Linking Variable to MFC Edit Box: Guide

To connect a variable to an MFC edit box, you can use the Class Wizard to associate the variable with the control ID of the edit box. Here are some simple steps:

1. Open the Class Wizard by accessing it through the menu by clicking on View -> Class Wizard or by using the shortcut Ctrl + W.
2. In Class Wizard, choose the dialog class (e.g. CMyDialog) to which you want to connect the variable.
3. In the “Member Variables” tab of Class Wizard, locate the ID of your edit box control and click the “Add Variable” button.
4. In the pop-up dialog, enter the name of the variable you want to connect and select the variable type (such as CString or int).
5. 点击“OK”按钮，然后再次点击“OK”按钮以关闭Class Wizard。

Now, you have successfully linked a variable to the MFC edit box. You can use this variable in the program to retrieve or modify the text content in the edit box.
