  • Can a program that controls IE detect if a HTTP 30x code is encountered?

    - by hillu
    I am trying to control an InternetExplorer.Application via the COM interface, using Perl, Win32::OLE, and information from MSDN. My goal is to get as good an idea as possible about what IE is doing. (Related to this question.) IE uses events to notify my program when it has finished various stages of processing a certain URL (NavigateComplete2, DownloadComplete DocumentComplete). It can also tell my program about various errors it encounters (NavigateError2). I consider that part of my problem solved well enough. I would also like to be able to reliably detect if IE is redirected by the server. Primarily, I'm concerned about HTTP 30x status codes. Is there a way to do this, either with COM automation or via another route?

  • Are there any syntax errors in the code snippet here?

    - by Mask
    typedef union YYSTYPE { int64_t iConst; // constant value float fConst; // constant value int iAttrLocator; // attribute locator (rowitem for int/float; offset+size for bits) int iFunc; // function id int iNode; // node index } YYSTYPE; It looks valid to me,but the cdt reports the following for the line int64_t iConst;: Multiple markers at this line: - syntax error before "int64_t" - no semicolon at the end of structure or union There are two files that defines int64_t,one is within the project itself(sphinxstd.h),the other is the MinGW/include/stdint.h,is it caused by this conflict?

  • How can I display a language according to the user's browser's language inside this code?

    - by janoChen
    How can I display a language according to the user's browser's language inside this mini-framework for my multilingual website? Basically, it has to display the default language of the user if there's no cookies. Example of index.php: (rendered output) <h2><?php echo l('tagline_h2'); ?></h2> common.php: (controller of which language to output) <?php session_start(); header('Cache-control: private'); // IE 6 FIX if(isSet($_GET['lang'])) { $lang = $_GET['lang']; // register the session and set the cookie $_SESSION['lang'] = $lang; setcookie("lang", $lang, time() + (3600 * 24 * 30)); } else if(isSet($_SESSION['lang'])) { $lang = $_SESSION['lang']; } else if(isSet($_COOKIE['lang'])) { $lang = $_COOKIE['lang']; } else { $lang = 'en'; } //use appropiate lang.xx.php file according to the value of the $lang switch ($lang) { case 'en': $lang_file = 'lang.en.php'; break; case 'es': $lang_file = 'lang.es.php'; break; case 'tw': $lang_file = 'lang.tw.php'; break; case 'cn': $lang_file = 'lang.cn.php'; break; default: $lang_file = 'lang.en.php'; } //translation helper function function l($translation) { global $lang; return $lang[$translation]; } include_once 'languages/'.$lang_file; ?> Example of /languages/lang.en.php: (where multilingual content is being stored) <?php $lang = array( 'tagline_h2' => '...',

  • How to add children of an ItemsControl where the children should decide their own position in Wpf?

    - by code-zoop
    Hey all I am using a wpf slider to display the time line in a video player. I need to add an ItemControl of some sort on top of this so that I can add buttons on the time line on certain positions in the time line (the buttons will hold their own position relative to the parent ItemsControl). What ItemsControl container should I use where I can add child elements that know their own position (based on their timecode)? I have looked at the different ItemsControls in Wpf, and it looks like all of them have a certain way to stack their children (Horizontal or vertical one after another)! And to add some more complexity, How can the positioning of the children be relative to the width of the parent ItemsControl? This way scaling up and down the ItemsContol will reposition the children! Thanks

  • Something is wrong with this C code to reverse string, but I dont know what ? please help

    - by Harbhag
    Hi all, I am beginnner to programming. I wrote this little program to reverse a string. But if I try to reverse a string which is less than 5 characters long then it gives wrong output. I cant seem to find whats wrong. #include<stdio.h> #include<string.h> int main() { char test[50]; char rtest[50]; int i, j=0; printf("Enter string : "); scanf("%s", test); int max = strlen(test) - 1; for ( i = max; i>=0; i--) { rtest[j] = test[i]; j++; } printf("Reversal is : %s\n", rtest); return 0; }

  • How can I tell if a set of parens in perl code will act as grouping parens or form a list?

