ListBox is one of those Controls that offer an Items collection, which you can
use and abuse at all times.

I have managed to change the TabPage Color but I don't know how to change the background color of TabControl. I tried to put following code in Form paint event but still I coudn't remove the grey color of Tab Control.
For Each ctr As Control In frm.Controls
If TypeOf ctr Is TabControl Then
Dim rect1 As New Rectangle(ctr.Location.X, ctr.Location.Y, ctr.Width, ctr.Height)
Dim brush As New SolidBrush(Color.Green)
grph.FillRectangle(brush, rect1)
End If
Next
I would appreciate for your help.

There is no such direct way of setting backcolor property of Tab Control. However after setting DrawMode property of tab control to OwnerDrawFixed, we may draw tab control using our custom code.
Put following line of code on form load event –
Me.TabControl1.DrawMode = TabDrawMode.OwnerDrawFixed
Put following code in DrawItem event of Tab control-
----------------------Code Start---------------
Private Sub TabControl1_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles TabControl1.DrawItem
Dim f As Font
Dim backBrush As Brush
Dim foreBrush As Brush
If e.Index = Me.TabControl1.SelectedIndex Then
'''''If its the tab page which is selected
f = New Font(e.Font, FontStyle.Regular)
backBrush = New System.Drawing.Drawing2D.LinearGradientBrush(e.Bounds, Color.AntiqueWhite, Color.LightSkyBlue, System.Drawing.Drawing2D.LinearGradientMode.Vertical)
foreBrush = Brushes.Black
Else
'brush for unselect tab pages
f = e.Font
backBrush = New SolidBrush(e.BackColor)
foreBrush = New SolidBrush(e.ForeColor)
End If
Dim tabName As String = Me.TabControl1.TabPages(e.Index).Text
Dim sf As New StringFormat
sf.Alignment = StringAlignment.Center
''''Draw tab rectangle
e.Graphics.FillRectangle(backBrush, e.Bounds)
Dim r As RectangleF = New RectangleF(e.Bounds.X, e.Bounds.Y + 4, e.Bounds.Width, e.Bounds.Height - 4)
'Draw text of tab pages
e.Graphics.DrawString(tabName, f, foreBrush, r, sf)
sf.Dispose()
If e.Index = Me.TabControl1.SelectedIndex Then
f.Dispose()
backBrush.Dispose()
Else
backBrush.Dispose()
foreBrush.Dispose()
End If
End Sub
---------------------Code End---------------
I hope this helps.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitdebugging="true">
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
I hope someone can help me.
I've been looking on the internet for this week and can't find any thing that should help me.

Hi Man
Is the Computer of the Client has .NET installed ?
Try to Install Microsoft Data Access Components 2.7 on that Computer, i have been using Access as my back-end but i have never came across a Problem.
Hope it helps

Hi.
Sorry to say but that was not the solution.
I've installed MDAC 2.7 and still I'm getting the same error.
The most frustrating about this all is that the error message says that there is no message.
<br />
System.Data.OleDb.OleDbException: No error message available, result code: -2147024770(0x8007007E).<br />
I expect that if something goes wrong VB lets me know WHAT goes wrong.
Hope you got some more info and an solution.
Thanks a lot.

It appears to be bombing out making a connection to the database, so I'd probably start looking at the connection string. Maybe the setup put the database where your code isn't looking?

I don't understand what you mean by 'It appears to be bombing out making a connection to the database,'.
That kind of English is an bit to difficult for me.
I'm dutch.
Maybe you got an bit of code to show me what you mean.
My App.Config looks like this:
<
connectionStrings>
<add name="Access_DB_2.My.MySettings.TestDatabaseConnectionString"
connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\Data\TestDatabase.mdb;Persist Security Info=True"
providerName="System.Data.OleDb" />
</connectionStrings>
>
I also thought that would be an problem so i changed my VB code on the load event to this:
<br />
Dim oDa As New OleDb.OleDbDataAdapter("SELECT * FROM tNamen", "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\Data\TestDatabase.mdb;Persist Security Info=True")<br />
Dim oDt As New DataTable<br />
Dim oBs As New BindingSource<br />
<br />
oDa.Fill(oDt)<br />
oBs.DataSource = oDt<br />
<br />
Try<br />
DataGridView1.DataSource = oBs<br />
<br />
Catch ex As OleDbException<br />
MsgBox(ex.Message)<br />
Catch ex As Exception<br />
MsgBox(ex.Message)<br />
Finally<br />
oDa = Nothing<br />
End Try<br />
But that was not an solution.
The directory my Program is installed in is: c:\program files\EwR Development\Access DB 2.
And the database is in: c:\program files\EwR Development\Access DB 2\data
The images are located in: c:\program files\EwR Development\Access DB 2\Images
If you need my project I'll send it to you in an zip/rar file.
If you need de setup i can send it to you to. Also in an zip or rar file.

If the code runs in the debugger, I'd check to see if your installation actually did put the database in the correct folder under Program Files. If it's there, open it up in Access and make sure it has the same schema you expect it to have.

Finally my problem is gone.
On the target PC I've made an new install of Windows XP and everything works fine now.
I was so tired of everything going wrong and had done so many thinks trying to make it work that i didn't see any other solution.
And it works.
Looks like my target PC was too full of sh*t and couldn't work any more.
Thanks for your help anyway.

When a multithreaded application hits a breakpoint do all threads stop or just the one that hit the breakpoint? If the first one is true then what happens to the other threads when you step through your code?

 I am building an application using two forms. On form1 I have a list box, and two text boxes, one for a string and the other for an integer.
Form2 has two text boxes and a button. When the button is clicked, I would like the data (string and integer) diplayed in the textboxes on form2 to be displayed in the listbox on form1.Also when the item is selected in the listbox, I would like the string and integer to be displayed in the relevant textboxes on form1.
Please help..

With what? You haven't provided any code. Or are you expecting someone to do your work for you?
Read the MSDN documentation to learn about the properties and methods exposed by the textbox and listbox controls. Attempt to solve the problem yourself and post again if you have more specific questions.

I have two forms. One is used to add data and the other to view that data.
The first form is used to add items to a listbox (on the first form). How can those items be added to the second form, so that they are available in the combo listbox on the second form?

You need to set your code to use an Indian locale. By defualt, your application will use US culture settings. The following example example produces the desired results using the Hindi (India) locale.
Thread.CurrentThread.CurrentCulture = New CultureInfo("hi-IN")
Dim d As Double = 1213456.05
Console.WriteLine(d.ToString("N"))
A full list of the available cultures can be found here[^]

Hi,
I have taken an example from MSDN.
Public Function GetSchemaTable(ByVal connectionString As String) _
As DataTable
Using connection As New OleDbConnection(connectionString)
connection.Open()
Dim schemaTable As DataTable = _
connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, _
New Object() {Nothing, Nothing, Nothing, "TABLE"})
Return schemaTable
End Using
End Function
I have called this function in my code on MS Access DB Connection String, and got DataTable object in return but I'm unable to find table names in DataTable object, can anyone please help me in that, what am I doing wrong.
