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]” […]
Dear user, Here some thoughts about using the action command FileList as alternative to FileExists. Suppose, my music folder contains several files such as Bach-BWV545.mp3 Bach-BWV563.mp3 Bach-BWV564.mp4 Suppose further, that we make a VisualNeo Win program that checks if a specific file exists. For this task, VisualNeo has the action command FileExists: SetVar “[File]” “Bach-BWV545.mp3” […]
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 […]
What’s embedding a WebApp? WebApps can be published independently or embedded into any other website. Take a look at this interactive content and try to click on the different text signs: This is an embeded content from an independent WebApp, made with VisualNEO Web and published here: https://sinlios.com/apps/strongbox As you can see, the embedded […]
Following up on the my post Check if a particular year is a LEAP year, here is a routine to check if a date is valid. By definition, a date is valid if all of these conditions are true … a) The year is an integer greater than or equal to 0 b) The month […]
By definition, a year is a LEAP year if all of these conditions are true … a) The number is a whole multiple of 4 b) If the number is a whole multiple of 100 it is also a whole multiple of 400 So, 1600 and 2000 are LEAP years … but 1700, 1800, 1900 […]
If your VisualNEO Win application needs to display a count up (or down) of time elapsed (or remaining) … in hours, minutes and seconds … formated as HH:MM:SS … the idea/subroutine described below will help you to do this. First, create a Timer object called tc … configure it so … Start: is set to […]
For ListBox (or ComboBox) objects whose contents (items) remain unchanged, you just type the items into the List Items field at Design time. However, there are times when you require a different set of items to be loaded into such Boxes every time the VisualNEO Win created application is run … or the items are […]
Here, I described how you can make a random selection from a list of items … but there are times when you need to make such random selections without repeating any of the selections … this article details how you would go about implementing this with VisualNEO for Windows. In your App’s StartUp section … […]
Often, in VisualNEO for Windows, there is a need to make a random selection from a list of items … e.g. a list of fruits or vegetables or countries etc. … this article details how you would go about implementing this with VisualNEO Win. In your pub’s StartUp section … code something like this … […]
