Application.Run C# equivalent

[GregJ7]

The present WPF equivalent of what used to be:

BOOL bRet;

while( (bRet = GetMessage( &msg, hWnd, 0, 0 )) != 0)
{
if (bRet == -1)
{
// handle the error and possibly exit
}
else
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}

That is,

public class Application {
private void Run() {

    // What code has Microsoft put here?

}

}

That is Win32, not .NET, and the .NET equivalent is handled inside the framework.

You would have to ask Microsoft. Or buy an MSDN developer subscription which gives you access to their source code.

Has anyone that knows what WPF Application.Run() does written a C# function that duplicates what it does? Can you point me to that code? Thanks.

I already told you the answer. I also suggested that you explain what problem you are trying to solve.

[GregJ7]

Where did you tell me everything what Application.Run() does and how it does it? If you can't understand my question or don't know the answer to my question, then I would like an answer from someone who does.

I told you where to find the information. Whatever that method does is internal to Microsoft, so they are the people to answer the question. What you have still not done, is to explain exactly what problem (if you actually have one) you are trying to solve.

You could always take a look at the publicly available[^] reference source code.

I'm old. That took me a minute to translate :) You are most welcome.

Thanks. I found what I wanted in the Dispatcher class (which class Application uses). I needed to see more than I thought, because there is so much important code, however, what I originally was looking for was basically the following in Dispatcher.PushFrameImpl():

while(frame.Continue)
{
if (!GetMessage(ref msg, IntPtr.Zero, 0, 0))
break;

TranslateAndDispatchMessage(ref msg);

}

From this code I was led to learn about thread Frames and such.
