Problem running code stored on network yet works locally

[ALWilliams]

All,

I have been developing some vb .net 2008 code on my local machine and all has been fine.

I deceided to put the code on the network and off my local disk but every time I try and execute the code from this location I get a security error.

I have searched forums but cannot find a definitive answer as to how to solve this.

Any help much appreciated.

I have pasted the results below. This is a very simple app which only uses a list box and reads in a number of text files to count some stats.

Take a look at

Specifically 7 or 8 (I can't remember which one)

Your .Net needs to be told it can trust the "network residing" code.

I only have version 1.1 on my machine yet am developing in 3.5. Should there be a 3.5 framework configuration option or is it all the same?

 

[SgtJarrow]

Mine says Framework 2.0, but I am mostly developing in 3.5 I don't have one listed for 1.1 or 3.5

I think it is the same.....

I've done what the document says using 1.1 and still get the same error.

I've not run from a network share, but I don't see how it would be any different. If you are using framework 3.5 then it is going to require framework 3.5 on any computer trying to run the code.

It is installed on both. The issue here is when the code is stored on a network location and loaded onto my laptop and run from my laptop I get this error.

 

[Sorwen]

Ah, so you have 3.5 installed, but you are only getting the configuration for 1.1. I misunderstood what you had said. As far as I know you don't have to have the configuration. They only way I know of to get it is to install the sdk (2.0, 3.0, 3.5) on that computer.

This may end up just like what they said in the link, but the one time I did it and it worked I opened the config and just selected the Runtime Security Policy. Under there it has Tasks and one is Increase Assembly Trust. I just went through that. Like I said the end result may end up the same as the link, but I didn't go through any of the steps they said.

I relised last night that one of the first programs I did was actually on our network. hehe.

I'm downloading the SDK now so will feed back if I cant get it to work - thanks so far!

 

[ALWilliams]

I have installed this but I still no not have an option for framework 3.5!!

 

[pgordemer]

I just solved this problem here. Framework 3.0 and 3.5 are really using the base framework of 2.0.

I have a CAD application that gets updated constantly, so my desktoop shortcut for everyones computer runs it of a specific Drive/share on the network.

Here is a VB script snippet from my network login script that changes the policy

If objFSO.FileExists("C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\caspol.exe") Then
WSHShell.Run "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\caspol.exe -pp off -m -ag 1.2 -url file://w:/cad-std/* FullTrust", HideWindow, WaitonReturn
End If

 

[ALWilliams]

nice one - i solved it also myself by installing sdk 2.0 and applying full trust from there - cant believe the option wasnt in 3.5.
