获取进程的句柄

获取进程的句柄

由进程文件名获取：

void fnget_proc_handl(const char *pproc_name)
{
    void *hproc = NULL;
    void *hsnap = NULL;
    PROCESSENTRY32 pe32 = {0};
    pe32.dwSize = sizeof(PROCESSENTRY32);

    hsnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
    if(hsnap == INVALID_HANDLE_VALUE)
	return ;
    if(!Process32First(hsnap,&pe32))
    {
	CloseHandle(hsnap);
	return ;
    }
    do
    {
	if(_stricmp(pe32.szExeFile,pproc_name) != 0)
            continue;
	hproc = OpenProcess(PROCESS_ALL_ACCESS,FALSE,pe32.th32ProcessID);
        if(hproc != NULL)
        {//取到句柄
        }
        CloseHandle(hproc);
    }while(Process32Next(hsnap,&pe32));
    CloseHandle(hsnap);
    return ;
}

由窗口名获取 ：

void fnget_proc_handl(const char *ptitle)
{
    unsigned long dwpid = 0;
    void *hproc = NULL;

    HWND hWnd = FindWindow(NULL, ptitle);
    if (hWnd == NULL)
        return;

    GetWindowThreadProcessId(hWnd, &dwpid);

    hproc = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwpid);
    if(hproc != NULL)
    {//取到句柄
    }
    CloseHandle(hproc);
}
