Title: You need Dynamic ADO object?
Question: What shall i do when need to Create many Dynamic ADO object?
Answer:
Create an array of ADOTable or ADOQuery at nuber you think need!
Because you can't find The Dynamic Object that created at other Function or Procedure (test it to be sure)!
type // define custom table
Dynamic_ado=record
ado_t: TADOTable ; // ADO object
name: string ; // name of ADO object
end ;
var
ADOT: array [0..100] of Dynamic_ado ;
Function createado(name:string;connection:TADOConnection):Boolean ;
var
i: SHORT ;
begin
i:=0 ;
While TRUE do
begin
if adot[i].name='' then
begin
try
result:=True ;
adot[i].ado_t:=TADOTable.create(nil) ;
adot[i].ado_t.Connection:=TADOConnection1 ;
adot[i].ado_t.tablename:='accounts' ;
adot[i].ado_t.Open ;
adot[i].name:=name ;
except
showmessage('Invalid Connection Or table name')
end ;
break ;
result:=False ;
end
else
inc(i) ;
end ;
end ;
// Moving ADOT to the next record Next
Function ado_next(name:string):Boolean ;
var
i: SHORT ;
begin
i:=0 ;
While TRUE do
begin
if adot[i].name=name then
begin
adot[i].ado_t.Next ;
result:=True ;
if adot[i].Eof then
begin
ShowMessage('End of DB') ;
result:=False ;
end ;
break ;
end
else
inc(i) ;
end ;
end ;
// You can do similar code for previous , Delete , Last , first or
// Destroy table, at last you must destroy the dataset & put it name to the '' (Nothink)
