I am doing the following -----------------.h file--------------- struct CNode { long x; _bstr_t b; _bstr_t c; }; class A { ... typedef std::list<cnode*> SEC_MSG_DATA; SEC_MSG_DATA node; ... } -------------------------------------------------- I am trying to acces the member of the structure CNode through the object pointer of class A (pA->node.x) however i am getting the error "is not a member of 'list<struct cnode="" *,class="" std::allocator<struct="" *=""> >'" Can you please help me. Thanks Re: Link List using STL Jeff Thompson28-Oct-05 18:37 Jeff Thompson 28-Oct-05 18:37  Hi, I'm not sure I understood exactly what you're trying to do, but if you're trying to create a linked list of pointers to CNode's, then try this: std::list<CNode*> nodes; Then you can add to the list via pA->nodes.push_back(xxx). To traverse the list, you can something like: std::list<CNode*>::iterator itNode; for( itNode = nodes.begin(); itNode != nodes.end(); itNode++ ) { CNode *pNode = *itNode; // do something with pNode here } Hope that helps, -- jthomps how to implementate a registration script T.J.27-Oct-05 22:49 T.J. 27-Oct-05 22:49  Hello, I dont know, how to implementate a registration script "hInstance needs to be the module / instance handle of the module that contains your server registration script (resource ID 102) .." the server registration script is importand to register my OPC Server. RegisterServer() HRESULT RegisterServer(void) Return Values S_OK upon success, otherwise the result code returned from the ATL registrar component. The success of this operation is dependent on the application including a registry script resource as part of its EXE. The resource ID MUST be 102. An example resource script is shown below: HKCR { NDI.SimulationSvr.1 = s 'NDI Simulation Server' { CLSID = s '{1E52DE00-FA5E-11d2-91C6-F8E932000000}' ... Best regards Thomas ATL COM Program LiYS27-Oct-05 17:06 LiYS 27-Oct-05 17:06  Never used ATL COM, but today I came across a little ATL COM test program, it is created by ATL COM AppWizard, all the settings are by default. a new ATL object was added into the project, and a new property Score with it. STDMETHODIMP CContrl::put_Score(float newVal) { // TODO: Add your implementation code here MessageBox("afsf"); return S_OK; } Then I inserted this ActiveX Contrl into another Dialog base project, and when Score property value was changed, the message box was prompted. But the problem is when I add this contrl to a webpage inside Frontpage and going through the same process, the message box doesn't shows up Re: ATL COM Program User 21559727-Oct-05 20:17 User 215597 27-Oct-05 20:17  For using on WebPage, I think, you will need to do some settings using DCOMCnfg.exe. I am not sure, check out. Have a great day ahead! Regards, Sohail Kadiwala (My Blog - http://blogs.wdevs.com/sohail/[^]) modified 21-Apr-21 21:01pm.

Help: complie error when define struct in atl7.0 dog.in.yellow22-Oct-05 16:34 dog.in.yellow 22-Oct-05 16:34  Hello! I have a problem when define struct in atl 7.0. I develop it in vc.net. That's part of code below: My com component has a face ISimpleFace: //FILE SimpleFace.h //my costum struct struct tPosition { double x; double y; }; // ISimpleFace [ object, uuid("1C499BAD-9BAE-47AF-966F-EB972FA8DF47"), dual, helpstring("ISimpleFace 接口"), pointer_default(unique) ] __interface ISimpleFace : IDispatch { [id(1), helpstring("方法TestStruct")] HRESULT TestStruct([in] struct tPosition pos); }; When I complie it, out some errors: e:\work\mysimpleface3\simpleface.h(23) : error MIDL2011 : unresolved type declaration : tPosition [ Parameter 'pos' of Procedure 'TestStruct' ( Interface 'ISimpleFace' ) ] e:\work\mysimpleface3\simpleface.h(23) : error MIDL2009 : undefined symbol : [ Parameter 'pos' of Procedure 'TestStruct' ( Interface 'ISimpleFace' ) ] What's the problem,how to define a struct in vc.net? Is there somebody can help me? Thanks! Re: Help: complie error when define struct in atl7.0 Igor Vigdorchik23-Oct-05 16:21 Igor Vigdorchik 23-Oct-05 16:21  I believe that you need to define your struct in .idl file. See what MSDN has on this issue. Re: Help: complie error when define struct in atl7.0 dog.in.yellow24-Oct-05 5:20 dog.in.yellow 24-Oct-05 5:20  Thanks for your reply! But I do it with COM Attribute Program. The complier genrates idl file for me automately. How to define a struct in Attribute Program. Re: Help: complie error when define struct in atl7.0 Igor Vigdorchik24-Oct-05 7:14 Igor Vigdorchik 24-Oct-05 7:14  Edit the idl file manually and define your struct there. Check MSDN, it should have a lot of info. Re: Help: complie error when define struct in atl7.0 User 21559727-Oct-05 20:20 User 215597 27-Oct-05 20:20  I haven't used Attributed programming in ATL. Try adding the UUID attribute to your structure - [ uuid("your uuid"), helpstring("custom struct") ] struct tPosition { double x; double y; }; Have a great day ahead!

Re: Help: complie error when define struct in atl7.0 User 21559729-Oct-05 4:08 User 215597 29-Oct-05 4:08  As I mentioned I never worked with Attributed programming.

AddressSpace of Hooked function Abhinav agrawal20-Oct-05 20:01 Abhinav agrawal 20-Oct-05 20:01  Hi All, I have created one system wide hook in one of my dll file say myHook.dll like this: hGetMsgHook = SetWindowsHookEx( WH_GETMESSAGE, GetMsgProc, (HINSTANCE)hmodHook, 0 ); Now the confusion is that, while anyprocess sends any message, This function will be called from within the address space of that process itself or outside that proecess. Which process address space this function will map to? Just like in setWinEventHook API we have one flag for setting this WINEVENT_INCONTEXT or WINEVENT_OUTOFCONTEXT, dont we have anything to control the same for SetEindowsHookEx API? Thanks in advance for all your suggestions...

Which process address space this function will map to? WH_GETMESSAGE can be created as a global or a thread specific hook. If you created it as a global hook it is mapped (AFAIK) to all of the processes in the system (well, the current desktop). Specific calls to your hook come from the address space of the process that called GetMessage or PeekMessage. RemoteLib uses global hook to inject any dll to the target process: -it installs a global hook -it then forces the hook to be balled by sending a message to the target window -when the hook is called, the hook procedure calls LoadLibrary from the target process space and thus loads the dll too the target process space.

Allowed on Property, method, coclass, dispinterface, interface, library. Comments This attribute allows members to be removed from an interface by shielding them from further use, while maintaining compatibility with existing code. When specified for a library, the attribute prevents the entire library from being displayed. It is intended for use by controls. Hosts need to create a new type library that wraps the control with extended properties.

I have a dll that has only one ATL object. Now, I need to add a second one, and I would like to add to the same dll (this way I don't need to register a new dll, just the old one with the new object!). I add it using the VC6 wizard, it compiles ok, but when I try to use it via VB, it gives the error "Can't create activex object!". It's not a problem in the code, since if I put it in a stand alone dll it runs ok. Does any one knows what kind of magic I need to do to make it run? ALMC
