CreateIconIndirect()

5 posts in this topic

I can not get a combination of icons. CreateIconIndirect() function does not take the icon mask, or that I am doing something wrong? Please run my example and by all see.

Thanks.

I prepared a more simple example. Look in the comments.

#Include <WinAPI.au3>

local $Form, $sBackInfo, $sFrontInfo, $hBackIcon, $hFrontIcon, $hResultIcon

$Form = GUICreate('', 100, 100)
GUISetState()

; Get icons
$hBackIcon = _WinAPI_PrivateExtractIcon('shell32.dll', 0, 32, 32)
$hFrontIcon = _WinAPI_PrivateExtractIcon('shell32.dll', 28, 32, 32)

; Get information about icons
$sBackInfo = DllStructCreate('byte fIcon;dword xHotspot;dword yHotspot;ptr hbmMask;ptr hbmColor')
DllCall('user32.dll', 'int', 'GetIconInfo', 'hwnd', $hBackIcon, 'ptr', DllStructGetPtr($sBackInfo))
$sFrontInfo = DllStructCreate('byte fIcon;dword xHotspot;dword yHotspot;ptr hbmMask;ptr hbmColor')
DllCall('user32.dll', 'int', 'GetIconInfo', 'hwnd', $hFrontIcon, 'ptr', DllStructGetPtr($sFrontInfo))

; Specifying the bottom icon mask from the top icon
DllStructSetData($sBackInfo, 'hbmMask', DllStructGetData($sFrontInfo, 'hbmMask'))
;DllStructSetData($sBackInfo, 'hbmColor', DllStructGetData($sFrontInfo, 'hbmColor'))

; Create a new icon
$hResultIcon = _WinAPI_CreateIconIndirect($sBackInfo)

; Results obtained in the bottom icon in the original form
; Why?
_WinAPI_DrawIcon(_WinAPI_GetDC($Form), 34, 34, $hResultIcon)

I'm not sure what you're trying to achieve here; are you trying to superimpose one icon on to another? If so, I don't think you're quite on the right lines here as you're replacing the bitmap mask from one with a mask from another one. In addition, a BOOL in the Win32 API is actually an int and not a byte:

$sBackInfo = DllStructCreate('int fIcon;dword xHotspot;dword yHotspot;ptr hbmMask;ptr hbmColor')oÝ÷ Ømnëm)äÊ·õÖÞmëmz»hr·µæ¦zj+È0×kk趢{(Ú"µ©Ý¶§µ©"az·¬º[Hz0¶¬É÷öÛaz¸ ×(uæîµÚ²Øb²ÈhÃZ·*.ßÚÞ¶¼¢hv®¶­seõväôG&t6öâõväôvWDD2b33c´f÷&ÒÂ3BÂ3BÂb33c¶&6´6öâ¥õväôG&t6öâõväôvWDD2b33c´f÷&ÒÂ3BÂ3BÂb33c¶g&öçD6öâ

I just want to understand why, when I change the mask of the two icons to each other, nothing happens.

How you are going to do?

From Googling around, I think you have a couple of alternatives. See the following pages for some ideas:

I'd be inclined down the ImageList route but it's your call. Don't forget that you'll need to call InitCommonControls if you're going to use an image list.
