When you log into Vista, your application crashes? If so, please explain the connection.

Was the application build with vs2003 ever ran on Vista ? or did you upgrade both OS and compiler at the same time ?

Is it possible your application is trying to access registry values without proper permissions ?

Dear Experts,

i could not able to build a following visual c++ code.can any one help me?

It shows can not open activeds.h

#define _UNICODE
#pragma comment( lib, "Activeds.lib" )
#pragma comment( lib, "Adsiid.lib" )

#include "stdafx.h"
#include <atlbase.h>
#include <activeds.h>
#include <cstringt.h>
#include <atlstr.h>
#include <comdef.h>
#include <Iads.h>
#include <Adshlp.h>

int _tmain(int argc, _TCHAR* argv[])
{
HRESULT hr;
IADsContainer *pCont = NULL;
CoInitialize(NULL);
hr = ADsGetObject(L"WinNT://xxx.com/dc1.yyy.xxx.com", IID_IADsContainer, (void**) &pCont );
if ( !SUCCEEDED(hr) ) { return hr;}
_variant_t var;
IEnumVARIANTPtr pEnum;
ADsBuildEnumerator (pCont,&pEnum);
int cnt=0;
ULONG ulFetched = 0L;
_variant_t vChild;

hr = V_DISPATCH(&vChild)->QueryInterface(IID_IADsUser, (void**)&pADs);
if(hr!=S_OK)
break;
BSTR bstrName;
pADs->get_Name(&bstrName);
CString csName=bstrName;
SysFreeString(bstrName);
printf("%s\n",csName);
pADs->Release();
pADs = NULL;

}

// Cleanup.
if ( pCont )
{

}

return 0;

So does it exist? It should be part of the Platform SDK.

you are using the following header files
#include "stdafx.h"
#include <atlbase.h>
#include <activeds.h>
#include <cstringt.h>
#include <atlstr.h>
#include <comdef.h>
#include <Iads.h>
#include <Adshlp.h>

Is it a small project?
does your application contains the activeds.h?

If your project does not contain any file,then only you will get this problem..First you look for this header file whether it is there in your appliation or not..?

Capturing printed data

Hi, I need to capture data (TEXT only) which is printed on a specified printer (no matter what is the type of printer).

I'm thinking about printer driver which will redirect print jobs to a real printer but this seems to be too complex.

May be nother solution exists (does it?). Could anyone tell me how can this be done in C++ or where can I read about this?

Thanks in advance

I don't think this is possible, either with C++ or any other language. Modern print functions do more than just write strings of text line by line to the device. They have to manage page positioning, headers and footers, etc.

Perhaps if you explain more of what you are trying to achieve we could offer some suggestions.

First of all I need to capture data which is going to be printed (no matter which format).

Getting TEXT only data is next step of this task.

Main task is to catch data which goes from a POS system to printer(usually TEXT only printer).

Thanks in advance.

This sounds quite a complex project. The only way I know of capturing all data, is by creating a printer driver program which can be used in place of a physical printer. This program will need to interpret all the print commands in order to layout the actual text on some form of virtual page. Finally the text information will need to be extracted and reformatted according to your requirements.

The only tools I'm aware of that may help are the Ghostscript tools found here[^].

What's your real problem that you're wanting to solve by intercepting text sent to the printer (which, I'll tell you now, is likely to be nigh on impossible, and incredibly fragile if you diod get something working)?

Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

POS systems - Text capture is quite common. Usually done via hardware by tapping serial printer's RX line and reading the ASCII bytes. In this case he wants to capture it at a software level not a hardware level. Since he's using the Generic Text Only driver, there is no graphics involved in the printing process - everything is ASCII. Text capture is done for security reasons in order to show / prove the proper change has been returned or that the operator actually puts the cash in the till and not in his pocket (text capture is usually superimposed over live video of the cashier.)

If the ProgID does not exist on the machine (i.e., MSXML has not been installed), CreateInstance() is obviously going to fail, hence why I asked if it existed.
