MFC控常用控件操作源码

1. 文件夹选择框

 1     TCHAR pszPath[MAX_PATH];  
 2     BROWSEINFO bi;   
 3     bi.hwndOwner      = this->GetSafeHwnd();  
 4     bi.pidlRoot       = NULL;  
 5     bi.pszDisplayName = NULL;   
 6     bi.lpszTitle      = TEXT("请选择文件夹");   
 7     bi.ulFlags        = BIF_RETURNONLYFSDIRS | BIF_STATUSTEXT;  
 8     bi.lpfn           = NULL;   
 9     bi.lParam         = 0;
10     bi.iImage         = 0;
11     LPITEMIDLIST pidList = SHBrowseForFolder(&bi);  
12     if ( pidList == NULL ) {  
13         return;  
14     }
15     if ( SHGetPathFromIDList(pidList, pszPath) ) {  
16         m_strPcDir = pszPath;
17         SetDlgItemText( IDC_EDIT_PCDIR, m_strPcDir.GetBuffer(0) );
18     }

2. 文件选择对话框

 1 CFileDialog dlgFile(TRUE);
 2 CString fileName;
 3 const int c_cMaxFiles = 100;
 4 const int c_cbBuffSize = (c_cMaxFiles * (MAX_PATH + 1)) + 1;
 5 dlgFile.GetOFN().lpstrFile = fileName.GetBuffer(c_cbBuffSize);
 6 dlgFile.GetOFN().nMaxFile = c_cMaxFiles;
 7 
 8 dlgFile.DoModal();
 9 m_strSecondSrcFile = fileName;
10 fileName.ReleaseBuffer();

3. 对话框全屏（基本操作流程：获取桌面对话框属性 ----> 调用SetWindowPos()根据桌面对话框的属性设置对话框大小和位置）

BOOL CBaseDialog::OnInitDialog()
{
    CDialog::OnInitDialog();
    /* 全屏化对话框*/
    HWND hDeskTopWnd=::GetDesktopWindow(); 
    CRect rect;
    ::GetWindowRect(hDeskTopWnd, &rect);
    SetWindowPos(&wndTopMost, rect.left, rect.top, 
　　　　　　rect.right-rect.left, rect.bottom-rect.top, 0);
　　return TRUE;  // return TRUE unless you set the focus to a control
    // 异常: OCX 属性页应返回 FALSE
}

4. 设置对话框元素焦点

GetDlgItem(IDC_COWADDINFO_ENTERTIME_EDIT)->SetFocus();

5. ComoBox操作

    ((CComboBox*)GetDlgItem(IDC_COMBO_BOARD))->InsertString(0, L"0");
    ((CComboBox*)GetDlgItem(IDC_COMBO_BOARD))->InsertString(1, L"1");
    ((CComboBox*)GetDlgItem(IDC_COMBO_BOARD))->InsertString(2, L"2");
    ((CComboBox*)GetDlgItem(IDC_COMBO_BOARD))->InsertString(3, L"3");
    ((CComboBox*)GetDlgItem(IDC_COMBO_BOARD))->SetCurSel(0);
