David,
Thank for replying. Let me share some details...
i have created the listview control. I tried to create the listview in the function OnInitialUpdate and it worked successfully.
My need is to keep both windows open like receiver and sender mechanism i.e. Data is passed from one form having edit control and after sending data, display them in listview in separate form. But when i tried to do the same in my defined function (in addition to OnInitialUpdate) i.e. AddData(), I face this problem.
The sequence of code follows. Both Functions exist in the same cpp file.
void CTestView::OnInitialUpdate()
{
CFormView::OnInitialUpdate();
ResizeParentToFit();
m_pSelection = NULL; // initialize selection
CListCtrl* pList = (CListCtrl*) GetDlgItem(IDC_LIST1); // THIS ONE WORKS
pList->InsertColumn(0,"ym",LVCFMT_CENTER,140);
pList->InsertColumn(1,"Ws",LVCFMT_CENTER,70);
pList->InsertColumn(2,"State",LVCFMT_CENTER,50);
}
void CTestView::AddData(LPCTSTR tn,LPCTSTR cn,LPCTSTR ts,LPCTSTR cv)
{
int i=0,j=0;
int flag = 0;
j=rowcount-1;
//pointer to the listview control
CListCtrl* pList = (CListCtrl*) GetDlgItem(IDC_LIST1); // THIS ONE DOES NOT WORK
pList->InsertItem(0,ts);
}

Why are you creating a list view at runtime rather than deriving the view from CListView? This would allow you access to the underlying list control using GetListCtrl().
If, however, you are using a CFormView with a list control instead, create a CListCtrl member variable instead of using GetDlgItem().
When does AddData() get called?

I am using a CProgressCtrl m_PPROG in my main dialog class;
how can i call m_PPROG.SetPos(value) from another function in another class without creating another object of the main class?

Since the progress control is owned by your "main dialog class," good design dictates that only that dialog should interact with the progress control. If some other class needs to interact with the control, it should send/post a message to the owning dialog class, or the owning dialog class should have a public method, that others can call, for setting the control's position.

I am trying to figure out if the current desktop is the desktop that my interactive service is running on, and I came across the GetInputDesktop function exported by user32.dll. It appears to always return 0 if either the login screen or screen saver or a fast user switching terminal services desktop is active. So, I simply compare the returned HDESK value of that to the value returned by GetThreadDesktop and I have my answer. But since GetInputDesktop is undocumented, I'm wondering if there is another way to get at this information, or if anyone knows anything more specific about the GetInputDesktop function.
Thanks much.

Yes, GetThreadDesktop is documented. However, GetInputDesktop is not. That is the function I'm curious about.

My bad.  Thread and Input just look so much alike!

Never worked with this, but there's a documented OpenInputDesktop(), which (quote) "retrieves a handle to the desktop that receives user input. The input desktop is a desktop on the window station associated with the logged-on user."
Would that be of help?

Wat function do i call to get a bool parameter indicating that my window has the focus or not?

Use GetFocus() for this.

GetFocus returns a handle of the window but how can i know that this is the window i want or not?

if (GetFocus() == GetDlgItem(IDC_MY_WINDOW)) {
}

because you don't use it properly...
post your code

|
|

if (Lp.checkcon2() && (GetFocus() == GetDlgItem(IDD_AUTOMATIC)))
forget about Lp.checkcon2() it is always true
/\|-||\/|/\|)

hum, what about GetFocus() == m_hWnd ??
moreover, are you sure that GetDlgItem() doesn't return NULL ?!

i received this error message
error C2446: '==' : no conversion from 'struct HWND__ *' to 'class CWnd *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
error C2230: '==' : indirection to different types
Error executing cl.exe.
maybe it doesnt work when this is not the main dialog?

GetDlgItem() is returning NULL
WHY?

Because no such control having an id IDD_AUTOMATIC exists at the point in which GetDlgItem() is being called.

Why would that surprise you?

I've yet to figure out why people do this and then complain that it does not work.
To figure out exactly which part of the above statement is not working, break it up into manageable pieces, like:
CWnd *pWnd1 = GetFocus();
if (pWnd1 != NULL)
{
CWnd *pWnd2 = GetDlgItem(IDD_AUTOMATIC);
if (pWnd2 != NULL)
{
if (pWnd1 == pWnd2)
...
}
}At this point, you should know the return value of GetFocus() and GetDlgItem() and whether they are equal or not.
