qwert Posted March 28, 2015 Posted March 28, 2015 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))
UEZ Posted March 28, 2015 Posted March 28, 2015 (edited) Thank you UEZ Didn't knew about the _GDIPlus_BitmapCreateFromMemory It is the same function as Load_BMP_From_Mem but integrated as _GDIPlus_BitmapCreateFromMemory now n GDIPlus.au3.

qwert Posted March 28, 2015 Posted March 28, 2015 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.
UEZ Posted March 28, 2015 Posted March 28, 2015 (edited) Well, you can use also _SendMessage() but I'm using mostly GUICtrlSendMsg to send a GDI bitmap to the control. expandcollapse popup#include <GDIPlus.au3> #include <Memory.au3> #include <WindowsConstants.au3> #NoTrayIcon Global Const $STM_SETIMAGE = 0x0172, $BM_SETIMAGE = 0xF7, $BS_BITMAP = 0x0080 Global $bico = "0x89504E470D0A1A0A0000000D49484452000000100000001008060000001FF3FF61000000017352474200AECE1CE" & _ "90000000467414D410000B18F0BFC6105000000E249444154384F9D93B11183300C45198559E8E92929188B9E31684241E58" & _ "CC0064E1A5AC74F67F9841B82B9D321E4AF6759C84D533CE7798ED1D668A1306263A9CFDF71B18DE634E9388ED0759D18BE81" & _ "A1692FA094EC976509FBBE8B185F01F33C4B8C35E2D1F717083BDB84699A42DFF719804F4C8109E2A48A7466A1ABE0EEAD554" & _ "A4F6CC3741776DC5E5BF8F8AF18BE5684C6F46305204DE29C2AD264E7DE01530895A141AB8D1540593209246A5C21A58EDC47" & _ "8061182E9B6500E5D0D97F8F80D61E214F5D6D1319DDFADF9866A17E9012807B503FCA06527799ECCD7A7A9D7F919E81F9F48" & _ "210970000000049454E44AE426082" _GDIPlus_Startup() $Form1 = GUICreate("Example", 300, 200, -1, -1, BitOR($WS_THICKFRAME,$WS_SYSMENU)) $btn = GUICtrlCreateButton("",130,70,32,32,$BS_BITMAP) $hButton = GUICtrlGetHandle($btn) $hHBITMAP = _GDIPlus_BitmapCreateFromMemory(Binary($bico), True) _WinAPI_DeleteObject(_SendMessage($hButton, $BM_SETIMAGE, 0, $hHBITMAP)) $pic = GUICtrlCreatePic("",90,78,16,16,$BS_BITMAP) $hPic = GUICtrlGetHandle($pic) _WinAPI_DeleteObject(_SendMessage($hPic, 0x0172, 0, $hHBITMAP)) _GDIPlus_Shutdown() GUISetState() While 1 $nMsg = GUIGetMsg() Switch $nMsg Case -3 GUIDelete() _WinAPI_DeleteObject($hHBITMAP) Exit EndSwitch WEnd #cs GUICtrlSendMsg ( controlID, msg , wParam, lParam ) Func _SendMessage($hWnd, $iMsg, $wParam = 0, $lParam = 0, $iReturn = 0, $wParamType = "wparam", $lParamType = "lparam", $sReturnType = "lresult") Local $aResult = DllCall("user32.dll", $sReturnType, "SendMessageW", "hwnd", $hWnd, "uint", $iMsg, $wParamType, $wParam, $lParamType, $lParam) If @error Then Return SetError(@error, @extended, "") 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".

qwert Posted March 28, 2015 Posted March 28, 2015 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?
