Displaying thumbnails of files in a GUI

[Eric]

It would be great to have a function who can get and display thumbnails of files in a GUI.

Not only JPG, BMP but PDF, DOC...

Thanks

GUICtrlCreateIcon() works just fine.
Search the forum for possible UDF's in this area.

GUICtrlCreateIcon works fine for icons but not for thumbnails.

[J-Paul Mesnage]

Which API can be used to display thumbnails?

[Eric]

I don't know but i have found a method who works for Windows XP but not for Windows 7.

Local $iIcon

GUICreate("", 128, 128)
$iIcon = GUICtrlCreateIcon("", 0, 48, 48, 32, 32)
_Icon_Set($iIcon, @ScriptFullPath)

GUISetState(@SW_SHOW)

Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE

Func _Icon_Clear($iControlID)
    Local Const $STM_SETIMAGE = 0x0172

    If $iControlID = -1 Then
        $iControlID = _WinAPI_GetDlgCtrlID(GUICtrlGetHandle($iControlID))
    EndIf
    Return GUICtrlSendMsg($iControlID, $STM_SETIMAGE, $IMAGE_ICON, 0)
EndFunc   ;==>_Icon_Clear

Func _Icon_Set($iControlID, $sFilePath) ; Idea initially from Yashied.
    Local Const $STM_SETIMAGE = 0x0172
    Local $hIcon, $tInfo

    If $iControlID = -1 Then
        $iControlID = _WinAPI_GetDlgCtrlID(GUICtrlGetHandle($iControlID))
    EndIf
    $tInfo = DllStructCreate($tagSHFILEINFO)
    _WinAPI_ShellGetFileInfo($sFilePath, BitOR($SHGFI_ICON, $SHGFI_LARGEICON), 0, $tInfo)
    $hIcon = DllStructGetData($tInfo, 'hIcon')
    Return _WinAPI_DestroyIcon(GUICtrlSendMsg($iControlID, $STM_SETIMAGE, $IMAGE_ICON, $hIcon))
EndFunc   ;==>_Icon_Set

The accent is on using UDFs.
