how do I display an image I have downloaded via qr bar code scan

[mb1793]

Hello, I am currently working on an application that downloads an image from the web via qr bar-code scan of a download link. When I run the program no error is given , bu the imageview remains blank . I've tried the flicker example using httputils2 and nothing seems to work. what am I doing wrong? why is the downloaded image not displaying ? I appreciate any help in advance.

thanks,

You have only uploaded the main activity code. You should use File - Export as zip.

Not sure that I understand your code:

Sub myABBarcode_BarcodeFound (barCode As String, formatName As String)
   Activity.LoadLayout ("imagedisplay")
   Label1.Text = barCode ' establishes text on label#1 as a barcode reading
   'mResult = barCode ' establishes mresult as barcode reading
End Sub

This code will not start any activity. It will just load the layout file named imagedisplay.bal.

so would i use an activity initialize statement ? i apologize i am a fairly new to this .the closest example that ive been able to find in to my problem is the httputils 2 flickr example. and i am unable to infer upon a solution from that code.

do i need to create a seperate download activity?

If you want to start a new activity then you should call StartActivity(<TargetActivity>).

You can download an image to the current activity. If I remember correctly the example included with HttpUtils2 downloads an image and sets it as the activity background.

when I attempt to use the start activity command I receive an error message saying that I am missing a parameter. and when I attempt to set the image message as my background it appears under the previous activities.Is there a way to set the image as my background if my program creates multiple activities stacked 1 upon the other?

You will have to handle download result in new activity or you will have to call function in new activity after downloading the image.

Can you post your code?

Yes.
