My manager is currently sailing back from Honolulu to San Francisco, after his boat came 2nd in its division in the 2008 Pacific Cup (congratulations, Jim! :-), so I'm spending more time on management-related activities than I would normally. Which means I'm getting less time to spend on the fun stuff, such as researching blog posts: I'm plundering what I can from my email archives, but my output may feel a little thin over the next week or two.
Here's some information from an internal discussion that I thought might be of general interest.
Why is it important to use Application.ShowModalDialog() or Application.ShowModelessDialog()? The documentation for both these commands says "You must use this method instead of Form.Show[Dialog], which may lead to unexpected behavior." Any pointers as to what the "unexpected behavior" might be?
Here's the answer, provided by a member of the AutoCAD Engineering team:
There are a number of reasons to use Application.Show[Modal/Modeless]Dialog() rather than Form.Show[Dialog]:
- Dialogs will automatically pick up the icon of the host product
- Dialog size and position will be persisted automatically
- Other floating AutoCAD windows (e.g. the Properties palette) will be disabled, as needed
- The DIASTAT system variable will be set properly with the exit status of the dialog
