Fix the issue – the history in run command is going away

There was something wrong with my laptop some days ago and I got the loaner machine.  Yesterday when I got my laptop, one interesting thing was that when I entered something in the Run command, it would go away next time. This was not convenient for me.



After looking into this issue, I found it is easy to fix.

Right Click on Start Menu. Click Property.

In Star Menu Tab, Privacy is disabled. Please check 2 as follows.



Click Customize.

Choose size as you like


After that, the history in run command is showing up again.

The Feature Is Back- Visual Studio 2013 Can Run Selected Tests in Test List Editor

On August 29, 2013, I wrote a post mentioning VSTS 2012 IDE update 3 doesn’t really support Coded Web Performance Tests at a time.

After I installed Visual Studio 2013 RTM, I upgraded my Visual Studio 2010 Test Project including VSMDI file. I would like to see if Visual Studio 2013 fixes the issue above.

From the screenshot, I could see Test List Editor is deprecated. This is expected because it has been deprecated since Visual Studio 2012.




Can I run Selected Tests in one of my Test Lists? The answer is yes.

Here are the simple steps:

Select Pending Test lists -> 7 tests are selected.

Go to TEST- Run -> Selected Tests



This feature can only build the solution file because I see “Build succeeds”.

Go to LOAD TEST-> Run -> Selected Tests



It will automatically run 7 tests at a time. This is really what I want.


I am very happy to say that this feature is finally back and it fixes the bad design issue I mention above.

IE10 is not required for Visual Studio 2013 RTM

Many people were complaining about one system requirement of Visual Studio 2013 RC and Visual Studio 2013 Preview: IE 10. I was complaining about it too because many companies still use IE9 or IE8. 

Today I downloaded it and when doing the install, I felt surprised to see the following screenshot. 



It means I can still install Visual Studio 2013 RTM without IE10. But some features might not work as expected. This time Visual Studio Team is listening to people’s voice.  I really appreciate their smart decision.

Just followed the instruction and the install was finished.

Fix the issue: Blank cells in Excel 2010 via Copy with Headers in SQL Server 2008 R2

In this Sprint, we have the important feature: Users uploads the Excel Spreadsheet in our Silverlight Application, 283 values will be saved in the new table in SQL Server 2008 R2 and the values will show up immediately in the Silverlight UI page.

Validating 283 values is really time-consuming. One basic test scenario is that I put the incremental values (1-283) in each cell first and then validate the values are showing up correctly in DB after the upload of spreadsheet.

Each field in the UI has the long business name so I use column aliases in the SQL script.

For example

Select
YR1_SALES_INV_RATIO as ' Market Year 1 Sales to Investment Ratio'     ,
From TableName

In order to validate the values correctly, I use Copy with Headers and paste the data to Excel spreadsheet. Here are the steps:

·         Select the data in SQL Server 2008 R2 and use Copy with Headers

·         Paste to the Excel Spreadsheet 2010

·         Transpose the data

One interesting issue happens after trying to compare the values.  Many header cells after the transpose are blank in Excel Spreadsheet.



I know I can use “Shift cells up” to remove the blank cells, but this is not the best solution because I need to remove them manually every time after doing copy/paste/transpose.


After looking into this interesting issue for a while, I finally find “column Aliases” are too long and Copy with Headers function can’t handle it well in Excel Spreadsheet, which causes the blank cells.  

After simplifying column aliases and try the steps above, the blank cells are going away.

Fix the issue- Missing Option of Connect to Outlook in SharePoint 2010 Team Calendar

Every time when I go to our Project Dashboard, the following JavaScript error appears in IE8.


When I click Team Calendar and try to sync SharePoint 2010 Team Calendar with MS Outlook 2010, the option of “Connect to Outlook” is missing.  It was working fine.  After talking to 2 team members, one has the same issue too, but the other one doesn't.



 After looking into this issue, I learn something as follows:

·         Running sfc /scannow is not useful at all.

·         I use Office 2010, so running Office Diagnostics is not useful because it is for Office 2007 only.

·         There is no owssupp.dll in Office 14 folder (C:\Program Files\Microsoft Office\Office14). We don’t need to register it in the machine.

·         SharePoint Stssync Handler is required to appear in Manage Add-ons. It is missing in my IE. [Main Reason]

How to fix this issue?  It is pretty easy.

Go to Programs and Features-> Right Click Microsoft Office 2010-> Change->  Choose Repair.  

