I recently created a new page for my SQL Server Daily Health Check Powershell script download and documentation. I updated the script to version v0.8.2 which refactored the original script into a function to eliminate repeating code and make it easier to customize with additional checks. I will add additional documentation and instructions as I get time.

Using ASP.Net ModalPopupExtenders can improve the user experience, but sometimes introduce some annoying side effects on a Mobile device. On a Mobile device like an iPad, if you have a ModalPopup that has more content than fits the screen, it can require having a scrollbar within the popup. If the main page is also too long for the screen, the main page can have a scroll bar also. The user experience degrades when on an iPad, the user is scrolling down the popup content and they reach the bottom of the popup, continued swiping up to scroll down will then start scrolling the main page down. If the user wants to scroll back up within the popup, they must repeatedly swipe down to first scroll the main page up until the top of the main page is reached at which point the popup content will start scrolling up.
There are a number of search results that “remove the scrollbar” from the main page while the modal popup is open by setting the html and body CSS tags to overflow:hidden, but many mobile devices don’t respect overflow:hidden alone. I found it was also necessary to set position:fixed also. When the popup is closed reset the position to static or inherit and set overflow to auto. I used jQuery to change the CSS tags to hide and show the main page scroll bars.

SAP offers reasonable guidance for creating and publishing the various reports (Webi, pdf, Excel, Crystal Reports) using custom web or windows applications that consume their SAP .Net Development SDK.
Using those tools one can create user friendly applications for managing reports in Infoview, but in some cases you may need an easily customizable process for automating some of those tasks. System administrators everywhere are finding Powershell to be a ideal tool administration and automation.
- SAP Business Objects 3.1 (BOXI 3.1)
- User account running Powershell has appropriate permissions to access the fileshare where the source pdf report is located
- Have account credentials with permissions to read/write files on the Bobj API server
- 32bit Powershell x86 engine
- Server or PC running the Powershell script has the SAP Business Objects .Net SDK installed
# Must use x86 powershell client for BOXI 3.1 dll's
#[CrystalDecisions.Enterprise.SessionMgr] | Get-member
$username = "<cmsUsername>"
$password = "<cmsPassword>"
$cmsname = "<cms-servername>:6400"
$cmsAuthType = "secEnterprise"
$BOServerName = "<Bobj-servername>"
[CrystalDecisions.Enterprise.SessionMgr]$boSessionMgr = New-Object CrystalDecisions.Enterprise.SessionMgr
[CrystalDecisions.Enterprise.EnterpriseSession]$boEnterpriseSession = $boSessionMgr.Logon($username, $password, $cmsname, $cmsAuthType)
[CrystalDecisions.Enterprise.EnterpriseService]$boEnterpriseService = $boEnterpriseSession.GetService("", "Infostore")
$boInfoStore = New-object CrystalDecisions.Enterprise.InfoStore($boEnterpriseService)
$myInfoObjects = $boInfoStore.NewInfoObjectCollection()
$myPluginManager = $boInfoStore.PluginManager
$myPluginInfo = $myPluginManager.GetPluginInfo("CrystalEnterprise.PDF")
$myInfoObject = $myInfoObject = $myInfoObjects.Add($myPluginInfo)
$myPDF = [CrystalDecisions.Enterprise.Desktop.Pdf]$myInfoObject
$myPDF.Title = "DeanPowershelling"
$myPDF.Description = "Dean is testing uploading to Infoview with Powershell"
# clean up
The example above is written for Pdf files, but the syntax for the other document types is very similar. Since this is Powershell, it would be a relatively simple task to convert the above to a Powershell Function that could be used by piping the results of some automation to the function to upload a collection of reports at a time, vs. the one-off approach above.
I initially assumed that because I had BusinessObjects installed on my development environment where I was testing, that I had the appropriate dll’s in the GAC to instantiate the BO objects in Powershell. That lead me down a rabbit hole of troubleshooting where I had difficulty determining if the issues I was having were related to the syntax I was trying to use in Powershell or the lack of the necessary BO assemblies.
I experimented with a combination of copying the dll’s from a working .Net web application to a local folder and using the Powershell Add-Type –path syntax to load the assemblies. I used Telerik JustDecompile to browse the SAP .Net SDK assemblies to make sure I wasn’t missing assemblies.
I downloaded and installed the SAP BusinessObjects .Net Development SDK’s. Some time during the troubleshooting I was successfully using the Powershell Add-Type –AssemblyName syntax, but I must have had the assemblies loaded from previous debugging attempts because after a restart of the development box, the script using Add-Type –AssemblyName to load the assemblies was failing to recognize the CrystalDecisions.Enterprise.SessionMgr which is actually a part of CrystalDecision.Enterprise.Framework which I was not loading in the PS1 script prior to the restart. The [reflection.assembly]:LoadWithPartialName was working with the above referenced assemblies even after a restart.
In order to step though and make sure my assemblies were referenced and loaded correctly, I used the above commented out syntax of BO object piped to the Get-Member commandlet to list the methods and properties on the BO objects:
[CrystalDecisions.Enterprise.SessionMgr] | Get-member
If the methods were listed without error, I knew I had the assembly references correct and the assemblies were loaded.
This is important enough to repeat, make sure if you are using the BOXI 3.1 SDK assemblies, you use an x86 32-bit Powershell engine.

This is the shell of a presentation I created to highlight some Visual Studio extensions that I have found helpful for improving my coding productivity in Visual Studio 2012.
The extensions can be downloaded from NUGET using Tools – Extensions and Updates – Online – Visual Studio Gallery:
- Productivity Power Tools 2012 by Microsoft
- Web Essentials 2012 by Mads Kristensen
Powershell is a powerful scripting shell to do any number of administrative tasks. Below is the introductory level presentation I gave to fwPASS, the Fort Wayne chapter of the Professional Association for SQL Server on 10/23/2012.

My Hyper-V Server 2008R2 lab environment is so stable I rarely fire up the Hyper-V MMC snap-in. The last time I opened it was four months ago when I switched from booting it from a USB stick to booting it from an IDE drive. I opened it today and it gave me the typical “Cannot connect to the RPC service on computer 'Servername'. Make sure your RPC service is running.” error. My quick troubleshooting steps follow:
- I double checked to make sure the IP address and host name were still specified in the \etc\hosts file. It was.
- I attempted to remote into the Hyper-V server directly using Remote Desktop and was met with the “Your password has expired” message. I reset the password, and voila – the Hyper-V manager MMC connected to my server and displayed the current state of my VM’s.
