Agreed. But sadly, there are many companies that still do all their development in VS6.

If the OP hasn't already done so, he might want to download the fixed STL from Dinkumware's site (they are the ones that wrote the version that ships with VS). There were several bugs that were fixed, not sure if this might be one of them.

Unfortunately, I have to stick to VS6. It's really bad that the behavior might come from bugs in the STL Frown | :(

Can I simply replace the problematic STL classes? If so, can you provide the Link to the Dinkumware's site?

Thank you for you discussion. That brought some light into the dark. I already started thinking that I'm getting to old for understanding C++ Wink | ;)

Therefore I like your slogan, Zac!

I think Microsoft has a link in MSDN for a service pack download that does it. But here is Dinkumware's site: http://www.dinkumware.com/.

Marcus,

There is simply quite a bit of valid code that the VS6 compiler is unable to compile. This in turn limits the quality of the STL that can be provided for it. At the end of the day, it's an 8 year old compiler that was written before the C++ standard was finalized IIRC.

Can you please make it a little more clear what exactly you did in OnInitDialog() ?

BOOL CCmpDataEntryDlg::OnInitDialog() //CmpDataEntryDlg is my propertysheet
{
m_SpinDropRate.SetRange(5,19); //to set the range for spin control

m_pSet = new CCampaignSet(); //this is my recordset
if(!m_pSet->IsOpen())
{
CWaitCursor wait;
m_pSet->Open();

}

CPropertyPage::OnInitDialog();
UpdateData(FALSE);

return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}

As I know:

1) there is no idea to get margin info of a printer.
2) margins can not be adjusted by VC applications.

it is very strange that same printer may have different margins if printed by different PCs.

hi,

TO set Margings mean how to calculate the space it top,left,bottom,right while priting. which is done in VC++ application.

I want to Calcualte the Margin in VC++ only not in Priter.

You understand.

Thanks

uday.

The WM_COMMAND message is sent when the user selects a command item from a menu, when a control sends a notification message to its parent window, or when an accelerator keystroke is translated.

And here's an extension to the above post
From DOCS
wParam
The high-order word specifies the notification code if the message is from a control. If the message is from an accelerator, this value is 1. If the message is from a menu, this value is zero.
The low-order word specifies the identifier of the menu item, control, or accelerator.

lParam
Handle to the control sending the message if the message is from a control. Otherwise, this parameter is NULL.

Somethings seem HARD to do, until we know how to do them.

Did you saw MSDN.
From the MSDN
"This message is sent when the user selects a command item from a menu, when a control sends a message to its parent window, or when an accelerator keystroke is translated."

Hi toxcct,
its not problem do you konw why?i think he is lucky because he and you and programers are here and
he find his answer when he has a question he write his question here
whatever this question is clear or not clear but when i start to learn VC i dont have any resource
(teacher or website or anything) except MSDN

actually, it's always easy to ask valuable people who know the answer to your question. but hey, the minimum he can do he search a bit by itself, googling, searching the msdn... and only then, ask the forum. people sometimes seems so lazy Frown | :(

Except he obviously was too lazy because simply typing WM_COMMAND (no need even for site:msdn.microsoft.com) into google brings up the relevant information.
