  • How can I export an array from Dynamics AX 2009 via c#?

    - by Steve Homer
    I'm pulling data from Dynamics AX 2009 from c# using the following code snippet. This works fine, except for those cases where the underlying field type is a dimension. I want to be able to "flatten" array types when I return them but can't see any way to do this. Any ideas anyone? axRecord = ax.CreateAxaptaRecord(tableName); axRecord.ExecuteStmt(strQuery); // Loop through the set of retrieved records. using (StreamWriter sw = File.CreateText(path)) { AxaptaObject axDictTable = ax.CreateAxaptaObject("SysDictTable",axRecord.get_Field("tableid")); outputRow = null; List<int> ids = new List<int>(); for (int i = 1; i <= (int)axDictTable.Call("fieldCnt"); i++) { AxaptaObject axDictField = ax.CreateAxaptaObject("DictField", axRecord.get_Field("tableid"), axDictTable.Call("fieldCnt2ID", i)); outputRow += ((string)axDictField.Call("Name")) + ","; ids.Add((int)axDictTable.Call("fieldCnt2ID", i)); } sw.WriteLine(outputRow); while (axRecord.Found) { outputRow = null; foreach(int i in ids) outputRow += axRecord.get_Field(i).ToString().Replace(",", "") + ","; sw.WriteLine(outputRow); axRecord.Next(); } }

  • rails semi-complex STI with ancestry data model planning the routes and controllers

    - by ere
    I'm trying to figure out the best way to manage my controller(s) and models for a particular use case. I'm building a review system where a User may build a review of several distinct types with a Polymorphic Reviewable. Country (has_many reviews & cities) Subdivision/State (optional, sometimes it doesnt exist, also reviewable, has_many cities) City (has places & review) Burrow (optional, also reviewable ex: Brooklyn) Neighborhood (optional & reviewable, ex: williamsburg) Place (belongs to city) I'm also wondering about adding more complexity. I also want to include subdivisions occasionally... ie for the US, I might add Texas or for Germany, Baveria and have it be reviewable as well but not every country has regions and even those that do might never be reviewed. So it's not at all strict. I would like it to as simple and flexible as possible. It'd kinda be nice if the user could just land on one form and select either a city or a country, and then drill down using data from say Foursquare to find a particular place in a city and make a review. I'm really not sure which route I should take? For example, what happens if I have a Country, and a City... and then I decide to add a Burrow? Could I give places tags (ie Williamsburg, Brooklyn) belong_to NY City and the tags belong to NY? Tags are more flexible and optionally explain what areas they might be in, the tags belong to a city, but also have places and be reviewable? So I'm looking for suggestions for anyone who's done something related. Using Rails 3.2, and mongoid.

  • Powershell 2.0 Hang When Run From MsDeploy pre- post- ops using c/

    - by SonOfNun
    I am trying to invoke powershell during the preSync call in a MSDeploy command, but powershell does not exit the process after it has been called. The command (from command line): "tools/MSDeploy/msdeploy.exe" -verb:sync -preSync:runCommand="powershell.exe -NoLogo -NoProfile -NonInteractive -ExecutionPolicy Unrestricted -Command C:/MyInstallPath/deploy.ps1 Set-WebAppOffline Uninstall-Service ",waitInterval=60000 -usechecksum -source:dirPath="build/for-deployment" -dest:wmsvc=BLUEPRINT-X86,username=deployer,password=deployer,dirPath=C:/MyInstallPath I used a hack here (http://therightstuff.de/2010/02/06/How-We-Practice-Continuous-Integration-And-Deployment-With-MSDeploy.aspx) that gets the powershell process and kills it but that didn't work. I also tried taskkill and the sysinternals equivalent, but nothing will kill the process so that MSDeploy errors out. The command is executed, but then just sits there. Any ideas what might be causing powershell to hang like this? I have found a few other similar issues around the web but no answers. Environment is Win 2K3, using Powershell 2.0. UPDATE: Here is a .vbs script I use to invoke my powershell command now. Invoke using 'cscript.exe path/to/script.vbs': Option Explicit Dim oShell, appCmd,oShellExec Set oShell = CreateObject("WScript.Shell") appCmd = "powershell.exe -NoLogo -NoProfile -NonInteractive -ExecutionPolicy Unrestricted -Command ""&{ . c:/development/materialstesting/deploy/web/deploy.ps1; Set-WebAppOffline }"" " Set oShellExec = oShell.Exec(appCmd) oShellExec.StdIn.Close()

