The resource file or better the icon has got a 48 x 48 icon with a color depth of 256 colors. The paint box is of 48 x 48 - exactly like the icon I want to paint. However the drawn icon seems to be smaller and looks like DrawIcon() had resized it. Is DrawIcon capable of doing this? If so how do I prevent this function to not behave like this? Thx, -- cu, Michael Back to top Peter Below (TeamB) Guest Posted: Mon Nov 22, 2004 7:13 pm    Post subject: Re: DrawIcon into TPaintBox draws ugly In article <s8gfz8uel1zh.dlg (AT) die-fritzens (DOT) de>, Michael Fritz wrote: Quote: I'm using DrawIcon to draw an icon from a resource file onto a TPaintBox.

Use DrawImage or DrawIconEx instead, it allows you to specify the size you want. DrawIcon always draws a 32*32 icon. -- Peter Below (TeamB) Use the newsgroup archives : http://www.mers.com/searchsite.html http://www.tamaracka.com/search.htm http://groups.google.com http://www.prolix.be Back to top Michael Fritz Guest Posted: Mon Nov 22, 2004 7:40 pm    Post subject: Re: DrawIcon into TPaintBox draws ugly Am Mon, 22 Nov 2004 20:13:27 +0100 schrieb Peter Below (TeamB): Quote: Use DrawImage or DrawIconEx instead, it allows you to specify the size you want.

No. I'll try to remember to do that tomorrow. I don't have a permanent online connection, so it's a bit awkward for me to get things out of b.p.attachments on short notice. -- Peter Below (TeamB) Use the newsgroup archives : http://www.mers.com/searchsite.html http://www.tamaracka.com/search.htm http://groups.google.com http://www.prolix.be Back to top Michael Fritz Guest Posted: Thu Nov 25, 2004 10:32 am    Post subject: Re: DrawIcon into TPaintBox draws ugly "Peter Below (TeamB)" wrote in message <news:VA.0000b549.004fa868 (AT) nomail (DOT) please>: Quote: No. I'll try to remember to do that tomorrow.

You are using LoadIcon to get the icon from resource. And the SDK docs for this function have this remark: "LoadIcon can only load an icon whose size conforms to the SM_CXICON and SM_CYICON system metric values. Use the LoadImage function to load icons of other sizes." This limitation of LoadIcon is the source of your trouble. So do as MS suggests and use LoadImage instead.
