RE: [DUG]: Passing DataSet to Quick Report

[James Low]

Possibly an answer to two question in one:   First, I assume you shouldnt pass the Dataset name, pass the Dataset object (TDataset) - which is just a pointer anyway.   Regarding the variables thing the ideal is to write code that is self documenting and as self contained as possible. A procedure that depends on a global variable to operate correctly requires someone to explain that fact, and is less portable (what say that global variable has a different name in another program?). That said, class methods often rely on form level variables - but they are always part of the class that has these variables so, again, things are self contained.   Avoid using global variables, but not too an extreme. Often you'll want to, say, remember the state of a grid (edited/ not edited) and a procedure will need to chck out this global variable to, say, disable/enable buttons ... thats fair enough. But make sure its easy to follow - the variables are clearly named etc. [James Low]  -----Original Message----- From: Mark Howard [mailto:[EMAIL PROTECTED]] Sent: 3 May 2001 09:51 To: Multiple recipients of list delphi Subject: [DUG]: Passing DataSet to Quick Report Hi All   I would like to pass a Dataset name to a Quick Report but am not sure how to go about this.   I have something like:   with QueryDataModule.Query1 do     begin       Close;       DatabaseName := MainForm.DatabaseName;       SQL.Clear;       SQL.Add('Select stuff from Tables);       Open;     end;     Application.CreateForm(TBCInv, BCInv);     if OutMode = 'Screen' then BCInv.Report.Preview           else BCInv.Report.Print;   What I want to do is pass QueryDataModule.Query1 to BCInv on this occaision and some other dataset to it on another occaision.   Has anyone some code snippets that demonstrate this?   TIA   Mark
