Hi,
while I am trying to retrieve the data from the database, where ever there is blank space (empty) in the correspoding column ,I am getting junk values.
This is my code.
VARIANT v;
v.vt=VT_BSTR;
CString str;
str = " ";
while(!(VARIANT_TRUE == pRecSet->EndOfFile))
{
str = pRecSet->GetCollect(v).bstrVal; .
//There is some junk data in str;
.
.
}
Should I do any other initialization or conversion? I have even tried using "NULL" but failed.
Thanks in advance.

Use VariantInit to initialize the variant. Your code will be like this,
VARIANT v;
VariantInit(&v);
v.vt=VT_BSTR;
Check value of vt after using it in function. In other words, are you sure function in populates vt with VT_BSTR.

Hi Prasad,
Thank you for your immediate response.
VariantInit(&v);
I already tried this and but no use.

What about my second point ? Does vt is initiailized to VT_BSTR , After using it as parameter ?
If yes, Do you see junk values in bstrVal of variant argument ?
|
|
|
|
|
Yes Prasad ..there are is still junk data in bstarVal.
My code is as follows :
VARIANT v;
VariantInit(&v);
v.vt=VT_BSTR;
CString str;
str = " ";
while(!(VARIANT_TRUE == pRecSet->EndOfFile))
{
str = pRecSet->GetCollect(v).bstrVal;
.
.
}

Which class does GetCollect belongs to ?

How it is declared ? If it is out parameter, you are not using its value further. Instead you are using its return value.

I am receiving some voice file from the network i am storing it into a buuffer using Receive() function and that is a sound file which is converted into a wave format. I am trying to play that buffer here in the recieving side using
PlaySound(Buff,NULL,SND_MEMORY|SND_ASYNC)
but i could not here anything after playing.
But if i am saving that buffer into a .wav file and play it by a doubleclick on the file it plays the sound. Where might be the problem?
Thanks in advance!

I assume, Buff contains sound bytes you recevied. But what MSDN suggests PlaySound has first parameter which points to image file. In other words,its should be stored on disk.

I found
A sound event's file is loaded in RAM. The parameter specified by pszSound must point to an image of a sound in memory.
in the MSDN. I guess that mean it should be stored in the RAM rather than disk.
That's what i did (Buff.
Is't it?

Agree, but in your case it is pointing to buffer rather than file name.
|
|
|
|
|
What happens if you do this:
PlaySound(Buff,NULL,SND_MEMORY|SND_SYNC)
Are you sure Buff is valid for the duration of playback?
|
|
|
|
|
Are you sure Buff is valid? did you trace when it filled?

I'm working on a project and was wondering if there is a class like C#'s MailMessage (but for C++, I'm using visual studio 2003) that will allow me to write a program that will automatically send me an error log every month or so. I'm kind of new to the C++ world and would appreciate any help. Thanks!!

There's nothing built into the language, no. MAPI is the easiest way to go.

If you need simple email alert notifications from a service and don't plan on implementing more than the basics, you can easily derive a basic mail client from RFC 2821 & 2822. RFC 2822 is probably the simpler and the more helpful of the two for implementing simple alerts.
Using the winsock2 api, just write a class that performs the steps you use when testing an SMTP server with a telnet session.

need to make a dsn less connection to a file whose path is known. my present code connects to dsn..
m_retcode = SQLAllocHandle(SQL_HANDLE_DBC, m_henv, &m_hdbc);
m_retcode = SQLDriverConnect(m_hdbc, NULL, (unsigned char *)pConString, SQL_NTS, NULL, 0, &m_constrout, SQL_DRIVER_NOPROMPT);
what should the parameters be now?
