View 2 Repliesvs 2010, vb.net My program uses clickonce to automatically check my website for an updated publish, and then download and install if a newer version exists. I have been publishing my updates with the database excluded because if I include it, it overwrites the user's existing database with a new empty database.
My issue is that the new version of my software needs to have additional columns added to the existing database so that the user can save additional information. For example, the previous database table allowed saving client first name and last name, but the new version needs to have a new column for "address".
Is there a way for me to add a permanent database table or add a column to the user's existing database table without overwriting their current data?

I 'd like to enable the user to apply a custom filter to a System.Data.DataTable.At the moment I have a very simple function like this:
Dim result = dataTable.Select(txtUserInput.Text)
With the filtered results I'd like to do further operations(e.g. Database Update/Delete).Is an sql injection protection needed or is the "Select" function secure?
//Edit:Can the "select" function be abused to manipulate any data in the datatable, execute code, ...? If the only danger is that this function can return to much/to less data there is no problem. But if the data in the dataset gets corrupted it's a real problem.

Since i update my program a lot i want to implement a update system into it And im new to programming, so i would prefer it to be a very simple system.. What i want it to do is, when a user presses a update button it should check on a specific ftp server if the file version is newer than the one the user is having. If it is then it should just download it from the ftp server and then replace the original exe ..

i want to create a system update..When the user clicks on this button will check if a newer version If so, it will ask if it OK to download and approve it will download the file and open it right when the download is complete?
View 10 RepliesI have a program that I have gotten as far as programming it to inform the user of updates, have them push a button to download it. The updated version of the exe will be downloaded into a subfolder called "Updates", where there is a program called "Updater.exe"This program is one form, with a progress bar and informs the user the program is being updated. Every time I run through it step by step it appears to work, but in a real environment the program stalls out. It doesn't crash, but the bar continues to move with no action being taken. I can not help but wonder what on earth must be going on in the code, which you can see is quite sloppy and rather unweildy:[code]And there is of course the issue of not being able to change data on the hard drive without administrator privileges as is being discussed here: url... When I finally get a manifest working for this program to require administrator access....how could that screw up this updating process...How can I better perform this, what seems to me, simple process of deleting the old file and replacing it with the update?

I have Visual Studio 2008 Pro. First of all, I realize that an executable gets placed in the bin directory, but I don't want to go there everytime I build by project. Also, building doesn't seem to increase the version number. I want to be able to use the publisher, which increases the version number, but I want to only end up with a single file, an executable. I also want it to be able to check for updates.
