How to assign multiple TEdit fields to variables
Problem/Question/Abstract:
Is there an easier way to assign multiple Edit fields to variables without individually setting each one? Here is a sample code.
type
testrec = record
fees: array[1..10] of string[65];
end;
var
dat: testrec;
procedure FormToDat;
begin
fees[1] := Edit1.Text;
fees[2] := Edit2.Text;
fees[3] := Edit3.Text;
fees[4] := Edit4.Text;
{ ... }
end;
This sample code seems inefficient and I'm thinking there might be an easier way to do this.
Answer:
There are a wide variety of ways to do this in Delphi, here's one:
var
I: Integer;
C: TComponent;
begin
for I := 1 to 10 do
begin
C := FindComponent('Edit' + IntToStr(I));
if C is TEdit then
TEdit(C).Text := Fees[1];
end;
end;
You could also store references to the edits in a TList or an array, or you could also iterate through the Controls or Components properties.
