ShellExecute SW_HIDE option is not hiding the exe

If i use ShellExecute API to execute "Notepad.exe" with SW_HIDE. It is executing notepad and the notepad is not visible but while checking in Taskmanager it is in running state. But when i try to run other exe with SW_HIDE option, the exe is not hiding. It is visible as in SH_SHOW option.

ShellExecute( NULL, NULL, "Notepad.exe", NULL, NULL, SW_HIDE );
This is working fine

ShellExecute( NULL, "open","checkingexe.exe", NULL, "C:\\check", SW_HIDE );
This displays the exe, It is not hiding this exe.

Can anybody clarify my doubt

Do you have the code to chekingexe.exe?

Just a guess that it may again be showing the window after the command line is processed.

Can anybody clarify my doubtMy guess: The app window is initially hidden, but receiving the DDE "open" command (that you are sending) makes it visible again.

checkingexe.exe is a simple dialogwindow. Just for testing purpose i created it. It is a simple MFCAPPwizard->dialog window

There is a line in the code telling it be visible again thats all,
while notepad doesnt have this explicit line.

But i need to execute this exe without making it visible to user. Because during the Sevice start i have to invoke this exe.
Will there be any API's helpfulf to do this. I tried using CreateProcess but that is also again displaying the exe. It is not hiding it.

It is not hiding it.Well, in this case, why are you creating a dialog for it at all? I mean, just create an application without any visible UI. A "dialog based" app is not suitable for this, since it displays a modal dialog.

The nShowCmd argument is passed on to the spawned applications entrypoint:

int WinMain(
HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow
);
Your application must used the value passed here to determine whether is should be visible or not.

BTW, it's not the exe that is shown or hidden, but the main window of the application. ;)

There is also a way to run a dialog app in hidden mode, and a flag that will keep a Icon from showing in the task bar.
