]WebQueryConnection class
Specifies the properties for a web query source. A web query will retrieve data from HTML tables, and can also supply HTTP “Get” parameters to be processed by the web server in generating the HTML by including the parameters and parameter elements.
public class WebQueryConnection : ExternalConnection
Properties
| Name | Description |
|---|---|
| BackgroundRefresh { get; set; } | Indicates whether the connection can be refreshed in the background (asynchronously). true if preferred usage of the connection is to refresh asynchronously in the background; false if preferred usage of the connection is to refresh synchronously in the foreground.(Inherited from ExternalConnection.) |
| override ClassType { get; } | Gets the type of this ExternalConnection object. |
| virtual Command { get; set; } | The string containing the database command to pass to the data provider API that will interact with the external source in order to retrieve data(Inherited from ExternalConnection.) |
| virtual CommandType { get; set; } | Specifies the OLE DB command type. 1. Query specifies a cube name 2. Query specifies a SQL statement 3. Query specifies a table name 4. Query specifies that default information has been given, and it is up to the provider how to interpret. 5. Query is against a web based List Data Provider.(Inherited from ExternalConnection.) |
| ConnectionDescription { get; set; } | Specifies the user description for this connection(Inherited from ExternalConnection.) |
| override ConnectionFile { get; } | Gets the connection file. |
| ConnectionId { get; } | (Obsolete.) Specifies The unique identifier of this connection.(Inherited from ExternalConnection.) |
| virtual ConnectionString { get; set; } | The connection information string is used to make contact with an OLE DB or ODBC data source.(Inherited from ExternalConnection.) |
| Credentials { get; set; } | (Obsolete.) Specifies the authentication method to be used when establishing (or re-establishing) the connection.(Inherited from ExternalConnection.) |
| CredentialsMethodType { get; set; } | Specifies the authentication method to be used when establishing (or re-establishing) the connection.(Inherited from ExternalConnection.) |
| EditPage { get; set; } | (Obsolete.) The URL of the user-facing web page showing the web query data. This URL is persisted in the case that sourceData=“true” and url has been redirected to reference an XML file. Then the user-facing page can be shown in the UI, and the XML data can be retrieved behind the scenes. |
| EditWebPage { get; set; } | The URL of the user-facing web page showing the web query data. This URL is persisted in the case that sourceData=“true” and url has been redirected to reference an XML file. Then the user-facing page can be shown in the UI, and the XML data can be retrieved behind the scenes. |
| HtmlFormat { get; set; } | How to handle formatting from the HTML source when bringing web query data into the worksheet. Relevant when sourceData is True. |
| Id { get; } | Gets the id of the connection.(Inherited from ExternalConnection.) |
| IsConsecutive { get; set; } | Flag indicating whether consecutive delimiters should be treated as just one delimiter. |
| IsDeleted { get; set; } | Indicates whether the associated workbook connection has been deleted. true if the connection has been deleted; otherwise, false.(Inherited from ExternalConnection.) |
| IsHtmlTables { get; set; } | Flag indicating whether web queries should only work on HTML tables. |
| IsNew { get; set; } | True if the connection has not been refreshed for the first time; otherwise, false. This state can happen when the user saves the file before a query has finished returning.(Inherited from ExternalConnection.) |
| IsParsePre { get; set; } | Flag indicating whether data contained within HTML PRE tags in the web page is parsed into columns when you import the page into a query table. |
| IsSameSettings { get; set; } | Flag indicating whether to parse all tables inside a PRE block with the same width settings as the first row. |
| IsTextDates { get; set; } | Flag indicating whether dates should be imported into cells in the worksheet as text rather than dates. |
| IsXl2000 { get; set; } | This flag exists for backward compatibility with older existing spreadsheet files, and is set to true if this web query was refreshed in a spreadsheet application newer than or equal to Microsoft Excel 2000. This is an optional attribute that can be ignored. |
| IsXl97 { get; set; } | This flag exists for backward compatibility with older existing spreadsheet files, and is set to true if this web query was created in Microsoft Excel 97. This is an optional attribute that can be ignored. |
| IsXml { get; set; } | true if the web query source is XML (versus HTML), otherwise false. |
| IsXmlSourceData { get; set; } | Flag indicating that XML source data should be imported instead of the HTML table itself. |
| KeepAlive { get; set; } | True when the spreadsheet application should make efforts to keep the connection open. When false, the application should close the connection after retrieving the information.(Inherited from ExternalConnection.) |
| Name { get; set; } | Specifies the name of the connection. Each connection must have a unique name.(Inherited from ExternalConnection.) |
| OdcFile { get; set; } | Specifies the full path to external connection file from which this connection was created. If a connection fails during an attempt to refresh data, and reconnectionMethod=1, then the spreadsheet application will try again using information from the external connection file instead of the connection object embedded within the workbook.(Inherited from ExternalConnection.) |
| OnlyUseConnectionFile { get; set; } | Indicates whether the spreadsheet application should always and only use the connection information in the external connection file indicated by the odcFile attribute when the connection is refreshed. If false, then the spreadsheet application should follow the procedure indicated by the reconnectionMethod attribute(Inherited from ExternalConnection.) |
| Parameters { get; } | Gets ConnectionParameterCollection for an ODBC or web query.(Inherited from ExternalConnection.) |
| Post { get; set; } | Returns or sets the string used with the post method of inputting data into a web server to return data from a web query. |
| virtual PowerQueryFormula { get; } | Gets the definition of power query formula.(Inherited from ExternalConnection.) |
| ReconnectionMethod { get; set; } | (Obsolete.) Specifies what the spreadsheet application should do when a connection fails. The default value is ReConnectionMethodType.Required.(Inherited from ExternalConnection.) |
| ReconnectionMethodType { get; set; } | Specifies what the spreadsheet application should do when a connection fails. The default value is ReConnectionMethodType.Required.(Inherited from ExternalConnection.) |
| RefreshInternal { get; set; } | Specifies the number of minutes between automatic refreshes of the connection.(Inherited from ExternalConnection.) |
| RefreshOnLoad { get; set; } | True if this connection should be refreshed when opening the file; otherwise, false.(Inherited from ExternalConnection.) |
| SaveData { get; set; } | True if the external data fetched over the connection to populate a table is to be saved with the workbook; otherwise, false.(Inherited from ExternalConnection.) |
| SavePassword { get; set; } | True if the password is to be saved as part of the connection string; otherwise, False.(Inherited from ExternalConnection.) |
| virtual SecondCommand { get; set; } | Specifies a second command text string that is persisted when PivotTable server-based page fields are in use. For ODBC connections, serverCommand is usually a broader query than command (no WHERE clause is present in the former). Based on these 2 commands(Command and ServerCommand), parameter UI can be populated and parameterized queries can be constructed(Inherited from ExternalConnection.) |
| SourceFile { get; set; } | Used when the external data source is file-based. When a connection to such a data source fails, the spreadsheet application attempts to connect directly to this file. May be expressed in URI or system-specific file path notation.(Inherited from ExternalConnection.) |
| SourceType { get; set; } | Gets or Sets the external connection DataSource type.(Inherited from ExternalConnection.) |
| SSOId { get; set; } | Identifier for Single Sign On (SSO) used for authentication between an intermediate spreadsheetML server and the external data source.(Inherited from ExternalConnection.) |
| Type { get; set; } | (Obsolete.) Gets or Sets the external connection DataSource type.(Inherited from ExternalConnection.) |
| Url { get; set; } | URL to use to refresh external data. |
