I have searched the forums and the question appears to have been asked many times, but never really answered, so I'll try again.

I have a CDialog-derived class, within which I need to scroll a portion of the dialog's contents. My particular case is that the dialog box size has to be fixed because of a low screen resolution on the target PC, but the contents are variable so a number of controls are added dynamically at run-time.

I have placed a vertical scrollbar control on the dialog resource, but I am having trouble making everything work together to allow the controls to be scrolled up and down without affecting the remaing area of the dialog (which contains OK and Cancel buttons in a fixed position).

Presumably I need to override OnVScroll, but what needs to go in it?

Couldn't you use a property sheet. The first set of controls on the first tab and the rest on the second?

Just a suggestion,

I'm adding a several rows of controls (check box, label, combobox and text box) which are related and need to be viewed together, so the PropertySheet approach wouldn't be ideal.

Would a grid control help? Or are the controls too different on each row?

The controls will be the same on each row, though the contents of the list in the combo may be different on a row-by-row basis).

I'm not sure if a grid control would give an interface that the user would feel at home with.

The approach I have currently uses a structure containing the checkbox, etc. which I create the relevant number of in a column and then adjust the text/list properties accordingly. I just want to be able to get at them all from a single, fixed size dialog by scrolling.

Have you tried having a set of fixed controls, say three rows. Then when the scroll bar is clicked, you replace the first row's data with the second rows, the second row gets the third rows data and the third row is blanked.

Way too confusing for the user I think. They are very basic, new to computers/windows users.

The data is generally configured as sets of four or six rows. If any extra rows are required, it is likely to be an extra four or six.

Can't you just have pop-up dialogs containing the additional controls. I think what you are trying to do is going to be REALLY hard. But then, I've never tried it.

The operating environment already has a cluttered desktop (the users have several other applications running at the same time) and so pop-up dialogs are not really a viable option.
