Use GetSystemMetrics(index), where index can be

    SM_CXSCREEN,
    SM_CYSCREEN,
    SM_CXFULLSCREEN,
    SM_CYFULLSCREEN

This will give you the resolution/size of largest window (see docs).

Oops, I do hope that the robotic alarm is taking it's commands as
characters from cin and not cout :-)

Hi Daniel

I have 
#include <iostream>
and that should be enough since it #includes <istream> and <ostream>.

I also 
use namespace std;

The strange thing is that it started when I downloaded Dev-cpp v4.9.7.3=
 with MinGW/gcc 3.2.
Previously released dev-cpp combined with a separately downloaded MingGW3.2=
 did'nt make this error to occour.

cout and cin are usually used for simple DOS based programs
it's basically C for console, CIN = console in, (ie keyboard, what u type into command prompt)
and COUT = console OUT (what is OUTput from the console/command)

Hi again list. 
I posted the following a few days ago. I didn't get any answers :-(. If=
 this is because you can't help me or some with the knowledge missed the=
 post, I don't know. Therefore I give it another try...

/J=F6rgen

*** OLD POST ***
Hi

The following code 

void writeToFile(char* filename, vector<hashItem_rowCol*>& hashTable){
  ofstream ofile(filename);
 
  for(int i=3D0;i<hashTable.size();i++){
    if(hashTable[i] !=3D NULL){

      ...
   
    }
  }
}

produces the following error

Pattern_Creator.cpp:1555: variable `std::ofstream ofile' has initializer=
 but incomplete type

1) What does this error mean?
2) How do I correct it? 

Any clues?

regards,
J=F6rgenr

I have noticed that too, and after I took a look at the exe, I found=20

Sorry for the late reply, but I'm having the same error. The version with
2.95.3 gcc does the work, so this just seems like a serious bug to me :)

Just as long as you are aware that strtod, strtof, strtol, ... can perform
tricks that sscanf can not. sscanf works reasonable for processing a
configuration file with known contents. It doesn't work when parsing a
language, or an expression, since you don't know the contents of the line
until you have parsed it.

Hello again!

 From some docs:
"
ignore( int nCount, delimiter );

Where nCount is the amount of characters to be ignored and delimiter is 
what its name says. It can be EOF if you want to stop at the end of the 
file. This way, this function is the same as seekg(). But it can also be 
'\n' for example, which will stop on the first new line.
"

So it will ignore the next nCount characters and stop if the read 
character is delimiter.

Hi Santiago,
 Yeah , it should be like that , of course .
  Thanks for pointing that out. I've been using that prog for some time 
.I think the reason it worked for me was that I wasn't doing anymore 
allocation after that line , and the line was near the end of code .So 
there  was more headspace available  for the bigger struct .
Thanks again ,
Regards,
Rahul .

sscanf can convert one or multiplie parameters from a text string into

of what sscanf considers white characters etc. And in case of a conversion
problem, it isn't easy to point exactly at the failing character.

With strtod, you get a pointer to the first un-processed character of your
input string. For a parser, the normal action is to process characters one
at a time - that means that strotod is never called unless the parser
knows that the first character is the start of a number, i.e. the next
character to process is 0-9 or a decimal separator (. or , depending
on locale). Uppon return of atrtod, the parser may then immediately
continue parsing at the endptr position.

Hi all,

Since downloading the Critical Update and all that good stuff using Vupdate
yesterday, Vupdate now tells me that "Your Dev-Cpp config file is missing
the $ROOT field in its [VUPDATE] section..." and it won't work anymore.

Any ideas?

Haha. Your question was actually a very good one. It took me at least 20 
mins to figure out, but I have found what is the problem.

When you use cin before you use getline, it leaves a newline character 
in the input (the console) and when getline is called it reads that 
newline character and returns with an empty line. To fix this, use the 
ignore function after you use cin and before you call getline:

cin.ignore(10,'\n'); // skip 10 chars until reaches '\n'

This will ignore all the '\n' characters so that getline will work properly.

Here is where to put it exactly:

The only difference in your code compared to mine is this.

Your code:
  if(bind(sock,(struct sockaddr*)&server,sizeof(struct sockaddr))==-1)

My code:
  if(bind(sock,(struct sockaddr*)&server,sizeof(server))==-1)

Hope it helps...

They always say "There are no such thing as stupid questions, just
plenty of inquisitive idiots" but here it goes........

I'm still a complete beginner in C++ and programming in general. I've
written yet another silly little code to get used to the syntax and
arrays. I was going to use parallel arrays but so far have only tried to
use a single array. Something is causing me problems. The "while" loop
ignored the first "index" value of 0 and jumped to the second value of 1
before executing the commands within that loop. I've tried using a "for"
loop with no success either.

Can someone try this out and tell me what I've missed? Much
appreciated...........

============================================
#include <iostream>
#include <string>

#define TAB '\t'

main()
{
    using namespace std;
    
    //Define how many planets there are
    int MAX;
    cout << "Enter the number of planets: ";
    cin >> MAX;
    //Define max length of planet names
    int LENGTH;
    cout << "Enter max length of planet names: ";
    cin >> LENGTH;
    cout <<"There will be " << MAX << " planets" <<endl;
    cout << "Each will be " << LENGTH << " chars long" <<endl;
    LENGTH = LENGTH + 1;
    
    //Define the 2 arrays, planet names and distances
    char name[LENGTH];
    char planet[MAX][LENGTH];
    int distance[MAX];
    int DIST;
    int index = 0;
    
    while (index < MAX)
    {
        cout << index << endl; //I put this in here to show that it
skipped the value 0
        cin.getline(name,LENGTH);
        strcpy(planet[index],name);
        index++;
    }
    
    index = 0;
    
    for (index = 0; index < MAX; index++)
    {
        cout << endl << planet[index] << endl;
