Vb.net program check for updates

Here the only change that needs to be made is the error message at the end:. This is the class with the AutoUpdate function that checks if an update is needed. This can be directly copied to your code or can be in a library DLL.

If it's on your code, doesn't need to be a class. This function receives a parameter by reference, the command line passed to the program, and can be the original command line or the one passed by the Auto Update program. If it was sent by the Auto Update program, the Key will be cleaned from the command line, so you must use the returned parameter instead of the original command line.

Here you need to change the RemotePath variable to point to your update web folder and the error message at the end:. The auto update web folder should have a folder for each system you want to upgrade.
