Type a page name and press Enter. You'll jump to the page if it exists, or you can create it if it doesn't.
To create a page in a module other than shell32, prefix the name with the module name and a period.
Consider a Winform application with a OpenFileDialog that helps pick some file. This is then passed to the ExtractAssociatedIcon method to get the icon and display in a picture box.
public partial class IconTest : Form
{
[DllImport("shell32.dll")]
static extern IntPtr ExtractAssociatedIcon(IntPtr hInst, StringBuilder lpIconPath,
out ushort lpiIcon);
[DllImport("shell32.dll")]
static extern IntPtr ExtractIcon(IntPtr hInst, string lpszExeFileName, int nIconIndex);
ushort uicon;
StringBuilder strB = new StringBuilder(openFileDialog1.FileName);
IntPtr handle = ExtractAssociatedIcon(this.Handle, strB, out uicon);
Icon ico = Icon.FromHandle(handle);
pictureBox1.Image = ico.ToBitmap();
}
}
}
Alternative Managed API:
Use static method 'System.Drawing.Icon.ExtractAssociatedIcon(string filePath)' in assembly 'System.Drawing.dll' (.net 2)
