Enable Treat Warnings as Errors in TFS Build

Hi ,


Here you go with the settings so that the warning will get treated as error in Team Build(TFS 2010).

Provide below value for the section MSBuild Arguments(See screen shot)

/p:TreatWarningsAsErrors="true"

 

And after that all the warnings would get treated as error J

VS2010 vs. SQL Assistant

Hi guys,


My VS2010, started acting VERY weird! Upon startup, it gave my mysterious errors like “Could not load module this and that”.

And when I tried to open a solution, it just “Stopped working”, asking me if I wanted to debug the program. Yeah right, let me just debug visual studio 


Anyways, I ran devenv.exe with the /log switch, and got a pretty sweet XML file. It pointed me to what errors did occur during startup.


I did a Google search, and stumbled across this one: http://www.softtreetech.com/support/phpBB2/viewtopic.php?p=27786&sid=24857705cf905400d2125e79a4b72565

I realized that I just installed SQL Assistant, and guess what, I did not check the checkbox “ Integrate with Visual Studio 2010”. Just as the above link explains.


One guy at the forum, puts it down this way:


I found a solution. I installed SQL Assist with the the Visual Studio Addin checked, even though I don't want it.

Your installer is telling Visual Studio to load the Addin, even if you don't choose to install it.

Well, that’s what I did as well, and now it’s working.
Thanks,

Unattained Installation of Team Visual Studio 2012

Before we start our Silent Installation of Visual Studio 2012. We have to take care of few as mention below:

1.       IF SOURCE FOLDER CONTAINS SPACE(S) ANYWHERE IN THE ENTIRE PATH, INSTALLATION WILL FAIL.

2.       Create a copy of AdminDeployment.xml (to serve as backup in case any unwanted changes occur in original file)

3.        Change value of attribute NoWeb="default" to NoWeb="yes" in AdminDeployment.xml. See the highlighted section.

ORIGINAL:

http://schemas.microsoft.com/wix/2011/AdminDeployment

">

   NoWeb="default"/>

  

CHANGED:

http://schemas.microsoft.com/wix/2011/AdminDeployment

">

   NoWeb="yes"/>

  

3. Copy CHANGED AdminDeployment.xml into packages sub-folder of SOURCE FOLDER.

Now the below Script will do the magic to installed VS2012 in Silent, Unattained mode.

@echo off

echo ========================================================

set application=Visual Studio 2012 Premium

IF %ERRORLEVEL% == 0 (

                ECHO instalation done SUCCESSFULLY.

) ELSE (

                ECHO instalation FAILED. ERROR LEVEL %ERRORLEVEL%.

Tracker Response files not found (Tracker.exe)

Few Days Back while building one of the project we were getting below error continuously.

On looking in to msdn we finally got the workaround solution for this issue.

Solution:

Edit the build definition (Team Explorer => solution => builds => (select your build definition) right click Edit Build Definition => Process (on left) => 3. Advanced => under MSBuild Arguments paste the following: /p:TrackFileAccess=false from http://social.msdn.microsoft.com/Forums/en-US/tfsbuild/thread/baf16a4b-c25d-4722-a844-6276344b0db2

Here are words from MSBuild Developer from Microsoft.

The trigger for the error is that the GenerateResource task must be run during the build in such a way that we embed FileTracker (a tool we have been using for up-to-date check) in the process itself -- when targeting 4.0, when targeting 3.5 on a 32-bit machine, or when targeting 3.5 on a 64-bit machine when running 64-bit MSBuild. To work around the error, you can either set TrackFileAccess=false, as has already been observed, or if you're on a 64-bit machine and targeting 3.5 exclusively, the error should also go away if you start using 32-bit MSBuild instead. TrackFileAccess=false works around the error by turning off the use of FileTracker; the downside is that that means the you will no longer be able to use FileTracker-based up-to-date check, so your VS 2010 C++ projects and your GenerateResource task invocations will now always build, even when there have been no changes -- the latter generally causing a cascading rebuild for the managed compilers as well, since they consume the .resources files. Thanks, Sara Joiner Developer, MSBuild

NetTcpPortSharing service: failed to start the service

Few Days back when I was running and build, it started throwing an exception as:

The TransportManager failed to listen on the supplied URI using the NetTcpPortSharing service: failed to start the service because it is disabled. An administrator can enable it by running 'sc.exe config NetTcpPortSharing start= demand'.. ---> System.InvalidOperationException: Cannot start service NetTcpPortSharing on computer '.'. ---> System.ComponentModel.Win32Exception: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.