After that, the following issues are fixed.

JavaScript error goes away in Project Dashboard.

The option of “Connect to Outlook” appears in SharePoint 2010.

SharePoint Stssync Handler appears in Manage Add-ons

Using COLLATE Latin1_General_CS_AS can search the right data

Last Friday I found out an interesting issue. The data was not showing up in the Silverlight UI, but the data has the value in the table in SQL Server 2008 R2.

After investigating the issue with our product owner, also a GIS analyst, we finally found out it was the data load issue.

One of the ArcGIS domain values is “Unknown”.  When we do something in the Silverlight UI, the value of “Unknown” is saved in the table. But they used ‘unknown’ to do the data load, which causes the current issue in Silverlight UI.

In order to find out how many rows have “unknown” value, we use the following SQL command because adding COLLATE Latin1_General_CS_AS will not return any “Unknown” data.

select colum1
FROM table
where colum1 COLLATE Latin1_General_CS_AS = 'unknown'

The table has 10, 000+ rows with “unknown” value.  After updating the value from unknown to Unknown, the data is showing up in Silverlight UI perfectly.

Fixed the issue in Oracle SQL Developer - The program can’t start because MSVCR71.dll is missing from your computer

I am working on another project and haven’t touched Oracle SQL Developer for some months. Today when I double clicked sqldeveloper.exe and tried to open it, it showed the following error:

The program can’t start because MSVCR71.dll is missing from your computer. Try reinstalling the program to fix this problem.



After looking into this issue, it is easy to fix it.

Go to Registry Key (regedit)

Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\ sqldeveloper.exe

If you don’t see sqldeveloper.exe, create a new key.

Create a new string and then point to the file location - C:\RayLin\sqldeveloper-3.2.20.09.87\sqldeveloper\jdk\jre\bin



Double click sqldeveloper.exe again and you are all set.

WCF properties are not accessible at compiler time via C# dynamic type

Today I create a simple unit test to get some values from the table in SQL Server 2008 R2. This time I would like to use dynamic type in the code because the values from the table have different data types (int, string, and double). I don’t want to do casting and type conversion.

The interesting part is that when using dynamic type, WCF properties are not accessible, but when using var, they are accessible. That’s because with dynamic, it doesn’t know anything about properties at compiler time. It only knows them at run time.

If I would like to access properties directly, using var is a good idea, but it requires casting and type conversion.

If I don’t like to do casting and type conversion, using dynamic is a good idea, but properties are not accessible. I need to memorize the property names. That’s the trade-off.

Using dynamic is not useful in this unit test.

SQL Query: Transpose Columns to Rows via UNPIVOT

In this sprint, we have new features and I need to validate the data accuracy in our Silverlight Application and some related tables in SQL Server 2008 R2.

A table has 300+ columns

B table has 200+ columns.

The new features of Silverlight application are still in Development and automation is not possible at this moment.

If I would like to validate data accuracy in many columns in the tables, after running SQL query via SSMS, I need to use the scrollbar at the bottom to switch to the right to take a look at the values gradually. That’s not efficient.

One efficient way is to use “copy with headers” to copy the headers & values and past the data into the Excel Spreadsheet. After that, I can compare the values between Silverlight UI and the spreadsheet quickly after using transpose function in Excel. If I can transpose columns to rows in SQL query directly, that’s great too.

The following one is the simple SQL query for me to transpose columns to rows easily via UNPIVOT.

Windows Update Bug about DPI Setting

We have a 55 inch TV that connects to HDMI desktop computer at home. My wife likes to install some TV software to watch TV programs. In order to make the text size larger in those software, she sets DPI = 200%.



However, every time after doing Windows Update and making the computer reboot, the text size becomes so small, but DPI is still 200 %. In the beginning, we thought it was the issue on TV software. After spending some time looking into this issue, she is so smart that she can fix the issue by herself.

Set DPI =100%, click OK and then set DPI=200% again. The text size becomes larger and everything is back to normal.


She talks to me often that she doesn't like Windows Update on this HDMI desktop computer because she needs to reset DPI setting every time. That’s not user-friendly. Who will know it is the issue in DPI setting? I totally agree.

The Useful Diagram of TFS 2010 Upgrade Path

Our team is working on the upgrade from TFS 2010 to TFS 2012. However, our team members were confused about VSTS and TFS per our conversation.

