Question:
How do I pass arrays from VB to Delphi?
Answer:
Arrays can be passed as variants:
VB module code:
Attribute VB_Name = "Module1"
Declare Function TestMin Lib "c:\windows\system\NoelSArr"
(Nums As Variant) As Integer
VB form code:
Dim A As Variant
Private Sub Command1_Click()
A = Array(4, 3)
MsgBox (TestMin(A))
End Sub
Delphi DLL code:
library NoelSArray;
.
.
function TestMin(const Nums: Variant): integer; export; stdcall;
var
p1: Variant;
begin
p1 := VarArrayCreate([0, 1], VT_I4);
p1:= Nums;
if (p1[0] < p1[1]) then
result:= p1[0]
else
Result:= p1[1];
end;
