Which Windows version are you running on?

Where did you save your project to?

I sometimes get an error like this if I run code from the IDE and then edit the source and try to execute the code again.

Make sure that an instance of the console application is not already running before recompiling and testing it.

I get that message a lot...
It's almost always because the program I'm working on is running.

Cruel way to stop process.
Add this program to Tools menu with Arguments: $(TargetPath)

Code Select Expand

#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <tlhelp32.h> // CreateToolhelp32Snapshot()

TCHAR szAppName[] = "ProcKill";

#pragma lib "psapi.lib"

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpszCmdLine, int nCmdShow)
{
HANDLE hSnapShot;
HANDLE hProcess;
PROCESSENTRY32 pEntry;
TCHAR szTmp[260];

if (!*lpszCmdLine) {
MessageBox(0, "Usage: ProcKill.exe <file>", szAppName, MB_OK);
return 1;
}

hSnapShot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
if (hSnapShot) {
pEntry.dwSize = sizeof(pEntry);
if (Process32First(hSnapShot, &pEntry)) {
do {
wsprintf(szTmp, "%d %s", pEntry.th32ProcessID, pEntry.szExeFile);
if (!lstrcmpi(pEntry.szExeFile, lpszCmdLine)) {
// found it
if (MessageBox(0, pEntry.szExeFile, szAppName, MB_OKCANCEL) == IDOK) {
hProcess = OpenProcess(SYNCHRONIZE|PROCESS_TERMINATE, FALSE, pEntry.th32ProcessID);
if (hProcess) {
TerminateProcess(hProcess, 0);
CloseHandle(hProcess);
}
}
}
} while (Process32Next(hSnapShot, &pEntry));
}
CloseHandle(hSnapShot);
}
return 0;
}

This code try to close it first normally with WM_CLOSE

Or you could use FindWindow using the window title and sent it WM_Close

What is actually in this line:

Building for.exe

You can tick Verbose build from Project options... to see that polink.exe commandline.
