Hi, Guys

     I was wondering I'm writting a application using C++Builder 3,  In
serval forms I DBComboBox acting as drop list components that generate
querys from a Oracle server. And since very limited documentation call
referencing TQuery within a DataModule I was wondering you any advice.

For Example under my product page I have a DBComboBox that under its events
properities on DropDown
I want call a Query Component thats within a DataModule and execute its SQL
Statement.

How ?
I know I can write a AnsiString Statement
Would it be something like
TDataModule->Query2->SQL(TString);

//--------------------------------------------------------------------------
-

void __fastcall TForm1::DBLookupComboBox1DropDown(TObject *Sender)
{


}
//--------------------------------------------------------------------------
-

Another thing how can I search all Header,Resource files, *.cpp, and object
files for any reference to elements that no longer exisits in the source
file.
Or how can rebuild all source files after having deleted a line of code from
one of the source files. It tends to reference a external call to a object



Last item on my list how can I bypass using a TQuery component and just
write some thing in straight c++ to access and manage data quries from a
database.
And when a generating a quries   with TQuery how can I take its output from
the sql server and display it on a dbgrid component.



Sincerely,



Edward A.
