当建立一个对话框的时候，在默认条件下，确定按钮（IDOK）是默认按钮，如果需要改变默认的按钮有两种方法：

其一： 直接在确定按钮（IDOK）的属性里去掉Default button风格的选项

其二： 在运行的时候用代码实现，如：

  //去掉确定按钮（IDOK）的默认按钮

CButton *pokbutton = (CButton *)GetDlgItem(IDOK);

Pokbutton->ModifyStyle(BS_DEFPUSHBUTTON,0);

  //添加IDCANCEL的默认按钮风格

CButton *pcancelbutton = (CButton *)GetDlgItem(IDCANCEL);

pcancelbutton->SetButtonStyle(BS_DEFPUSHBUTTON);

 AfxMessageBox(CurPath);
 
 //
 CString number;
 int len = LineLength(LineIndex(0));
 LPTSTR p=number.GetBuffer(len);
 this->GetLine(0,p,len);
 AfxMessageBox(number);
   得到系统目录 (GetSystemDirectory)

4: 从字符串中提取数字
 CString strNum;
 CString str("测试125各国87kk");
 strNum = GetStr(str);
 AfxMessageBox(strNum);
 
5: 创建无模对话框
 CDlg_Test *aa = new CDlg_Test;
 aa->Create(IDD_DIALOG1,NULL);
 aa->ShowWindow(SW_SHOW);

6: 得到窗口绝对坐标

 CString strNum,strNum1;
 CRect rect;
 GetClientRect(&rect);
 ClientToScreen(&rect);
 strNum.Format("X: %d",rect.top);
 strNum1.Format("   Y: %d",rect.left);
 strNum = strNum + strNum1;
 AfxMessageBox(strNum);
 
7: 复制文件夹
 SHFILEOPSTRUCT  Op;
 
 char FromBuf[]="E://temp/0";
 char ToBuf[]="////SINTEKSERVER//个人文档//陈 伟/0";;
 
 Op.hwnd = NULL;
 Op.wFunc = FO_COPY;
 Op.pFrom = FromBuf;
 Op.pTo = ToBuf;
 Op.fFlags = FOF_NOCONFIRMATION | FOF_RENAMEONCOLLISION ;
 Op.fAnyOperationsAborted = FALSE;
 Op.hNameMappings = NULL;
 Op.lpszProgressTitle = NULL;
 
 if(SHFileOperation(&Op) == 0)
  MessageBox("复制完毕","提示",MB_OK|MB_ICONINFORMATION);

8: 捕获 Ctrl＋鼠标左键 组合
LRESULT CGfdsaDlg::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
 // TODO: Add your specialized code here and/or call the base class
 switch(message)
 {
  case WM_LBUTTONDOWN://????wParam ==
  if (wParam & MK_CONTROL)
   AfxMessageBox("bbb");
  break;
 }
 return CDialog::WindowProc(message, wParam, lParam);
}
 或
 case WM_LBUTTONDOWN:
  if(GetKeyState(VK_CONTROL)<0)
   MessageBox(hwnd,"aaa","bbb",MB_OK);
  break;
