What do you mean with getting the format? If it's a binary file and you don't know how to interpret its contents, I don't think you can get a format.
Regarding the reversion, thats quite easy, although I don't see the point in doing it. You could use the functions fread(), frwite() and the like to read it into a large enough char array, loop through it from back to front and write it byte by byte into a new file (assuming is is small enough to fit into memory).

There is a free game development tool called "Wolf RPG Editor". Details on the following site,
http://www.silversecond.com/WolfRPGEditor/[^]
The problem is that its been written in Japanese. Using Resource Hacker[^] I managed to translate one of the configuration tools that came with it. For reference here are screenshots of my efforts,
BEFORE,
http://img507.imageshack.us/img507/4545/configjapanese.jpg[^]
AFTER,
http://img811.imageshack.us/img811/3365/configenglish.jpg[^]
My next plan is to try and work with a few friends to translate the rest of the tool. Basically, it revolves around changing the text in the dialog boxes. The problem I'm facing is how to manage such a team effort.
Does anyone know a way (or utility) to extract the resources from a windows executable, split it into different files and then merge it all back together?
As useful as Resource Hacker is, its essentially a one-man tool. I'm looking for something that would let me work with a version control system for this.
On the legal side of things, I've been led to understand that the original developer has granted permission for translation efforts (admittedly, hearsay from others). The way I see things, since its a free tool and because I'm only translating it, there shouldn't be any trouble.

There's a bunch of commercially availble tools for the job, you could check out Deja Vu, SDL Passolo or Idiom. If you google around for Flexytrans, you may find that one (it should be for free if you manage to find it).
The more elaborate tools have loads of functions for working in teams. For the simpler ones, use the Clipboard to export the strings to text files.

Compile same code twice, why the result(exe) is not same。both release mode and debug mode exist the same problem。if want to get same result, how to setting to the project, such as compile option。
|
|
|
|
|
What did you do, exactly, to get to this observation? Usually, when you build a project, you overwrite the previous build, so there's nothing to compare it to.
|
|
|
|
|
The differences are probably superficial. For example, an exe or dll contains a date-time stamp which specifies the time it was linked.

Can you explain little more please. What do you mean that result is not same? output?you just clear all in build option and rebuild the solution again.
|

I suppose you are compiling with VS. What differs is a timestamp added by compiler (more precisely, by linker). I don't remember where, but I think is somewhere in IAT. You can patch those bytes (I think is a __int64, most likely a FILETIME) either by patching the binary or by setting system time (not sure since you don't know when exactly the linking occurs).

Please don't repost the same question. You have already asked this in the Q&A section.

Is it possible in C++ to declare a pointer as long?( like long int).
I'm reading some string from a XML file and assigning it to a <code>const char*</code> variable.
But the application crashes, when string is huge. Is there any maximum limit for char * variable?
How to avoid the crash,when the string is huge?

On most platforms, both are 32-bit so there would be no difference.

A pointer just points to something.

Showing the relevant code, for starters.

A pointer is a pointer is a pointer; it is a fixed size and has nothing to do with the length of the item(s) that it is pointing to. You need to use your debugger to investigate why your program is crashing.
One of these days I'm going to think of a really clever signature.

That doesn't make sense. A pointer can only be sensibly initialized within the program, at runtime, because only then does the computer know where in memeory every object lies. Therefore it doesn't make sense to either store or restore a pointer to/from a file!
What you need to do instead is:
1. read that string from your file
2. Allocate a char array on the heap that is big enough to contain that string (including the terminating NULL character!)
3. Assign that array to your pointer
4. Store the string in that char array.
Of course, if you use std::string, that would save you some of that efort.

I think the "it" the OP was referring to was the string, not the file.

I'm not so sure - he (or she) asked about using a bigger pointer type after all.
In any case, I've found that it's often better to take a question literally - if it isn't meant that way, it helps the author to improve on it and provide a better description of the actual problem.

Application crash has nothing to do with the size of the pointer. You should show us the relevant code to get better help.

A pointer is just a pointer, just pointing to something. I think your application is crashing with some other reason. just debug the code and ensure what is the problem.. if you are using visual c++ just using LPCTSTR variable for storing string data read from xml.

Hello there,
In computer science, a pointer is a programming language data type whose value is directly linked to another - by means of pointing to the value that is stored elsewhere in the computer memory using its address.
The basic syntax is define a pointer is as follows:
int *ptr
Now, because a pointer points to a memory location - I don't believe that it can be define as long.

i need to make program that i give some system command like ls,date et cetera.and to check if thre is path that include this command(file).i have variable commandandparameters that start to change in the last loop while and i dont know why.
i put puts(commandandparameters); to show that the output is not good if you want to run it.
#include <stdio.h><br />
#include <string.h><br />
#include <stdlib.h><br />
void main()<br />
{<br />
char *arr[5];
char command[10];<br />
int i,j;<br />
char *path=NULL,*tempath,*finalpath,*commandandparameters;<br />
do<br />
{<br />
i=0;<br />
printf("enter new command:");<br />
gets(command);<br />
arr[i]=strtok(command," ");<br />
while(arr[i]!=NULL)
{<br />
i++;<br />
arr[i]=strtok(NULL," ");<br />
}<br />
strcpy(commandandparameters,arr[0]);
for(j=1;j<i;j++)
{<br />
strcat(commandandparameters," ");<br />
strcat(commandandparameters,arr[j]);<br />
}<br />
path = getenv("PATH");<br />
tempath = strtok(path,":");<br />
while (tempath != NULL)<br />
{<br />
strcpy(finalpath,tempath);
puts(commandandparameters);<br />
strcat(finalpath,"/");
execl(finalpath,commandandparameters,NULL);<br />
tempath = strtok(NULL, ":");
}<br />
}while(command!="leave");<br />
}

Some code is missing in your post.
(And please, elaborate a bit).
Veni, vidi, vici.

Your question is not clear, and your code snippet is incomplete. However I did notice the line:
strcpy(commandandparameters,arr[0]);
This is likely to fail since you have not initialised commandandparameters to point to anything.
Note, please use <pre> tags around your code (as I have done above), rather than <code> tags.
One of these days I'm going to think of a really clever signature.
