  • How to test if a gawk string contain a number?

    - by Tim Menzies
    In gawk I know two ways to test if a string contains a number. Which is best? Method one: using regular expressions: function method1(x) { return x ~ /^[+-]?([0-9]+[.]?[0-9]*|[.][0-9]+)([eE][+-]?[0-9]+)?$/ } Method two: the coercion trick (simpler): function method2(x) { return (x != "") && (x+0 == x) } Is there any reason to favor the more complex method1 over the simpler method2?

  • Is there a free web file manager like Plesk or cPanel in ASP.Net

    - by Ron Klein
    I'm looking for a free, open-sourced web application written in C#/VB.Net on top of ASP.Net, which functions like Plesk or cPanel when it comes to (remote) file management. Something that simulates a regular FTP client, but actually displays web pages over HTTP, with the following functions: Create Folder Rename File/Folder Delete File/Folder Change Timestamp ("Touch") Move Archive etc. I saw a few commercial tools, but nothing when it comes to OSS. Any ideas? links?

  • Comet without AJAX

    - by Carl Whalley
    Suppose I only had the regular J2SE http libraries but wanted to write a client for comet, say in Android etc, but not limited to that, i.e. not using a WebView. Since there's no browser I'm assuming you'd have to open the long term connections yourself ... is this feasible?

  • How to collect the new "Applications and Services Logs" found on Windows 7 or Windows Server 2008 us

    - by Mark
    In Windows Server 2008 and Windows 7 there are new Events categorized under "Applications and Services Logs". There is also a subfolder called Microsoft which has tons of subfolders as well. Is there any way to collect these events through WMI? For the regular "Windows Logs" such as Application and Security, it is possible to use the Win32_NTLogEvent WMI class in the cimv2 namespace. However, this class does not provide access to the new Microsoft event logs. Any ideas?

  • Need Flex Regex Validation Expression for password that allows for only alphanumeric values and requ

    - by BlueDude
    Hi I'm trying to setup a RegexpValidator that only accepts a string of alphanumeric characters between 6-30 characters long and requires one number. I'm new to Regular Expressions and everything I've tried seems to keep returning an invalid ValidationRsultEvent. Here's a chunk of code: <mx:RegExpValidator id="regexValidator" source="{passwordInput}" property="text" triggerEvent="" valid="onPasswordValidate(event)" invalid="onPasswordValidate(event)" /> private function validateRegister():void { regexValidator.expression = "^(?=.*(\d|\W)).{6,30}$"; regexValidator.validate(); }

  • Cleaning an XML file in Python before parsing

    - by Sam
    I'm using minidom to parse an xml file and it threw an error indicating that the data is not well formed. I figured out that some of the pages have characters like ไอเฟล &, causing the parser to hiccup. Is there an easy way to clean the file before I start parsing it? Right now I'm using a regular expressing to throw away anything that isn't an alpha numeric character and the </> characters, but it isn't quite working.

  • Re-naming chart legend in Access 2007

    - by rick
    In an auto-generated chart based on a query (I dragged the chart object onto a blank form to start it), the chart itself is displaying and updating properly, datawise, but I want to change the Legend from reading "SumOfAvgOfield1" and "SumOfAvgOfield2" to regular words suitable for final presentations. But I can't find a way to change it!

  • How could I make geometry advanced operations on bezier paths?

    - by yizzreel
    I have a library that draws regular bezier path figures (complex paths formed of a lot of bezier points), using midpoint approximation. I can draw them without problem, but I need to add support for advanced geometry operations: Nearest point of a curve, intersection, figure contains point, and more importantly, path combinations: difference, intersection, exclusive-or, union, ... Is there any good source to get all this? Thanks
