IDtWebProvider.HasHeader

Syntax

HasHeader: Boolean;

Description

The HasHeader property determines whether field headers are imported from the first table row.

Comments

By default the property is set to True, and field headers are imported from the first table row. If the property is set to False, the first row is regarded as a row with data.

Example

Executing the example requires that the repository contains an ETL task with the ETL identifier and the Data.html file in the root of the C disk.

Sub UserProc;
Var
    MB: IMetabase;
    MObj: IMetabaseObject;
    EtlTask: IEtlTask;
    EtlProvider: IEtlPlainDataProvider;
    WebProvider: IDtWebProvider;
    WxProvider: IWxRectangle;
    WxETLProvider: IWxETLObject;
Begin
    MB := MetabaseClass.Active;
    // ETL task search. Repository object with the ETL identifier
    MObj := MB.ItemById("ETL").Edit;
    EtlTask := MObj As IEtlTask;
    // Start of data provider creation
    // Create the "Import from Web" object
    EtlProvider := EtlTask.Create(EtlObjectType.PlainDataWebProvider) As IEtlPlainDataProvider;
    EtlProvider := EtlProvider.Edit;
    EtlProvider.Id := "Web_Provider";
    EtlProvider.Name := "Import from Web";
    EtlProvider.Description := "Import from Web";
    // Set up data provider
    WebProvider := EtlProvider.Provider As IDtWebProvider;
    WebProvider.HasHeader := True;
    WebProvider.TableIdentificationType := DtWebTableIdentificationType.ByNumber;
    WebProvider.TableNumber := 1;
    WebProvider.Url := "c:\Data.html";
    EtlProvider.FillDefault;
    // Save data provider
    EtlProvider.Save;
    // End of data provider creation
    // Start of visual object creation
    WxProvider := EtlTask.Workspace.CreateRectangle;
    WxETLProvider := New WxETLObject.Create;
    WxETLProvider.ETLObject := EtlProvider;
    WxProvider.Style.TextPosition := WxTextPosition.Bottom;
    WxProvider.Style.PictureMarginTop := -10;
    WxProvider.PinPosition := New GxPointF.Create(50, 50);
    WxProvider.Extension := WxETLProvider As IWxShapeExtension;
    // End of visual object creation
    // Save ETL task
    MObj.Save;
End Sub UserProc;

After executing the example the Import from Web object is created in the ETL task. This data provider imports data from the HTML file. The first available table in the file is imported. Field names are imported from the first table row.
