This is useful if you want to //compare the clipboard formats used by two different applications. using System; using System.Text; using System.Windows.Forms; using System.Runtime.InteropServices; namespace ClipBoardTest { public partial class Form1 : Form { [DllImport("user32.dll")] static extern uint EnumClipboardFormats(uint format); [DllImport("user32.dll")] static extern bool OpenClipboard(IntPtr hWndNewOwner); [DllImport("user32.dll")] static extern bool CloseClipboard(); [DllImport("user32.dll")] static extern int GetClipboardFormatName(uint format, [Out] StringBuilder lpszFormatName, int cchMaxCount); public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { OpenClipboard(Handle); listBox1.Items.Clear(); uint LastRetrievedFormat = 0; while (0 != (LastRetrievedFormat = EnumClipboardFormats(LastRetrievedFormat))) { String Description = "[" + LastRetrievedFormat.ToString() + "] \t" + GetClipboardFormatName(LastRetrievedFormat); listBox1.Items.Add(Description); } CloseClipboard(); } private String GetClipboardFormatName(uint ClipboardFormat) { StringBuilder sb = new StringBuilder(1000); GetClipboardFormatName(ClipboardFormat, sb, sb.Capacity); return sb.ToString(); } private void button2_Click(object sender, EventArgs e) { listBox2.Items.Clear(); foreach (var Item in listBox1.Items) { listBox2.Items.Add(Item); } } } } !!!!Alternative Managed API: Do you know one?
