I am trying to add and remove controls dynamically in VB6
I could add it by using Controls.Add
But when I try to remove the control using Controls.Remove, I get the following error:
Unable to unload within this context (Error 365)
Any help on this will greatly be appreciated!!!

Where do you try this (which event) ... ?

Because, in some cases, you can't do it, ...

Maybe this Microsoft-Article helps:

Thanks for the prompt answer but I had already gone through that aritcle

This happens in the click event of a combo control.

I had also commented the Unload statements but it didnt help.
When I create the controls dynamically, I had given a prefix of dyn for the names.
I am able to set the visible property of the control but can't remove it.

                For Each x In Controls
                    If Left(x.name, 3) = "dyn" Then
                        Controls.Remove x
                        'x.Visible = False
                    End If
                Next

When it reaches the statement,  Controls.Remove x, the errror "Unable to unload within this context" pops up.

Is there anyother way in which I can remove the controls??

It is essential I remove it and since I added them using the Controls.Add method I have to use the Controls.Remove method to remove it!

Thanks in advance for the help.

Try this ...

Replace this line
Controls.Remove x

with this line
Controls.Remove x.Name

Hope this helps

In the click event of your combo control, start (or enabled) a timer. In the timer event, put your code to remove the dynamic controls.

Thank you wsteegmans and emoreau for the answers.
The timer thingy did the trick.
I can now remove the controls at run time
