 |
|
i have done the following function:
| Code: |
int AttachToWindow(char* WindowName)
{
hWindow = FindWindow(0, WindowName);
GetWindowThreadProcessId(hWindow, &dwPID);
hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwPID);
if(!hWindow || !hProcess)
{
cout << "Error opening the process" << endl;
return 0;
}
else
{
cout << name << " opened!" << endl;
return 1;
}
}
|
but now im having trouble creating the function:
AttachToProcess(char* ProcessName)
i need something like the first function AttachToWindow(char* WindowName), so i can enter a Process name (like "cmd.exe").
can some 1 help me with that?

On a side note to your currently posted code:
| Code: |
hWindow = FindWindow(0, WindowName);
GetWindowThreadProcessId(hWindow, &dwPID);
hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwPID);
if(!hWindow || !hProcess)
|
It is completely pointless to have error checking after attempting to use a variable. Don't bother including error checking if you aren't going to use it properly.
Also don't use PROCESS_ALL_ACCESS either, specify the needed flags.
