  • Problem with array of elements of a structure type

    - by kobac
    I'm writing an app in Visual Studio C++ and I have problem with assigning values to the elements of the array, which is array of elements of structure type. Compiler is reporting syntax error for the assigning part of the code. Is it possible in anyway to assign elements of array which are of structure type? typedef struct { CString x; double y; } Point; Point p[3]; p[0] = {"first", 10.0}; p[1] = {"second", 20.0}; p[2] = {"third", 30.0};

  • Searching for a source code editor component

    - by Iso5786
    Hi, I have to develop a program at work in which a consultant can enter a specification which is developed 2 years ago here in house. So i can't really tell what it is about. But the editor should support some standard functionality such as syntax highlighting, auto completion and maybe search & replace. I've searched for Java components but didn't find a good solution which matches my requirements. Anybody knows a good component? It doesn't matter in which language it is written but I prefer Java.

  • storing an integral value in a pointer variable while declaration

    - by benjamin button
    int main() { int *d=0; printf("%d\n",*d); return 0; } this works fine. >cc legal.c > ./a.out 0 if i change the statement int *d=0; to int *d=1; i see the error. cc: "legal.c", line 6: error 1522: Cannot initialize a pointer with an integer constant other than zero. so its obvious that it will allow only zero.i want to know what happens inside the memory when we do this int *d=0 which is making it valid syntax. I am just asking this out of curiosity!

  • C/C++ enum and char * array

    - by Eric M
    Ran accross the following code in an article and didn't think it was standard C/C++ syntax for the char* array. As a test, both Visual C++ (visual studio 2005) and C++ Builder Rad XE both reject the 2nd line. Without using #defines, anyone have any tricks/tips for keeping enums and a string array sort of in sync without resorting to STL ? More of a curiosity question. enum TCOLOR { RED, GREEN, BLUE }; char *TNCOLOR[] = { [RED]="Red", [GREEN]="Green", [BLUE]="Blue" }; as an aside, the article this came from is quite old and I believe this might work under GCC but have not tested.

  • PHP Escaping from HTML, faster, cleanner?!

    - by rno
    I've read about it from the php website (http://us3.php.net/manual/en/language.basic-syntax.phpmode.php) Using: echo "<html tag>" is slower and also annoying because you got to escape char like " with \" But what's about using $output = <<< EOF <html code> EOF; Then later on in the code I can use $output .= <<< EOF <some more html code> EOF; then when I want to print it: echo "$output"; I think it's a great idea, but really wonder what you PHP guru think about it. Cheers, rno

  • Powershell and some simple string manipulation

    - by Pat
    need some help with building a powershell script to help with some basic string manipulation. I know just enough powershell to get in trouble, but can't figure out the syntax or coding to make this work. I have a text file that looks like this - Here is your list of servers: server1 server2.domain.local server3 Total number of servers: 3 I need to take that text file and drop the first and last lines (Always first and last.) Then I need to take every other line and basically turn it into a CSV file. The final output should be a text file that looks like this - server1,server2.domain.local,server3 Any suggestions on where to start? Thanks!

  • Databinding in windows forms on an object graph with possible null properties?

    - by Fredrik
    If I have an object graph like this: class Company { public Address MainAddress {...} } class Address { public string City { ... } } Company c = new Company(); c.MainAddress = new Address(); c.MainAddress.City = "Stockholm"; and databind to a control using: textBox1.DataBinding.Add( "Text", c, "MainAddress.City" ); Everything is fine, but If I bind to: Company c2 = new Company(); c2 using the same syntax it crashes since the MainAddress property is null. I wonder if there is a custom Binding class that can set up listeners for all the possible paths here and bind to the actual object dynamically when/if I sometime later in the application set the MainAddress property.

  • Regex: How to match a unix datestamp?

    - by Jono
    I'd like to be able to match this entire line (to highlight this sort of thing in vim): Fri Mar 18 14:10:23 ICT 2011. I'm trying to do it by finding a line that contains ICT 20 (first two digits of the year of the year), like this: syntax match myDate /^*ICT 20*$/, but I can't get it working. I'm very new to regex. Basically what I want to say: find a line that contains "ICT 20" and can have anything on either side of it, and match that whole line. Is there an easy way to do this?

  • Looking for marg_setValue fix in iPhoneOS

    - by John Smith
    I am trying to compile a library originally written for Cocoa. Things are good until it looks for the function marg_setValue(). It says there is a syntax error before char in marg_setValue(argumentList,argumentOffset,char,(char)lua_toboolean(state,luaArgument)); (it's talking about the third argument, not (char) ) I am trying to port LuaObjectiveCBridge to the iPhone. It has two choices, either using Runtime or Foundation. I have discovered there are some problems with foundation so I am trying runtime. But the compiler is not co-operating.

