I've almost finished my database application, and I had an idea to insert a button that creates a copy of the database. However, when I click the button, it destroys all of the data in the file before copying. It's a 2000 .mdb Access file with 500+ rows so far.
Here's the code that handles the backup: Private Sub btnBackup_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnBackup.Click

View 3 RepliesI've got an app which uses a background worker to copy files. It works fine but some files are quite large and it "appears" as though the app isn't doing anything. Is there an alternative to the File.Copy method of copying files so I can report on the progress of individual file copies, like the percentage complete?

I'm using "My.Computer.FileSystem.CopyDirectory(...)" to copy large directories (30-50gb) from one mapped share folder to another. Using "FileInfo.length" to add up all file and subfolder sizes, determines the 'origin directory' size just fine. However, if I use the same method for determining the size of the 'destination directory', mid copy, it returns the full file size, despite the copy not yet being complete.I'm at a loss as to why, as this method works fine in testing, going from a local PC t

I created a Right-Click Menu option for files. When the user clicks the menu option it will copy all of the file paths to the clipboard.The following function I have will retrieve all of the filepaths to the clipboard. The problem lies in adding the filepaths to the listbox. If I turn single instance application off the result is multiple instance of the application for each filepath. Say for example I selected 2 files and clicked my right-click menu, I wind up with 2 instance of my exe with each file path added to the listbox, 1 in one listbox, the other file path in the second instance listbox.
Public Sub getthepath()
Try
Dim thefilepath As String

Is there a way to loop through each file path from the clipboard and add them to the listbox through a loop?Several times I have tried different ideas I had that I thought would do it and I got odd results but never a good result.

I have written a program to add a timestamp to a data sheet which had the time in seconds at which a sample was taken. The sampling was done every 0.1 seconds i.e 10 Hz sampling rate.The code I wrote enables one to select a file to which the time stamp must be added, and then runs a macro from excel when you click "Add Timestamp".
I am having a problem destroying the objects though so that they don't end up hanging around in the background. If Excel is already open I do not want it to close at the end of the program, I want Excel to simply return to its state before the application was run in order to prevent losing data on another unrelated excel task which may be open. The macro which is called closes any sheets which it opens. The other problem I am having is that if the program encounters an error there are a number of Excel objects floating in the background. My code is posted below.

Hostmonster is linux-based, so the files won't copy without assigning an index page at the site.
