最近需要模拟人员去按步骤自动操作某些程序，其中需要用到Win32 API,需要用到辅助工具Microsoft Spy++（WM_COMMAND）去获取程序操作过程的句柄或命令.
//–寻找某个窗体
IntPtr frmHandle = WIN32Util.FindWindow(“{类名}”, “{标题}”);
if (frmHandle == IntPtr.Zero)
throw new Exception(“Frame is not running.”);
//–执行某个命令
int result1 = WIN32Util.PostMessage(frmHandle, 0x0111, 0x000F, 0);
//–寻找弹出对话框
IntPtr Confirm = WIN32Util.FindWindow(“#32770”, “Confirm”);
if (Confirm == IntPtr.Zero)
throw new Exception(“Not Confirm Confirm Frame);
//–寻找子窗体
IntPtr Edit = WIN32Util.FindWindowEx(Confirm, IntPtr.Zero, “Edit”, null);
//–给子窗体的Edit自动输入字符串
string sKill = “KILLALL”;
InputStr(Edit, sKill);

Thanks for the sensible critique. Me & my neighbor were just preparing to do a little research about this. We got a grab a book from our area library but I think I learned more clear from this post. I am very glad to see such wonderful info being shared freely out there. ccfgkdadbbgf
