GUISend/RecvMSG

[mikehunt114]

I'm trying to invoke the BM_GETIMAGE message for a button control. I want to verify the handle to/and or the type of image associated with my button. I'm using the following code:

#include <GUIConstants.au3>
#include <Array.au3>

Opt("GUIOnEventMode", 1)

$myGUI = GUICreate("TEST")
GUISetOnEvent($GUI_EVENT_CLOSE, "Quit")

$button = GUICtrlCreateButton ("my picture button", 10, 10,40,40, $BS_ICON)
GUICtrlSetImage(-1, "shell32.dll", 22)
GUISetState()

Sleep(1000)

$val = GUICtrlSendMsg($button, 0x00F6, $BS_ICON, 0)
MsgBox(0, "", $val)
_ArrayDisplay($val)

While 1
    Sleep(10)
WEnd

Func Quit()
    Exit 0
EndFunc

I've never used "custom" message events before, so I must be doing something wrong. Advice?

Thanks.

Edit: I've tried using both $BS_ICON and $BS_BITMAP as the wParam.

Maybe you should read the command again

Little help:

Global Const $IMAGE_BITMAP = 0
Global Const $IMAGE_ICON = 1
Global Const $BM_GETIMAGE = 0x00F6
...
$val = GUICtrlSendMsg($button, $BM_GETIMAGE, $IMAGE_ICON, 0)
...

Thanks, where did you find the values of IMAGE_ICON/IMAGE_BITMAP?

[Holger]

Local MSDN

You can also use the MSDN library online: http://msdn2.microsoft.com/en-us/library/default.aspx

Then type "BM_GETIMAGE" in the field at left top and enter...

Yes, I browsed MSDN extensively before posting here. Notice my link to the MSDN doc in my first post?

I couldn't find values for those parameters, I ended up using Google to find the value for the BM_GETIMAGE message. Where exactly did you find the values? I want to be able to find things like this for myself.

Thanks!

Just do a Google-search

Ah, ok. That's what I had to do for the message code. Thanks.
