I use your wonderful add-in sometimes ago and create there projects in VB.Net. Thank you !
Just now i install your template to new PC and there i can find only C# project in start menu

Now VB.Net projects don't supperted in your template or just missed ?

• Generate a new default VB project
• Change framework version to 4.7
• The project does not build (gives compile errors)

Need to update HKLM key in WIX installer in case of per-machine install and Visio 2007

Now the addin's .dll.config file is not included by default in the setup project. It should be.

If you select target platform of the add-in to X64, link (wix setup build) crashes with the following message:

Build started...
------ Build started: Project: Setup, Configuration: Debug x86 ------
light.exe(0,0): error LGHT6509: Visio WiX Extension Internal Error. In case you see that please report the issue to [email protected].
Done building project "Setup.wixproj" -- FAILED.

Workaround: set targe platform to AnyCPU (this is the default, btw)

The extension itself has been updated

But update on the marketplace fails for some reason:

Starting point:

• Created two new Extended Visio Addin Projects:
  1. WixUI_Advanced
  2. WixUI_Minimal
• Both with option "Create new (sample) template and stencil file"
• Did not touch the other options, did not modify the projects.
• Build (Addin)
• Build (Setup)
• Removed all Addins from Visio (registered by build process)

Results:

• Installed WixUI_Advanced only for me: only Addin registered, Template and stencil file not
• Deinstalled
• Installed WixUI_Advanced for all Users: Addin registered, Template and stencil file registered -> Perfect
• Deinstalled
• Installed WixUI_Minimal: Nothing registered
• Deinstalled

Software versions:

• Visio 2019 Professional 64bit
• Visual Studio Community 2019 Version 16.8.4
• WiX Toolset v3.11.2
• Windows 10 Pro Version 10.0.18363 Build 18363

Meanwhile I also tested "WixUI_InstallDir".
-> Addin and Stencil / Template files are not registered.

Hi,

When trying the panel on a multiple document window Visio instance (see image) or with multiple displays, the panel doesn't expand properly. I'm guessing that it has something to do with the CreateWindow() implementation in the PanelFrame class. I've tried to set the nTop and nLeft arguments of the Windows.Add() method to the size of the Visio document window, which does seem to help a bit. It now works properly on both displays with a single document window, but I'm still struggling to get it to work for multiple document windows in a single Visio instance. The problem is that I can't seem to figure out what determines the amount of space the panel is allowed to consume. Are you able to reproduce this issue, and do you have any ideas on how we can improve this behavior?

I do want to mention that I've modified your implementation so that it works with WPF instead of Windows Forms, but from what I've seen in my tests, switching to Windows Forms doesn't change the behavior described above.

It is possible to support these frameworks.

Since .net 5 is the only framework that will be in the future, would make sense to migrate.
