imapi staging image for record iz on CD WINxp

[cagi]

Hi to all, this is my first post here so I'm hoping you can help me. Now I'm writing a app which, among all other things need to record some data to CD. I'm using IMAPI v1 and here is the problem: i cant create an staging image, this is the part of my code:

...
IStorage* pStorage = NULL;
IStream* pStream;
int i=0;
StgCreateDocfile( NULL, STGM_DIRECT|STGM_CREATE|STGM_READWRITE|STGM_SHARE_EXCLUSIVE, NULL, &pStorage);
 
CFile files[32];
 
//filenames is CStringList which is populated by users choice of files they want to record on CD
POSITION pos = filenames.GetHeadPosition();
while(pos != NULL)
{
CString strFilePath=filenames.GetNext(pos);
 
int nSize = 0;
CFileException e;
 
if (filesIdea.Open(strFilePath,CFile::modeRead|CFile::typeBinary,&e))
{
LPWSTR lpszW = new WCHAR[255];
LPTSTR lpStr = strFilePath.GetBuffer( strFilePath.GetLength() );
int nLen = MultiByteToWideChar(CP_ACP, 0,lpStr, -1, NULL, NULL);
int code = MultiByteToWideChar(CP_ACP, 0, strFilePath, -1, pszW,nLen);
if(!code)
{
CString tmp = _T("'MultiByteToWideChar' returns NULL!");
DWORD err = GetLastError();
DisplayErrorString(tmp,err);
if (lpszW)
delete [] lpszW;
filesIdea.Close();
pDiscMaster->ClearFormatContent();
return FALSE;
}
 
HRESULT res;
if( (res = pStorage->CreateStream( lpszW, STGM_DIRECT|STGM_CREATE|STGM_READWRITE|STGM_SHARE_EXCLUSIVE|STGM_FAILIFTHERE, 0, 0, &pStream) ) != S_OK )
{!!!HERE IT'S CRACKS SAYING "Invalid value for pwcsName." (lpszW???)
ShowHRError(res);
if (lpszW)
delete [] lpszW;
filesIdea.Close();
pDiscMaster->ClearFormatContent();
return FALSE;
}
nSize = files[i].GetLength();
BYTE *pBuffer = new BYTE[nSize];
if (files[i].Read(pBuffer,nSize) > 0)
{
pStream->Write(pBuffer,nSize,NULL);
pStream->Release();
}
files[i].Close();
delete[] pBuffer;
}
 
...
 

As I put it my code breaks in line 37.
I'm trying to find code example which works?? Or someone who can tell me where I did wrong??Why can't I create stream, what is wrong with lpszW?
THX to all!

Per Microsoft docs lpszW:

must not exceed 31 characters in length (not including the string terminator). The 000 through 01f characters, serving as the first character of the stream/storage name, are reserved for use by OLE. This is a compound file restriction, not a structured storage restriction.

Does your lpszW fconform to this?

I'm aweare of that!

Can I burn both directories and files?