  • C inline assembly of x96 fbstp instruction

    - by David HUnter
    Was wondering how to inline a usage of fbstp on a 32 bit I86 architecture. I tried something like int main( ) { double foo = 100.0; long bar = 0; asm( "pushl %1; fbstp %0" : "=m"(bar) : "r"(foo) ); ... But bar is unchanged. I have tried reading everything I can find on this but most example simply do things like add two integers together. I can’t find any that talk about pushing operands onto the stack and what I should be doing when an instruction like fbstp writes 80 bits of data back to memory ( i.e. what C type to use ) and how to specify it in the asm syntax. Also on x86-64 there seems to be a pushq and no pushl but fbstp still exists whereas fbstq does not. Is there some other magic for 64 bit.

  • Vim or Emacs for software development

    - by Justin
    I'm not trying to start any wars here, just get some good info. I'm getting a little exhausted using numerous IDE's for development (VS, XCode, Eclipse/Netbeans, and TextMate) and am looking for a replacement I can use on all the different machines I interact with. What are some of the pros of Vim/Emacs for things like Languages supported Syntax highlighting (for things such as c, objc-c, c#, java, python, haskell, html, javascript, xml etc...) Code completion Code folding Working with a directory of files (like have a solution/project opened) Possible debugger support What are some of the main things you like about (Emacs/Vim, and please no flames only what you really like) Thanks =) *(yes.. I have scoured the net reading this vs that etc. but I'd like more of a 'why you love it' vs 'this is better than that because...')

  • Declaring STL Data Structures such as Vector in the .h

    - by sc_ray
    I am trying to declare a private Data Structure such as the Vector in my C++ header file which I want to eventually use within the method implementation of my .cpp. An example would be my header "SomeClass.h" where I have: class SomeClass { private: Vector<T> myVector; public: void AddTtoMyVector(T add); } And in my .cpp which is "SomeClass.cpp", I have the following: #include "SomeClass.h" SomeClass::AddTtoMyVector(T add) { myVector.Push_back(add); } Would the syntax here work? Or is there a different way of declaring and populating such structures?

  • Clean install of IIS 6 on Windows Server 2003 ignoring 'web.config'?

    - by Vario
    Hi, Any help with this would be really appreciated! As the title suggests, I'm running a brand new install of Windows Server 2003 and IIS 6 and I'm basically attempting to mirror a live web server onto a new internal development server, which runs the same setup. It's an ASP.NET site that relies heavily on URL rewriting (using Intelligencia). ASP.NET is set to run on v2.0.50727 on both servers. I've tried intentionally introduce syntax errors into the web.config and it just appears to be ignoring them completely, so given IIS 6 doesn't read the web.config, the rest of the site doesn't work at all (I get a 404 error, as a 'Default.aspx' doesn't exist since the web.config handles the default page rewriting). Having looked at the Application Mapping, '.config' files are set to use the default 'c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll' which exists. Is there anything else I may be missing? Thanks in advance.

  • How do I configure emacs for editing HTML files that contain Javascript?

    - by MakeDummy
    I have started the painful first steps of using emacs to edit an HTML file with both HTML tags and javascript content. I have installed nxhtml and tried using it - i.e set up to use nxhtml-mumamo-mode for .html files. But I am not loving it. When I am editing the Javascript portion of the code the tab indents do not behave as they do when editing C/C++ code. It starts putting tabs within the line and if you try and hit tab in the white space preceding a line it inserts the tab rather than re-tabifying the line. Another aspect that I don't like is that it doesn't do syntax colouring like the usual C/C++ modes do. I much prefer the behaviour of the default java-mode when editing HTML files but that doesn't play nicely with the HTML code. :-( 1) Is there a better mode for editing HTML files with Javascript portions? 2) Is there a way to get nxhtml to use the default java-mode for the javascript portions? Regards, M

  • IntelliJ doesn't seem to pickup certain sbt libraries, no code completion

    - by Blankman
    I am using sbt console in my terminal to compile my scala/play project. I am using intellij to edit my source code, basically using it just for getting some code completion and navigation etc. For some reason certain libraries don't seem to load correctly. For example, I added elastic search to my Dependancies.scala file, reloaded sbt and everything compiles fine but for some reason IntelliJ doesn't pickup the jars correctly i.e. they are in red and there is no syntax completion. How can I fix this? I tried shutting intellij down and restarting it but the problem remains. I am using Intelli 13.1.3 (ultimate)

  • Adding global blank option to DroDownList in MVC

    - by Diegos Grace
    Is there a way of using a templated helper in mvc so that each and every select list in my project has a custom default 'Choose an option' with null value etc. The posts I have seen seem a little complex, is it possible to have a DropDownList.ascx file in shared view folder with something like this: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<SelectListItem>>" %> <%= Html.DropDownList(selectlist name, selectlist value, "Choose an option")%> And then having a UIHint("DropDownList") for each dropdownlist in the ViewModel? Some guidance on syntax of parameters would be much appreciated, where name and value of the viewmodel dropdownlist plus the 'Choose an option' string are passed. Or is this all wishful thinking?

