Hi all,

I have few problems with the CreateThread function. I am using a frame
grabber; to acquire an image I have to create a thread with the function
CreateThread. Here is my code :

threads_hdls[0] = CreateThread(NULL,0,GrabWithoutCallback,
&user_card[0], 0,NULL) ;

with the function :

DWORD WINAPI TFrameGrabber::GrabWithoutCallback(LPVOID _param)

When compiling, I have the following error messages :

Cannot convert unsigned long(stdcall*(_closure)(void*))(void *) to
unsigned long (__stdcall*)(void*)
Type mismatch in lpStartAdress in call to __stdcall
CreateThread(_Security_Attributes....)

I don't see where is the problem as the function GrabWithoutCallBack is
defined as requested by CreateThread ....

Many thanks in advance.

Christophe
