Hello !

I must upgrade my application (process) in a realtime priority.
I work with Win2000 Server (with administrator's rights) and use Borland C++
6, and I try to use the fonction SetClassPriority() but it always return an
error (and GetClassPriority too). And the error returned by GetLastError()
is unexpected, something like : "Window do not have any scrollbar" !!

Is there another way to set a high priority to my process and if possible,
dynamically, to set it "realtime" just for a moment and to restablish the
normal priority after ?

Thanks for your help
Bye

Hi,
May be your code incorrect.
What way do you use?
As a rule I use next:

bool res=SetPriorityClass(
    GetCurrentProcess(),	// handle to the process  
    REALTIME_PRIORITY_CLASS	// priority class value 
   );

if(res ....)


bool res=SetPriorityClass(
    GetCurrentProcess(),	// handle to the process  
    NORMAL_PRIORITY_CLASS	// priority class value 
   );


for current process. Or you want to do it for another 
process?

Vladimir.
