    msgbox position

    my msgbox comes up over the spot that I want the user to see. How can I do something like

    msgbox.top = 100
    msgbox.left = 200

    Can that be done?

    Cheers all

    Phil

    Re: msgbox position

    not sure whether there is a built-in option for messagebox. but you can just create a new form without any titlebar that emulate a message box. then you can set the form top & left just like normal. when u r ready, just call the form method show.

    of course, if you still want to use msgbox, there is a way, what you need to do is after you call the msgbox, there must be a extra handle in the system, use the FindWindow API to get the window handle for the newly created message box. afterward, call SetWindowPos to set the position of the message box.

    Re: msgbox position

    There is the code to position and/or close msgbox
    Code:
    'module
      ' the max length of a path for the system (usually 260 or there abouts)
      ' this is used to size the buffer string for retrieving the class name of the active window below
      public Const MAX_PATH as Long = 260&
    
      public Const API_FALSE as Long = 0&
       
      ' made up constants for setting our timer
      public Const NV_CLOSEMSGBOX as Long = &H5000&
      public Const NV_MOVEMSGBOX as Long = &H5001&
    
      ' MessageBox() Flags
      public Const MB_ICONQUESTION as Long = &H20&
      public Const MB_TASKMODAL as Long = &H2000&
    
      ' SetWindowPos Flags
      public Const SWP_NOSIZE as Long = &H1&
      public Const SWP_NOZORDER as Long = &H4&
      public Const HWND_TOP as Long = 0&
    
      Type RECT
        Left as Long
        Top as Long
        Right as Long
        Bottom as Long
      End Type
