  • int[] to string c#

    - by Robin Webdev
    Hi I'm developing an client application in C# and the server is written in c++ the server uses: inline void StrToInts(int *pInts, int Num, const char *pStr) { int Index = 0; while(Num) { char aBuf[4] = {0,0,0,0}; for(int c = 0; c < 4 && pStr[Index]; c++, Index++) aBuf[c] = pStr[Index]; *pInts = ((aBuf[0]+128)<<24)|((aBuf[1]+128)<<16)|((aBuf[2]+128)<<8)|(aBuf[3]+128); pInts++; Num--; } // null terminate pInts[-1] &= 0xffffff00; } to convert an string to int[] in my c# client i recieve: int[4] { -14240, -12938, -16988, -8832 } How do I convert the array back to an string? I don't want to use unsafe code (e.g. pointers) Any of my tries resulted in unreadable strings.

  • Using xval with fields containing periods

    - by JP
    Hello, I have been using xVal with success for a while but this evening ran into an issue where a field containing a period would not be validated (client or server-side). I am using ASP.NET MVC2 and need to use the period syntax in cases where I am model binding to a list. In the below example I am using a textbox for the sake of simplicity: xVal.AttachValidator(null, { "Fields": [{ "FieldName": "entry[622592].Value", "FieldRules": [{ "RuleName": "Required", "RuleParameters": {}}]}] }, {}) <input type="text" class="text" name="entry[622592].Value"/> If I replace both instances of "entry[622592].Value" to something trivial like "test" then the validation works successfully, but if i leave it this way the validation never appears to fire... Has anyone run into this issue? Thanks in advance!

  • ftp : get list of files

    - by Rohan
    I am trying to get a list of files on FTP folder. The code was working when I ran it locally, but on deploying it I started receiving html instead of file name ArrayList fName = new ArrayList(); try { StringBuilder result = new StringBuilder(); //create the directory FtpWebRequest requestDir = (FtpWebRequest)FtpWebRequest.Create(new Uri(directory)); requestDir.Method = WebRequestMethods.Ftp.ListDirectory; requestDir.Credentials = new NetworkCredential(FTP_USER_NAME, FTP_PASSWORD); requestDir.UsePassive = true; requestDir.UseBinary = true; requestDir.KeepAlive = false; requestDir.Proxy = null; FtpWebResponse response = (FtpWebResponse)requestDir.GetResponse(); Stream ftpStream = response.GetResponseStream(); StreamReader reader = new StreamReader(ftpStream, Encoding.ASCII); while (!reader.EndOfStream) { fName.Add(reader.ReadLine().ToString()); } response.Close(); ftpStream.Close(); reader.Close();

  • How to see "anti if" movement and its gaol?

    - by Vijay Shanker
    I have a developer for last 3 years, have been using if-else or if-else if statements a lot in my programing habit. And today, I found This link. One obvious sample i put here public void doSomthing(String target, String object){ //validate requests if(target != null && target.trim().length() < 1){ //invalid request; } //further logic } Now, I have seen this sort of check all over the places, libraries. So, I wanted to have a discussion about the worthiness of such a movement. Please let me know your views.

  • T-SQL Add Column In Specific Order

    - by Aren B
    Im a bit new to T-SQL, Coming from a MySQL background Im still adapting to the different nuances in the syntax. Im looking to add a new column AFTER a specific one. I've found out that AFTER is a valid keyword but I don't think it's the right one for the job. ALTER TABLE [dbo].[InvStockStatus] ADD [Abbreviation] [nvarchar](32) DEFAULT '' NOT NULL ; This is my current query, which works well, except it adds the field at the end of the Table, Id prefer to add it after [Name]. What's the syntax im looking for to represent this?

