  • What is the purpose of using -pedantic in GCC/G++ compiler?

    - by huahsin68
    Hi, -ansi: tells the compiler to implement the ANSI language option. This turns off certain "features" of GCC which are incompatible with the ANSI standard. -pedantic: used in conjunction with -ansi, this tells the compiler to be adhere strictly to the ANSI standard, rejecting any code which is not compliant. Text above is extract from this note. First thing first, what is the purpose of usage of -pedantic and -ansi option with GCC/G++ compiler, I couldn't understand the above description. Can anyone tell me the circumstances of using the above two options? When should I use it? Is it important one? THanks @!

  • Codeigniter setting multiple where conditions, how to unset one

    - by Dustin
    I've got a script that is a notify_url from paypal that is supposed to update multiple tables in my database using the following code: //update first table $this-db-where('someid', $somid); $this-db-update('table', $data); ///update second table $this-db-where('somesecondid', $somesecondid) $this-db-update('anothertable', $data2); Then I get the following error: Unknown column 'somesecondid' in 'where clause' UPDATE anothertable SET avail = 0 WHERE someid = '13' AND somesecondid = '199' So codeigniter is combining those where clauses into a single query. Is there a way to unset the first one so it only has "UPDATE anothertable SET avail=0 WHERE somesecondid = 199" ? Thanks!

  • How to give 'Everybody' full rights to a file (programmatically)

    - by egrunin
    I'm modifying an old C++ program to run on Vista. It does not require Admin privileges. I've changed the code to put logfiles in \ProgramData\MyApp\. These logfiles are written with the stdio functions (fopen, fprintf, fclose). Here's the problem: UserA runs the program first, it creates \ProgramData\MyApp\MyLogFile.txt UserB runs the program next, it tries to append to MyLogFile.txt and gets access denied. I tried creating a null SECURITY_DESCRIPTOR and passing that to CreateFile(). That does create a file with "no permissions assigned", but it seems as if the first user to write to the file takes ownership and afterwards all the other non-admin users are out of luck. It's important that all users share the same logfiles, but it's also important that I change as little code as possible.

  • Create multiple columns on one sheet from 1 column on another with logic

    - by user450252
    I am new to VBA and I am struggling trying to make this work. I am in need of a macro that will process each cell\column on Sheet1 and put the results on Sheet2. I'm sure this is pretty easy for those who are more advanced with VB code. It contains many columns.. Anytime we encounter a — or an empty cell, we populate the cell with -999 (see the example on Sheet2) on the first column, which contains "0-2". Then we create 2 new columns and populate them with 0 on the first column and 2 on second column (see example on Sheet2). If a value is found on only one side, we then populate both sides with the same number. As each column is being process in Sheet1 and Sheet1: A B Column1 Column2 Title Title2 0–2 0–4 3 — — 5 — — — 10–23 11—29 And the results should look like this on Sheet2 Sheet2 A B C D Column1 Column1 Column2 Column2 Title-A Title-B Title-A Title-B 0 2 0 4 3 3 -999 -999 -999 -999 5 5 -999 -999 -999 -999 —999 -999 -999 -999 10 23 11 29

  • Combining packages from different projects into a single project in eclipse

    - by primal
    Hi, As part of the Android application I am developing in eclipse, I need to combine two packages from different projects into a single project. I tried copying the files in the package of the second project under the src folder of the first folder and copied other files required for second package into the res folder of the first project. But the auto-generated Java files i.e R.java doesn't get updated on copying. I tried right clicking on the project and clicking on Android Tools - Fix Project Properties. But nothing changed. Any pointers on what I am doing wrong much be appreciated.

