I am trying to create an activex object using VBScript and I want to release the object after usage. I used the following to do it:

//create
Set obj = CreateObject(SomeProgId)

//code
....
....
//release
Set obj = Nothing

The last part "Set obj = Nothing" which is supposed to release the object from the IE memory does not seem to work. Can some one help me in this regard because this looks like a generic problem that someone would have faced earlier.

First get the string from edit control, you can use GetWindowText(..) or GetDlgItemText(..)

then check for the string in CListCtrl using CListCtrl::GetItem(..) or CListCtrl::GetItemText(..)

then if the string matches do your logic to get the information and display it in second edit box SetWindowText(..) or SetDlgItemText(..)

Hope this'll help

CListCtrl::FindItem() will be more appropriate.

In CWnd sub-class, ScrollBars have been successfully displayed by function SetScrollInfo(...).

but, in both message handles:
OnVScroll(UINT nSBCode,UINT nPos,CScrollBar*pBar)
and
OnHScroll(UINT nSBCode,UINT nPos,CScrollBar*pBar)

the value of pBar is NULL.

GetScrollBarCtrl(...) also returns NULL.

scroll bars are visible and info (nPage ...) is correct, but why pointers to bars can not be obtained.

Do you have idea to get scroll bars of CWnd?

this is because in the CWnd sub-class, the scroll is not a window. Its just a painting. If there is no scroll bar then how can GetScrollBarCtrl() return a winow handle?

I think the pointer is non-null only when the message came from a separately scroll bar control. If the message came from a window having WS_HSCROLL or WS_VSCROLL style, then there is no scroll bar controls (since window uses built-in scroll bars), and the pointer is NULL.

In this case you have to manipulate the scroll bar using CWnd’s members like SetScrollInfo.

do u use MFC?

u only need to read text of edit by function GetWindowText() then check if it is inside of list-box by FindStringExact() (MFC function) - if u use Win32, try to do a little research by read docs/help-files about list-box.

return FALSE;
}
else
{
AfxMessageBox("Inint");
}

_Application app; // app is the Excel _Application object

if(!app.CreateDispatch("Word.Application"))
{
AfxMessageBox("Couldn't start Excel.");
}
else
{
//Make Excel Visible and display a message
app.SetVisible(TRUE);
AfxMessageBox ("Word is Running!");
}

//COleVariant covTrue(true),covFalse(false),covOptional(NULL);

COleVariant
covTrue((short)TRUE), covFalse((short)FALSE), covOptional((long)DISP_E_PARAMNOTFOUND, VT_ERROR), covFormat( short(7));

Documents docs;
_Document oDoc;

oDoc.AttachDispatch( // opening file

Maybe you should try this:

Documents docs = app.GetDocuments();
_Document doc = docs.Open(....);
doc.SaveAs(....);

I hope this works.

Anybody could please provide some useful link to know more about C++ VTABLE.

How the compiler constructs vtable? is it per object basis or per class?

I'd like to know more about some internal stuffs regarding vtable.

WH_MSGFILTER or WH_GETMESSAGE hook will be good. Inside this u can monitor the WM_HSROLL and WM_VSCROLL message...
