Keep API dialog on top (Modal)

[fxcastil]

I want to keep the API dialog forms such as (Folder & File Search) . I do not want the user to be able to mouse click inside the AutoCAD window when the from is shown, because this will minimize the dialog box and put it in the taskbar. I have read mant posts about how to do this but I can not keep the dialog form on top. The attached file has examples of how I tried to implement the previous posts.

I use the following in VB executables I run from an ACAD macro:


*** The calling routine

mdlWindow.MakeTopMost Me.hwnd
Me.WindowState = 0


*** In a module I call mdlWindow.bas

Private Declare Function SetWindowPos Lib "user32" _
(ByVal hwnd As Long, _
ByVal hWndInsertAfter As Long, _
ByVal x As Long, y, _
ByVal cx As Long, _
ByVal cy As Long, _
ByVal wFlags As Long) As Long

Private Const HWND_TOPMOST = -1
Private Const HWND_NOTOPMOST = -2
Private Const SWP_NOMOVE = &H2
Private Const SWP_NOSIZE = &H1
Private Const SWP_NOACTIVATE = &H10
Private Const SWP_SHOWWINDOW = &H40
Private Const TOPMOST_FLAGS = SWP_NOMOVE Or SWP_NOSIZE

Public Sub MakeTopMost(Handle As Long)
SetWindowPos Handle, HWND_TOPMOST, 0, 0, 0, 0, TOPMOST_FLAGS
End Sub

Public Sub MakeNormal(Handle As Long)
SetWindowPos Handle, HWND_NOTOPMOST, 0, 0, 0, 0, TOPMOST_FLAGS
End Sub

It will remain stubbornly on top unless you put the minimize button on the
form and click it.

Thanks

Fred,
I do not see an attachment 🙂

I use the following...
In a code module:
Public Const SWP_DRAWFRAME = &H20
Public Const SWP_FRAMECHANGED = &H20
Public Const SWP_HIDEWINDOW = &H80
Public Const SWP_NOACTIVATE = &H10
Public Const SWP_NOCOPYBITS = &H100
Public Const SWP_NOMOVE = &H2
Public Const SWP_NOSIZE = &H1
Public Const SWP_NOREDRAW = &H8
Public Const SWP_NOZORDER = &H4
Public Const SWP_SHOWWINDOW = &H40
Public Const FLAGS = SWP_NOMOVE Or SWP_NOSIZE
Public Const HWND_BOTTOM = 1
Public Const HWND_BROADCAST = &HFFFF&
Public Const HWND_DESKTOP = 0
Public Const HWND_NOTOPMOST = -2
Public Const HWND_TOP = 0
Public Const HWND_TOPMOST = -1

' Used for dealing with Forms
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

Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As Any, ByVal lpWindowName As Any) As Long

Public Function SetTopMostWindow(hwnd As Long, TopMost As Boolean) As Long

If TopMost = True Then
SetTopMostWindow = SetWindowPos(hwnd, HWND_TOPMOST, 0, 0, 0, 0, FLAGS)
Else
SetTopMostWindow = SetWindowPos(hwnd, HWND_NOTOPMOST, 0, 0, 0, 0, FLAGS)
End If

End Function

And then in the Form's Initialize Event:
Dim retVal As Long
Dim hwndForm As Long

hwndForm = FindWindow(0&, UserForm1.Caption)
retVal = SetTopMostWindow(hwndForm, True)

Thanks :)...I caught that after re-reading posts...

no editing of posts it seems 😞

cmd,

The example you gave me uses the userform handle as the argument when calling the function for the setting the top most window. The example in my original post is not a VBA useform but an API dialog box. This is where I am having problems I have tried different methods of getting the dialog box handle and then passing this to the topmost function but still no sucess. I would really appreciate if someone could fix the sample file in my original post so I can actually this this implemented . I have tried all the suggestions given to me but I still can not get it right


Thanks,

Fred

Setting BrwsInfo.howner = AutoCAD.hwnd should work, At least id did in
WindowsXP and Autocad 2006

Jose,

Thanks a bunch that was the trick. Unfortunately not a lot of information on the API function properties is available. I used the function
Declare Function GetActiveWindow Lib "user32" () As Long

to get the active AutoCAD.hwnd , this was an easy fix knowledge is wonderful thing.