  • MySQL/PHP: How to insert logged in user id into another table that is gathering data from a form tha

    - by Lisa
    For the first time I am needing to join information from two tables and am quite nervous about doing it without any advice first. Basically, I am building a secure site that is accessed by authorised users. I have my login table with user_id, username, password Once the user is on the site, they have the option of inputting data into another table called input. At the moment this table only captures the information that is entered, not the user_id or username of the inputter. I would like the form to be able to input the user_id and/or username from the login table into the input table. Please could somebody talk me through this process? I am sure that once this is amended, I will then be able to use the table to only allow the logged in user to access the information that he or she have inputted, is that correct? Many thanks

  • Rails + Passenger CSS problem

    - by Dan
    I'm trying to deploy my first Rails app. At first, I was getting the following error: ActionView::TemplateError (Permission denied) I set the permissions of the stylesheets folder to 777 (just for now until I work out what's going wrong) and the application started to work. However, it is not picking up any of the stylesheets (everything is displayed in plain text). If I view the source code and click the CSS links, I just get a blank page. Javascripts however, seem to be working just fine. VHost Config: <VirtualHost *:80> ServerName xxxx.xxx.com DocumentRoot /home/myapp/public <Directory /home/myapp/public> Allow from All AllowOverride all Options -MultiViews </Directory> </VirtualHost> Can anyone help? Any advice appreciated. Thanks.

  • Assign the results of a stored procedure into a variable in another stored procedure

    - by RHPT
    The title of this question is a bit misleading, but I couldn't summarize this very well. I have two stored procedures. The first stored procedure (s_proc1) calls a second stored procedure (s_proc2). I want to assign the value returned from s_proc2 to a variable in s_proc1. Currently, I'm calling s_proc2 (inside s_proc1) in this manner: EXEC s_proc2 @SiteID, @count = @PagingCount OUTPUT s_proc2 contains a dynamic query statement (for reasons I will not outline here). CREATE dbo.s_proc2 ( @siteID int, @count int OUTPUT ) AS DECLARE @sSQL nvarchar(100) DECLARE @xCount int SELECT @sSQL = 'SELECT COUNT(ID) FROM Authors' EXEC sp_ExecuteSQL @sSQL, N'@xCount int output', @xCount output SET @count = @xCount RETURN @count Will this result in @PagingCount having the value of @count? I ask because the result I am getting from s_proc1 is wonky. In fact, what I do get is two results. The first being @count, then the result of s_proc1 (which is incorrect). So, it makes me wonder if @PagingCount isn't being set properly. Thank you.

  • RegEx - character not before match

    - by danneth
    I understand the consepts of RegEx, but this is more or less the first time I've actually been trying to write some myself. As a part of a project, I'm attempting to parse out strings which match to a certain domain (actually an array of domains, but let's keep it simple). At first I started out with this: url.match('www.example.com') But I noticed I was also getting input like this: http://www.someothersite.com/page?ref=http://www.example.com These rows will ofcourse match for www.example.com but I wish to exclude them. So I was thinking along these lines: Only match rows that contain www.example.com, but not after a ? character. This is what I came up with: var reg = new RegExp("[^\\?]*" + url + "(\\.*)", "gi"); This does however not seem to work, any suggestions would be greatly appreciated as I fear I've used what little knowledge I yet possess in the matter.

  • Centre of a circle that intersects two points

    - by Jason
    Given two points in a 2D plane, and a circle of radius r that intersects both of those points, what would be the formula to calculate the centre of that circle? I realise there would two places the circle can be positioned. I would want the circle whose centre is encountered first in a clockwise direction when sweeping the line that joins the two points around one of those points, starting from an arbitrary angle. I guess that is the next stage in my problem, after I find an answer for the first part. I'm hoping the whole calculation can be done without trigonometry for speed. I'm starting with integer coordinates and will end with integer coordinates, if that helps.

  • strange bug - how to pause a java program?

