Remarks

Use an edit browse control to select a file or folder name. Optionally, use the control to perform a custom action such as to display a dialog box. You can display or not display the browse button, and you can apply a custom label or image on the button.

The browse mode of the edit browse control determines whether it displays a browse button and what action occurs when the button is clicked. For more information, see the GetMode method.

The CMFCEditBrowseCtrl class supports the following modes.

  • custom mode
    A custom action is performed when the user clicks the browse button. For example, you can display an application-specific dialog box.

  • file mode
    A standard file selection dialog box is displayed when the user clicks the browse button.

  • folder mode
    A standard folder selection dialog box is displayed when the user clicks the browse button.

How-To: Specify an Edit Browse Control

Perform the following steps to incorporate an edit browse control in your application:

  1. If you want to implement a custom browse mode, derive your own class from the CMFCEditBrowseCtrl class and then override the CMFCEditBrowseCtrl::OnBrowse method. In the overridden method, execute a custom browse action and update the edit browse control with the result.

  2. Embed either the CMFCEditBrowseCtrl object or the derived edit browse control object into the parent window object.

  3. If you use the Class Wizard to create a dialog box, add an edit control (CEdit) to the dialog box form. Also, add a variable to access the control in your header file. In your header file, change the type of the variable from CEdit to CMFCEditBrowseCtrl. The edit browse control will be created automatically. If you do not use the Class Wizard, add a CMFCEditBrowseCtrl variable to your header file and then call its Create method.

  4. If you add an edit browse control to a dialog box, use the ClassWizard tool to set up data exchange.

  5. Call the EnableFolderBrowseButton, EnableFileBrowseButton, or EnableBrowseButton method to set the browse mode and display the browse button. Call the GetMode method to obtain the current browse mode.

  6. To provide a custom image for the browse button, call the SetBrowseButtonImage method or override the OnDrawBrowseButton method.

  7. To remove the browse button from the edit browse control, call the EnableBrowseButton method with the bEnable parameter set to FALSE.