  • curl: downloading from dynamic url

    - by adam n
    I'm trying to download an html file with curl in bash. Like this site: http://www.registrar.ucla.edu/schedule/detselect.aspx?termsel=10S&subareasel=PHYSICS&idxcrs=0001B+++ When I download it manually, it works fine. However, when i try and run my script through crontab, the output html file is very small and just says "Object moved to here." with a broken link. Does this have something to do with the sparse environment the crontab commands run it? I found this question: http://stackoverflow.com/questions/1279340/php-ssl-curl-object-moved-error but i'm using bash, not php. What are the equivalent command line options or variables to set to fix this problem in bash? (I want to do this with curl, not wget) Edit: well, sometimes downloading the file manually (via interactive shell) works, but sometimes it doesn't (I still get the "Object moved here" message). So it may not be a a specifically be a problem with cron's environment, but with curl itself. the cron entry: * * * * * ~/.class/test.sh >> ~/.class/test_out 2>&1 test.sh: #! /bin/bash PATH=/usr/local/bin:/usr/bin:/bin:/sbin cd ~/.class course="physics 1b" url="http://www.registrar.ucla.edu/schedule/detselect.aspx?termsel=10S<URL>subareasel=PHYSICS<URL>idxcrs=0001B+++" curl "$url" -sLo "$course".html --max-redirs 5 As I was searching around on google, someone suggested that the problem might happen because there are parameters in the url. (Because it is a dynamic url?)

  • Cocoa/AppleScript move file

    - by bogdan
    I have a list of file paths and a destination path. I need something (AppleScript, Cocoa) that will move the files from one location to an other. I first tried using the following AppleScript, just to see what happens: set the_folder to (choose folder) tell application "Finder" move selection to the_folder end tell The problem is that it just blindly tries to move a file, nothing like the way Finder actually moves files (i.e. if a file with that name already exists, the AppleScript just throws an error, while Finder would ask you if you want to replace the file). The solution I came up with involved NSFileManager. I won't post the code because it's quite long, but basically I just check if the file already exists before trying to move, and if it exists a NSAlert with Replace/Cancel buttons appear. I have 2 remaining problems: Authorization - if you try to do something to files where you don't have access, the Finder would ask you to authorize. My code just fails... Moving to external drives - when you try to move a file to a different drive, NSFileManager copies the file and then deletes the original. The problem is that NSFileManager doesn't provide anything which I could use to display a progress indicator of what's happening during the copy. Is there anything I could use that is able to move files without these problems? The way I see it, I'm pretty much stuck with checking if the files are writable by the current user and authorize NSFileManager if not (from my understanding of the Authorization Services, this will be quite hard to implement). Oh and, I would also need to check if the destination is on the same drive and if not, implement something with FSCopyObjectAsync so that it shows a progress indicator... Thanks!

  • Prolog check if

    - by NickLee
    I'm creating a text adventure game on SWI-Prolog and I want to include (some kind of) dialogs. What I have so far is: dialog1(1):- nl,write('blah blah'),nl write('a: this is answer a'),nl, write('b: this is answer b'),nl. a:- write('respond to answer a'),nl. b:- write('respond to answer b'),nl. That's pretty much the first dialog. Now I want to create a second dialog similar to the first one. dialog1(2):- nl,write('blah blah'),nl, write('a: this is answer a'),nl, write('b: this is answer b'),nl. a:- write('respond to answer a'),nl. b:- write('respond to answer b'),nl. How can I check if the dialog is the first or the second one? I want to do that because when the user types a., I need the right answer a to be shown. I thought I could use something like a(1):- write('respond to answer a'),nl. b(1):- write('respond to answer b'),nl. /* and on the second dialog*/ a(2):- write('respond to answer a'),nl. b(2):- write('respond to answer b'),nl. But still, if the user is on dialog 2 and he types a(1),the first answer will appear.

