The important part is that I need scrollbars if the image is larger than the GUI to draw via GDI+ onto the image.

Nice idea but I need a control id / handle where I can draw via GDI+. It is not only for displaying an image!

UEZ,

The problem is that the toolbar is considered part of the client area and so gets scrolled along with the other controls. All my Googling suggests that the DWM API (in particular DwmExtendFrameIntoClientArea) might be the solution to keeping the toolbar out of the client area - but it seems to be limited to Vista+ and also needs Aero enabled.

I hope this is of some help - personally I think that a child GUI is simpler, and certainly more general in application!

UEZ · May 15, 2012

@M23: thank you very much for your effort. I already implemented what I want with parent/child gui but I don't like the situation that the focus is changing depending which GUI is currently active -> see "Basic Image Editor" in Windows Screenshooter.

There are several applications like screen captures (e.g. Snipping Tool) which are using only one GUI:

Snipping Tool:

>>>> Control <<<<

Class: ToolbarWindow32

Instance: 1

ClassnameNN: ToolbarWindow321

Name:

Advanced (Class): [CLASS:ToolbarWindow32; INSTANCE:1]

>>>> Control <<<<

Class: Microsoft-Windows-Tablet-SnipperEditorPanel

Instance: 1

ClassnameNN: Microsoft-Windows-Tablet-SnipperEditorPanel1

Name:

Advanced (Class): [CLASS:Microsoft-Windows-Tablet-SnipperEditorPanel; INSTANCE:1]

The windows handle stays the same on both controls.

The hint to exclude an area on GUI sounds interesting...

Hello UEZ, someone posted a similar solution in c++ at codeproject. Take a look: http://www.codeproject.com/Articles/3175/Displaying-Bitmap-with-Scrolling

UEZ · May 15, 2012

Nice idea, not scrolling the control but copying a portion from the image to the control according to the scrollbar values.

Thanks,

UEZ

All I could do so far was this:

#include <ButtonConstants.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#include <SendMessage.au3>
Func SetBitmapResourceToPicCtrl($hwnd,$ctrl,$file,$resource)
    Local Const $STM_SETIMAGE = 0x0172
    Local Const $IMAGE_BITMAP = 0
    Local Const $LR_LOADFROMFILE = 0x00000010
    Local $A = ControlGetHandle($hwnd,"",$ctrl)
    Local $DLLinst = DLLCall("kernel32.dll","hwnd","LoadLibrary","str",$file)
    $DLLinst = $DLLinst[0]
    Local $hBitmap = DLLCall("user32.dll","hwnd","LoadImage","hwnd",$DLLinst,"short",$resource, _
            "int",$IMAGE_BITMAP,"int",401,"int",225,"int",0)
    $hBitmap = $hBitmap[0]
    _SendMessage($A,$STM_SETIMAGE,$IMAGE_BITMAP,$hBitmap)
    DLLCall("kernel32.dll","int","FreeLibrary","hwnd",$DLLinst)
EndFunc

$Form1 = GUICreate("Form1", 633, 391, 481, 220)
$Pic1 = GUICtrlCreatePic("", 88, 56, 401, 225, BitOR($SS_NOTIFY,$WS_GROUP,$WS_HSCROLL,$WS_VSCROLL,$WS_CLIPSIBLINGS))
SetBitmapResourceToPicCtrl($Form1, $Pic1, @scriptdir & "IrRes.dll", 97)
GUISetState(@SW_SHOW)
While 1
$nMsg = GUIGetMsg()
Switch $nMsg
Case $GUI_EVENT_CLOSE
Exit
EndSwitch
WEnd

Please, once you finish your example, do post it here. It will be a great help to me... like using WM_HSCROLL and WM_VSCROLL.

rover,

I very nearly PMed you to see if you had a solution. Glad to see my confidence in your abilities was well placed!

@rover: nice example Mr. GUI

That was also one of my ideas to exclude an area of the gui but had no idea how to do it.

Thanks for sharing it!