  • Sorting related objects in the Django Admin form interface

    - by Carver
    I am looking to sort the related objects that show up when editing an object using the admin form. So for example, I would like to take the following object: class Person(models.Model): first_name = models.CharField( ... ) last_name = models.CharField( ... ) hero = models.ForeignKey( 'self', null=True, blank=True ) and edit the first name, last name and hero using the admin interface. I want to sort the objects as they show up in the drop down by last name, first name (ascending). How do I do that? Context I'm using Django v1.1. I started by looking for help in the django admin docs, but didn't find the solution As you can see in the example, the foreign key is pointing to itself, but I expect it would be the same as pointing to a different model object. Bonus points for being able to filter the related objects, too (eg~ only allow selecting a hero with the same first name)

  • Help Fix a bug - Unexpected T_STRING

    - by thecoshman
    So I have just rebuilt my server, just on local network. Stick my site back on it, try to run the code, and I get a anice T_STRING error. This is all very strange, as I have not changed the code :S <?php $window_ID = -1; if(isset($_POST["window_ID"]) AND $_POST["window_ID"] != null){ $window_ID = trim($_POST["window_ID"]); } ?> This is the start of the file, apter this rather loverly snipit of PHP the rest is just XMl, yet on line 6 appertnlty there is an unexpected T_STRING, which is strange considering all that is on that line is the ?>, then the XML starts up... Any one got any ideas what has gone wrong here? Any chance it ould be magic quotes? I had turned it of before, but I want to now update my code to check for the magic quotes and avoid its stupid actions.

  • setCursor on container without it changing cursor of sub components

    - by Mike
    JPanel panel = new JPanel(null); panel.setSize(400, 400); panel.add(new JButton("Test")); panel.setCursor(Cursor.getCursor(Cursor.SOMETHING_SOMETHING_CURSOR)); The panel will have a custom cursor, but I don't want the button to have a custom cursor. I don't want to have to set the cursor of every sub component, because in my application I have many and I don't want to litter the code with setCursor statements. Is there a way, like overriding a method on the JPanel or something? A "contains" method somewhere is used to determine if a cursor needs to be set. Could I fool it into thinking the mouse is not in the container if it's really in a sub component? Any other nifty little trick?

  • Struggling to "clear" a CGLayer -- can it even be done?

    - by Joe Blow
    So I'm doing this repetitively - making a CGLayer, doing some processing, and then releasing it. This happens a lot in real time -- so surely there is a lot of overhead in making a whole new CGLayer each time? Surely it would be better to just keep lair around, and start fresh each time? However, I do not know any way, at all, to "erase" or "start from blank" a CGLayer?? Can anyone help on this? There is a function CGContextBeginPath(cc) but it's confusing: it seems to only clear out "that" path, it does not erase all of the CGLayer back to a blank canvas. how to return a CGLayer to a blank canvas????? Does anyone know? CGLayerRef lair = CGLayerCreateWithContext( UIGraphicsGetCurrentContext(), CGSizeMake(1024,768), NULL); CGContextRef cc = CGLayerGetContext(ether); // various processing here CGContextAddPath(cc, somePath); // various processing here CGLayerRelease(lair); Any ideas?!

  • Understanding linear linked list

    - by ArtWorkAD
    Hi, I have some problems understanding the linear linked list data structure. This is how I define a list element: class Node{ Object data; Node link; public Node(Object pData, Node pLink){ this.data = pData; this.link = pLink; } } To keep it simple we say that a list are linked nodes so we do not need to define a class list (recursion principle). My problem is that I am really confused in understanding how nodes are connected, more precisely the sequence of the nodes when we connect them. Node n1 = new Node(new Integer(2), null); Node n2 = new Node(new Integer(1), n1); What is link? Is it the previous or the next element? Any other suggestions to help me understanding this data structure?

  • Would like help with LOGON Trigger

    - by Risho
    I've created a logon trigger in MS SQL that needs to check dm_exec_sessions for a login. This login is the user listed in the connection string and has owner right to the database. If the login is verified, I need it to update a specific table and send an email. So far I've done just the following piece and it disabled my web site. The error I get is: "Logon failed for login 'dev' due to trigger execution. Changed database context to 'mydatabase'. Changed language setting to us_english." Any idea what I did wrong? Thanks, Risho CREATE TRIGGER TDY_Assets_Notification ON ALL SERVER WITH EXECUTE AS 'dev' FOR LOGON AS BEGIN IF ORIGINAL_LOGIN()='dev' AND (SELECT COUNT(*) FROM sys.dm_exec_sessions WHERE is_user_process = 1 AND original_login_name = 'dev') > 1 UPDATE Assets_TDY SET Suspense = 1, Warning = 1 WHERE (Date_Returned IS NULL) AND (GETDATE() >= DATEADD(day, 3, Date_Return)) END

