Please be specific about what you mean getting tab pages from external files? Do you want to show the content of file inside a tab page when you open a file? :wtf: Dynamically you can add tabs to tab control. Lets get your answer and then see what i can do about it...

Oh.Yes. You'r right. I have a program that based on some tabs that those names and number obtain from db. You can think i wanna update my program and wanna just change some dll or everything that you think is possible. How i can change tab pages contents, i mean i wanna set each tab's page's contents from a .dll or something else. means how i can fill each tab's page with my favorite contents such as text boxes,labels and other activeX's.

First, I am sorry to say that your english is not good enough because I am confused by your posted messages. You can't add any textbox, label or etc. to tabpage in runtime but tab page to tabcontrol. You can simply place a textbox or a richtextbox inside a tabpage and then open the specific file and assign its content to that textbox. This sample code can give you some insight how to open a file and add it to richtextbox in tabpage. Scenerio: First, place a button on the form and OpenFileDialog control, place a richtextbox control inside the tab page and then place the code below for button's click procedure. Then run it and press the button. This sample works for only rtf. extensioned files. :wtf:

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

        OpenFileDialog1.Filter = "*.rtf|"
        OpenFileDialog1.RestoreDirectory = True
        OpenFileDialog1.ShowDialog()

        If OpenFileDialog1.ShowDialog() = DialogResult.OK Then
            RichTextBox1.LoadFile(OpenFileDialog1.FileName)
        End If

    End Sub

I'm not exactly sure if adding controls dynamically to the tabpage is required by the OP, but I just wanted to clarify that you certainly can add controls to a tabpage at runtime if required.

Tnx for you replies but my problem is diffrent. My main program have to have dinamic tabs which i want add tab pages to them. But i want that these tab pages exist in a external class object or every thing that is possible. Like a user defined control. You assume my program have a button that: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If myVar=0 then externalform.visible=true Else form2.visible=true End If End Sub and this externalform should be imports in header.Means i want to this form be a dll or every thing that is possible.Cause this form change every week. But i donno how i perform this.

Yes you are right! I made a mistake in adding it to tabcontrol not tab page. Dim myt as new textbox TabControl1.TabPages(0).Controls.Add(myt) is working... Thanks.
