Hello,
I have begun to work on a prototype of a plugin to ArcMap 10.1. It works on our computers and for some customers, but other customers get an exception.
Exception message:
IDataLayer2 dataLayer = ...
IDataset dataset = dataLayer as IDataset;
try
{
catch (Exception e)
{
...
}
So, it seems that the call to dataset.Workspace.Type throws an exception. What could cause that?
I noticed that there is a boolean method I could have called,
if (dataset.Workspace.Exists())
but if I get an exception just by getting the Workspace, I assume that I would never reach the Exists() method.
And I don't see what non-existence means. Is it the same as "file not found"?
I would be grateful for any help.
