• Myime no Code Snippets in C++?

  Somewhere I read that code snippets are not aplicable in C++ code. Is that true and why I only want to use snippets to insert documentation templates for classes, functions etc. at a first look I do not see any technical reason for not supporting that feature. Thanks for your help, Tobias No Insert Snippet, no Snippets folder in the VC folder and no Snippets editor. Perhaps it has something to do with C++ class declarations and metho ...Show All

• TGrant misuse of strcpy_s in CPUID example

  The file cpuid.c in the CPUID example uses a lot of strcpy_s calls in the map_mname function. These calls are malformed however... The length of the destination string (m_name) is unknown so the length of the source string is used (erroneously) instead. I have replaced the void function, map_mname, with a function that returns (const char *) and it returns the string litteral. I replaced each pair of strcpy_s(); break; statements with a retur ...Show All

• Jaapjan Tinbergen How can I test if a gcroot<String^> has a String assigned to?

  There must be a way to test if my "gcroot<String^> m_aString" has been a real String assigned to (by executing "m_aString = gcnew String(L"")"), but I cannot find it. The compiler accepts my setting the variable to nilptr (m_aString=nilptr) but wouldn't allow asking "m_aString == nilptr". I tried countless other ways, but to no avail. Can anybody tell me how to do it -- Manfred Thanks, this works fi ...Show All

• SGrieco ODS_SELECTED for MFC CMenu::DrawItem no longer works?

  Hi all, I write an application with MFC owner-draw menu. Under windows XP it works fine, but under windows Vista Beta2 5320, my DrawItem() no longer receives the selection status of the menu item. The code looks like this: ...(omitted) if (lpDrawItemStruct->itemState & ODS_SELECTED) { (draw selection rectangle) } After tracing, I found that itemState will never have ODS_SELECTED turned on.
