![Remove [P] from VisualNEO Win](https://visualneo.com/wp-content/uploads/2023/11/remove-visualneo-win-420x286.jpg)
Last week I tried -inspired by challenge 033 on https://theweeklychallenge.org/challenges/– to create a VisualNeoWin program that shows the distribution of characters in a string (using the 26 characters of the ISO basic Latin alphabet a..z). Suppose the inputstring is CbcbbA than the lowercase output should be like a: 1 b: 3 c: 2 When scanning […]
Learn how to overcome Windows file naming restrictions and delete files with illegal characters using pattern matching in VisualNeoWin and VBScript. Get practical strategies and tips to handle these issues efficiently.
1. Introduction How it came about, I don’t remember. But for a year now I have been working with Perl almost daily. Perl is a great language (see reiniermaliepaard.nl/perl for my journey). It’s convenient for an infinite set of programming problems. In addition, Perl can run on different platforms (for me Windows and Linux are relevant). I […]
When you move text files between Linux, Mac and Windows -as I do-, you must be aware of the fact that the line endings in Linux, Mac and Windows are different. In Linux and Mac, LF (\n or [#10] in VisualNeo Win) is used and in Windows CRLF (\r\n or [#13][#10] in VisualNeo Win). So […]
Maybe I’m wrong, but I think that we all have the idea that a good programmer avoids Goto (in VisualNeo Win GotoLine). Articles, blog posts etc. on the web speak loud and clear about the bad practices of Goto. Spaghetti code is the result, i.e. code that has a “complex and tangled control structure, resulting […]
Rosetta Code (https://rosettacode.org/) is a website which presents “solutions to the same task in as many different languages as possible (…)”. Although programming languages have similar and different approaches in solving problems, the site could be inspiring for you, as it is for me. Read on! Last week, I was looking -just for fun – […]
In order to edit source code easily, I made a small editor with VisualNEO Win. The application has the Text Entry object MyBigCodeText. Its content is stored in the variable [MyBigCodeText]. Editing source code means in my case inserting some code tags. As an example: some source code sections have to be preceded by the […]
A few questions on the forum under General questions about VisualNEO Win were about Copy Folder with content and Delete All Files In Folder. They were answered in terms of the Windows Command Line using the VisualNeo command ‘Run‘. The Windows Command Line offers many commands that can be useful for you. Runing these commands […]
To determine if two strings are equal, I always use the If statement in a VisualNeo app. However, there is an interesting alternative. Let’s compare the first n characters of two strings. Given: two strings SetVar “[s1]” “abcdef” SetVar “[s2]” “Abcxyz” Select the first three characters from [s1] and [s2] SubStr “[s1]” “1” “3” “[s1-extract]” […]
You probably know the use of math expressions in VisualNEO Win’s SetVar: SetVar “[z]” “10” SetVar “[z]” “[z]+1” However, math expressions can be used in e.g. the control commands If, IfEx, While, WhileEx and Loop also, resulting in shorter code. I did not find a post on this topic. So I made some examples for […]
