accessing mdi child
-
Hi, i have 2 forms, frmtools and frmpad i have created 10 instances of frmpad and loaded them on mdi's load event now i want to do the operations only if the CurrentChild is any of the instances of frmpad. if the CurrentChild is frmtools then nothing should happen for that i have set the tag property of frmpad to "yes" and the tag property of frmtools to "no" and written the following: if Me.ActiveMDIChild.tag = "yes" then dim a as frmpad = me.ActiveMDIChild it works also. but, i don't know the use of tag property. will there be any problems due to the change of tag property or is there any other way to achieve this.

The tag property is just a place to put any piece of data you want. It's not used by anything in the .NET Framework. Think of it as a little box to put anything you want attached to that instance of the form. There are other ways of doing it, like seeing if the ActiveMdiChild is of a specific form type:
Dim currentForm As Form If TypeOf(currentForm) Is frmPad Then Dim padForm As frmPad = DirectCast(currentForm, frmPad) ... do whatever you need to do to the form ... End IfA guide to posting questions on CodeProject[^]
