Help with NetMessageBufferSend()

I'm trying to write a 'net send' spoofer and I need some help with the NetMessageBufferSend() function. I read about it at Microsoft's website, but they don't go into much detail about it and it's internal workings (and all of it's parameters). I have a few questions:

1) I'm assuming this function is part of the Window's API (which I don't really know much when it comes to using it). Is it possible to use this function but still use the regular MS-DOS window? I want it to be a simple program that uses regular input and output (cin/cout).

2)What header file(s) contain(s) everything I need to use this function?

Much thanks to anyone who can help out.

2) The msdn says you need to include Lm.h, and link Netapi32.lib

Yes you can use any of the features of the Win32 API from within a console program, a console program is a window after all. Just a special when that you as the programmer are removed from the responsibility of handling directly if you do not want to.

Hell you can even multitask in a console program if you want to.

How do I do that?

what compiler?

Alright, I have the thing down to just 2 errors, but I don't know what to do.

Line 33 C:\Documents and Settings\Owner\My Documents\John's Documents\Source Files C++\Spammer.cpp cannot convert `const char*' to `const WCHAR*' for argument `2' to `DWORD

Line 34 C:\Documents and Settings\Owner\My Documents\John's Documents\Source Files C++\Spammer.cpp cannot convert `char*' to `const WCHAR*' for argument `2' to `DWORD

Here's the code:

Code:

---

#include <iostream>
#include <cstring>
#include <windows.h>
#include <Lm.h>

using namespace std;

int main()
{
   
    char fromName[20];
    char computerName[20];
    //char netSend[]="net send ";
    char message[100];
    char fake[30];
    char completeCommand[140];
    int num;
   
    cout<<"Welcome, you are about to have the best fun of"
        <<"\nyour typing career at the expense of someone else!"<<endl;
   
    cout<<"Please enter the name of the computer you want to spam: ";
    cin.getline(computerName, 20);
    char* compConst = computerName;
    cout<<"Please enter the message you wish to spam with (must be below 100 chars): ";
    cin.getline(message, 100);
    int length = strlen(message);
    cout<<"Please enter the assumed name: ";
    cin.getline(fake, 30);
    char* nameConst = fake;
    cout<<"Please enter the number of messages you wish to send to that alias: ";
    cin>>num;
    NetMessageNameAdd(NULL,"RECTOR");
    NetMessageBufferSend(NULL,compConst, fake, message, length);
   
    cout<<"Done."<<endl;
    system("PAUSE");
    return 0;
}

What is going on here? The bolded is where the errors are occuring.

You are using windows functions here and thus must use windows datatypes. Here are the function defs:

Code:

---

NET_API_STATUS NetMessageNameAdd(
  LPCWSTR servername, 
  LPCWSTR msgname     
);

---

and

Code:

---

NET_API_STATUS NetMessageBufferSend(
  LPCWSTR servername, 
  LPCWSTR msgname,   
  LPCWSTR fromname,   
  LPBYTE buf,         
  DWORD buflen       
);

---

Note the functions are expecting to be passed LPCWSTR not char*. So either change your datatypes to WCHAR for your arrays and LPCWSTR for your pointers or do an explicit typecast.

edit:
LPCWSTR = Long Pointer Wide Character String.

edit2:
These are all windows datatypes. They are essentially just macros. You can find there meanings on MSDN.

I'm still not sure if it works right because I don't actually have a lan at my house. We like to use this crap at school. Is it possible for anyone to test this for me? Here's the code once again:

Code:

---

#include <iostream>
#include <cstring>
#include <windows.h>
#include <Lm.h>

using namespace std;

int main()
{
   
    char fromName[20];
    char computerName[20];
    char message[100];
    char fake[30];
    char completeCommand[140];
    int num;
   
    cout<<"Welcome, you are about to have the best fun of"
        <<"\nyour typing career at the expense of someone else!"<<endl;
   
    cout<<"Please enter the name of the computer you want to spam: ";
    cin.getline(computerName, 20);
    char* compConst = computerName;
   
    cout<<"Please enter the message you wish to spam with (must be below 100 chars): ";
    cin.getline(message, 100);
   
   
    cout<<"Please enter the assumed name: ";
    cin.getline(fake, 30);
    char* nameConst = fake;
   
    cout<<"Please enter the number of messages you wish to send to that alias: ";
    cin>>num;
   
    int msg = strlen(message);
    NetMessageNameAdd(NULL,LPCWSTR("RECTOR"));
    for(int i = 0; i<num; i++){
    NetMessageBufferSend(NULL,(LPCWSTR)compConst, (LPCWSTR)nameConst, (BYTE*)message, msg*2);}
   
    cout<<"Done."<<endl;
    system("PAUSE");
    return 0;
}

What type is the return value of the NetMessageBufferSend() function? I know the microsoft thing actually lists the return values, but what are the types of those values?

Quote:

Return Values
If the function succeeds, the return value is NERR_Success.

If the function fails, the return value can be one of the following error codes.

Return code Description
ERROR_ACCESS_DENIED The user does not have access to the requested information.

ERROR_INVALID_PARAMETER The specified parameter is invalid.

ERROR_NOT_SUPPORTED This network request is not supported.

NERR_NameNotFound The user name could not be found.

NERR_NetworkError A general failure occurred in the network hardware.
