|
Hi,
I'm trying to load a picture from the internet to a picture box, but I get "URI Formats are not supported" exception.
I tried using System.Net to see if I can download the picture or something, but I really don't know how to do it...
I did:
| Code: | | this.BackgroundImage = Image.FromFile("http://....com/....png"); |
|

You can't pass a URL and expect it to download
you HAVE to call the downloading function and passing that to it.

As in getting a parameter using another function.

I think it's just a simple DownloadFile call o.o
URLDownloadToFile
This will download the file to a file on the harddrive then you can call that file.
C Example
| Code: | #include <urlmon.h>
#include <stdio.h>
IBindStatusCallback *stat;
char* file = "http://img174.imageshack.us/img174/9614/lawlep9.jpg";
int main(){
if(URLDownloadToFile(0,file,"pic.jpg",0,stat))
{
MessageBox(0,"Error:\nFile Not Found or you are offline","Error",MB_OK | MB_ICONERROR);
return 1;
}
return 0;
} |
Then of course you could always delete the image RIGHT after you use it and the user wouldn't know

Here's some C# that might help you:
| Code: |
//using System.Net;
WebClient Client = new WebClient ();
Client.DownloadFile("website", "path");
picMyPicture.Picture = "path"; //I have no idea how to work with these, so you're on your own here; just sorta threw you a bone. =P

Thanks you two. 
Edit: not sure how to convert URLDownloadToFile to C# and where does WebClient download the files to? O_O
