I see at least three separate issues here. What exactly are you having trouble with:
1) opening a file
2) responding to a button click
3) reading from an edit control
Be specific with your request(s) and you'll get way more help.

you can use (CFile /CArchive) to open file and use SetWindowText to set filename in editbox
and for change color from editbox use OnCtlColor.

One way is to Create a strucure as
struct numberStruct{
int m_iX;
int m_iY;
};
Now while writing and reading using FILE object write/read the complete structure using fwrite and fread.
Somethings seem HARD to do, until we know how to do them.

This won't work at all: you will write binary data to the file which is not what the OP wanted to do.

it wont work. he has a text file, not a binary one...
and your method doesn't take in account the space delimiters between the values in one line...
however, the idea of the struct can be a good memory representation, once the file is read, to load its content in memory

Try this:
---------
#include <iostream>
#include <fstream>
#include <string>
#include <sstream>
int main(int argc, char* argv[])
{
using namespace std;
// Open the file.
ifstream fs("C:\\a.txt");
if (!fs)
{
cerr << "Couldn't open file!" << endl;
return 1;
}
// Read in the lines and sum them.
string line;
while ( getline(fs, line) ) // Get a line.
{
// Sum each number in this line.
int num;
int sum = 0;
istringstream iss(line);
while ( iss>>num )
{
sum += num;
}
// Output the result.
cout << "Total: " << sum << endl;
}
return 0;
}

For starters:
int n1, n2;
FILE *pFile = fopen(..., "rt");
while (! feof(pFile))
{
fscanf("%d %d", &n1, &n2);
}
fclose(pFile);

Here is a very basic solution:
<br />
void main()<br />
{<br />
vector<int> Col1, Col2;<br />
ifstream fin("mytext.txt");<br />
while (!fin.eof())<br />
{<br />
int c1, c2;<br />
fin >> c1 >> c2;<br />
Col1.push_back(c1);<br />
Col2.push_back(c2);<br />
if (fin.eof())<br />
{<br />
break;<br />
}<br />
}<br />
<br />
int Column1Total = accumulate(Col1.begin(), Col1.end(), 0, add<int>()); <br />
int Column2Total = accumulate(Col2.begin(), Col2.end(), 0, add<int>());<br />
}

Please can somebody help me. I am just not getting it.

Having you considered using the CButton::Create() method? What code do you have that is not working?

This is what I have done:
void CBudget::CreateRadioButtons()<br />
{<br />
CButton newRadio;<br />
CRect rect;<br />
<br />
#define IDD_NEWR1 0x1234<br />
<br />
rect.bottom=150;<br />
rect.top=100;<br />
rect.left=100;<br />
rect.right=250;<br />
<br />
newRadio.Create(_T("Home"), WS_CHILD | WS_VISIBLE | WS_TABSTOP | BS_RADIOBUTTON, rect, this, IDD_NEWR1);<br />
but nothing showsup. I have called
CreateRadioButtons() in OnInitDialog()

I think you should move the CButton newRadio; declaration to the class body. Make it as a data member of CBudget. Otherwise your control is deleted after finishing the CreateRadioButtons function.

Another solution is to put your controls in the dialog using Dialog editor, making them invisible. When you need to show them, just make visible. In this way is easier to define event handlers for your controls.

Ah yes! It worked. Thanks.
Now, if I create 3 buttons, how do set then as a group. i.e how do I use them? How do I get which radio button has been selected.

Use the WS_GROUP style for the first one.

Add Handler's for them in message map section
ON_BN_CLICKED(ID_RADBUTTON ,OnRadioClicked) // Defined ID_RADBUTTON
//in the header file
afx_msg void OnRadioClicked();
//and in the cpp file
void CCheck1Dlg::OnRadioClicked(){
//Some COde
}

The problem is I do now know how many will be needed. It dependes upon how many budget entries a user makes.

Can I not create another radio button using the same CButton object, newRadio?

Yes, but newRadio will need to be a pointer.

A CButton object is for one radio button. If you need more, define another CButton data member.
In case of variable number, you can define a dynamic collection of such objects. For instance, you can try CTypedPtrArray< CObArray, CButton * >.
You have to create new buttons with new CButton, then call Create, and then add to collection with Add. Do not forget to delete the unneded buttons with delete.

Oh no I just dont have the time to figure out that. I guess I use good'ol combo box or a list box instead!!
Thanks a lot for the help everybody. I will definitly try it out later, and maybe post an article;)

Move the line CButton newRadio to the header file Budget.h
What i think is that you are going to create these buttons dynamically and more than once. So it would be better for you to change the function definition to
CreateRadioButton(int,int,int,int);// Specifying where to place the buttons.
