But this is not what I get! I noticed only event number Hex "D" comming out when I shift between controls on the form. What is wrong here. MY problem is solved with event number 13 (D)

Many Thanks

Feldspar:

I was wrong ! In VS API veiwer displays message number 13 for WM_GETTEXT:
Public Const WM_GETTEXT = &HD

Actually I could have ellaborated more,

AS I told I want to perform a specific operation when any control on a window gets focus. The thing I am trying is in VB, I have created a custom windows procedure for one of my target forms. For every control placed on my current form I want to perform a common operation to all the controls, in form's custom windows procedure I have created. I want a kind of notification that every control generated to notify the main parent window (in my case when it gets focus). The control may lay on a picture box on the form or in a frame, but that event must be for "form window" so that I can handle as I have custom winProc only for main window.

The WM_SETFOCUS message is sent to a window after it has gained the keyboard focus. (I think this I am not looking for)

I want something like: The WM_XXX message is sent to main parent window of the window after it has gained the keyboard focus.

Any help wud be appreciated,
