Block Revit while Windows Form is running

[franjavigarciavalencia]

Hello,

I would like to block the use of Revit while my plugin runs a certain functionality (in this case, it opens a Windows Form, and I want Revit to be unusable while that Form is open) just like when you want to modify the visibility of a view and it won't allow you to do anything else until you finished any modification.

Is there any method to do this directly?

Thank you.

Hi @franjavigarciavalencia. I always thought that if you use System.Windows.Forms after Form.ShowDialog() Revit becomes unusable. All my forms work this way…

Hi @franjavigarciavalencia ,

Understand the difference between modal dialog and modeless dialog.

Dialog Guidelines 

Create a modal dialog to block Revit while Form is running.

I fully agree with Pavel and Naveen.

If your external Windows functionality is in a separate application, you could still block Revit by launching an external command presenting a modal Windows form, blocking Revit, and use the Windows API or .NET libraries to send a message to close that form and terminate the external command once your external application has done its dirty deed.

I see, I thought it was something related to the Revit UI and not to Forms itself.

Thank you all for your help!
