  • How to compile libsox with MinGW

    - by kaykun
    Hi, I'm trying to use libsox into another program of mine, but I can't seem to compile libsox with MinGW or find any places with working binaries. I downloaded the source from the official site http://sox.sourceforge.net/ but I don't know which files to include in the project to compile it. I can't compile it with all the files included in the 'src' directory and I think I only need to compile the functions listed here: http://sox.sourceforge.net/libsox.html but I can't seem to find it. Can anyone help?

  • Getting a screenshot of a page using C# - Need help with code

    - by Ender
    I'm writing a specialised crawler and parser for internal use and I require the ability to take a screenshot of a web page in order to check what colours are being used throughout. The program will take in around ten web addresses and will save them as a bitmap image, from there I plan to use LockBits in order to create a list of the five most used colours within the image. To my knowledge it's the easiest way to get the colours used within a web page but if there is an easier way to do it please chime in with your suggestions. Anyway, I was going to use this program until I saw the price tag. I'm also fairly new to C#, having only used it for a few months. Can anyone provide me with a solution to my problem of taking a screenshot of a web page in order to extract the colour scheme? EDIT: Sorry for not getting back to this sooner, but I've been busy with some other things. Anyway, the code seems to work well, but the problem I am having right now is that I am running it within a form, and naturally with Application.Run() being called I cannot run two instances of the same form at once. It recommended Form.showDialog() but that broke everything. Can anyone give me a hand with this code? public static void buildScreenshotFromURL(string url) { int width = 800; int height = 600; using (WebBrowser browser = new WebBrowser()) { browser.Width = width; browser.Height = height; browser.ScrollBarsEnabled = true; // This will be called when the page finishes loading browser.DocumentCompleted += new System.Windows.Forms.WebBrowserDocumentCompletedEventHandler(OnDocumentCompleted); //browser.DocumentCompleted += OnDocumentCompleted; browser.Navigate(url); // This prevents the application from exiting until // Application.Exit is called // Application.Run() does not work as it cannot be called twice, recommended form.showDialog() // but still issues Application.Run(); } } public static void OnDocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { // Define size of thumbnail neded int thumbSize = 50; // Now that the page is loaded, save it to a bitmap WebBrowser browser = (WebBrowser)sender; // Code edited from example below to make smaller bitmap and save as PNG using (Graphics graphics = browser.CreateGraphics()) { using (Bitmap bitmap = new Bitmap(browser.Width, browser.Height, graphics)) { Rectangle bounds = new Rectangle(0, 0, bitmap.Width, bitmap.Height); browser.DrawToBitmap(bitmap, bounds); Bitmap thumbBitmap = new Bitmap(bitmap.GetThumbnailImage(thumbSize, thumbSize, thumbCall, IntPtr.Zero)); thumbBitmap.Save("screenshot.png", ImageFormat.Png); handleImage(thumbBitmap); } }

  • Cracking the Playfair cipher

    - by wwrob
    I have the ciphertext and an encrypting program (with the key hardcoded in). How would I go about finding the key? Surely the availability of the encryptor must open up possibilities beyond brute-forcing it.

  • How to know a device's name from its device ID in OS X?

    - by yangumi
    Hi all, I'm writing a program in OS X that receives click events from a mouse and a touchpad. When the user clicks at somewhere, the OS sends the device ID, which is just an int, and the position of the cursor to my callback function. I want to know if the click event comes from mouse or touchpad. So, how can I know the device's name from its device ID? Thank you! (I'm sorry for my poor English.)

  • C++: How to extract a string from rapidxml

    - by hamishmcn
    In my C++ program I want to parse a small piece of XML, insert some nodes, then extract the new XML (preferably as a std::string) RapidXML (http://rapidxml.sourceforge.net/) has been recommended to me, but I can't see how to retrieve the XML back as a text string. (I could iterate over the nodes and attributes and build it myself, but surely there's a build in function that I am missing) Thank you

  • How to debug MinGW32-make batch files?

    - by bryceman
    I'm having some difficulties building up some cross-platform Makefiles, and I'm getting errors from processes called by mingw32-make that don't make the problem clear. I've tried calling mingw32-make with "-d", and I get a lot of debug output, but the actual program invocations are hidden in temporary batch files that are immediately deleted. Is there any way to keep these batch files around, so that I can actually see what mingw32-make is doing under the hood, and fix what I assume is my problem?

    - by Daniel
    Hi folks, I have a tricky XSLT transformation and I'd like your advise My xml is formatted as below: <Person> <name>John</name> <date>June12</date> <workTime taskID=1>34</workTime> <workTime taskID=2>12</workTime> </Person> <Person> <name>John</name> <date>June12</date> <workTime taskID=1>21</workTime> <workTime taskID=2>11</workTime> </Person> The output xml should be: <Person> <name>John</name> <taskID>1</taskID> <workTime> <date>June12</date> <time>34</time> </worTime> <workTime> <date>June13</date> <time>21</time> </worTime> </Person> <Person> <name>John</name> <taskID>2</taskID> <workTime> <date>June12</date> <time>12</time> </worTime> <workTime> <date>June13</date> <time>11</time> </worTime> </Person> Essentially, as an input, a "Person" object gathers all the task/workTime for a specific date.
