• Update just one field from backup

  - by justSteve

  I'm looking to restore one field from a backup and can't find the syntax for an update statement that can look at 2 different catalogs. Seems like it should be something fairly close to: update users set idUserCompany = (select idUserCompany from .myBackup.dbo.users uT) where uT.idUser = idUser

• Why cast null before checking if object is equal to null?

  - by jacerhea

  I was looking through the "Domain Oriented N-Layered .NET 4.0 Sample App" project and ran across some code that I do not understand. In this project they often use syntax like the following to check arguments for null: public GenericRepository(IQueryableContext context,ITraceManager traceManager) { if (context == (IQueryableContext)null) throw new ArgumentNullException("context", Resources.Messages.exception_ContainerCannotBeNull); Why would you cast null to the type of the object you are checking for null?

• Are there any FREE Xaml Diff/Merge tools available?

  - by Ahikam

  I am searching a free diff tool with support of native syntax and markup for XAML, but failed to find one. I like Altova's DiffDog but it's paid. CodeCompare is an useful tool. It has some worth with its integration into VisualStudio and usage of native editors. It's a perfect solution for XML! However, it does not support XAML editors. Who can recommend a diff tool for XAML?

• What does this mean?

  - by LeonixSolutions

  I found this in some code examples while googling : $sql = 'INSERT INTO users (username,passwordHash) VALUES (?,?)'; it's new to me, but I would guess that it a substitution method and equivalent to $sql = "INSERT INTO users (username,passwordHash) VALUES ($username,$passwordHash)";` or $sql = 'INSERT INTO users (username,passwordHash) VALUES (' . $username . ',' . $passwordHash . ')';` would that be correct? Is it an actual PHP syntax, or was he just trying to simplify his example?

• Best JSF framework/library for "conversation state"

  - by stacked

  What do people think is the best JSF framework or library for a saving state longer than request scope (but w/o using session scope) that is backbutton/new window safe -- i.e. you have a "wizard"/multi-page form. For example, MyFaces has the 'SaveState' tag (http://bit.ly/8QHmX5) that allows you to maintain state across pages by saving state in the view's component tree. Any comments on SaveState (pros/cons) or suggestions for any better framework or library for this capability?

• How do you store a result to a variable and check the result in a conditional?

  - by Oesor

  I know it's possible but I'm drawing a blank on the syntax. How do you do something similar to the following as a conditional. 5.8, so no switch option: while ( calculate_result() != 1 ) { my $result = calculate_result(); print "Result is $result\n"; } And just something similar to: while ( my $result = calculate_result() != 1 ) { print "Result is $result\n"; }

  Is size_t only in C++ standard or C standard as well? I cannot find a C header in the "/usr/include" tree that defines size_t. If it is not in the C std, is GCC just doing some magic to make things work? Thanks, Chenz

• MS SQL Server stored procedure meaning

  - by den-javamaniac

  Hi. I'm developing a simple database architecture in VisualParadigm and lately ran over next code excerpt. IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'getType') AND type in (N'P', N'PC')) DROP PROCEDURE getType; Next goes my stored procedure: CREATE PROCEDURE getType @typeId int AS SELECT * FROM type t WHERE t.type_id = @typeId; Can anyone explain what does it mean? P.S.: It would be great, if you may also check for any syntax errors as I'm totally new to MSSQL and stored procedures.

• Semantic #region usage

  - by Luca

  What's your opinion about using #region folding using application semantic, instead of folding for "syntax". For example: #region Application Loop #region User Management #region This Kinf of stuffs instead of #region Private Routines #region Public Properties #region ThisRoutine // (Yes, I've seen this also!) In this logic, I'm starting fold even routine bodies. I'm starting to love #region directive (even using #pragma region when using C++!).

• What folders are commonly used by version control systems?

  - by a_m0d

  I need to know what folder names are commonly used by Version Control systems. Many VCSs will create a hidden folder, usually in the top level of the source tree, to store the information that they use. So far, I only know that Git uses .git/ and SVN uses .svn/. What are the folder names that other popular VCSs use?

• Loop over array and set all vars to false or true in javascript

  - by Sixfoot Studio

  Hi All, I need to loop over my array and set all the vars to false or true. I have tried numerous options, none of which are working and it's clearly my lack of javascript syntax knowledge..Please take a look at this: var closeAllCells = [IncomeOpen = "false", RehabOpen = "false", AttendantCareOpen = "false", HomeMaintenanceOpen = "false", DependantCareOpen = "false", IndexationOpen = "false", DeathFuneralOpen = "false", ComprehensiveOpen = "false", CollisionOpen = "false", LiabilityOpen = "false", DCPDOpen = "false"]; So my thinking is that I can just loop over this as follows for (var i=0;i<closeAllCells.length;i++) { closeAllCells[i] = true; // or false if I wished }

• How do I get Aptana to recognize .jspf files?

  - by Keith Bentrup

  How do I get Aptana to recognize .jspf files? I'd like to have syntax highlighting for .jspf files. I'm sure there's a preference/config option or an xml file to edit, but I'm not finding it. I assume it's similar to the eclipse process, so I'm tagging eclipse, too. If it's not, I'll remove the tag.
