Good link...What I am trying to do is slightly different though. In the post, the event sink is the .NET application it self. In my case, the event sink is another COM object and this sink COM object is instantiated from .NET application.
|
|
|
|
|
The only other thing that comes to mind is the Dispatch pointer you're getting ..
I notice you're using dispatch based callbacks into the sink?
Perhaps (and i'm stabbing in the dark here  .Net creates your object as an aggregate object and the IDispatch you get when you query your sink, is not your's it's .NET's ?
|
|
|
|
|
if you import you dll in .net application,you can assign the sink method to your interface directly

hello all .
Actually i want to catch a Wrong Password Attempt to logon a system. Is there any API that can lead me to that event. If there is no then how would i be able to catch that event.
|
|
|
|
|
There is no specific event for that since Windows is not logged on so no applications are running at that time, beyond a few system services. You can learn more about the logon process here[^].

Roughly, it should be possible to:
1. Enable Logon auditing in group policy.
2. Subscribe to that particular event using Event Log API's EvtSubscribe[^]
Your program would need to run as a service, because it's possible that noone is logged in at the very moment. I have to little detailed understandiong of the matter toto provide better help, btu that might get you started.

So here is my problem, I have a c library that I am compiling under CygWin.
I am using Swig to generate a c# wrapper class to it. So I follow the steps to do this. And everything compiles, etc... however..
the defined export names of the functions and constants etc have entry points named in the following fashion:
"swe_sol_eclipse_when_glob"
when I do a 'dumpbin -exports' on the dll the entry points are being named in the fashion of:
"swe_sol_eclipse_when_glob@28"
Is there a way to get rid of the '@xxx' from the names during compilation ?
The makefile is like this:
CFLAGS = -fpic -D MAKE_DLL -g -O9 -Wall # for Linux and other gcc systems<br />
OP=$(CFLAGS) <br />
CC=cc #for Linux<br />
<br />
# compilation rule for general cases<br />
.o :<br />
$(CC) $(OP) -o $@ $? -lm<br />
.c.o:<br />
$(CC) -c $(OP) $< <br />
<br />
SWEOBJ = swedate.o swehouse.o swejpl.o swemmoon.o swemplan.o swepcalc.o sweph.o\<br />
swepdate.o swephlib.o swecl.o swehel.o Sweph_wrap.o<br />
<br />
swetest: swetest.o libswe.a<br />
$(CC) $(OP) -o swetest swetest.o -L. -lswe -lm<br />
<br />
swemini: swemini.o libswe.a<br />
$(CC) $(OP) -o swemini swemini.o -L. -lswe -lm<br />
<br />
# create an archive and a dynamic link libary fro SwissEph<br />
# a user of this library will inlcude swephexp.h and link with -lswe<br />
<br />
libswe.a: $(SWEOBJ)<br />
ar r libswe.a $(SWEOBJ)<br />
<br />
libswe.so: $(SWEOBJ)<br />
$(CC) -shared -o libswe.so $(SWEOBJ)<br />
<br />
clean-swig:<br />
rm -f ../../testsweph
An example of an export is this:
#define EXP32 __declspec( dllexport )
.
.
ext_def(int32) swe_heliacal_ut(double tjdstart_ut, double *geopos, double *datm, double *dobs, char *ObjectName, int32 TypeEvent, int32 iflag, double *dret, char *serr);
An example of the generated c# wrapper:
<pre lang="cs">[DllImport("libswe.dll", EntryPoint="CSharp_swe_heliacal_ut")]
public static extern IntPtr swe_heliacal_ut(double jarg1, HandleRef jarg2, HandleRef jarg3, HandleRef jarg4, string jarg5, HandleRef jarg6, HandleRef jarg7, HandleRef jarg8, string jarg9);
Swig Generated C Wrapper compiled in...
<pre>SWIGEXPORT void * SWIGSTDCALL CSharp_swe_heliacal_ut(double jarg1, void * jarg2, void * jarg3, void * jarg4, char * jarg5, void * jarg6, void * jarg7, void * jarg8, char * jarg9) {
void * jresult ;
double arg1 ;
double *arg2 = (double *) 0 ;
double *arg3 = (double *) 0 ;
double *arg4 = (double *) 0 ;
char *arg5 = (char *) 0 ;
int32 arg6 ;
int32 arg7 ;
double *arg8 = (double *) 0 ;
char *arg9 = (char *) 0 ;
int32 *argp6 ;
int32 *argp7 ;
int32 result;
arg1 = (double)jarg1;
arg2 = (double *)jarg2;
arg3 = (double *)jarg3;
arg4 = (double *)jarg4;
arg5 = (char *)jarg5;
argp6 = (int32 *)jarg6;
if (!argp6) {
SWIG_CSharpSetPendingExceptionArgument(SWIG_CSharpArgumentNullException, "Attempt to dereference null int32", 0);
return 0;
}
arg6 = *argp6;
argp7 = (int32 *)jarg7;
if (!argp7) {
SWIG_CSharpSetPendingExceptionArgument(SWIG_CSharpArgumentNullException, "Attempt to dereference null int32", 0);
return 0;
}
arg7 = *argp7;
arg8 = (double *)jarg8;
arg9 = (char *)jarg9;
result = swe_heliacal_ut(arg1,arg2,arg3,arg4,arg5,arg6,arg7,arg8,arg9);
{
int32 * resultptr = (int32 *) malloc(sizeof(int32));
memmove(resultptr, &result, sizeof(int32));
jresult = resultptr;
}
return jresult;
}

