.NET Forum / Languages / C# / March 2008ExtractAssociatedIcon Only 32*32?
Icon.ExtractAssociatedIcon() has no parameters. Surely we need all the sizes of icons when we actually writing applications, but it seems that ExtractAssociatedIcon returnes only one size, 32*32. How can I get other sizes like 16*16, 48*48? Is it impossible without P/Invoke? If there is a pure .NET way to do this please give me a tip. (If there isn't, what the heck is the rationale for providing only 32*32?) Thank you. > Icon.ExtractAssociatedIcon() has no parameters.

Thank > you. Icon.ExtractAssociatedIcon wraps the shell32 ExtractAssociatedIcon API which knows only the 32X32 format. Your only option is to PInvoke shel32's SHGetFileInfo, you might get more info from MSDN and http://pinvoke.net for a method declaration. Willy.

I hope Microsoft would provide more options for ExtractAssicicatedIcon, when they make the next version of the .NET Framework. Thank you, Willy.

I hope Microsoft would provide more options for ExtractAssicicatedIcon, when they make the next version of the .NET Framework. Thank you, Willy. This has nothing to do with the framework, it's the underlying API (shell32.dll) which only supports 32X32 bit ICON's. All they could do is wrap the SHGetFileInfo, but this ain't gonna happen because Windows.Forms will not get enhanced. Willy. Free MagazinesGet these publications absolutely FREE for up to 12 months.
