Start with the following.

// utilise ado 2.6
#import "msado15.dll" named_guids
// full path is required - shouldn't be too hard to find

This will allow you to access the ADO objects utilising standard COM.

BTW, the typical path is

C:\Program Files\Common Files\System\Ado

Sorry, but I don't even have a C++ compiler installed at the moment.

Do you want to use ODBC or ADO?

For pure ODBC level calls,
Use SQLAllocHandle to get an environment pointer. Then, use SQLSetEnvAttr to set the ODBC version on the environment. Use SQLAllocHandle to allocate the database handle, SQLConnect to create a DB connection.

Then create a STMT handle using SQLAllocHandle. SQLPrepare prepares the STMT handle with whatever query you want to execute. Then, SQLExecute exeutes that query.

You will get the documentation for the APIs in MSDN

I though ADO uses ODBC connection to make a call. Then maybe it is different in c++. WHat about ADO?

// You can get the clsid using #import "msado15.dll" named_guids
HRESULT hr = spADOConnection.CoCreateInstance(CLSID_CADOConnection);

hr = spADOConnection->put_Mode(adModeReadWrite);
hr = spADOConnection->put_CommandTimeout(1000);

//Create your connection string
hr = spADOConnection->Open(cbstrConnectionString, NULL, NULL, adConnectUnspecified);

//Set your query in pwszQuery
hr = spADOConnection->Execute(CComBSTR(pwszQuery), &svarRecordsAffected, adCmdText, &spADORecordSet);

Well, I certainly do have problems with leaving the question unanswered. prokni has said that he/she cannot test the answer suggested. So, I would expect that he/she would post the problems that were encountered while testing the suggested solution. Without any intimations from both sides, how can one expect the appropriate solution to be arrived at?

I agree that simply accepting the answer would prove wrong in that it would be misleading in the future for others. But, I am suprised that the need to arrive at the solution is driven by the needs of the enterprise and not by personal will. I strongly object to the point that the question is now invalid because the requirements at the questioner's end have changed. Rest is up to the moderator.

I am not agree with this part of your comment

This is the reality in our life. Personal will does not matter at all!!
I agree with the rest.

I am open for any suggestion from moderator. I am willing to give the complete points to Madz in anyway that is possible without misleading others.

Thanks
