Hi,

 

I can get the thumbnail view of the active document from below code

 

Document doc = Application.DocumentManager.MdiActiveDocument;
System.Drawing.Bitmap bit = doc.Database.ThumbnailBitmap;

 

 

How can i get the thumbnail view of the dwg file by passing filename means like below.

 

Document doc = .....(fileName)  :  here fileName is dwg file.

 

Please advise on this issue.

 

Regards,

Raman

 

 

 

 

Hi,

 

Why do you have to use the AutoCAD API if you can get the same result without it?

if you want to calculate sin(alpha) ... what could be the reason for doing that with a specific API from AutoCAD instead of the global Math-namespace?

 

Sorry if I bother you, I'd like to understand why doing something more complex that can be achieved in an easy way (ready to use and independet from any AutoCAD release).

Hi,

 

it's just copy&paste, compile and test .... so why not trying it?

 

And if you look to the code you'll see it does not use any AutoCAD-lib-functions. so it's independent from any AutoCAD-version (it just reads the icon-part of the image header)
