How could i use the usercontrol to call the Window Form's Componet.

I create a user controls and added it on a Form.
There are also an textBox on the same Form.

But i can't assign an text string to the textBox on the Form by codding in the user control .

How could i do it.

Ther is many ways to do that , here i assumes that you will set a Button on your User Control , And you have a Textbox control on your main form

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim obj As New Object
obj = Me.FindForm
MessageBox.Show(obj.controls("TextBox1").text)

End Sub

Thats all

i don't know why you want to do that, but i could be done something like this:

' member variable in usercontrol

Private _HostedTextbox As TextBox

'property on the usercontrol

Public Property HostedTextBox() As TextBox

Get

Return Me._HostedTextbox

End Get

Set(ByVal value As TextBox)

Me._HostedTextbox = value

End Set

End Property

Then in the form designer-propertygrid you see in the usecontrol a property usercontrol
Set this property to the textbox you like, this could be any textbox on the form

in your usercontrol you could say now something like this

me.Hostedcontrol.text = "Tada!!"

As we know , very window form application has some buttons collection, like "Previous","next","first","last" and so on...

I want to make a usercontrol to re-usedable on very window Form .

I thouht that would be the best way to create application.
