Hi,
I want to attach one of the menu resource to one of my child frame but i am not able to do so. I am putting code below, the following code is written in the App class and will execute on the click of a button:

CQSMChildFrame *pQSMMiniFrame = new CQSMChildFrame ;
if(!pQSMMiniFrame->LoadFrame(IDR_QSM,WS_OVERLAPPEDWINDOW | WS_CHILD, m_pMainWnd))
{
AfxMessageBox("Could not load QSM Frame");
return;
}

HMENU hMenu = NULL;
LPTSTR lpszMenuName = MAKEINTRESOURCE(IDR_QSM1);
if (lpszMenuName != NULL)
{
HINSTANCE hInst = AfxFindResourceHandle(lpszMenuName, RT_MENU);
if ((hMenu = ::LoadMenu(hInst, lpszMenuName)) == NULL)
{
AfxMessageBox("Warning: failed to load menu for CFrameWnd.\n");
return;
}
}

CMenu menu;
menu.Attach(hMenu);
BOOL y = pQSMMiniFrame->SetMenu(&menu);

pQSMMiniFrame->BringWindowToTop();
pQSMMiniFrame->SetOwner(m_pMainWnd);
pQSMMiniFrame->ShowWindow(SW_SHOW);
pQSMMiniFrame->UpdateWindow();

where CQSMChildFrame is derived from CMDIChildWnd and the application is an MDI based application.

When i debug the application, if fails at the SetMenu() line and returning false.

Even i tried loading and setting menu in the OnCreateClient() handler of CQSMChildFrame but not successful there also.

Please help me what i am doing wrong?

Thanks,
Amit

Round dialog drawing question

Hello all,

I have a dialog that has the style - popup and none (for border)

I've created a round edges for the that dialog using the following code:

CRect rc;
GetClientRect(rc);
CRgn rgn;
rgn.CreateRoundRectRgn(rc.left,
		       rc.top,
		       rc.right,
		       rc.bottom,
		       15,
		       15);
SetWindowRgn(rgn,TRUE);

now i try to draw a border for this border-free dialog, using the following code:

void CMyDlg::OnPaint() 
{
   CClientDC dc(this);
   CPen pen(PS_SOLID,2,RGB(0,0,0));
   CPen* pOldPen = (CPen*)::SelectObject(dc.m_hDC,pen);
   CRect rc;
   GetClientRect(rc);
   dc.MoveTo(1,1);
   dc.LineTo(rc.Width()-1,1);
   dc.MoveTo(rc.Width()-1,1);
   dc.LineTo(rc.Width()-1,rc.Height()-1);
   dc.MoveTo(rc.Width()-1,rc.Height()-1);
   dc.LineTo(1,rc.Height()-1);
   dc.MoveTo(1,rc.Height()-1);
   dc.LineTo(1,1); 

   ::SelectObject(pDC->m_hDC,pOldPen);
}

the trouble is , since i've create the round edges, there is no drawing on them, i tried to use the dc.Arc method, but i don't know how to calculate the exact arc....

can any1 show me the proper code, so the dialog rounding would have a drawn border as well?

thanks in advanced

CRect rc;<br />
GetClientRect(rc);<br />
<br />
rc.Deflate(3,3);<br />
<br />
CDC::RoundRect(rc, CPoint(15,15));<br />

Just make sure you have an empty fill-brush and this should do the job more or less.

create it in the form of .hlp file and for the VC++ application save this help file in the VC++ Application's help file path. You have to change value of helpfilename variable for your CWinApp derived class. Rose | [Rose]

Pdh API - CPU Counter returns 99

Im querying the counter
"\\Processor(_Total)\\% Processor Time" using Pdh functions. But during the first query (PdhCollectQueryData, and PdhCollectQueryData) I am getting the value fmtValue.longValue (Query result) as 99 always. But during the consecutive calls it returns the appropriate CPU usage values. I susected this as the CPU used during the call - But windows Taskmanager doesnt show that (99). Can someone explain this - Thks in advance! Wilson

Im expecting the CPU usage % on my machine, which is not 99% actually (verified using TaskManager). But it returns 99 only in the first call. It returns the actual CPU usage (normallu 1-10 on my machine) in the consecutinve calls.

you can use edit->SetWindowLong
and use style as ES_NUMBER

Which limits the control to numbers only.

You can go through my article Numeric Edit Control[^] to find an answer to your problem. You can also download the complete source code with the article and use it as it is to save your time (of course only if you are working with MFC).

Does the SMTP server exist that you are referencing? If so, is it using port 25 for the SMTP service?

I would be inclined to ask my ISP about their SMTP server. If you are doing this from within a company, then ask the network administrator.

must port number be 25 for SMTP?

No. There are 2¹⁶-1 ports, but port 25 is the most common.

If your program is using port 6400, that means that the SMTP server must also be using port 6400. If the ports do not match, your program will not work.
