 | I'd like to help... but I have no knowledge of magic squares or the mentioned algorithm... or perhaps I do and it just sounds foreign. Care to explain what a magic square is? An example would suffice. It appears that you just need a bunch of criteria to verify if …  |
| | Hi, I'm trying to gain access to a postGres database. I've tried to use Npgsql but I get an error with the Mono.Security.dll file (the version is incorrect > but I can't find v2). So I thought I'd give the above method a try. I was just wondering in the …  |
| | I'm creating a custom `ComboBox` that allows the user to select a date; the calendar display is localized making the built-in `DateTimePicker` undesirable (see [here](http://support.microsoft.com/Default.aspx?scid=kb;en-us;889834&x=18&y=19) for more information). I need the UI control to mirror the look and feel or the existing components. Here's what I've tried and the problems … |
| | Greetings :) I'm trying to intercept some Win32 messages; in particular I want to respond to a [icode]TVN_GETDISPINFO[/icode] notification. This notification is sent in the form of a [icode]WM_NOTIFY [/icode](see [URL="http://msdn.microsoft.com/en-us/library/bb773518(v=vs.85).aspx"]here[/URL]) and contains a pointer to [icode]NMTVDISPINFO [/icode]which gives access to a [icode]TVITEM[/icode]. [icode]TVITEM [/icode]has a [icode]LPTSTR pszText[/icode] field that … |
| | You can think of a [B]static [/B]method as a [B]class [/B]method; methods must be contained within a [B]class [/B]in C#. The following should work: [CODE]if (MyClass.IsPostponed()) { .. }[/CODE] Where [I]MyClass [/I]contains the definition of the [B]static [/B]method. |
| | Good day :) I'd like to be able to change the [I]Region and Language[/I] options of [I]Windows 7[/I] from a C# program. Changing this setting manually requires a system restart so I imagine if this is possible at the programming level, the system would also have the restart? Any thoughts? … |
| | Good day :) I'm trying to display some Unicode text (Выход) on a Button. C# uses UTF-16 encoding but I'm reading my data from a UTF-8 encoded file so I take the necessary steps to ensure that I've read the data correctly. In debug mode I see that the string … |
| | It appears that you're having problems creating a class hey? So I'm going to give you and example and clear up some of the termonolgy. Consider: [code]class A { private String name; public A() { name = "Test"; } public void setName(String n) { name = n; } public String …  |
| | I agree with Masijade, and I think you could probably just change the [I]JFrame[/I] inheritance to [I]JPanel[/I], well depending on your actual coding hehe Anyway, what I wanted to recommend is NetBeans. It’s a very innovate IDE when one is dealing with GUI applications :icon_cool: You’d just create a new … |
| | Greetings! I have a win32 native dll (perhaps that's not the correct term - it's basically a C compiled dll) that I'm accessing in C#. The method signature of the C code (not the actual signature in the dll): [code=C++] char* TestMethod() [/code] I'd like to access the [B]char*[/B] as …  |
| | Greetings! I have a C# dll generated from a .resx file (I believe it's called a satellite dll). This stores simple key to string mappings (used for language localization). I was wondering if it's possible and feasible to access the information stored in the C# dll from a C++ unmanaged … |
| | Hi there, I'm trying to access a resource only dll (compiled with the [i]/NOENTRY[/i] linker option) within C#. The dll file was created using a rc file that contains a [b]STRINGTABLE[/b]. I used [b]CComBSTR[/b] to load the string resource from the dll in C++; I'm not sure how to do …  |
| | Hey guys, I was wondering: suppose I created a standard console application and but I now want to make the program (well the code behind the program) into a dll file or some other reference object that can be added to other projects - how would this be done? I'm … |
| | I agree with Masijade, one would tend to not create an 'exe' file from a Java program. Indeed there should exist a byte code to exe compiler, though I wonder how efficient/valid one would be; Java is a growing language and some of the specifications of Java aren't easily portable … |
 | sabithpocker, so that's how you'd access an image? I agree that the image can be included in the generated [I]jar[/I] file. However, my feeling is that the file will not be accessible via the Java code since the current path (using relative addressing) would be the path the [I]jar[/I] executable …  |
