Yep :)
I am not sure... Does this work in newer versions of 4D, or is this
something that should be entered as a bug?
Array text(My_2D-Array;5;10)
c_pointer($ptr;$ptr2)
$ptr:=->My_2D_Array
$ptr2:=->$ptr->{1} // <- this fails : Field variable or table expected
$ptr2:=->($ptr->{1}) // this fails : Field variable or table expected
$test:=$ptr->{1} // as expected this gets the value of the array at
$ptr->{1} element zero
I found a solution (workaround actually)
- As Keisuke suggested COPY ARRAY will resolve the specific
problem.(Implemented)
So:
// method to get table names etc
// For each table - get table info and if appropriate get field info
COPY ARRAY($Name_Array->{$i};$Temp_Names)
//$Name_Array is a pointer to a 2D Text array
//$Temp_Names is a 1D Text array
utl_struct_Field_Arrays ($i;->$Temp_Names) //populate Temp array with
field names for table $i
COPY ARRAY($Temp_Names;$Name_Array->{$i}) // copies the temp array to
the correct place in 2D array
The actual method allows the creation of upto 3 2D arrays, at the same
time, for table information
Table & Field names
Table and Field numbers
Table and Field pointers
THANKS Everyone for the help