  • System.NullReferenceException with WhoCanHelpMe Unit Test

    - by tlum
    I'm working with a test project based on WhoCanHelpMe, which is based on Sharp Architecture, NHibernateValidator, etc. As its written the when_the_profile_tasks_is_asked_to_create_a_profile unit test creates the profile object and saves it without issue. Now the profile object is a CreateProfileDetails type that derives from their own ValidatableValueObject which inherits the IValidatable interface. The problem surfaces when my class is based on an Entity rather than their ValidatableValueObject. When the test is run a System.NullReferenceException because Validate() is null. I'm afraid that I'm at a loss to resolve this bad behavior. Does anyone have some suggestions to get to the bottom of this? Thanks, -Ted-

  • Building a linked list with LINQ

    - by FreshCode
    What is the fastest way to order an unordered list of elements by predecessor (or parent) element index using LINQ? Each element has a unique ID and the ID of that element's predecessor (or parent) element, from which a linked list can be built to represent an ordered state. Example ID | Predecessor's ID --------|-------------------- 20 | 81 81 | NULL 65 | 12 12 | 20 120 | 65 The sorted order is {81, 20, 12, 65, 120}. An (ordered) linked list can easily be assembled iteratively from these elements, but can it be done in fewer LINQ statements? Edit: I should have specified that IDs are not necessarily sequential. I chose 1 to 5 for simplicity. See updated element indices which are random.

  • C#: Searching through arrays

    - by Jonathan Oberhaus
    I have a dvd app that stores dvds and blu-rays, I want to search the arrays by director. Below is the code for the inventory class I have seen many different ways to do this. There seems to be some debate as the best/most efficient way to accomplish this, any suggestions?

  • How to generate all permutations of a string in PHP ?

    - by Johan
    I need an algorithm that return all possible combination of all characters in one string. I've tried: $langd = strlen($input); for($i = 0;$i < $langd; $i++){ $tempStrang = NULL; $tempStrang .= substr($input, $i, 1); for($j = $i+1, $k=0; $k < $langd; $k++, $j++){ if($j > $langd) $j = 0; $tempStrang .= substr($input, $j, 1); } $myarray[] = $tempStrang; } But that only returns the same amount combination as the length of the string. Say the $input is = "hey", the result would be: hey, hye, eyh, ehy, yhe, yeh.

  • How to use a Visual C++ .Net String type as argument in a function

    - by stefangachter
    Probably this is not a difficult question, but I am always a little bit confused on how to treat String type as an argument in Visual C++. I have the following to functions: void function_1(String ^str_1) { str_1 = gcnew String("Test"); } void function_2() { String ^str_2 = nullptr; function_1(str_2); } After calling function_1, str_2 is still equal to null, but what I want to achieve is that str_2 is equal to Test. So, how can I achieve that the content of str_1 is passed to function_2? Thanks for any advice.

  • UIView animations on a path not linear

    - by chis54
    I have an iOS application that I want to animate a falling leaf (or several). I have my leaf image in an ImageView and I've figured out a simple animation from the documentation: [UIView animateWithDuration:4.0f delay:0 options:UIViewAnimationTransitionFlipFromLeft animations:^(void) { leaf1ImageView.frame = CGRectMake(320, 480, leaf1ImageView.frame.size.width,leaf1ImageView.frame.size.height); } completion:NULL]; This will make the leaf go from its starting position to the bottom right corner in a straight line. How would I animate this to follow a path or curve like a parabola or sinusoid and maybe even rotate the image or view? Would this be done in the animations block? Thanks in advance!

  • Action method expected parameter named Id and nothing otherwise

    The Error The parameters dictionary contains a null entry for parameter 'UserId' of non-nullable type 'System.Int64' for method 'System.Web.Mvc.ActionResult Predict(Int64)' in 'sportingbiz.Controllers.PredictionController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter. Parameter name: parameters This does not work. Throws the error mentioned above http://mysite/User/Profile/15 This works http://mysite/User/Profile/?UserID=15 The Controller Action public ActionResult Profile(long UserID) { } When I changed the parameter name to Id it works. I think it's because Id was specified in the route collection (Global.asax). Is it possible to tell MVC that UserId should map to Id without changing it in the Global.asax
