• How to copy QT folder to another folder without reinstalling it?

  - by Oleg

  I have QT installed on disc D (on Windows). And I want to move it to disc C. Is it possible to do that? If I just copy QT folder from C to D then I see lot of errors when I compile my applications that use QT. Errors are because qmake.exe contains full paths to include, bin and libs folders inside. So, when I create solution for Visual Studio 2005 using qmake - then this solution contains dependencies to old QT folder from disc D. And I found no way how to remove this dependencies without reinstalling of QT. It is not a big problem for one my single machine - I can reinstall. But I need to deliver this change then to tens and hundreds of other developers machines and I want to make it as easy as possible without need to reinstall QT.

• How to search for a string including spaces in Objective C?

  - by AlexCu

  I have a real basic command-line program, in Objective-C, that searches for user inputed information. Unfourtunately, the code will only read the first word in series of words that the user enters. For example, if the user enters in "Apples are great", only "Apples" is kept (and hence searched later on), excluding the "are great" part of the sentence. Here's what I have so far: char enteredQuery [128]; // array 'name' to hold the scanf string NSString *searchQuery; // ending NSString to hold and compare the user inputed data NSLog(@"Enter search query:"); scanf("%s", enteredQuery); //will read the next line searchQuery = [NSString stringWithCString: enteredQuery encoding: NSASCIIStringEncoding]; //converts scanf data into a NSString type I know it's got to do with me using scanf or the character-encoder conversion, but I can't seem to figure it out. Any help in solving the problem is very appreciated! Thanks.

• What will be the setup process for website development?

  - by Vijay Shanker

  Hi, I want to create a simple site for my personal usage. And this only in python based technologies. So I want to get a expert oponian on this topic. What should i used as platform? I did a search for available options and found Django, grok, web2py and many more of these. Which one a novice use should use? If I choose to use only the basic python scripts then what option i have to work on? http://wiki.python.org/moin/WebBrowserProgramming. This link on python site confused me more, instead of solving my curiosity about the topic. Please give some pointer to accurate and easy to understand reading materials. I have got a idea of developing java based web applications using either spring-webmvc and struts. Can I relate Java process to python process for web development?

• Which is the best Linux C/C++ debugger (or front-end to gdb) to help teaching programming?

  - by omer.gimenez

  I teach a sort of "lite" C++ programming course to novices ("lite" meaning no pointers, no classes, just plain old C, plus references and STL string and vectors). Students have no previous experience in programming, so I believe that using an interactive debugger would help them understand program flow, variables, and recursion. The course is taught in Linux. Teaching them to use gdb is just overkill (they will not use nor understand most features). I just need something simple but easy to use: to see at which line the program is now, what is in the stack (local variables, previous calls, etc.). I look something similar to old Turbo Pascal or Turbo C++ Borland's debugger, or Visual Studio debugger. Thank you,

• How do you open a second WPF window without creating a new one.

  - by Daniel

  In the program I am trying to build, I have a menu button that opens a second window. The user puts information into the second window, presses the "Done" button, and the information is transfered into the main window. The problem I am having is opening the second window. I have both windows build in xaml files in Visual Studio but I can't find a way to show the second window. Using "Window window = new Window" does not fit my needs because 1) I already have the second window built and 2) I have tried this and I cannot figure out how to add children to the window; there is no window.children nor any grid to put the children into. Thank you in advance!

• Still not understanding SVN Repositories in eclipse

  - by jax

  I am about to import my project into svn but don't want to stuff it up. My structure is like this: Repositories: /var/svn/client_name1/ /var/svn/client_name2/ Project directories under /var/svn/client_name1/ project1/ trunk/ branches/ tags/ project2/ trunk/ branches/ tags/ My Apache config looks like this: <Location /svn> DAV svn SVNParentPath /var/svn SVNListParentPath on AuthType Basic AuthName "My Repository" AuthUserFile /etc/svnpass Require valid-user AuthzSVNAccessFile /etc/svnauth </Location> Now I can access my svn repository http://mysite.com/svn/client_name1/ however, there are no projects displayed here, just a Revision 0 message (is that correct)? I can connect to the repository in eclipse using the same url. If I want to place an existing project into the repository what url do I use? http://mysite.com/svn/client_name1/project1 OR http://mysite.com/svn/client_name1/project1/trunk

• Accessing HttpApplication.Application variables from a class

  - by Young Ninja

  I set up various global parameters in Global.asax, as such: Application["PagePolicies"] = "~/Lab/Policies.aspx"; Application["PageShare"] = "/Share.aspx"; Application["FileSearchQueries"] = Server.MapPath("~/Resources/SearchQueries.xml"); ... I have no problem accessing these variables form .ascx.cs or .aspx.cs file -- ie. files that are part of the Web content. However, I can't seem to access 'Application' from basic class objects (ie. standalone .cs files). I read somewhere to use a slight variations in .cs files, as follows, but it always comes throws an exception when in use: String file = (String)System.Web.HttpContext.Current.Application["FileSearchQueries"];

