Source browser command line? Utility?

Visual C++ 6 or Embedded Visual C++ support the notion of a source browser, should it be enabled. It's quite useful and allows rapid navigation across the project for a variety of things. Does anyone know if there is a command line interface for it?

I would like to be able to ask the browser (or any other tool for that matter): please list for me all of my classes and their member functions. Please sort by class name, public then private methods.

Any one have any suggestions? I could do this years ago on a mini. True, I didn't have visual editting, but the command line / text output was valuable for custom processing....

Bonjours
I wish to add a add in in exel XP 2002 with Windows SP2.

For that I have three file has to install:

1 fichier.lgc has to install in \ Windows \ applog
First problem I do not find this repertory hidden under same XP SP2 with the good options to select in Windows to explore. Thus I have to arrange this file in \ Windows \ appPatch and in \ Windows \ Prefetch in the place and the problem comes from I think.

1 fichier.xll has to install in \ office \ xlstart
1 fichier.ppp has instaler in \ office \ xlstart

And when the double click on the fichier.xll for the throw the error message is as follows “WinRT Driver not installed”.

Thus my questions are is this normal that I do not find the file \ Windows \ applog under win XP SP2 and how to install WinRT driver. Or then where to arrange my fichier.xll which must normally be in the repertory \ Windows \ applog

Thank you has all in advance for your assistance.

<br />
              for(hi_index = low_index+1;p_array[hi_index] != 0;hi_index++){ // I wonder why <br />

                      comp_val=strcmp(p_array[hi_index],p_array[low_index]);<br />

It's the loop control variable.

Here's the deal. I am developing an internet multiplayer game. The game has many regional variations, rules and scoring systems. Rather than hardcode all this information into the program, I have built in a script parser, so now all users need to do is write a scripted extension to the game. The script will then parse data from the exe checking the validity of a game and/or returning a score.

The thing I'm worried about is users hacking these scripts for their own benefit. I could create and embed a hash key into the script and send this across the network, but even that could be modified. Any thoughts on this?

This is not reliable. For example what about windowess controls. Also even if the control has a HWND is may not be a child of the dialog - when ATL hosting code is used this be the case for example.

First you have to decide what kind of rounding you’re after. There are four common ways rounding can be performed:
- Towards +ve infinity.
- Towards -ve infinity.
- Towards 0.
- Away from 0.

Towards +ve infinity:
In this mode we choose the closest number that’s higher. For example, if rounding to the nearest integer:
1.6 -> 2
-1.6 -> -1

Towards -ve infinity:
In this mode we choose the closest number that’s lower. For example, if rounding to the nearest integer:
1.6 -> 1
-1.6 -> -2

Towards 0:
In this mode we chose the closet number in the direction of zero. For example, if rounding to the nearest integer:
1.6 -> 1
-1.6 -> -1

Towards 0:
In this mode we chose the closet number in the direction away from zero. For example, if rounding to the nearest integer:
1.6 -> 2
-1.6 -> -2

For simplicity I’ll only consider the “Towards +ve infinity” mode. If you want to round a double or float to the closest integer code like this will do it:
int n = double_val+0.5;

To a double to the nearest tenth:
double n = floor(double_val*10.0+0.5)/10.0;

To a double to the nearest hundredth:
double n = floor(double_val*100.0+0.5)/100.0;

First, thank you all for your answers, they are proving very helpful.

Now, however, I've encountered a different issue:

I get the right results from the floor function. However, when I do the final division (I'm getting this information from stepping through the code in the VC++ .NET Debugger):

//m_fAmount is a float
m_fAmount = 30679.000
iDivisor = 1000.0000

m_fAmount / iDivisor yields: 30.679001

I am really puzzled as I'd like to think that the compiler can do simple arithmatic Smile | :)

However, in all seriousness, what's causing this, I'm really puzzled.

Any and all help is greatly appreicated.

Thanks,
BP
