loaddwg drawdwg (help!)
loaddwg drawdwg (help!)
we recently joined the open design alliance as associate member for the purpose of being able to load and display (2d) dwg files in our "dredging support software". looking at the example program (odamfcapp) thus far this seems te be "somewhat" difficult to do. i need to be able to create a class (let's call it dwg), an instantiation of which can load a (dwg) file (dwg::loaddwg(lpctstr)) and then various threads can access the object and have it draw it's contents onto a memory dc (dwg:: draw(hdc hmemdc)) without erasing the background. i should be able to find out how to do this, but i am sure this will take quite some effort on my part while it seems probable that somebody has already done something similar and can show me how to do this. in the example mentioned above the dwg support is very much integrated into the application, view and document classes which for my purpose is not desirable, it needs to be a standalone class.
so if somebody can show me how to achieve the described objectives i would be most gratefull.
