atol() converts an ANSI string to long integer. The function you want is _itoa()(ANSI) or _itow()(UNICODE) or _itot(ANSI and UNICODE) which converts a long integer to a string.
From your previous post I am lead to believe you are using a UNICODE enviroment, so you should either use UNICODE functions (have a 'w' in them instead of an 'a') or use the TCHAR macros.

Same problem as before, you're using an ANSI function (atol) and passing it a Unicode string (CString has a converter to LPCWSTR). Check out The Complete Guide to C++ Strings, Part I - Win32 Character Encodings[^] -- it explains the different string types and functions. You absolutely need to know this for Win32 programming. Just remember that in WinCE, everything is Unicode.

The link to strings has some great information in it, i think, Im too stupid at this point to understand most of what Im reading... Give me some time, Ill figure it out. I had little or no help learning VB, so this is like deja-vu.

error C2065: 'LAnsSum' : undeclared identifier
Hey kewl , I was wondering where you had an Identifier named 'LAnsSum' until I saw that you wrapped 'AnsSum' in a _T() macro. The _T() macro is used to declare a literal string in your code as either an ANSI or UNICODE string. Basicly what it does is use the preprocessor to prepend a 'L' in front of what ever text you run through it.
#ifdef _UNICODE
#define _T(str) L##str
#else
#define _T(str) str
#endif

Okay, now I have:
Ans = N1 + N2;
CString AnsSum;
_itow (Ans, AnsSum, 10);
And getting compiler error:
'_itow' : cannot convert parameter 2 from 'class CString' to 'unsigned short *'
Im still lost... Any suggestions?

This should convert an integer to a CString:
AnsSum.Format("%d", Ans);

Tried:
===========================================================
CString AnsSum;
// _itow (Ans, AnsSum, 10);
AnsSum.Format("%d", Ans);
===========================================================
Compiler/Linker gave:
: error C2664: 'void __cdecl CString::Format(const unsigned short *,...)' : cannot convert parameter 1 from 'char [3]' to 'const unsigned short *'
Guys, Im *very* sorry, Im so new to this I dont even understand the error message. 
Thanks for working with me, I wouldnt blame you all if I got banned from this forum!

Hmm, CString must be a little different between compilers.
Try:
CString AnsSum;<br />
char temp[33];<br />
ltoa(i, temp, 10);<br />
AnsSum = temp;
This works without any headers in VC++ 6.0 but if it doesn't know what ltoa is try [edit] including stdlib.h [/edit]. Don't feel bad about asking questions, simple or complex, we've all got to start somewhere.

I assume you are using UNICODE the error message is saying that the "%d" is in the wrong format for unicode it must be an unsigned short, the _T deals with it

AnsSum.Format(_T("%d"), Ans);
Holy cow Batman! That worked!
Though, I didnt include #include <tchar.h>, may be default part of the IDE for WinCE, dont know..
Yes, I have recently been educated that I am programming for a Unicode environment, the PocketPC IE: WinCE. Though I have not a clue what that means at this point, Ill figure that out later. Now I gotta learn ANSI formats so I can write for the X86 platform! UGGGG!
Now I know why VB is so appealing to newbies! HAHA!
Thanks much for the on target help!

Cool, it looks like I was on the right track when I was trying to help, just haven't dealt with UNICODE before. I'll have to look into the tchar thing.

I used the _T macro, the "correct" way would be to use L("%d")
"Using Generic-Text Mappings"
"Data Type Mappings"
i.e look for _T in the index

hey, I was looking at the tutorial to show fonts in a combo box(http://www.codeproject.com/combobox/fontcombo.asp?forumid=3520&app=50#xxxx). I'm trying to implement it into my program but i'm having trouble.
Keep in mind I'm new to MFC.
It says: "Add a member of type CFontPreviewCombo to your dialog and attach it to your control."
How do I do this? I'm not sure what the member part means. Thanks for any help.

