Use shortcut key to generate GUID very quickly in Visual Studio

One of the common tasks involved in the development is GUID’s generation. This is even more frequent when we are working on a SharePoint solutions.  Even during writing unit test we need to imagegenerate  static GUID to validate data’s. Visual Studio comes with a tool called guidgen.exe  ( c:\program files (x86)\microsoft sdks\windows\v7.0a\bin\NETFX 4.0 Tools\guidgen.exe ) which is registered with visual studio as an external tool and invoked from Tools > Create GUID. But whenever you need an unique static GUID you have to navigate to tool and copy the ID evertime. Last few days of my development involved with lots of GUID generation where I found it’s taking time to generate so many guid’s. So, I came up with an small approach  where we can generate a GUID by  just pressing some shortcut key. Behind the seen I wrote a macro for the same and  that is being triggered with the key press.

Exception Occurred ? – Get Troubleshooting tips from your favorite blogs

In this blog post, I am going to share a quite interesting tips, where you can customize the “Exception Assistant” in visual studio.  I have explained how we can use this features for an custom exception class, where we want to provides custom or additional help information . As an example, I have shown how we can set some favorite blogs urls in troubleshooting tips section.

Video Webcast: 10 Tips you should know about “Watch Window” While debugging in Visual Studio

Few months back I have published an article on 10 Tips you should know about “Watch Window” While debugging in Visual Studio , where I have explained about 10 useful tips on watch window. Here I am sharing you the quick video webcast on that.

Add document header for files automatically in Visual Studio

In this blog post I am going to share  how you can add a document header imageof xml comments with code file automatically. This is going to be an very interesting and helpful for all of you who are using styleCop to maintain coding standard. Actually extensive using of StyleCop helped me to think to make it automate. There are many tools available which can helps us in this case to do this automatically. But I always prefer let’s Visual studio do the job for me.  Here I am going to share with  you two different approaches to deal with this issue. Now it’s up to you which one to use.

Tips : Set Breakpoint to multiple Functions at a same time in Visual Studio

Visual Studio having great features to set breakpoint in  multiple functions at same time.  For most of the time, to set a breakpoint  with in a function you just put a breakpoint in the first line of the function.  Now, assume you have 10 different overloaded methods or you have same function in different project, and you want to put breakpoint all of them or few of them, then it will take time to put breakpoint in each and every function.  In this post I am going to share two quick tips by which you can set breakpoint to function very easily. first one is by using “Break at Function” and second one by “Using Find Combo Box”.

Use Shortcut or Context Menu for “Open Containing Folder” in Visual Studio

Open Containing Folder” is one of  the frequent used functionality to open a particular file location  in windows explore from Visual Studio IDE . How did we do that ? Yes it’s very simple, Just right click on file from files Tab and select “Open Containing Folder” from the context menu as shown in below.

This will open the selected item location in windows explorer. This operation by default having no keyboard shortcut. But do you know we can assign keyboard shortcut for the same or even we can customize the context menu in code editor to achieve the same as shown in below images.

Multipurpose Find Combo Box in Visual Studio

Most of the time we use Visual Studio find combo box (6 ) only for search contents with in the solution. But the find combo box is something more than what we  know. We can use the find combo box in different purpose like create file, open files, create project, print, open watch windows etc. As for example you can close all the open files by just typing  “>CloseAll”  with in find combo box followed by a  “Enter”.  Fundamentally we can execute all the commands from Find Combo box which are available from Visual Studio Command Window. Like Command Window,  In Combo Box, if you type “>” and aliases and press enter result will be the same.

10 Tips you should know about “Watch Window” While debugging in Visual Studio

Watch windows is one of most commonly used debugging tool with Visual Studio. We generally used to explore the objects, values, properties and other nested objects as a tree structure. Most of the time we used watch window to only view the values or change the current object properties values to see the effects of changed object during debugging. But we can use watch windows for many different  purposes. In this blog post I am going to show 10 Tips, that may help you while dealing with Watch Window. 

How to track an object which is Out of Scope while Debugging ?

In Mastering in Visual Studio 2010 Debugging article I have discussed about the basic of Object ID creation while debugging. I received some request from some readers to explain the use of “Make Object ID” in details. In this blog post I am going explain how we can track an Object which is already out of scope using by creating a Object ID while debugging.

By using “Make Object ID” option we are informing Visual Studio Debugger to keep track of that object no matter it’s within scope or out of scope for the current context.  We can create “Object ID” either from Locals, Autos or from Watch Windows. Object ID is a integer number followed by a pound (#) sign. When we create Object ID for an particular object, Visual Studio Debugger ( CLR Debugging Services )  use an integer value to uniquely identify the object. This “Object ID” allows you to get the object details even if it is out of scope.

Tips on Debugging : Using DebuggerStepThrough attribute

In my few previous blog post I have explained  how we can customize the Debugging windows view during debugging of application using “DebuggerBrowseable “  attributes and “DebuggerDisplay” , then I have also explained use of “DubuggerHidden” attribute which tells the Visual Studio debugger that the method is hidden from the debugging process and while debugging. In this blog post I am going to explain one similar features of “DebuggerHidden” attributes, named “DebuggerStepThrough” 

Marking a piece of code using DebuggerStepThrough attribute tells the Visual Studio debugger that, the code block will be stepped over from debugging process. you can mark methods, properties with DebuggerStepThrough attributes where you don’t want to stop your code to break.

If there is any break point inside a code section which is marked as “DebuggerStepThrough” attributes, that code block will be marked as “[External code]” in stack Trace. Where as “Debugger hidden” attributes didn’t marked is External code.

Color Indicator for Code Changes – Track Changes in Visual Studio 2010

Track Change” one of the best interesting features in visual studio which indicates the code changes with a color indicator at the beginning of the line.  Generally we know about the two color indicator  “Green” and “Yellow” which are used indicting the color change till VS 2008 along with those VS 2010 introduced another new color “Orange” which indicates some additional track change for undoing file after save. In this blog post I am going to explain how those color indicator helps developers to track the code changes.

In Visual Studio 2010, there is three color indicator

TrackChange_Green  Green color indicates the lines  which you have edited before your last save.  Save again the file and green mark will be disappear.

  TrackChange1

TrackChange_Yellow Yellow color indicates the lines which  you have edited since the  last save of that file.  Yellow becomes Green after saving of the file. Once you close the file that indication disappears.

 TrackChange2

TrackChange_Orange This color indication has newly introduced in VS 2010.  This color will come when  user does an undo after a save operation for that current file. Orange color indicates  that current changed line is different from the saved version of the file. 

 TrackChange3

Use “Obsolete” attributes to indicate Obsolete Methods

In this post I have explained how you can use Obsolete attributes to mark some methods which are not no longer in used or may be remove in future release of the class.  During the development cycle we may need to change the name or declaration  of certain methods which may be using by some other developers. In this case if you changed the name or declaration of that method, application may crash in different point of times as it’s being used by other developer in the application. In this case you can use System.ObsoleteAttributes  class to generate compiler warning and indicate the method as Obsolete.
