DoDataExchange()?

Can anyone help?

First, let class wizard populate most of the code for DoDataExchange.
Hover over your DLG resource, and right click on one of your dlg items and select class wizard. This will bring up class wizard with the dialog/dlg item as the focus. On the second page of property sheet named "member variables", give each control id a member variable.

Now class wizard has populated most of the data for DoDataExchange.
When ever you make a change to each dlg item, that item will save it''s data in the member variable for that item.

For the second part, you have many options.
I suggest double clicking dlg item on the left to allow class wizard to add message handlers.
In each of these add code to set the text for the appropriate item on the right.
e.g.
SetDlgItemText(IDC_TKT_FAX_DEPT_BILL_CODE,m_DFX_Dept_Bill_Code);
where the first item is the dlg item you want to change and the second is the variable that holds the data you want.

That''s a quick summary.

Thanks for the help!

I think there is an even easier way. Maybe a slight bit slower, but less code. When you are making your dialog resource, hold down ctrl and double-click the control. It will come up with a fancy little dialog to add a member variable that synchs with the control. I think you already know how to do that part. Now, in your code, just call UpdateData() to get all the info in the dialog loaded into the variables, then edit the variables, call UpdateData(FALSE) to load them back into the dialog.

If you change a variable which is associated with a control, you can call UpdateData(FALSE) to update all controls with the data in the variables. Calling UpdateData(TRUE) takes the data in the controls and copies it to the variables that are associated with them.