    - by Ryan Thompson
    In perl, parentheses are used for overriding precedence (as in most programming languages) as well as for creating lists. How can I tell if a particular pair of parens will be treated as a grouping construct or a one-element list? For example, I'm pretty sure this is a scalar and not a one-element list: (1 + 1) But what about more complex expressions? Is there an easy way to tell?

  • null != null - any ideas on how to re-arrange the code or prevent this?

    - by Alex
    Currently debugging, and found an if-statement which for no (I thought...) reason gave me an NPE, obviously for a reason. Which seemed to be that the statement turned out to be if(false && (null != null || null != Color)). if(destination != null && (destination.getPiece() != null || destination.getPiece().getColour() != pieceColour)) - the if-statement Both destination can be null and piece can be. The getColour() method returns an attribute of type Color from piece, which must be null if the piece is null. The piece at destination has a different pieceColour attribute then the one in the if-statement. Specifically, how do I re-arrange (destination.getPiece() != null) ?

  • How can I get this code involving unique_ptr to compile?!

    - by Neil G
    #include <vector> #include <memory> using namespace std; class A { public: A(): i(new int) {} A(A const& a) = delete; A(A &&a): i(move(a.i)) {} unique_ptr<int> i; }; class AGroup { public: void AddA(A &&a) { a_.emplace_back(move(a)); } vector<A> a_; }; int main() { AGroup ag; ag.AddA(A()); return 0; } does not compile... (says that unique_ptr's copy constructor is deleted) I tried replacing move with forward. Not sure if I did it right, but it didn't work for me.

  • Regex to exclude 1 word out of a regex code.

    - by Mech Software
    I need a regex expert to help out on this one. Examples I've found on here and the net I cant seem to get right. I'm using PHP and I have the following regex expression /([^a-zA-Z0-9])GC([A-Z0-9]+)/ This matches items like GCABCD GC123A, etc. What i need to do is EXCLUDE GCSTATS from this. So basically I want it to work just as it has, except, ignore GCSTATS in the regex.

  • Why doesn't this Ruby on Rails code work as I intend it to?

    - by Justin Meltzer
    So I attempted to build what I asked about in this question: Fix voting mechanism However, this solution doesn't work. A user can still vote however many times he or she wants. How could I fix this and/or refactor? def create @video = Video.find(params[:video_id]) @vote = @video.video_votes.new @vote.user = current_user if params[:type] == "up" @vote.value = 1 else @vote.value = -1 end if @previous_vote.nil? if @vote.save respond_to do |format| format.html { redirect_to @video } format.js end else respond_to do |format| format.html { redirect_to @video } format.js {render 'fail_create.js.erb'} end end elsif @previous_vote.value == params[:type] @previous_vote.destroy else @previous_vote.destroy if @vote.save respond_to do |format| format.html { redirect_to @video } format.js end else respond_to do |format| format.html { redirect_to @video } format.js {render 'fail_create.js.erb'} end end end @previous_vote = VideoVote.where(:video_id => params[:video_id], :user_id => current_user.id).first end

  • Concatenation with Zero is not occurring properly in code?

    - by Vineet
    I was trying to reverse a number in PL/SQL. It's working fine, but when my number contains any 0, the output is unexpected. For example: 1234 output 4321 1000 output 1 1203 ouput 3021 10001 output 1 DECLARE r number(9); num number(9):=&p_num; BEGIN WHILE num>=1 LOOP IF mod(num,10)=0 THEN -- extracting last digit of a number . r:=r||0; --if end digit is 0 then concat r with 0 ELSE r:=r||mod(num,10);--if mod is not 0 then it would be last digit. END IF; num:=trunc(num/10);--Removing last digit from number END LOOP; dbms_output.put_line(r); END;

  • Entity Framework 4.0: Why Would One Use the Code Generated EntityObjects Over POCO Objects?

