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：

HWND QQID = NULL, QQPASS =NULL;
