Overview

Visual Studio Integration Toolkit for Microsoft Dynamics GP is a Dexterity integrated software tool which contains an Application Programming Interface (API) that can be called from Visual Studio development system using Visual Basic or Visual C# development languages to integrate with functionality normally only available in Microsoft Dynamics GP via the Dexterity development environment, such as menu navigation and area pages. Build 15 adds a suite of over 260 helper functions.

Build 18 adds the Custom Forms module which allows Developers to create new Dexterity based custom forms. The custom forms are web client compatible and include all standard GP functionality. You can use these custom forms from Visual Studio Tools, Dexterity or GP Power Tools.

Form types available include:

  • Blank Forms
  • Dialog Forms (with 1, 2 or 3 buttons)
  • Setup Forms (with table)
  • Maintenance Forms (with table, matching Lookup, Inquiry form and report)
  • Maintenance Forms with Lines (with tables, matching Lookup, Inquiry form and report)

The toolkit is based on the product previously known as Menus for Visual Studio Tools for Microsoft Dynamics GP. However, to maintain compatibility with existing installations and projects, file and object names have not been changed.

IMPORTANT: The Menus and Helper Functions modules for this subscription product has been provided at no charge for almost 20 years as David Musgrave’s personal gift to the Microsoft Dynamics GP Community. All we ask is that the Customer Contact Details and the software itself is kept up to date. We cannot support old builds with known issues, especially for a product that costs us to develop, support and provide licensing for. From the start of 2027, a small subscription fee will be charged for these base modules (see details).

Visual Studio Integration Toolkit Introduction (direct link)

It contains a Dexterity Chunk and an associated assembly for use with Visual Studio Tools. Also included is full documentation and examples showing how to implement the code for both C# and VB.Net.

    Why would the VSTM_1400 package generate a trusted application issue in an addin for GP 2015?

    An exception occurred while trying to load or initialize the addin located at D:\SQL\PROJ\GP2015\GP2015\Addins\ProjAddIn.dll.

    Solution for that last comment — I found the physical file had a block on it when it was copied from your site to my computer. Unblocking the file did the trick

    Hi David

    Do you have an estimated release date for Visual Studio Integration Toolkit for GP 2016?

    Thanks

    Hi Devesh

    Did you follow the link in the downloads section above. Downloads are available for GP 2010, 2013, 2015 and 2016.

    Please note that registration is required, but there is no charge.

    Hey David,

    With Menus for Visual Studio Tools, I could just include the chunk file and dll in my AddIn installation package so users only had to install a single package. Is this no longer an option and users will need to install Visual Studio Integration Toolkit separate from my add-ins?

    Thanks.

      Hi Derek

      You will need to install Visual Studio Integration Toolkit as it needs to write some registration entries as well. It also has additional files now.

      Sorry for the extra step, but that is how it works now.

      Hi Derek

      Just thinking…. the VSIT installer supports silent install and so you could install without showing it.

      Also, if you pre register the customer’s details with Mekorma, the keys will be automatically installed and the customer will never see the registration.

    Hello David,

    This message is from K-ecommerce(Owner of Azox company)
    We have a package to add some custom menus in GP and we use the Menus for Visual Studio Tools for several years.
    For GP2015 and previous versions, it works well by installing our package with chunk files and dlls. GP users don’t need to install or register the product.
    For this version GP2016, they have this error message: “Visual Studio integration Toolkit is not registered” and when they click on Yes to register the product, GP shows the about window . Here if they click on registration button, GP asks for another product that needs to be installed.

    Questions:
    • Is there a version of Menus for Visual Studio Tools for GP2016 that works without request a registration in each user installation(billable or not)?
    • All users need to install the Visual Studio Integration Toolkit and register its GP company?

    In development mode
    • Where do we need to register it? Is there a way without going in GP to do so? Like when building it with a package? Usually it creates the dll and chunk file directly in Gp, but there doesn’t seem to be a place where you can register the dll.

    Thanks for your answers

      Hi Wilbert

      Menus for Visual Studio Tools was discontinued when I left Microsoft in October 2014. I was able to get the rights to it and re-release it as a Winthrop Product.

      I needed a way to track usage of the product and do plan to add additional functionality which will be charged as an optional module. The registration (and installer) is now part of all current versions.

      The registration is per customer site and free of charge for the core functionality. You just need to install and follow the onscreen instructions.

