"Of The Bay" Version 2.00

[Patrice Terrier]

This is a GDImage project to emulate the MAC OS X dockbar in Windows VISTA and XP.

It is a rather complex project, however i like the result:



Note: You must use at least a 1280x1024 resolution and your display must run in 32-bit mode.

I did put many tricks in this code, and the most trivial is that there is absolutly no API child controls 

Looking forward for your feedback.



Added:
To close the DockBar and restore the default Windows desktop, select the AERO DockBar and press the ESCAPE key.

Always like your demos Patrice!
16 - 20% on P4 3GHz and GForce 2

[Patrice Terrier]

I have updated the zip file, to further reduce the CPU %.

Now if the mouse is outside of the DockBar or if it is not moving hover it, then CPU % should be close to zero.

Thanks for your feedback.

DockBar project status

- I am able to hide all the desktop icons while the DockBar is visible and restore them once the DockBar is closed.

I am trying to figure the best way to retrieve the existing desktop icons to show them on the Dockbar.
I am not sure if the ExtractIconEx API is the best way to do that (on VISTA some icons are indeed PNG).
If you have any suggestions they are welcomed.

[Patrice Terrier]

Looks like the best solution is to retrieve the Desktop Listview handle, doing that:

vHandle& = FindWindow("Progman", "Program Manager")
vHandle& = FindWindowEx(vHandle&, 0, "SHELLDLL_DefView", "")
vHandle& = FindWindowEx(vHandle&, 0, "SysListView32", "FolderView")

'// Here we display the number of icons shown onto the desktop
msgbox str$(SendMessage(vHandle&, %LVM_GETITEMCOUNT, 0, 0))

The problem now is to retrieve each icon using the %LVM_GETIMAGELIST and to figure which icon match a specific shortcut.lnk ...

Hi Patrice,

example runs fine on AMD Sempron 3400+ @ onboard GeForce6, CPU usage is usually 0% with maximum of 14% when I click on it like mad.

Thanks to those who gave me a feedback.

I am still working on it, and i am learning several "under the hood" things about the desktop.

Example:

Code Select Expand


LOCAL hListView, dwProcessId, hProcess, dwSize, lpData AS DWORD
LOCAL nItemCount AS LONG

hListView = FindWindow("Progman", "Program Manager")
hListView = FindWindowEx(hListView, 0, "SHELLDLL_DefView", "")
hListView = FindWindowEx(hListView, 0, "SysListView32", "FolderView")

CALL GetWindowThreadProcessId(hListView, dwProcessId)
hProcess = OpenProcess(%PROCESS_VM_OPERATION OR %PROCESS_VM_READ OR %PROCESS_VM_WRITE, %FALSE, dwProcessId)
IF hProcess THEN
  '// Compute the size of our reserved memory buffer
  dwSize = sizeof(POINTAPI) + sizeof(LVITEM) + %MAX_PATH * 2

  lpData = VirtualAllocEx(hProcess, BYVAL %NULL, dwSize, %MEM_COMMIT, %PAGE_READWRITE)
  IF lpData THEN
     '// Setup pointers
     LOCAL lpPosition, lpItem, lpText AS LONG  
     lpPosition = lpData
     lpItem = lpData + sizeof(POINTAPI)
     lpText = lpData + sizeof(POINTAPI) + sizeof(LVITEM)

     DIM lvi AS LVITEM
     LOCAL szText AS ASCIIZ * (%MAX_PATH * 2)  ' Allow room for unicode
     LOCAL i AS LONG
     nItemCount = SendMessage(hListView, %LVM_GETITEMCOUNT, 0, 0)
     FOR i = 0 TO nItemCount - 1
         '// Init LVITEM structure and copy it to our reserved memory buffer
         lvi.mask       = %LVIF_TEXT
         lvi.iItem      = i
         lvi.iSubItem   = 0
         lvi.pszText    = lpText
         lvi.cchTextMax = %MAX_PATH * 2
         CALL WriteProcessMemory(hProcess, lpItem, lvi, sizeof(LVITEM), 0)
         '// Get text label and x,y location
         CALL SendMessage(hListView, %LVM_GETITEMTEXT, i, lpItem)
         CALL SendMessage(hListView, %LVM_GETITEMPOSITION, i, lpPosition)
         '// Copy from process memory to local variables
         szText = ""
         CALL ReadProcessMemory(hProcess, lpText, szText, %MAX_PATH * 2, 0)
         LOCAL p AS POINTAPI
         CALL ReadProcessMemory(hProcess, lpPosition, p, SIZEOF(POINTAPI), 0)

         Af$ += str$(p.X)+str$(p.Y) + " " + szText + $CR          
   
     NEXT
   
     '// Freeup memory

I have updated the first post of this thread with version 1.0 of the GDImage AERO DockBar.

[Patrice Terrier]

I found a problem that would not fire the target at the first click, I am working on it...

Added:
I think i have fixed it, the zip file has been updated.

If you want to see what i am doing under the hood to fire the shorcuts, then REM out this part of the code

          '// Hide desktop icons 
          'CALL ShowDesktopIcons(%FALSE)

          CALL ShowWindow(hMain, %SW_SHOW)

          CALL SetTimer(hMain, 1, %TIMER_Speed, %NULL)
          WHILE GetMessage(Msg, %NULL, 0, 0)
                CALL TranslateMessage(Msg)
                CALL DispatchMessage(Msg)
          WEND
          CALL KillTimer(hMain, 1)

          '// Show desktop icons
          'CALL ShowDesktopIcons(%TRUE)

And to understand what i am doing look at FireApplication:

Code Select Expand


SUB FireApplication(BYVAL nItem AS LONG)
    'IF ISFILE(gS(nItem).ShellTo) THEN
    '   LOCAL sShellTo, sCmdLine, sFullPath AS STRING
    '   sShellTo = gS(nItem).ShellTo
    '   sFullPath = gS(nItem).WorkDir
    '   IF LEN(sFullPath) = 0 THEN
    '      sFullPath = RTRIM$(PATHNAME$(PATH, gS(nItem).ShellTo), "\")
    '   ELSE
    '      CALL SetCurrentDirectory((sFullPath))
    '   END IF
    '   CALL ShellExecute(0, "open", (sShellTo), (sCmdLine), (sFullPath), gS(nItem).ShowCmd)
    'END IF
   
'   // Here is the magic part!
    CALL PostMessage (ghListView, 513 , 0, gS(nItem).focusXY) '// WM_LBUTTONDOWN
    CALL PostMessage (ghListView, 514 , 0, gS(nItem).focusXY) '// WM_LBUTTONUP

    CALL PostMessage (ghListView, 515 , 0, gS(nItem).focusXY) '// WM_LBUTTONDBLCLK

END SUB

Version 1.01 with popup menu has been released (ZIP file attached to the first post of this thread).

By the way this version will show you how to create an ownerdrawn popup menu with text and icon bitmap (png).

i have test it and can show nothing on the Dockbar.. only menu with "Close Dockbar" are shown

That's very strange, i just checked it on a computer runing XP SP2 and it works the same than on my VISTA Premium laptop.

Great job, Patrice. Runs fine here on WinXP SP3.
