causing exception while saving hatch!
causing exception while saving hatch!
i found that it causing exception while saving hatch. but it do not cause exception when i install autocad 2000 on my compter.
maybe it can find the "*.pat" file about the hatch when i installed autocad 2000.
the problem is that what should i do to make i can to save hatch when i do not install autocad 2000 on my computer. how can i to set the path of "*.pat",so it can find the "*.pat" files and it can initialize pattern manager.
thanks a lot.

it seems that you use code form odamfcapp which searches the registry for installed autocad and uses it's files. as a result your program will work only if autocad is installed. more safe way is to provide *.pat file with your application and be sure that your override of oddbhostservices::findfile() is able to locate it.
but note that original autocad's .pat file is copyrighted and you may have legal problems redistributing it.
also where is a way to not use *.pat files at all. patterns can be created programmatically using hatchpatternmanager methods.
see odwriteex sample - creating my_stars pattern.
