I am working with an old ATL/COM project in Visual Studio 2017. In previous versions of Visual Studio you could select "Add Class" and then select the option "Add simple ATL object" to add a COM class to the project. This option appears to be completely missing in Visual Studio 2017. Has the option been moved? Have I missed an installation option? Does Visual Studio fail to recognize my project as an ATL project? (It was created with a much older version.) Or is this the end of the road for ATL? I'm not sure whether this an answer, but it is too much for a comment and more than just an edit to

Resource scripts loaded from .rgs files are used with ATL CComModule::UpdateRegistryFromResource() . It's quite common to see samples of such files on the net but I've never seen a complete description on what constructs are allowed in .rgs files. Is there such a document? There's some MSDN documentation , but it appears to be pretty unfocused. The book ATL Internals talks at some length about custom replacements. Other than that, I haven't seen much... 来源： https://stackoverflow.com/questions/1594283/is-there-a-document-on-rgs-files-syntax

In the .rgs file, there are some registry info, and I want to know how does the info in .rgs file added into regetry? I have a project AAA and it will generate the file AAA.DLL , and there is a file xxx.rgs which contains the registry info, and the AAA.DLL is built, then it will be deployed to another machine B, so I don't know how the registy info can be added on machine B, do I need register AAA.dll using regsvr32 command? Usually your code calls CComModule::UpdateRegistryFromResource() which in turn passes control to a special mechanism implemented in ATL which does the job - parses the

I have a COM function that should return a SafeArray via a LPSAFEARRAY* out parameter. The function creates the SafeArray using ATL's CComSafeArray template class. My naive implementation uses CComSafeArray<T>::Detach() in order to move ownership from the local variable to the output parameter: void foo(LPSAFEARRAY* psa) { CComSafeArray<VARIANT> ret; ret.Add(CComVariant(42)); *psa = ret.Detach(); } int main() { CComSafeArray<VARIANT> sa; foo(sa.GetSafeArrayPtr()); std::cout << sa[0].lVal << std::endl; } The problem is that CComSafeArray::Detach() performs an Unlock operation so that when the

I have an ATL ActiveX control that raises three events (Connected, Authenticated, Disconnected) which need to be handled in IE/JavaScript. So far as I can tell, I'm doing everything right, specifically: (1) I've told ATL to implement the IProviderClassInfo2 interface, as described here . (2) I've implemented connection points within my ATL project by following the directions here . I now have a CProxy_IMyControlEvents class, with the appropriate Fire_Authenticated(), Fire_Connected() and Fire_Disconnected() implementations. They look more-or-less like this: template<class T> class CProxy

I have created an in-process COM object (DLL) using ATL. Note that this is an object and not a control (so has no window or user-interface.) My problem is that I am trying to fire an event from a second thread and I am getting a 'Catastrophic failure' (0x8000FFFF). If I fire the event from my main thread, then I don't get the error. The second thread is calling CoInitializeEx but this makes no difference. I am using the Apartment threading model but switching to Free Threaded doesn't help. The fact I am trying to do this from a second thread is obviously crucial. Is there an easy way to do

I've written a DLL that creates an ATL CString object. I compile it with Visual Studio 2015 using the "Visual Studio 2015 - Windows XP (v140_xp)" platform toolset. The DLL is loaded using LoadLibrary/GetProcAddress. It crashes under Windows XP in CAtlStringMrg::GetInstance when allocating the string object. The same application works well on Windows Vista and later. Here is the disassembly: static IAtlStringMgr* GetInstance() { #pragma warning(push) #pragma warning(disable: 4640) static CWin32Heap strHeap( ::GetProcessHeap() ); 1003B100 mov eax,dword ptr fs:[0000002Ch] 1003B106 mov ecx,dword
