How to acess forms controls of one form from other in VB.NET Hi dk, The controls on Form by default declared as Private. Make it Public by
either using Modifiabilty property or in code window.
hope this helps.

How to acess forms controls of one form from other in VB.NET hi dk, unlike vb6, everything on forms is private, so expose anything you need
using a property. or, better yet, implement a function to write text to the
status bar and call it from the child forms... gives you better/cleaner
control over the form contents.

How to acess forms controls of one form from other in VB.NET Thanks dushan I wrote a public function (mdiMainStatusBarPanel) in mdiMain form. Indeerd it is a very good idea. I call it from the child forms. But for calling it I have to instintiate the mdiForm in child form Dim frmMdiMain As mdiMain = New mdiMain()
frmMdiMain.mdiMainStatusBarPanel(1, "Connection Successful")
It goes smooth but the value is not displayed on the mdi main form. I think
I should not instintiate it again. but I dont know how to refer the mdi form
in child form whiout declaring it again.
Some more help will get me through
thanks

How to acess forms controls of one form from other in VB.NET Thanks dushan I wrote a Public function (mdiMainStatusBarPanel) for changing the content of the status bar on mdi form. when I call it from the child form, it does not display on the mdi main form. Dim frmMdiMain As mdiMain = New mdiMain()
frmMdiMain.mdiMainStatusBarPanel(2, "Connection Successful")
I feel it is because, I am creating new instance of MDI main form here. I
dont knwo how to refer the old instance of MDI main form.
Pl help.
thanks

How to acess forms controls of one form from other in VB.NET Hi Yes, you are creating a new instance of MDI main form. You must get a MDI
main form reference. How ? In this especific case, you can use ParentForm
property of MDI child to get access to MDI main form. Try this:
CType (Me.ParentForm, mdiMain).mdiMainStatusBarPanel (2, "Connection
successful")
You can use ParentForm property because you are using MDI forms, and the
ParentForm of a MDI child form will be the MDI main form.

How to acess forms controls of one form from other in VB.NET Thanks. It worked fine. Still I want to know if there is any way to get reference of one form from (FORM 2) other form(FORM 1) without creating the new instance of the FORM 1. In my aplication MDI main form calls FORM 1 and FORM1 calls FORM2. I want to refer the controls of MDI Form and Form 1 when I am on Form 2. Thanks once again for the help.
regards

How to acess forms controls of one form from other in VB.NET dk, Why don't you create one global (project level) object for you mdi maon form
and use this everywhere you required. Since you need only one Mdi form and
that should be acceed from whoie applictaion.
Declare the public object of main mdi form in the startup.

How to acess forms controls of one form from other in VB.NET Ashok, Yes, but if this is needed, it is probably best to keep it encapsulated as a
Shared/Static property of the MDIForm.

How to acess forms controls of one form from other in VB.NET dk, using the parent property should work. or... what i do is create an
initialize function in all child forms, and pass it a reference to the
parent form. each child form then has a reference to its parent... even if
not mdi.
*** assuming you have a frmMain variable in the form module... remember NOT
to create a new frmMain; it'll hold a reference to the form
public function initialize(byref ParentForm as MyProject.frmMain)
Set mp_frmMain = ParentForm
end function
then
dim new_ChildForm as MyProject.ChildForm
new_ChildForm.Initialize(Me)
that oughta do it nicely...
