Example

Demonstrate using a workbook set in a thread safe manner when accessing the SpreadsheetGear API many times.
C#Copy Code
void DoSomeThreadSafeWorkQuickly(IWorkbookSet workbookSet) 
        { 
            // Interrupt background calculation if necessary, acquire an 
            // exclusive lock on the workbook set and suspend events and 
            // painting. 
            workbookSet.BeginUpdate(); 
  
            try { 
                // Do a lot of work... 
            } 
            finally { 
                // Release the lock on the workbook set, start background 
                // calculation if appropriate and repaint controls. 
                workbookSet.EndUpdate();

Visual BasicCopy Code
Sub DoSomeThreadSafeWorkQuickly(ByVal workbookSet As IWorkbookSet)
            ' Interrupt background calculation if necessary, acquire an
            ' exclusive lock on the workbook set and suspend events and
            ' painting.
            workbookSet.BeginUpdate()

            Try
                ' Do a lot of work...
            Finally
                ' Release the lock on the workbook set, start background
                ' calculation if appropriate and repaint controls.
                workbookSet.EndUpdate()
            End Try
        End Sub 'DoSomeThreadSafeWork

Remarks

This method is thread safe.

EndUpdate releases the lock which was acquired by BeginUpdate by calling GetLock.

See GetLock and ReleaseLock for more information about acquiring and releasing locks and the effect this has on background calculation.
