i got some more errors..that everything i fixed...exept one..that is
Error 1 error LNK2001: unresolved external symbol _CLSID_ABC ABC.obj AppFast
Error 2 fatal error LNK1120: 1 unresolved externals .........ABC.dll 1 ABC
the code is like this..in my header file
EXTERN_C const CLSID CLSID_ABC;
#ifdef __cplusplus
class DECLSPEC_UUID("97676011-B0FA-40cf-AECC-7BD3FF54BE4E")
ABC;
#endif
what is wrong...i dont know much about c++

You probably should just have opened the VC6 project in VS2008 - it would have converted it to the right format just fine.

I suspect that DECLSPEC_UUID doesn't mean quite the same as it used to or something. You need to add a definition of CLSID_ABC to a .cpp file somewhere.

Dear Stuart
Uuid is same only..
i have a doubt
#ifndef __AppFastLib_LIBRARY_DEFINED__
#define __AppFastLib_LIBRARY_DEFINED__
/* library AppFastLib */
/* [helpstring][version][uuid] */
EXTERN_C const IID LIBID_AppFastLib;
#endif /* __AppFastLib_LIBRARY_DEFINED__ */
/* Additional Prototypes for ALL interfaces */
this is generating at compiling time in ABC_i.h
if i m manualy trying to add my code. That would be deleted...
EXTERN_C const CLSID CLSID_ABC;
#ifdef __cplusplus
class DECLSPEC_UUID("97676011-B0FA-40cf-AECC-7BD3FF54BE4E")
ABC;
#endif
how do i add this class instant in ABC_i.h
Regards
Rajeesh

I've just had a look at an ATL project I've got. The CLSID for my class is defined in my equivalent of ABC_i.c - is that file (ABC_i.c) being compiled and linked in your project?

i dont know much more abt this vc++..
how do i link my class to this ABC_i.c
i need to give any reference or any alternate methord..??
After compiling...ABC_i.c is generating...with out my CLSID of my class
|

Right-click on ABC_i.c in Solution Explorer and select Properties. Under Configuration Properties->General, the 'Excluded from Build' property should be set to 'No'.
Now rebuild the project. At some point, in the output window, you should see mention of ABC_i.c - that means it is being compiled. Hopefully the project will automatically link with ABC_i.c - if it doesn't, I'm not sure why....

| Debuge the COM(ATL) [modified] | | anzhiyue | 16:00 16 Apr '09 |

I create a COM using the ATL in VS2005,it only include one interface,which contains one property(get/put).in order to debug the COM,I create a C# programe and set a breakpoint in the COM,"The breakpoint will not currently be hit. No symbols have been loaded for this document",why??? thanks!

That's because the C# program doesn't know that it'll be loading your COM DLL - it only loads the DLL at run-time. To debug a COM DLL, I would set the DLL project as your startup project and tell it which executable (i.e. your C# executable) to use in the 'Command' property of the project's 'Debugging' property page.

Hi,
I have a link my html page and onclick of that i need to download
and run the msi(ie i need to run a command in client like "msiexec /i http://(servername)/(virtual directory name)/test.msi ALLUSERS=1 /PASSIVE" )
which is present in the webserver(IIS 5 or IIS 6)...(it"s an intranet application)
as of now im using Wshell.Run(vb script) to run msi ...but it works fine only when the option "Initialize and script ActiveX
controls not marked as safe" under Tools\internet
options/Security/Customlevel/ActiveX controls and plugIns ,is set to prompt or enable .....
So i thought of creating my own ActiveX control (signed) with certificate...instead of using Wshell...but im not sure whether
i can achieve this...please help me regarding the same....and correct me if im wrong

| STL vector, search for a sequence | | kaminem | 23:16 13 Apr '09 |
|

Hi guys,
I have two vectors of string
and I'm looking for an easy way to find the first vector sequence or sub-sequence into the first one
for example:
Vect_1 < "JAVA", "ADA", "C", "C++", "C#">
Vect_2 < "C++", "C#">
search vect_2 sequence in vect_1 will return vect_1 position 3 and match length 2
Vect_1 < "JAVA", "ADA", "C", "C++", "C#">
Vect_2 < "JAVA", "C#">
search vect_2 sequence in vect_1 will return vect_1 position 0 and match length 1
thanks for any idea, suggestion

The simplest algorithm is probably this:
std::pair<size_t, size_t> find_first_subsequence(std::vector<std::string> const& v1,
std::vector<std::string> const& v2)
{
std::vector<std::string>::const_iterator pos = std::find(v1.begin(), v1.end(), v2[0]);
const size_t firstPos = pos-v1.begin();
if (pos == v1.end()) return std::make_pair(-1, -1);
size_t numEqual = 0;
while(numEqual < v2.size() && pos != v1.end() && *pos == v2[numEqual])
{
++numEqual;
++pos;
}
return std::make_pair(firstPos, numEqual);
}

Because std::search only returns a match if it finds the whole of a sequence you're looking for, not a partial match, which is what the OP was looking for.

| AtlAxAttachControl - An outgoing call cannot be made since the application is dispatching an input-synchronous call. | | bfoo75 | 14:19 9 Apr '09 |
|

