Schleife mit else stoppen!!!???

[himitsu]

Bei dir war vorher nur "Combobox1.AddItem(Combobox1.Text,nil);" in der If-Anweisung drin, also kein Wunder, wenn der Rest ausgeführt wurde.

Code:

procedure TFrame5.Button1Click(Sender: TObject);
var
LI: TListItem;
q :string;
begin
if Combobox1.Text =('') then
   Showmessage('Bitte geben Sie einen Suchbegriff ein')
   else [color=red]begin[/color]
Combobox1.AddItem(Combobox1.Text,nil);
Combobox1.Items.SaveToFile(ExtractFilePath(ParamStr(0))+'Protocoll.pnmd');
q:= '%' + Combobox1.Text + '%';
with ZReadOnlyQuery1 do
  begin
    close;
    SQL.Clear;
    SQL.Add('SELECT * FROM Addy WHERE');
    SQL.Add('Name LIKE :Name OR ');
    SQL.Add('Vorname LIKE :Vorname OR ');
    SQL.Add('Straße LIKE :Straße OR ');
    SQL.Add('PLZ LIKE :PLZ OR ');
    SQL.Add('Stadt LIKE :Stadt OR ');
    SQL.Add('e-Mail LIKE :e-Mail OR ');
    SQL.Add('Tel LIKE :Tel OR ');
    SQL.Add('Notiz LIKE :Notiz');
    ParamByName ('Name').AsString := q;
    ParamByName ('Vorname').AsString := q;
    ParamByName ('Straße').AsString := q;
    ParamByName ('PLZ').AsString := q;
    ParamByName ('Stadt').AsString := q;
    ParamByName ('e-Mail').AsString := q;
    ParamByName ('Tel').AsString := q;
    ParamByName ('Notiz').AsString := q;
    open;
    ListView1.Items.BeginUpdate;
    Listview1.Items.Clear;
    while not (EOF) do
    begin
      LI := Listview1.Items.Add;
      LI.ImageIndex := 0;
      LI.Caption := (FieldByName('ID').AsString);
      LI.SubItems.Add(FieldByName('Name').AsString);
      LI.SubItems.Add(FieldByName('Vorname').AsString);
      LI.SubItems.Add(FieldByName('Straße').AsString);
      LI.SubItems.Add(FieldByName('PLZ').AsString);
      LI.SubItems.Add(FieldByName('Stadt').AsString);
      LI.SubItems.Add(FieldByName('e-Mail').AsString);
      LI.SubItems.Add(FieldByName('Tel').AsString);
      LI.SubItems.Add(FieldByName('Notiz').AsString);
      Next; 
    end; 
    ListView1.Items.EndUpdate; 
    close; 
  end;
[color=red]end;[/color]
end;

Hier noch 'ne Möglichkeit.

Exit beendet die Prozedur und der nachfolgende Code wird auch nicht mehr ausgeführt

Code:

procedure TFrame5.Button1Click(Sender: TObject);
var
LI: TListItem;
q :string;
begin
if Combobox1.Text =('') then
   Showmessage('Bitte geben Sie einen Suchbegriff ein')
   else [color=red]exit;[/color]
Combobox1.AddItem(Combobox1.Text,nil);
Combobox1.Items.SaveToFile(ExtractFilePath(ParamStr(0))+'Protocoll.pnmd');
q:= '%' + Combobox1.Text + '%';
with ZReadOnlyQuery1 do
  begin
    close;
    SQL.Clear;
    SQL.Add('SELECT * FROM Addy WHERE');
    SQL.Add('Name LIKE :Name OR ');
    SQL.Add('Vorname LIKE :Vorname OR ');
    SQL.Add('Straße LIKE :Straße OR ');
    SQL.Add('PLZ LIKE :PLZ OR ');
    SQL.Add('Stadt LIKE :Stadt OR ');
    SQL.Add('e-Mail LIKE :e-Mail OR ');
    SQL.Add('Tel LIKE :Tel OR ');
    SQL.Add('Notiz LIKE :Notiz');
    ParamByName ('Name').AsString := q;
    ParamByName ('Vorname').AsString := q;
    ParamByName ('Straße').AsString := q;
    ParamByName ('PLZ').AsString := q;
    ParamByName ('Stadt').AsString := q;
    ParamByName ('e-Mail').AsString := q;
    ParamByName ('Tel').AsString := q;
    ParamByName ('Notiz').AsString := q;
    open;
    ListView1.Items.BeginUpdate;
    Listview1.Items.Clear;
    while not (EOF) do
    begin
      LI := Listview1.Items.Add;
      LI.ImageIndex := 0;
      LI.Caption := (FieldByName('ID').AsString);
      LI.SubItems.Add(FieldByName('Name').AsString);
      LI.SubItems.Add(FieldByName('Vorname').AsString);
      LI.SubItems.Add(FieldByName('Straße').AsString);
      LI.SubItems.Add(FieldByName('PLZ').AsString);
      LI.SubItems.Add(FieldByName('Stadt').AsString);
      LI.SubItems.Add(FieldByName('e-Mail').AsString);
      LI.SubItems.Add(FieldByName('Tel').AsString);
      LI.SubItems.Add(FieldByName('Notiz').AsString);
      Next; 
    end; 
    ListView1.Items.EndUpdate; 
    close; 
  end;
end;