  • Ninject problem binding to constant value in MVC3 with a RavenDB session

    - by Jim
    I've seen a lot of different ways of configuring Ninject with ASP.NET MVC, but the implementation seems to change slightly with each release of the MVC framework. I'm trying to inject a RavenDB session into my repository. Here is what I have that's almost working. public class MvcApplication : NinjectHttpApplication { ... protected override void OnApplicationStarted() { base.OnApplicationStarted(); AreaRegistration.RegisterAllAreas(); RegisterGlobalFilters(GlobalFilters.Filters); RegisterRoutes(RouteTable.Routes); } protected override IKernel CreateKernel() { return new StandardKernel(new MyNinjectModule()); } public static IDocumentSession CurrentSession { get { return (IDocumentSession)HttpContext.Current.Items[RavenSessionKey]; } } ... } public class MyNinjectModule : NinjectModule { public override void Load() { Bind<IUserRepository>().To<UserRepository>(); Bind<IDocumentSession>().ToConstant(MvcApplication.CurrentSession); } } When it tries to resolve IDocumentSession, I get the following error. Error activating IDocumentSession using binding from IDocumentSession to constant value Provider returned null. Activation path: 3) Injection of dependency IDocumentSession into parameter documentSession of constructor of type UserRepository Any ideas on how to make the IDocumentSession resolve?

  • Using layout view in Express with Consolidate and Mustache

    - by Raphael Caixeta
    I just started going through Node using Express and finally got Consolidate JS working properly to use Mustache as the templating view system per the instructions on the Consolidate JS Github page. Mustache is loading properly, but I'm now wondering how to include the layout file along in the rendering of the template. The default Jade system loads the content of the .render method inside of the layout.jade file. I'm just wondering how to do the same, but with Mustache. Any help is greatly appreciated! Code: index.js exports.index = function(req, res){ res.render('index', { title: "Work pl0x?" }); }); index.mustache Welcome to {{title}} I just want the index.mustache content to come in the "{{content}}" portion of the code below (layout.mustache). How can I do this? <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta charset="UTF-8" /> <title>Project Name | {{title}}</title> <link href="/stylesheets/style.css" rel="stylesheet" /> </head> <body> {{content}} </body> </html>

  • sizeof abuse : get the size of a const table

    - by shodanex
    When declaring a const table, it is possible to get the size of the table using sizeof. However, once you stop using the symbol name, it does not work anymore. is there a way to have the following program output the correct size for table A, instead of 0 ? #include <stdio.h> struct mystruct { int a; short b; }; const struct mystruct tableA[] ={ { .a = 1, .b = 2, }, { .a = 2, .b = 2, }, { .a = 3, .b = 2, }, }; const struct mystruct tableB[] ={ { .a = 1, .b = 2, }, { .a = 2, .b = 2, }, }; int main(int argc, char * argv[]) { int tbl_sz; const struct mystruct * table; table = tableA; tbl_sz = sizeof(table)/sizeof(struct mystruct); printf("size of table A : %d\n", tbl_sz); table = tableB; tbl_sz = sizeof(tableB)/sizeof(struct mystruct); printf("size of table B : %d\n", tbl_sz); return 0; } Output is : size of table A : 0 size of table B : 2

  • .NET 4.0 Forms Authentication change?

    - by James Koch
    I'm seeing some new behavior in Forms Authentication after upgrading to .NET 4.0. This occurs only on IIS 6, not on 7. Background - In web.config, we configure Forms Authentication, and then use <authorization tags to globally deny anonymous/unauthenticated users access. Then we explicitly allow access to a login.aspx page using a <location tag. Generally, this works fine, as it did when we were on .NET 2.0 (3.5). The issue only occurs when we visit the root path of the site, ie "http://myserver/". Our default document is configured in IIS to be login.aspx. Under .NET 4.0, upon visiting that URL, we're redirected to "http://myserver/login.aspx?ReturnUrl=/". If you log in from here, you're logged in and returned back at the log in page (yuck). Just wanted to post this here to see if anyone else is experiencing this. It's not listed on any "breaking changes" documentation I've been able to find. Either I'm missing something, or the UrlAuthorization module has changed and is no longer "smart" about IIS default documents.

