  • howto use JFormattedTextField allowing only letters and numbers

    - by Erik
    I have this code and cannot get MaskFormatter right maskformatter MaskFormatter formatter = null; try { formatter = new MaskFormatter("HHHHHHH"); } catch (ParseException e) { e.printStackTrace(); } txtTroll = new JFormattedTextField(formatter); I need Any hex character (0-9, a-f or A-F) and the "H" should give me only (0-9, a-f or A-F) but im getting it wrong. When i type text only capital letters are typed and it's slow to and when i click away from the txtTroll all letters vanish

  • Best way to implement a Parsing/Editable Richtextbox in WPF

    - by lozzar
    I'm trying to implement (as a prototype initially), a richtextbox control which can be parsed in real time to apply certain formatting options to it. This is being done in WPF so I thought the best way to go about it would be to extend the existing rich text box control. I've run into the issue where it isn't documented well and the examples are quite slow (the ones I found have parse the whole document on every keystroke). The way I've currently decided to go about it is to create a custom Inline element which can hold the formatting tags, and the contents. Hence I only have to parse the current paragraph and the runs in that paragraph for formatting tags. Is there a better way to achieve this? Note this isn't for code/syntax based documents (so AvalonEdit isn't appropriate). Cheers

  • Visual studio not detecting that exe is out of date after perforce revert

    - by CHaskell2
    This is a bit of an odd situation. Here's what's happening. So, we have a VS2008 project which outputs to a number of files under perforce control. These files have the always writable flag set. I compile the project in VS, which gives me up to date binaries on my machine. If I then revert those binaries via perforce, I have the version of the binaries that were up on perforce (ie, old ones.) Despite this, compiling the project again at this point detects no changes and will not remake those binaries. In a way, this makes sense, since none of the code or obj files have changed, but it's not really what I want to happen. This comes up in an edge case on our automated build server. I can think of tons of different little hacks I could do to fix this, but I'm thinking I could be missing something fundamental here. The actual build process uses the Unreal build tool, so there is a bit of magic going on behind the scenes that I'm not entirely familiar with too. Edit: This is a C/C++ project, forgot to mention that.

  • Help finding a USB Joystick mouse?

    - by shane87
    I am currently developing a final year project which involves using a joystick instead of the mouse for those who are physically impaired. Does anyone know where I can find a USB Joystick mouse? All I can find on e-bay and amazon is very sophisticated flight joysticks with loads of buttons and controls etc. I am looking for a plain and simple joystick? If anyone could point me in the right direction I would be very grateful.

  • A jscript variable in a Query

    - by lerac
    Maybe a very simple question. How can I put in this code <Query> <Where> <Eq> <FieldRef Name="Judge_x0020_1" /> <Value Type="Text">mr. R. Sanches</Value> </Eq> </Where> </script> </Query> A variable from jscript in the area of the code where mr. R. Sanches is written. So my jScript contains a dynamic text variable I want to replace mr. R. Sanches with. See where it says THE JAVESCRIPT VAR underneath here: <Query> <Where> <Eq> <FieldRef Name="Judge_x0020_1" /> <Value Type="Text">THE JAVASCRIPT VAR</Value> </Eq> </Where> </script> </Query>

  • Should We Mask Passwords?

    - by Abi Noda
    From Jacob Nielson's "Stop Password Masking": Usability suffers when users type in passwords and the only feedback they get is a row of bullets. Typically, masking passwords doesn't even increase security, but it does cost you business due to login failures. What do you guys think?

  • Autocorrelation returns random results with mic input (using a high pass filter)

