UnhandledException 0x4bc0145c Access Violation writing location 0x

[=?Utf-8?B?c2F0aGVlc2t1bWFy?=]

In my project i have a component named PTS Engine which is developed in VC++
..Net 2003. [VC 6.0]
And it is migrated to VC++.NET 2005 version. Initially this migration
process has coded and tested in VC++ .NET 2005 Beta version. In beta version
everything is working fine. When i tryied to run in .NET 2005 full version i
am facing the following access violation Error.
"Unhandled exception at 0x4bc0145c in Engine.exe: 0xc0000005: Access
Violation writing location 0xccccccc"

The Details of the Error.
This is the code where i am calling the CreateParameter method.
/************************************************** *****
* Function to add a LONG parameter to a stored procedure (Overloading)
************************************************** ****/

void CDatabase::AddParam(CString Name, long value,BOOL IsInType)
{
//Long
try
{
_ParameterPtr pPar;
if ( IsInType )
pPar = pCom->CreateParameter(_bstr_t(Name),adInteger,adParamIn put,4,value);
else
pPar = pCom->CreateParameter(_bstr_t(Name),adInteger,adParamOu tput,4,value);
pCom->Parameters->Append(pPar);

}

catch(_com_error & e)

{

_bstr_t bstrSource(e.Source());

_bstr_t bstrDescription(e.Description());

logprintf("\nSPName: %s \nCDatabase::AddParam() \nParamName: %s \nSource :
%s \nDescription : %s
\n",m_strSPName,Name,(LPCSTR)bstrSource,(LPCSTR)bs trDescription);

CUtility::Mailer("Exception in CDatabase::AddParam(CString Name, long value,
BOOL IsInType)"); //Passed Value instead of HeaderID

throw "error";

}

catch(...)

{

CUtility::Mailer("Exception in CDatabase::AddParam(CString Name, long value,
BOOL IsInType)"); //Passed Value instead of HeaderID
logprintf("Exception CDatabase::AddParam");
}
}
/*************************************************/
The CreateParameter function is the place where i have this exception.
Similar functions are present in Database.CPP. These functions are used in
various parts of the code.
i am using the following DLL = "C:\Program Files\Common
Files\System\ADO\msado15.dll"
This application is a multi threaded console application

I need support on this:
1.How can we resolve this Access violation error
2.Whether we can use the ADO.NET to call the CreateParameter function in
..Net 2005

0xcccccccc is the pattern usually used to fill uninitialized local variables.
When you break into debugger after the exception, take a look at the values
of variables used by the code, find the one whose value is 0xcccccccc, and
check it for possibly missing initialization.
