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. 
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.

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.

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<br />
<br />
If myVar=0 then<br />
externalform.visible=true<br />
Else<br />
form2.visible=true<br />
End If<br />
<br />
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.

You'll get plenty of spam from this, but no replies, I would think.
There are free and commercial libraries that do this, and there's a ton of info online about how to draw onto a bitmap in .NET.
But, if you have literally *no* idea, perhaps you need to learn a little more prior to tackling this project ?

Hello!
I am pretending to write a burner application in vb.net and I would like to know what api and/or com object I should use. Is there a sample code what could give me an insight how to do it.
Thank You.

I came across a project called XPBurn a while back - totally open source and free to use. The URL was:
http://www.gotdotnet.com/workspaces/workspace.aspx?id=2d7c26d1-8e05-4fd8-a868-cf794409a37e[^]
This component used IMAPI to talk to the burner, so by passed the XP Wizard for creating CD's. I did come across some issues using it (mainly talking to COM). I could never get the thing to work right (mainly because of time constraints), but did come across a project (can't remember the name) that someone created (not open source) that lets you burn a directory to a CD.
The other option is to hook into something like Nero (look on their site for SDK samples). There's a solution on their which is free, then their's another one which is not free (can't remember why one was free).

You musst be joking. This is not rentacoder. If you want to know how to do something, try to do it, and ask specific questions when you get stuck.

1: How can i get the name and path of opened document in word (I need to develop an Add-in for ms word)
2: I want to implement virus scanning in my email software how can i use any virus scanner to do this.
Thank you!

Answers:
1. it depend on how to open a document. If you have a openFileDialog control
use OpenFileDialog.FileName File name has both filename and path info
2. It depends on your virus scanning software. Some software can perform
virus checking for emails. For example Kaspersky is one of them.

I know how to take a Print Screen, but I want my program to do it, i.e. take a print screen every 5 minutes (using a Timer object). Is there any API function or something that I can use to do this?

I havn't tried taking a screenshot of the whole desktop, but try looking at the Win32 functions:
- gdi32.dll (function Bitblt)
- user32.dll (fuinction GetWindowDC).
I've tried taking a screenshot of a form before, in which case I needed to call the CreateGraphics method on a form.
You'll need to call GetWindowDC to get the device context of the form, then you'll need to use BitBlt to get the graphics data from the form into a Bitmap.
Try looking at this site:
http://mywiki.wikidot.com/forum/t-655[^]
It gives you more of an example of how todo this and could give you a direction on how to take a screenshot of the whole desktop.

Hello,
[2005]
I have filled a typed dataset.
I want to find the values of 2 columns (model, manufactuerer)
Where serialNo is = to something.
The serialNo is not the PK and is not unique. However, the model and manufacturer will always be the same for the specific serial No.
I could make a select query, but I don't see the need of making a call to the database when all the data is in the dataset.
I also have a bindingsource, not sure how can help,
Many thanks for any advice,
Steve

If you want to do this, first you need to get a DataView. That is done by taking the DefaultView off the Table you are looking at. So if you have a DataSet called ds.
You could set your dataview, we will call it
DataView dv = ds.Tables["yourtablename].DefaultView;
or in vb
dim dv as DataView = ds.Tables("yourtablename").DefaultView
Then with your dataview you can set the RowFilter.
so something like dv.RowFilter = "ColumnName = 'value'"
Where you replace with the correct ColumnName and the correct value you are looking for.
Once the RowFilter is set you can access the DataView rows with a for each loop or however you choose to look at those records.
Hope that helps.
Ben

basically i want a database driven dynamic menu as a set of link buttons
for that i ve used a placeholder control
now i m able to add link buttons dynamically
but unbale to track their click(OnClick) event
|

For any dynamically created control, you have to wire up the events yourself. But, this is an ASP.NET app. I seem to remember something about an OnBubbleEvent?? I can't remember, since I don't do very much ASP.NET development. You might want to ask this in the ASP.NET Forum.
