I am creating a program that allows a person to enter details about their farm, stock, and machinery in order to electronically keep track of all of the information. I have created the forms and done all the coding for the data entry, and now what I would like to do is allow the user to delete a single record from the .dat file. I am able to delete it from the LstBox (using a "Delete Entry" btn coded simply with
lstvehicles.Items.RemoveAt(lstvehicles.SelectedIndex)
(using the vehicles section for examples)), but I am unsure of how to delete it from the .dat file as well, to prevent it reloading upon data change / program reload. Also I would like to be able to have a reminder come up on the program start up that gives a reminder to (in the vehicles instance)when a vehicles rego is due, the date being associated to a date that is entered into the same lstbox data using a datetimepicker.

I made a form that when you put your CustomerID in Text3 Box.. it access the records and make some calculations. now.. The customer will return the car.. Then his data should be deleted.. I want to know how to make that when I enter the CustomerID and press on the Command button .. It copies the other lines to a new output folder and doesn't copy these ... So it appears to be deleted using this way..
I was just wondering if there is a way to dim the screen and show a form which is not dimmed (eg. Vista/7 UAC prompts)? If so, how would i be able to it?

I have a project which contains reports and datasets. When I compile my project I don't want it to include the reports or datasets.So I can exclude them from the project. Fine.
But that also removes them from SourceControl, so then I have to check all my work back in. Which takes ages over my VPN.
Am I missing something here? Is there an 'exclude from compile' option somewhere?

I have an aspx page in VB that fills a pdf with data from a web form.I'm using iTextSharp for this and I have no problem with this.This is the second time I've created anything for pdf's and I'm using the code from the first script.The first script wrote the filled in pdf to a directory on the server where one person could access those via another aspx page.
