[RESOLVED] Console app check for DLL

This is my first time designing a console app, and I'm having difficulty in getting this to work. I want it to check for my DLL in the same directory. If it's not there, the application should exit gracefully.

I thought this code would work but it still crashes without the DLL. Although it will not crash if I comment out everything after the IF statement.

Code:

---


Imports MyDLL.Test     
Module Module1
  Sub Main()
    If Not File.Exists("MyDLL.dll") Then
          Console.WriteLine("MyDLL.dll is missing")
          Console.ReadLine()
          Exit Sub
    End If

---

I don't see any code after the if block.

I left it off as it's all stuff using the dll. I was trying to get the application method to quit before it gets to that part if the dll isnt there

So you meant that you added a reference to "MyDLL.dll" in your project, but if the dll is not there, this will still run without throwing an exception?

Code:

---

Imports MyDLL.Test     
Module Module1
  Sub Main()
    If Not File.Exists("MyDLL.dll") Then
          Console.WriteLine("MyDLL.dll is missing")
          Console.ReadLine()
          Exit Sub
    End If
  End Sub
En Module

I'm pretty sure I haven't written this right. But ideally what I'd like is if the dll is not there, to just have the application say "Mydll.dll is missing" and exit after the user presses enter

Edit- And yes there is a reference to it in the project

As long as you don't have any code that uses the missing dll, your application will runs fine (it will work as shown in post#4 even if you added a reference to MyDLL.dll to the project and the dll is missing at run time). However, if you have just a single piece of code that uses the dll, even that code line never gets executed, you still get an exception. And that's why when you comment out the stuff below the if block it works.
To work around this, you will need to create a helper application that doesn't reference the dll and have that application as the startup exe. The helper will then check for the existence of the dll, and if it found the dll, it launches your main application. Otherwise, it displays a error message to the user.

Is it fully compiled and in a folder, like in Program Files or something?
Basically, how are you launching it? From the actual executable itself? From a shortcut link?

The program itself is just a single compiled exe. The bulk of the work is in the dll. For all practical purposes, the dll will always be there. But I want something that will tell the average user what went wrong in case I'm not there, should someone move it.

Is there a way to handle on the application level a FileNotFoundException?

The answer was much simplier than a helper application

Code:

---

Sub Main

    If Not File.Exists("MyDLL.dll") Then
      //Error code
    Else
        RestOfMain()
    End If

End Sub

Sub RestOfMain
  //My code
End Sub

oh duh...lol...
yh...u need an Else statement hahahahahaha