    - by Niall
    Hello, Sorry to ask a similar question to the one i asked before (FFT Problem (Returns random results)), but i've looked up pitch detection and autocorrelation and have found some code for pitch detection using autocorrelation. Im trying to do pitch detection of a users singing. Problem is, it keeps returning random results. I've got some code from http://code.google.com/p/yaalp/ which i've converted to C++ and modified (below). My sample rate is 2048, and data size is 1024. I'm detecting pitch of both a sine wave and mic input. The frequency of the sine wave is 726.0, and its detecting it to be 722.950820 (which im ok with), but its detecting the pitch of the mic as a random number from around 100 to around 1050. I'm now using a High pass filter to remove the DC offset, but it's not working. Am i doing it right, and if so, what else can i do to fix it? Any help would be greatly appreciated! double* doHighPassFilter(short *buffer) { // Do FFT: int bufferLength = 1024; float *real = malloc(bufferLength*sizeof(float)); float *real2 = malloc(bufferLength*sizeof(float)); for(int x=0;x<bufferLength;x++) { real[x] = buffer[x]; } fft(real, bufferLength); for(int x=0;x<bufferLength;x+=2) { real2[x] = real[x]; } for (int i=0; i < 30; i++) //Set freqs lower than 30hz to zero to attenuate the low frequencies real2[i] = 0; // Do inverse FFT: inversefft(real2,bufferLength); double* real3 = (double*)real2; return real3; } double DetectPitch(short* data) { int sampleRate = 2048; //Create sine wave double *buffer = malloc(1024*sizeof(short)); double amplitude = 0.25 * 32768; //0.25 * max length of short double frequency = 726.0; for (int n = 0; n < 1024; n++) { buffer[n] = (short)(amplitude * sin((2 * 3.14159265 * n * frequency) / sampleRate)); } doHighPassFilter(data); printf("Pitch from sine wave: %f\n",detectPitchCalculation(buffer, 50.0, 1000.0, 1, 1)); printf("Pitch from mic: %f\n",detectPitchCalculation(data, 50.0, 1000.0, 1, 1)); return 0; } // These work by shifting the signal until it seems to correlate with itself. // In other words if the signal looks very similar to (signal shifted 200 data) than the fundamental period is probably 200 data // Note that the algorithm only works well when there's only one prominent fundamental. // This could be optimized by looking at the rate of change to determine a maximum without testing all periods. double detectPitchCalculation(double* data, double minHz, double maxHz, int nCandidates, int nResolution) { //-------------------------1-------------------------// // note that higher frequency means lower period int nLowPeriodInSamples = hzToPeriodInSamples(maxHz, 2048); int nHiPeriodInSamples = hzToPeriodInSamples(minHz, 2048); if (nHiPeriodInSamples <= nLowPeriodInSamples) printf("Bad range for pitch detection."); if (1024 < nHiPeriodInSamples) printf("Not enough data."); double *results = new double[nHiPeriodInSamples - nLowPeriodInSamples]; //-------------------------2-------------------------// for (int period = nLowPeriodInSamples; period < nHiPeriodInSamples; period += nResolution) { double sum = 0; // for each sample, find correlation.

Edit: Changed the code to implement a high pass filter with a cutoff of 30hz (from What Are High-Pass and Low-Pass Filters?, can anyone tell me how to convert the low-pass filter using convolution to a high-pass one?) but it's still returning random results. Plugging it into a VST host and using VST plugins to compare spectrums isn't an option to me unfortunately.

  • Making one of a group of similar form fields required in CakePHP

    - by Pickledegg
    I have a bunch of name/email fields in my form like this: data[Friend][0][name] data[Friend][1][name] data[Friend][2][name] etc. and data[Friend][0][email] data[Friend][1][email] data[Friend][2][email] etc. I have a custom validation rule on each one that checks to see if the corresponding field is filled in. Ie. if data[Friend][2][name] then data[Friend][2][email] MUST be filled in. FYI, heres what one of the two rules look like: My form validation rule: ( I have an email validation too but that's irrelevant here) 'name' => array( 'checkEmail' => array( 'rule' => 'hasEmail', 'message' => 'You must fill in the name field', 'last' => true ) ) My custom rule code: function hasEmail($data){ $name = array_values($data); $name = $name[0]; if(strlen($name) == 0){ return empty($this->data['Friend']['email']); } return true; } I need to make it so that one of the pairs should be filled in as a minimum. It can be any as long as the indexes correspond. I can't figure a way, as if I set the form rule to be required or allowEmpty false, it fails on ALL empty fields. How can I check for the existence of 1 pair and if present, carry on? Also, I need to strip out all of the remaining empty [Friend] fields, so my saveAll() doesn't save a load of empty rows, but I think I can handle that part using extract in my controller. The main problem is this validation. Thanks.

