.
Summary
Shows the common Pick-Icon-Dialog

C# Signature:

[DllImport("shell32.dll", CharSet=CharSet.Unicode)]
private static extern int PickIconDlg(IntPtr hwndOwner, System.Text.StringBuilder lpstrFile, int nMaxFile, ref int lpdwIconIndex);

VB Signature:

Declare Unicode Function PickIconDlg Lib "Shell32" Alias "PickIconDlg" (ByVal hwndOwner As IntPtr, ByVal lpstrFile As String, ByVal nMaxFile As Integer, ByRef lpdwIconIndex As Integer) As Integer

Notes:

This function behaves differently on 9x/ME than on Windows NT->XP

Tips & Tricks:

Please add some!

Sample Code:

C# Version:

string iconfile;
int iconindex = 0;
int retval;
System.Text.StringBuilder sb;

iconfile = Environment.GetFolderPath(Environment.SpecialFolder.System);
iconfile = iconfile + @"\shell32.dll";
sb = new System.Text.StringBuilder(iconfile, 500);
retval = PickIconDlg(this.Handle, sb, sb.Length + 1, ref iconindex);
iconfile = sb.ToString();

Shouldn't it look like this:

retval = PickIconDlg(this.Handle, sb, sb.Capacity, ref iconindex);

VB.NET Version:

Dim iconfile As String = Environment.GetFolderPath(Environment.SpecialFolder.System) + "\shell32.dll"

Dim iconindex As Integer ' Will store the index of the selected icon

Dim retval As Integer ' Will contain the result of the PickIconDlg. 1 = OK, 0 = Canceled

retval = PickIconDlg(Me.Handle, iconfile, iconfile.Length, iconindex)

MessageBox.Show("Result: " + retval.ToString() + vbCrLf + "Selected Icon Index: " + iconindex.ToString())
