further...I would anticipate that you might need to interface to the legacy C code from the C++ code. In the C++ code mark the legacy C headers as C code:
extern int stableAPI(int icount);
extern "C" {
#include "legacycode.h"
}
void CppFunction()
{
std::vector <int> vNumbers;
vNumbers.push(1);
vNumbers.push(2);
vNumbers.push(3);
int iResult = stableAPI(vNumbers.size());
}
When you have to pass information to the legacy code, it can only pass C types; don't pass pointers to C++ types. Be sure you know who owns what memory. A simple solution is to write copy API's in the C++ code that are called by the legacy C code in the same way that windows API's do. You pass in a pointer to a buffer with a pointer to a length that is the size of the buffer. If the buffer is too small the function returns an error and set the length to the size needed:
int CopyCppData(char * pszBuffer, int * ilength);

Hi,
I am getting error while compling my C++ code when I am using SafeArrayGetElement method in Unix.It is complining successfully in Windows.
Is there any equalent method for SafeArrayGetElement for getting each element from safearray in Unix enviroment?
Thanks in Advance

AFAIK the aren't SafeArrays at all in UNIX.

What are you trying to "lock"? Are you trying to prevent simultaneous access to the file?
If so, between separate processes? Threads of the same process?

Hi..
I am trying to lock a log file...
I am creating a log file...which will be opened once...
i will write log errors to that....
i want to use locking so that no one else can write to that log file...

Open the file in a share mode that doesn't allow writing (e.g. pass 0 as share
mode parameter to CreateFile()).

If you are trying to have a log file that can be read by other apps while you are still running, you can set the sharing permissions (allowing read access) correctly when opening/creating the file.
Note: I believe that some common Windows apps, like Notepad and Wordpad/Write, will try to open file with write/exclusive access, which is why some apps can open a file you are using while Notepad cannot.
I previously had to have a log file that was readily readable. Even though it sounds like a lot of overhead, I ended up opening/writing/closing the file each time I had to log something. Given that I only wrote log events between 1-4 times a second, the overhead (while measurable on the microsecond and clock tick level) was acceptable.
You likely would not want to do that if the log file is remote...
Peace!

Hi,
I have a trouble to get the local printer status. I simply want to check whether a printer is connected to my PC or not.
I used the GetPrinter() to retrieve the PRINTER_INFO_2. But the "Status" field always returns 0 whether the printer is connected or not, whether before or after sending the prints.
Can you help me with that? I am using VC++6.0 in WinXP.
Thanks a lot,
Stanley

Odd, since none of the PRINTER_STATUS_xxx values resolves to 0. Are you sure that GetPrinter() is returning a non-zero value?
You might also consider using the Win32_Printer WMI class.

Yes, the GetPrinter() returns a non-zero value and the "Status" field is 0 somehow although it is not among any of the defined PRINTER_STATUS_xxx values. Some related posts pointed to the lack of a bidirection communication feature of the printer. I am not sure and need check with the manufacturer.
The Win32_Printer WMI class sounds a great suggestion to me. I will try it since it contains a "PrinterStatus" property.
Thanks for the help!

I must install which Windows Components before I install Visual Stduio 2003?
I insert the CD1 of VS2003, it always tell me to restart computer.

I don't remember the 2003 install needing any prerequisite installations that
it didn't install itself.
Maybe the .NET framework 1.1? Check the readme.

Read the senario first in order to understand the problem
I had compile service in order to logon to windows remotely. I am achieving this by opening a reference to winst0 desktop and getting the reference of the login windows and set the username and password.
There are 3 states in which the user name and password can be passed.
1. when the system is at logged out state i.e no user has logged on (my service is working in this state)
2. when the system is at locked out state by pressing ctrl+alt+delete and selecting lock option (my service is working in this state also)
3. when the target system is accessed via RDP, the target computer goes into locked state, this is where is am facing problem.
I cannot get the reference to the locked window.
Can any one please let me know what is the problem and how do i get the problem solved.
here is the code
HWINSTA hWinStaUser = OpenWindowStation("WinSta0", FALSE, MAXIMUM_ALLOWED);<br />
if(SetProcessWindowStation(hWinStaUser))<br />

It could be that the visible desktop is not the secure (Winlogon) desktop. Have you tried having your service enumerate the available desktops (and even looking for the dialog on a Desktop as it is enumerated)?
It might be that RDP handles (interactive) Desktops differently than the standard winstation because of how Terminal Services works.
Have you also tried getting the Winlogon desktop when no-one is logged in and an RDP session starts? (Just to complete your tests.)
Peace!

Hello,
I've downloaded an SDK an am able to get the code to compile with VC6 no problem but
when I use Express Edition 2008/2005 I get all sorts of compiler/linker errors. The
problem is I only have access to VC6 in work and would like to have a copy for myself.
Is it still available? or is there a way to get the Express Editions to use the VC6
compiler? Searching for this hasn't turned up anything
Also: Why would something compile with older versions and not newer ones?
Thanks

All the errors about using 'template<>' i can solve by editing the header as advised in the error message.
I don't really know how to follow this error:

1>f:\copy of dmm\win32\include\dmpluginlibrarydefs.h(682) : error C2061: syntax error : identifier 'token_type'
which realte to this part of the header:
To::ret_token_type operator()( _GATAN_COMPILER_TYPENAME From::token_type tok )<br />
{ return reinterpret_cast<to::ret_token_type>( dm_env->convert_object( reinterpret_cast<dm_objecttoken>(tok), from_desc, to_desc ) ); }</dm_objecttoken></to::ret_token_type>
I did put 'token_type' and 'typename' in somewhere yesterday and solved them but i don't remember how.
Anyway once I got past these errors I ran in to linker errors.
Thanks

Did you try to prefix token_type with the typename keyword, as suggested?

Hi CPallini,
Yes I have sorted all the previous errors with the suggestions. I wanted to show them in case there was
something i could do with the compile options to get rid of these errors. (I thought I could ask the compiler
to be less strict. Since i got the same thing to compile first time with VC6).
Here's where i'm at now.
Linker errors: (the project was set up so that the linker has the path of the library)
Do you know what the weird combination of symbols mean? such as: (??0bad_cast@std@@QAE@PBD@Z)

It is C++ name decoration (or mangling) see, for instance [^].
Regarding the linker errors, perhaps this page [^] may help.

This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong.

Thanks very much for the help. I'll take a look at those links.
Thanks

The Platform SDK or some other one?

Is what still available?
Ylno wrote: or is there a way to get the Express Editions to use the VC6
compiler?
This makes no sense. Why would you want a new compiler/IDE to use an old compiler?
Ylno wrote: Also: Why would something compile with older versions and not newer ones?
Because the new compilers are more strict in adhereing to the C++ standards.
