Re: Collection Serialization Error: unable to convert to InstanceDescriptor

I have experienced that. Are you trying to call a specific constructor?

I found some noise that referenced a problem with the version resource using the '*' character. I removed that and it helped but only by making the problem inconsistent. I finally got tired of losing my collection and removed the use of the specific constructor.

Hmm this is odd... i'm not getting the bug anymore and i didn't do anything except close vs and open it again... zzz owell guess its just one of those things that never makes sense.

Or because your collection is now empty?

Looked at your TypeConverter. That is the same thing I had only I was getting a constructor with parameters. I would go along fine for days and then start producing that error. I finally got fed up with it and stopped using it. I hope you don't run into the same problem.

Wow bug is occuring again :P

I think it might be because their are files dependant on classes in other assemblies... or just a weird vs bug...rebuild and reloading vs.net isn't getting rid of error message.

Hmm did some googling and found lots of forums with people that had this problem. This one had some interesting info: http://www.dotnet247.com/247reference/msgs/53/267795.aspx

I seem to remember having a problem similar to this a while back and it was<br />
to do with the control version and the resources being out of whack.<br />
<br />
Edit your control's AssemblyInfo so that you have an explicit version<br />
number, not one with an asterisk in it. Ensure that you do a full rebuild<br />
and maybe even remove the control from the form it's on, the toolbox and<br />
anywhere else you might have it and then add it again using the new version.<br />
<br />
If this doesn't work then I'm sorry for the wild goose chase. It's all I can<br />
think of for now...<br />
<br />

Well i checked all the AssemblyInfo.cs files but i didnt see any "*" in the version number...all were by default 1.0.0.0 or something like that.

Tried removing control from form, but that didnt work. Couldnt figure how to remove items from toolbox other then resetting toolbox...zzz

Wow i got rid of bug...all i had to do was delete every bin and obj folder in the solution.

Wow i got bug back again... i think the cause is code being seperated in differant assembly projects

Ok all code that this control depends on is in a single assembly being referenced by a windows application project and so far no bug Big Grin | :-D

I blame vs 2005 entirely! or maybe theirs something i'm doing or not doing... hmm maybe i can find a book on this stuff for 05

Yeah, I think that is the same one I mentioned earlier. I did have the '*' in one of my version resources and when I changed it the problem went from "broken" to "intermitent".

I can't quite picture that from your statement could you clarify please? I will try to duplicate your solution in my project and see if it works for me. Smile | :)

No, it is definitely a bug. Cry | :((

Err the bug is back.

to re-explain my setup, my solution has a class library project with the control and its items and type converters and that generic event collection thing i made. In same solution, but in a windowsApplication project i reference the control library and drag it from the toolbox to a form.

So i think the bug here is that vs does something when presented with a control... like it "gets used to it" in some way...like when it generates the resx files or something like that. Then even if it seems to work,...you tinker with a property or part of this control and vs tries to re-"get used to it" and makes mistakes cause theirs items serialized in designer class or something...and then the error message... this is so lame lol

Thanks Smile | :)

Why does everyone expect others to write the code for them?

XmlElement is derived from XmlNode. To append a child node to a give node you would use the aptly named AppendChild method. To save the XmlDocument you would use the cleverly named Save method.

What might be the name of the method which one would use to load data into an XmlDocument? Laugh | :laugh:

I'm still relatively new to SQL and I was wondering whether there was an easier way to do things.
I need to limit a query based on if a field is like one of three values. I can use "WHERE field in ('list one', 'list two', 'list three')", and I can to "WHERE field like 'list one' or field like 'list two' or field like 'list three'". Is there a way, however, to combine 'in' and 'like' to do something like "WHERE field in like ('list one', 'list two', 'list three') ?

That sounds like Valley Girl SQL. Big Grin | :-D

You should post this to the SQL forum, you'll probably get more and faster responses than in the C# forum.
