    - by m00st
    What is this syntax for in C++? Can someone point me to the technical term so I can see if I find anything in my text? At first I thought it was a prototype but then the = and (*fn) threw me off... Here is my example: void (*fn) (int&,int&) = x;

  • Reading HTTP headers from JAX-WS Web Service

    - by Anonimo
    Hi all, I currently have a JAX-WS Web Service that receives some credentials in the HTTP header. These are used for BASIC authentication. There is a filter that performs authentication by reading the HTTP headers and checking against the database. Still, I need the username from within the Web Service in order to perform other service logic related stuff. Is there a way of accessing the HTTP headers from within the Web Service? Thanks.

  • 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

  • populate a list dynamically in ant build script

    - by user1164061
    I have the following directory structure: vardir1 vardir2 vardir3 vardir4 constantdir1 Inside constantdir1, i have an ant build script which takes the list of vardir1 to vardir4 and compiles them sequentially. The situation is, vardir1 to vardir4 may or may not exist all the time. Right now I have hard coded the values in the list and checking to see if the vardir is available before I kick off its compilation. Is there any way I can dynamically populate this list in my ant build script?

  • Showing solution path in VS2008 window name

    - by Garry Shutler
    Is there a way to display the path of the solution in the Visual Studio window's name? By default it displays (SolutionName) - Microsoft Visual Studio, I would like it to instead show something like (SolutionName) - (PathToSolution) - Microsoft Visual Studio. The reason behind this is I can have multiple versions of a project checked out at a time (staging and trunk for example) and I'd like a quick way of checking without going through prompts etc.

  • it takes 2 seconds to compile a hello world C++ project in netbeans (windows)

    - by Ethan
    I used code:blocks as the C++ IDE on Windows. I switched to netbeans 6.8 (with C/C++ plugin, MinGW, MSYS) recently, because netbeas have the nice feature of "checking syntax errors when typing" (same as working on Java or PHP projects). But the painful thing is that, it takes 2 seconds to compile a simple hello world project in netbeans. Any trick to make it as fast as code:blocks, or at least make the compiling time no more than 0.5 second?

  • 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?

  • jquery - if else if?

    - by YesThatsRight
    I've been trying to figure out the syntax for an if / else if statement in jquery, but googling gives me mixed messages... There are some sites that say I need a plugin, and others that suggest that it's already possible. Trying those suggestions give me jquery errors in the jquery.js file, so I'm wondering, do I need a plugin or not? Does someone have an example of an if () { //do something } else if () { //do something else } else { //do something } in jquery?

  • Sparse checkouts and svn:externals

    - by JesperE
    I'm trying to do a sparse checkout of a folder containing externals, but none of the externals are being checked out. This issue seems to indicate that this behavior may be by design, or at least that it isn't clear what the behavior should be. From my point of view, the obvious behavior is that externals are treated just as any other directory, and checked out following the same sparse checkout rules. Is there a way to work around this except manually checking out the externals?

    Hi, I am trying to test a functionality, which inserts few details into the DB. In the test.log, it shows the insert command that is generated and also the log messages that I have placed to show the progress and everything seems to be working fine except the actual data is not getting inserted into the DB.
