Hi all,
i have the following xml file:
<?xml version="1.0"?>
<rt name="Remote ">
<Connection connect= "connectval" ipaddress = "ip_addresss" Port = "port_number"/>
</rt>
I want to get the value of variable connect and store it using selectsinglenode function.
how can i accomplish the above.

What exactly is the problem?

I am using SelectSinglenode in the following way and the code is always aborting:
IXMLDOMNodePtr pChild;
IXMLDOMNode **resultnode=NULL;
HRESULT pChild = pParent->selectSingleNode(_T("rtcs//Connection::connect"),resultnode);
i think i am not able to give the right first parameter of selectsinglenode function.
Regards

if pParent is a IXMLDOMNodePtr, then you have to do:
pChild = pParent->selectSingleNode(_T("rtcs//Connection::connect"));
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Could that be:
"//Connection/@connect"
describing any <connection> tags having a "connect" attribute?
I am not an XPATH-Guru, though.
Failure is not an option - it's built right in.

In MFC SDI,How to write D3D code?
I had wroteen some code about D3D in MFC SDI project.
But I have a problem that when I resisze the view, the model will resize.
I had reccomputed the projective matrix by the view size (when I resize the View).
I had tried to modify the projective matrix and viewport.
But it seems to be error.
HRESULT hr;
hr=m_pD3DDevice->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_ARGB(255,0,0,0), 1.0f, 0);
m_ViewClientSize.cx=cx;
m_ViewClientSize.cy=cy;
D3DXMATRIX proj;
D3DXMatrixPerspectiveFovLH(
&proj,
D3DX_PI * 0.5f, // 90 - degree
(float)m_ViewClientSize.cx / (float)m_ViewClientSize.cy,
1.0f,
1000.0f);
if (m_pD3DDevice)
m_pD3DDevice->SetTransform(D3DTS_PROJECTION, &proj);
D3DVIEWPORT9 ViewPort;
m_pD3DDevice->GetViewport(&ViewPort);
ViewPort.Width=m_ViewClientSize.cx;
ViewPort.Height=m_ViewClientSize.cy;
if (m_pD3DDevice)
m_pD3DDevice->SetViewport(&ViewPort);

Hi,
how can i check, given a file name, if the file has been 'locked' by any process... either for reading, writing or both?
Thanks...

Can you open the file exclusively?

Actually, I want to check whether a file is locked by *any process*, be it my own app or any other process...
I'm aware of file locking functions when we open a file ourselves... but what about the files that are locked by some other app..?

If a file is open by another process, and your process tried to open the file exclusively, it would fail.

I try setting the top index of the listbox to be anything, and it stays at zero for some odd reason. This listbox has an image under it in order to allow mouse over event. Each item's height is 13.
void __fastcall TfmMain1::lbTitlesMouseMove(TObject *Sender,
TShiftState Shift, int X, int Y)
{
int position = (ScrollBox1->VertScrollBar->Position)/13;
Label1->Caption = position;
lbVisible->TopIndex = 1;
lbTitles->TopIndex = position;
}

Your OnIdle never gets called?
Have you seen this? OnIdle Member Function[^]

Hello, now i read that document also but i am still unable to gets called "onIdle" method can you tell what i have to do for that.
also i have another application in which, onIdle method gets called at the time of start application and end application i also i want that
please tell me where i am wrong......

If your OnIdle() override isn't getting called then I'd guess that your app is dialog based and
your main dialog is modal.
In that case, you need to use the undocumented WM_KICKIDLE message:
afx_msg LRESULT OnKickIdle(WPARAM wp, LPARAM lp);
#include <afxpriv.h>
ON_MESSAGE(WM_KICKIDLE,&CMyMainDlg::OnKickIdle)
LRESULT CMyMainDlg::OnKickIdle(WPARAM wParam, LPARAM lParam)
{
return 0;
}

Hi,
Can anybody tell me how to get the list of usb devices which are connected to the system? Is there any Win32 API?
How will i know the USB version and speed of my system?
Regards,
Mayuresh

The short answer is, not easily. You must be the 20th person to post this question or one very close to it in the last couple of months. I have code that will do this but it is part of a commercial application so I can't simply post it 
I looks like I'll finally have to give in and write an article describing it as so many people seem to want to know. It means putting other things on hold but watch this space.
Nothing is exactly what it seems but everything with seems can be unpicked.

Yes...Matthew, you should have to write an article which describes it and definately it will help others.
But at this momonet, can u atleast tell me the Win32 APIs, because I am relally stuck at this point? I used SetupDiGetClassDevs,SetupDiEnumDeviceInfo and SetupDiGetDeviceRegistryProperty APIs. but it gives all the devices. I want only USB devices connected to the system?
Please help me out...!

OK It sounds like you're most of the way there. You'll probably have something similar to this example this example[^] by now.
You need the GUID for USB devices, GUID_DEVCLASS_USB which lives in devguid.h which is part of the DDK. For maximum compatibility I used the one from \inc\w2k in the 3790.1803 version of the DDK which is available here[^]. You may be able to get this definition from the SDK headers these days, I'm not sure. If all you want is the USB devices of whatever type then that should be enough. If you want devices of a specific type e.g. disks then a call like this might be needed.
<br />
hIntDevInfo = SetupDiGetClassDevs (<br />
(LPGUID)&DiskClassGuid,<br />
NULL,
NULL,
(DIGCF_PRESENT | DIGCF_INTERFACEDEVICE
));<br />
The device type GUIDS like DiskClassGuid come out of winioctl.h
If you get a neat solution working I suggest you write that article yourself. You'll be a CP hero in no time

Hi,
When a user activates a window (in the program I am writing) I was wondering what message it sends and what function I can use to add some additional functionality when this happens.
Thanks for any tips.
