Hi there...

I compile and run:
lpSi = (LPSTARTUPINFO) malloc (sizeof(STARTUPINFO)) ;
lpSi->cb = sizeof(STARTUPINFO) ;
lpPi=(LPPROCESS_INFORMATION)
        malloc(sizeof(PROCESS_INFORMATION));

assert ((CreateProcess(
        NULL,
        pArgStr,
        NULL,
        NULL,
        TRUE,
        0,
        NULL,
        NULL,
        lpSi,
        lpPi)) == TRUE ) ;

but my program fails as assert is FALSE... 

pArgStr is a space-separated string which causes no problem when used in
system(pArgStr), for instance...

I compile with bcc32
        -W for the .obj 
        nothing for the .exe

Have I done something wrong ?   

Hmm... for the X-post, let's say that I think that both groups are
concerned.

Regards

Comprendo ! That's not what's written on my short papers. Do you know
the default parameters for a console application ?
Anyhow I'm going to have a look in a *true* Windows programming book ...
By the way, do you know a good one ?


best regards
