in visual basic using a button but i cant get it to work since there's a lot of conflicting stuff in that command and visual studio gets confused.

here is my code

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
  Dim strGreeting As String
  Dim strName As String
  strName = TextBox1.Text
  strGreeting = "Hello " & strName
  MessageBox.Show(strGreeting)

    This doesn't show us the errors or the code you have. Update your question. – LarsTech Mar 15 '20 at 17:05
  • Would it perhaps be simpler to set a CLASSPATH environment variable for the process you launch? https://stackoverflow.com/questions/14553830/set-environment-variables-for-a-process – Caius Jard Mar 15 '20 at 17:07
  • I added my code. – Union Memeory Server Mar 15 '20 at 17:11

    Yeah, you kinda need to put those arguments INSIDE a string. Visual Studio is "getting confused" because all that argument string has been pasted in without `" "` so it thinks it's VB.NET (and it's not) – Caius Jard Mar 15 '20 at 17:12

Perhaps like:
