How to search the file name in Temporary Internet Files folder in C#?

Yesterday, I tried to validate one scenario: if users launch Silverlight UI, how much time does it take to download the files (1 xap file and 19 zip files) in their Temporary Internet Files folder?

Temporary Internet Files folder is the virtual folder. The .xap file is not really inside that folder.

From the command prompt, I can know what the file path is for my Sprint2.xap. It has 2 sub folders. Besides, zip files are not in the same sub folder.

..\Microsoft\Windows\Temporary Internet Files\Content.IE5\L0BLXHLN\Sprint2[1].xap (2 sub folders)

In this situation, how do I search the file names in Temporary Internet Files folder in C#?

After doing some research, I can use the following code easily to get any file name I want in Temporary Internet Files folder.

string filePath = Environment.GetFolderPath(Environment.SpecialFolder.InternetCache);

var files = Directory.GetFiles(filePath, "filename*”, SearchOption.AllDirectories); //filename=Sprint2

If I can validate all files are in in Temporary Internet Files, it means I download them from our server successfully.

VSTS 2010 Web Performance Test- Currently browser extensions are disabled in Internet Explorer

I have used Visual Studio 2010 Web Performance Test to record many tests on my local machine without any issue. Today when I logged in to another Server (Windows Server 2008 R2, VSTS2010 SP1) in the office and tried to record some web tests, the following error appeared.

Currently browser extensions are disabled in Internet Explorer. This Prevents the Web Test Recorder from starting automatically, and from recording some JavaScript and AJAX requests….

I validated that my browser extensions were enabled and security setting was also working as expected. After some investigation, it was easy for me to record the web test.

Just press alt key and the menu bar appears.

Click View->Explorer Bars->Web Test Recorder 10.0 and you can still record the test.

First Try- TeamCompanion in MS Outlook

I have used Team Foundation Server since 2007. Yesterday I saw a tool called TeamCompanion ( 90 day trial) online. After I installed this software in my local machine, it appeared in my MS outlook. Now I can use it to connect to our team project and create work items easily.

When opening my outlook, I can go to our Project Portal to see the work status. For our business members who don’t have Visual Studio IDE installed and always use MS outlook all the time, this is a great tool for them to create work items (bugs, tasks, user story) easily in their MS outlooks directly.

Every time when I search the work item in my outlook, I need to enter the parameter and run the query again. There is no way for me to create a query and save it in the outlook. It is only saved in team project. This is not good for business members.

If they can support this feature, that would be great.

VSTS Web Performance Test: Fix the issue of Request failed: The request was aborted: Could not create SSL/TLS secure channel

Today my colleague told me if I can use VSTS 2010 to automate MicroStrategy 9 BI Web Portal over https protocol because he wants to run BVTs every day.

I tried 2 different ways:

Coded UI Test:

It can be automated without any issue. You need to logout first before you run the test again.

Web Performance Test:

After recording the test, it shows the error: Request failed: The request was aborted: Could not create SSL/TLS secure channel.

After spending some time investigating this issue, I need to add the following source code to let the test pass.

ServicePointManager.Expect100Continue = true;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3; 

In this case, Coded UI Test is the best solution for MicroStrategy 9 BI Web Portal.

VSTS 2010: Add Config Transforms is disabled

Today I look at our developer’s Silverlight Project to debug the issue in Test Environment, and "Add Config Transforms" is disabled when I right click on Web.config .

In order to make Add Config Transforms enabled, I need to go to Build -> Configuration Manager->Active Solution Configuration->New and create a new solution configuration.

After that, Add Config Transforms is enabled.

How to turn on Temporary Internet Files Folder in Windows 7?

Yesterday I wrote the post about Silverlight .xap needs to be updated in the users’ laptops after pushing a new build. Someone asked me where “Temporary Internet Files” folder is. Good question. It is invisible by default, but you can use the command line to open the folder directly.

Here are the steps:

Click Start.

In Search Program and files, enter Folder and Folder Options appears

Click Folder Options. In View tab, uncheck “Hide Protected Operating Systems (Recommended)”. Click Apply.

“Temporary Internet Files “Folder will appear.

Silverlight .xap needs to be updated in the users’ laptops after pushing a new build

We have pushed so many builds including important bug fixes since July 6. Today our business analysts opened their IE and found out why the bugs were not resolved. I talked to them: Please refresh your IE and make sure if you get the latest .xap file in your laptop.

The interesting part of Silverlight UI is that if users keep their IE open, after we push a new build and they don’t feel that, they can still use the old Silverlight UI. In order to make their individual .xap updated, the best way is to use F12 key to refresh IE, clear browser cache and go to the site again. I showed them how to do it. 

I also talked to them: Please make sure if you can see Silverlight loading progress indicator (1%-100%) every time when you launch IE. This indicates the latest .xap is loaded in your laptop. If not, the .xap might not be updated.



We can also use the following way to see if .xap is updated in our laptop.

Go to %USERPROFILE%\AppData\Local\Microsoft\Windows\Temporary Internet Files\ and you will see sprint2.xap.

Last Modified: It is the time we have the new build (e.g. 7/11/2002 11:24 AM).

Last Accessed and Last Checked: It is the time we access the site (e.g. 7/11/2002 11:43 AM)

 

If your .xap is not updated, please use F12 key to refresh IE, clear browser cache and go to the site again. When Silverlight loading progress indicator appears, everything is working as expected later.

System Restore fixes Internet Explorer has stopped responding

Internet Explorer 8 on my work laptop (Windows 7 x64) crashed all the time yesterday when I browsed my Gmail and some sites I visited often. “Internet Explorer has stopped responding” dialog box appeared all the time. I tried the following ways and could not make Internet Explorer 8 work.

Disabling Add-Ons in Internet Explorer 8 didn’t work.

Resetting Internet Explorer 8 didn’t work.

Using sfc /scannow didn’t work.

When looking at the event logs, I saw 2 dlls (mshtml.dll and urlmon.dll) might crash.
  

Using regsvr32 urlmon.dll didn’t work.

Using regsvr32 mshtml.dll didn’t work.

After long investigation, I find our company pushed windows update yesterday and many machines had the issue. After doing system restore, Internet Explorer 8 works perfectly.

How to fix the scenario of No tests to execute via MSTEST in TFS build log?

On June 13, 2012, I wrote a post about How to fix the scenario of No tests to execute via MSTEST in TFS Build 2010?  But I forgot to mention another important thing. You might find this post helpful to you if you have the same issue.

On June 12, 2012, I created a test project that contains unit tests and web tests.  In Visual Studio 2010, I created a new test list called BVT and put all of the tests in BVT and then I checked in the code to TFS source control. After I kicked off a new build in TFS, the build succeeded, but all of the tests in BVT never got executed in the build log (No Tests to execute.)

I logged in to the build server and opened the .sln file of my test project. The interesting part was that all of the tests in BVT were not enabled. I needed to manually click refresh in the test list editor to make them enabled. How did I make those tests enabled in BVT Test List without clicking refresh manually? 

After long investigation , I must check in the bin folder and can’t check in the obj folder. This is  very important!  If I put more tests in BVT, I need to check in bin folder again to make those tests changed. 

After I kicked off a new build again, all tests passed in the build log. After logging to the build server again, all tests were enabled in BVT Test List as well.

Coded UI tests have the huge limitation for Silverlight Application and cross browser testing

For Silverlight 5 Application, Coded UI test is not supported in Visual Studio 2010, Visual Studio 11 and Visual Studio 2012 RC.

For Silverlight 4 Application in Firefox, Coded UI test is only supported in Firefox 3.5 and 3.6.  For higher version of Firefox, it is not supported.

For Silverlight Application in Chrome, Coded UI test is not supported.

For Silverlight Application in Safari, Silverlight is never supported on Windows platform. It is only supported on Mac OS. However, Coded UI test is not supported for Safari.

 As a SDET, I would like to say this is not good news for Coded UI test because it has the huge limitation for Silverlight Application and cross browser testing.

Telerik Test Studio can handle Silverlight 5 Application in different browser easily.
