I did update the schema of the dataset. In fact, when I tried to change the dataType in the designer it was already text.

I have a form which in effect is a launch pad for other forms.
When an option is clicked by the user, I wish to open a form associated with the option.
The problem I have, is that the opened form should remain on top of the main form, like an mdi child would remain on top of an mdi parent.
To achieve this, I have tried setting the TopMost property and the TopLevel property of the child form, which seemed to work until I drag a other application over my app, then the application will appear between the my parent form and my child form.
By the way, my parent form is NOT an MDI parent.
Any help on resolving this would be gratefully received.

An MDIChild form doesn't sit on top of an MDIParent. It's rendered inside an MDIClient control on the MDIParent form.
The TopMost property sets the form as the TopMost form system-wide, not application-wide.
You need the call the Show(IWin32Window) method of your second form to make it a application "TopMost" window. Something like this:
Dim newForm As New Form2()
newForm.Show(Me)

Did you try to simply lookup the entered Invoice number in the database and see what it returned??

I was used the data reader for checking the duplicate record, I want to check the InvoiceNo (Format is Inv/001/2008) is not duplicating in the database. I am already asign primary key to InvoiceId.
Please tell me what i do for checking the duplicate record.
Thanks in advance.

I already did. You don't use a DataReader to get all the records in the table and then search them. You write another query to the database looking for the entered invoice number. If it's there, meaning you get a record back from the database, you tell the user that the invoice already exists. If not, then it's a good invoice number. The SQL statement might look something like:
SELECT invoiceNumber FROM Invoices WHERE invoiceNumber = @userEnteredNumber

Why dont you add an index constrained to be unique to the 2nd column of the second databable in your database, then when trying to insert catch the error (duplicated key or violation of primary key (I dont remember the exact error)) but it should work

Sounds like you need to rethink your design. 2000 controls on a form ? You're kidding right ?

2 minutes with 2000 controls on a mobile device is freakingly fast, if you ask me.... 
|
|
|
|
|
The only way to make it faster is to rethink your design and GREATLY reduce the number of controls you're using on this form. 2,000 controls is just an insane number to put on a form. Creating a new instance of a control is a very expensive operation and there is simply no way to speed that up.

By using a third party component, or writing the code yourself.

I have written much code in VBA and now I wanted to explore Visual Basic 2005.
My objective is to be able to open an excel file and to plug in a value in range ("A1") in the excel worksheet/workbook from a Visual Basic 2005 form.
Any help/sample code would be tremendously appreciated.
Thank you,
Gray
