I tried the same myself but i get a bad error WITH THIS....

int fn(int&a)
{
}
int main(int argc, char* argv[])
{
int abb[10];
fn(abb);
return 0;
}

ERROR:
C:\Windows\Desktop\a\a.cpp(19) : error C2664: 'fn' : cannot convert parameter 1 from 'int [10]' to 'int &'
A reference that is not to 'const' cannot be bound to a non-lvalue

I'm too lazy to look this up from a C++ reference, so I'll let the computer answer:

$ c++decl
Type `help' or `?' for help
c++decl> declare a as reference to array 10 of int
int (&a)[10]
c++decl>

THANX A LOT 'markkuk'. U are a GENIUS (i mean ur computer)

It works. Please please please tell me in which book did u find that syntax.... I was reading C++ from Stroupstrup and in fact... that was a question from the exercises of chapter-5. But i cudnt dig out that particular syntax. thanx.

It is really quite easy to decipher, or create, any simple or complex C/C++ decl, once you know how..

Ever heard of the "right-left rule" ? Again, google is your best friend...

Is there an API function to get Printer feedback from the current job printing?

Thanks

Yes.

The EnumJobs function retrieves information about a specified set of print jobs for a specified printer.

The JOB_INFO_1 structure specifies print-job information such as the job-identifier value, the name of the printer for which the job is spooled, the name of the machine that created the print job, the name of the user that owns the print job, and so on.

That does the trick!

You can use _ttoi or brew your own (more robust) function.

bool convertWideStringToInt
  (wchar_t* wStr,
   int& nInt)
{
  if (wscanf (wStr, _T("%d"), &nInt) == 1)
     return (true);
  return (false);
}

extfloodfill problem ?

kendao30-Jul-04 6:32

ExtFloodFill is used for device context
is there any method to use ExtFloodFill to fill a bitmap ?
thanks...

Re: extfloodfill problem ?

hey, how about blitting the bitmap to that device context and then using the same floodfill function Wink | ;)

Problems with files

Ok, i just im making a binder
and i am using the CreateFile(), ReadFile(), and WriteFile() functions

now it took me long enough to figure out you cant read 28KB file into a buffer and write it all at once

Problem 1
As you should be able to guess im going to split the output by a string (no problem since i already wrote a function for that) but if im reading in segments then well you know it could cut into that string im splitting by

Problem 2
SetFilePointer doesnt seem to be working for me
if i could get this to work i have an idea that m
might (i stress might) solve my problems

Didn't the third parameter of ReadFile work (nNumberOfBytesToRead)?

Jaime

Yes the third parameter of ReadFile has alwase worked. i am sorry but i dont really see what that has to do with either of my problems

Sure you can. I've used these functions before to read in a file 10x larger than that. No problem.

Really. I've read and written larger files in the past. What problems did you encounter?

well at first i just read all of it into one buffer
i defined it like so

char *szBuffer;

and then wrote all of it right after reading
everytime i would get the blue screen of death
then if i returned to windows it would be locked up

i looked at an example on MSDN which read and wrote the data in segments, i have had success doing it this way (no problems, except for the ones i mentioned)

note: when i did this in segments i defined my buffer like
char szBuffer[1024];

could this have been a problem?

if it will help i clean up and post the old code that was wasnt working
