This is very useful and clear.  But how can that same bitmap graphic be placed directly on the GUI (i.e., not on a button)?

I've tried this without success:

$hHBITMAP = _GDIPlus_BitmapCreateFromMemory(Binary($bico), True)
;
$pic = GUICtrlCreatePic("", 130, 130, 32, 32, $BS_BITMAP)
$hPic = GUICtrlGetHandle($pic)
_SendMessage($hPic, $BM_SETIMAGE, 0, $hHBITMAP)
;
_WinAPI_DeleteObject(_SendMessage($hButton, $BM_SETIMAGE, 0, $hHBITMAP))

Thank you UEZ :D

Didn't knew about the _GDIPlus_BitmapCreateFromMemory :sweating: 

 

It is the same function as Load_BMP_From_Mem but integrated as _GDIPlus_BitmapCreateFromMemory now n GDIPlus.au3.

For picture control you have to use this:

Global Const $STM_SETIMAGE = 0x0172
$hHBITMAP = _GDIPlus_BitmapCreateFromMemory(Binary($bico), True)
;
$pic = GUICtrlCreatePic("", 130, 130, 32, 32, $BS_BITMAP)

_WinAPI_DeleteObject(GUICtrlSendMsg($pic, $STM_SETIMAGE, $IMAGE_BITMAP, $hHBITMAP))

Yes, thanks, UEZ!   GUICtrlSendMessage works.

But, is there any short explanation as to why _SendMessage can't send to a Pic, but can to a Button?  What is the basis for having different send messages functions?

I'm only looking for a general understanding to help me navigate this sort of thing.

Well, you can use also _SendMessage() but I'm using mostly GUICtrlSendMsg to send a GDI bitmap to the control.

    If $iReturn >= 0 And $iReturn <= 4 Then Return $aResult[$iReturn]
    Return $aResult
EndFunc   ;==>_SendMessage
#ce
 

But I cannot tell you the difference between _SendMessage and GUICtrlSendMsg because GUICtrlSendMsg is "hidden". Maybe a dev can answer this.

 

I assume it is more or less the same but _SendMessage has some more parameters which can be provided.

Thanks for your reply.

That works equally well.  I looked up 0x0172 and saw that it's the code for $__STM_SETIMAGE.  Then I looked up SETIMAGE on msdn and found that the _SendMessage can set either an icon or a bitmap, depending on whether you provide a BITMAP or ICON image as the parameter.

 

That's about as far as I can afford to look into this right now.  I glad to have another way to use PNGs on GUIs.  But you may be onto something regarding GUICtrlSendMessage as a native function.  It would be nice to know if it's the better choice if the extended params aren't needed.   Or is _SendMessage ("Wrapper for commonly used DLL Call") more efficient if you have the control handle?
