  • Mercurial auto update problem.

    - by Ezequiel
    We are starting to use Mercurial for source control. We have configured the HGRC configuration file to do an auto update after we push to the "central" repository. With some PCs we get this error msg: warning: changegroup hook exited with status -1 HGRC looks like this: [ui] username=ADMIN verbose=true [hooks] changegroup = hg update >&2 Later we perform the update manually and everything works right.

  • How to communicate between service controller and a service/daemon?

    - by Sorin Sbarnea
    It is easy to display the status of a Windows service or to control it (start/stop) from a GUI application but the question if how about receiving/sending notifications from the service? Like: service telling to the user monitoring it that it needs attention. Please consider that you can have several controllers started at any time in a multi-user environment. Do you know an example(open source) for this kind of communication? Extra points for a platform independent solution :)

  • What is the correct verb for what programmers do?

    - by bennybdbc
    Sorry if this is a little off-topic, but I never know what word to use when I am searching the internet for articles or tutorials. What I mean is, say I wanted to search for information regarding making a notepad clone, would I search for: "Creating A Notepad Clone" "Building A Notepad Clone" "Making A Notepad Clone" So what I'm asking is basically, is there a definitive term to use, or does it vary depending on the source?

  • Why are joins bad when considering scalability?

    - by acidzombie24
    Why are joins bad or 'slow'. I know i heard this more then once. I found this quote The problem is joins are relatively slow, especially over very large data sets, and if they are slow your website is slow. It takes a long time to get all those separate bits of information off disk and put them all together again. source I always thought they were fast especially when looking up a PK. Why are they 'slow'?

  • What things must I know about OpenAL memory management?

    - by mystify
    I am playing sound with OpenAL, and it seems to increase memory footprint dramatically for every little sound I play. It seems that OpenAL never frees memory itself and that playing a Source causes memory footprint to grow. I couldn't find any good resources about OpenAL memory management, but I bet I must do a lot of stuff myself. Maybe someone knows a ressource for that?

  • Visual Studio Freezing/TFS Window Might be off screen

    - by spilliton
    I am using Visual Studio 2005 with Team Foundation Server. When I right click a file under the source control and choose "compare" VS appears to freeze until I hit escape. My guess is that the window that is supposed to be popping up is somewhere I can't get to. I tried minimizing all the windows that I can and it is nowhere to be found.

  • How to disable dragging from a Rich Edit Control

    - by John
    I use a subclass of CRichEditCtrl to provide a CEdit+ type control. One thing I want is to disable drag-drop functionality, which the base class provided by default. Disabling dropping is easy: ::RevokeDragDrop(m_hWnd); But I can't see a simple way to disable the control being a drag-source. Is there an easy way?

  • how to deal with political differences that lead to dysfunctional development environment

    - by Pierreten
    We have a few liberal programmers on our team who don't use source control, don't manage time effectively and always want to use our budget on useless tools/components that are expensive and things we can build ourselves. They are also loud and disrespectful. Our group of conservatives always have to clean up after them and show them the correct way of doing things. How do we address this discrepancy? Please advise.