    - by TerraNova993
    I'm trying to: display a text in a jLabel, wait for two seconds, then write a new text in the jLabel this should be simple, but I get a strange bug: the first text is never written, the application just waits for 2 seconds and then displays the final text. here is the example code: private void testButtonActionPerformed(java.awt.event.ActionEvent evt) { displayLabel.setText("Clicked!"); // first method with System timer /* long t0= System.currentTimeMillis(); long t1= System.currentTimeMillis(); do{ t1 = System.currentTimeMillis(); } while ((t1 - t0) < (2000)); */ // second method with thread.sleep() try { Thread.currentThread().sleep(2000); } catch (InterruptedException e) {} displayLabel.setText("STOP"); } with this code, the text "Clicked!" is never displayed. I just get a 2 seconds - pause and then the "STOP" text. I tried to use System timer with a loop, or Thread.sleep(), but both methods give the same result.

  • WPF Prism deactivate ?

    - by 2Fast4YouBR
    Hi all, I have an problem and would like to know if it is common problem or jsut with me. I am using Wpf with Prism and Unity, all with the pattern MvvM. I am loading a viewModel that has a reference to a dropdown with few items, my idea is that each time that the user click in some place to open the view that has this dropdown is that the dropdown will be shown with diferent values. The problem is that I see is that after I show the view for the first time and after the first DEACTIVATE, when I try to load it again looks like it is already in the memory (was not deactivated/disposed), so as is already in memory, it not call the constructor again of the modelView and the dropdown is shown with tha same old values. public BranchSelectionViewModel(IUnityContainer unityContainer) { this.unityContainer = unityContainer; User user = this.unityContainer.Resolve<User>(); this.branches = new ObservableCollection<Department>(user.Departments .Where(department => department.DepartmentId != user.SelectedDepartment.DepartmentId)); }

  • Using TDD: "top down" vs. "bottom up"

    - by Christian Mustica
    Since I'm a TDD newbie, I'm currently developing a tiny C# console application in order to practice (because practice makes perfect, right?). I started by making a simple sketchup of how the application could be organized (class-wise) and started developing all domain classes that I could identify, one by one (test first, of course). In the end, the classes have to be integrated together in order to make the application runnable, i.e. placing necessary code in the Main method which calls the necessary logic. However, I don't see how I can do this last integration step in a "test first" manner. I suppose I wouldn't be having these issues had I used a "top down" approach. The question is: how would I do that? Should I have started by testing the Main() method? If anyone could give me some pointers, it will be much appreciated.

  • Given a document select a relevant snippet.

    - by BCS
    When I ask a question here, the tool tips for the question returned by the auto search given the first little bit of the question, but a decent percentage of them don't give any text that is any more useful for understanding the question than the title. Does anyone have an idea about how to make a filter to trim out useless bits of a question? My first idea is to trim any leading sentences that contain only words in some list (for instance, stop words, plus words from the title, plus words from the SO corpus that have very weak correlation with tags, that is that are equally likely to occur in any question regardless of it's tags)

  • imageview draw issue with asynctask

    - by alexb
    Have the following asynctask that i'm using to download some images. Works fine except for the very first image, which doesn't always appears unless I do something like move to the next image and then back again. public class DownloadImageTask extends AsyncTask { static ImageView _imageView=null; public DownloadImageTask(ImageView ctl){ _imageView=ctl; } protected void onPostExecute(Bitmap result) { _imageView.setImageBitmap(result); } ... } I thought this might be an issue with updating the UI on a background thread, so I reworked this using an abstract class that invokes a method on the UI thread that calls .setImageBitmap() but I still get the same behaviour - works fine for all images except the first, unless I move to the next image and back again. Is there a way to force a redraw on the imageview after i set the image?

  • Best use of System.Windows.Forms.Application.Run()

    - by carlos
    Hello i Have a programa that has starts in a main sub, it executes some code and after that code it opens a form using System.Windows.Forms.Application.Run(General) General is a form but also a class, so I wonder what it the pros or cons of using : System.Windows.Forms.Application.Run(General) vs Dim gen as general System.Windows.Forms.Application.Run(gen) In the first I am opening a form using the name of the class, and I read that it is best to declare the instance as an object variable. So far I used the first approach without any problem. Thanks for your comments !

