest that I use another technology.
Doing a bit of a mash up from two other posts [1] and [2].
But of course this will only work for Windows not Mac. There you will have to fallback to the #michael-s-scherotter style solution.
private void Button_Click(object sender, RoutedEventArgs e)
{
if (Application.Current.HasElevatedPermissions && System.Windows.Interop.ComAutomationFactory.IsAvailable)
{
string run = "\""%ProgramFiles%\\Microsoft Silverlight\\sllauncher.exe"\" /emulate:"Silverface.xap" /origin:\"http://www.silverlight.net/content/samples/apps/facebookclient/ClientBin/Silverface.xap\" /overwrite";
dynamic cmd = ComAutomationFactory.CreateObject("WScript.Shell");
cmd.Run(run, 1, true);
}
}
Yes. Here is an example:
http://www.silverlight.net/content/samples/apps/facebookclient/sfcquickinstall.aspx
I found a trick that launches the installed silverlight OOB from the silverlight app in-browser. Both applications should be singed and have the elevated trust.
When a user installs the silverlight OOB App first time, retrive the path and argument values from the shortcut file of the OOB app on desktop. (ref: How I can use Shell32.dll in Silverlight OOB) If you know the the path and argument values, you can launch the OOB app using Com Object.
Send the retrive the path and argument values to the silverlight App in-browser. (ref: http://msdn.microsoft.com/en-us/library/dd833063(v=vs.95).aspx)
Store the path and argument values in a cookie.
Now, the silverlight app in-browser is able to launch the silverlight OOB using the path and argument values in the cookie.
using (dynamic shell = AutomationFactory.CreateObject("WScript.Shell"))
{
shell.Run(launchPath);
}
I hope this trick is useful to you :)
It is possible if you agree to install the app each time the user clicks on it.
You also should set the app to require elevated trust in its OOB settings.
Just uninstall the app on startup (for example, in main window constructor):
if (Application.Current.HasElevatedPermissions && Application.Current.InstallState == InstallState.Installed)
{
string launcherPath = string.Empty;
using (dynamic shell = AutomationFactory.CreateObject("Shell.Application"))
{
string launcher64 = #"C:\Program Files (x86)\Microsoft Silverlight";
string launcher32 = #"C:\Program Files\Microsoft Silverlight";
dynamic folder64 = shell.NameSpace(launcher64);
if (folder64 != null)
{
launcherPath = launcher64;
}
else
{
dynamic folder32 = shell.NameSpace(launcher32);
if (folder32 != null)
{
launcherPath = launcher32;
}
}
}
using (dynamic shell = AutomationFactory.CreateObject("WScript.Shell"))
{
var origin = Application.Current.Host.Source.OriginalString;
var launchCmd = string.Format(#"""{0}\sllauncher.exe"" /uninstall /origin:""{1}""", launcherPath, origin);
shell.Run(launchCmd);
}
}
(the code for uninstall was taken from this post: http://www.wintellect.com/blogs/sloscialo/programmatically-uninstalling-silverlight-out-of-browser-application)
I am developing a WPF app that contains a webbrowser control that loads a silverlight application. I would like to be able to launch the app from visual studio (F5) and have the debugger attach to the silverlight code. However, I've not had any luck with this.
The best I can currently do is to launch the app without attaching, then once it is up and running, attach to the process manually with silverlight as the specified type of code to debug, and this works. (When I cause the web browser control to load the silverlight app, it will hit breakpoints in my silverlight code). I've written some macros to automate this launching/attaching somewhat, but it still isn't the best.
I've tried specifying the WPF app as the external program to run when launching/debugging the silverlight app, but Visual Studio attaches to the process wanting to debug the managed .NET code.
Any ideas? Ideally, I would really like to attach to the process and debug both the managed .NET and the silverlight code, but I don't think this is possible. I'd really like to automatically be attached to the silverlight code at launch so that I can easily debug all issues with the silverlight app, including those that occur on load.
Thanks for your ideas Brandorf and fatty. Brandorf's almost gets me to where I wanted to go, but does require that my SL app be capable of running on its own. I really want to have only the one app, which is both wpf and silverlight, with the SL side being debugged.
A long time after I asked this question (I forgot I had asked it here), I actually pieced together a solution that I'm really happy with. I use visual studio automation within the WPF/.NET side of my app, to find all running instances of visual studio, figure out which one produced my exe (since it typically sits in a folder below the vcproj/sln folder), and then use visual studio automation to have that VS attach to the app, debugging silverlight code. After this is done, I then load my silverlight content.
It works really well. You end up with an app that goes and finds a debugger to attach to itself every time it runs (so you probably want this code only in a debug build, or somehow able to be turned off). So you just launch the app with ctrl-F5 (launch without debugging) from visual studio whenever you want to debug the silverlight side.
Here's my code:

It's a bit of a shot in the dark, but assuming your silverlight app is capable of running on its own, you can, under your solution settings, set visual studio to start both apps together, and you should be attached to both of them.
If you can't add the Silverlight project to your solution (which will start debugging automatically), you might be able to make use of this tip. It will load both projects at the same time
