After so many questions regarding strings, parsing and related stuff, don't you think it's about time to read some actual books or articles to learn all this? Or do you intend to keep asking for the rest of your life?
Seriously, the time you keep spending on low level programming questions like this would have been better spent by reading up and learning something by yourself. You are doing yourself and everyone else a disservice by asking questions without ever even trying to look something up and really understand the things you are dealing with.
Regarding this particular question, simply reading up on strtok would solve it, easily.

Have you tried something like:
char *pszSource = "login#user#1 username password";
char *pszPos = strstr(pszSource, "user#1");
int nLen = pszSource - pszPos;

I get these compile errors "warning C4129: 'N' character escape sequence.
I think I just did something dumb, because I have other lines that are fine in the same code block. I'm not really sure what to make of it.
L" /SAPWD=\"securePassword1\";"
but this line errors on \"N
L" /AGTSVCACCOUNT=\"NT_AUTHORITY\NETWORK SERVICE\""

You have to escape the backslashes in the middle of the string, like this:
L" /AGTSVCACCOUNT=\"NT_AUTHORITY\\NETWORK SERVICE\""

I get it now, I escaped out the doublequote, but I didn't bother to look in the center. I was too busy looking at the doublequote.
It was a dumb mistake, Thanks for your help.

Dear All,
The code below is C Programming that i wrote and is working but I am having problem in reading any records I am saving into text File called "MY FILE".Also anytime to ADD NEW RECORD in my switch case selection,the initial record that was in the is been deleted automatically.Did any one know what is wrong.I can figure it out,i have been tried debugging but all to no avail.I will appreciate your ideas.Thanks

Please wrap your code using <pre> and </pre> tags... this is painful to look at.

That appears to be contradictory. It's either working or it isn't.

Hard to tell since you've not shown any code that reads or writes. The only thing you've shown is menu code which is completely irrelevant to the problem.
Use the debugger to narrow the problem down to just a handful of lines, then come back and post those.

First off, I'm not sure if I'm quite in the right forum or not, so just let me know if I should post elsehwere. With that said...
I'm brand new to C++ and am trying to wrap my brain around something. I know that I can use a MAIN function in a .CPP file and use it to grab command line arguments. I'm trying to add this feature to an existing clump of code we've got at work (I'm trying to expand my skills, and it's a small utility we techies use only occasionally). Anyway, I can't figure out how to use a MAIN function if there isn't already one (I can make it work in a brand new test project just fine). My current attempt to tweak the code sort of looks like this:
#include "stdafx.h"
#include ...a few other files.....
class CApp : public CWinAppEx
{
public:
CApp();
public:
virtual BOOL InitInstance();
};
extern CApp theApp;
int main(int argc, char *argv[])
{
MessageBox(NULL, L"This should display first, but doesn't currently show up at all.", NULL, NULL);
}
CApp::CApp()
{
MessageBox(NULL, L"This should display second, but currently shows up first.", NULL, NULL);
}
CApp theApp;
BOOL CApp::InitInstance()
{
MessageBox(NULL, L"This should display third, but currently shows up second.", NULL, NULL);
...does other stuff here...
}
So what do I need to do to use MAIN correctly to grab the command line arguments?
Thanks!

You have code for a Windows application there. And it also looks like it is using MFC. You won't find a main(), nor will you need to. Odd, though is that you have 'theApp' declared twice. That's definitely not a good start.
There are methods of the CWinAppEx class that can be called in InitInstance to assist with command line handling.

As others have said, you either have main() or you have your WinApp (theApp) but not both. And definitely not two instantiations of theApp.
The command line arguments can be accessed during your InitInstance() function by looking at the m_lpCmdLine data member of your class.
There are a number of classes / functions that can help you parse it in the argc/argv style you're accustomed to, links are in earlier answers to this question.

in your CWinApp:InitInstance, you should be able to access the __argv and __argc variables.

I did not know that, been tokenizing m_lpCmdLine myself. +5 for the info.

Hi ,
How can we represent structure bitfiled in the UML Model??
|
|
|
|
|
|
If i have the following case,
Struct Mode
{
union
{
unsigned char MSB;
struct
{
unsigned char a:2
unsigned char b:3
unsigned char c:3
}
}
}
How to model the struct "Mode" in the class diagram?
|
|
|
|
|
[ Here ] is a good UML primer.
#include <iostream>
using namespace std;
class c_Mode
{
public:
union
{
unsigned char MSB;
struct
{
unsigned char a:2;
unsigned char b:3;
unsigned char c:3;
};
};
} ;
struct s_Mode
{
public:
union
{
unsigned char MSB;
struct
{
unsigned char a:2;
unsigned char b:3;
unsigned char c:3;
};
};
} ;
int main()
{
c_Mode clsMode;
clsMode.a=0;
clsMode.MSB=0;
s_Mode mode ;
mode.a=0;
mode.MSB=0;
return 0;
}

People Hi!People, prompt why VC ++ doesn't open title files, can where it is necessary to adjust?
It is all to be in one folder, and doesn't want to open.

Your question is not very clear, but if you are having trouble accessing files in your project then check that the location property is correct.
