I have just started using the Visual Studio C++.NET.  I used to use Visual Age by IBM.  My program uses mutitasking and I can't get the _beginthread correct.

My command is "_beginthread(update_db_thread,0,(void *)thread_index);"  where update_db_thread is the name of the thread and thread_index is an integer i am passing to the thread.  

I get the following error "c:\C++\MAIS704\MAIS704.cpp(944): error C2664: '_beginthread' : cannot convert parameter 1 from 'void (int)' to 'void (__cdecl *)(void *)'.  
Do I have to cast the name or am I doing something else wrong.  ???  If so how does the cast statement look.

The prototype of update_db_thread() has to be

void update_db_thread(void *pParam);

You can cast the pParam to an integer if you want.

void update_db_thread(void *pParam)
{
    int nParam = (int)pParam;
}
