    - by markus
    Hi, In an if statement with multiple conditions is second executed if the outcome is clear after checking the first condition? example: if(i>0 && array[i]==0){ } If I swap the conditions a seg fault may occur for negative values of i but this way the memory debugger doesn't find a problem. Can I be sure that this works always or do have have to use nested if statements?

  • Shakin' things up

    - by j-t-s
    Hi All I have a little app here, and I would love to be able to do my own stuff in Vista/Win7 when I shake the form. Currently, when a form is shaken, it will restore/minimize everything else. But I want to change that behavior in my app only. So when my form is shaken, I could, for example, shuffle the playlist, or Clear the contents of a Canvas etc... Is this possible? Thank you

  • Is "campaign_$" a bad name for a SQL column?

    - by Summer
    PostgreSQL has allowed me to name a column "campaign_$". I like the name because it's short and to the point, and other potential names like "campaign_receipts" seem longer and less clear. BUT, I wonder if I'll eventually regret putting a $ symbol in a column name, either in PHP or in some other distant part of the architecture. Should I just stick to letters and underscores? Thanks!

  • What's the easiest way to create an extensible custom container in Flex?

    - by Chris R
    I want to create an MXML container component that has some of its own chrome -- a standard query display, et al -- and that supports the addition of child components to it. Something a lot like the existing mx:Panel class, which includes a title label, but acts like a plain mx:Box with regards to adding children. What's the easiest way to do this? Edit: To be clear, I want to be able to extend the container using MXML, so the "Multiple visual children" problem is relevant.

  • Is it possible to format C++ code with VIM?

    - by Werner
    Hi, I am rather new to VIM. I got some source code and this is a mess. At a first sight I would like at least to get a clear and organised view of the code, so I like to get it rightly formatted, I mean indented depending on the depth of the functions and so. I wonder if it can be done with VIM, and otherwise which other commandline tools for that can you recommend. Thanks
