Is there a Named Expression to check for a specific sheet name?

Hi Regan,

I found some free time and updated a project I played with a few years ago. A resuilt is an attached symbol provider library with the required functionality:

Please be aware it's a freeware without any warranty or support provided.

Thank you for providing this. It looks like exactly what i have been looking for. Would it be possible to get the source code as well?

Also, is there a good resource that teaches how to build your own named expressions? I cant seem to find anything on the topic other than that you can do it and examples of how to use ones that are already existing.

No. I released this SymbolProvider several years ago as freeware, so right now it's closed solution. I thought already to put it as open source to e.g. GitHub, but because of total lack of time it will not happen soon. The development is based on playing with a code without detail documentation, so before such migration will happen, I want to be sure the code is correct ... and personally I have also to be clear I really want to open and share my not small invested effort and time ;-)

As far as I know there is no documentation and SymbolProvider API is not a part of standard MicroStation API, there are only functions to work with existing providers and expressions. I did my testing and research based on notes from BDN conference several years ago (I guess it was 2008), I don't know about any other. So if you are BDN member, you should have access to the materials.

I have no problem to add or modify the functionality if there will be valuable request and enough time to implement it, as I already did with some my other free tools in the past.

In addition to Jan's add-in please note you can find a sample included in the MicroStation V8i MDL SDK showing how to implement a SymbolProvider (similar to Jan’s example) located here: ..\dotnet\examples\NamedExprTest
