Hi,
I need: Get Handle of Main Window from process handle.

Here is the answer....

1. - Use GetProcessId() to get process id from process handle.

Use EnumWindows() to look at each top-level window.
For each top-level window call GetWindowThreadProcessId() to get the thread id and process id that was used to create the window.
Break when you find a top-level window that was created by the specified process handle/id.
2. - Use GetWindowThreadProcessId() to get the thread id and process id that was used to create the window.

...........
thanks

Hi,

here is another tips,

When debugging, you can single step into functions by pressing F11.

To break the debugging, press Ctrl+F5(this is to run the same application for debugging)

Hi,


#include<windows.h>

int_stdcall WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpszCmdLine,int nCmdShow)

{
MessageBox(0,"HELLO","TITLE",0);
return 0;

}
This program is not running it produces an error

syntax error : missing ';' before identifier 'WinMain'
error C2501: 'int_stdcall' : missing storage-class or type specifiers
fatal error C1004: unexpected end of file found
Error executing cl.exe.

How to I solve it.

Hi,

I hope you have started VC application wrongly. Here is the steps to run the WinMain. It is a Win32 Application. Follow the steps

1. New Project -> In Project tab, select Win32 Application
2. In your source code file for en example, if you started the project as test, then edit "test.cpp"
3. Add your Message box.

#include "stdafx.h"

int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
// TODO: Place code here.
MessageBox(0,"Hello","Title",0);

return 0;
}

thanks
