问题 I am a newcomer to programming. I am writing a dialog based application which has a static control on it. Using Using void CMy1stDlg::OnMouseMove(UINT nFlags, CPoint point) { if (this == GetCapture()) { CClientDC aDC(this); aDC.SetPixel(point, RGB(255,0,0)); } } I can create results like However what I want is that the locus of mouse is only drawn within the static window. I can't find the reference to this in MSDN and I don't know why the following method fails. void CMy1stDlg::OnMouseMove

问题 I have been using gtest as my C++ unit-test framework, and it works great for console applications. Does anybody know if it is possible to use this (or which would be a good alternative) for testing an MFC application? I mean, make an automatic test depending on the events of the GUI (text inside text-boxes, buttons clicks and so). I have seen applications like TestComplete, but I would like to know if gtest offers something similar or if there is a free/opensource alternative to start with.

问题 How to get handles of all the child windows in Mozilla firefox. Spy++ is showing only one class and window caption for all the windows. I tried using GetWindow and FindWindowEx but got nothing. I want to read URL from mozilla firefox. 回答1: Spy++ uses standard Windows API calls to inspect window hierarchies (EnumWindows, EnumChildWindows, etc.). If Spy++ doesn't show any native windows, then there aren't any native windows. Consequently, you cannot find any native windows either. Firefox uses

问题 I am trying to send some simple mouse down/up messages to Windows Calculator using SendMessage. I have been able to press the buttons by sending the messages to the buttons directly. However, I have not been able to successfully send the same messages to the main calculator window handle. Given that hWnd is the window handle to calculator, this is my code. IntPtr fiveKey = FindWindowEx(hWnd, IntPtr.Zero, "Button", "5"); int x = 5; // X coordinate of the click int y = 5; // Y coordinate of the

问题 I need to build a window designed to look exactly like this (it has controls inside the white area, but that's not relevant for now): http://dl.dropbox.com/u/3432167/example.png My problem is defining those two separate "areas" with different backgrounds. The closest I've got to the expected look was representing the white area with an empty ListBox, but the result is not the same (and it is a lousy hack). Any ideas on how achieve this? 回答1: If the dialog does not need to be resizable, the

问题 I have an MFC List Control in Visual Studio 2013 (C++) with a List of items (Report view) LVCOLUMN lvColumn; lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH; lvColumn.fmt = LVCFMT_LEFT; lvColumn.cx = 120; lvColumn.pszText = "Full Name"; ((CListCtrl*)GetDlgItem(IDC_LIST1))->InsertColumn(0, &lvColumn); lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH; lvColumn.fmt = LVCFMT_LEFT; lvColumn.cx = 75; lvColumn.pszText = "Profession"; ((CListCtrl*)GetDlgItem(IDC_LIST1))->InsertColumn(1, &lvColumn)

问题 If I make a new button class inheriting from CButton , specifying the BS_OWNERDRAW style , and overriding the DrawItem method I can control the rendering of the button, like this: void CMyButton::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct) { CDC dc; dc.Attach(lpDrawItemStruct->hDC); RECT rect = lpDrawItemStruct->rcItem; dc.FillSolidRect(&rect, RGB(0, 0xFF, 0)); dc.Detach(); } m_button.Create(L"Foo", WS_CHILD | WS_VISIBLE | BS_OWNERDRAW, CRect(0, 150, 100, 200), this, IDC_FOO); I get the

问题 I have asked two questions earlier about this and for each post there was some solutions i tried them, but the problem still exist. My first question was : why a windowless Activex does not return the Handle. the suggestion was "change the creation setting an make windowless activate off, i have tried it but still m_hWnd property has returned zero as GetSafeHwnd() method has did. the second one was the same question this one focused on COleControl class and it's ancestor CWnd. the solution
