  • I would like to learn C++, what is the first step ?

    - by Cesar
    My actual experience comes from PHP and Delphi(Borland) and recently also from Obj-C (iPhone sdk). In the past I also used Java, Python, VB 6 and some other scripting language. I would like to learn C++ because i need a standard tool for write compiled applications with good performance but i have no idea about witch environment i have to choose (Ex: Borland, Microsoft, Eclipse+MinGW, ...). Based those parameters: Most useful more opensource project or work requests Most standard not a proprietary versions Biggest community documentation, manuals, tutorials, forums... Better IDE add-ons, highlight, debug, cross platform, autocomplete... Easy setup A simple setup, to focus on learning the basics Actually I'm on OSX but I can use a VM if needed. Advices about tutorial or books are welcome. I hope it's not too generic as question.

  • How to add characters to reach the maximum size of a char[].

    - by Bon_chan
    Hi folks, I have the following part of code : for(int i=0;i<n;i++) { printf("Student %d\n",i+1); printf("Enter name : "); scanf("%s",&(student+i)->name); fflush(stdin); lengthName = strlen((student+i)->name); while(lengthName !='\0') { }} when the length is shorter than 10, it will add hyphens until reaching the maximum size. Ex : John = 6 hyphens will be added I know how to do it in csharp but can't figure it out in c. Could some of you give me some lights please? PS : Oh yes the variable name is char name[10+1] and it a part of the structure called student.

  • IE7 and IE8: Float clearing without adding empty elements

    - by tk-421
    Hello, I'm having a problem similar to the one described here (without a resolution): http://stackoverflow.com/questions/2467745/ie7-float-and-clear-on-the-same-element The following HTML renders as intended in Firefox but not in (both) IE7 and IE8: <html> <head> <style> ul { list-style-type: none; } li { clear: both; padding: 5px; } .left { clear: left; float: left; } .middle { clear: none; float: left; } .right { clear: right; float: left; } </style> </head> <body> <ul> <li>1</li> <li class="left">2</li> <li class="right">3</li> <li class="left">4</li> <li class="middle">5</li> <li class="right">6</li> <li>7</li> </ul> </body> </html> This is a form layout, and in Firefox the results appear like: 1 2 3 4 5 6 7 That's what I'm going for. In IE7 and IE8 however, the results are: 1 2 3 5 6 4 7 [Note: I don't want to float anything to the right because I want the fields on my form to left-align correctly, without a giant space in-between the floated fields to account for the parent container's width.] Apparently I need a full clear, and can probably add an empty list-item element to the list to force clearing, but that seems like a dumb solution and sort of defeats the purpose. Any ideas? I've spent a few hours reading and trying different options without success.

  • Microsoft Visual Studio License

    - by Germstorm
    I developed a small winforms application for myself in Microsoft Visual Studio 2008 Professional Edition at my workplace, the Visual Studio is licensed to the firm I work at. If I want to sell that application, what are my license options? EDIT: The issue here is not my relationship with my employer (the code was written after hours, we have an understanding) but my relationship with Microsoft. Ex. if I continue developing in Visual Studio Express can I keep my old code? Is there a way to verify if some assemblies were written using a Visual Studio Professional?

  • Calling ASP.NET web service function via GET method with jQuery

    - by the_V
    Hi, I'm trying to call web service function via GET method using jQuery, but having a problem. This is a web service code: [WebService(Namespace = "http://something.com/samples")] [ScriptService] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] public class TestWebService : System.Web.Services.WebService { [WebMethod] public string Test2() { string result = null; try { result = "{'result':'success', 'datetime':'" + DateTime.Now.ToString() + "'"; } catch (Exception ex) { result = "Something wrong happened"; } return result; } } That's the way I call the function: $.ajax({ type: "GET", url: "http://localhost/testwebsite/TestWebService.asmx/Test2", data: "{}", contentType: "application/json", dataType: "json", error: function (xhr, status, error) { alert(xhr.responseText); }, success: function (msg) { alert('Call was successful!'); } }); Method is called successfully, but result string gets covered by XML tags, like this: <string> {'result':'success', 'datetime':'4/26/2010 12:11:18 PM' </string> And I get an error because of this (error handler is called). Does anybody know what can be done about this?

  • is DISPID_VALUE reliable for invokes on IDispatchs from scripts?

    - by Georg Fritzsche
    Continuing from this question, i am confused whether DISPID_VALUE on IDispatch::Invoke() for script functions and properties (JavaScript in my case) can be considered standard and reliable for invoking the actual function that is represented by the IDispatch? If yes, is that mentioned anywhere in MSDN? Please note that the question is about if that behaviour can be expected, not what some interfaces i can't know in advance might look like. A simple use case would be: // usage in JavaScript myObject.attachEvent("TestEvent", function() { alert("rhubarb"); }); // handler in ActiveX, MyObject::attachEvent(), C++ incomingDispatch->Invoke(DISPID_VALUE, IID_NULL, LOCALE_SYSTEM_DEFAULT, DISPATCH_METHOD, par, res, ex, err); edit: tried to clarify the question.

  • Extend Javascript Date Object

    - by jAndy
    Hi Folks, I'm curious what would be the best practice to extend the Date constructor. The problem I'm facing is, that the Internet Explorer (< 7+8) can't parse a date like new Date('2010-05-11'); I have to admit that this is not a standard method to parse, anyways FireFox and Chrome perform well on that kind of date string. Now I'm wondering, should I just split/parse/rebuild the string before calling new Date() or is there a more elegant solution ?

  • Android: how to update UI dynamically?

    - by pandre
    I have an Android app and I need to change UI dynamically: ex: when user presses a button, I want to change the current activity's views and, as in some cases there are a lot of views involved, I need to display a ProgressDialog. I have been using an AsyncTask, but I think that it is not the best solution, because AsyncTask's doInBackground runs a different thread, so I can't update UI from there - I have to use runOnUiThread, which runs the code in the UI Thread, but freezes the progress dialog that is shown. I guess there should be more people with similar issues, as updating UI while displaying a ProgressDialog seems to be something done regularly by applications. So does anyone have a solution to this?

  • How can you setup multiple WSGI apps on one server?

    - by Shakakai
    I'm working on a python based server product where a user can install WSGI-based python apps on their server. I can enforce any restriction on the application structure or format to make this easy. The user workflow would be: browse an app market, showing a list of WSGIpython apps select an app and choose "install" the app would be downloaded from a remote server to the user's server the http server would then have to be configured to start serving that application from the app's id, ex. a blog app with an id of "blog" at "/blog/", so all requests below /blog/ would be seen as root by the blog application. Any suggestions on how to set something like this up? Holler if my flow of consciousness lost you ;)

  • is there a way to show what field you updated in mysql?

    - by ggfan
    When users edit their account, I want to display a confirmation page that shows their updated information with the fields that they changed in bold. Is there a mysql statement that allows you to select the fields that a user changes? If not, how exactly can I achieve this Ex: (editaccount.php) first_name: bob last_name: builder email: [email protected] When they change say their first name to "james", the confirmation page shows their first name in bold because they changed that but the other areas are still normal text. first_name: <b>James</b> last_name: builder email: [email protected]
