CString GetBuffer

[nss]

I'm reading MSDN but am not really sure whats happening:

    dbName = "";
    size=128;
LPSTR psz = dbName.GetBuffer(size);

SO does this mean that I've fixed things so that I can copy somethig less than 128 bytes into dbName? SO if I just did dbName = "aaaaaaaaaaaaaaaaa" directly who takes care of the fact that dbName was zero bytes long ("" emoty) before? When is one method better than another? Or --- when it is necessary to do the GetBuffer strategy?

Check out my C++ string classes[^] article where I cover CString in detail. But to summarize, dbName.GetBuffer(128) makes sure that the dbName buffer is at least 128 characters long (allocating more space for you, if necessary) and returns a non-const pointer to the buffer. You can then use that pointer as if it were a normal C-style string. When you call any other CString methods (such as the = operator), that pointer may become invalid because some CString methods delete/reallocate the buffer. nss wrote: SO if I just did dbName = "aaaaaaaaaaaaaaaaa" directly who takes care of the fact that dbName was zero bytes long before? CString manages its own memory (except for when you explicitly take control of the memory with GetBuffer()). --Mike-- I'm bored...
