问题 I have 2 dialog and I´m trying to embedded one to another. It is accomplished by setting style of embedded dialog to WS_CHILD. It works correctly, but embedded dialog has wrong (default windows) style. Is it windows thing, that cannot be changed, or is there any way to fix it? I tried to changed all options for both dialogs in resource editor, but none seems to work. Main dialog is normal modal dialog. Embedded dialog is created in OnInitDialog() of main dialog like CDialog m_dlg1; m_dlg1

问题 I'm attempting to write a simple MFC app that draws in a scrollable window, using code based on CFrameWnd. The code below is adapted from Prosise "Programming Windows with MFC", 2nd ed, pp 89ff. When I run this in the debugger, I get two first-chance exceptions. If I ignore these, the window appears as expected, and I can draw in it. If I enable break on "C++ exceptions", I get a stack which is only "internal" code, for which I do not have the source. By stepping through the code, I find that

问题 For example, COMDLG32.DLL implicitly links against the following system DLLs (among others): xmllite.dll msftedit.dll srvcli.dll wkscli.dll linkinfo.dll netutils.dll msi.dll Since these are implicitly loaded by the operating system, not explicitly loaded using LoadLibrary call, the hijack vulnerability workaround using SetDllDirectory does not affect these loads being done when COMDLG32.DLL is loaded. Hence, after my application is loaded, and I hit Ctrl+O to use the File Open dialog, these

I absolutely need to perform some manipulations on items dynamically added to my CListCtrl. Ultra-Basically, I need to: Detect adding of single elements; Retrieve _single items_ IMMEDIATELY AFTER(ideally, shortly after InsertItem() invocation); Store values of single items in a map, which I will use to perform other manipulations. I thought about doing this

问题 Is MFC is based on any design pattern,if so which design pattern?? 回答1: MFC and Design Patterns As we all know, MFC is one of the popular class libraries used by C++ programmers. The success story behind MFC is its class architecture and design principles adopted by the developers of MFC, which makes it one of the popularly reused library. The main focus is to show how patterns are used in MFC. We will be seeing the usage of three patterns in MFC library. Creational : Singleton Pattern First

问题 Lets say I have an MFC Dialog with several buttons on it. (E.g. "Red", "Blue", "Green", and "Yellow" buttons) These buttons all have IDs such as ("IDC_BUTT_RED","IDC_BUTT_BLUE","IDC_BUTT_GREEN","IDC_BUTT_YELLOW") Given that I have a CWnd object that references the dialog window that these buttons are placed on. Is there a way to get a list of these IDs? I know there is a CWnd::GetNextDlgGroupItem method, that based on the description should iterate through a group of controls. I tried using

问题 I am using this code: m_bmpSwap.LoadBitmap(IDB_BITMAP2); pMnuPopup->SetMenuItemBitmaps(0, MF_BYPOSITION, &m_bmpSwap, &m_bmpSwap); It looks like: It was only a test image: How exactly do I get my image to look as if it has a transparent background? It is 24 bit image. I have seen this but I can't work it out. I adjusted to a 8 bit image with 192/192/192 as the background and loaded like this: HBITMAP hBmp; hBmp = (HBITMAP)::LoadImage(AfxGetResourceHandle(), MAKEINTRESOURCE(IDB_BITMAP2), IMAGE
