  • Convert Environment.OSVersion to NTDDI version format

    - by David Brown
    In sdkddkver.h of the Windows Platform SDK, there are various OS versions defined as NTDDI_*. For example, Windows XP and its service packs are defined as: #define NTDDI_WINXP 0x05010000 #define NTDDI_WINXPSP1 0x05010100 #define NTDDI_WINXPSP2 0x05010200 #define NTDDI_WINXPSP3 0x05010300 #define NTDDI_WINXPSP4 0x05010400 There are also masks which, along with the OSVER, SPVER, and SUBVER macros, allow you to pull the respective parts out of the NTDDI version. #define OSVERSION_MASK 0xFFFF0000 #define SPVERSION_MASK 0x0000FF00 #define SUBVERSION_MASK 0x000000FF I have all of these defined as constants in C# and what I'd like to do now is convert the data returned by Environment.OSVersion to a value corresponding to one of the NTDDI versions in sdkddkver.h. I could make a massive switch statement, but that's not really as future-proof as I'd like it to be. I would need to update the conversion method every time a new OS or service pack is released. I have a feeling this could be done with the help of some bitwise operators, but I'll be honest and say that those aren't my strong point. I appreciate any help!

  • How to format float to 2 decimals in objective C

    - by iamdadude
    I have a string that I'm converting to a float that I want to check for values in an if statement. The original float value is the iPhone's trueHeading that is returned from the didUpdateHeading method. When I convert the original float to a string using @"%.2f" it works perfectly, but what I'm trying to do is convert the original float number to the same value. IF I just convert the string to [string floatValue] I get the same original float number, and I don't want that. To make it short and simple, how do I take an existing float value and just get the first 2 decimals?

  • Problem with Json Date format when calling cross-domain proxy

    - by Christo Fur
    I am using a proxy service to allow my client side javascript to talk to a service on another domain The proxy is a simple ashx file with simply gets the request and forwards it onto the service on the other domain : using (var sr = new System.IO.StreamReader(context.Request.InputStream)) { requestData = sr.ReadToEnd(); } string data = HttpUtility.UrlDecode(requestData); using (var client = new WebClient()) { client.BaseAddress = serviceUrl; client.Headers.Add("Content-Type", "application/json"); response = client.UploadString(new Uri(webserviceUrl), data); } The client javascript calling this proxy looks like this function TestMethod() { $.ajax({ type: "POST", url: "/custommodules/configuratorproxyservice.ashx?m=TestMethod", contentType: "application/json; charset=utf-8", data: JSON.parse('{"testObj":{"Name":"jo","Ref":"jones","LastModified":"\/Date(-62135596800000+0000)\/"}}'), dataType: "json", success: AjaxSucceeded, error: AjaxFailed }); function AjaxSucceeded(result) { alert(result); } function AjaxFailed(result) { alert(result.status + ' - ' + result.statusText); } } This works fine until I have to pass a date. At which point I get a Bad Request error when the proxy tries to call the service I did have this working at one point but have now lost it. Have tried using JSON.Parse on the object before sending. and JSON.Stringify, but no joy anyone got any ideas what I am missing

  • C#: File-size format provider

    - by Seb Nilsson
    Is there any easy way to create a class that uses IFormatProvider that writes out a user-friendly file-size? public static string GetFileSizeString(string filePath) { FileInfo info = new FileInfo(@"c:\windows\notepad.exe"); long size = info.Length; string sizeString = size.ToString(FileSizeFormatProvider); // This is where the class does its magic... } It should result in strings formatted something like "2,5 MB", "3,9 GB", "670 bytes" and so on.

  • ipad vide format

    - by Mike
    When you use iTunes to sync your videos with the iPhone the videos are always saved with no more than 640 pixels wide, if I am not wrong. What about the iPad? What is the size of videos iTunes syncs with iPad? 1024x768? and what if the video has a dimension below 1024x768? Will it scale up? or will it keep the video at low res and scale when you play? thanks.

  • Excel parsing (xls) date error

    - by tau-neutrino
    I'm working on a project where I have to parse excel files for a client to extract data. An odd thing is popping up here: when I parse a date in the format of 5/9 (may 9th) in the excel sheet, I get 39577 in my program. I'm not sure if the year is encoded here (it is 2008 for these sheets). Are these dates the number of days since some sort of epoch? Does anyone know how to convert these numbers to something meaningful? I'm not looking for a solution that would convert these properly at time of parsing from the excel file (we already have thousands of extracted files that required a human to select relevant information - re-doing the extraction is not an option).

  • Audio Conversion C#

    - by Will
    What is the best way to convert various audio formats to PCM? For example: mp3, evrc, ogg vox. Is there a library out there that will allow me to implement this relatively easily? EDIT: I guess my initial question wasn't really what I needed. Most of the libs I have found are file converters. What I need is a block converter, where I pass in a 1Kb block of vox data and it returns its converted PCM block. Of course I’ll have to tell the converter what type of data it is and various pieces of codec information. The solution I am going for is to save and VOIP formats into a common wav format and to play that conformed file in real time. I thought there should be an easy way to do this because all audio is eventually turned into PCM before it is outputted anyways.

    - by erik
    I'm working w/ a function that expects a string formatted as a utf-8 encoded octet string. Can someone give me an example of what a utf-8 encoded octet string would look like? Put another way, if I convert 'foo' to bytes, I get 112, 111, 111. What would these char codes look like as a utf-8 encoded octet string? Would it be "0x70 0x6f 0x6f"? Thanks

  • Jalopy comments indentation

    - by Neil Wightman
    Hi All. We use jalopy to format our code to the sun standard (well 99%). I have 1 issue with it. It keeps moving comments to the right of the line. E.g // Panel "JPanel.border", new LazyValue(packageName + "PanelBorder"), //frozen // Button "Button.background", new ColorUIResource(251, 251, 251), //frozen "Button.foreground", new ColorUIResource(0, 0, 0), //frozen But jalopy always moves the // Button to the far right. // Panel "JPanel.border", new LazyValue(packageName + "PanelBorder"), //frozen // Button "Button.background", new ColorUIResource(251, 251, 251), //frozen "Button.foreground", new ColorUIResource(0, 0, 0), //frozen Is there any way to stop this? Thanks Neil