  • Changing save directory

    - by Nathan
    Disregard my previous pre-edit post. Rethought what I needed to do. This is what I'm currently doing: https://developer.mozilla.org/en/XPCOM_Interface_Reference/nsIScriptableIO downloadFile: function(httpLoc) { try { //new obj_URI object var obj_URI = Cc["@mozilla.org/network/io-service;1"].getService(Ci.nsIIOService). newURI(httpLoc, null, null); //new file object //set file with path obj_TargetFile.initWithPath("C:\\javascript\\cache\\test.pdf"); //if file doesn't exist, create if(!obj_TargetFile.exists()) { obj_TargetFile.create(0x00,0644); } //new persitence object var obj_Persist = Cc["@mozilla.org/embedding/browser/nsWebBrowserPersist;1"]. createInstance(Ci.nsIWebBrowserPersist); // with persist flags if desired const nsIWBP = Ci.nsIWebBrowserPersist; const flags = nsIWBP.PERSIST_FLAGS_REPLACE_EXISTING_FILES; obj_Persist.persistFlags = flags | nsIWBP.PERSIST_FLAGS_FROM_CACHE; //save file to target obj_Persist.saveURI(obj_URI,null,null,null,null,obj_TargetFile); return true; } catch (e) { alert(e); } },//end downloadFile As you can see the directory is hardcoded in there, I want to save the pdf file open in the active tab to a relative temporary directory, or anywhere that's out of the way enough that the user won't stumble along and delete it. I'm going to try that using File I/O, I was under the impression that what I was looking for was in scriptable file I/O and thus disabled.

  • How to convert struct to char array in C

    - by falcojr
    I'm trying to convert a struct to a char array to send over the network. However, I get some weird output from the char array when I do. #include <stdio.h> struct x { int x; } __attribute__((packed)); int main() { struct x a; a.x=127; char *b = (char *)&a; int i; for (i=0; i<4; i++) printf("%02x ", b[i]); printf("\n"); for (i=0; i<4; i++) printf("%d ", b[i]); printf("\n"); return 0; } Here is the output for various values of a.x (on an X86 using gcc): 127: 7f 00 00 00 127 0 0 0 128: ffffff80 00 00 00 -128 0 0 0 255: ffffffff 00 00 00 -1 0 0 0 256: 00 01 00 00 0 1 0 0 I understand the values for 127 and 256, but why do the numbers change when going to 128? Why wouldn't it just be: 80 00 00 00 128 0 0 0 Am I forgetting to do something in the conversion process or am I forgetting something about integer representation? *Note: This is just a small test program. In a real program I have more in the struct, better variable names, and I convert to little-endian. *Edit: formatting

  • 1. I fill out a form & click submit. 2. I get the results page. Goal: Get the same results without f

    - by Chris
    This is my first time posting - I greatly appreciate any and all guidance on this subject. Background: I am building a Real Estate web site. I would like to use the free IDX data provided by my local MLS board. The MLS board does not allow me the option of displaying a predefined search and only provides me with a link to the search field. after filling out the search field, I am able to view the results. Goal: I would like to bypass this step and frame the results page into a GoDaddy website I am building, which supports HTML. Here is a link to the search page: http://fgcmls.rapmls.com/scripts/mgrqispi.dll?APPNAME=Fortmyers&PRGNAME=MLSLogin&ARGUMENT=vBSJvLQtMcbg7F0O0KnXDiggv%2F12B0S6Ss9wv4510QA%3D&KeyRid=1 I am trying to only show the listings that appear in my neighborhood. Options include: 1. Property Type - Residential 2. GEO Area - FM11 3. Developments: Fiddlesticks Country Club Once this criteria is entered, I have the page needed to make this project work. Thank all of you for taking the time to read this and for the time you spend helping me out. Best regards, Chris

  • Using the Microsoft Ajax Minifier with Web Setup project & Source Control

    - by Rob
    I've just started investigating the Microsoft Ajax Minifer 4.0 for use with a Visual Studio 2008 Web Application I work on. It's proven easy enough to hook it into the .csproj file so it produced .min.js files for all scripts, however I'm stumped as to how to integrate this with the Web Setup project & Source Control. Essentially what I want to do is have the resultant .min.js files included in the Web Setup project without having them included in Source Control because: Having to check them out prior to the build being executing is a pain (the minifier cannot modify them if they're not checked out). As they're created as a "build artifact" it just seems wrong to have them stored under source control. The only option I've managed to come across so far is to explicitly include the .min.js files as part of the Setup project by right clicking on the Web Setup project and choosing "Add File", and then having the relevant folder hierarchy duplicated in "File System on Target Machine" so that I can force the file to the correct location. This is neither elegant or simple/robust as: It requires me to manually add every minified js file to the Web Setup project by hand Maintain a copy of the relevant directory structure in both the Web Application project and the Web Setup project Remember to add any new js files minified versions to the Web Setup project Is there a better way of doing this?

