Haven't programmed in a long time. Last project was a GCODE pathway generator I wrote several years back. My compiler is obviously several years out of date. Uses time(), itoa(), rand(). Current standard compliant compilers should have <chrono>, <thread>, <random>, and to_string() in suppliment to those more deprecated functions. This is a very simple, high speed method of generatinga alot of randomized junk data onto your drive. Make sure you have about 300MB of RAM available for the overhead. An older non-SSD might croak. Useful for making old files unrecoverable by overwriting the old space on a drive. Doesn't go …

This was a query raised by one of a forum members at another site, where he had a worksheet filled with random numbers, and I have already answered that query [at my post here](https://vbacoder1962.wordpress.com/2019/07/15/extracting-cell-phone-numbers-from-random-strings-of-variable-length/). You may go through that post and read the logic behind the code. ![vbacoder_Code_20190715.jpg](/attachments/large/4/160efbe4e4d0a8400d04653a6e420c7b.jpg)

This simple isprime(number) function checks if the given integer number is a prime number and returns True or False. The function makes sure that the number is a positive integer, and that 1 is not considered a prime number. To find out if an integer n is odd one can use `n & 1`, to check for even one can then use `not n & 1` or the more traditional `n % 2 == 0` which is about 30% slower.

The printer seems to be a much ignored computer peripheral when it comes to programming. This little code snippet explores one way to send text to the default printer. It actually draws the text into an imaginary box on the paper. You can specify the upper left and lower right corners of this box.

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; …

You might be familiar with the dreaded blank page when your PHP script doesn't work. Here's how to spit out errors to the screen, instead of getting just a blank page, as well as logging errors to a file.

There are two ways to write to a file in PHP. You can either open a stream, and write to it in parts, or you can use `file_put_contents()` which is much more convenient, with the trade off being that it takes up much more memory, and is not ideal if you want to send a *lot* of data upstream.

If you need your PHP script to redirect to a different website, you can send an HTTP header to do that. Remember, `header()` must be called before any actual output is sent, which includes not just HTML, but blank lines, etc.. as well.

We have a Swagger file for our API, but in our API documentation, we want to show valid responses for each endpoint. I coded up this little recursive function in PHP which takes our Swagger file and spits out a valid response. I use it as follows, for each individual endpoint: // $swagger is the entire swagger file $swagger = file_get_contents('/path-to-swagger.json'); For the below code within our PHP template, `$endpoint` can be assumed to be a single endpoint with method (e.g. a single POST request to a URI) such that json_decode() was used to convert it from the Swagger file …

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 …

If you press any key on your keyboard, this small Tkinter GUI program will tell you which key and what type of key has been pressed. Great for applications where a simple key stroke is required.

vbScript - Extending Application Functionality with vbScript and AutoIt Sometimes you'll find that one of your favourite applications is missing some useful functionality. For me, it was FastStone Image Viewer. I've had to scan a large number of family photos to convert everything to digital. Rather than scan one photo at a time, I found it faster to fill the scanner and scan an entire page at once. That reduces the overall scan time but it means that I have to crop and save each individual photo from the gang scans. FastStone has a crop board where I can select …

...was asked for some php file upload code, so I thought I would post some stripped down, barebones code that I use in admin/dashboard pages to add/change images associated with products. Please see attached image for folder setup. The code uses the [jQuery Form](http://malsup.com/jquery/form/) plugin by Mike Alsup. **index.php** has two forms; one for the image uploads and the other to show where you would have your "product add/update" form. Files are immediately uploaded to a tmp directory whenever you select an image. If you change your mind a few times you can end up with lots of images in …

Demonstrates using .NET Remoting to broadcast to client subscribers. There are three parts: 1) Server.cs - for console app responsible for broadcasting messages (date/time stamp currently) 2) Client.cs - for console app that registers with server to subscribe to broadcasts 3) Agent.cs - class library that facilitates/eposes the interfaces for our client/server communication To use, create the three project types defined above and include the appropriate code found in this snippet. In both the Server and Client projects, add references to the Agent.DLL project. Then, modify the IP address in the ClientClass's creation of the AbstractServer remoteObject to a string …

An example showing how to use the wx.media.MediaCtrl() widget to play MIDI, MP3, WAV, AU, AVI and MPG audio and video files. I have only tested it with Windows. If you are very ambitious, you could use a random graphics display with the sound, or tie the slider position to a slide presentation.

This short Python code gets the local time from the PC as a formatted string using time.strftime('%H:%M:%S'). The time string is displayed in a label using a larger font. A recursive function checks the time five times per second, and updates the time string, if it has changed. Five times per second may sound like overkill, but keeps the display from acting spasmodic.

Let's say you want to send a short private message to your friend, but don't want grandma to snoop around and find it. One way is to use the Python Image Library (PIL) and hide the message in a picture file's pixels. Just looking at the picture you will barely detect any difference between the before and after picture. All your friend needs is the decode_image portion of this simple code to get the message back.

Hello Daniweb Community, I have been talking on a couple [Facebook](http://www.facebook.com) groups such as sale pages where you post your own stuff for people to buy. Most groups like this have rules about bumping like once per day, every 12 hours etc... So it got to the point where it became annoying to have to bump my posts every so oftern so I managed to construct this script that'll do it automatically with the help of a cronjob that can be set to bump at whatever time you like. So I have made a simple easy to use (ha may …
