Does anyone know how to save to the INI file. SaveCommandBars Description says that lpszProfileName 'Points to a null-terminated string that specifies the name of a section in the initialization file or a key in the Windows registry where state information is stored.' I would like to know what is the initialization file and how do you specify it. My app has different users and each user will have a different layout. I need to be able to specify different INI file to save and load from. But I dont see how to specify the INI file to get the data from. Documentation states to hand it the Section name of the INI file.

Can ANYONE help me with this issue. It is rather important for our app to be able to save to multiple INI files. It appears that it will only save to the WIN.INI file. Is there any other way of saving the data.

These functions decode/encode state to string. You can save this sting to INI or registry for each user. see: WritePrivateProfileString("CommandBars", "State", str, strPath);

void LoadStateFromString(CXTPCommandBars* pCommandBars, CString str, BOOL bSerializeControls)
{
int nLen = str.GetLength();
if ((nLen == 0) || (nLen % 2 != 0) )
return;

int nBytes = nLen/2;
BYTE* pData = new BYTE[nBytes];

for (int i = 0; i < nLen; i += 2)
{
(pData)[i/2] = (BYTE)
(((str[i+1] - 'A') << 4) + (str - 'A'));
}

CMemFile memFile(pData, nBytes);
CArchive ar (&memFile,CArchive::load);

try
{
  pCommandBars->SerializeBarState(ar, bSerializeControls);
}
catch (COleException* pEx)
{
  pEx->Delete ();
}
catch (CArchiveException* pEx)
{
  pEx->Delete ();
}

delete[] pData;

}

CString SaveStateToString(CXTPCommandBars* pCommandBars, BOOL bSerializeControls)
{
CMemFile memFile;
CArchive ar (&memFile,CArchive::store);

try
{
  pCommandBars->SerializeBarState(ar, bSerializeControls);
}
catch (COleException* pEx)
{
  pEx->Delete ();
}
catch (CArchiveException* pEx)
{
  pEx->Delete ();
}

ar.Flush();

DWORD nBytes = (DWORD)memFile.GetPosition();
BYTE* pData = memFile.Detach();

CString str;
LPTSTR lpsz = str.GetBufferSetLength(nBytes * 2);

// convert to string and write out
for (UINT i = 0; i < nBytes; i++)
{
lpsz[i*2] = (TCHAR)((pData & 0x0F) + 'A'); //low nibble
lpsz[i*2+1] = (TCHAR)(((pData >> 4) & 0x0F) + 'A'); //high nibble
}

ar.Close();
memFile.Close();
free(pData);

return str;
}

The LoadStateFromString and SaveStateToString functions that Oleg has given are incorrect (and don't compile). To correct them make the following changes.

In LoadStateFromString, change:
(pData)[i/2] = (BYTE)
(((str[i+1] - 'A') << 4) + (str - 'A'));
to:
(pData)[i/2] = (BYTE)
(((str[i+1] - 'A') << 4) + (str[i] - 'A'));

In SaveStateToString, change:
lpsz[i*2] = (TCHAR)((pData & 0x0F) + 'A'); //low nibble
lpsz[i*2+1] = (TCHAR)(((pData >> 4) & 0x0F) + 'A'); //high nibble
to:
lpsz[i*2] = (TCHAR)((pData[i] & 0x0F) + 'A'); //low nibble
lpsz[i*2+1] = (TCHAR)(((pData[i] >> 4) & 0x0F) + 'A'); //high nibble
