The first four links returned are sufficient. In any case, my point was that you could have very easily Googled for an answer in less time than it took to post a question here.

Doubtful, since I was not looking for code to write a service. As an aside, adding your application to the HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run key will cause it to start after a user logs in, not when Windows is booting.

Hi ALL,
I want to record Live audio and store into .wav format. Currently I can record(iff we talk directly into mike ) as well as store audio into .wav file format.

But I stucked with the quality of audio signal as after playing the recorded sound , noise is also mixing with the recording. I don't know which Filter shd I use to Filter the noise? apart from this Is it necessary to amplify the signal, so that I can record the chat/sound properly in the room also ??

Is there any other way?? Please help me out.
ThanX in advance

It sounds as though you need a primer on callbacks.

It's just a function - call it like normal:

int callbackreturn = CalBckFun(0);

Usually functions declared with the CALLBACK spec are meant to be called by the OS.

Hi,

I am using ADOs.There are about 1500 records I need to fetch from the database.The process of retrieval is taking more than 45 seconds.Is there any other approach with which I can retrieve the records fast.

Thanks in advance,

Taruni

Is the database on some other computer? What does your code look like that is fetching those records?

The database is in the same computer where my program resides.Actually I am fetching the records from the database and placing them on a grid control.

The code for fetching the records is as follows:

_ConnectionPtr pConn;
_RecordsetPtr pRecSet;
TCHAR strQuery[5000];

HRESULT hr;
CString strConn;
hr=pConn.CreateInstance(__uuidof(Connection));

if (SUCCEEDED(hr))
{

}
else
{
AfxMessageBox(_T("Failed to establish connection"));
return;
}

strConn.Format(_T("Provider=Microsoft.Jet.OleDB.4.0;Data source=%s;"),strPath);

hr=pRecSet.CreateInstance(__uuidof(Recordset));

if (SUCCEEDED(hr))
{

}
else
{
AfxMessageBox(_T("Recordset creation failed"));
return;
}
BSTR bstrconn = strConn.AllocSysString();
BSTR bstrNull = NULL;

hr = pConn->Open(bstrconn,bstrNull,bstrNull,adModeUnknown);
if(FAILED(hr))
{
AfxMessageBox(_T("Failed to open database connection"));
return;
}

try
{
VARIANT v;
VariantInit(&v);
v.vt=VT_BSTR;
_stprintf(strQuery,_T("Select * from MyDatabase"));
CString str;
CString strColName;

while(!(VARIANT_TRUE == pRecSet->EndOfFile))
{
for(int i=0;i<columnnames.getsize();i++)
{
=""
="" strcolname="ColumnNames.GetAt(i);
" v.bstrval="strColName.AllocSysString();
" fieldsptr="" fp;
="" fp="pRecSet-">Fields;
_variant_t var;
VariantInit(&var);
var= fp->GetItem(v)->GetValue();
str = var.bstrVal;
AfxMessageBox(str);
}
pRecSet->MoveNext();
}
pRecSet->Close();
pConn->Close();
}
catch()
{
.......

}
