MapiLogonEx function failing

I am using the MAPI IProfAdmin interface for creating the profile .I can see that profile is completely created in registry also .
After that i want to logon using that mapi profile .
For that i am using the MAPILogonEx function without MAPI_LOGON_UI parameter as i dont want any UI there .
At this time logon is failing .I was thinking that profile is not created so what i did ,i used MAPI_LOGON_UI parameter and specified that mapi profile name also .

MAPILogonEx(0,lpszProfile,  NULL,    MAPI_EXTENDED | MAPI_NEW_SESSION | MAPI_UNICODE | MAPI_LOGON_UI, &m_mapiSession)

Now its prompting as invalid name .Then clicking on ok ,it displayed a drop down with a list of existing mapi profile name .I can see my mapi profile there also .I means mapi profile exist but the way i am trying to access is not correct .

Need help on the same .

Here is the code :-

// programmatically create a profile. No UI is displayed.
