1.1 equivalent for Drawing.Icon.ExtractAssociatedIcon?Hi,
I need to have the icon of the assembly that is calling my Control.Library. Using 2.0 Framework the "Drawing.Icon.ExtractAssociatedIcon" does the trick. But this fucntion doesn't exist in the .NET 1.1 Framework, and my control Library must be able to be compiled in 1.1 too. Does anybody knows the solution? thanks a lot in advance, Pieter Hi,
Create a P/Invoke declaration for the ExtractIcon API function, then use Icon.FromHandle and pass the handle ExtractIcon returned as the parameter. Ready-made P/Invoke declaration can be found here: http://www.pinvoke.net/default.aspx/shell32/ExtractIcon.html Show quote "Pieter" <pieterNOSPAMcoucke@hotmail.com> wrote in message news:%231kz0Xi5GHA.2536@TK2MSFTNGP06.phx.gbl... > Hi, > > I need to have the icon of the assembly that is calling my > Control.Library.

This worked for me: Declare Function ExtractIcon Lib "shell32.dll" Alias "ExtractIconA" (ByVal hInst As Integer, ByVal lpszExeFileName As String, ByVal nIconIndex As Integer) As IntPtr Dim ico As Icon Dim hIcon As IntPtr ' handle to the icon once it is extracted hIcon = ExtractIcon(Microsoft.VisualBasic.Compatibility.VB6.GetHInstance.ToInt32, ConfigParentAssembly.Location, 0) ico = Icon.FromHandle(hIcon) m_ConfigIcon = New Icon(ico, New Size(16, 16)) (ConfigParentAssembly is the System.Reflection.assembly which is calling the dll, and m_ConfigIcon an Icon-variable.) Hi,
One thing to note. When you use FromHandle, the new Icon instance does not take ownership of the handle. This means that when the Icon instance is disposed the handle is not released, resulting in a resource leak. You need to call DestroyIcon on the original handle, this will of course invalidate the icon handle referenced by the Icon instance, so what you need to do is first clone the icon which will create a new Icon instance which owns the new Icon handle, allowing you to free the original handle. ico = Icon.FromHandle(hIcon).Clone(); DestroyIcon(hIcon); // You need to pinvoke DestroyIcon.

I did a quick google search and came up with this. http://www.codeproject.com/system/winlogon_notification_package.asp Hope this helps Show quote "Pieter" <pieterNOSPAMcoucke@hotmail.com> wrote in message news:%23K8Ow5r5GHA.1244@TK2MSFTNGP03.phx.gbl... > ok thanks for the hint! > Oops sorry, wrong thread
