Rather than opening an acc in forum this simple thing can be found from google itself. For a starting of vc++ dialog based application see this.

Well, your first step is creating the dialog App.
The second - read text file. I'd suggest using MFC classes CString to store the text and CStdioFile to read in.

After you'll be complete these steps we'll be going on with the next task ("nterfacing with hardware" which is not clear for me yet)

First I have to write some thing in text file then read that file and load to List Box..

// This button will input the Data into the File

void Cfile1Dlg::OnClickedBtnExcute()
{
// TODO: Add your control notification handler code here
UpdateData(TRUE);
fout.open("test.txt");
int temp1;
CString str;
str.Format(_T("abc"));


fout << m_Name<< m_Regno<<m_Cellno<< "\n" ;
fout.close();



UpdateData(FALSE);
}


// This buuton will take the data from file and load to Listbox.

void Cfile1Dlg::OnBnClickedOuput()
{
// TODO: Add your control notification handler code here
UpdateData(TRUE);
ifstream fin;
fin.open("test.txt");
int temp1,Numb1;
//m_List1.GetItemData(m_regno);
while (!fin.eof())
{
fin >> temp1;

m_List1.GetItemData(temp1);
m_res=temp1;
}
fin.close();
UpdateData(FALSE);
}

please tell where am doing mistake because its not giving required output.

Looks like you're just guessing. Get a good book.

Off the top of my head,

You don't need the calls to UpdateData

You're using GetItemData in a context that makes no sense. Nothing in your code would add a string to a list box.

You're setting m_res=temp1 each time through your read loop, which makes no sense.

You're using Format instead of just = to assign a string literal to a CString

As VictorN pointed out, CStdioFile makes more sense in an MFC app than streams because it will write directly to a CString and uses MFC Exceptions.

How can I tell you about the "mistake" if you didn't mention what all these identificators (like m_Name, m_Regno, m_Cellno, m_List1, m_res) mean, and what the purpose these lines

int temp1;
CString str;
str.Format(_T("abc"));

are for?

I'm not up on all the latest books, but go to any good book store that has a programming section. There should be several beginners books aimed at Visual Studio 2010 and MFC apps. There's way too much to learn to try to figure it out on your own. I wouldn't even try Google for programming lessons. Most books are over 1,000 pages long for a reason. They'll guide you step by step on what you need to know.

If this is the Express (free) Edition, you won't be able to create MFC apps.
