check running processes in Windows

[gzlzj]

How can I check the running processes in Windows with C++, so that I can avoid running my application again when I double click it several times. Thanks.

Here an example
===========================================================
WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
{
int Mutex;
Mutex= (int) CreateMutex(NULL,true,GetPrevInstMutexName()); // Check if an Instance of the Programm running
if((Mutex != NULL) && (GetLastError()==0)) //if not start Program
{
try
{
Application->Initialize();
.
.
-
Application->Run();
}
catch (Exception &exception)
{
Application->ShowException(&exception);
}
}
return 0;
==========================================================
