 | Hi Teck, I've encountered this problem you faced before and it is surprisingly easy to fix (unless you have a hard disk that is already failing). You will need your Windows XP CD to do this. 1. Boot from your Windows XP CD. You might need to change the settings … |
| | Hi everyone, I've just installed the latest versions of the aforementioned programs in a bid to get started with PHP (yes, I'm new to it). Here are the specific versions: [LIST] [*]Eclipse 3.3.2 M20080221-1800 [*]PDT 1.0.2.v20080102 (plugin installed via Software Updates) [*]WampServer 2.0 (March 7 2008) [*]ZendDebugger for PHP 5.2.x, … |
| | Hey lsu420luv, I would suggest the following way of implementing this part of your project. You would have to implement the output file logic yourself. [CODE]typedef std::map<int, float> Ratings; // Use this type to store judge ratings typedef std::vector<PianoStudent> Players; // Use this type to store PianoStudents struct PianoStudent { … |
| | Re: plz i need help Well, I guess it's because we can't just give you a full solution without you even trying to work something out. Otherwise you wouldn't learn anything would you? However, out of good will I've written sample code for this bracket balancing algorithm without the use of a stack class. You … |
| | Re: Runtime Dear Richard, that's an interesting problem I've never encountered. Please give me some time to check it out. In the meantime, could you please state your system specs (Windows or Linux), your PATH environmental variable, JDK release version (jdk1.5.0_x), and perhaps a code snippet of where the problem originated from.  |
| | Re: C language Erm, you can only set the font size and font whatever if you save the file in a format that provides some extension on formatting, say, like Rich-Text Format (RTF), Hypertext Markup Language (HTML and/or XHTML), Microsoft Word Document, or Portable Document Format (PDF). In other words, you will have …  |
| | Dear moderators, I would like to report a potential bug as in this post: http://www.daniweb.com/techtalkforums/post200331-1.html I used `if (!(fin >> pianoPlayer[i]))` in line 6 and the `[i]` was interpreted as the italic BBCode. This would not have happened if I did not use a close italic BBCode in this line … |
| | I believe Access does not have the [INLINECODE]LIMIT[/INLINECODE] keyword, and that is only an extension specific to MySQL. MS SQL Server uses [INLINECODE]TOP[/INLINECODE] but I don't think Access has this function. Also, Access and MS SQL Server uses square brackets ([INLINECODE][][/INLINECODE]) to delimit its variable names, while MySQL uses the …  |
| | I would suggest that you call the super implementation of [INLINECODE]new[/INLINECODE] and [INLINECODE]delete[/INLINECODE], if that's possible. You must know that these operators are not mere [INLINECODE]malloc[/INLINECODE]'s and [INLINECODE]free[/INLINECODE]'s. Apart from Googling the source for these operators, you can run the debugger in your IDE and step into the code where … |
| | Dear Sul, I do not know if you know about Queries in Microsoft Access. Queries in Microsoft Access are more commonly known as "Views" in the database world. They behave exactly like Tables but some DML may be restricted depending on the complexity of its design. I suggest you create … |
| | You need to buy VB in the sense that you need to buy the IDE/compiler, because VB is Microsoft propietry. But I believe Microsoft provides a free version of the IDE/compiler; I do not know about VB but for VB.NET (they are not the same), you can try [URL=http://msdn.microsoft.com/vstudio/express/vb/]Visual Basic … |
| | I assume this is a directed graph because the file states two opposite edges for any two nodes. You do something along this line: [CODE]ifstream fin("myfile.txt"); if (!fin) cout << "Error" << endl; char buf[81]; while (fin) { if (!fin.get(buf, 81)) break; if (strlen(buf) == 0) // Make sure we … |
 | Hey Tigerdude, I had read through your Floyd-Warshall implementation and I've noticed several things: [list=1] [*]Did you make sure that your constant [INLINECODE]INFINITY[/INLINECODE] did not coincide with any of your edge values in your graph? [*]Are you sure that your graphs do not contain any negative cycles? [*]Look at the … |
| | Dear DashM, correct me if I'm wrong; but since you are (supposedly) enlarging your [INLINECODE]BitMap[/INLINECODE] with a given [INLINECODE]horiz[/INLINECODE] and [INLINECODE]vert[/INLINECODE], shouldn't your temporary array be sized according to that array? In fact, shouldn't you be using [INLINECODE]new[/INLINECODE] or [INLINECODE]malloc[/INLINECODE] to create that array? You are trying to dynamically create … |
 | This is the site: [url]http://java.sun.com/j2se/1.5.0/download.jsp[/url] If you intend to develop applications in Java, download the JDK or the Java Development Kit. Otherwise, download the JRE (not J2EE), which will allow you to only run Java applications. The JDK is a superset of the JRE so you do not need to … |
| | You could use reflection (i.e. get the classes at run-time rather than at compile-time). This is safer because com.sun packages may exist on one OS distribution of Java and not another. Anywho, why do you need to import those classes? If you'd like to use that look-and-feel theme, all you … |
| | Hi cazaletm, I know that starting out with Java I/O can be a little challenging and I see that you've tried all you can. I will not write the whole program out that satisfies all the requirements, but I'll give you a snippet on how to deal with your File … |

| | Writing to a file is pretty simple with Java. Here's some sample code: [CODE]import java.io.*; public class DoSomeFileOutput {[INDENT]public static void main (String[] args) {[INDENT]try {[INDENT]FileWriter fw = new FileWriter("myfile.txt"); PrintWriter pw = new PrintWriter(fw); pw.println("Hello World!"); pw.close();[/INDENT]} catch (IOException ioe) {[INDENT]ioe.printStackTrace();[/INDENT]}[/INDENT]}[/INDENT]}[/CODE] What basically happens is that I wrapped a … |
The End.
