Hi Yashodhan

>> But in the next line again it is not working. The code I wrote was -

DO FORM LookUp WITH THISFORM.Activecontrol.Name
WAIT THISFORM.Activecontrol.Name window

In the first command it passed the name. In second command it generated the error. I will really appreciate if you can tell me the exact concept of Activecontrol and how it works. <<

Ah. You did not tell me that you were trying to do something with the active control in another form < s >. In that case, you need this in the Init() of your Lookup Form:

LPARAMETERS toControl

You also need to add a property to your Lookup form called oControl to hold the object reference because, if you want it to be available to methods in the Lookup form other than the Init. If you do not save it to a form property, the reference will vanish when the init ends because it is scoped to the current method.

So the next line in your init would be something like this:

This.oControl = toControl

I am assuming, of course, that the calling form has actually verified that toControl is an object < s >.

You waould call Your LookUp form using an object reference:

IF TYPE( 'Thisform.ActiveControl.Name' ) = 'C'
 DO FORM Lookup WITH Thisform.ActiveControl
ENDIF

If you have put the code I have above in the Lookup form's Init, you should be able to put this line:

WAIT WINDOW 'toControl.Name is ' + toControl.Name

and get the name of the control that was passed to the lookup form.

HTH.
