.NET Forum / Languages / Managed C++ / August 2006quick BSTR question
How can I write a function like this: BSTR Greeting(BSTR name) { //return "Good Morning : " + name ; } In short I'm looking for a quick tutorial on using BSTR - Google is not bringing up anything consise enough (I'm not particularly interested in the history of BSTR and the differences between string types etc ... just need to get down to the "nuts and bolts" of using BSTRs) > How can I write a function like this: > [quoted text clipped - 7 lines] > the history of BSTR and the differences between string types etc ... > just need to get down to the "nuts and bolts" of using BSTRs) You can use SysAllocString to allocate BSTRs You have to use SysFreeString to deallocate them afterwards. If you google around for tutorials that mention SysAllocString, you should find a number of articles that tell you how to use BSTRs  SignatureKind regards, Bruno. bruno_nos_pam_van_dooren@hotmail.com Remove only "_nos_pam" > How can I write a function like this: > [quoted text clipped - 7 lines] > the history of BSTR and the differences between string types etc ... > just need to get down to the "nuts and bolts" of using BSTRs) Well the thing is that it's easier for you to understand BSTR if you understand the "differences between string types etc." But search for _bstr_t, it makes using BSTR *that* much easier. Of course this being C++ you can't expect it to be as simple as VB, but close enough :)
