Re: How to get a local printer status?

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.

"Normal is getting dressed in clothes that you buy for work and driving through traffic in a car that you are still paying for, in order to get to the job you need to pay for the clothes and the car and the house you leave vacant all day so you can afford to live in it." - Ellen Goodman

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 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.

Cannot get reference to Locked screen when the system is in RDP state

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 />

   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!

Compiles with VC6. Is this still available?

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 C2143: syntax error : missing ';' before '('<br />
1>f:\copy of dmm\win32\include\dmpluginlibrarydefs.h(682) : warning C4346: 'From::token_type' : dependent name is not a type<br />

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

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.

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?

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.

It's another SDK for compiling scripts into .dll to improve execution time.

DavidCrow wrote:

is the VC6 compiler/IDE available.

Because I got the code to compile with no problems in VC6 and the resulting .dll worked fine. And it seems too much hassle to
get the code to work with a more recent compiler.

you can still find copies on eBay (i got one from there, a few years back)

MS keeps making the compiler more standards-compliant.

it's probably easiest to just fix the code. most of the compiler changes are pretty easy to accommodate.

So what's the problem exactly? Confused | :confused:

the code's output is not looking right in notepad, it just print out a long list of numbers..

Which means what exactly? A long list like:

1 2 3 4 5 6 ...

or

1
2
3
4
5
6
...

Your code appears to write 2¹⁵ lines to the file. Is that what you are seeing?

Provide an example of what you are seeing vs. what you are wanting.

it outputs like:
250 34 34
249 34 35
248 34 36
247 34 37

instead of like:
240 45 0 239 45 0 239 45 1 238 45 1 237 46 1 236 46 1 236 46 2 235 46 2 234 46 2 234 46 2 233 46 3 232 46 3 231 47 3 231 47 3 230 47 4 229 47 4 228 47 4 228 47 4 227 47 5 226 47 5 226 48 5 225 48 6 224 48 6 223 48 6 223 48 6 222 48 7 221 48 7 221 48 7 220 49 7 219 49 8 218 49 8 218 49 8 217 49 8 216 49 9 215 49 9 215 50 9 214 50 9 213 50 10 213 50 10 212 50 10 211 50 11 210 50

You deleted your post. Not much can be done for that sort of mentality. Good luck with your project.
