• .NET Development What is .net Framework

  The Microsoft .NET Framework is a software component that can be added to the Microsoft Windows operating system. It provides a large body of pre-coded solutions to common program requirements, and manages the execution of programs written specifically for the framework. The .NET Framework is a key Microsoft offering, and is intended to be used by most new applications created for the Windows platform. The pre-coded solutions form the framework's class library and cover a large range of programming needs in areas including the user interface, data access, cryptography, web application development, numeric algorithms, and network communications. The functions of the class library are used by programmers who combine them with their own ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. JIT register allocation and bounds checking

  A few questions for Shawn or one of his buddies: 1/ Does the register allocator used in the XBox JITter use all of the available scalar floating point registers If not, how many can it deal with 2/ Does the XBox VM ever skip array bounds checking, and if so under what conditions 3/ Presumably there are no bounds checks when using unsafe code and pointers 4/ Are the method inlining limitations of the CF VM mentioned here still applicable to the XBox VM - especially the one about not inlining any method with floating point arguments or return values (yikes, that would be all floating point setters and getters!)

• SQL Server invalid reconciler parameter

  First of all... thanks for a great and interesting product... this is really nice... I'm working with a winform app and pushing it out via click-once deployment (using the bootstrapper for SQLCompact as well)... the SQL install is fine, however when my app attempts to do anything with the db, i get an error "invalid reconciler parameter" error... some searching seems to indicate that this could be coming from the path being longer than 128chars... howeve, using click once, i'm not certain I can control the deployment location... I'm certain that there is a work around, but not sure what it is... any guidance As a note, running the app on the same machine using the output from VS (not installed via ClickOnce but simply runni ...Show All

• SQL Server Percentage Format

  I am trying to display a figure as a Percentage. The figure is 2.00000. I want it to show as 2.00%. When i go into the formatting i select P but it displays the figure as 200.00%. What formatting code should i use to get 2.00% The format code 'P' multiplies your value by 100 then adds the % symbol at the end. You can do a couple things to get this fixed. Remove where you are multiplying the value by 100 in code, then set the format code to 'P'. Another way is to use this as your expression for your field. =Format(Fields!Field1.Value, "0.00" ) & "%" Hope this helps. Jarret ...Show All
