Modal forms with Taskbar=1

Hi All,

I have a problem with AutoCAD 2005 that my modal forms running from a VB6
Dll project go behind the current AutoCAD drawing window when the new
"TASKBAR" setting is set to 1.
When "TASKBAR" is set to 0 then the form is modal to the current drawing.

Earlier versions of AutoCAD do not have the problem as putting the open
drawings on the taskbar is a new 2005 feature.

Has anyone else had this problem and if so what is the solution?

Thanks.

Olaf

 

Are you sure you don't mean MODELESS forms (the kind
that can remain visible while the user issues commands
in AutoCAD)?

 

Hi Tony,

No I do mean modal. My form has focus and AutoCAD cannot be accessed while
my form is running but it disappears when more than 1 drawing is open with
TASKBAR=1

My forms are all called with form.show vbmodal

If you press Alt-Esc very quickly you sometimes get it to come on top of the
open drawing
I have tried form.show vbsystemmodal but that is an invalid call.

Its a hack but you could always force your form OnTop:

Private Declare Function SetWindowPos Lib "user32" _
(ByVal hWnd As Long, ByVal hWndInsertAfter As Long, _
ByVal X As Long, ByVal Y As Long, ByVal cx As Long, _
ByVal cy As Long, ByVal wFlags As Long) As Long
Private Const SWP_NOMOVE = 2
Private Const SWP_NOSIZE = 1
Private Const FLAGS = SWP_NOMOVE Or SWP_NOSIZE
Private Const HWND_TOPMOST = -1
Private Const HWND_NOTOPMOST = -2

Private Sub SetOnTop(hWnd As Long, OnTop As Boolean)
Dim iReturn As Integer
iReturn = IIf(OnTop = True, _
SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, FLAGS), _
SetWindowPos(hWnd, HWND_NOTOPMOST, 0, 0, 0, 0, FLAGS))
End Sub

Then call SetOnTop when your form loads

Hi Mike,

I have already tried this and it does put it on top of all windows but when
you drag the form around the screen it leaves copies of the form all over
the screen.

I think it is something Autodesk have not thought of when the taskbar option
was introduced in 2005

Hi Olaf,

If you're getting screen smears, that's either a memory or graphics driver
issue - or XP =) While there are definite issues with the taskbar, I
wouldn't attribute it to this.
