If you are just interested in displaying dicom images, you can export or extract the image inside the dicom file, in .BMP, .JPG or whatever format you want, and use any regular image viewer. I´ve done some tests using this approach and binding images to asp:image and ImageButton succesfuly. If you tell me how are you dealing with dicom files (if you are using some library or stuff like that), i might help you with this topic. Regards, Pablo.-

Dirso, i was right, but incomplete... After doing some research i´ve found: .- How to define/use preprocessor directives http://www.c-sharpcorner.com/UploadFile/vgupta/PreprocessorDirectivesCS11162005235503PM/PreprocessorDirectivesCS.aspx[^] .- How to detect if you are running in MONO http://www.mono-project.com/FAQ:_Technical#How_can_I_detect_if_am_running_in_Mono.3F[^] .- Conditional Compilation http://bytes.com/forum/thread214072.html[^] HTH, Pablo.-

Hi Dirso, I'm not an expert in preprocessor directives (so, this post could be useless), but, thinking that .Net was made only for Windows (MONO was developed after) i've seen one that might help you: #if !MONO #endif I think that this was made on purpose... If you want yo know if you are in MONO, ask for it... Windows is assume. HTH Dirso, Pablo.-
