BSTR to const char[]

[AssemblySoft]

I've created a get / put property inside an activeX control. I know the functionality is working ok because i've tested it with script What i now need to do is copy the BSTR into a char* or c style array. I've tried: char str[MAX_PATH]; CComBSTR m_bstrString; put: ATLTRACE(_T("String assigned to: %ls\n"),newVal); m_bstrFileString = newVal; //assign btr to CComBSTR //do conversion BSTR var = m_bstrString.Copy(); strcat(str,(LPCTSTR)var); It only seems to be copying the first char? Please help :doh:

I'm sure this will help: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_atl_String_Conversion_Macros.asp[^]

The following line has undefined variable m_bstrFileString (could be typo) m_bstrFileString = newVal; //assign btr to CComBSTR Note : W2A macros has limitation, can not be used in loop. It can convert max 500KB of chars One more soln would be using _bstr_t class.. For Ex: char str[MAX_PATH]; _bstr_t str1(newVal); strcpy(str,(char *)str1); Sandeep Naik
