Waiting function

[Krasti]

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

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:

Polling is...

Use Autoit library so you can it easy.

Use timer?SetTimer or?

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

[Naworia]

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

You clearly did not understand the problem.

Plz not :<


@Topic:
Create a thread:

And let it check every, for instance 100ms, if the Process is running
with .
(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.

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:


to get the Handle of the process, use 'PROCESS_ALL_ACCESS', and inherit the handle (second parameter true).


pass the handle and the maximum time you wish to wait.


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 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 **** sure, he wants to write a trainer.

Nope, it's wrong, he wants to wait untill S4 starts and not untill it terminates.

Here how to do that with a thread

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;

I put the stuff i wanna do in a function,but the IsDlgButtonChecked isn't work.
I mean after the while,i made it,but it didn't do anything...I hope you get me

Did your programm freez or what ?
It shouldn't freeze if you do ur stuff in a thread.
