Setting Version and Date Information - Syntax help needed.

Friends,

I have the following code:

Imports System.IO.FileInfo

Public Class VersionInformation
Inherits System.Windows.Forms.Form

Private Sub Label4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label4.Click

End Sub

Private Sub VersionInformation_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim myAssemblyPath As String
Dim a As Reflection.Assembly = _
System.Reflection.Assembly.GetExecutingAssembly()
myAssemblyPath = _
a.Location.Substring(0, InStrRev(a.Location, "\"))

Dim fileInfo = new FileInfo(Assembly.GetExecutingAssembly().Location ) <--------- I'm getting an error, Assembly - Expression expected

lblVersion.Text= System.Diagnostics.FileVersionInfo.GetVersionInfo(Assembly.GetExecutingAssembly().Location) <--------- I'm getting an error, Assembly - Expression expected
lblDate.text = <---------- What does I need to put here to get the Date Modified?
End Sub
End Class

This code was given to me by another poster, but I'm not sure how to tie it all together, and I'm in a hurry for a response.

Thanks in advance!
Best Regards,
Eric

Assembly.GetExecutingAssembly().Location can return different types of values depending on whether the assembly is in the GAC or not, etc.

What is the actual value returned by "Assembly.GetExecutingAssembly().Location" when the error occurs?

??? I can't tell you that, because this won't even compile as it is. By the way, what is GAC?

YZlat

GAC is Global Assembly Cache. If more than one application on your machine is using the same component, you can palce that component to GAC

YZlat

one of the benefits of doing that is that if you make a change to that component, you won't need to go into every application that uses the component and replace the local copy with an updated version. Using GAC saves you from "DLL Hell" we had in VB6

From what is described here: I don't think I have multiple apps using this component. This all seems very complicated (compounded by my stupidity)

This form is a part of a simple exe. Is there an easier way to find out the file version and date of the exe so that I can display them in an about form?

Justin,

Yeah, sorry I didn't specify the type of error earlier.

It's now giving me another compliation error:

Value of type 'System.Diagnostics.FileVersionInfo' cannot be converted to 'String'.

Justin_W

lblVersion.Text = System.Diagnostics.FileVersionInfo.GetVersionInfo(System.Reflection.Assembly.GetExecutingAssembly().Location).ToString()

Justin,

You have gotten me closer than anyone else today, but this code gives me The exact path to the exe, not the file version number?

Am I driving you nuts yet?

Thanks,
Eric

Ah, I just realized, it actually gave me all the information. I didn't have a lbl box that was "tall enough"

I'm going to ask in another question a way to limit it to just the version number.

Thanks for your help!
