Deepak Dhakal's Blog: Parameter Sniffing and Reporting service through Visual studio

Today I had a very bad day. My friend left me a job that he estimated for 2 hours and Now I need to finish that ..There is no chance that i can write multiple pages sql Stored procedures /query and create report in 2 hours .. It is going to take me at least 15 hours for everything .. Ok that is not the point .. the point .. I spent 5 hours to write all the query .. tested in Sql query manager and ran great ... Thought I was really good .. created a report layout .. added few dataset and ran the report using VS 2005 IDE .. Now the drama begins .. It took 5-10 mins to render report by VS 2005. I went to sql server machine.. checked for task manager .. CPU uses was more than 50% for that 10 mins time .WOW .. When I ran the same query in query manager .. it took less than 5 seconds .. I was upset .. restarted VS .. restarted computer .. nothing happened .. recompiled code .. redeployed .. Nothing ..Nothing at all.. I googled about it .. I am not only one.. If u have same problem .. Google...

CSS Inheritance An explanation of how inheritance works in CSS and why CSS doesn't need Object Oriented style inheritance. Introduction Many newcomers to CSS are confused by inheritance; this is often because they come from a background in object oriented (OOP) programming and expect CSS to work in a similar way. This document attempts to explain CSS inheritance and present alternatives to OO-style inheritance to demonstrate why it is not necessary. CSS Inheritance CSS inheritance works on a property by property basis. When applied to an element in a document, a property with the value 'inherit' will use the same value as the parent element has for that property. For example, given this style sheet: `.foo { background-color: white; color: black; } `.bar { background-color: inherit; color: inherit; font-weight: normal; } And this HTML fragment: div class="foo"> Hello, world. This is a very short paragraph! `div> The background colour of ...

1. Reverse a singly linked list // // iterative version // Node* ReverseList( Node ** List ) { Node *temp1 = *List; Node * temp2 = NULL; Node * temp3 = NULL; while ( temp1 ) { *List = temp1; //set the head to last node temp2= temp1->pNext; // save the next ptr in temp2 temp1->pNext = temp3; // change next to privous temp3 = temp1; temp1 = temp2; } return *List; } 2. Delete a node in double linked list void deleteNode(node *n) { node *np = n->prev; node *nn = n->next; np->next = n->next; nn->prev = n->prev; delete n; } 3. Sort a linked list //sorting in descending order struct node { int value; node* NEXT; } //Assume HEAD pointer denotes the first element in the //linked list // only change the values…don’t have to change the //pointers Sort( Node *Head) { node* first,second,temp; first= Head; while(first!=null) { second=first->NEXT; while(second!=null) { if(first->value value) { temp = new node(); temp->value=first->value; first-...

What is encapsulation?? Containing and hiding information about an object, such as internal data structures and code. Encapsulation isolates the internal complexity of an object's operation from the rest of the application. For example, a client component asking for net revenue from a business object need not know the data's origin. What is inheritance? Inheritance allows one class to reuse the state and behavior of another class. The derived class inherits the properties and method implementations of the base class and extends it by overriding methods and adding additional properties and methods. What is Polymorphism?? Polymorphism allows a client to treat different objects in the same way even if they were created from different classes and exhibit different behaviors. You can use implementation inheritance to achieve polymorphism in languages such as C++ and Java. Base class object's pointer can invoke methods in derived class objects. You can also achieve polymorphism i...

Area Number One: Coding The candidate has to write some code. Give them a coding problem that requires writing a short, straightforward function. They can write it in whatever language they like, as long as they don't just call a library function that does it for them. It should be a trivial problem, one that even a slow candidate can answer in 5 minutes or less. (If the candidate seems insulted by the thought of having to get their hands dirty with a trivial coding question, after all their years of experience, patents, etc., tell them it's required procedure and ask them to humor you. If they refuse, tell them we only interview people who can demonstrate coding skills over the phone, thank them for their time, and end the call.) Give them a few minutes to write and hand-simulate the code. Tell them they need to make it syntactically correct and complete. Make them read the code to you over the phone. Copy down what they read back. Put it into your writeup. If th...

 What are the benefits of OOD? o Object oriented design facilitates “Reusability”, “Extensibility” and “Modularity” of the software. We can divide the software into many components/classes so that “Abstraction” can be done on the changing part and non changing part to support the “changeability”. Plus Inheritance, Composition and polymorphism will always help in implementation.  Explain how the Garbage Collector works in C# o The GC of the C# (.Net rather) is a cool component in .NET framework. Being a C++ programmer, I truly understand the importance of it. I don’t need to worry about allocating /freeing the memory once I use it in .net. In c#, all the object memory management is done in “Managed heap. GC collects the unused memory based on metadata information which gives the memory layout of the created object. It performs the collection in two phases. Mark -> GC first finds the root of each object and traverse to the bottom of it adding each object and make a graph of it. It...

WHY ? It supports playback of WMV files on both PC and Macintosh, with many options for interactivity during playback; with just a couple of lines of code, you can provide a platform-neutral way to handle all your movie files. Silverlight supports full-screen 720p video and offers seamless transitions between full-screen and windowed mode without losing your position in the video (something that media sites are crying out for today). By separating markup (XAML) from code, Silverlight provides a familiar web metaphor for designers and developers. You can embed XAML directly within an HTML file if you want a simple, monolithic solution, or you can keep the two separate to enforce a delineation between different web development roles. Silverlight and HTML integrate seamlessly together. Every XAML element can be accessed or manipulated from the same client-side JavaScript that would be used to interact with any DHTML element: there are no artificial boundaries or barriers, and you can even...

: The Relational Model Purpose : Concepts, terminology. Express queries in relational algebra and relational calculus. Translate between relational algebra and SQL (Lesson 6). e.g. Student, Courses, Grades relations (tables) An attribute in an entity-relationship diagram has a domain , that is, a datatype and a range of valid values. For example, zip code is a five-digit positive number. A Cartesian product of domains is a set containing all possible combinations of elements, one from each domain. For example, a chessboard presents the Cartesian product of the rows (a-h) with the columns (1-8), with one square for each combination b5, h2, etc. A tuple is an element of a Cartesian product. A relation is a subset of a Cartesian product. For example, the set of valid values for (city, state, zip code) form a relation. Note that this relation contains information, whereas the Cartesian product City x State x Zip contains no information. In a relation, ...
