  • Can I suppress or enforce URLs to be prefaced with http:// in ALL browsers?

    - by Ryan Dunlap
    I want to ensure that regardless of what browser a user is in, they all see the EXACT same characters in the URL bar. Most browsers show the preceding protocol type in the URL bar. However, Chrome for example truncates http:// (not sure about https) and starts with the domain name, ie: Chrome: stackoverflow.com/questions/ask Safari: http://stackoverflow.com/questions/ask So, is there a way to either suppress the http:// in all browsers, or even enforce it in all browsers? Preferably suppress.

  • How can I check the network connection type using the Windows API?

    - by Jufkey
    How can I programmatically retrieve the current connection type (eg. LAN or Direct connection)? InternetGetConnectedState() isn't very reliable. For instance, I'm connected to a wireless network, but ConTypeRet is 18, which is INTERNET_CONNECTION_LAN & INTERNET_RAS_INSTALLED. Isn't there any way to make sure that ConTypeRet is either INTERNET_CONNECTION_LAN or INTERNET_CONNECTION_MODEM?

  • Federated (Synced) Subversion servers?

    - by Adam Haile
    Is it possible to create "federated" Subversion servers? As in one server at location A and another at location B that sync up their local versions of the repository automatically. That way when someone at either location interacts with the repository they are accessing their respective local server and therefore has faster response times.

Hope this makes some sense.

  • How do I correlate build configurations in dependant vcproj files with different names?

    - by Tim
    I have a solution file that requires a third party library (open source). The containing solution uses the typical configuration names of "Debug" and "release". The 3rd party one has debug and release configs for both DLL and static libs - their names are not "Debug" and "Release". How do I tell the solution to build the dependency first and how do I correlate which config to the dependant config? i.e. MyProject:Debug should build either 3rdParty:debug_shared or 3rdParty:debug_static

  • Working on a cross platform library...

    - by Alon
    What are the best practices on writing a cross platform library in C++? My development environment is Eclipse CDT on Linux, but my library should have the possibility to compile natively on Windows either (from Visual C++ for example).

    SELECT ..WHERE COL IN(A,B) or SELECT ... WHERE (COL = A or COL = B) I'm trying to find out what are the differences between the two constructs? Would there be significant performance gains either way if utilized on resultsets that are nearing the 1 million mark?

  • Is there a better alternative to the Mongo shell?

    - by afvasd
    Dear Everyone, Is there a better shell than the native mongo shell? When I press UP I am seeing ^[[A . Does the shell not support last query? Tabbing in the shell does not autocomplete either. Of course, if there's a shell with syntax highlighting that would be great Is there an alternative that has the following features? (Or at least has some of them).

  • How to determine which version of Oracle Client is being used from the server.

    - by Robert Love
    Using Oracle 10g. ( 10.2.0.4 ) Possibly by looking at either logs or system tables is there a way to determine which version of the oracle client each connection is using. Our systems initially had 8.1.7 Clients, and then 9.X clients. We attempted to manually locate all machines that had older clients and upgrade them to to 10.2 Clients. We are seeking a method to audit (from the server) if we were successful in upgrading all of our client machines.

  • Restoring and passing data to an already running instance of a .NET application

    - by mtranda
    The goal is to have an application that runs in the system tray and can either accept user input from its actual GUI (which isn't the actual issue) OR accept command line parameters (that would actually be done via a context menu in windows explorer). Now, while I'm aware that the command line parameters are not exactly possible once the application has started, I need a way to pass data to the already running application instance via some form of handler. I'm thinking maybe define and raise some sort of event? Thanks in advance.

  • using makefile targets to set build options

    - by leo grrr
    This is either trivial or runs counter to the philosophy of how make should be used, but I'd like to have a command line that reads as "make debug" rather than "make DEBUG=1". I tried creating a phony target called debug that did nothing except set the DEBUG variable, but then there was a difference between "make debug build" and "make build debug"--namely that in one case, the variable got set after the build happened. Is there a way to give certain targets precedence? Thanks for your help.

  • System.IO.Path or equivelent use with Unix paths

    - by pm_2
    Is it possible to either use the System.IO.Path class, or some similar object to format a unix style path, providing similar functionality to the PATH class? For example, I can do: Console.WriteLine(Path.Combine("c:\\", "windows")); Which shows: "C:\\windows" But is I try a similar thing with forward slashes (/) it just reverses them for me. Console.WriteLine(Path.Combine("/server", "mydir")); Which shows: "/server\\mydir"

  • relaunch app when it ends or when it prints out certain text (stdout)

    - by acidzombie24
    I have an app which acts almost like a daemon. Sometimes it quits on error and many times it prints an error msg then ask users to press any key to close. How can i relaunch the app when either case happens? I am more interested in the 2nd case. I can do this in c++, C# or python. The script is an old python that i dont want to change (a newer c# version is in the works but not stable)

  • Detecting operating system or computer name through a Java servlet

    - by Ankur
    I have a Java web app that I develop on a Windows machine and will deploy on a Unix machine. There are some file path settings and permissions details that differ on the two (and there is nothing I can do to change this). Is there some way of detecting which machine the app is sitting on (it's only one of two), either by detecting the operating system or the computer's name so I can then using the appropriate settings.

  • How do i provide a custom session ID getter/setter in asp.net

    - by Monsters
    I want to pass the sessionID as a json parameter, I can see how to override SessionIDManager and such, but this just covers custom creation/validation of sessionID's as opposed to where it actually gets the sessionID from. There is of course 'cookieless' which puts it in the url, but that doesn't work for me either. So i'd like to override the session handling so I can specify where it should look for the sessionID.
