UltraExplorerBar - SaveAsBinary - Serialization Error!
posted

Below is the exact code snippet from your help documentation. I use the same to save the layout to a file and reload it back from the file. It always throws a serialization error everytime the save is called.

// Create a file stream to which the layout will be serialized

System.IO.FileStream fileStream = new System.IO.FileStream(@"C:\Layout.bin",

System.IO.FileMode.OpenOrCreate);

// Save the layout to the file that was just created

explorer.SaveAsBinary(fileStream);

// Close the file stream

fileStream.Close();

Exception:

 explorer.SaveAsBinary(fileStream) 'explorer.SaveAsBinary(fileStream)' threw an exception of type 'System.ApplicationException' void {System.ApplicationException}

  base {"Serialization error!"} System.Exception {System.ApplicationException}
  Inner Exception:  "Object reference not set to an instance of an object."

  Stack Trace:

Any help will be greatly appreciated.

    This is a bug; you should report it so that you are notified when the fix becomes available. Note tnat this bug should only manifest itself when the ToolTipText property is explicitly set to null; if you set it to string.Empty instead, that will prevent the exception from being thrown.
