Display Strings

I have an EXE file and i want to list all the strings from the String Table of the EXE
The exe is the compiled CPP file like the one present in the Debug folder
How do i display all the strings that are present??

Try this article.

Cheers

I already answered you in your previous thread. What was wrong there for you? :confused:

I have used this code till now. Is this proper?

#include "stdafx.h"
#include "windows.h"
#include "tchar.h"
#include "stdio.h"
#include "string.h"

BOOL CALLBACK MyStringCB(HMODULE some_library,LPCTSTR RT_String,LPTSTR buffer,LONG_PTR aux_param);

char buffer[200];

int _tmain(int argc, _TCHAR* argv[])
{DWORD S;
LPCTSTR RT_String=NULL;
LONG_PTR aux_param=NULL;
BOOL q,r;
HMODULE some_library = LoadLibrary("C:/Hi/Debug/Hi.exe");
q= MyStringCB(some_library,RT_String,buffer,aux_param);
r=EnumResourceNames(some_library, RT_STRING, MyStringCB, aux_param);

S=GetLastError();

return 0;

}

BOOL CALLBACK MyStringCB(HMODULE some_library,LPCTSTR RT_String,LPTSTR buffer,LONG_PTR aux_param)
{ DWORD startId = ((DWORD)buffer - 1) * 16;
DWORD i, endId = startId + 16;
for (i = startId ; i < endId; ++i)
{ LoadString(some_library, i,buffer,sizeof(buffer));
}
return TRUE;
}

No. Some serious problem are there.
1. Always use Code tags while posting code snippets. Otherwise your code is almost unreadable.
2. Don't be so lazy to *no* insert spaces after commas - the same reason as above.
3. Why are you using obsolete char type instead of TCHAR?
4. What does this magic number '200' mean? Why not '20' or 2000'?

Code:

LPCTSTR RT_String=NULL;

Wrong! You may not redefine this value. Otherwise the rest of your code does not make any sense!

Code:

HMODULE some_library = LoadLibrary("C:/Hi/Debug/Hi.exe");

Wrong! you must use double backslashes!

Code:

r=EnumResourceNames(some_library, RT_STRING, MyStringCB, aux_param);

S=GetLastError();

Wrong. GetLastError makes any sense only if API call failed. So:

Code:

---

if(!EnumResourceNames(some_library, RT_STRING, MyStringCB, aux_param))
    S=GetLastError();

Wrong! MyStringCB is a callback function and is called by the system from within the EnumResourceNames (or some other) API. You must not call it yourself!

Well, did you read the article i referred to? :confused:
Did you try to download the Microfoft code to get/read/update string resources? :confused:

We made the changes suggested by you. While debugging the error is that RT_String needs to be initialized.
Yes i downloaded the STablUpd and am very new to C++ ,just started 2 months back.


#include "stdafx.h"
#include "windows.h"
#include "tchar.h"
#include "stdio.h"
#include "string.h"

BOOL CALLBACK MyStringCB(HMODULE some_library,LPCTSTR RT_String,LPTSTR buffer,LONG_PTR aux_param);

char buffer[200];

int _tmain(int argc, _TCHAR* argv[])
{DWORD S;
LPCTSTR RT_String;
LONG_PTR aux_param=NULL;
BOOL q,r;
HMODULE some_library = LoadLibrary("C:\\Hi\\Debug\\Hi.exe");

//q= MyStringCB(some_library,RT_String,buffer,aux_param);
r=EnumResourceNames(some_library, RT_STRING, MyStringCB, aux_param); //ERROR HERE.
//MyStringCb is not being called

if(!EnumResourceNames(some_library, RT_STRING, MyStringCB, aux_param))
S=GetLastError();

return 0;

}

BOOL CALLBACK MyStringCB(HMODULE some_library,LPCTSTR RT_String,LPTSTR buffer,LONG_PTR aux_param)
{ DWORD startId = ((DWORD)buffer - 1) * 16;
DWORD i, endId = startId + 16;
for (i = startId ; i < endId; ++i)
{ LoadString(some_library,i,buffer,sizeof(buffer));

}

return TRUE;
}

The line:

Code:

---

LPCTSTR RT_String;

---

is just a declaration of a pointer. You need to create a memory area to hold actual string.

You should write:

Code:

---

LPCTSTR RT_String = new TCHAR[desired size];

---

Don't forget to call the delete operator when you no longer need the string.
