Visual Studio crashing when mousing over BO in object tray

Govinda Berrio — Tue, 24 Jun 2008 14:10:35 GMT

I just tried this on a fresh VS 2008 project. I start a project using the Stataframe Windows Application (no security) template. Add a Strataframe Standard form. Add a Stataframe BO. I start the BO Mapper and point it at the database (SQL Server 2005 Express), just one table dbo.Lookups. Build the partial. Close BO Mapper. ReBuild the project, everything compiles fine. I can add the BO to the new form by dragging it from the toolbox. But... when I *mouse* over the the BO in the object tray I get a Visual Studio error without much information to glean anything from. (But I can send to Microsoft for their information.)

I've attached the table that I'm getting this with. Any help would be great.

If you place the column name in brackets it may have resolved your problem:

[codesnippet]Public Property [Locked] As String
...
End Property[/codesnippet]

This is an escape for reserved words (including intrinsic ones). You might try that to see if the problem goes away. Just an idea :)

OK! I figured something out. (Thanks to Trent ;))

I just started renaming columns one-by-one and found that VS just doesn't like it when you name a column "Locked". As far as I know it's not a keyword in SQL Server 2005, maybe it's stepping on a BO class member, since the column name becomes a property of the BO. But why did rebuilding the partial fix it on your machine, Trent? (rhetorical)

Anyway, I hope this thread helps someone else someday.

Govinda,

I am not sure that you had as I did not see any strong-typed properties in the sample that you sent me. I saw that you had everything structured, etc. But I just mapped to the Customers table in the StrataFrameSample database and all was well. One thing that I did not think if you did map, is what you mapped to. Does your structure use any reserved words, have spaces, or anything funny like that?

Hi Govinda,

Yes there is a new beta version released yesterday at http://forum.strataframe.net/FindPost17255.aspx

I've done that several time at this point and it hasn't fixed the problem here.

I'm running SF version 1.6.5.1. Is there another version I can try?

OK, I am not sure exactly why this was making VS die, but it failed on my side as well. However, to fix the problem, all I had to do was go into the BO Mapper, map the BO, build the partial class, and then rebuild the solution. Once I did this, all was well.

Thanks Trent,

here's the VS solution....

Also, this doesn't happen with any other BOs that I'm working with. And if I don't mouse over the BO everything else is working fine. So, lets say there is a problem with the Component or MarshalByRefComponent class, what's the fix for that? Try reinstalling VS?

Wow...that makes absolutely no sense whatsoever :crazy:

Mousing over a BO within a designer doesn't do anything, so this is really strange. In fact, since a BO isn't a UI component and inherits from a Component within the component model, there are no UI events! So even if we wanted to do something in the mouse over within the designer or run-time...we couldn't!

You are welcome to post the solution and I will see if the same results happen on this side...but I have a feeling that there is something going in within your VS environment in regards to any Component or MarshalByRefComponent class.
