Are you saying you want to store it like this:
; Valid values are ONESTOPBIT, ONE_5STOPBIT, TWOSTOPBIT
StopBits=ONESTOPBIT
or like this:
; Value values are 1, 1.5, 2
StopBits=1
In the first case, just use string comparisons. In the second, you have a couple options as well: Read them in as floats and use conditionals to set them to the proper setting (a bit risky since precision can be an issue), or force the values to be multiples of 10x so the file would look like this instead:
; Value values are 10, 15, 20
StopBits=10
Then simply use a switch statement to convert those integers to the proper defined values for stop bits.
Your best bet for making it easily readable is still to use XML and create a schema to validate it against so that you can let the parser determine if you have valid values before you even look at the data.

What I mean is:
For now I use:
//////////////////////////////
DCB dcb;
dcb.BaudRate = inifile.getInt("Baudrate"); //Accepts int
dcb.StopBits = inifile.getInt("StopBits");//Accepts int
//////////////////////////////
and so on...
inifile is my created class where getInt(char* paramname) is returning value of type 'int', which is acceptable to DCB class. As you know originaly it would be done like this:
/////////////////////////////
dcb.BaudRate = CBR_9600; //Accepts DWORD
dcb.StopBits = ONESTOPBIT; //Accepts DWORD
/////////////////////////////
where CBR_9600 and ONESTOPBIT are defined by c++ like 9600 and 0.
What I want to do is store those settings in config file (doesn`t matter ini or xml) as strings CBR_9600 and ONESTOPBIT and then read them.
This won`t work:
//////////////////////////////
dcb.BaudRate = inifile.getTxtVal("BaudRate");
//////////////////////////////
because getTxtVal() returns char[] (wich is not acceptable for DCB) variable containing CBR_9600.
May be it is now easyer to understand what i was trying to say.... 
But maybe I`m a lOl.

You can store them as strings, but you will have to do a string comparison in your code to convert them. ONESTOPBIT, CBR_9600, etc are usually either #define's or enums (can't remember off the top of my head, but it doesn't matter). If you get a string "ONESTOPBIT" in, you can't convert that to ONESTOPBIT (the constant) by just casting it; you have to tell it what you want it to be:
string sBaud = inifile.getTxtVal("BaudRate");
unsigned long baud = CBR_38400;
if (sBaud == "CBR_9600")
{
baud = CBR_9600;
}
else if (sBaud == 14400)
{
baud = CBR_14400;
}
...
dcb.BaudRate = baud;

Thanx that was exactly what I wanted to know .
It`s a pity that there`s no way to use the returned string directly..
O.K. ill start to write the missing piece of code for my inifile class..
Thanks again!

You have to keep in mind that enums and defines are NOT strings. enum's are basically constant integers and defines are preprocessor directives that get changed out before compiling.

So why can't you? Use sprintf(), or equivalent, to format the string and then write that string to the .ini file. Are you looking for atoi(), perhaps?
Otherwise, I'm just not following what you are after. Perhaps you could show what you want the .ini file to look like.

I was doing a lot of cut and paste on several dialogs, but then I look at the resource.h file, some defines have the same value.
Are they any programs to check this file and correct the problems.
See sample below:-
#define IDC_POWER_LABEL 1742<br />
#define IDC_MAIN_RX_SQUELCH_LABEL 1743<br />
#define IDC_MODULATION_LABEL 1744<br />
#define IDC_COMBO1 1745<br />
#define IDC_COMBO_MODULATION 1746<br />
#define IDC_START_IBIT_LABEL 1746<br />
#define IDC_GUARD_RX_LABEL 1747<br />
#define IDC_TEST_TYPE_LABEL 1747<br />
#define IDC_GUARD_RX_BUTTON 1748<br />
#define IDC_IBIT_STATUS 1748<br />
#define IDC_GUARD_FREQ_LABEL 1749<br />
#define IDC_TEST_TYPE_STATUS 1749<br />
#define IDC_COMBO_GUARD_FREQ 1750<br />
#define IDC_WARNINGS_LABEL 1750<br />
#define IDC_MARITINE_SHIP_SHORE_LABEL 1751<br />
#define IDC_WARNINGS_STATUS 1751<br />
#define IDC_SHIP_SHORE_BUTTON 1752<br />
#define IDC_ERRORS_EXIST_LABEL 1752<br />
#define IDC_MARITIME_INT_USA_LABEL 1753<br />
#define IDC_ERRORS_EXIST_STATUS 1753<br />
#define IDC_INT_USA_BUTTON 1754<br />
#define IDC_SRUS_ERRORS_LABEL 1754
Help!

