May be you could have an overloaded constructor for your second dialog, which accepts a pointer to a string. 
Step 1: In your first dialog:
#include "NewDlg.h"
CString cst;
CNewDlg cnd(&cst);
if(cnd.DoModal() == IDOK);
AfxMessageBox(cst);
Step 2: Overloaded constructor of the new dialog:
CNewDlg::CNewDlg(CString *str, CWnd *pParent):
CDialog(CNewDlg::IDD, pParent), m_str(str)
{
}
Step 3: In the OnOK() handler of the second dialog:
CString szVal;
m_edit.GetWindowText(szVal);
*m_str = szVal;
CDialog::OnOK();
A crude way, but it works.

The solution is not as straight forward as seems to be. My first approach was to handle WM_SETFOCUS, but it will not work. But I have faced a similar situation my requirement was different. So let me give you the solution, just override OnCommand & check for notification code of WPARAM.

hi
this is my code ..its working good in 3digit sorting algorithm.
#define next(i) ((i) < 5 ? (i) + 1 : 1)
#define previous(i) ((i) > 1 ? (i) - 1 : 1)
int main()
{
unsigned long i, aux, j, cnt;
for (i=1 ; i<6 ; i++)
{
for (aux = next(i) ; aux != previous(i) ; aux = next(aux))
{
cout << i << aux << next(aux) << endl;
}
}
return 0;
}
But, i replaced 5 into 100 ..its showing wrong sorting why?
#define next(i) ((i) < 100 ? (i) + 1 : 1)
#define previous(i) ((i) > 1 ? (i) - 1 : 1)
int main()
{
unsigned long i, aux, j, cnt;
for (i=1 ; i<101 ; i++)
{
for (aux = next(i) ; aux != previous(i) ; aux = next(aux))
{
cout << i << aux << next(aux) << endl;
}
}
return 0;
}
Thanks and Regards

That is because you didn't try to get into the code you were given yesterday (that works with 3 digits)  . It would be better for you to understand the algorithm for 3 digits before you move ahead to implement the second one. BTW what happens when you try and debug your new code?
And the error displayed is...........................

Use netstat.
netstat -p TCP /b to list all opened TCP ports along with the exe's name.
or
see telnet

Hello everyone,
I have successfully setup remote debugger for Visual Studio. My question is about how it works internally to match remote execution binary to source codes on host machine. Any points for how it does the match? Do I need to deploy the same PDB to both remote and host machine?
thanks in advance,
George

Because none of those make sense used on a class member.

but when we write like
class a
{
int i;
};
then obviously by default data type of i is auto int
my question is why compiler don't accept this,and why none of those make sense as you wrote.
if u have any link related to this question please send me
thank u in advance

No, it isn't. i is a class member.
auto variables have a local lifetime - the lifetime of i is determined by the
lifetime of the object it is in.
register - same thing. You've only declared i. Until there's an instance of an "a" object,
i doesn't exist. How, then, can you give i a storage specifier?
extern? Makes NO sense. How can a member of an object be somewhere else - some external location?

The code is written in C# so it's better to use Managed code itself to get teh required functionality from this library. Otherwise you will have to port the code to C++.
There are some tweaks to call C# code from native C++.
Exposing .NET Components to COM[^]
Calling C# code from C++[^]
.NET COM IOP[^]
Anyway I've never tried this out. Please check it.

I have a dialog based application.I use a text box in it.what i want is write the details from that text box into a text file.
when i wrote the code ,the data written into the file was as follows..??a??????ý????ý
My code is,
CString str;<br />
GetDlgItemText(IDC_EDIT1,str);<br />
fstream f;<br />
f.open("C:\\myfile.txt",ios::app);<br />
f.write((LPCTSTR)str,10);<br />
f.close();<br />
|
|
|
|
|
str is uninitialized and therefore the value displayed in the edit box is a garbage value.
Initialize the str to something meaningful.

initialized it to spaces.-> CStraing str="";
But it still doesn't work.
|
|
|
|
|
CString str="";
GetDlgItemText(IDC_EDIT1,str);
fstream f;
f.open("C:\\myfile.txt",ios::out|ios::app);
f.write((LPCTSTR)str,str.GetLength ());
f.close();
This will help

yes,now that works.
what if i want to write the new value in the edit box in newline.now all the data are written in single line.

Append \r\n in the string where you want a line break

I think this statement makes the problem. give proper length of the source buffer. If the string length less than 10, this problem may occur.
Please try with this.
f.write((LPCTSTR)str,str.GetLength());

Hi,
I followed this link for embedding manifest in the exe.
http://msdn.microsoft.com/en-us/library/bb756929.aspx
I could see RT_MANIFEST markup in the exe(using resourcehacker).
But yesterday when i rebuilt my application (both in vista and windows 2003 server) i am not able to see RT_MANIFEST markup in the exe. Instead i saw a number 24 under that my manifest file is there.
Are some settings changed? I am not able to figure it out. Can any one help me?
Regards
