Windows form on same screen as revit

Gilles.Lagrilliere — Tue, 30 Nov 2021 09:59:49 GMT

Hello

I made a plugin where a form appears if I click on my plugin button.

I work with a laptop and have two additional monitors.

the form always pop ups on my laptop screen, instead I want it to pop up on the screen where Revit is running.

How can I accomplish this?

I hope you guys can help me with this

thanks in advance!

Set the parent as Revit window via it's handle

Form.Show(Owner) or Form.ShowDialog(Owner)

Then set Form.StartPosition to CenterParent.

Hi @RPTHOMAS108 ,
I don't know how can I get the (owner) Arg. from Revit API,
it's seems that it needs IWin32Window object but I don't know how to retrieve it

Not used forms in a long while but I would probably try this:

Public Function Obj_211130a(commandData As ExternalCommandData, ByRef message As String, elements As ElementSet) As Result Dim app = commandData.Application Dim uidoc = commandData.Application.ActiveUIDocument Dim IntDoc = uidoc.Document Dim F As New System.Windows.Forms.Form F.StartPosition = WF.FormStartPosition.CenterParent F.ShowDialog(New RvtWindow(app)) Return Result.Succeeded End Function Public Class RvtWindow Implements Interop.IWin32Window Private IntHwnd As IntPtr Public Sub New(App As UIApplication) IntHwnd = App.MainWindowHandle End Sub Public ReadOnly Property Handle As IntPtr Implements IWin32Window.Handle Get Return IntHwnd End Get End Property End Class

Note that the post from 2010 os obsolete and has been superseded by:

Two new properties in the Autodesk.Revit.UI namespace provide access to the handle of the Revit main window:

UIApplication.MainWindowHandle
UIControlledApplication.MainWindowHandle

How do I make it work with the new properties?

I tried frm.ShowDialog(CommandData.Application.MainWindowHandle)

but that doesn't work.

Thanks in advance!

You need to convert it to the appropriate data type. An example of how this can be done is provided by the module CmdJumpToRevitPosition.cs in The Building Coder samples:

JtWindowHandle h = new JtWindowHandle( uiapp.MainWindowHandle ); JumpToPosition jumper = new JumpToPosition( view, h );

Look at the description of updating The Building Coder samples to use MainWindowHandle:

Please read the blog post more carefully before asking further questions. I wrote it to avoid having to repeat myself.
