Er, disabling cheat engine from running with my trainer?

[drlunar]

I'd like my trainer to detect and close CE, or even just kill the client if CE is detected. I'd like to do this for tampering reasons of course, if you have any ideas please do help me. I'd be quite grateful, and I'd like to thank anyone who does in advance.

As a rule you should not close CE when you detect it presence, instead you should close your own program. Like this:

void CheckCEPresent(){
HANDLE hSnap = CreateToolhelp32Snapshot( TH32CS_SNAPPROCESS, NULL ) 
PROCESSENTRY32  p = { NULL };

if( hSnap == INVALID_HANDLE_VALUE ){
  printf("Error: Failed to open a snapshot of all the processes running\n");
return;
}
if( !Process32First( hSnap, &p ) ){
   printf("Error: Failed to enumerate first process running\n");
}

do{
   if( !strcmp(  (char*)&p.szExeFile, "ce.exe" ) ){   // strcmp returns 0 when the strings are equal
     printf("CE.exe found, exiting!\n");
     exit( 0 );
   }

} while( Process32Next( hSnap, &p ) );

}

I wrote this from the top of my head, but this is the general idea. Simply execute this function every few seconds, once CE shows up in your process list the program exits.

I couldn't get your example to work, though thank you for the reply. If possible can you help me with IsWindow()? I'm currently trying the following;

HWND hWnd = FindWindowA("Cheat Engine", NULL);
		
IsWindow(hWnd);
{
	MessageBox:: Show ("Cheat Engine has been detected running on this system","");
	exit(0);
}
		 }

It doesn't search for Ce and spams the messagebox.

Do it like this:

if( hWnd ){
MessageBox( "Cheat Engine has been detected running on this system" );
}

I don't know the marco IsWindow(). But FindWindow() returns either a handle to the found window, or null.

For some odd reason it isn't working

void Form1::Form1_Load.. {
HWND m_hWnd = FindWindowA("Cheat Engine 6.2", NULL);
	if( m_hWnd ) {
MessageBox:: Show ( "Cheat Engine has been detected running on this system","");
Close();
}
}

Ahh I see your problem.

FindWindowA(NULL, "Cheat Engine 6.2");

There you go, the first param is the class name not the window tittle.
