Implementing the Microsoft Dynamics GP Web Client–Book Review

Implementing the Microsoft Dynamics GP Web ClientERP systems are migrating to the near zero deployment of web browser delivery and consumption. With Microsoft’s release of the GP Web Client, Dynamics GP is now no exception. Ian Grieve has produced a book that brings lucidity to the process of installing and configuring the GP Web Client and server.

Ian is a figure well known in the Dynamics GP community and has been recognised as such by the awarding of Microsoft MVP (Most Valuable Professional) status. In this book Ian imparts his wealth of experience and disseminates the knowledge he has brought back from the field, where he is working as a busy Dynamics consultant. In his role he has been exposed to an assortment of company requirements and environments that has helped shape this book.

I read the book whilst preparing for my first web deployment. I was grateful for the help with the daunting, multifaceted nature of a Dynamics GP Web Client and server install. The book is excellent for the impatient or time pressed professional needing to get up to speed quickly with this new member of the Dynamics GP system. The pages provide a well-lit path through the process of getting to a functional GP Web Client and server install, quickly and without having to wade though manuals and online guides.

The structure of Ian’s book breaks the system down, addressing each part separately, in a step by step manner. It is rich in supporting screen shots, providing continuous reassurance at each step, feeling much like a colleague has provided you with a much toiled over build script. Although it is valuable to the configuration and installation of the GP Web Client, the book may also facilitate

in comprehending an overview of the install for system administrators too.

Subjects covered also include those important to the end user such as integration with Microsoft Office applications and SQL Server Reporting Services through Silverlight. The limitations of the Web Client are also covered together security set ups. I must praise the inclusion of a troubleshooting section, inevitably needed in any complex server system for configuration and on-going reference.

Dynamics GP is a little sparse in supporting professional grade technical literature, it is good that Ian has written this solid guide to help address that shortage.

Team Foundation Server (TFS) -The underlying connection was closed

image
Having build and upgraded Team Foundation server from 2010 to 2013, SQL Sever and Sharpoint Foundation 2013, running on VMWare ESX,  the team found very frequent and random like connection dropped problems, most frequent being:
  • connection that was expected to be kept alive was closed
  • The underlying connection was closed

This happened trying to check things in, or other source tracking related activities against Team Foundation Server.

The hunt was on the the cause, a week of investigation (on and off), heading off looking at the IIS settings, checking settings for WCF, looking for possible max connection limits, working pools and recycling logs etc.

Also investigated a post regarding network interface card (NIC) off loading and to switch it off on virtual boxes (I’m not convinced by that).

Solution

For others in a similar position, I present our solution, the static IP address that was assigned to the server had accidentally had a a printer assigned to it too. So whenever the user came in to work and put the printer on (not every day), we would experience these problems, for a bit, until the printer went off again. All due to the duplicate IP address.

How to make GP company login text boxes longer

In the blog post series by David Musgrave, he shows how to customise the GP company login boxes, to make them long enough to see very long company names in full. David uses Dexterity in the third part of the series. However in the latest he attempts to do the same using an addin, albeit he “cheats” by passing in the SanScript. Note this is not a supported method.
By using the Continuum COM library to allow .NET code in the Dynamics GP Visual Studio addin to pass SanScript through to the GP we CAN do it, see how I did it!

Customising the Company Login window series Part 4 - Visual Studio Toolsby David Musgrave

So David had a problem getting it working, I had Visual Studio open on my Addin project, so I gave it a go.

Make a reference to the Continuum

This is a COM object in, so go to your project reference and search for “contin” and then add the reference. Ensure you marry the version number with the version of GP you are using.

Store the script in a project resource

Under the project settings, you can store resources. This is a good place to put your scripts as it deals with line feeds and keeps them in an intact form for future editing.

Go to the resources tab of the project properties, create a new resource and paste in the script provided by David. We are going to use the .NET code to run the script, so we don’t need to put it in a procedure, only take the fragment that does the deed. Name the resource LoginResizeScript

Add event handler

Now when the company login window is opened we want to execute the script to resize the text boxes on that window. So to me it seems like a good plan to add and event handler to the company switch form. Now go to your GPAddin.vb and add and event handler like this for the company switch form.

Sub Initialize() Implements IDexterityAddIn.Initialize
'You should add code to only execute once in lifetime
AddHandler Microsoft.Dexterity.Applications.DynamicsDictionary.OpenSwitchCompanyFormProcedure._Instance.InvokeAfterOriginal, AddressOf DoLoginResize

End Sub

Deal with the namespaces

Important as the project reference messes you up!

Imports DynamicsGP = Microsoft.Dexterity.Applications.Dynamics

Execute the script

So next the script needs to run in response to the event firing on the Switch Company event handler. Add the following to your GPAddin.vb .

The SanScript is now held in a project resource we can reference by My.Resources.Resources.LoginResizeScript so we push this into the ExecuteSanscript method.

Public Sub DoLoginResize(sender As Object, e As EventArgs)
Dim CompilerApp As New Dynamics.Application
Dim CompilerMessage As String = Nothing
Dim CompilerError As Integer
' Execute SanScript in Dynamics GP
CompilerError = CompilerApp.ExecuteSanscript(My.Resources.Resources.LoginResizeScript, CompilerMessage)
If CompilerError <> 0 Then
Windows.Forms.MessageBox.Show(CompilerMessage)
End If
End Sub

Resulting resized controls – it works!

And hey it works from VB.NET too! I love Visual Studio and Dynamics GP!

“The Installation of this package failed” Sharepoint 2013 Server 2012 R2

On attempting to install team foundation server I encountered the following error trying to install sharepoint 2013 foundation.

image

This was after the installation had failed and on trying to run the installer again.

To clear this dialog box and run the installer again I used filemon to see where the extracted installer was running from and deleted that directory, in my case:

c:\program Files (x86)\MSECache\SharePoint2010

image

The original problem was the pre-requisites could not be downloaded by the installer, due to IE protection mode.
