Hi,
I'm nearing the completion of my first WinForms app and have an issue that has stopped me in my tracks.
Basically, dropping a DataSet onto a form in the IDE generates an error dialog that says "Unspecified Error". And when i open a form that has datasets on it the same error occurs, except in the 'Output' window - and all the datasets are not shown on the form.
If I create a new WinForms project the problem does not occur - datasets can be added.
I've tried a few things to fix this. Most of these come from various postings around the place.
1. Delete all resx files in the project. This did resolve the problem but at too high a price as all the resource data throughout my many forms was lost.
2. Unbind the solution from SourceSafe. Made no difference.
3. Start a new solution and import all the forms/classes/etc into it. Did not help.
It's interesting to note that the project compiles and runs perfectly. I just cannot do anything with any datasets. As it's a database app, that means I cannot do anything.
Any advice would be nice. I'd love to understand how to debug the events surrounding dropping components onto forms, or how the designer progresses through a form's class and builds what you see in the IDE.
Thanks,
Lenny