• Generics and reflection in Java

  - by Ragesh

  This is probably a very basic question, but I'm really new to generics in Java and I'm having a hard time altering my thought process from the way things are done in C#, so bear with me. I'm trying to build a generic repository in Java. I've created an IRepository interface that looks like this: public interface IRepository<T extends IEntity> And a Repository class that looks like this: public class Repository<T extends IEntity> implements IRepository<T> Now, from within the constructor of my Repository class, I'd like to be able to "divine" the exact type of T. For example, if I instantiated a repository like this: IRepository<MyClass> repo = new Repository<MyClass>(); I'd like to know that T is actually MyClass. This is trivial in C#, but obviously generics are a totally different beast in Java and I can't seem to find anything that would help me do this.

• Automate publishing of a WCF library using MSBuild

  - by user438334

  I searched and couldn't find anything releated to this topic. When using Visual Studio 2010 for a WCF library, you can right-click it and publish the WCF Library, which generates/creates the .svc and web.config file as well as deploys it. I have been trying to mimic this in msbuild and have had no success. Is this possible? I have build scripts to deploy a WCF application, website, and have had no luck using these scripts to successfully deploy a WCF library. When i do use them, it compiles the Dll's but not the .svc or web.config file. Any advice would be greatly appreciated.

• Windows Phone 7, download xml over ssl with authentication

  - by Snake

  Hi, I'm trying to download a file from my provider. The url is protected with basic username and password, and everything is sent over ssl. So I try to do this: WebClient proxy = new WebClient(); proxy.DownloadStringCompleted += (o, dscea) => System.Diagnostics.Debugger.Break(); proxy.Credentials = new NetworkCredential("username", "password"); proxy.DownloadStringAsync(new Uri("https://..../.../data.xml")); As you can see I try to validate.

• overflow technique in stack

  - by metashockwave

  int main(void) { problem2(); } void doit2(void) { int overflowme[16]; //overflowme[37] =0; } void problem2(void) { int x = 42; doit2(); printf("x is %d\n", x); printf("the address of x is 0x%x\n", &x); } Would someone help me understand why overflowme[37] =0; from the doit2 function will overwrite the value of x? (please include Program Counter and Frame Pointer of the function doit2 in your explanation) Thank you! It works every time with Project properties-Configuration properties-C/C++ -Code Generation-Basic Runtime Checks set to "Default". so it's not an undefined behavior.

• Force Response to Download File(s) to Desktop with Ruby?

  - by viatropos

  I was thinking about making a little crop/resize batch processor online, and wanted to know if there was a way for me to do the following: upload image and specify dimensions click "process" and remote app resizes image image downloads automatically locally to wherever it was I uploaded it (say from my desktop), but with a new name (based on the time for example). This would make it so I could host a free image processor that never stored any data other than tempfiles. Is that possible? Something like Rails' send_file method, but I'm using Sinatra and am looking for something in pure ruby. What's the basic concept behind this? What if I wanted to do this for multiple files? Åssuming I can get multiple files uploaded no problem, how can I download all of them automatically?

• updating a shape in scene with a for loop using javafx

  - by Susanta

  Following is a code fragment. I am updating a rectangle using a for loop when a button is pressed. This is a model for my ultimate intention of showing visualization of data model as it changes large number of times inside a for loop. It works but I see only one change. Now since I am changing the width randomly I should see large number of changes. It seems I am making a wrong assumption on something basic. The code goes below: 7 var rec: Rectangle = Rectangle { 8 x: 10, y: 10 9 width: 140, height: 90 10 fill: Color.BLACK 11 } 12 13 Stage { 14 title: "MyApp" 15 scene: Scene { 16 width: 200 17 height: 200 18 content: [ 19 rec, 20 Button { 21 text: "Button" 22 action: function () { 23 for (i in [1..999]) { 24 rec.width = 25 + java.lang.Math.random()*50; 25 } 26 } 27 } 28 ] 29 } 30 }

• How to handle "100 continue" HTTP message ?

  - by Stephane

  Hello, I'm writing a simplistic HTTP server that will accept PUT requests mostly from cURL as client and I'm having a bit of an issue with handling the "Expect: 100-continue" header. As I understand it, the server is supposed to read the header, send back a "HTTP/1.1 100 Continue" response on the connection, read the stream up to the value on "Content-Length" and then send back the real response code (Usually "HTTP/1.1 200 OK" but any other valid HTTP answer should do). Well, that's exactly what my server does. The problem is that, apparently, if I send a "100 Continue" answer, cURL fails to report any subsequent HTTP error code and assumes the upload was a success. For instance, if the upload is rejected due to the nature of the content (there is a basic data check happening), I want the calling client to detect the problem and act accordingly. Am I missing something obvious ? Thanks

