You may use CString::Format for this purpose.

For s = 1 To 10
rec(s) = " #" & CStr(rs2(0)) & CStr(rs2(1))
msg4 = msg4 & rec(s)
rs2.MoveNext
Next s
how can i convert this in VC++?

Next s
where rs is a recordset which has only two columns..

What does, rs2(0),rs2(2) would return ?
Say its returning int.
In that case,
you use.
CString sTemp;
sTemp.Format(_T("%d%d"),rs2(0),rs2(1));

There's not a direct replacement for it because CStr() returns a different value depending on the type of value sent to it. For example, it might return True/False if the value is Boolean, or a short date if the value is a Date.

Hello everybody,
Is there any possiblity to declare a variable as a Variant and a Variant array?
for example in VB, we can declare
Dim rec(80) As Variant //array
Dim msg As Variant
Is there any possibility to declare like this Visual C++?
Likewise in VB,
'msg' which holds some variant value and I can display it in text box.
Text1.Text = msg3
How can I display the variant value in edit box?
Please reply me.. thanks in advance.

SAFEARRAY and VARIANT are its replacement in VC++.

I'm not sure, but in VB variants are used for representing array.
So, its char array in terms of C++.
So you can use char array or CStringArray as its VC eqvivalent.

Dear All
I have to monitor a printer, and for that I have to use FindFirstPrinterChangeNotification and FindNextPrinterChangeNotification APIs. For this I have written the code, which is below. Some problems that i am facing with this code are also stated below (after the code). It will be great you can shed some light on the issues I am facing. It will be of great help.

I dumped the notification data in a file, and had the following
observations:
1. I never received any Status notification for any type of Print job,
i.e be it in EMF format or RAW format. In case of Status String, the
notification was there, but the pBuf was empty. So, how do we receive the status info?
2. In case of print job with EMF data type, the Total Pages and Printed
pages data was received correctly. Same case for Total Bytes and
Printed Bytes.
3. In case of print job with RAW format, Total pages was received with
correct values, but Printed Pages was always recieved with the value 0.
Total Bytes was OK, but at the end of the print job, the Total Bytes
and Printed Bytes were different, the latter being lesser then former.
So, it doesn't help in determining that whether a print job is finished
or not.
Thanks in advance.

Use CWaitCursor class.
e.g
void CMyClass::foo()
{
CWaitCursor cursor;
cursor.Restore();
}

Ignore this answer. It was wrong!
Sorry.
I give myself a 1.

Restore is meant for restoring wait cursor, if its been changed.
Sometime , during lengthy operations, it get changed to some other cursor.
This function restores it back to wait cursor. I think you misinterpreted its functionality.

 , Original cursor gets restored in this case.

that's a 'modeless' cancel dialog. there are examples on CodeProject (look in the MFC / Dialog section).

Hello,
thanks very much for answer,
hmm, i can make an *.gif image, such as e.g. myhour.gif(animate gif) and

I have an image of a classroom. I want to get the position(coordinate) of every desk in it(the color of the desk is different from that of the background).
Are there any good and simple arithmetics to deal with this problem? It doesn't have to be very precise.
Thanks!
