Visual Basic

C++/CLI

'Declaration
 
Public Overridable Sub SaveStillDIB( _
   ByVal fileName As String, _
   ByVal timeOut As Integer _
)

'Usage
 
Dim instance As PlayCtrl
Dim fileName As String
Dim timeOut As Integer
 
instance.SaveStillDIB(fileName, timeOut)

public virtual void SaveStillDIB( 
   string fileName,
   int timeOut
)

public:
virtual void SaveStillDIB( 
   String^ fileName,
   int timeOut
)

Parameters

fileName: A string that represents the name to use when saving the snapshot.
timeOut: The timeout period, in milliseconds. This method will fail if it was not able to take a DIB in the specified time. Use -1 to wait indefinitely until a DIB is snapped.

Saves a snapshot from the running stream to a file. The file is saved as a DIB using the specified filename and timeout period. This method blocks (does not return) until the timeout occurs or the DIB is snapped.
