Thread: Cast from hwnd

I want to loop trough all the windows running and get their hwnd and convert it to an int. Here is the function I have that attempts to do this (very similar to code i have previously posted):

Code:

int getProcesses(HWND hwnd) {

	HMODULE hModule;
	char szProcessName[MAX_PATH] = {0};
	DWORD dwProcesses[1024], cbNeeded, cProcesses;
	unsigned int i;
	char PIDbuf[128];

	if (!EnumProcesses(dwProcesses, sizeof(dwProcesses), &cbNeeded))
		return -1;
	cProcesses = cbNeeded / sizeof(DWORD);
	for (i = 0; i < cProcesses; i++)
		if(dwProcesses[i] != 0)
		{
			HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION |
				PROCESS_VM_READ, FALSE, dwProcesses[i]);
			if (NULL != hProcess)
			{
				strcpy(szProcessName, "System");
				if (EnumProcessModules(hProcess, &hModule, sizeof(hModule),
					&cbNeeded))
				{
					GetModuleBaseName(hProcess, hModule, szProcessName,
						sizeof(szProcessName)/sizeof(CHAR));
				}
			sprintf(PIDbuf, "%d : %s", (int)hProcess, szProcessName);
			SendDlgItemMessage(hwnd, 1000, LB_ADDSTRING, 0, (LPARAM)PIDbuf);
			}
			CloseHandle(hProcess);
		}
	return cProcesses;
}

The problem is that all the hwnds are the same (1952) and using hModule doesn't work either. I am pretty sure that hProcess is the hwnd. All the process names work fine and the ListView works.

Sorry I want to print out the Window handle, not the Process ID, Spy and Spy++ both do this, printing the window handle (hwnd) in hex.

abachler, void main? What's the reason for void main?
