I need to read ascii coming from my printer. It needs to be something
like this:
System.IntPtr lhPrinter=new System.IntPtr() ;
DOCINFO di = new DOCINFO();
int pcWritten=0;
int pcRead=0;
string st1;
if(readResult = (! PrintDirect.Rea dPrinter(
lhPrinter,st1,s t1.Length,ref pcRead) ))
{
listBox2.Items. Add(st1);
}
public class PrintDirect: Form1
{
[ DllImport( "winspool.drv", CharSet=CharSet .Ansi,ExactSpel ling=true,
CallingConventi on=CallingConve ntion.StdCall)]
public static extern bool ReadPrinter(Int Ptr hPrinter,string data,
int buf,ref int pcRead);
Am I even close?
Thanks,

You should use OpenPrinter to get the printer handle. And the second
parameter to ReadPrinter should be a StringBuilder if it's an output
string buffer.

Mattias,
I looked at some stringbuilder samples and just don't get it. I think I
need more info from winspool.drv... it's really hard to find out ANYTHING
from Microsoft.
Any help is appreciated.
Thanks,

Not sure where you are looking, MSDN - .NET Framework Developer's Guide
contains hundred of samples, start reading here: Using the StringBuilder
Class
And no, you don't need winspoll.drv.

Hi,
I'm trying to build my custom Printer Dialog box.
The following code is supposed to Pop up the printer properties form and
edit the PrinterSettings.
My problem is that I'm able to show the Printer Properties form but I'm
unable to write back the settings to my PrinterSettings
It either crash with a null reference exception or my application freeze
completly.

The WritePrinter() is working. I know this ReadPrinter()
implementation isn't correct because it never reads into "reaDstrinG"
buffer from the printer...But, I'm sure one of you Guru's do know how I
can make this work (and any help is appreciated):
string reaDstrinG = "";
int pcRead = 0;
for (int i = 0; i < 23; i++)
{
PrintDirect.ReadPrinter(lhPrinter,reaDstrinG,100,ref pcRead);

Hi Everyone,
I would like to use some of the Win32 printer functions in C# but they are
in Winspool.lib. I was hoping that there is a way to do this without writing
a dll in C++ and importing the functions. So, is there a way?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