Some said we use VSTS 2010 to develop the current project, but will use VSTS 2012 to develop another project. Therefore, the best way is to upgrade from TFS 2010 to TFS 2012.

To clarify their confusion, I spent some time drawing the diagram of our TFS upgrade path via one note. After our team conversation and this diagram, we are on the same page.

Unit tests in VSTS 2012 update 3 can be still executed successfully via mstest in TFS 2010 build server

Unit tests in VSTS 2012 update 3 can be still executed successfully via mstest in TFS 2010 build server.

Everyone knows that we can’t run all tests via Test List Editor because it is deprecated in VSTS 2012. Test Explorer is new to VSTS 2012, but coded web tests are not supported in Test Explorer (Please see the post of VSTS 2012 IDE update 3 can’t run multiple Coded Wed Performance Tests at a time [only MSTEST Matters])




In our current environment (TFS 2010 Server, TFS 2010 Build Server, TFS 2010 Build Process template), can all tests (WCF tests, DB tests, Coded web tests) after the upgrade to VSTS 2012 be still executed successfully via mstest in TFS 2010 Build Server? Therefore, I would like to try the following basic scenario: 

·         Back up the current VSTS 2010 unit tests (WCF tests, DB tests, Coded web tests) 

·         Upgrade all tests from VSTS 2010 to VSTS 2012 update 3. 

·         After the upgrade, create a new folder in TFS 2010 source control and check in VSTS 2012 code. 

·         Clone a new TFS 2010 build definition from the current one and all configuration will remain the same. 

·         Edit the new TFS 2010 Build Definition for VSTS 2012 code

      --In Workspace, change the working folder to TFS 2012 code
      --In Process, still use TFS 2010 Build process template.
      --In Process, Items to Build and Automated Tests point to the new TFS 2012  Solution file
      --In Process, Test Metadata file will point to VSTS 2012 code



·         Save the build definition 

·         Push a new build


After pushing a new build, all tests in VSTS 2012 Update 3 can be still executed successfully via mstest in TFS 2010 build Server.

TFS 2012 Clone Build Definition

My manager talked to us that he is using another server to upgrade TFS 2010 to TFS 2012 team project where people can use VSTS 2010 or VSTS 2012 team explorer to connect. 

Currently I have VSTS 2010 & 2012 (side by side install) in my laptop. When I use VSTS 2012 to connect to TFS 2012 team project and try to clone a new build definition, I don’t see “Clone Build Definition” function (Please see a post of  TFS 2010 Clone Build Definition)

I don’t feel surprised because I only installed TFS powerful tools 2011 for TFS 2010, which is not supported in TFS 2012.


After I install Visual Studio Team Foundation Server 2012 Update 2 Power Tools, Clone Build Definition appears.


Fixed the issue: HTTP Code 404 not found when connecting to TFS 2010 Team Project via VSTS 2012

After the Labor Day long weekend, I am back to work today. When I used my VSTS 2012 to connect to TFS 2010 Team Project, I got the following error, but it was working last week.


After looking into this issue, I deleted all files in the following folder and everything is back to normal.


C:\Users\username\AppData\Local\Microsoft\Team Foundation\4.0\Cache

VSTS 2012 IDE update 3 can’t run multiple Coded Wed Performance Tests at a time [only MSTEST Matters]

I don’t understand why VSTS 2012 IDE update 3 doesn’t really support Coded Web Performance Tests. Is it because VSTS team doesn’t like web test team? J

After I upgrade my test projects (unit tests, coded web performance tests) from VSTS 2010 to VSTS 2012, it makes me think of still using VSTS 2010.

Per MSDN forum:

  1. VSTS 2012 Test Explorer doesn’t support coded Web performance tests via Test Category. Therefore, I can’t see coded web performance tests appear in Test Explorer [bad design]

  1. I would like to run 10 tests for every environment (DEV, TEST, and Stage) at a time. If I choose load test->run-> selected test, it will run all (30) web tests at a time.  MSDN forum mentions we need to use MSTEST to run 10 tests instead of using VSTS 2012 IDE. You can only use Run Coded Web Performance test for one test. [bad design].





If you are still using Coded Web Performance tests, VSTS 2010 is still the best choice. You can use VSTS 2010 IDE to run multiple coded web performance tests at a time in VSMDI file instead of using MSTEST. The new Test Explorer is not powerful in VSTS 2012.
