问题 I have an MFC application that uses an ancient (circa 1999) third-party ActiveX control. Since upgrading the project from VS2008 to VS2010, I'm having problems... In the OnSize handler of the parent dialog IsWindow always returns false for the handle returned by control.GetSafeHwnd(), even when GetSafeHwnd() returns a non-NULL value. The rest of the control's parent dialog is displayed fine, but it doesn't seem to respond to any input. I've seen this article, but GetSafeHwnd() isn't returning

问题 I created class CSurfaceWnd from CWnd by Class Wizard. I tried to create window but getting error. That's my code of creating: if(!m_pSurfaceWnd) { CString m_NameClass = AfxRegisterWndClass( CS_VREDRAW | CS_HREDRAW, ::LoadCursor(NULL, IDC_ARROW), (HBRUSH) ::GetStockObject(WHITE_BRUSH), ::LoadIcon(NULL, IDI_APPLICATION)); m_pSurfaceWnd = new CSurfaceWnd; CRect rcTemp; GetWindowRect(rcTemp); VERIFY(m_pSurfaceWnd->CreateEx(WS_EX_CLIENTEDGE, m_NameClass, NULL, WS_POPUP | WS_VISIBLE, rcTemp, mpWnd

问题 I am checking whether a CString variable contains only] Chinese characters. The Unicode range for Chinese characters is 4E00 - 9FFF. I am doing as follows: CString str; char ch; GetDlgItemText( IDC_EDIT1, str ); for(int i=0;i<str.GetLength();i++) { ch=str[i]; if(ch>='\u4E00'&&ch<='\u9FFF') { //even if input chinese character here 'if' evaluates to false SetDlgItemText( IDC_RICHEDIT21, str ); SendDlgItemMessage( IDC_RICHEDIT21, EM_REPLACESEL, TRUE, (LPARAM)(LPCTSTR)str); } else break; But if I

问题 So I created the following test project: [DllImportAttribute("TestMFCDLL.dll", CallingConvention = CallingConvention.Cdecl)] internal static extern int test(int number); private void button1_Click(object sender, EventArgs e) { int x = test(5); } Which works fine for my MFC dll that has the function test defined, however what I actually have is many MFC dlls that all share a common entry function and run differently based on my inputs. So basically I have tons of dlls that I cannot know at

问题 I was trying to derive a custom class from CMFCVisualManagerOffice2007. Can you suggest me steps to be followed in order to derive a CCustomMFCVisualManagerOffice2007?

问题 Yeah, I know that I should make an iterator, but I need this done fast and writing a proper iterator for anything related to VC++ is beyond frustrating. (This also goes for many other standard things and is buggering up my work load. :( ) So I wrote a for_each() algorithm to deal with the nastiness: template <typename K, typename AK, typename V, typename AV> void for_each(CMap<K, AK, V, AV>& container, std::function<void(AK, AV)> body) { POSITION pos = container.GetStartPosition(); while (pos

问题 Normally when you hover over a sub-menu (with the little arrow) on a CMenu menu item it delays briefly then shows the sub-menu items. Also, if you click the item before the delay timeout, it shows the sub menu items. I want the delay behavior, but I want a different behavior for the click. That is, I want the sub-menu itself (the one with the arrow) to be a clickable entity too, i.e. it has an ID and results in a WM_COMMAND and menu dismissal. The idea is, the main sub-menu menu item is a

问题 How can I print a document using MFC Dialog Based Application? I have made a print button. After clicking on this button, I want print of some document or some text. 回答1: You can create an invisble CHtmlEditCtrl control and load your text to it with SetDocumentHTML(LPCTSTR) method and then call PrintDocument() method. void WaitForComplete(IHTMLDocument2* document) { BSTR ready; document->get_readyState(&ready); while(wcscmp(ready, L"complete")) { AfxPumpMessage(); document->get_readyState(
