Delphi ODBC连接对话框组件？

Question

我正在考虑将ODBC数据库连接添加到应用程序.

用户将在运行时配置并选择其数据库odbc连接.

是否有任何组件可以提供所需的一系列对话框？

允许用户选择数据源类型,选择驱动程序,浏览已定义的ODBC连接等.

干杯萨姆

Answer 1

如果您使用的是ADO组件,可以试试这个.

选项1

  Uses
    OleDB,
    ComObj,
    ActiveX;

    function Edit_ADO_ODBC_ConnectionString(ParentHandle: THandle; InitialString: WideString;out NewString: string): Boolean;
    var
      DataInit  : IDataInitialize;
      DBPrompt  : IDBPromptInitialize;
      DataSource: IUnknown;
      InitStr   : PWideChar;
    begin
      Result   := False;
      DataInit := CreateComObject(CLSID_DataLinks) as IDataInitialize;
      if InitialString <> '' then
      DataInit.GetDataSource(nil, CLSCTX_INPROC_SERVER, PWideChar(InitialString),IUnknown, DataSource);
      DBPrompt := CreateComObject(CLSID_DataLinks) as IDBPromptInitialize;

      {
      DBPROMPTOPTIONS_WIZARDSHEET = $1;
      DBPROMPTOPTIONS_PROPERTYSHEET = $2;
      DBPROMPTOPTIONS_BROWSEONLY = $8;
      DBPROMPTOPTIONS_DISABLE_PROVIDER_SELECTION = $10;
      }
      if Succeeded(DBPrompt.PromptDataSource(nil, ParentHandle,DBPROMPTOPTIONS_PROPERTYSHEET, 0, nil, nil, IUnknown, DataSource)) then
      begin
        InitStr   := nil;
        DataInit.GetInitializationString(DataSource, True, InitStr);
        NewString := InitStr;
        Result    := True;
      end;
    end;



Result:=Edit_ADO_ODBC_ConnectionString(0,OldConnectionString,NewString);

选项2

Uses
ADODB;

PromptDataSource(Self.Handle, InitialString);

选项3

Uses
ADODB,
AdoConEd;

procedure TMainForm.Button2Click(Sender: TObject);
Var
ADOConnection1 : TADOConnection;
begin
   ADOConnection1:=TADOConnection.Create(Self);
   EditConnectionString(ADOConnection1);
end;

您必须选择"用于ODBC驱动程序的Microsoft OLE DB提供程序"

再见.
