 Posted: Fri Feb 11, 2005 1:37 pm Post subject: Windows Icon capture? Possible? |
 |
|
Hi,
Wondering if anyone knows how to capture the window icon of any opened window?
For example if I wanted to capture the icon of an opened notepad, internet explorer, ect...
I search the forum, did not find anything about that (Unless I missed it)
Thank you, |

use the WM_GETICON API message with @sendmsg().
| Code: |
%%icon = @sendmsg(@winexists(someWindow), WM_GETICON, 0, 0)
|
I'mm not sure what the WM_GETICON message number is.
Set the 'wParam' member to zero'0' to get the big icon and one '1' for the
windows small icon.

As noted WM_GETICON is the way to get the icon.
Check the api handbook (www.vdsworld.com > search) as it has the exact numbers and explantion to use for WM_GETICON |

Hi Guys,
After determining the handle, how does one actually "capture" the icon?
Thanks,
- Boo |

You can't really capture the icon.
But with this icon handle you can use some of the other APIs like
DrawIcon() and any of the @sendmsg() codes that use an icon handle as
well.
