I am using this code below to delete files. Doing this permanintly deletes them, is it poseble to send them to the Resicle Bin instead?

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.

View 5 RepliesI know that Deleting a specific line in a sequential text file is impossible but instead copy the needed lines and not copying the unneeded ones to an output file .. killing the old one and renaming the new one with the same.. I can't make this step...
That is my record file
Code:
Input #1, CustomerName, CustomerHomeAddress, CustomerBussAddress, CustomerTel1, CustomerMob1, CustomerID, DateRent, CarRegPin
Code:
"Josek Sam","68 West Land Street","149 Union of States","4524563","45635463","JOSKSAM1",#2009-03-02#,"MILANCGLZ2008"
"Josef Malm","142 Unions Street","64 Hamersters Street","452504","42542054","JOSFMALM2",#2009-03-06#,"MILANCGLZ2008"
"Dave Green","131 Oxford Street","96 BlueBane Route","452542452","43254345","DAVGRN3",#2009-03-07#,"MILANCGLZ2008"
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 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. I wrote that code probably a year ago.Now, instead of having the filled in pdf sit on the sever, I have to email it, which I was successful at doing.The only issue left is to delete the filled in pdf from the directory.I tried to use file.delete(), but I got an error stating the the file was being used by another process.how to stop the process in order to be able to delete the file.[code]

This works fine when debuging i.e. it tries to delete the file and if not the error is caught and i can proccess it as nessecary, but when i build and run the app i get an error message telling me that the file cannot be deleted.
To test this code you will need a drive that can be physically set to read only (USB memory key, SD card) and try to delete a file on it while debuging and after a build.
Why would the same code run differently and how can i stop the excess error messages?
