I am trying to set the priority of all instances of an application such as Excel.exe to below normal. When I do this with wscript, it's very slow. I can do it for an open excel by running
SetPriorityClass(GetCurrentProcess(), BELOW_NORMAL_PRIORITY_CLASS );

How can I generalize it below?

char * pProcessName="Excel.exe";
if (hSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0)) == INVALID_HANDLE_VALUE)
else {
    while((Process32Next(hSnap, &proc32)) == TRUE) {
        if(_stricmp(proc32.szExeFile, pProcessName) == 0) {
            HANDLE h=OpenProcess(PROCESS_ALL_ACCESS, TRUE, proc32.th32ProcessID); //this line is incorrect I think
            SetPriorityClass(h, BELOW_NORMAL_PRIORITY_CLASS );

You could try to use PROCESS_SET_INFORMATION as the first parameter... :)
