Creating Repeated Controls :
----------------------------
1.Place a PANEL Control Class , Two BUTTON and Two LABEL on Form.
2.Set the AUTOSCROLL property of PANNEL is TRUE.
3.Write the following code within a FORM as follows…
'--- BEGINS
Dim txt As TextBox
Private Sub Button2_Click(…) Handles Button2.Click
Dim a, y As Integer
y = 10
Panel1.Controls.Clear()
For a = 1 To CInt(TextBox1.Text)
txt = New TextBox()
Dim Lbl As New Label()
Txt.Location = New Point(20, y)
Lbl.Location = New Point(2, y + 3)
Txt.Width = 75
Lbl.Width = 25
AddHandler txt.Enter, AddressOf CursorGotFocus
Panel1.Controls.Add(Txt)
Panel1.Controls.Add(Lbl)
txt.Tag = a
Lbl.Text = a
y += Txt.Height + 5
Next
End Sub
Private Sub CursorGotFocus(ByVal sender As Object, ByVal e As System.EventArgs)
Dim C As Control = sender
Label2.Text = "Cursor On " & C.Tag & " TextBox....! "
End Sub
Private Sub Button1_Click(…) Handles Button1.Click
Dim T As Control
Dim Result As String
For Each T In Panel1.Controls
If TypeOf T Is TextBox Then
Result &= T.Tag & "." & T.Text & vbCrLf
End If
Next
MsgBox(Result, MsgBoxStyle.Information, "")

Sounds like your trying to get around a copy protection scheme. You're not going to get any help with that.

Hi All,
Is there a way to add (or map) directly from dataset to combobox? I tried to use ComboBox.DataSource = ADataSet, but it doesn't seem to work. The reason that i'm using dataset to map direct to combobox because the data in the database is huge. It's about 20,000 records; and I don't want to use for loop or while loop to loop through and add one by one. If anyone know a way to do it, please help me.
Thank you for helping.
John

In addition to set DataSource, you have to set DataTextField, DataValueField also. If the DataSet has more than one table you to set the DataMember property also.

Urgent - HELP!!!!!!!!!!!!!!
How do I populate three (3) different listboxes in a single form - programmatically (vb.net)? I really do not want to use the visual tools.
The items of the listboxes are coming from the database. I can connect to the database and can query the database to the specific tables, but my dilemma is that I can't seem to populate the listboxes.
Do I need to instantiate three different sqladapters and datasets after I connect to the database? Afterwards, how do I map or bind the results to the specific controls. Please provide a simple code.
Thanks.

I'm working on a project Visual Studio and in my
project, I am not able to use .NET dialog boxes (ie. MessageBox.Show,
OpenFileDialog, etc.). I have to use the dialog box code from VB6.
Why is this happening and how can I fix it?

Messagebox and openfiledialog are in the System.Windows.Forms namespace. Make sure it is referenced/imported etc... properly.
The openfiledialog is a control from the toolbox that you could drag onto your form or
Sample from Help
Dim myStream As Stream<br />
Dim openFileDialog1 As New OpenFileDialog()<br />
<br />
openFileDialog1.InitialDirectory = "c:\"<br />
openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*"<br />
openFileDialog1.FilterIndex = 2<br />
openFileDialog1.RestoreDirectory = True<br />
<br />
If openFileDialog1.ShowDialog() = DialogResult.OK Then<br />
myStream = openFileDialog1.OpenFile()<br />
If Not (myStream Is Nothing) Then<br />
' Insert code to read the stream here.<br />
myStream.Close()<br />
End If<br />
End If<br />

I checked what was imported in the project properties and it is show Microsoft.VisualBasic. When I removed this, all of the places where I have had to insert MsgBox became an error. Perfect, but then when I try to replace MsgBox, MessageBox is not recognized. What do I have to Import into the project properties?

Forget about msgbox. Use MessageBox
In the project references make sure that System.windows.forms is referenced else add it.

Hi,
My form have a datagrid from ArrayList.
I would like to modify some cells of values using "edit-in-place".
After I press keyup, the new cell value is canceled and show that message: "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: Index Do you want to correct the value ?"
How can I modify a cell value using "edit-in-place" on Datagrid ?
Thanks.

Hi! I have a main form that handles several other child forms.The thing is that when i close the main form, and i want to close all of the child forms, it seems that the Main thread doesn't wait for the child forms to terminate.The main form calls Dispose() which destroys the mainUI first than the childs. Is this the correct procedure or do i have to destroy first the child forms and only then the mainUI?
Thanks in advance.
Never say never

Hi,
I have a Map system (mentioned in the object) that in VB6 is addressed that way:
private mpview as IMapView (an interface)
mpview=axmap.object (where axmap is the control on the form)
The problem with VB.NET is that I don't have the .object property. And if I simply try mpview=axmap I get an invalid cast....
Any idea how to work it around?
Thanks
Briga

A better bet would be to ask the manufacturer of the control what the correct procedure is for VB.NET. You'll find a very small user base, if any at all, for people with experience with this control.

If the manufacturer of the VB6 OCX cannot provide you with the NET Interop assemblies needed to use the VB6 OCX in .NET, then what you will have to do is put the Map control in a VB6 UserControl that provides all wrapper functions you need to interact with the child Map control from your NET application. Then you should be able to import the UserControl you created into VB.NET.
You should review your licensing agreement. Most commercial VB6 OCX controls prohibit reverse engineering, and wrapping in another OCX for purposes of redistribution to other developers. Wrapping a 3rd party OCX in your own custom control OCX for use in your own applications is rarely a violation. But you should still check.
