This is the code that i have used for checking.. This code works correctly..it changes the cursor to IDC_HAND when the mouse is over the subitem number 1.

void MyList::OnMouseMove(UINT nFlags, CPoint point)
{

static HCURSOR hCursor = LoadCursor( 0, IDC_HAND );
LVHITTESTINFO lvhitTestInfo;
lvhitTestInfo.pt = point;
int nItem = SubItemHitTest(&lvhitTestInfo);
int nSubItem = lvhitTestInfo.iSubItem;
if (nItem >= 0 && lvhitTestInfo.iSubItem > 0)
{
int m_nSubItemHit = lvhitTestInfo.iSubItem;
if ( lvhitTestInfo.iSubItem == 1)
{
SetCursor(hCursor);
}
}

CListCtrl::OnMouseMove(nFlags, point);
}

I think better is to handle the cursor in OnSetCursor... What do you think?

Consider a solution in which you handle the WM_SETCURSOR notification. Within the OnSetCursor handler, obtain the mouse coordinates with GetCursorPos, make a test and call SetCursor to set your cursor, then return TRUE. Otherwise, call the parent OnSetCursor handler and return its value.

Hope it will work.

Can window be create in a window service?

You forgot to convert the points (pMessage->pt) to client coordinates, because they are in screen coordinates. Smile | :)

On Win 2K or later, you can register COM servers on a per-user basis under HKCU\software\classes

Capture it in your CFormView's WM_KEYDOWN and WM_KEYUP.

Derive a class from CEdit and make the object of this class as member variable of the edit control.

Overide the WM_KEYDOWN message in the new class and then u can trap the enter key fro that funtion...

here i have derived a class from the CEdit say EditCtrlEx . Then using the class wizard i mapped the WM_KEYDOWN message( this will create a stub function with name void EditCtrlEx::OnKeyDown( UINT uChar_i, UINT uRepCnt_i, UINT uFlags_i )

inside this write

void EditCtrlEx::OnKeyDown( UINT uChar_i, UINT uRepCnt_i, UINT uFlags_i )
{
CEdit::OnKeyDown( uChar_i, uRepCnt_i, uFlags_i );
if( VK_RETURN == uChar_i )
{
AfxMessageBox( _T("Enter clicked ));
}
}

Remeber to give the Want-Return style to the edit ctrl

Hi ,
Add the ON_WM_GETDLGCODE() along with the above code

UINT Cmyedit::OnGetDlgCode()
{
return CEdit::OnGetDlgCode()|DLGC_DEFPUSHBUTTON|DLGC_WANTALLKEYS;
}
