# include <comdef.h>
CComPtr<ADOConnection> p_Con;
CComPtr<ADORecordset> p_Rst;
CoCreateInstance (CLSID_CADOConnection, NULL,
CLSCTX_INPROC_SERVER,IID_IADOConnection,
(LPVOID *) &p_Con);

Hi Friend,
I want to create a link list using STL. 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

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,

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

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)
{
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

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!

AX controls have to be marked "safe" before you can use them in IE. Look up IObjectSafetyImpl in MSDN.

Hi Friends,
I am store some data into vector and mapping it long key for searching (1::1 mapping).Below code
---------------------.h file------------------------
typedef std::vector<item *=""> m_cache;
typedef std::map<long, item="" *=""> m_index;
typedef std::pair<long, item*=""> INDEX_ENTRY;
INDEX_ENTRY IndexEntry(Item * plu);
--------------------.cpp-------------------------
m_cache.push_back(item);
m_index.insert(IndexEntry(item));
-------------------------------------------------
Now the requirment is to retrive the same data with any of 2 different key long1 and long2 from the same vector(1::2 mapping). Can you please help me how to do this?
Thanks

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!

I believe that you need to define your struct in .idl file. See what MSDN has on this issue.
|
|
|
|
|
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.
|
|
|
|
|
Edit the idl file manually and define your struct there. Check MSDN, it should have a lot of info.
|
|
|
|

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!

Thanks for your reply!
But add a UUID attribute is not help.

As I mentioned I never worked with Attributed programming. I'll watch this question for appropriate answer. Incase you find answer to your problem, please share here. Thanks.
Have a great day ahead!

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...

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.