hello experts,
I created a TimerThread class that derive from CWinThread,
class TimerThread: public CWinThread
{
public:
TimerThread();
SYSTEMTIME* start_time;
SYSTEMTIME* end_time;
VOID SetStartTime(SYSTEMTIME*);
VOID CopyTime(SYSTEMTIME*, SYSTEMTIME*);
};
and I have a global TimeThread* timerThread;
timerThread=AfxBeginThread(RUNTIME_CLASS(TimerThread));
I got the following error, i don't really understand it...
thanks for the help.
C:\sampleC++\dlg\dlgDlg.cpp(130) : error C2039: 'classTimerThread' : is not a member of 'TimerThread'
c:\samplec++\dlg\timerthread.h(2) : see declaration of 'TimerThread'
C:\sampleC++\dlg\dlgDlg.cpp(130) : error C2065: 'classTimerThread' : undeclared identifier

In your code "classTimerThread" is one world. What is it and where is it declared?

sorry the error was thrown at this line:
timerThread=AfxBeginThread(RUNTIME_CLASS(TimerThread));
so it seems RUNTIME_CLASS() returned a classTimerThread or something.. I don't understand..
thanks for the help

From the MSDN: You must derive your class fromCObject and use the DECLARE_DYNAMIC and IMPLEMENT_DYNAMIC, the DECLARE_DYNCREATE and IMPLEMENT_DYNCREATE, or the DECLARE_SERIAL and IMPLEMENT_SERIAL macros.

I was looking at a tutorial here on codeproject and wasn't to sure about how to include the control into my own project. I figured if I post here instead of on the page for the project I may get more responses or someone who has done it. here is the URL
http://www.codeproject.com/richedit/AutocomplectionCtrl.asp
I wanted to put it in a SDI app. Should I just inherit the CRichEditView class? I'm kind of confused on how to incorporate it. Any examples or help would be greatly appreciated! Thank you

hi guys, I used appWizard to created a dialog that has a dropdown combobox on it, it's id is DROPDOWNHRSFN, my question is that, inside of its event handler code, how would I be able to obtain a reference of the dropdown combobox? I would like to get the item that the user selects from the combobox. how would I do that? And How would I initialize this combobox with my custom data?
thank you so much
void CDlgDlg::OnDropdownHrsfn()
{
MessageBox("drop down","drop down",MB_OK);
// TODO: Add your control notification handler code here
}

As the sig says, Im new to this entire game! Im not only learning VC++, but the IDE to boot! Gosh.. Gimme some Tylenol!! 
Ive got a string variable, Number1, I want to convert it Long, but the linker give the message:
error C2664: 'strtol' : cannot convert parameter 1 from 'class CString' to 'const char *'
Heres the code snippit:
===========================================================
GetDlgItemText(IDC_EDIT1, Number1);
GetDlgItemText(IDC_EDIT2, Number2);
CString TmpTxt = "The numbers are " + Number1 + " and " + Number2;
MessageBox( TmpTxt, _T("Error"), MB_ICONINFORMATION | MB_OK);
// Everything above works fine, below is conversion
// which wont work.
long Ans;
Ans = strtol(Number1, NULL, 10);
===========================================================
This is a stupid newbie project, enter two numbers in two Edit Boxes, convert the text var to a long var, add the two, convert it back to text and give a message box with the sum of the two.
I have the Member Variable assigned to IDC_EDIT1 as CString using Number1, and 2 respectively.
I am using eVC++ 3.0 for WinCE.
Any help, thanks much in advance!
This *aint* VB, dats fur sure!
PS
Please reply as if I were a total idiot, becaue I am!

The raw CString is not a character string (as you can see.)
PocketBlast wrote:
long Ans;
Ans = strtol(Number1, NULL, 10);
Try
Ans = strtol((LPCSTR)Number1, NULL, 10);
This gives you a pointer to the character data.

You're using the wrong function. strtol() is only for ANSI strings. Since WinCE is a Unicode OS, use wcstol() instead, which is the Unicode version.
