GetVstoObject(_Workbook)	Returns a Workbook host item that extends the functionality of the specified native workbook object.
GetVstoObject(_Worksheet)	Returns a Worksheet host item that extends the functionality of the specified native workbook object.
GetVstoObject(ListObject)	Returns a ListObject that extends the functionality of the specified native list object.

GetVstoObject(_Workbook)

Returns a Workbook host item that extends the functionality of the specified native workbook object.

public:
 Microsoft::Office::Tools::Excel::Workbook ^ GetVstoObject(Microsoft::Office::Interop::Excel::_Workbook ^ workbook);

public Microsoft.Office.Tools.Excel.Workbook GetVstoObject (Microsoft.Office.Interop.Excel._Workbook workbook);

abstract member GetVstoObject : Microsoft.Office.Interop.Excel._Workbook -> Microsoft.Office.Tools.Excel.Workbook

Public Function GetVstoObject (workbook As _Workbook) As Workbook

Parameters

workbook: _Workbook

The native workbook object for which to retrieve the extended object. Although this parameter is of type _Workbook, you typically pass a Workbook object to this method.

Returns

Workbook

The host item that extends the functionality of the native workbook object.

Examples

The following code example creates a Microsoft.Office.Tools.Excel.Workbook host item for the active Excel workbook. To use this code, run it from the ThisAddIn class in an Excel add-in project that targets the .NET Framework 4 or the .NET Framework 4.5.

Workbook vstoWorkbook =
    Globals.Factory.GetVstoObject(this.Application.ActiveWorkbook);

foreach (SmartTag st in vstoWorkbook.VstoSmartTags)
{
    System.Windows.Forms.MessageBox.Show(st.Caption);
}

Dim vstoWorkbook As Workbook = _
    Globals.Factory.GetVstoObject(Me.Application.ActiveWorkbook)

For Each st As SmartTag In vstoWorkbook.VstoSmartTags
    System.Windows.Forms.MessageBox.Show(st.Caption)
Next

Remarks

Call this method in an application-level add-in to customize any workbook that is open in Excel. This method generates a new Microsoft.Office.Tools.Excel.Workbook object if no such object has already been generated. Subsequent calls to this method return the cached instance of the existing Microsoft.Office.Tools.Excel.Workbook object. For more information, see Extending Word Documents and Excel Workbooks in VSTO Add-ins at Run Time.

Note

VSTO follows the “Automation Security” Office group policy setting when it is set to “Macros enabled” or “Disable Macros by default”. However, VSTO will always allow automation to run if the setting is set to “Use application macro security level”, regardless of the application setting. To prevent VSTO from allowing automation to run, choose the “Disable Macros by default” setting.

The workbook parameter is of type Microsoft.Office.Interop.Excel._Workbook, which is the parent interface of Microsoft.Office.Interop.Excel.Workbook. Therefore, this method can accept objects of both types: Microsoft.Office.Interop.Excel._Workbook and Microsoft.Office.Interop.Excel.Workbook. Typically, when you reference an Excel workbook, you use a Microsoft.Office.Interop.Excel.Workbook.

Applies to

GetVstoObject(_Worksheet)

Returns a Worksheet host item that extends the functionality of the specified native workbook object.

public:
 Microsoft::Office::Tools::Excel::Worksheet ^ GetVstoObject(Microsoft::Office::Interop::Excel::_Worksheet ^ worksheet);

public Microsoft.Office.Tools.Excel.Worksheet GetVstoObject (Microsoft.Office.Interop.Excel._Worksheet worksheet);

abstract member GetVstoObject : Microsoft.Office.Interop.Excel._Worksheet -> Microsoft.Office.Tools.Excel.Worksheet

Public Function GetVstoObject (worksheet As _Worksheet) As Worksheet

Parameters

worksheet: _Worksheet

The native worksheet object for which to retrieve the extended object. Although this parameter is of type _Worksheet, you typically pass a Worksheet object to this method.

Returns

Worksheet

The host item that extends the functionality of the native worksheet object.

Examples

The following code example creates a Microsoft.Office.Tools.Excel.Worksheet host item for each Microsoft.Office.Interop.Excel.Workbook object that has a host item. To use this code, run it from the ThisAddIn class in an Excel add-in project that targets the .NET Framework 4 or the .NET Framework 4.5.

void Application_WorkbookBeforeSave(
    Microsoft.Office.Interop.Excel.Workbook Wb, bool SaveAsUI,

Excel.Worksheet mySheet = (Excel.Worksheet)
    this.Application.Worksheets["Sheet1"];
if (mySheet.ListObjects.Count > 0)
{
    ListObject vstoListObject =
        Globals.Factory.GetVstoObject(mySheet.ListObjects[1]);

    vstoListObject.SetDataBinding(ds, "Product", "Name");
