I first would like to warn you that I'm a newbie programmer. So if I have left out important code for you guys to determine what I'm doing wrong, let me know.
I am making a PocketPC application using C# and an XML file as a database. I would like to display the corresponding JPG image in a PictureBox, or somewhere on the main page.
A sample of my xml file. The bolded line is the picture reference.
<
fragenkatalog>
<
ca_id >4</ ca_id>
<
ca_titel>head ap</ca_titel>
<
ca_bildurl1>kopf_ap.jpg</ca_bildurl1>
<
ca_disabled>0</ca_disabled>
<
ca_alter>999</ca_alter>
<
ca_sex>n</ca_sex>
</
fragenkatalog>
This is what I have, which doesn't work.
//Bind image to picturebox
ca_bildurl.DataBindings.Add("Image",dt,"ca_bildurl1");The ID is chosen from a ListBox, and the corresponding data is displayed on the screen.
Any help would be appreciated! Thanks!

This may be an error on your part via typing but I noticed the following:
<ca_id >4</ ca_id>
There's a space between "</" and "ca_id>".

//this
.ca_bildurl.Image = ((System.Drawing.Image)(resources.GetObject("ca_bildurl1.Image")));Update. Worked on the file a little over the holidays. I think I'm closer, but not sure. :S
The bolded parts are the references to the picturebox. I get only one error message, and that's the Cannot implicitly convert type 'string' to 'System.Drawing.Image'.
Basically what I'm thinking is that I want to say, "For this picturebox 'jpg' image path, use the text found in 'ca_bildurl1' in the xml file for this particular id. It worked so far for the text/labels. The images are located in the same directory as the other files.
Any ideas Thanks again!

Can you paste the error message please
Also, what is ca_id
dev15`4534345677
Certainly does. And thanks everyone for helping newbies like me!

Thanks for that info, it was an error of my typing. The code itself doesn't have that.
I really don't have an error message, it's just I don't know how to get the picture to show up in the picturebox.
ca_id is the ID #.
