Hello,
I am a new in Xojo , come from VB6 and wanted to use to program iOS apps as a hobby.
Where I have some problems to understanding is :
In VB6 I could be a variable or array when the program starts assign
" Global xyz ( 10 ) as String "
and throughout the program to access it. How it works in iOS Xojo or how can I pass to the next view.
Thank you for a help determine which is a little something for most professionals .
Thanks Gerd
Create a module called “Globals”. In that module add the global property you want (yz(10) as String), with the scope “Public”.
And then access the variable from anywhere in your application!
i have done what you wrote, but i get this following error message
NilObjectExeption
do you know, what’s my error ?
We need more information. What line is throwing the nil object exception? Showing code will be helpful.
OK, in the event activated in the view, i must write this code
if ValueXYZ = nil then
ValueXYZ = new Value
end if

You can’t use arrays as return values in computed properties (or shared computed properties). Instead you must create a method (or shared method):
Function KanalWert() As YourClass()
Return your array here
End
