    Inheritance Question

    All that's true, and I know that! We are just one step close to solution! I need code that will be Free (and nil) closed descendant Form: procedure TGForm.FormClose(Sender: TObject; var Action: TCloseAction); begin Action:= caFree; GForm := nil; // here need to be something different to...

    Inheritance Question

    No, there is nothing specific in closing any of TXForm, TYForm and TZForm forms! I just want to avoid duplicating actually same code on all of descending forms in their OnClose event. So, if possible, one code on TGForm that will close any (so, NOT ALL, but just concrete one!) descendant form.

    Inheritance Question

    Yes, exactly that! All that I knew before, just don't know: WHAT CODE to put in on OnClose for TGForm so that code will be recognize which exactly form is calling them - TXForm or TYForm or TZForm or... and Close that form?

    Inheritance Question

    I don't want to Free ALL FORMS of TGForm Type when one of them is Closed, but exactly that one!

    Inheritance Question

    One more attempt: I make 'generic' Form (GForm) and put them into Delphi Repository (so I DON'T create GForm in my Project, I just use them to INHERIT other forms!). GForm is ancestor for several forms in my Project: XForm, YForm, ZForm,... (all of them are created from Repository, inheriting...

    Problem with ftGuid parameter in ADOStoredProc

    I have SQL Server 2008 Stored Procedure that uses uniqueidentifier type of Parameter. When try to open ADOStoredProc1 related with this SP in my Delphi Project, this error occurs: Invalid character value for cast specification. Delphi recognizes this Parameter as ftGuid DataType. What other...

    Inheritance Question

    My intention is to Free and nil anyone of DESCENDANT Forms (TForm2 = class(TForm1), TForm3 = class(TForm2),...) trough Form1.FormClose procedure: procedure TForm1.FormClose(Sender: TObject; var Action: TCloseAction); begin Action:= caFree; Form1 := nil; // or, maybe like DjangMan says, just...

    Inheritance Question

    Yes, this was same I try first, but... Something is wrong, because when after Self.Free; // or Self := nil; (what is actually Form2 := nil) I check this condition: if not Assigned(Form2) then ... program behave like Form2 IS NOT NIL!?!?!? BobaFet, Thanks anyway!

    Inheritance Question

    Exactly that is and my question: what is <formname>?

    Inheritance Question

    Form1 is ancestor Form, and had this code in Form1.FormClose: ... Action:= caFree; Form1 := nil; end; Form2 is derived from Form1 (TForm2 = class(TForm1). What should write instead of Form1 := nil in Form1.FormClose to be sure that (inherited) Form2 is also nil after Close?

    Problem with Repository

    Delphi2007 Repository had very strange behavior: refuses to remember new Categories and new items I've add to it. Actually, I can add both of them, but next time I try to open from Repository, they didn't appear there?! Configuration: Delphi2007 for Win32® R2 Version 11.0.2902.10471, Windows 7...

    Unable to Run Computer management from context menu

    No, I'm trying to find 'native' solution (some Microsoft update, fix or similar)...

    Unable to Run Computer management from context menu

    Tnx, but can't believe that Microsoft did not solve this common problem in Win 7.

    Unable to Run Computer management from context menu

    Right click on Computer icon on Desktop, then Manage and following error occurs: "The file does not have a program associated with it for performing tis action.(...)" When starts Computer management from Administrative tools, everything is OK. Any idea?
