I need some help regarding the creation of control instances during runtime of an application. For eg: I have a tabcontrol with only one tab, and a textbox in that single tab. When I click a 'NEW' button, a new tab must be created in the control AND along with that I want a new text box in the latest tab. I am using VB
Thnx for any help...

The textbox needs to be added to the tab control's controls collection, and the tab page is added to the tab controls collection of tab pages.

Hello Christian,
Thnx for your suggestion. But can you explain it? I understood what you said, but still didnt get how to do it. I hope you have not forgotten that I'm using VB.

Add the control you created to the forms Controls collection:
Dim tb As New TextBox
tb.Location = ...
tb.Size = ...
Me.Controls.Add(tb)
For the tab page, you add it to the TabControl's Controls collection.

Adding an control at runtime
The following routine adds the Email label and associated text box at run time.
Private Sub AddEmailAddress()
Dim txtEmail As New TextBox
Dim lblEmail As New Label
' Set the desired properties
txtEmail.Top = txtAddress.Top + txtAddress.Height + 10
txtEmail.Left = txtAddress.Left
lblEmail.Text = "Email"
lblEmail.Location = New Point(lblAddress.Location.X, _
txtEmail.Location.Y)
' Add to the collection
txtAddress.Controls.Add(txtEmail)
txtAddress.Controls.Add(lblEmail)
End Sub
The above is adopted from MSDN. When you are creating controls at runtime you need to add event handlers in runtime also..

I need to slove my problem in VB.NET not in C#

The article supplied contains a library that will create a proper datasource from a multi-dimensional array. Just download the .dll and add a reference to it. You can then use it like this:
Dim test(2, 2) As String
test(0, 1) = "SomeData"
test(0, 2) = "SomeOtherData"
DataGridView1.DataSource = New Mommo.Data.ArrayDataView(test)

Thanks a lot!! It worked well for me.

I have given the Idea with the help of that article.
I cannot do your work.
Please do the work and if there is any problem we can guide you.

The code is easily convetible to VB.NET.
If you want a translation guide, all you have to do is look in the documentation on MSDN. Nearly every single code sample for any class, method, or property, comes written in VB.NET and C#. All you have to do is compare the two to learn the syntax.

Am using a tabcontrol for an app. 1 of these tab pages contains code which needs to be executed but not before that particular tab page is fully visible. Problem I'm facing now is that this code (which is in the Enter event of that tab page) is executed basically inbetween switching from tab1 to tab2. Is there a way to check if a tabpage or a particular control is really visible on screen?

It has a Visible property, is this not working as you'd hope ?

No, the Visible property already results to "True" even if the tabpage hasn't been complete finished displaying.

Why is that?
It sounds like it has something to do with the actual display of the tab page, and in that case it should be done in a Paint event. There might be other windows partly covering your window, so even if the tab page is visible, it might not be fully visible, and if you don't handle this in a Paint event, you don't know which parts are visible.

The 2nd tabpage contains some code which takes a bit of time. I want that tabpage displayed completely before that code starts. This tabpage contains information for the user of "how / what" is happening. There is no overlap of any other controls.
Let's say this tab page contains a label called "lblUserinfo" which contains a bit of informative text for the end user. I want the code not to start before that label is actually being displayed.

I don't like doing this, but have you tried sticking a Application.DoEvents() at the beginning of your "long running" code?
Normally, I'd be running all the code to setup the controls of every tab of a tabcontrol before I let the user see it. You treat all the tabs of a tabcontrol as a single control and not on a per-tab basis.
For instance, an options dialog with multiple tab pages gets and sets the values for all the controls on every tab page when the dialog is shown, NOT when each tab is shown. When the changes are done being made, the dialog writes all the values, on every tab page, back to persisted storgage and applies all the changes to running code when the dialog is dismissed. It doesn't do this when changing tab pages.

Controls are created prior to running the code. I'm just wondering if there is a way to actually check if a control is visible to the user. Just using control.visible() will result in True but that doesn't mean the user already sees the control.

No, there isn't.

Hey:
I want to pass two dimensional array in my function and return one dimensional array. My function will take two parameters:
1. two dimensional array
2. Row number.
Once I call this function, it should return me one dimensional array i.e the row.
For example,
Dim data(2,2) as Double<br />
Dim row as integer<br />
Dim tempRow(2) as Double<br />
<br />
row=0<br />
tempRow=returnRow(data,row)
When I called this function, it should return me the first row since row is 0
Can you please me how to pass the multidimensional array and return one-dimensional array back.