• Formula for Live Video Streaming Bitrate

  - by MD

  I am simply looking for the formula that should be used here. All the results I've found base "finding the bitrate" off of already existing video. I'm talking about LIVE streaming. (indeterminate length) So, I know some basic parts of it, but I just need to know if I'm right or missing anything. For Kbps: Resolution * Framerate / 1024 Is it really that simple? Audio would be a separate element for our purposes here. Am I missing anything from this formula? (Coming up with a proposal of what amount of bandwidth would be required, relative to possible resolution options, so I just need to be sure that I'm not missing anything or inaccurate about it)

• Multiple user database design

  - by dieguitoweb

  I have to develop a basic social network for an academic purpose; but I need some tips for the users management.. The users are subdivided into 3 groups with different privilege: admins,analysts and standards users. For every user should be stored into the database the following information: name,lastname,e-mail,age,password. I'm not quite sure how I should design the database between theese two solutions: 1)one table called 'users' with the 'role' attribute that explain what a user can do and what can't do, and the permissions are managed via php 2)every application user is a database user created with the query 'CREATE ROLE' (It's a postgres database) and he has permissions on some tables granted with the 'GRANT' statement You should take into account that the project is for a database exam.. thanks

• Is vbscripting that difficult?

  - by eric young

  I need to write some vbscripts in my new project. I was told by other people that vbscripting is easy, but seems to me, it is not. For example, in the following example (provided by microsoft), these functions: CreateObject, CreateShortcut, as well as these property names: TargetPath, WindowStyle, Hotkey, etc, are used, but I just cannot find the corresponding API documentation about how to use them. In other words, how do you know you need to call these functions in your vbscripts? Visual Studio 2008/2010 do not have templates for vbscript either. Could anybody tell me what I am missing, and what the best way is to do vbscripting? set WshShell = WScript.CreateObject("WScript.Shell") strDesktop = WshShell.SpecialFolders("Desktop") set oShellLink = WshShell.CreateShortcut(strDesktop _ & "\MyExcel.lnk") oShellLink.TargetPath = _ "C:\Program Files\Microsoft Office\OFFICE11\EXCEL.EXE" oShellLink.WindowStyle = 1 oShellLink.Hotkey = "CTRL+SHIFT+F" oShellLink.IconLocation = _ "C:\Program Files\Microsoft Office\OFFICE11\EXCEL.EXE, 0" oShellLink.Description = "My Excel Shortcut" oShellLink.WorkingDirectory = strDesktop oShellLink.Save

• Threading Problems in ActionScript 2.0?

  - by yar

  Is it possible to have concurrency problems (thread competition) in an onEnterFrame method in ActionScript 2.0? I have written this cheesy code as a guard: if (!busy) { // I suspect some threading problems: is that even possible in flash busy = true; movePanels(); busy = false; } but this is no assurance against thread competition. If so, how can I do a basic semaphore/lock? Note: I suspect threading problems in my app, but if they're impossible, I'll check my code differently.

• which technology is best for a Facebook application Ruby on Rails or C# and ASP?

  - by Johnny

  hi, My friend and I want to write a Facebook application. We've narrowed down the list of possible technologies to Ruby on Rails and C# with ASP. Here are the pros and cons we've thought of. Cons: ASP - proprietary tools like Visual Studio etc. cost (lots of) money. We both don't know ASP (although we're not bad at C#). RoR - It's scripting so might be harder to maintain. My friend doesn't know RoR at all (but he's a fairly proficient programmer so will probably be able to pick it up quickly). Pros: ASP - Facebook has an official SDK for .NET. RoR - I know RoR. It's open source, free and has fast development time. What says the community? Is there something we haven't thought of?

• Find value within a range in lookup table

  - by francis

  I have the simplest problem to implement, but so far I have not been able to get my head around a solution in Python. I have built a table that looks similar to this one: 501 - ASIA 1262 - EUROPE 3389 - LATAM 5409 - US I will test a certain value to see if it falls within these ranges, 389 -> ASIA, 1300 -> LATAM, 5400 -> US. A value greater than 5409 should not return a lookup value. I normally have a one to one match, and would implement a dictionary for the lookup. But in this case I have to consider these ranges, and I am not seeing my way out of the problem. Maybe without providing the whole solution, could you provide some comments that would help me look in the right direction? It is very similar to a vlookup in a spreadsheet. I would describe my Python knowledge as somewhere in between basic to intermediate. Many thanks in advance.

• Activate window/application

  - by LnDCobra

  I have implemented a Splash Screen according to WiredPrairie unmanaged c++ splasher class. But not when my application loads, my window isn't activated. The user has to click on the login box even thought it is the only window open in my application. I have tried the following but none of these work. Topmost = true; Focus(); Activate(); Is there any way to give my login window focus when the application starts? Sometimes the window behind it has focus! (Visual Studio if run on my machine), Explorer or a different application window on other peoples machines. Anyone have any idea?