As far as I recall the @xxx is an offset value used by the linker/loader and is not actually part of the exported name. Try linking with the undecorated name to check that it works correctly.

Hi everybody i've started learning C++ and i wanna know what are the things that we can do with ? i mean real projects 
thks

You can do more or less anything with C++, there are very few limitations. I would suggest you spend some time browsing the articles[^] here on CodeProject to see some interesting examples.

Hi
I have created my own CWnd Class named CShell my problem is OnChar function not called
here with i have attached the code sample
#pragma once
// CShell
class CShell : public CWnd
{
DECLARE_DYNAMIC(CShell)
public:
CShell();
virtual ~CShell();
protected:
DECLARE_MESSAGE_MAP()
public:
afx_msg void OnPaint();
afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
private:
CStringArray m_shellText;
int m_cxChar,m_cyChar,m_cxCaps;
TEXTMETRIC m_tm;
public:
afx_msg void OnChar(UINT nChar, UINT nRepCnt, UINT nFlags);
};
// Shell.cpp : implementation file
//
#include "stdafx.h"
#include "CommandLine.h"
#include "Shell.h"
// CShell
IMPLEMENT_DYNAMIC(CShell, CWnd)
CShell::CShell()
{}
CShell::~CShell()
{}
BEGIN_MESSAGE_MAP(CShell, CWnd)
ON_WM_CHAR()
END_MESSAGE_MAP()
void CShell::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
{
// TODO: Add your message handler code here and/or call default
//CWnd::OnChar(nChar, nRepCnt, nFlags);
}

I see I did have the 'treat as text' checked, though it worked as link in the 'preview message' so I thought I'd got it right.
Thanks.

Dear All,
I am using VS2008 express edition. I would like to add .txt file as resource file into the VS project and furthur read this file as a normal file read.
I was able to add the file as resource file. But don't know how to read this file
i just used :
ifstream fileread;
fileread.open("test.txt");
but this doesn't seem to work
Do u have any suggestions how this can be accomplised.
BR,
Raghu

This is not the correct forum. But anyway...
First get a pointer to the resource.
You can get this by calling the following APIs in order -
FindResource
LoadResource
LockResource
Next use the pointer returned by LockResource in a call to CopyMemory or memcpy/memcpy_s.

I want to return a reference to a subvector of an std::vector like boost::ublas's subrange method does. For example:
...
std::vector<int> v1(100, 1), v2(10, 2);
subrange( v1, 0 /*start/, 10 /*end*/) = v2;
...
will change the first 10 element of v1 to be those of v2. Another call like
v2 = subrange( v1, 50 /*start/, 60 /*end*/);
will fill up v2 with values from v1's 50th to 59th elements.
How to implement method subrange? Thanks a lot.

Hello,
I apologize if this is the incorrect site to post, but I could not find any topics that related the above discussion.
Could you please let me know, if any differences at all between the above commands.
We have a program, that needs to be running constantly with a pause of 3 minutes before the next run.
We have 13 such programs.
So, we are considering performance a big part.
Thanks again.

I wondered if anyone can enlighten me on this. I can't seem to find anything from Microsoft that definitely states that AES 256 bit encryption can be enabled under Windows XPe. Does anyone know if this is possible, or am I stuck with triple des? If anyone can shed any light, point me to some articles, etc. Specifically, I need to do some column level AES 256 encryption using SQL Server 2005. DES works fine, but I get an error that AES is not supported.
