You have to write code for everything in Java - that's pretty much the point. What you write really depends on what you are trying to do, which you failed to adequately explain. What do you want to "skip blank spaces" in? What are you wanting to do with the "not blank spaces" remainder?

I seriously doubt it, since you didn't bother to post any code or even what language you are writing it in.

Well, now is a good time to learn about them (actually Lists): http://java.sun.com/docs/books/tutorial/collections/index.html

Well, you're headed towards a "0" anyway if you haven't made any further effort on this in 5 days and can't find a single example of graphics in C as a starting point.

No one is going to write it for you.

A recent Federal Circuit court ruling may be the end of software patents in the US. Of course, we'll have to wait to see how the patent lawyers and lobbyists fare in fighting it off.

I suggest that the control panel button is made like the forum buttons, i.e. click on it to go directly to the user control panel, and hover on it to bring up the new menu.

I agree, since that's the link I use more than any other on the site. It's only one more click to get there now, so not really a big deal, but given it's frequency of use it would be nice if it were a direct link like before.

Try calling startTask() before you set the dialog visible.

That is what I was trying to determine as well. It sounds like you are just asking about communicating between 2 classes in the same application, which is no trouble at all. Post a little bit of the code and it would be much clearer what you are trying to do.

It would really help if you posted a little more information about the nature of the two "programs". Separate JVMs? Concurrently executing threads? You question is a little too unclear to give an answer.

You already have the basic part of that in place. Read each line of the file, use split() to separate the elements, then add that pair of values to your series for the chart.

There is a bar chart demo file in the source\org\jfree\chart\demo directory of JFreeChart.

Just drag your screen to the right :)

I don't think you want an XYSeries for that. If you want it to be a line chart (bar chart seems more appropriate to me, but you seem to want the line chart), try this instead

private CategoryDataset createDataset() throws Exception {

    DefaultCategoryDataset dataset = new DefaultCategoryDataset();
    dataset.addValue(255, "Errors", "error1");
    dataset.addValue(34, "Errors", "error2");
    dataset.addValue(111, "Errors", "error5");
    dataset.addValue(23, "Errors", "error3");

    return dataset;
}

private JFreeChart createChart(CategoryDataset dataset) {
    // create the chart...
    JFreeChart chart = ChartFactory.createLineChart(
            "Medida", // chart title
            "Error Code", // x axis label
            "Count", // y axis label
            dataset, // data
            PlotOrientation.VERTICAL,
            true, // include legend
            true, // tooltips
            false // urls
    );

    return chart;
}

All you have to do is build that category dataset with the first and second elements of your spilt() on the text file line.

No of course not. I don't have that file and you have it commented out. You said the graphic was not plotting.

The hate mail section is the best.

Typed pages or hand-written pages?

Nice find. Will keep that handy :)

The graph shows just fine for me.

Take a look at http://www.cokeandcode.com/ for Java game programming tutorials.

The new post listings on the "main page" for top-level forums no longer indicate which forum the post is in. Listing the forum is helpful to determine if the post is in one of the forums you participate in a lot.

Mark the thread as solved if the issue is resolved.

Whether you use arrays, Lists, or whatever, the point is still the same. You'll need to read the file content into some structure and then use JDBC to update/insert your table values.

Ah. I have sigs turned off, so I never see those.

LOL, you are mourning for your country? What country are you from? Here in our country, we are mourning since the dawn of the republic.

Um, what? Is that supposed to make sense?

Anyways, as for streaming, there two sites are good as well:
http://www.pandora.com/ (US only, due to licensing issues)
http://www.last.fm/home

With a cigarette.

Poor Bob. That has to be very deflating to his huge swelling of pride. :(

Congratulations.

Perhaps you should post in the Perl forum. This is the Java forum.

Just open the file in a text editor.

If you have a specific question, ask it. Otherwise, do your own homework.

http://www.exampledepot.com/egs/java.io/WriteToFile.html

Why are you trying to use both a FileWriter and a BufferedWriter against the same file? Just use the BufferedWriter.

Use the newLine() method to write the line separator, instead of appending '\n' to your text.

Also note that directories will also be included and can be discerned with file.isDirectory(). If you need to include file counts from subdirectories, you'll need to do the recursion yourself.

It's all right here: http://java.sun.com/docs/books/tutorial/jdbc/basics/index.html

Drive-by code snippet.

Please have a look into the code.

Why? Is there something wrong with it? If so, what specifically?

Please also explain the function of

e.printstacktrace();

There is no such function as you have written it. There is, however, a printStackTrace() method on Throwable. Read that API link to see what it does.

Sure, this is all you need.

Microsoft may continue to support them for quite awhile, but I think content providers (developers) will drop IE6 more quickly due to the standards-compliance issues.

This is the start of the class - is this going along the right lines? We do not know where to go from here. . .

class LectureTheatre {
    public static void main(String[] arguments) {
		
		private int maxOccupancy;
		private int layoutStyle;
		private String lectureTheatreName;
	
			
		}

		
	}
}

No. Take main() out altogether at this point. It has nothing at all to do with the class itself.

That pretty much sums up all of his posts to date.

The POI project page says they are working on Excel 2007 support, but I'm not sure how far along it is.

I haven't tried JExcel, so I can't really address the differences between them.