Solution
To enabled, run the following command in console windows as mention in the error log
sc.exe config NetTcpPortSharing start= demand

 

To disable it, run the following command in a console window.
sc.exe config NetTcpPortSharing start= disabled


And after that run you build once again. I'm sure it would not throw any error next time.

Add an Alert on TFS when a build failed or partially succeeded

To get the notification related to your build you have launched the Team Foundation Build Notification tool to have a small popup alert every time a build finishes and starts.

But now you would like to go a bit further and receive a mail with the build result every time a build fails (or let's say do not succeed).

Use the TFS' alerts

The Team Foundation Server includes a powerful alert system, but by default, you cannot do so many things.

Use the Team Foundation Server Power Tools

If the Project Alerts does not allow so many things, the underlying alert system is very powerful. And you can use the Team Foundation Server Power Tools  that allow a very fine control of the alerts.

You can then create a new rule like the following one : 

Note that for the Send To field, you can either indicate an account name, or an email address. In the case of an account name, this corresponds to an AD account, and you must have configured the email address of that person in the Active Directory.

Concept taken from: http://www.pedautreppe.com/post/How-to-add-an-alert-on-TFS-when-a-build-does-not-succeed-.aspx

Build Failed with an error as SGEN: Unable to generate a temporary class (result=1). SGEN: Internal compiler error (0xc00000fd) SGEN: Out of memory

One of the build were continuously failing with an error as

 

But in other hand the same build were getting succeeded on 32 bits Build agent machine.

Then we triggered the same build on our other 62 bits Build agent and we found that all 62 bits build agent are giving the same error while compiling this build.

And finally we came to this conclusion that the versioning of MSBUILD.exe which is creating an issue not the Build agent machine.

It means to run the same build with green we have to trigger the build on 62 bits build agent but force them to take 32 bits MSBuild.exe to run this Build.

To do this we have to perform this.

Edit Build Definition

Processes ->Advance-> MSBuild Platform-> X86.

Custom error reporting in ASP.NET by using C# .NET

The title sound interesting right. So, in this post we are going to discuss about the custom error reporting in ASP.Net application.


                                                    source Code

We are going to use C#.Net code to trap and respond to errors when they occur in the ASP.net or rather I would say in our web application.

To trap the errors occurs we have written a separate class with the name ExceptionLog.cs, and we are using Global.asax to know about the error and trap through our ExceptionLog.cs class file and record the details into text file.

ExceptionLog.cs file:

In the class file we will write our logic to trap the errors occurred in application and logged that error details into text file.

The Log File:

As I had mentioned that the error details would get logged in textile with the name ErrorLog.txt

Global.asax

We will use the benefit of Global.asax to call error trap method on any Application error.

To know more about the Global.asax file you can visit below links:

1. http://en.wikipedia.org/wiki/Global.asax

2. http://msdn.microsoft.com/en-us/library/1xaas8a2(v=vs.71).aspx

3. http://www.dotnetcurry.com/ShowArticle.aspx?ID=126

4. http://support.microsoft.com/kb/306355

So here is the piece of code to catch the error occurred in the application and logged those into text file through our custom error logged class.



Hope it will be useful for you!!

Let's customize Google to show previous searchs by Hitesh Sharma

while going through code project website i show one article published by Hitesh sharma.
which catches my eyes with his nice idea and explanation of the article.
awesome!!
here is little introduction:
Introduction


Usually when I Google something there are a good amount of chances that I'll be googling the same thing again after a few days to recollect whatever I learned last time. So I run Internet Explorer and look into the history if I feel like hitting the search button again with the same keywords as I used last time to get the results I am looking for. This works great but one day I just wondered that why doesn't google shows recently searched text on its page, if it does so it will provide Googlers much ease. Certainly since I can't approach Google with the idea so I decided to customize google for my machine so that it may show me whatever I looked for last few times

you can visit this link to get the more details about the artile.

