Brauch mal Hilfe bei Tobjectlist

[Natcree]

was ist hier falsch wenn ich in form7 mein Button zur eingabe mache dann schmeisst er mich mit fehler raus und vermeist mich auf

Delphi-Quellcode:

if form7.showmodal = ......

raus hier mal der code

Delphi-Quellcode:

if Form7.Showmodal = mrOK then //diese Zeile wird blau markiert
    begin
      FObjects1.Add(Form7.Irgendwas1);
      FGesamt1 := FGesamt1 + Form7.Irgendwas1.Summe1;
      eltreestringgrid1.Cells[3, eltreestringgrid1.Row] := Form7.Irgendwas1.ErsteZahl1AsString + ' €';
      eltreestringgrid1.cells[4, eltreestringgrid1.Row] := form7.Irgendwas1.ZweiteZahl1AsString + ' €';
      eltreestringgrid1.Cells[4, eltreestringgrid1.Row] := Format('%.2n €', [FGesamt]);
      eltreestringgrid1.Cells[4, eltreestringgrid1.Row-1]:=form1.eltreestringgrid1.Cells[4,form1.eltreestringgrid1.Row-1]+' €';
      eltreestringgrid1.RowCount := eltreestringgrid1.RowCount + 1;
      eltreestringgrid1.Row := eltreestringgrid1.Row + 1;
      FObjects.Add(Form7.Irgendwas);
      FGesamt := FGesamt + Form7.Irgendwas.Summe;
      eltreestringgrid1.Cells[2, eltreestringgrid1.Row] := Form7.Irgendwas.ErsteZahlAsString + ' €';
      eltreestringgrid1.cells[4, eltreestringgrid1.Row] := form7.Irgendwas.ZweiteZahlAsString + ' €';
      eltreestringgrid1.Cells[4, eltreestringgrid1.Row] := Format('%.2n €', [FGesamt]);
      eltreestringgrid1.Cells[4, eltreestringgrid1.Row-1]:=form1.eltreestringgrid1.Cells[4,form1.eltreestringgrid1.Row-1]+' €';
      eltreestringgrid1.RowCount := eltreestringgrid1.RowCount + 1;
      eltreestringgrid1.Row := eltreestringgrid1.Row + 1;
     end;
end;

hier mal ein bild

[Bjoerk]

Weise dem Button im OI das ModalResult MrOk zu und formuliere:

Delphi-Quellcode:

  if ModalResult = mrOK then

[Natcree]

wo mache ich das im oi finde da nichts ist ein speed button

[Natcree]

habe nen anderen button genommen kommt immer noch fehler

[Volker Z.]

Hallo,

vermutlich scheppert es bereits irgendwo in Form7 und die Exception wird nur bis an die "blau markierte" Stelle im Programmcode "durchgereicht". Was passiert den in Form7? Quellcode wäre hilfreich.

[Natcree]

müsste an der zweiten objecktlist liegen vorher mit der ersten ging es

[Bjoerk]

Wenn diese Abfrage #1 in Form1 steht dann ist

Delphi-Quellcode:

  if Form7.Showmodal = mrOK then

soweit in Ordnung.

Sehe mir mal kurz noch form7 an ob ich da was finde..

[Bjoerk]

Ist FIrgendwas1 erzeugt und was ist eigentlich TIrgendwas?
