Hi All,
I have a problem with this piece of code:
string fileName = Label1.Text.Replace(" ","_") + ".jpg";
string localImageUrl = Server.MapPath(@"Images\" + fileName);The image does not show. When I ommit @Images\ abn move the images to the root of the project the image does show.
any ideas?
Regards,
Frank
Take a look in the debugger at the full path:
string localImageUrl1 = Server.MapPath(@"Images\" + fileName);
string localImageUrl2 = Server.MapPath(fileName);
System.Diagnostics.Debugger.Break();Compare the two strings and see what the difference is. Also -- What does your directory structure look like where the image is housed?
there is no difference in the strings other than "Images" :
"C:\Users\frank\Documents\Visual Studio 2005\Projects\WebApplication3\WebApplication3\Images\Meetstation_Berkhout.jpg"
"C:\Users\frank\Documents\Visual Studio 2005\Projects\WebApplication3\WebApplication3\Meetstation_Berkhout.jpg"
I attached the structure of my project.
Thanks
Frank
Server.MapPath() gives you the local image path but you need to reference the virtual path in your web project. Can you post code for the entire page?
Here is the code enjoy:)

}According to your code:
string Imageloc = list1[ListBox1.SelectedIndex].ChildNodes[15].InnerText;
string localImageUrl1 = Server.MapPath(@"Images\" + fileName);
string localImageUrl2 = Server.MapPath(fileName);
Image1.ImageUrl = Imageloc;
Image2.ImageUrl = localImageUrl1;You're comparing the working image to the listBox selected item and localImageUrl2. You described comparing localImageUrl1/localImageUrl2. What does "Imageloc" evaluate to in the designer?
It looks like you may have your wires crossed here.

unless those are intended to be two separate images?
Yes, these are two seperate images.
