So you''re saying that the code compiles all right, and everything, only when you try to run it, the program opens but can''t be brought to the foreground? That''s really weird...
I use Case 1 to spawn notepad from one of my programs...pretty much exactly the same as you are except that I set the second parameter to NULL, like so:

const char *lpFile = "c:\\windows\\notepad.exe";
const char *lpParameters = "error.log";
const char *lpDirectory = ".\\";

ShellExecute(iParms->hwnd,NULL,lpFile,lpParameters,lpDirectory,SW_SHOWNORMAL);


which gets notepad to open the file error.log in the current directory just great. I don''t remember off-hand what the second paramater is supposed to do, (initial properties of the program?) but maybe that has something to do with it.

int ExecuteCommand(char *cmd, int cmdShow)
{

STARTUPINFO startInfo;
int processStarted;
unsigned long result;
PROCESS_INFORMATION pi;

memset(&startInfo, 0, sizeof(STARTUPINFO));

startInfo.dwFlags = STARTF_USESHOWWINDOW;
startInfo.wShowWindow = cmdShow;

processStarted = CreateProcess(NULL, cmd, NULL, NULL, 0,
CREATE_NEW_PROCESS_GROUP | NORMAL_PRIORITY_CLASS,
NULL, NULL, &startInfo, &pi);

if ( processStarted == 0 ) {
return -1;
}

WaitForSingleObject(pi.hProcess, INFINITE);

result = 0;

if ( !GetExitCodeProcess(pi.hProcess, &result) ) {
// STILL_ACTIVE ??
// Impossible to get the exit code for command\n%s
return -1;
}

return result;

}

yes, it usually is a bug in the operating system when a novice programmer tries something and it doesn''t work.. c''mon.
