I have a VB 6 MDI application.
I can invoke help by pressing the F1 key providing an MDI child is displayed, help is not displayed if only the parent form is shown.
I have tried intercepting the keyboard, but this does not work on MDI parent forms.
Any ideas... thanks ...
You can add a toolbar to MDi parent, and a textbox (locked= true) to it.
Specifying your help file in project, and running it, when pressing F1 you will see your help shown as long as the textbox holds the focus.

Almost works. I have a toolbar that uses the imagelist to display buttons. I added the textbox at position -2000, so that it is not visible. Works fine first time, but if MDI child shown then closed, help no longer works, even if the textbox still has the focus. I have to switch to another app. and back for it to work. Using Text1.Setfocus (even though has focus) would solve the problem, but I don't want to do it this because
1. It would mean modifying all code to setfocus whenever no children or modal dialogs are shown/closed.
2. I have a number of apps. that would need changing.
I know using a Timer and setting focus if no other forms would work, but again I feel this is rather messy.
Any better ideas.
I agree. It would be easy if you add a button to the toolbar for displaing help with a click of the mouse. Unluckily Mdi forms Parent do not intercept keypressed...You may override this with a general keyboard hook, but for this you will need someone else help (ClearCode seems to know this issue well).
