TIERFBClient.LockFrameBuffer
Declaration
procedure LockFrameBuffer;
Description
Locks frame buffer and cursor bitmap preventing writing operations.
This method can freeze the message handler thread so ensure you call
UnlockFrameBuffer and to maintain frame buffer locked for less time as possible.
Applications could prevent frame buffer updates just setting
Suspended = true, which does not freeze the connection.
rfb.LockFrameBuffer;
try
ImageEnMView1.SetImage( imageIndex, rfb.FrameBuffer );
finally
rfb.UnlockFrameBuffer;
end;