I had one problem with same IDs like your code so my suggestion use of different values.

No kidding! He already wants unique numbers. His question was about a program to do that for him.

I think ResOrg ( found here on CP ) can do that.

Has this program been updated for VS 2005.
I had problems with it om VS 2003, does most of the things wright but gets IDD for the Aboutbox and Menu wrong.

That's correct, you may have exactly the same control IDs in different dialog boxes.
The simplest example is: IDOK, IDCANCEL.

Unless you want to map the control ID to a help file context using MakeHm or something similar, in which case you want ALL controls to have unique ID within the application - at least all of them that will have context-sensitive help.
Maybe that is why he wants them all to be different.
Any sufficiently gross incompetence is nearly indistinguishable from malice.

Hello Everyone.
I have the following C code snippet:
long TAPEINFO(nparm, parmptr, parmdec)
WORD nparm;
BYTE **parmptr;
FINFO *parmdec;
{
....Code in the function goes here....
}
I'm not an expert by any means in C but I have done a litte C development on Linux and have never seen code like this before. The variables that are defined directly below the function header seem wierd.
The problem is a compile error stating "nparm is undefined" and pointing at nparm in the function header line.
Is the definition after the function header supossed to define nparm?
If someone could provide any feedback I'd appreciate it.
Thanks.

It is an old Kernighan and Ritchie (K & R) style function equivalent to
long TAPEINFO(WORD nparm, BYTE **parmptr, FINFO *parmdec)
{
.........
}

Do you think the compile error could be because the compiler doesn't recognize the syntax? Here is the compiler output:
"usrfunct.c", line 91: error #2020: identifier "nparm" is undefined
long TAPEINFO(nparm, parmptr, parmdec)
^
"usrfunct.c", line 91: error #2020: identifier "parmptr" is undefined
long TAPEINFO(nparm, parmptr, parmdec)
^
"usrfunct.c", line 91: error #2020: identifier "parmdec" is undefined
long TAPEINFO(nparm, parmptr, parmdec)
^
"usrfunct.c", line 92: error #2130: expected a "{"
WORD nparm;
I've actually been emailed the source and just asked to see if I can figure out why it won't compile. I think it is an HP UNIX box. By looking at the make log it seems like the compiler is called aCC. Once again never seen this but have never worked with C on HP UNIX before.
Thanks for your help.

What compiler and version are you using?
CC is usually an environment variable pointing to whatever C-compiler you want to use. Typically, you will see the makefile (or configure script) have something along the lines of:
CC=gcc
...
$(CC) $(CFLAGS) usrfunct.c
Depending on what compiler you are using, you may have to set a flag to allow it to read old-style syntax (K&R C).

Sounds like a strong possibility which is easily checked.
Three options:
1. Just convert the function over from K&R style parm list to an ANSI style list and give it a try.
2. Do a man on aCC and try and figure out what compiler flag enables K&R.
3. You should be able to do something like is done is this example because I believe all ANSI compilers predefine __STDDC__:
#ifdef __STDC__
void psm_update_cfg_srcs(UINT16 srcs, UINT16 installed, UINT16 present,
UINT16 enabled)
#else
void psm_update_cfg_srcs(srcs, installed, present, enabled)
UINT16 srcs;
UINT16 installed;
UINT16 present;
UINT16 enabled;
#endif

It's the orginial C syntax before the ANSI C standards. The first edition of The C Programming Language was written in this style. You should be able to get a used copy on Amazon.com. People usually refer it as K&R C.

Hi,
You can set Home Page (formerly Start page) by modifying following registry entry:
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\Start Page
There's also Micro$oft's default value called First Home Page.