  • UITableView: Highlighted cell after switching back views

    - by Matthias
    Hi, I'm using a UINavController together with some UITableViews to display a kind of drill down for some data (e.g. like the Contact App). Works well. The only problem I have is, when I select a cell in the first table view it is highlighted, then the view switches to the next level and then, if I go back to the first level, the cell is still highlighted. So, how can I reset the highlighting when switching back? Thanks for your help. Regards Matthias

  • Why is .NET Post different from CURL? broken?

    - by ironnailpiercethesky
    I dont understand this. I ran this code below and the result json string was the link is expired (meaning invalid). However the curl code does the exact same thing and works. I either get the expected string with the url or it says i need to wait (for a few seconds to 1 minute). Why? whats the difference between the two? It looks very F%^&*ed up that it is behaving differently (its been causing me HOURS of problems). NOTE: the only cookie required by the site is SID (tested). It holds your session id. The first post activates it and the 2nd command checks the status with the returning json string. Feel free to set the CookieContainer to only use SID if you like. WARNING: you may want to change SID to a different value so other people arent activating it. Your may want to run the 2nd url to ensure the session id is not used and says expired/invalid before you start. additional note: with curl or in your browser if you do the POST command you can stick the sid in .NET cookie container and the 2nd command will work. But doing the first command (the POST data) will not work. This post function i have used for many other sites that require post and so far it has worked. Obviously checking the Method is a big deal and i see it is indeed POST when doing the first command. static void Main(string[] args) { var cookie = new CookieContainer(); PostData("http://uploading.com/files/get/37e36ed8/", "action=second_page&file_id=9134949&code=37e36ed8", cookie); Thread.Sleep(4000); var res = PostData("http://uploading.com/files/get/?JsHttpRequest=12719362769080-xml&action=get_link&file_id=9134949&code=37e36ed8&pass=undefined", null/*this makes it GET*/, cookie); Console.WriteLine(res); /* curl -b "SID=37468830" -A "DUMMY_User_Aggent" -d "action=second_page&file_id=9134949&code=37e36ed8" "http://uploading.com/files/get/37e36ed8/" curl -b "SID=37468830" -A "DUMMY_User_Aggent" "http://uploading.com/files/get/?JsHttpRequest=12719362769080-xml&action=get_link&file_id=9134949&code=37e36ed8&pass=undefined" */ }

I have web form with two options- File upload and textarea, i can easily pass file name with file upload options but have problem when it's textarea.

  • Will I use HtmlDocument even I want to parse the HTML string using HtmlAglityPack ?

    - by skhan
    Hi everyone, I'm working in C#. I'm trying to extract the first instance of img tag from a HTML string (which is actually a post data). This is my code: private string GrabImage(string htmlContent) { String firstImage; HtmlAgilityPack.HtmlDocument htmlDoc = new HtmlAgilityPack.HtmlDocument(); htmlDoc.LoadHtml(htmlContent); HtmlAgilityPack.HtmlNode imageNode = htmlDoc.DocumentNode.SelectSingleNode("//img"); if (imageNode != null) { return firstImage = imageNode.ToString(); } else return firstImage=" "; } But it gets null in htmlDoc, will I use the HtmlDocument type even if I'm trying to parse the HTML from a string ? P.S btw is it the correct way of grabbing the first instance of image tag from my HTML string?

  • How does C free() work?

    - by slee
    #include <stdio.h> #include <stdlib.h> int * alloc() { int *p = (int *)calloc(5,4); printf("%d\n",p); return p; } int main() { int *p = alloc(); free(p); printf("%d\n",p); p[0] = 1; p[1] = 2; printf("%d %d\n",p[0],p[1]); } As to the code segment, I allocate 5 ints,first. And then I free the memory. When I printf p, why does p sill have a value same to the memory address allocated first? And I also can assign value to p[0] and p[1]. Does this mean free() do nothing? Once I allocate memory, I can use later though I have freed it.
