The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

Run Simple VB.Net EXE over network

Zones: .NET Framework 2.0, .NET, Microsoft Visual Basic.Net

Tags: VB .Net

OK, I am attaching a simple program I created in VB.NET, I can run this code from my desktop (XP Pro SP2) no problem, but if i place it on another machine in our network (XP Pro SP2) and run it from the command line (the networked machine is sharing a drive) from that machine I get a big error (see attached). I can run the exe on the other machine and it works fine...

Thanks for the help!!

if u copy the exe to the Local machine and then run it from there u will not find this error

.net security system has to be configured and Network access permissions have to be given according to the active directory and ur network topology...

simple solution is that copy the exe to the local machine may be deploy it using click once and start using it...

hmmm.... It is a simple permission issue if you are trying to run this over Network share...

You can change the .NET "Code Access Security Policy" to Full trusted on the other machine and it will work fine...

how to do that :
Control Panel>Administrative Tools>Microsoft .Net Framework x.x Configuration
Expand "my computer" and "Runtime Security Policy" in the right hand side choose "Adjust Zone Security" under tasks. In the security config box check "Make Changes to this Computer" and next, then select "Local Intranet" and change the security level to Full Trust.

hope it helps

StanicDejan:

There is a CASPOL command line utility included with .net runtime.

You'll find it in %WINDOWS%\Microsoft.NET\Framework\v2.0.507272\CasPol.exe (of course, substitute 2.0... for your version of .net). With this utility, you can easily adjust security.

For example, to allow full trust for .net applications running from youl LAN, you can issue the following command:

caspol -machine -chggroup LocalIntranet_Zone FullTrust

and your problem should go away.

Dejan

All,

I got it to work thanks!!!

Is there anyway I can catch this error with VB so that I can send a clearer email to the customer running the app??

02.12.2008 at 11:23AM PST, ID: 20877805

sporenza:

update,

ok so this worked on my first machine that had studio installed, but on another machine that had .Net 1.1 isntalled I had to upgrade to 2.0 (needed to to run the code) and then changed the internat settings to full trust but I still get the same error on this machine....

02.12.2008 at 12:03PM PST, ID: 20878243

StanicDejan:

If you used my way, you need to issue separate commands for each .net runtime, e.g. (example):

for .net 1.1: C:\Windows\Microsoft.NET\Framework\v1.1.4322\caspol.exe ...
for .net 2.0: C:\Windows\Microsoft.NET\Framework\v2.0.50727\caspol.exe ...

.net 3.0 and 3.5 use 2.0 runtimes, so there's no separate utility for them.

LP,
Dejan
