    Hi there
    I am trying to download an image from a remote server and load it with an imageviewer.
    It downloades the image but i can't see anything.

    Here some portions of the code:

    The downloader code is
    down.Download("" & Username.text & ".jpg")
    After download is finished:
    If Job.JobName="downloaded" Then
    Msgbox("Photo downloaded" & Job.GetBitmap, "OK")
    End If
    Nothing happens on errors, no images, nothing.
    The MsgBox says: "Photo downloaded(Bitmap): 250x400"
    Anyone can help me?

    The URI is a little strange, but if you don't get some error, maybe it is ok.

    Are you sure the ImageView1 is visible? Is it on foreground (BringToFront)?

    I found the problem.
    I created the ImageView1 element with the designer and then i initialized it in the Sub Activity_Create with
    The B4A editor sometimes warns me saying that i shouldn't initialize the object because it is already initialized(?) by the designer. In any case the program runs correctly with no errors.
    If i comment out the initialization command of ImageView1 everything works fine and the image is correctly loaded into ImageView.

    That sounds strange for me.

    Why you initialize it when you have loaded it with the designer. Designerviews dont need to initialized
