I'm not exactly sure what your asking for. Are you asking how to extract an icon from an exe file? Or are you asking for extracting an image from a URL?

I'm confused can you please be more specific and add more info so we can help you?

this is my code so far

try
{
//Gets the icon associated with the currently executing assembly
//(or pass a different file path and name for a different executable)
Icon appIcon = Icon.ExtractAssociatedIcon(textbox1.Text);
pictureBox1.Image = appIcon.ToBitmap();
}
catch (ArgumentException ae)
{
//handle
}

the textbox holds the file location, good news! a picure comes up, but the bad news is that i get a defult icon, looks blank and dose it for all locations

I tested this and got a nice icon from the executable (prg.exe -> icon.ico)
Try to save the bitmap (as I show in my updated answer) to see if the icon is correct.

What do you mean?

I get the URL C:\Users\pc\AppData\Roaming\Dropbox\bin\Dropbox.exe

And as all programs, they have an icon with it (ico), I want to get that ico/icon from that file location and put it in a picutebox

C#

appIcon.ToBitmap().Save("D:\\icon.ico");

will save a bitmap file renamed to ico, not a valid icon file.

To save it as a valid icon file you will have to use filestream:

C#

// Create a stream
FileStream fs = new FileStream("D:\\icon.ico",
            FileMode.OpenOrCreate);
// Save the icon
appIcon.Save(fs);
// Close the filestream
fs.Close();
