how to extract a specific icon from an .ico file?

[Mehdi Mousavi]

Hi,
I need to know how to extract a specific icon (32x32 for instance) from an
icon file that contains more than one icon size?

Any help would be highly appreciated,

Cheers.
Mehdi

Well, thanks. Would you please tell me how to do the same thing using the
resource files? I mean what if I store my icon in the resource file?

Thank you for your time,
Mehdi

Try this ;-)

Icon icon1 = IconFactory (@"C:\hoge.ico", 32, 32);

Hi,

Well, thanks. Would you please tell me how to do the same thing using the
resource files? I mean what if I store my icon in the resource file?
Does resource files means manifest resource?
Hum.. can Compact Framwork project can includes manifest resource?

What's the manifest resource? I meant the ".resx" files. Sorry for being
this dumb, but I'm not a C# (nor a .NET) programmer.

Hi,

What's the manifest resource?
Sorry, I used "manifest resource" to mean the .NET resource in main seemlby.
I meant the ".resx" files. Sorry for being
".resx" can contains only string data. and ".resx" is .NET resource, is not
legacy Win32 resource.

In Compact Framework project, I guess (sorry, I had never check it up) that
the legacy Win32 resources (.ico , .bmp, and so on) are put on there
(=application folder) *as is*.