  • Routing trouble for RESTful API - Rails

    - by aressidi
    I'm building out an API for web app that I've been working on for some time. I've started with the User model. The user portion of the API will allow remote clients to a) retrieve user data, b) update user information and c) create new users. I've gotten all of this to work, but it doesn't seem like its setup correctly. Here are my questions: Should the API endpoint be users or user? What's the best practice? I have to add the action to the end, which I would expect to be picked up instead by the request type so I don't have to specify it explicitly. How do I get my routes setup properly as not to have to include the method for protected actions? Let me give some examples: Get request for show - want it to work without the "show" curl -u rmbruno:blah http://app.local/api/users/show Put request for update - want it to work without the "update" curl -X put -F 'user[forum_notifications]=true' -u rmbruno:blah http://app.local/api/users/update Create - works with or without 'create' which is what I want for all these actions curl -X post -F 'user[login]=mamafatta' -F 'user[email][email protected]' -F 'user[password]=12345678' http://twye.local/api/users/ How do I structure routes to not require the action name? Isn't that the common way to to RESTful APIs? Here is my route for the API now: map.namespace :api do |route| route.resources :users route.resources :weight end I'm using restful authentication which is handling the http auth in curl. Any guidance on the routes issues and best practice on singular versus plural would be really helpful. Thanks! -A

  • tipfy for Google App Engine: Is it stable? Can auth/session components of tipfy be used with webapp?

    - by cv12
    I am building a web application on Google App Engine that requires users to register with the application and subsequently authenticate with it and maintain sessions. I don't want to force users to have Google accounts. Also, the target audience for the application is the average non-geek, so I'm not very keen on using OpenID or OAuth. I need something simple like: User registers with an e-mail and password, and then can log back in with those credentials. I understand that this approach does not provide the security benefits of Google or OpenID authentication, but I am prepared to trade foolproof security for end-user convenience and hassle-free experience. I explored Django, but decided that consecutive deprecations from appengine-helper to app-engine-patch to django-nonrel may signal that path may be a bit risky in the long-term. I'd like to use a code base that is likely to be maintained consistently. I also explored standalone session/auth packages like gaeutilities and suas. GAEUtilities looked a bit immature (e.g., the code wasn't pythonic in places, in my opinion) and SUAS did not give me a lot of comfort with the cookie-only sessions. I could be wrong with my assessment of these two, so I would appreciate input on those (or others that may serve my objective). Finally, I recently came across tipfy. It appears to be based on Werkzeug and Alex Martelli spoke highly of it here on stackoverflow. I have two primary questions related to tipfy: As a framework, is it as mature as webapp? Is it stable and likely to be maintained for some time? Since my primary interest is the auth/session components, can those components of the tipfy framework be used with webapp, independent of the broader tipfy framework? If yes, I would appreciate a few pointers to how I could go about doing that.

  • How to load JPG file into NSBitmapImageRep?

    - by Adam
    Objective-C / Cocoa: I need to load the image from a JPG file into a two dimensional array so that I can access each pixel. I am trying (unsuccessfully) to load the image into a NSBitmapImageRep. I have tried several variations on the following two lines of code: NSString *filePath = [NSString stringWithFormat: @"%@%@",@"/Users/adam/Documents/phoneimages/", [outLabel stringValue]]; //this coming from a window control NSImageRep *controlBitmap = [[NSImageRep alloc] imageRepWithContentsOfFile:filePath]; With the code shown, I get a runtime error: -[NSImageRep imageRepWithContentsOfFile:]: unrecognized selector sent to instance 0x100147070. I have tried replacing the second line of code with: NSImage *controlImage = [[NSImage alloc] initWithContentsOfFile:filePath]; NSBitmapImageRep *controlBitmap = [[NSBitmapImageRep alloc] initWithData:controlImage]; But this yields a compiler error 'incompatible type' saying that initWithData wants a NSData variable not an NSImage. I have also tried various other ways to get this done, but all are unsuccessful either due to compiler or runtime error. Can someone help me with this? I will eventually need to load some PNG files in the same way (so it would be nice to have a consistent technique for both). And if you know of an easier / simpler way to accomplish what I am trying to do (i.e., get the images into a two-dimensional array), rather than using NSBitmapImageRep, then please let me know! And by the way, I know the path is valid (confirmed with fileExistsAtPath) -- and the filename in outLabel is a file with .jpg extension. Thanks for any help!