I'm at the end of my rope here... I've been bashing my head on my keyboard for the last week trying to figure out this issue.
I'm trying to display a flash control on a DirectDraw surface and my call to AtlAxAttachControl fails - preventing the flash player from appearing within the control.
Here's a stripped down version of my code:
#pragma once
#include <string>
#include <windows.h>
#include <exdisp.h>
#include <mshtmlc.h>
#include <atlbase.h>
#include <atlcom.h>
#include <atlwin.h>
using std::string;
#import "PROGID:ShockwaveFlash.ShockwaveFlash" no_namespace raw_interfaces_only
typedef HRESULT (WINAPI *LPAtlAxWinInit) ();
typedef HRESULT (WINAPI *LPAtlAxGetControl)(HWND hwnd, IUnknown** unk);
class FlashViewer
{
public:
FlashViewer();
~FlashViewer();
bool Init(int Width, int Height);
void OpenFlash(const char* filename);
void DrawToSurface(LPDIRECTDRAWSURFACE7 lpdds);
private:
int mViewerWidth;
int mViewerHeight;
HWND mViewerWnd;
IShockwaveFlash* mFlashCtrl;
};
FlashViewer::FlashViewer()
{
mViewerWidth = 0;
mViewerHeight = 0;
mViewerWnd = 0;
mFlashCtrl = NULL;
}
FlashViewer::~FlashViewer()
{
DestroyWindow(this->mViewerWnd);
if (this->mFlashCtrl != NULL)
{
this->mFlashCtrl->Release();
this->mFlashCtrl = NULL;
}
}
bool FlashViewer::Init(int width, int height)
{
LPAtlAxWinInit AtlAxWinInit3 = (LPAtlAxWinInit)GetProcAddress(LoadLibrary("atl"), "AtlAxWinInit");
LPAtlAxGetControl AtlAxGetControl3 = (LPAtlAxGetControl)GetProcAddress(LoadLibrary("atl"), "AtlAxGetControl");
MSG msg;
HRESULT hr = AtlAxWinInit3();
HWND hwnd = CreateWindow("AtlAxWin", "", WS_VISIBLE|WS_POPUP, 0, 0, 1024, 768, 0, 0, 0, 0);
IShockwaveFlash* flash = 0;
hr = CoCreateInstance(__uuidof(ShockwaveFlash), 0, CLSCTX_ALL, __uuidof(IShockwaveFlash), (void **)&flash);
hr = flash->put_WMode(L"transparent");
hr = flash->put_Loop(true);
hr = AtlAxAttachControl(flash, hwnd, NULL);
hr = flash->put_Movie(L"c:\\FrontEnd.swf");
long pVal = -1;
flash->get_ReadyState(&pVal);
return true;
}
void FlashViewer::OpenFlash(const char *filename)
{
this->mFlashCtrl->LoadMovie(0, _bstr_t(filename));
}
void FlashViewer::DrawToSurface(LPDIRECTDRAWSURFACE7 lpdds)
{
if (this->mViewerWnd == NULL)
return;
RECT rect = {0, 0, this->mViewerWidth, this->mViewerHeight};
HDC hdcSurface;
HRESULT hr = lpdds->GetDC(&hdcSurface);
if (FAILED(hr))
return;
SetMapMode(hdcSurface, MM_TEXT);
OleDraw(this->mFlashCtrl, DVASPECT_CONTENT, hdcSurface, &rect);
lpdds->ReleaseDC(hdcSurface);
}
When debugging - the console displays two First-chance exceptions as soon as AtlAxAttachControl() is called... Both are 0x8001010D: An outgiong call cannot be made since the application is dispatching an input-syncronous call.
This problem is totally driving me crazy... PLEASE SOMEONE HELP.

I suspect that it's a COM threading issue. Do you have a single threaded app or maybe a single-threaded apartment model app? Is FlashViewer::Init called from within a COM method?

Hi everyone:
Just like the subject, thanks.

If it's a non-template class and you export it from the DLL[^], sure, why not?

OK, thanks for your reply, I have fixed the problem, the exe need to choose link to ATL.

| Is there anyway to authenticate the COM client? | | lucyh3h | 7:05 30 Mar '09 |
|
|
Hi,
I have a COM server (not DCOM) and would like to only accept calls from one known client. Is there anyway that the COM server can find out the caller's information and determine if the client is trusted?
I've seen the documents about the security features, mostly for DCOM, that usually involve user authentication. But in my case, both client and server runs on the local machine.
Thanks,
|

hmm, that is not exactly what I need. I looks like I can find out the user information, who runs the client. But not the client process itself.
Is there anyway I can find out more client information, for example, the client process id.

You could get the client to tell you its process id?

No, I am trying to authenticate the client, so I don't trust whatever it tells me.
I guess this is an issue common to all Local RPC. Does the server always trust the client running on the same machine?
|
|
|
|
|
|

I suspect the standard COM security API[^]s are the only real way to authenticate the client.

| Is forward declaration of ATL autogenerated _com_ptr_t possible? | | Stone Free | 5:17 26 Mar '09 |
|
|
In normal C++ when a class header only contains a reference or a pointer to a class it is better to not #include the definition but wait until the .cpp file to avoid coupling/avoid recompilation.
In our of our class headers the reference concerned is to a smart pointer generated from a #import, in other words a smart pointer of the form _COM_SMARTPTR_TYPEDEF(IComInterface, &__uuidof(IComInterface))
Which expands to typedef _com_ptr_t<_com_IIID<icominterface,> > IComInterface;
I think the problem is that the __declspec(uuid("GUID VALUE")) which is attached to the forward declaration of the IComInterface struct like __stdcall and __fastcall is part of the declaration and so will produce different types depending on the contents of uuid. The problem however is that the uuid contents will be autogenerated by the #import line, and so it won't be possible know ahead of time to know what to put in the typedef.
I also think that the $(InputName)_i.c file generated when building the COM component won't help because although it contains the correct GUID it won't be in the correct form for __uuidof
