PictureBox reverts to previously selected image

[Brandon Arnold]

I'm having an issue that I can't quite figure out. I have a
PictureBox that initially sets a picture from an embedded resource.
The user clicks a listview item and if an image url is available, it
sets the ImageLocation property to the url of the image and loads it.
Then if the user clicks a ListView item without an image url, the
default embedded image is displayed. This all works great, but if I
click an item with an image url, then one without, after a second the
previous image is displayed, replacing the default. I've run it
through a debugger and it doesn't catch where the change is happening,
I only set the image twice in my code from one method, once to set the
image from a URL, once to set it from the resources. Debugging
doesn't pick up where it gets reverted back and I don't know where to
look. There's no "ImageChang ed" type event so I can't watch for that.

Here's the code where it changes:

private void lstAds_Selected IndexChanged(ob ject sender, EventArgs e)
{
foreach (adComponents ad in clsock.adList.K eys)
{
if (lstAds.Focused Item.SubItems[1].Text ==
ad.description)
{
if (ad.hasPic)
pbxPreview.Imag eLocation = ad.picLink;
else
pbxPreview.Imag e =
Image.FromStrea m(
this.GetType(). Assembly.GetMan ifestResourceSt ream(
"creader.Resour ces.noimg.png") );
break;
}
}
}

I really don't know what to do now. If you need any other info, let
me know.

Thanks,
Brandon

Have you tried setting the ImageLocation property back to null when you
set an Image explicitly?

No, but that sounds like a good idea, i'll try that and get back.

Thanks,
