VB to Xojo

Getting Started
1

Trying to transfer a VB program to xojo, what are the alternatives for ln, Fix and int? Thank you.

2

Look here Migrating from Visual Basic

3

How do i use the library(VB-master)?

4

This request (on yahoo):
site:www.microsoft.com VB-master

returns nothing.

5

https://github.com/xojo/VB

It is mentioned in the readme.md

Download the Zip-file from GitHub and unzip it.
Open XojoVB.xojo_project in Xojo and copy the VB module (with globe icon) in your own project.

And what will this change? I did it and it still can’t realize what int and fix means

8

Window1.PushButton1.Action, line 10
This item does not exist
j = Fix(f)

  • did you declare f and j within the scope of the action method? One thing that was easy to do with VB was to declare global variables. Xojo is a bit more strict. A good habit is to declare variables only where you are going to use them.
  • did you assign a numeric value to f?

If you did, then try with .fix where the module name is the name of the module containing the FIX function.

From the Xojo.VB ReadMe:

So use it like this:

Dim f As Double = -8.4 Dim j As Integer = VB.Fix(f)

12

Oh, it worked, thanks a lot! But what should i do with Log10, CInt(to integer) and CSng(to single)?

13

Log10, CInt(to integer) and CSng(to single)?

Log10 of N =

log(n) / log(10)

CInt (N) =

Floor(n)     as long as the number is positive

Csng (n) =

dim s as single s = n return s

14

it started working with a little bit different numbers in results then in VB(0,168 in VB, 0,169 in Xojo), but thats fine. Huge thanks! Hope ill get used to Xojo soon.
