Waiting function

Sup
I wanna know if there is any way make the program wait for a process.
I was about to use while,but it's blocking the execution of the program,so...

There is a button which is waiting the process and then it doing its stuff.
The program is a window application and using dialogs

Code:

case IDC_BUTTON1:        v Process
        while(isRunning("S4Client.exe")==false){}
                 ^The waiting func

You cannot wait in that case-block, since you are within the message loop of a window and it wouldn't react anymore, if you did.
You could use a thread or a timer; since it's just that little task, i would tend to use the timer. You create a timer that ticks every 100ms and add a handler for it to your message loop.

I've never tried this before but it should be possible to install a global windows hook which receives a notification when the S4Window has been created:

>> [Only registered and activated users can see links. Click Here To Register...]
>>[Only registered and activated users can see links. Click Here To Register...]

Use Autoit library so you can it easy.

You may use Autoit function in C++ or?
EDIT: Tried but again it's freeze

Use this.
While(true)
{
if(ProcessExists("S4") == true)
{
"successs";
}
}

You clearly did not understand the problem.

Plz not :<

@Topic:
Create a thread: [Only registered and activated users can see links. Click Here To Register...]

And let it check every, for instance 100ms, if the Process is running
with [Only registered and activated users can see links. Click Here To Register...] .
(I know a new thread isnt the best way to do this, but it should work)

The thread i should make at begin of program?
Cause the users should choose by checkboxes and then button should wait process etc.

Code:

If (Checkbox == checked)
{
    CreateThread
}
if (Checkbox != checked)
{
    SuspendThread or TerminateThread
}

The thread runs the loop to check if the Process is running.

The Correct way:

[Only registered and activated users can see links. Click Here To Register...]
to get the Handle of the process, use 'PROCESS_ALL_ACCESS', and inherit the handle (second parameter true).

[Only registered and activated users can see links. Click Here To Register...]
pass the handle and the maximum time you wish to wait.

[Only registered and activated users can see links. Click Here To Register...]
Create an Event after the WaitForSingleObject call to notify your main thread.

Put these three calls in a function and in your main thread you just let yourself be notified via the event you set up (see MSDN).

Finally, call [Only registered and activated users can see links. Click Here To Register...] on that function. Once the target application terminates, your secondary thread will unblock and create an event which notifies your main thread.

Impossible, S4 is protected by XTrap, a long time before the window is created and i am damn sure, he wants to write a trainer.

Here how to do that with a thread

Code:

DWORD WINAPI Thread(LPVOID lpParam)
{
UNREFERENCED_PARAMETER(lpParam);

while(isRunning("S4Client.exe")==false)
Sleep(100);

//do ur stuff

return TRUE;
}

case IDC_BUTTON1:        
        CreateThread(NULL, NULL, Thread, NULL, NULL, NULL);
        break;
