COM Widestring Value Issue
Question:
I need to do myobject.myproperty= "hello as a wide string"lpwstr is used once in the doc. Is that a winbatch limitation or is there a turn around?
Answer:
All strings passed to COM objects and methods are converted to Unicode stings by WinBatch and they have been since WinBatch first added OLE support. If you see object documentation that references LPWSTR, it is possibly referring to dual interfaces. Dual interface objects can be early bound using a byte compiled language like c/c++ or VB or they can be late bound using the Dispatch interface. WB is a scripting language like VBS or Perl and supports late binding. If you have an object with a dual interface or just the Dispatch interface, LPWSTRs are dealt with automagically. However, if you have an object that only supports early binding, you can not use it directly in WB or VBS or almost any other scripting language so support for LPWSTRs is a non-issue.Article ID: W17088