      You can use the order form on our website (Contact Us page or Partner Portal) to pre-register, then the keys will be retrieved automatically via a web service and the user will not need to enter them. So just organise them before you install and the user will not see anything.

      You can also do a silent install with the installer executable, so that you can distribute without needing extra steps for the user to see.

      You will need the code installed on all workstations.

      For your development systems, you can complete the Partner Signup form and request NFR (Not for Sale) registration for your site name and account number. Also, no keys are needed for the Fabrikam sample company.

      Hopefully, this answers all your questions.

    Thanks for your answer,
    Currently, we are partners and we have a product that uses VSIT. We have customers that will use our product in GP2016

    My questions:
    Do we need to register customers with you before installing.

    Thanks,
    Cordially

  10. WinthropDC's avatar

    Hi Wilbert

    The customer needs to be registered. You can either follow the onscreen instructions after installation. Then let us know the customer so we can associate it with you as partner.

    Or you can use the partner portal order form to register in advance.

    Hi,

    I recently added Visual Studio Integration Toolkit to GP on an onpremise server on a GP that is registered with Mekorma, but I keep getting the error code -17 when I load GP. I know the error is caused by the registration not being there, but it’s there. Afterward, if I close GP and open it back, it work correctly. Trying to reproduce the error again, by closing it back and forth do not always trigger the error.

    We have your product on other server for different client, and this is the first that caused this error randomly.

    Not sure if related but :
    If I go to Mekorma Products Registration and try to close the window via the X, it say :

    An open operation on table “ME_CfgStubs_MSTR” failed accessing SQL data.

    With more info :

    [Microsoft][SQL Server Native Client 11.0][SQL Server]Database ‘LIVE1’ does not exist.

    Also it’s for GP2016.

    Thank you !

      If you are doing Silverlight development for the GP 2015 Web Client and still have the ability to trigger events on and call to Dexterity functions and procedures it should still work. I have never tried it, so let me know how you go.

        Thanks for your time David.

        I am developing some SSRS reports and need to call from forms developed using VSTools. I need call this windows using the menu.
        Form contain datepicker control and default rendering is not working for this control. So I want do the silverlight development. Any alternative is there to call Sliverlight forms from GP interface

        Regards,
        Raj

      • WinthropDC's avatar

        Hi Raj

        I have never worked with Silverlight and so cannot provide any more information.

        As long as you can open your WinForm, VSIT is doing its job.

    Hi David! I recently installed the VS Integration Toolkit on a Dynamics GP 2013 test system I’m building. Everything seemed to be working fine until I went through the registration process. The registration key appeared to download and be applied appropriately, however, the next time I launched GP (and now subsequent times too) I’m getting the following error message…

    An error occurred while loading or initializing an addin. Ask your administrator to check the Windows event log for more details. Dynamics will now close.

    And this is the error I’m receiving in the Application event log…

    An exception occurred while trying to load or initialize the addin located at C:\Program Files (x86)\Microsoft Dynamics\GP2013\Addins\WinthropDC.VisualStudioIntegrationToolkit.dll. Exception Details: System.IO.FileNotFoundException: Could not load file or assembly ‘Application.MenusForVisualStudioTools, Version=12.0.0.0, Culture=neutral, PublicKeyToken=8e4d244f870d4c63’ or one of its dependencies. The system cannot find the file specified. File name: ‘Application.MenusForVisualStudioTools, Version=12.0.0.0, Culture=neutral, PublicKeyToken=8e4d244f870d4c63’ at WinthropDC.VisualStudioIntegrationToolkit.GPAddIn.Initialize() at Microsoft.Dexterity.Bridge.AddinManager.LoadAddin(String name, Type type, Boolean checkPlatformAttribute, Int32 currentDexPlatform) WRN: Assembly binding logging is turned OFF. To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

    Do you have a suggestion on how to remedy this?

    Thank you!

    Hello David,
    I hope you all are doing great and safe. We have installed and registered VST for customer who is on GP2016 but it prompt every day when users start his/her computer. Customer is getting annoyed with it. Please help.

    Thanks much
    Sandip

    • WinthropDC's avatar

      Hi Sandip.

      Please use https://www.winthropdc.com/contact.htm to provide more details. Make sure they are on the latest code and have an internet connection. Please make sure that all workstations have the same build.

      If it is updating the tables and/or registration it is because you have mixed builds. Don’t respond here as blog comments are not the correct location for support.

      Regards

      David