    - by senfo
    Aside from faster development time (Visual Studio 2010 beta 2 has no T4 templates for building POCO entity objects that I'm aware of), are there any advantages to using the traditional EntityObject entities that Entity Framework creates, by default? If Microsoft delivers a T4 template for building POCO objects, I'm trying to figure out why anybody would want to use the traditional method.

  • C# .net -> SQLite error: Unable to open the database file

    - by CODe
    Hello all, I'm getting "System.Data.SQLite.SQLiteException: Unable to open the database file." when I attempt to access the database to save a record upon the "first" opening of my program. Here's the thing, it works fine when debugging locally in Visual Studio, but stops working when I package the program in an installer, and then install the program somewhere. I was guessing that it was the location of the database, which I just have set at database.s3db without a path, because it is stored next to the program's exe, but how could that cause problems? I'm at a loss, any further ideas or suggestions for solving this problem would be greatly appreciated.

    - by gagneet
    I am working on a Macbook system , which is formatted as a case insensitive system. The issue is that, I need to check out a SVN branch which has some case sensitive files in it. Example: inbuilt-file.c InBuilt-File.c How do I checkout this branch when both the files are in the same folder? When I try and checkout, it gives me an error stating that an unversioned file of the name already exists.

  • Can you change VS Win Forms designer code generation?

    - by Big Endian
    We implemented new standards, which call for our private members to have a leading underscore. Like so: private System.Windows.Forms.Label _label; Unfortunately VS will put out the default below when you drag a new label onto your form: private System.Windows.Forms.Label label1; Is there a way to change that to: private System.Windows.Forms.Label _label1; Cheers, Plamen

  • What is the ambiguity in this piece of code?

    - by cambr
    #include <iostream> using namespace std; class A { public: void eat(){ cout<<"A";} }; class B: public A { public: void eat(){ cout<<"B";} }; class C: public A { public: void eat(){ cout<<"C";} }; class D: public B,C { public: void eat(){ cout<<"D";} }; int main(){ A *a = new D(); a->eat(); } I am not sure this is called diamond problem or not, but why doesn't this work? When I said, a->eat() (remember eat() is not virtual), there is only one possible eat() to call, that of A. Why then, do I get this error: 'A' is an ambiguous base of 'D'

  • How do I find a source code position from an address given by a crash in Window CE

    - by Shane MacLaughlin
    I have a Windows mobile 4.0 application, written using EVC++ 4.0 SP4 with MFC, that is exhibiting a random occasional crash in the field. e.g. Exception ox800000002 at 00112584. It does not happen under various emulators and simulators, hence is very difficult to trace using a debugger. The crash throws up and address and exception type. Given that I have the PDB is there any way to track this address to the source. I can't recompile using VC++ 8 as it doesn't support the mobile 4 SDK. My guess is that without a stack trace I'm not going to have much joy, as the chances are that the exception may not be in my source. Worth a try all the same. Edit As suggested, I have looked at the address in the context of the .MAP file for the program. This reveals the following Address Publics by Value Rva+Base Lib:Object 0001:00000000 ?GetUnduValue@@YANMM@Z 00011000 f 7Par.obj ' ' ' 0001:001124b8 ?OnLButtonUp@CGXGridUserDragSelectRangeImp@@UAAHPAVCGXGridCore@@AAVCPoint@@AAI@Z 001234b8 f gxseldrg.obj 0001:001126d8 ?OnSelDragStart@CGXGridUserDragSelectRangeImp@@UAAHPAVCGXGridCore@@KK@Z 001236d8 f gxseldrg.obj Which suggests the error occured during CGXGridUserDragSelectRangeImp::OnLButtonUp(), which seems a bit odd as I don't think there was a mouse / keyboard / screen button pressed at the time. Could be the stack got fragged before the crash got reported, and I'm wasting my time. I'll recompile with assembler output to try to isolate it to a given line, but don't hold out much hope :( Does the fact that the map file reports segmented addresses e.g. 0001:xxxxxxxxx and the crash report unsegmented addresses mean I have to carry out some computation to get the map address from the crash address?
