here is a code snip i am using but when i save a jpg with this code it is 24 bit grayscale saveJpeg(file1,img,8); private void saveJpeg(string path, Bitmap img, long quality) { // Encoder parameter for image quality EncoderParameter qualityParam = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, quality); // Jpeg image codec ImageCodecInfo jpegCodec = this.getEncoderInfo("image/jpeg"); if (jpegCodec == null) return; EncoderParameters encoderParams = new EncoderParameters(1); encoderParams.Param[0] = qualityParam; img.Save(path, jpegCodec, encoderParams); } private ImageCodecInfo getEncoderInfo(string mimeType) { // Get image codecs for all image formats ImageCodecInfo[] codecs = ImageCodecInfo.GetImageEncoders(); // Find the correct image codec for (int i = 0; i < codecs.Length; i++) if (codecs[i].MimeType == mimeType) return codecs[i]; return null; }

the dll is a csharp dll i want to implment a menu that i can add calls to a dll at a later time for examlpl i would have a job that downloads files from a ftp site and uses the files to update a back end database and i could also have another job that downloads some zip file for a user to process at a latter time. and i was thinking it would be easier if i just had one menu that i could add ref. to different dll's to handel the custom job's i want to setup rather than recompiling the menu each time

Thanks, Chad Aiena

i have a program that i want to be able to dynamicaly add ref to dll that i build at a latter date. my plan is to store these ref. is an xml file and when i run my program read the xml file and add the ref to the dll's. but i am unsure how to add dll ref to a already compailed program
