[C++] Window name changer

Serverman · #1 06-30-2009, 04:50 PM

Ok, i made this cool program wich can change a windows name to whatever you want...
Thanks to Tyrano for his (or whoever he stole it from

) debug access code

Code:

#include <windows.h>
#include <iostream>
#include <string>

using namespace std; 
void EnableDebugPriv( ) //Thanks to Tyrano for this...
 {
	 HANDLE hToken;
	 LUID sedebugnameValue;
	 TOKEN_PRIVILEGES tkp;
	 OpenProcessToken( GetCurrentProcess( ), TOKEN_ADJUST_PRIVILEGES |TOKEN_QUERY, &hToken );
	 LookupPrivilegeValue( NULL, SE_DEBUG_NAME, &sedebugnameValue );
	 tkp.PrivilegeCount = 1;tkp.Privileges[0].Luid = sedebugnameValue;
	 tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
	 AdjustTokenPrivileges( hToken, false, &tkp, sizeof( tkp ), NULL, NULL );
	 CloseHandle( hToken );
 } 
int main()
 {

	 SetConsoleTitle("Window namechanger");
	 cout << "Enter window name" << endl;
	 string what;
	 getline (cin, what);
	 EnableDebugPriv();
	 HWND hWindow = FindWindow(NULL,what.c_str());
	 if(!hWindow)
		 {
			 cout << "Window not found" << endl;
			system( "pause" );
			return 1;
		 } 
	  cout << "Thank you, Found Process, attempting to get PID" << endl;
	  DWORD pid;
	  GetWindowThreadProcessId( hWindow, &pid );
	  HANDLE hOpen = OpenProcess( PROCESS_ALL_ACCESS, false, pid );
		 if( !hOpen )
			 {
			    cout << "Can't open process." << endl;
				system( "pause" );
				return 1;
			 } 
		 cout << "Success! Got PID, insert new window name"<< endl;
		 getline (cin, what);
		 SetWindowText(hWindow,what.c_str());
		 hWindow = FindWindow(NULL,what.c_str());
		 if(!hWindow)
		 {
			cout << "Error occured...." << endl;
			system( "pause" );
			return 1;
		 }
		 else
		 {
			 cout << "Name changed successfully"<< endl;
			 for(;;) {
				 if (!FindWindow(NULL,what.c_str()))
				 {
					SetWindowText(hWindow,what.c_str());
				 }
			 }
			 system( "pause");
		 }
		 return 0;

}

I've compiled it with Visual C++, but i think it should work with any standard c++ compiler...
The .exe is included. BTW, it is cpu heavy if you leave it running after the namechange... The problem is that some programs change the title back, but if you dont care about that, heres a code wich will not keep on changing it all the time

Code:

#include <windows.h>
#include <iostream>
#include <string>

using namespace std; 
void EnableDebugPriv( )
 {
	 HANDLE hToken;
	 LUID sedebugnameValue;
	 TOKEN_PRIVILEGES tkp;
	 OpenProcessToken( GetCurrentProcess( ), TOKEN_ADJUST_PRIVILEGES |TOKEN_QUERY, &hToken );
	 LookupPrivilegeValue( NULL, SE_DEBUG_NAME, &sedebugnameValue );
	 tkp.PrivilegeCount = 1;tkp.Privileges[0].Luid = sedebugnameValue;
	 tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
	 AdjustTokenPrivileges( hToken, false, &tkp, sizeof( tkp ), NULL, NULL );
	 CloseHandle( hToken );
 } 
int main()
 {

	 SetConsoleTitle("Window namechanger");
	 cout << "Enter window name" << endl;
	 string what;
	 getline (cin, what);
	 EnableDebugPriv();
	 HWND hWindow = FindWindow(NULL,what.c_str());
	 if(!hWindow)
		 {
			 cout << "Window not found" << endl;
			system( "pause" );
			return 1;
		 } 
	  cout << "Thank you, Found Process, attempting to get PID" << endl;
	  DWORD pid;
	  GetWindowThreadProcessId( hWindow, &pid );
	  HANDLE hOpen = OpenProcess( PROCESS_ALL_ACCESS, false, pid );
		 if( !hOpen )
			 {
			    cout << "Can't open process." << endl;
				system( "pause" );
				return 1;
			 } 
		 cout << "Success! Got PID, insert new window name"<< endl;
		 getline (cin, what);
		 SetWindowText(hWindow,what.c_str());
		 hWindow = FindWindow(NULL,what.c_str());
		 if(!hWindow)
		 {
			cout << "Error occured...." << endl;
			system( "pause" );
			return 1;
		 }
		 else
		 {
			 cout << "Name changed successfully"<< endl;
			/* for(;;) {
				 if (!FindWindow(NULL,what.c_str()))
				 {
					SetWindowText(hWindow,what.c_str());
				 }
			 }*/
			 system( "pause");
		 }
		 return 0;

}

You will have to compile the last one yourself

Gosh you are pro :0 Nah, GJ for a C++ nub like you

Serverman · #3 06-30-2009, 04:59 PM

Psssh! You do it better!

...Why do you get debug privileges and open the process? You realize that neither of those are necessary to change a window's title?

On another note, you do a for(;

to loop indefinitely, which is fine, but you should insert a Sleep(1) at the very least to make this process not take up 100% of the processor.

Serverman · #5 07-06-2009, 02:11 PM

Yes, i was thinking about that...
BTW... It won't find the window without debug access...
And putting in the sleep helped alot, went from 99% CPU usage down to 00% hehe...

too

FindWindow should work fine without debug access; it's OpenProcess that fails without proper access, but the only reason to use OpenProcess is to obtain a HANDLE, which is unnecessary to modify a window's title (a HWND type).

Serverman · #7 07-06-2009, 06:25 PM

Uhm, without the handle, how can i control the process?

Darimus · #8 07-07-2009, 07:06 AM

All that's necessary to change the window title is the SetWindowText function, (internally, a SendMessage call using WM_SETTEXT), which doesn't require debug privileges, nor a HANDLE parameter.

Clever boy.... I'll try it sometime