Let's customize Google to show previous searchs

Google Automation-Automated Testing Search Engine

While I was reading Sep 2011 issue of Automated Software Testing Magazine, but at one page my eye got stuck, where the publisher has partnered with Google to create a software test automation search engine. I tried this and its work great it means gave my all search related to automation.

So here is the word complied for the same magazine.

“The Automated Testing Institute has partnered with Google to create a software test automation search engine. If your are looking for the software test automation information, you will get the best results by using this search engine, because it only searches the sites that matter most to automators. You can also restrict searches to blogs and forum sites."

Script to Get Microsoft Product Installed on your machine with version Number

Few days back I was working on build machine. Or you can say I need to release new build machine installed with some specific software.


To achieve this I wrote few bat file to installed particular software silently.

But to verify this whether that software or application has been installed or not I need to check this through control panel. It was kind of manual process.

So avoid this manual process I came across bat file or VBscript file which will list out the entire Microsoft product with version number installed on that particular machine.

First I will show you the bat file to write the entire product with version list in test file:

echo CompanyName SoftwareInstalled VersionNumber>ListOfMicroSoftware.txt


echo ===========================================>>ListOfMicroSoftware.txt
cscript //nologo D:\Install-Jawed\GetListOfSoft.vbs >>ListOfMicroSoftware.txt
 
 

Now here is the logic written in VBscript file.

On Error Resume Next

Const strComputer = "."
Const HKLM = &H80000002
Const strKeyPath = "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall"
Dim oReg, arrSubKeys, strProduct, strDisplayName, strVersion
Set oReg = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & _
strComputer & "\root\default:StdRegProv")
' Enumerate the subkeys of the Uninstall key
oReg.EnumKey HKLM, strKeyPath, arrSubKeys
For Each strProduct In arrSubKeys
' Get the product's display name
oReg.GetStringValue HKLM, strKeyPath & "\" & strProduct, "DisplayName", strDisplayName
' Process only products whose name contain 'Microsoft'
If InStr(1, strDisplayName, "Microsoft", vbTextCompare) > 0 Then
' Get the product's display version
oReg.GetStringValue HKLM, strKeyPath & "\" & strProduct, "DisplayVersion", strVersion
WScript.Echo strDisplayName &"======"& vbTab &"===========================================" & strVersion
End If
Next



 

Click on bat file and it will generate the text file with all products with version number.

Enable Sound when Breakpoint is hit in Visual Studio 2010

It is really interesting and funny to let Visual studio make sound or give some signal that it hit break point.


So here is the tips to do the same. I have done this in windows 7 machine. Might be for other OS setting would be different.

First look at the below snap shot.

Steps:
1. Go to Control Panel.
2. Click on Hardware and Sound. A different window appears.
3. On new popup window click on Change System sounds. A different pop window would appear, refer above snap shot.
4. Select sound tab and scroll down to Microsoft Visual Studio.
5. Select Break point Hit.
6. Now select your desired sound from Sounds drop down menu.
7. Click on Apply and then ok.

Now you are ready to hear the Hit sound, whenever visual studio would hit the breakpoint.

Happy Debugging.

Thanks,

Md. Jawed

 

Deploy your web application other than default Web Site virtual directory using wix template

The below wix template would create a MSI to deploy your application under different virtual directory. It means it would not create your directory under Default Web Site.


So here is the price of code to do the same.

To know more about Wix you can Google it and you will loads of information of various sites.

Get Assembly Version

Below code would help you get the Assembly version.
This code also stamp the build version in a file where you want to write the build version.
The build version is nothing but versioning provided after building the Project from tfs.
so here the code:
///

/// This method will get the version
///
/// return version of version as string
private static string GetVersion()
{
Assembly assembly = Assembly.GetExecutingAssembly();
FileVersionInfo fileVersionInfo = FileVersionInfo.GetVersionInfo(assembly.Location);
return fileVersionInfo.ProductVersion;
}
