問題描述

如下面寫的，把IDC_STATIC改名就可以了。

What error did you get?   What is the type of mLabel?  

First, right click on the static control and select 'Properties.'  If the control ID is IDC_STATIC you must edit it so it has a unique value, like IDC_MY_LABEL.

mLabel should be created by right clicking on the static control in the dialog editor and selecting 'Add Variable',  then selecting 'Control Variable'. The result will be a dialog member variable CStatic mLabel.  mLabel.SetWindowText should then work.
