Greying-out contents of frames

[Nojj]

When you disable a frame by setting its enable property to false, the contents of the frame are disabled but not greyed out. Is there a way to grey them out without writing code to individually enable/disable every control in the frame?

As far as I know, you have to disable each control individually. However, that can be done quite easily by a separate subroutine which accepts a parent control id, and then loops through the controls collection, and processing only those controls whose parent is the passed in frame. Specific syntax will depend on what language you're using.

Thanks CajunCenturion. That sounds like a great idea. I'll give it a try.

One thing that you need to be careful of. If you have a frame inside of another frame, and you disable to outer frame, you will have a multi-level issue to deal with as the controls in the inner frame will have the inner frame as it's container, and not the outer frame.

As long as you don't have container objects inside of the outer frame, you don't need to worry about it.

Here's the code I tried which works OK for most controls but it fails when I put a SysInfo control on the form. Why?

Dim objCtl As Object
For Each objCtl In Controls
If objCtl.Container.Name = MyFrame Then
objCtl.Enabled = False
End If
Next

The SysInfo control has is a special purpose control and may not have an enabled property.

There are two ways to deal with this. One way is to take the SysInfo control outside of the frame so that its containiner is the form. Second, you could use the on error resume next statement, to ignore the error.

The error occurs if the SysInfo control is inside or outside the frame. I added this line to avoid it.

If TypeOf objCtl Is SysInfo Then

Everything works fine now. Thanks for your help.