  • Retrieving dll version info via Win32 - VerQueryValue(...) crashes under Win7 x64

    - by user256890
    The respected open source .NET wrapper implementation (SharpBITS) of Windows BITS services fails identifying the underlying BITS version under Win7 x64. Here is the source code that fails. NativeMethods are native Win32 calls wrapped by .NET methods and decorated via DllImport attribute. private static BitsVersion GetBitsVersion() { try { string fileName = Path.Combine( System.Environment.SystemDirectory, "qmgr.dll"); int handle = 0; int size = NativeMethods.GetFileVersionInfoSize(fileName, out handle); if (size == 0) return BitsVersion.Bits0_0; byte[] buffer = new byte[size]; if (!NativeMethods.GetFileVersionInfo(fileName, handle, size, buffer)) { return BitsVersion.Bits0_0; } IntPtr subBlock = IntPtr.Zero; uint len = 0; if (!NativeMethods.VerQueryValue(buffer, @"\VarFileInfo\Translation", out subBlock, out len)) { return BitsVersion.Bits0_0; } int block1 = Marshal.ReadInt16(subBlock); int block2 = Marshal.ReadInt16((IntPtr)((int)subBlock + 2 )); string spv = string.Format( @"\StringFileInfo\{0:X4}{1:X4}\ProductVersion", block1, block2); string versionInfo; if (!NativeMethods.VerQueryValue(buffer, spv, out versionInfo, out len)) { return BitsVersion.Bits0_0; } ... The implementation follows the MSDN instructions by the letter. Still during the second VerQueryValue(...) call, the application crashes and kills the debug session without hesitation. Just a little more debug info right before the crash: spv = "\StringFileInfo\040904B0\ProductVersion" buffer = byte[1900] - full with binary data block1 = 1033 block2 = 1200 I looked at the targeted "C:\Windows\System32\qmgr.dll" file (The implementation of BITS) via Windows. It says that the Product Version is 7.5.7600.16385. Instead of crashing, this value should return in the verionInfo string. Any advice?

  • How do I prevent a C# method from executing using an attribute validator?

    - by Boydski
    I'd like to create an attribute-based validator that goes a few steps beyond what I've seen in examples. It'll basically prevent methods or other functionality from executing. Please be aware that I'm having to use AzMan since I have no availability to Active Directory in this scenario. Here's some pseudo code of what what I'm looking for: // Attribute validator class AttributeUsage is arbitrary at this point and may include other items [AttributeUsage( AttributeTargets.Method | AttributeTargets.Property, AllowMultiple = true, Inherited = true )] public class PermissionsValidatorAttribute : Attribute { public PermissionsValidatorAttribute(PermissionEnumeration permission){...} public bool UserCanCreateAndEdit(){...} public bool UserCanDelete(){...} public bool UserCanUpload(){...} } Here's a sample of a class/member that'll be decorated. The method will not be executed at all if the PermissionValidator.UserCanDelete() doesn't return true from wherever it's executed: public class DoStuffNeedingPermissions { [PermissionValidator(PermissionEnumeration.MustHaveDeletePermission)] public void DeleteSomething(){...} } I know this is a simple, incomplete example. But you should get the gist of what I'm needing. Make the assumption that DeleteSomething() already exists and I'm preferring to NOT modify the code within the method at all. I'm currently looking at things like the Validation Application Block and am messing with custom attribute POC's. But I'd love to hear opinions with code samples from everyone out there. I'm also certainly not opposed to other methods of accomplishing the same thing such as extension methods or whatever may work to accomplish the same thing. Please remember I'm making the attempt to minimize changes to existing DoStuffNeedingPermissions code. Thanks everyone!

  • Pointers in C# to make int array?

    - by Joshua
    The following C++ program compiles and runs as expected: #include <stdio.h> int main(int argc, char* argv[]) { int* test = new int[10]; for (int i = 0; i < 10; i++) test[i] = i * 10; printf("%d \n", test[5]); // 50 printf("%d \n", 5[test]); // 50 return getchar(); } The closest C# simple example I could make for this question is: using System; class Program { unsafe static int Main(string[] args) { // error CS0029: Cannot implicitly convert type 'int[]' to 'int*' int* test = new int[10]; for (int i = 0; i < 10; i++) test[i] = i * 10; Console.WriteLine(test[5]); // 50 Console.WriteLine(5[test]); // Error return (int)Console.ReadKey().Key; } } So how do I make the pointer?

