In this snippet we are playing around with wxPython's buttons, showing you how to bind the mouse click event, enable and disable, show and hide the buttons. Each button also has a tool-tip (hint) associated with itself.

If you want a variable in a C function to retain its last assigned value, you simply declare it as static. Python does not have static variables, but you can impersonate one in different ways. The default list argument is my preferred option. Here are some examples.

Returns the duplicate value in array t[n], which contains numbers 1 to n-1. Given two approaches with O(n) and O(n-square) complexities.

Return Nth the node from the end of the linked list. Time Complexity is O(n).

FASM can output an executable PE directly, but sometimes you want to output an object file for linking with modules in other languages. The following program can be used to link with the C library of the GCC compiler with the following commands: C:\>fasm hello.asm hello.obj C:\>gcc hello.obj -o hello.exe …

Some languages are hard to get started in. FASM appears to be one of these languages because the documentation is not detailed enough for a beginner. That's a shame because FASM is (in my opinion) one of the better assemblers. The following snippet is a simple Hello, world! program which …

Just in time, a short Python code snippet to calculate the date of Easter Sunday of a given year. This can be expanded to calculate the important date of Mardi Gras too.

I took the data of an old State Trivia game and applied it to Python. The data forms a series of lists with matching indexes. One example of how to ask a trivia question, present four possible answers, and how to evaluate the correct answer is given. You can expand …

The Relative of push is pop. Pop removes the last item in an Array, and returns the value into a single (scalar) variable. Again, due To VB Limitations, this one works on strings.

Simple Function To Simulate The Push Command, due to VB's limitations, This one is Specific To Strings. (Simple enough to modify for integers or variants, etc)

This is a little code for a shell that allows for simple redirection and multiple yes! MULTIPLE piping abilities. It is slightly glitched for background processes, and this is only my second program written with C/C++ so it looks to be quite inefficient, but the piping works pretty nicely. The …

The little program allows eye patients to test their color skills. They are given a random color rectangle by the computer and are then asked to match the color as closely as they can using sliders of the three basic colors. An evaluation button examines the closeness of the results.
