Hi all, I was recently having a look at the pywin32 module and found a multitude of approaches on how to find the color of a pixel given its coordinates, but was wondering if there was a way to find the coordinate of a pixel given its particular color, either as an rgb tuple or hex vlaue. any help is greatly appreciated

A long standing complaint with the standard progress bar control is that there is no easy way to display text. In spite of numerous requests, Microsoft has not included this capability. The following code includes a class, `CustomProgress` which inherits the standard `ProgressBar` and adds such a feature. It is fairly easy to use. If you want to show a percentage progress you set `Text` to a null string and the percentage will be calculated from the `Minimum` and `Maximum` value properties. If you want a custom string then assign it to `Text`. Either the percentge or custom text will …

There are times when you need to make sure your counter starts at an odd or even number. Even is pretty simple - `counter = counter + modulus(counter)`. If counter is even it stays, if it's odd it gets incremented by 1. Odd is a bit more complicated - `counter = counter + modulus(counter + 1)`, If counter is odd it stays, if it's even it gets incremented by 1. if you're in danger of counter being the max value you can always subtract instead. These basic algorithms should work for any language that has a modulus operator/function. I've included …

Hello, I have created a spelling corrector for a project and currently I am struggling on making it work in real-time application (on-the-fly) By this I mean, that I am reading the input of the user (anywhere on the Windows OS - not only in python shell) with the python keyboard library and when the user enters a space I am checking the spelling of the entered word. If it is correct, the program does nothing but if it is wrong the program deletes the wrong word and re-writes the correct one. I have implemented the last functionality of deletion-and-rewrite …

Hi, I am developing an app that monitors and corrects the user input based on some rules. I am reading the events from keyboard with the keyboard python module. I faced some problem when the user types very fast, as regards some overlays of text. By this I mean that when my app writes the correct input, the user continues writing and may writes before the corrector types the whole word. I found, that I can start a keyboard hook with suppressed output to screen and tried to implements a solution. In the above code I tried recreating the problem …

So I got a problem with the settings Tab in VB.Net. The settings are not displaying properly. There is a gap in the middle of the display. ![set.jpg](/attachments/large/4/ce53b8bed890123494c52258313e0760.jpg) The second problem I have is this: VB creates a settings file in the App Data folder: InClass.exe_Url_eoaehkudo2dalqpbmdabua2u0ulhsacj However, If I try to synchronize settings to get rid of the gap, I get the following msg. ![Msg.jpg](/attachments/large/4/615f389896f98f13a1edb3b131bbaca9.jpg) Here I can see that synchronize looks into the correct folder but the file names are different. Any ideas hoe to fix this? Thanks for reading

As part of a project to manage my collection of photos, I wanted to add the capability of displaying a series of files as thumbnails. This posed me with three problems: 1. how to preserve the aspect ratio of the original images 1. how to generate the thumbnails without tying up the application 1. how to avoid running out of memory Because generating thumbnails of images is (I think) of reasonably wide interest I thought I'd write it up as a code snippet. To recreate the project, start with a blank form and add two buttons, btnDetails and btnThumbs. Add …

When working with TCP client sockets I often find myself frustrated with the lack of event-driven support. I usually end up writing a whole bunch of code to determine disconnects, reconnecting, etc and I figuired it's time to just write my own class for this stuff. I figuired I'd share it with all of you. The implementation is quite simple, I'll provide an example below. I have XML commented all the public properties and methods, the rest is up to you to figuire out if you want to make any changes! public partial class Form1 : Form { EventDrivenTCPClient client; …

Hi good people of Danniweb, I've looked at a lot of examples on line and I cannot figure out what is going wrong. My program has to transfer a simple delimited text file from the local machine up to a specified directory on a FTP server. After I have run the routine, I can see the file in the correct directory in the FTP server BUT it is empty i.e. no text. I tried copying the same file to the same directory via windows explorer and it copied up so I don't think there is an issue with rights or …

Hey guys, I would like some help regarding saving or reading to or from a bin file. I've read several online tutorials about file input/output, however it doesn't given specific information when applying it to both an array of structures. My knowledge of pointers is weak, as I constantly need to look over examples to get an idea of whats going on. Heres my attempt: [CODE] #define PLANET_SIZE 10 /* Called from function */ save(planet_t writePlanet[], *totalSize); /* define as int* totalSize */ read(planet_t *writePlanet); typedef struct{ char name[20]; }planet_t; /* Save to file */ void save(planet_t writePlanet[], int totalSize){ …

How do I make a cube in javafx that have 6 different textures on each side of the cube? The only way I know how to solve this, is by making 6 imageviews and give them each a specific coordinates that make them look like a cube. Is there a other way to do this? Like, I like to give the cube later on lighting, and some rotations. It will be more complex if I use this method. Btw, I heard about Triangle Mesh, but I don't know how TextureCoords works. handy links: https://docs.oracle.com/javase/8/javafx/api/javafx/scene/shape/TriangleMesh.html https://docs.oracle.com/javase/8/javafx/api/javafx/scene/shape/Box.html

Hi! It's been a while since I last posted here. I've just gotten started with Windows Service, and have created a sort of 24/7 service to update a database. But because it's my very first project (besides the tutorial one) I feel that I could use some assistance in checking it over. The intent is to have it run a method from a class at about once every 24 hours. If anyone of you clever people could spare a moment to see if I've made mistakes. (Ignore the database connections. Those work) Imports System Imports System.Timers Imports System.Runtime.InteropServices Public Class …

Hi. I want to detect a face and draw line exactly around the face to crop it. I searched a lot and used the EmguCV face detector. but now my code just draw a "rectangle" around the face and if I crop it, I will have a rectangle with a face inside it and it's not useful for me. this is the core of my simple code: CascadeClassifier _cascadeClassifier = new CascadeClassifier(Application.StartupPath + "/haarcascade_frontalface_alt_tree.xml"); using (var firstImage = Image.FromStream(saveImageStream)) { var bgrImage = new Image(new Bitmap(firstImage)); Image grayFrame = bgrImage.Convert(); var faces = _cascadeClassifier.DetectMultiScale(grayFrame, 1.01, 1, Size.Empty); foreach (var face …

Hi all, here is a small program I have worked on over these last two days, I have submitted it in the hopes of some constructive criticism and suggestions (please be kind, this is one of my earlier C projects lol). This is a small console application that simulates a contact management database. The data that a user inputs is saved to an external dat file (contactdatabase.dat) which is created the first time a user saves and exits. This project also employs the use of Malloc(), which is used to allocate memory on the fly (at runtime) for dynamic data …

Hi all, I'm having some issues with the Scanner not waiting for input from the keyboard. The first method processChoice takes the userChoice and the idea is that in the switch statement there is a call to a method getUserInputForProcessing that takes the action and there scanner takes an input but it's not passing the control to the keyboard, it goes directly to the Exception because nextLine is empty, not entirely sure why. Is that because it's inside a switch statement? public void processChoice(int userChoice, BookManager bookManager) { switch(userChoice) { case 0: System.out.println("Goodbye."); System.exit(0); break; case 1: System.out.println("You chose READ"); …
