Check control ID is 1191, in the child window in the TAB. The code is written in the create CPP, and then the code error directly.

This is an error

In the TAB that appears in a new problem, could not initialize?

The CWnd * into CTabCtrl *

You can't when you create the class you want to read the dialog content passed?
To read changes can also grasp the operation on the main window of notification messages, reading state again to your object,

An error now, but still and started the same.






I am in the main window created a TAB control, and then built a child window when the TAB on the first page, check1 is in the child window.

Because control is more, I read control using a for loop control ID, so each control so much trouble writing. Everything is normal, the Dialog window in a pointer to the CPP don't know how to build.

CodePudding user response:

CTabCtrl * pTab so can't convert CButton *

The CWnd * into CTabCtrl * because you know what is it

No see, how to write

CodePudding user response:

Getting the multilevel pointer is added in the Tab of the parent class or derived class a public function, then put these on the function, convenient call also simplifies the operation
In addition through AfxGetApp () - & gt; M_pMainWnd access class, need give AfxGetApp () - & gt; M_pMainWnd fu with normal pointer, you can use the APP wizard generates a dialog-based application, the MFC framework structure under study

CodePudding user response:

Can declare the control variables, but also more convenient across files or dialog operation,