| | The whole point of declaring something private (which as it was explained means that it is only accessible within the scope of that class) is to prevent the value of the variable changing without supervision. In your case perhaps we would want the number of jackets to lie between 0 … |
| | I'm a bit perplexed... since this topic is in the Java forum I'm assuming that some Java programming is involved. As such, I'm imagining a Java Applet since we're speaking about something that's web based. Please correct me if I'm wrong, but if the server knows both users that belong … |
| | I'm not sure why you said 'no,' [I]sillyboy[/I]? But yes, since chicago1985 instantiated the object to [B]null[/B], there wouldn't be anything to 'get.' What concerns me is that he actually declared the variable [B]request[/B]. I'm assuming the class this method belongs to, is a [U]servlet[/U]? That is, the class extends … |
| | Please marked this post as solved, thank you. |
| | Re: Palindromes Hi there, I'm not entirely sure why you're running that [I]for[/I] loop that contains the undeclared variable. Remember that the end of line terminator is not returned by the [B]readLine()[/B] method of [B]BufferedReader[/B]. Also, if you just want to get rid of leading/following whitespaces (like a space) then you can … |
| | So my first question would be: what are you comparing? I only see that you've implemented the [I]Selection Sort[/I]... are you wanting to compare different methods of carrying out the [I]selection sort[/I]? Next, your criteria for comparison isn't clear. Runtime seems like the best criteria and would require that you … |
| | Re: Image Path Read this thread: [URL="http://www.daniweb.com/forums/thread42410.html"]http://www.daniweb.com/forums/thread42410.html[/URL] You'll find that there are multiple ways to do what you need. I suggested [I]getResource()[/I]. |
| | I agree with stephen84s, you need some sort of overall view of how the different parts of your system pull together. Generally if you have an applet, it would probably have to communicate with a server that would fulfil requests such as user authentication. It would communicate with the server … |
| | lol that was funny! The [I]Timer[/I] class is definitely the way to go. And since the Timer class uses [I]ActionEvent[/I]s, the way the count down is displayed is controlled by you (that is, the [I]ActionEvent[/I] can be to simply [U]repaint()[/U] the updated time). Hmmm, and what if you wanted an …  |
| | Interesting... I haven't actually dealt with applet windows before but there is a method [COLOR="Green"][I]setResizable()[/I][/COLOR] that belongs to the [B]Frame[/B] class. I believe this method will prevent the user from resizing the window thus disallowing the maximize option. So if you could tell me how you create the applet window … |
 | While there isn't a stringent specification for these files, I doubt Microsoft Excel will allow such character encodings. So I tested it out... I copied one of the characters you gave as an example and pasted in Excel - it showed. I then saved the file as CSV (Excel gave … |
| | Hi guys, I'm a MSc student and my research topic involves developing a Sensor Web application that predicts the spread of wildfire in South Africa. Part of that research involves creating a wind movement simulation using computational fluid dynamics. I don't have any engineering background and have only begun exploring … |
| | You make use of certain classes that aren't part of the standard Java API so I'm unable to really follow the code you've given. I did notice that you create a [I]Pixel[/I] array in method [I]decryptPicture()[/I] and then you begin to populate the array depending on a Boolean evaluation. Since … |
| | I'm a little confused and that's probably because I'm not sure what a dynamic row is? I looked at your attachments which are quite long when opened... I noticed you're using JavaScript. Is there a problem with using Java embedded code? The way that I've been taught to retrieve data … |
| | Hi there, well your approach is actually one of the best ways to pass data between classes. One usually does this via the class constructor just as you have in the parking ticket class. The class that handles the parking tickets would require both objects to achieve its goal. What … |
