Question

Using VB.Net

I have main form name as form1 and popup form name as form2

Form1

tab button – for creating mulitple copy of form1 at runtime…

Creation of mulitple from1 at runtime code

form1 code

Dim mEntryForm As form1
        mEntryForm = New form1
        mEntryForm.Show()

The above code is creating a same copy of form1 at runtime.

Now i want to pass the value from popup form to current activeform

Code for sending the value to form1 from popup form (form2)

form2code

form1.textbox1.text = "100"

The above code is going to form1 textbox, instead of active form (mentryform)

How to solve this problem.

Although I totaly agree with the comments about your question I ll try to give you a solution

Add a property to your Form2
name smtng like ActiveForm1 as form1

now because I haven’t understand completey your concept:

-> if Form2 is a ShowDialog form then you cannot change the active form1.
You need to set the property ActiveForm1

 dim frm2 as new form2
 frm2.ActiveForm1=me
 frm2.ShowDialog

->if Form2 is not a ShowDialog that means that you can change the active form1
then you need to add this lines of code when a form1 is activated

frm2.ActiveForm1=me 

Now in form2:

 me.ActiveForm1.textbox1.text = "100"

I hope that I helped you.
