Returning an array of BSTR from the COM Component

[Raj Prathap]

Hi, I have a method which has to return the array of BSTRs. I'm giving the method here, please let me know if I'm doing anything wrong. HRESULT Login([in] BSTR UserName, [in] BSTR Password, int maxUsrCnt , [out]int *UsrCnt, [out, length_is(,*UsrCnt), size_is(,maxUsrCnt)] BSTR *LoggedUsers); the size of the array to be returned is not known at the time of calling. When I use this method, the first string is coming properly, but other strings are not coming. Please suggest an answer. Regards, Raja Pratap

I never need to output the array back yet. I only guess that the last parameter should be declared as "BSTR **LoggedUsers". It is because: to output single string, should use "BSTR*". To output an array of strings, logically it should be "BSTR**". If my guess is correct, let me know. :-)

I Tried with BSTR**, could not succeed. Only first string comes, since the marshaller considers only the first string, since length is not mentioned. I got a hint from one of CP members to use SAFEARRAY(BSTR)* that worked fine.
