Remarks

 
Once a Design is created, using the Open method allows for an existing design to be loaded. Any data currently held in the design pointer will be lost and the contents of the design file will be brought into memory.
The following parameters are required for this call:
 
  • BSTR bstrFilename
– The name of the eXpress design to open.
  • long nLimitFlags
– Provides ability to load only portions of design. Should be set to 0xFFFF for all data.
  • BOOL bReadOnly
– Causes the design to be opened in read-only mode.
