Por Daniel Jose Sobrinho
Olá, eu tenho um memo em Delphi com as seguintes linhas
CALDO DE GALINHA
LEMON PEPPER
Preciso que fique com 10 ponto e virgula, já contando os que vão estar no espaço em branco assim:
CALDO;DE;GALINHA;;;;;;;;
LEMON;PEPPER;;;;;;;;;
Pra substituir os espaços em branco já usei o stringreplace e funcionou corretamente:
memo1.text := StringReplace(memo1.text,',',';',[rfReplaceAll]);

Por jjunior100
Preciso armazenar o total das páginas de um determinado documento em uma variável no delphi. Sei como inserir a informação no modelo MSWord.Selection.Fields.Add( Range:=MSWord.Selection.Range, Type:=wdFieldEmpty, Text:= 'NUMPAGES * Arabic ', PreserveFormatting:=True);
mas como armazenar essa informação em uma variável tipo integer? Obrigado

Bom dia,
Preciso de ajuda ajuda para resolver o problema de SIGSEGV, basicamente tennho um zconection dentro de uma classe e recebo erro quando tento acessá-lo. Segue um trecho da classe:
unit unt_classconexao; {$mode objfpc}{$H+} interface uses Classes, SysUtils, ZConnection, ZDataset; type { tConexao } tConexao = class private public vConector : TZConnection; function Listar_Usuarios:TZReadOnlyQuery; procedure Conectar_Banco; end; implementation { tConexao } function tConexao.Listar_Usuarios: TZReadOnlyQuery; var zrquery : TZReadOnlyQuery; begin Conectar_Banco; try zrquery := TZReadOnlyQuery.Create(nil); zrquery.Connection := vConector; zrquery.SQL.Clear; zrquery.SQL.Text := 'SELECT * from tbl_profissionais'; zrquery.Open; Listar_Usuarios := zrquery; finally end; end; procedure tConexao.Conectar_Banco; begin //vConector := TZConnection.Create(nil); vConector.HostName := 'localhost'; vConector.Port := 3306; vConector.Database := 'Caps'; vConector.Protocol := 'mysql-5'; vConector.User := 'root'; vConector.Password := ''; vConector.Connected := true; end; end. Após isso tento fazer uso dessa classe para popular um DBGrid:
unit unt_frmprincipal; {$mode objfpc}{$H+} interface uses Classes, SysUtils, DB, Forms, Controls, Graphics, Dialogs, Menus, DBGrids, ZConnection, unt_classconexao; type { Tfrm_principal } Tfrm_principal = class(TForm) DataSource1: TDataSource; DBGrid1: TDBGrid; MainMenu_frmPrincipal: TMainMenu; MenuItem_AplicativoSair: TMenuItem; N1: TMenuItem; MenuItem_AplicativoLogin: TMenuItem; MenuItem_Aplicativo: TMenuItem; procedure MenuItem_AplicativoLoginClick(Sender: TObject); private public vConexao : tConexao; end; var frm_principal: Tfrm_principal; implementation {$R *.lfm} { Tfrm_principal } procedure Tfrm_principal.MenuItem_AplicativoLoginClick(Sender: TObject); begin //vConexao := tConexao.Create; DataSource1.DataSet := vConexao.Listar_Usuarios; end; end. A mensagem de erro que recebo dá a entender que o problema ocorre logo que o zconnection começa a ser configurado, como vocês podem ver pelos trechos comentados eu tentei instanciar o componente também sem sucesso. Não tenho experiencia com POO e tenho certeza que estou cometendo um erro bobo, então peço uma explicação sobre como resolver isso. Agradeço de antemão a quem puder me ajudar.
PS. Estou usando o Lazarus.

om dia!
Durante a criação de um menu em tempo de execução com um tema aplicado, a descrição do CAPTION das Action estão ficando desconfigurados.
O erro ocorre apenas quando os menus são criados em tempo de execução, conforme imagem abaixo:

Pessoal boa noite!!
Criei um servidor datasnap e to precisando de uma ajuda agora neste pondo do lado cliente.
No meu servidor tenho um Method que se chama GetVendas para pegar as vendas.
Porem agora ´preciso passar um período para retornar as vendas, ai que não estou conseguindo montar minha url.
estou fazendo desta maneira do lado do cliente:
Preciso saber como passar a data
RESTClient1.ResetToDefaults;
RESTRequest1.ResetToDefaults;
RESTResponse1.ResetToDefaults;
RESTClient1.BaseURL := 'http://localhost:8080/datasnap/rest/TVendaControl';
RESTRequest1.Resource := '/Venda/{Status}/{CodVendedor}/{DtIni}/{DtFim}';
RESTRequest1.Method := TRESTRequestMethod.rmGET;
RestRequest1.Params.AddItem('Status',inttostr(cbbStatus.ItemIndex), TRESTRequestParameterKind.pkURLSEGMENT);
RestRequest1.Params.AddItem('CodVendedor','', TRESTRequestParameterKind.pkURLSEGMENT);
Project GestorApp.exe raised exception class EHTTPProtocolException with message 'HTTP/1.1 500 Internal Server Error'.
