Why on earth do you have a "restart" button for "every new sale operation"? What does this mean?

OK, smartass, "restarting" your entire application after a sale is NOT NORMAL. I'm looking for an explanation as to why you think this is a necessary thing to do.

You can call Process.Start() with a parameter, e.g. "restart" and read the arguments in Program.Main(), something like this:

Dim p As New Process
p.StartInfo.FileName = "MyProgram.exe"
p.StartInfo.Arguments = "restart"
p.StartInfo.WindowStyle = mWindowStyle
p.Start()

could you explain please

Member 11903597 4-Jun-19 15:27pm

thank you, you inspired me to :
separate the login from the main application
and use process.start from the login form to run the main app
by that the login screen won't appear every restart

If it works I will no longer ask questions :)
