    How do i prevent the file from being saved to the tempdirectory when i am OpenStream to save the image myself ...

    Reply Quote
    I am trying to develop a page that will upload image.  Once the _UploadCompleted event is trigger I uses args.OpenStream to create a new drawing image that i use to shrink and convert the image into png with rounded corners.  I than save the file into a specific folder on my server.  My Problem is the control is still coping a version of the file to the TempDirectory Folder.
     
    Is there a way to stop this? or do i just have to delete the file later?
     
    Also, which event should i place my code in?
    protected void PersistedFile1_FileUploaded(object sender, UploaderEventArgs args)
    protected void PersistedFile1_FileValidating(object sender, UploaderEventArgs args)
    protected void PersistedFile1_UploadCompleted(object sender, UploaderEventArgs[] args)
    protected void PersistedFile1_Init(object sender, EventArgs e);


    The Code i use to copy the upload file..
    int     roundedDia = 25;
    System.Drawing.Image myImage = System.Drawing.Image.FromStream( args.OpenStream() );
    Bitmap bitmap = new Bitmap(imgin.Width, imgin.Height);
    Graphics g = Graphics.FromImage(bitmap);
    g.Clear(    Color.Transparent);
    g.SmoothingMode = (System.Drawing.Drawing2D.    SmoothingMode.AntiAlias);
    Brush brush = new System.Drawing.TextureBrush(imgin);
    FillRoundedRectangle(g,     new Rectangle(0, 0, imgin.Width, imgin.Height), roundedDia, brush);
    bitmap.Save(@mPath + "Completed" + ".png", System.Drawing.Imaging.ImageFormat.Png);

    ScottDolan,
     
    All temp files will be deleted automatically by ajax uploader. You don't need to maintain this TempDirectory Folder.

    Also, all the files uploaded to the tempDirectory are renamed to something similar to this
     
    "persisted.aa5b8ba2-4d86-4681-92a2-bff277698419.new.png.resx"   However, I would like to make use of this temporary image I just uploaded for a little bit while I am cropping the image.   Is there a way to control how the file is named in the temp directory..  Basically, i just need to remove the .resx from the file name but, i still want ajaxuploader to  delete after 5hrs goes by.

    Hi ScottDolan,
     
    Please use method "CopyTo" to save the upload file.
