Greetings,

I have a critical issue here and I want some help.

I have an open form "Form1" that contains a label "Label1" and I have another form "Form2" that contains a button "Button2". What I need to do is to get a reference to the opened instance of Form1 so that I can update the attributes of Label1 and also make it invisible through the Button2_Click event in Form2.

Is this possible or not in Vb,Net 2005?

Please advise,

Thanks in advance....

Solution 1

Yes possible you need to create an Object of Form1 in form2.
ex.

VB

dim objectname as form1

and access label1 of form1 in Form2.as
ex.

VB

objectname.label1.text="Text"

and make anything you want to Label1 in form1.

Thanks Guys,

I got the solution myself and I will show it here for anyone to get benefit of it.

We have here:

Form1 is opened
Form1 contain Label1
Form 2
Form2 contain Button2

Then at the Load event of Form1 we write the following code:

Dim pForm2 as New Form2
If pForm2.ShowDialog=OK then
Label1.Visible=False
End If

Please contact me for any further details,
