By default only the Close button is enabled. You can add the Minimize Box or Maximize Box styles to add the respective buttons to the caption bar.

Yes. You can use TAPI to place a call (to the other modem), and then transfer data between the modems.
And use TAPI to wait for a call, answer it and then transfer data between the modems.

The input is an int with no spaces, how would i get it to do this, 111,

int n=0;
int decimal=0;

cin>>binary;
if(binary!='/n'){
decimal=binary*2^n
n++}
The thing is it has to affect only one digit of the int at a time, and I'm not allowed to use arrays.
Any Ideas on how this could be achieved.

binary=111
decimal=(1*2^0)+(1*2^1)+(1*2^2)=7

like that but for 32 bits.

any ideas are appreciated, thx.

Is this some kind of assignment to you?
Anyway's here's the code:

#include "math.h"
#include "iostream"
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
	cout<<"Enter a number in the binary format:"<<endl;
	unsigned int num;
	cin>>num;
	int t=0;
	int result=0;
	int j=0;
	while(num!=0)
	{
		t=num%10;
		result+=t*pow(2,j);
		num=num/10;
		j++;
	}
	cout<<"The equivalent of the binary number is :"<<result;
	return 0;
}

The code just shows how this can be done.Modify the code to meet your needs.

Somethings seem HARD to do, until we know how to do them.

isn'y you need some thing like this

while(binary!=0)
    {
        int nTmp=binary%10;
        binary=binary/10;
        decimal+=nTmp*pow(2,n);
            n++;

    }

In addition to the above posts, an alternative to pow(2, n ) is the bitwise left shift operator ( 1 << n ).

Are you simply wanting to convert from base-2 to base-10? If so, just use strtol().

It will always update by last record.
Do you have any suggestion

I think this line is the problem. You are always concatenating to an existing string.

I guess it should be

m_MainEdit_EUR = <code>m_MainEdit_EUR +</code> Market +"," + Bid +","+ b +","+ Ask +","+ c +","+ High +","+ Low +","+ d +","+ Timestamp+"\n";

You are appending to the previous buffer that you had. You should clear it first and then assign.

Yeah it will not work if Market is itself a pointer...

Try this...

m_MainEdit_EUR = "";
m_MainEdit_EUR = m_MainEdit_EUR + Market +"," + Bid +","+ b +","+ Ask +","+ c +","+ High +","+ Low +","+ d +","+ Timestamp+"\n";

This will work.
