Uploaded image into thumbnail
-
hi to all, I am using asp.net 2.0, in that I designed a webpage for uploading an image. If the user uploads an image it should be automatically change in to thumbnail and it is displayed in that website. I searched in Google but I didn’t get the proper coding for that. So, please help.

I gave you the link to the documentation that shows you how to use the
Image.GetThumbnailImagemethod to create a thumbnail image. The other tasks - uploading an image, saving an image to the file system, displaying an image in a web page should be trivial. What is it that you don't understand? There will be plenty of examples on the web to implement these individual tasks if you search for them. You're not going to find a single article where you can cut-and-paste the code to immediately solve your problem. As a developer, you should be able to apply your problem-solving and research skills to find a solution. It's not going to be handed on a plate to you.Paul Marfleet

Hi, Jai, I have sending you the code from one of my application, please change it accordingly and let me know when done...... :) And it's only for jpg, and u cna do it for any one..... :) :) :) protected void Button2_Click(object sender, EventArgs e) { string sSavePath; string sThumbExtension; int intThumbWidth; int intThumbHeight; sSavePath = _Default.fullpath; sThumbExtension = "_thumb"; intThumbWidth = 160; intThumbHeight = 120; // If file field isn’t empty if (FileUpload1.PostedFile != null) { // Check file size (mustn’t be 0) HttpPostedFile myFile = FileUpload1.PostedFile; int nFileLen = myFile.ContentLength; if (nFileLen == 0) { lblOutput.Text = "No file was uploaded."; return; } // Check file extension (must be JPG) if (System.IO.Path.GetExtension(myFile.FileName).ToLower() != ".jpg") { lblOutput.Text = "The file must have an extension of JPG"; return; } // Read file into a data stream byte[] myData = new Byte[nFileLen]; myFile.InputStream.Read(myData, 0, nFileLen); // Make sure a duplicate file doesn’t exist. If it does, keep on appending an // incremental numeric until it is unique string sFilename = System.IO.Path.GetFileName(myFile.FileName); int file_append = 0; while (System.IO.File.Exists(( (sSavePath + sFilename)))) { file_append++; sFilename = System.IO.Path.GetFileNameWithoutExtension(myFile.FileName) + file_append.ToString() + ".jpg"; } // Save the stream to disk System.IO.FileStream newFile = new System.IO.FileStream((sSavePath + sFilename), System.IO.FileMode.Create); newFile.Write(myData, 0, myData.Length); newFile.Close(); // Check whether the file is really a JPEG by opening it System.Drawing.Image.GetThumbnailImageAbort myCallBack = new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback); Bitmap myBitmap; try { myBitmap = new Bitmap((sSavePath + sFilename)); // If jpg file is a jpeg, create a thumbnail filename that is unique. file_append = 0; string sThumbFile = System.IO.Path.GetFileNam
