Errors drawing

Postby Glyphi » Wed May 31, 2006 4:28 pm

I'm trying out your tracker, it throws an error whilst drawing:

SQL Dependency Tracker has encountered an unexpected condition.

The type in Assembly vjslib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a is not marked as serializable.

Can you help?

Drawing error

Hi there Glyphi,

Sorry for the delay in replying to you. We've been puzzling over this for a couple of days but it actually seems like the answer's fairly simple. The problem appears to be that you have the Visual J# Runtime for .NET framework 1.0, and the software is attempting to use that, which obviously won't work. What is more of interest is why this is happening.

First off, you need to be certain that you have the .NET framework 1.1 or 2.0 installed, although as far as I know SQL Dependency Tracker should not install at all unless one of these is already on the machine.

Now, it's possible that our installer may have incorrectly detected the version of vjslib that you have installed, and taken the presence of the 1.0 DLL as confirmation that you have the required library. At present we're not sure about this as we've not had a chance to test it.

The solution is fortunately fairly simple as well. You just need to download and install the Visual J# Redistributable that matches your installed .NET framework version from ... fault.aspx. If you have both .NET 1.1 and .NET 2.0 installed you should download the version for .NET 1.1 since SQL Dependency Tracker will run with .NET 1.1 by default and will not run if you have both versions of the framework but only the 2.0 J# distributable installed.

I'm sorry for the problems you've had with this. We're currently looking into why this has happened, and either myself or one of my colleagues will post up here again as soon as we have more information.

Kind regards,

Don't worry, as you can see It took me ages to spot your reply! The fix works - sadly my trial period has expired.

Many thanks, Glyn

Hey Glyn,

Under the circumstances, if you send me a private message I'll see about getting your trial extended if you'd like to continue evaluating the product.