  • Calculate an Internet (aka IP, aka RFC791) checksum in C#

    - by Pat
    Interestingly, I can find implementations for the Internet Checksum in almost every language except C#. Does anyone have an implementation to share? Remember, the internet protocol specifies that: "The checksum field is the 16 bit one's complement of the one's complement sum of all 16 bit words in the header. For purposes of computing the checksum, the value of the checksum field is zero." More explanation can be found from Dr. Math. There are some efficiency pointers available, but that's not really a large concern for me at this point. Please include your tests! (Edit: Valid comment regarding testing someone else's code - but I am going off of the protocol and don't have test vectors of my own and would rather unit test it than put into production to see if it matches what is currently being used! ;-) Edit: Here are some unit tests that I came up with. They test an extension method which iterates through the entire byte collection. Please comment if you find fault in the tests. [TestMethod()] public void InternetChecksum_SimplestValidValue_ShouldMatch() { IEnumerable<byte> value = new byte[1]; // should work for any-length array of zeros ushort expected = 0xFFFF; ushort actual = value.InternetChecksum(); Assert.AreEqual(expected, actual); } [TestMethod()] public void InternetChecksum_ValidSingleByteExtreme_ShouldMatch() { IEnumerable<byte> value = new byte[]{0xFF}; ushort expected = 0xFF; ushort actual = value.InternetChecksum(); Assert.AreEqual(expected, actual); } [TestMethod()] public void InternetChecksum_ValidMultiByteExtrema_ShouldMatch() { IEnumerable<byte> value = new byte[] { 0x00, 0xFF }; ushort expected = 0xFF00; ushort actual = value.InternetChecksum(); Assert.AreEqual(expected, actual); }

  • Grouping a list of of entities which has a sublist in c#

    - by mikei
    I have a set of Entities which basically has this structure. {Stats Name="<Product name> (en)" TotalResources="10" ..} {DayStats Date="2009-12-10" TotalResources="5"} {DayStats Date="2009-12-11" TotalResources="5"} {Stats} {Stats Name="<Product name> (us)" TotalResources="10" ..} {DayStats Date="2009-12-10" TotalResources="5"} {DayStats Date="2009-12-11" TotalResources="5"} {Stats} ... What I wan't to extract from this set is a new set entities (or entity in the example above) where the first level has been grouped by the (ignoring the country label) where all/some of the properties has been summmed together, including the the sublist of {DayStas} on a per day basis. So the result set of the example would look something like this: {Stats Name="<Product name>" TotalResources="20" ..} {DayStats Date="2009-12-10" TotalResources="10"} {DayStats Date="2009-12-11" TotalResources="10"} {Stats} ... So my question is: Is it possible to do this in a more elegant way in LINQ rather than the vanilla "loop-trhough-each-entity-and-compare"-way? And I wan't the set to contain the same type of entities as the original set ({Stats}, {DayStats}), your answer doesn't need to include code for that, I can probably work that out by myself. Just letting you know incase you need to take that into account. (I'm sorry if this question has been discussed before, I tried searching to no avail. I guess my searching skills are fuubar ;)) Merry christmas =)

  • How to make a WPF ComboBox editable with custom values

    - by Liam
    I would like to have a combobox that allows selection from a list of values and also allow a custom value from the typed in text. For display reasons the items are a complex type (lets say the combobox item template displays a patch of color and a flag indicating if it is a custom color). public class ColorLevel { public decimal Intensity { get; set; } public bool IsCustom { get; set; } public Color BaseColor { get; set; } public override ToString() { return string.Format("{0}", Intensity*100); } } Example items var items = new [] { new ColorLevel { Intensity = 0.9m, IsCustom = false, BaseColor = Color.Red }, new ColorLevel { Intensity = 0.7m, IsCustom = false, BaseColor = Color.Red } } XAML <ComboBox SelectedItem="{Binding Path=SelectedColorLevel}" IsEditable="true" IsTextSearchEnabled="true"> </ComboBox> So the above markup works when an item is selected from the item list. And as you type with the text search the matching items are selected. If the typed text doesn't match an item then the SelectedColorLevel is set to null. The question is at what point (and how) is it best to create a new custom item that can be set to the SelectedColorLevel when the typed text doesn't match an item. For example I would want to assign a new item to the selected value such as new ColorLevel { Intensity = decimal.Parse(textvalue), IsCustom = true } or using an appropriate converter and databinding to the Text property.
