How to Add Controls in MFC

One common method of adding controls in MFC is through the resource editor. Here are the general steps for adding controls:

1. .rc is an abbreviation commonly used in computer programming to refer to a configuration file.
2. Conversation
3. Choose the location on the dialog box where you want to add a control, and select the appropriate control tool from the toolbar (such as a button, edit box, list box, etc.).
4. Click and drag to create a control on the dialog box and adjust its size and position.
5. Set the properties of the control in the attribute window, including the control’s ID, style, initial text, etc.
6. Save the changes and recompile your project.

In addition to using a resource editor, you can also dynamically add controls at runtime through programming. This involves creating instances of control classes in MFC (such as CButton, CEdit, etc.) and adding them to a dialog. You can set the control’s properties when needed and handle its events.
