Error Reporting

[Nem]

I'm almost done a plug-in based off the DDS plug-in, and I have a few questions before I complete it.

1) There are a few restrictions on the file format that I'm writing a plug-in for (e.g. the width and height of the image must be a power of two). How should I report these errors to the user? Is there a specific exception I must throw? Should I throw nothing and just show a message box (and not write to the stream)?

If I throw an exception all the user sees is: "There was an unspecified error while saving the file."

2) I'm not exactly a C# expert. Does the Guid need to be a unique random number? Is it supposed to be 8a543b8c-769f-44a2-a59a-fdfe6e6a1f20?

3) Is there any way I can better control the size of the SaveConfigWidget? The format I'm writing has a lot of options and it's really hard to squish them all into a small area without scrolling.

Thanks,

Nem

Summary: This is not really important, just remove this line.

1) Just throw a FormatException. THere is no way for a codec to provide a customized error message.

2) You don't need a Guid anymore, we were planning on using them but I don't think we will be anymore.

3) No, you will just have to scroll.

Thanks for the quick response.

It would be nice if there was a way to provide error messages. As a work around, I just resized non power of two images to the nearest power of two. (Not ideal as users may wonder why the image is skewed, but more ideal than them just seeing "Error").
