So the parameter parentHWnd appears in a number of ArcObjects methods, such as IExportOperation.ExportFeatureClass.
Does anyone know what the parameter is?
I can't seem to find any explanation. The only value I've ever passed to it is 0. Passing 1 threw an exception that I didn't recognise.
The reason I ask is because I'm trying to figure out if it's possible to hide the "exporting features" progress dialogue that pops up when you call this method, and I'm wondering if this has something to do with it.