  • What's the best way to read/write array contents from/to binary files in C#?

    - by Eric
    I would like to read and write the contents of large ( 2GB), raw volume files (e.g. MRI scans). These files are just a sequence of e.g. 32 x 32 x 32 floats so they map well to 1D arrays. I would like to be able to read the contents of the binary volume files into 1D arrays of e.g. float or ushort (depending on the data type of the binary files) and similarly export the arrays back out to the raw volume files. What's the best way to do this with C#? Read/Write them 1 element at a time with BinaryReader/BinaryWriter? Read them piece-wise into byte arrays with FileStream.Read and then do a System.Buffer.BlockCopy between arrays (keeping in mind that I want 2GB arrays)? Write my own Reader/Writer?

  • Pipe data from InputStream to OutputStream in Java

    - by Wangnick
    Dear all, I'd like to send a file contained in a ZIP archive unzipped to an external program for further decoding and to read the result back into Java. ZipInputStream zis = new ZipInputStream(new FileInputStream(ZIPPATH)); Process decoder = new ProcessBuilder(DECODER).start(); ??? BufferedReader br = new BufferedReader(new InputStreamReader( decoder.getInputStream(),"us-ascii")); for (String line = br.readLine(); line!=null; line = br.readLine()) { ... } What do I need to put into ??? to pipe the zis content to the decoder.getOutputStream()? I guess a dedicated thread is needed, as the decoder process might block when its output is not consumed.

  • Understanding byte order and functions like CFSwapInt32HostToBig

    - by Typeoneerror
    I've got an enumeration in my game. A simple string message with an appended PacketType is being sent with the message (so it knows what to do with the message) over GameKit WIFI connection. I used Apple's GKRocket sample code as a starting point. The code itself is working fantastically; I just want to understand what the line with CFSwapInt32HostToBig is doing. What on earth does that do? and why does it need to do it? My guess is that it's making sure the PacketType value can be converted to an unsigned integer so it can send it reliably, but that doesn't sound all that correct to me. The documentation states "Converts a 32-bit integer from big-endian format to the host’s native byte order." but I don't understand what the means really. typedef enum { PacketTypeStart, // packet to notify games to start PacketTypeRequestSetup, // server wants client info PacketTypeSetup, // send client info to server PacketTypeSetupComplete, // round trip made for completion PacketTypeTurn, // packet to notify game that a turn is up PacketTypeRoll, // packet to send roll to players PacketTypeEnd // packet to end game } PacketType; // .... - (void)sendPacket:(NSData *)data ofType:(PacketType)type { NSLog(@"sendPacket:ofType(%d)", type); // create the data with enough space for a uint NSMutableData *newPacket = [NSMutableData dataWithCapacity:([data length]+sizeof(uint32_t))]; // Data is prefixed with the PacketType so the peer knows what to do with it. uint32_t swappedType = CFSwapInt32HostToBig((uint32_t)type); // add uint to data [newPacket appendBytes:&swappedType length:sizeof(uint32_t)]; // add the rest of the data [newPacket appendData:data]; // Send data checking for success or failure NSError *error; BOOL didSend = [_gkSession sendDataToAllPeers:newPacket withDataMode:GKSendDataReliable error:&error]; if (!didSend) { NSLog(@"error in sendDataToPeers: %@", [error localizedDescription]); } }

  • Asp.Net MVC 2 Client validation implementation for Enterprise Library Validation Block

    - by er-v
    Hello to everybody. I've found a very good article about how to use EntLib Validation Block for server validation in MVC 2. But as there pointed out The current design of EntLib’s Validation Application Block uses the Composite pattern; that is, when we ask for validation for an object, it returns back a single validator object that contains a list of all the validation work to be done. While this is very convenient from a normal usage scenario, the unfortunate side-effect is that we can’t “peek inside” to see what the individual validations are that it’s doing, and therefore can’t generate the appropriate client-side validation hints. So how is it possible to implement client side validation for EntLib? Is there work around?

