Double Insert In MS Access?

Apr 23, 2011

I'm somehow getting a double insert; every time I submit the form, it sends two records to the database. I can't figure out what's going on. This is a general idea of what my code looks like:Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click

'Data collection'
'Define Connection'
Dim myConn As New OleDbConnection

Create Custom Database In Windows Application - Double Click Custom Database File?

Jul 21, 2006

With VB.net, I'm coding a simple application to get more used to the new .Net format.

I'd like to save all the information to a 'new' database file. how to create a database on the fly, once that is done i'll be able to connect to it no problem, but actually creating the file is proving difficult to work/find out.

Also, with vb.net and the newly created custom file, how can it be made to automatically open that information with the program?

Is there a method in installation to associate the file type with the new program? How can i check when the program loads if a database file has been 'double-clicked' (rather than just running from the .exe of the program) and proceed to load the data?

EDIT1 - Extra InfoThe windows application has many different fields and content etc, then i need to save that to a file that could later be loaded by 'double clicking'. I assumed the easiest way would be to create a mini-database for each unique file

Flickering - Double Buffered Picturebox - Not Double Buffere - Black Screen With The White Lines

Nov 17, 2010

I have a htpc project that I am working on. The main program loads dll plugins which are basically other win forms. On each of these forms, including the main program, I use a picturebox (a double buffered picturebox) for the background image and then draw everything on it by hand. Whenever I load the form from the dll and show it, I get a weird flicker. It looks like it is the previously used double buffer. Is there any way to clear the background double buffer before the flicker? Or am I going in the wrong direction?

Here's a couple of videos of the problem:

Notice the black screen with the white lines on it or the flash of the desktop after I click "Movies." How do I get rid of that?

Dim dicDataSet As New DictionaryDataSet1()
[Code] .....

But unfortunately it doesn't run, when I debug, the code passed through all the lines without problem, but it doesn't insert the row in the DataTable. One curious thing is that when I run the application the database which remained connected It disconnects automatically, and I don't know why.
