Re: 自動按鍵的 win32 程
原文恕刪..
我寫了一個簡單的範例, 假設你要關閉的對話框長這樣..
http://ppt.cc/oyLR
接著都在調用 ::FindWindow, ::FindWindowEx, ::SendMessage,
::PostMessage, ::ShowWindow, ::DestroyWindow... etc 函式,
實做簡單範例碼連結： http://nopaste.csie.org/d9e6e
簡單的範例碼如下：
#include <windows.h>
#include <stdio.h>
#include <stdio.h>
#define BUFFER_LEN 200
int main()
{
const char *WindowName = "MFC_T";
const char *ButtonName = "Button1";
char WindowClassName[BUFFER_LEN];
char ButtonClassName[BUFFER_LEN];
HWND WindowWnd = NULL;
HWND ButtonWnd = NULL;
// ================================================
// Window
WindowWnd=::FindWindow(NULL, WindowName);
if(WindowWnd==NULL) {
printf("can't find %s window.\n", WindowName);
return EXIT_FAILURE;
}
GetClassName(WindowWnd,WindowClassName ,200);
printf("Windows Class:%s\n", WindowClassName);
// hide 1 sec, and show it
::SetForegroundWindow(WindowWnd); // set active window
printf("window hide and show...\n");
Sleep(1000),
::ShowWindow(WindowWnd, SW_HIDE);
Sleep(1000);
::ShowWindow(WindowWnd, SW_SHOW);
// ================================================
// Button
ButtonWnd = ::FindWindowEx(WindowWnd, NULL, NULL, ButtonName);
if(WindowWnd==NULL) {
printf("can't find %s window.\n", WindowName);
return EXIT_FAILURE;
}
GetClassName(ButtonWnd,ButtonClassName ,200);
printf("Button Class:%s\n", ButtonClassName);
// we'll destroy the window
// once you destroy any object, you can't use that any more.
UINT msg = WM_CLOSE;
Sleep(1000), printf("Close Now..\n");
::SendMessage(WindowWnd,msg, NULL, NULL);
printf("Have Close...\n");
return EXIT_SUCCESS;
}
上面要注意的是, 如果你的視窗還沒跑完
(或已畫出來,但實際上還沒初始化完之類問題)
你用 ::FindWindow 會找不到,
所以根據你的例子比較建議用
while(WindowWnd!=NULL){
WindowWnd = ::FindWindow(NULL, WindowName);
};
當然比較聰明的做法或許是用 CALLBACK 方式就不會被綁死.
使用前請先評估這是不是真的是你唯一解決的方式,
我自己測是覺得抓失敗的機會還是有的,
常常 SendMessage, PostMessage, Sleep(xxx) 在那裡調來調去.
參考看看吧.