  • Alerting for incorrect cell values

    - by Allan
    My problem: I have two ranges R16 and R01. These ranges were set up by swiping each range and then renaming them in the upper left panel of the sheet. Each range requires users to fill in each cell with a value. R16 requires users to enter a number of 0 through 5. The range R01 requires a value of 0 or 1 to be entered. NO cell can be left blank in any cell within these two ranges. These ranges and requirements are specific to this sheet only. It would be nice if at the time of user entering a number, an error message appeared like [invalid entry] if the value inputted was outside parameters set. For example, in R16, if someone entered 12 or -1 they would be alerted. Finally when the user presses a button on the page to use these values in a separate process, it is essential to check that no cell is left blank. I am trying to find a way to halt the running of the marco (via the button) if these parameters above are not met. Thank you

  • Finding the order of method calls in Eclipse

    - by Chathuranga Chandrasekara
    Suppose I have a big program that consists of hundreds of methods in it. And according to the nature of input the program flow is getting changed. Think I want to make a change to the original flow. And it is big hassle to find call hierarchy/ references and understand the flow. Do I have any solution for this within Eclipse? Or a plugin? As an example, I just need a Log of method names that is in order of time. Then I don't need to worry about the methods that are not relevant with my "given input" Update : Using debug mode in eclipse or adding print messages are not feasible. The program is sooooo big. :)

  • Can ASM method-visitors be used with interfaces?

    - by Olaf Mertens
    I need to write a tool that lists the classes that call methods of specified interfaces. It will be used as part of the build process of a large java application consisting of many modules. The goal is to automatically document the dependencies between certain java modules. I found several tools for dependency analysis, but they don't work on the method level, just for packages or jars. Finally I found ASM, that seems to do what I need. The following code prints the method dependencies of all class files in a given directory: import java.io.*; import java.util.*; import org.objectweb.asm.ClassReader; public class Test { public static void main(String[] args) throws Exception { File dir = new File(args[0]); List<File> classFiles = new LinkedList<File>(); findClassFiles(classFiles, dir); for (File classFile : classFiles) { InputStream input = new FileInputStream(classFile); new ClassReader(input).accept(new MyClassVisitor(), 0); input.close(); } } private static void findClassFiles(List<File> list, File dir) { for (File file : dir.listFiles()) { if (file.isDirectory()) { findClassFiles(list, file); } else if (file.getName().endsWith(".class")) { list.add(file); } } } } import org.objectweb.asm.MethodVisitor; import org.objectweb.asm.commons.EmptyVisitor; public class MyClassVisitor extends EmptyVisitor { private String className; @Override public void visit(int version, int access, String name, String signature, String superName, String[] interfaces) { this.className = name; } @Override public MethodVisitor visitMethod(int access, String name, String desc, String signature, String[] exceptions) { System.out.println(className + "." + name); return new MyMethodVisitor(); } } import org.objectweb.asm.commons.EmptyVisitor; public class MyMethodVisitor extends EmptyVisitor { @Override public void visitMethodInsn(int opcode, String owner, String name, String desc) { String key = owner + "." + name; System.out.println(" " + key); } } The Problem: The code works for regular classes only! If the class file contains an interface, visitMethod is called, but not visitMethodInsn. I don't get any info about the callers of interface methods. Any ideas?

  • How to safely let users submit custom themes/plugins for a Rails app

    - by Brian Armstrong
    In my rails app I'd like to let users submit custom "themes" to display data in various ways. I think they can get the data in the view using API calls and I can create an authentication mechanism for this. Also an authenticated API to save data. So this is probably safe. But i'm struggling with the best way to let users upload/submit their own code for the theme. I want this to work sort of like Wordpress themes/plugins where people can upload the thing. But there are some security risks. For example, if I take the uploaded "theme" a user submits and put it in it's own directory somewhere inside the rails app, what are the risks of this? If the user inserts any rails executable code in their theme, even though it's the view they have full access at that point to all the models, everyone's data, etc. Even from other users. So that is not good. I need some way to let the uploaded themes exist in a sandbox of the rails app, but I haven't seen a good way to do this. Any ideas?
