Error: Failed to set the specified COM apartment state & Canon EDSDK
Hi~~
I am trying integrate Canon EDSDK with Unity3D (5.6.1) by referencing Canon EDSDK's Visual Studio project from >> https://www.codeproject.com/Articles/688276/Canon-EDSDK-Tutorial-in-Csharp << , created by "Johannes Bildstein".
In his project, it will call thread.SetApartmentState when creating thread. And I found that my project is not functioning after I convert the visual Studio UI to Unity UI.
There are NO error message when testing on Unity Editor and Unity's log.txt file. But "Failed to set the specified COM apartment state" was show in output_log.txt after I build and run the project in .exe.
After that, I try to delete the line (`thread.SetApartmentState(ApartmentState.STA);`) or change the STA to MTA or Unknown but the project still not functioning after build the ".exe" . However, the project is functioning in Editor after I modify the code. Any idea why this happening?
More Detail:
In Johannes Bildstein's visual studio project has a class call STAThread for handling mainThread object. To create mainThread object, STAThread has a method CreateThread to create mainThread object.
public static Thread CreateThread(Action action){
var thread = new Thread(new ThreadStart(action));
thread.SetApartmentState(ApartmentState.STA);
return thread;
}
public void Start() {
lock (runLock) {
if (!isRunning) {
mainThread = CreateThread(ExecutionLoop);
isRunning = true;
mainThread.Start();
WaitForThread();
}
}
}
