VC# .NET 2.0
Mappoint 2006

Hello guys,

My client uses my map application quite a while, but he contacted me for an error with the message: "Import failed"

I analized my source and found out that the message is from an exception, where I haven't done any processing with it, except just showing the error message.

In the try block I create a pushpin, location and a symbol. But I don't know which one failed. Does anyone know what can cause the exception "Import failed"?

Thank you very much for your help.

Is there really no one who can explain this exception??

Hello friends,

I found the cause of the "Import failed" exception! It is caused when calling objSymbol = Map.Symbols.Add(GetFileName);
This was doing well all the time, untill I loaded 997th symbol image. It's like there is a limit of loading symbols, but is there really a limit on loading symbols?

It's so frustrating, isn't there a real solution for that?
Please, help me out guys!

Extra info:
I use the same filename but that shouldn't be the problem right?
Everytime I get a position, I draw a new bmp file with the same name and that bmp file is than loaded again when adding a symbol. And that should be more than thousand...but why did it throw an exception? I checked the filename, the bitmap everything seems to be ok, but according to debugging info it fails to load more symbols.

There is a limit, but I thought the total was more like 65536 - including those pre-loaded.

Hi Winwaed,

Thanks for your post, well there is really a limit on loading symbols. The thing is, it's like loading a library of icons and using thousands of icons seems not to be practical from the Mappoint developers's view. Maybe the main usage of Mappoint is to use it as a Mappoint application itself not as a COM object.

So I guess when they were developing Mappoint, they thought it's a bit silly to make it possible to use more than thousand icons for the pushpins. I can agree with them from that point of view (POV). So I have to modify my source to work around.

Thank you.
