I have searched lots of way to make a 30 day trial limit of my program. They say "Use -Settings- in visual basic application for your variables" to save the information about user (like : registered or not registered or when the program expire). (You can see the 'Settings' when you double-click on "my project" in "solution explorer") Does the data which we use with "settings" saved in our program or somewhere in the computer?

I have written a small program in VB 2010 Express and I would like to show the version number of my program on the form. I looked through the HELP files and found an example. I put the example in my code like this:'Get the version of the current application.
Dim assem As Assembly = Assembly.GetExecutingAssembly()
Dim assemName As AssemblyName = assem.GetName()
Dim ver As Version = assemName.Version
Me.Text = "1st CPC Check Deposit Program Version" & " " & ver.ToString
I am up to version 1.0.0.8 but this is what prints:
1st CPC Check Deposit Program Version 1.0.0.0
Why doesn't it print 1.0.0.8 ?

View 2 RepliesI wrote a programme and sent it to my client, (it was not a deployment or install file - just the .exe). He responded that it would not run and the PC reported "this program requires Net Framework 2.0". He cannot update the PC in question with Net Framework 2.0. So my question is can i somehow change my program to use an earlier version of Net Framework?
View 11 RepliesI have several programs written in VB2008 on a network shared drive. Multiple PC's which have access to this drive run the programs. The problem is when I want to upgrade the program or a file/picture with changes, either I cannot overwrite the .exe file because someone is running it, or for example, a background picture on an open form is loaded and then I cannot change the picture on the server. I thought of placing a timing loop in the programs to frequently check a file on the server, which when I need to make a change, I can fill with an appropriate trigger word (like "exit") that would have the program terminate and be unable to restart until I change the file to "OK", but this seems rather crude. I assume there's a better and more elegant method.
