Partner error

Question

hey,

i am new robotics developer studio. i am having problem to start all the simulation tutorials and some in the ProMRDS. i keep getting error creating service and partner enumeration failure. i don't know what is the problem because i ran all of them successfully many times before.  but now i seem to have this error all the time. Some time i only got the dashboard but no simulator. 

I tried to reinstall ProMRDS but still no change. 

I'm using MRDS 4. window 7, 64 bit.

thank you.

A good way of diagnosing a problem like this is to use a local source control system to keep track of changes you've made.  Then if you break something you can look back to see what has changed to give you an idea of what may have gone wrong.  If you can't figure it out by reviewing the changes, you can use the source control system to revert to previous versions until you find the one that works and then find the exact change that broke things.

The two source control systems I'd recommend to help with this are Git or Mercurial.  Both of them have good Visual Studio support and Windows Explorer integration (via TortoiseGit and TortoiseHG).  Git in particular has a lot of community support and tooling around it so you can find articles like this one on using Git to debug like this.

Thank you.

Will look at it.

In fact I tried to reinstall MRDS 4 many times but still no change. I even reinstalled my Visual Studio 11 beta. But if i already reinstalled everything, does the source control system still apply?

Thanks in advance.

It's not going to help you recover from this situation, however the 'it used to work and now it doesn't what when wrong' scenario is all too common in writing software, so this is an important habit to develop.

If you want us to try and diagnose, we're going to need more information.  See this post as an example of a well written message with enough detail to try and figure things out.

Reinstalling beta builds of Visual Studio, which also has beta builds of the .NET Framework, tends to cause problems.  According to this post, Visual Studio 2012 final build is out today along with Windows 8.  I'd suggest reformatting your developer machine and installing the RTM bits, this is something I do whenever I've installed beta builds of Visual Studio or .NET Framework and the RTM comes out.  The good news is that we've had early access to these builds internally so I've just done this and Visual Studio 2012 installs *much* faster than Visual Studio 2008 or 2010.  Instead of it being an all day event, I was able to fresh install Windows 8 & Visual Studio in less than two hours.  If you don't have access to Windows 8 through something like MSDN, I'd still suggest you reinstall a clean copy of Windows 7 and then add Visual Studio 2012 Express.

Keeping all your personal files in cloud storage makes this reinstall easier.  For example, keeping your 'My Documents' in SkyDrive or Dropbox and your source code in GitHub or Codeplex (public) or BitBucket (private).

Sorry, 

i'm new to all this robotics software.

Here is my Dss Command Prompt error message. Hope you can help me tell what's wrong. 



Answer 5

Are your running the RDS 4 version of the ProMRDS code from http://promrds.codeplex.com/ or are you running an older release of the sample code?  It may be as simple as the sample code you are running is incompatible with the version of RDS you have installed.
