  Returns

A long which indicates the success/failure of the operation. Zero (0) is returned if successful, otherwise a non-zero value is returned. If an error occurs you can use this return value as the argument for GetErrorText in order to retrieve a relevant text error message, or alternatively you can rem out the "On Error Resume Next" statement and observe the thrown exception for a description of the error.

Remarks

You can use this as a test method to see if the control is actually producing a jpeg.

You can also use this method in a VB (Visual Basic) application and then call VB's LoadPicture method to assign the jpeg to a Picture Box or Image control.
