Why you want to assign the variable for radio?

You can get a handle to it like this GetDlgItem(IDC_RADIO);

Can someone provide some code that shows how to obtain a single character from a CString that could contain upwards of 1024 characters?
I've tried several methods, but none have worked.
Example:
CString str = _T("Can someone provide some code that shows how to obtain a single character from a CString that could contain upwards of 1024 characters? I've tried several methods, but none have worked.");

TCHAR c = str.GetAt(0);
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Whooaaa there cowboy...you did that without using GetBuffer()? Now you're just talkin' crazy

oh, sorry...
TCHAR a = *(str.GetBuffer(10)+5);

Mark, Can you explain what you are talking about? Sounds like something I should already know; but I don't. What I am doing is reading back a CStdioFile that I have save data into (collected from User input in dialogs). Some of this data is float numbers, hence the need to check each character in the CString. I have to use atoi(char) to convert the character which doesn't accept a TCHAR.

You can ignore this off topic discussion with cpallini...
It's a running joke about CString's overly misused GetBuffer() method

Mark,
chrs[1] = _T("\0"); // must be NULL terminated!
I get this error: " error C2440: '=' : cannot convert from 'const char [2]' to 'TCHAR'"
any ideas why?

I used the wrong quotes, sorry!
That should be single quotes for a single character...
chrs[1] = _T('\0'); // must be NULL terminated!

Mark,
I'm getting a compiler error C1001; even after commenting out all the new code in the function. I tried shutting down the switches as help suggest. That doesn't work either. Any ideas?

What's the error and what's the code involved?

I solved the problem by deleting the debug obj file previously created. works now!

I tried that. Here's my code:
TCHAR chr;
int ch = 0;
chr = str.GetAt(0);
ch += atoi(chr);// ERROR HERE: when I try to convert it to int using atoi(chr)
I get this error: "Error 1 error C2664: 'atoi' : cannot convert parameter 1 from 'TCHAR' to 'const char *' c:\users\larry a mills sr\documents\visual studio 2008\projects\logit\logit\editlog.cpp"

atoi() takes a const char * as an argument, not a TCHAR.
What are you trying to do? Convert the TCHAR you extracted to an int?
If so, you should be using generic text mapped functions, not functions like
atoi() that only work with one character type.
Generic text mapped functions will work for Unicode or non-Unicode builds.
In a Unicode build, a TCHAR is a wchar_t
In a non-Unicode build, a TCHAR is a char
Generic-Text Mappings in Tchar.h[^]
CString is also a generic text class by the way - it's internal character type is based on the Unicode build setting.
Also, you need to pass the correct type of argument to functions.
Maybe something like this:
TCHAR chrs[2];
int ch = 0;
chrs[0] = str.GetAt(0);
chrs[1] = _T("\0");
ch += _tstoi(chrs);

Hey Mark, what about
int ch = str.GetAt(0) - _T('0');
?

Can anyone help me get on the right track with this program. I am having a hell of a time with this. I have to use De Morgans Law to show the original expression and the new expression:
a) ! ( x < 5 ) && ! ( y >= 7)
b) ! ( a == b ) || ! ( g != 5)
c) ! ( (x <= 8 ) && ( y > 4 ) )
d) ! ( (i > 4 ) || ( j <= 6 ) )
I know how to put it into De Morgans Law I just don't understand how to put it into a source code in C++
