Killing processes

My program currently opens up multiple iexplorer.exe's in the background. Everytime I run it i get around 50 iexplorer.exe processes.

Now I'm hoping to find a way to kill all of them with a single click of a button.
So anyway... anybody know of any code that kills a process in Windows?

TerminateProcess(HANDLE hProcess,UINT uExitCode);

This sort of question can be answered easily by searching the forums. I searched for "kill process" and found the answer.

The only thing I can think of is...

TerminateProcess("iexplore.exe", 0);

That didnt work...
I looked up TerminateProcess and couldnt find anything that really helped me (I'm obviously very new at this):mad:

Here's a snippet from some code of mine.

Code:

---


void EndProcess(int id)
{    HANDLE myHandle;
      DWORD Code;
      PROCESSENTRY32 Proc=myList[id];
      if((myHandle=OpenProcess(PROCESS_ALL_ACCESS, FALSE, Proc.th32ProcessID))==NULL)
      {    MessageBox(hwnd, "Error in OpenProcess", "Error", MB_OK);
            return;
      }
      if(GetExitCodeProcess(myHandle, &Code)==0)
      {    MessageBox(hwnd, "Error in GetExitCodeProcess", "Error", MB_OK);
            return;
      }
      TerminateProcess(myHandle, Code);
      CloseHandle(myHandle);
      return;
}

---

Code:

---

DWORD dwProcessId;
HWND hFind;
HANDLE hProcess;

do
{
        hFind=FindWindow("IEFrame",NULL);
        if (!hFind)
                break;
        GetWindowThreadProcessId(hFind,&dwProcessId);
        hProcess=OpenProcess(PROCESS_TERMINATE,NULL, dwProcessId);
        if (hProcess)
                TerminateProcess(hProcess,0);
}

???????????????????

Perhaps a better question would be "how do I stop so many processes from being created at once"

Could you show the code you have at this time? I can't see why you should be getting this error.

Which line causes the error?

hFind=FindWindow("IEFrame",NULL);

If I remove that it points to any line with "hFind"

What happens if you leave that line in?

The error points to this line

Code:

---

hFind=FindWindow("IEFrame",NULL);

---

And if I remove it then the error points to the next line which has "hFind" in it.

I think the problem must then lie with MFC. I'm not an MFC person, so I can't help you, sorry.

There is no logical reason why an HWND should be interpreted as a CWND *. Could you zip up your source and send it? I could try to run it, but I can't make any guarantees.