  • What is the correct way to reference RDFa namespaces in HTML5?

    - by Eivind Eidheim Elseth
    I'm setting up a HTML5 webpage and want to include RDFa. I try checking the syntax with the w3 validator, and check the extracted RDF using the w3 RDFa distiller. When I declare namespaces using xmlns:<ns>="<uri>" the validator complains that the attribute is not allowed there, and the specs say that xmlns is deprecated, but if I try the other suggested prefix="<ns> <uri>" the distiller doesn't discover the RDFa embedded on my page. Which way should I stick to?

  • PHP Populating array with $variables

    - by Tom
    Hi, I'm trying to create a basic shopping cart, having an issue with the product page allowing users to add more items to their cart then are in stock (I have code in place to prevent this on the view cart page, just not the view product page) This is what I have so far; for ($i = 0; $i < $numItem; $i++) { extract($cartContent[$i]); $subTotal += $price * $cartQuantity; $cartLimiter[$itemNo => $cartQuantity]; Using an array so the position number becomes the item number and the cart quantity becomes the assigned value, however it doesn't seem to like it and throws out on the bottom line of code: Parse error: syntax error, unexpected T_DOUBLE_ARROW, expecting ']' Thanks

  • Which is faster when animating the UI: a Control or a Picture?

    - by Christopher Walker
    /I'm working with and testing on a computer that is built with the following: {1 GB RAM (now 1.5 GB), 1.7 GHz Intel Pentium Processor, ATI Mobility Radeon X600 GFX} I need scale / transform controls and make it flow smoothly. Currently I'm manipulating the size and location of a control every 24-33ms (30fps), ±3px. When I add a 'fade' effect to an image, it fades in and out smoothly, but it is only 25x25 px in size. The control is 450x75 px to 450x250 px in size. In 2D games such as Bejeweled 3, the sprites animate with no choppy animation. So as the title would suggest: which is easier/faster on the processor: animating a bitmap (rendering it to the parent control during animation) or animating the control it's self?

  • Crystal Report Function for converting Seconds to Timespan format.

    - by arakkots
    I have a crystal report where it shows the Agent's activities throughout the day with a pie chart. In the details section it is displaying: Activity [string] StartedAt [DateTime] EndedAt [DateTime] Duration [The difference between EndedAt and StartedAt in seconds - Integer] Report data is GroupedBy Activity and summarized by Duration. Currently Duration is shown in seconds but I need to format it 02h:30m:22s:15ms. For that I wrote a custom function in Crystal Report in the Formula Workshop editor as follows, but it looks like the syntax is not right (Error message on keyword Long: "A variable type (for example, 'String') is missing."). Can someone help? Function GetTimeSpanString(seconds as Long) Dim ts As TimeSpan = TimeSpan.FromSeconds( seconds ); GetTimeSpan = string.Format("{0:D2}h:{1:D2}m:{2:D2}s:{3:D3}ms", ts.Hours, ts.Minutes, ts.Seconds, ts.Milliseconds) End Function

  • Increasing the JVM maximum heap size for memory intensive applications

    - by Alceu Costa
    I need to run a Java memory intensive application that uses more than 2GB, but I am having problems to increase the heap maximum size. So far, I have tried the following approaches: Setting the -Xmx parameter, e.g. -Xmx3000m. This approaches fails at the creation of the JVM. From what I've googled, it looks like that -Xmx must be less than 2GB. Using the -XX:+AggressiveHeap option. When I try this approach I get an 'Not enough memory' error that tells that the heap size is 1273.4 MB, even though my computer has 8GB of memory. Is there another approach that I can try to increase the maximum heap size of the JVM? Here's a summary of the computer specs: OS: Windows 7 (64 bit) Processor: Intel Core i7 (2.66 GHz) Memory: 8 GB

  • Open source C compiler in C#?

    - by Dinah
    I've been getting into compiler creation. I've found some terrific beginner stuff and advanced stuff but nothing in the middle. I've created 3 different simple proof-of-concept compilers for toy languages but I want to expose myself to something real. The most straight forward real language in terms of syntax seems to be C. Since the language I'm most comfortable with right now is C#, I'd love to study the source code of a real non-tutorial C compiler written in C#. Does one (with source code available) exist?
