There are different ways to do this
you can either use EnumWindows to enumerate all windows and match the class name.
To see if Internet Explorer is running use

HWND hExplorer = ::FindWindow("IEFrame", NULL); 
if (!hExplorer) 
{
	hExplorer = ::FindWindow("CabinetWClass", NULL); 
}

If you want to get the URL then you can see

GetDiskFreeSpaceEX API Problem

hi,

I need to get the actual amount of free space available on the hard disc. I am using GetDiskFreeSpaceEX API to get the amount of free space. The problem is that the amount of free space returned is different at different times.

Can any one tell me the reason why the value is different?
Also, Is there any other API which is much more reliable than GetdiskFreeSpaceEx?

Thank u in advance ,

regards,
nisha

I think, it is due to OverFlow. Check once.

Using FindFirstFile and FindNextFile methods.

I have to store a DateTime in the registry in binary key. I think i can use the DateTime.m_dt variable which a double to store the value of the datetime. But I don't know how to convert it to binary like in Managed where we have the BitConverter.GetBytes(double). I need this urgently.

Hi, you can use a union with a buffer of 8 bytes and your DateTime.m_dt variable, like in the following example:

<br />
typedef union DateTimeConversionTag<br />
{<br />
	char m_buffer[8];<br />
	double m_datetime;<br />
} DateTimeConversion;<br />

How can I use CScrollView in a dialog

puresnow22-Mar-06 22:24

22-Mar-06 22:24

I want to create a CScrollView in a dialogbased project.So i follow thsese steps :
1.createa a dialogbased project named MyDlg.
2.drag a CStatic control to this dialog,its ID is IDC_STATIC_VIEW
3.Create a new class named CMyView and its base class is CScrollView
4.Add a member function CreateView,include "MyView.h",Add a member variant
CMyView *pView;
we realize it like this:
VOID CViewInDlgDlg::CreateView()
{
CRect rect;
CWnd* pWnd=GetDlgItem(IDC_STATIC_VIEW);
pWnd->GetWindowRect(&rect);
ScreenToClient(&rect);

CCreateContext cx;
cx.m_pNewViewClass=RUNTIME_CLASS(CMyView);
cx.m_pCurrentDoc=new CDocument();

CFrameWnd* pfWnd=(CFrameWnd*)this;
CWnd* pView=pfWnd->CreateView(&cx);
pView->MoveWindow(&rect);
}
When I run this program, i found there was a ASSERT error at line 134 in viewsctrl.cpp.I correct it by overriding the function OnPrepareDC,I modified like this:
CView::OnPrepareDc(..)
Then no error ocurred.
I try to test if it can work,so i add a button in this dialog.Then I wrote this in its OnButton1 function,I wrote this:
void CMyDialog::OnButten1()
{
CDC *pDC=pView->GetDC();
pDC->TextOut(10,100,"hello");
}
Click this button it crashed.
The error happened in this line:
{ ASSERT(::IsWindow(m_hWnd)); return CDC::FromHandle(::GetDC(m_hWnd)); }
I have no idea now,someone can help me correct this error?
PS:If MyView Class is based on CView,then this error cannot be found.
As English is not my native language,i hope you can understand my meaning.

One way could be to use the
FindWindow() function

I haven't tried it myself but if you get success doing the same please intimate me

Have you tried CWnd::GetNextWindow.
MSDN description of function says

"Searches for the next (or previous) window in the window manager’s list. The window manager’s list contains entries for all top-level windows, their associated child windows, and the child windows of any child windows.

If CWnd is a top-level window, the function searches for the next (or previous) top-level window; if CWnd is a child window, the function searches for the next (or previous) child window."

Use this function on main frame window .
In document class you can get main window by using function AfxGetMainWnd
