get username as string (windows c++)

[lumpybanana247]

how could i get the username as a string? this gets it as "char", but i need it as a string.

#include <iostream>
#include <windows.h>
using namespace std;
int main()
{
    char acUserName[100];
    DWORD nUserName = sizeof(acUserName);
    if (GetUserName(acUserName, &nUserName)) {
        cout << "User name is " << acUserName << "." << endl;
        cin.get();
    }
    return 0;
}

A char array is the same as a string except it has a '\0' terminator. If you want to construct a char array to a string, try this:

string userName(acUserName);
 

Why would you want it as a string?

Maybe like this:

#include <iostream>
#include <windows.h>
using namespace std;
#include <string>
int main()
{
    char acUserName[100];
    string UserName;
    DWORD nUserName = sizeof(acUserName);
    if (GetUserName(acUserName, &nUserName)) {
        UserName = acUserName;
        cout << "User name is " << UserName << "." << endl;
        cin.get();
    }
    return 0;
}

i changed my code a little bit and i now got the problem

cannot convert 'std::basic_string<char, std::char_traits<char>, std::allocator<char> >' to 'char*' for argument '1' to 'bool EmptyDirectory(char*)'

ON_COMMAND_BY           (delhistory){
    char acUserName[100];
       string UserName;
       DWORD nUserName = sizeof(acUserName);
       if (GetUserName(acUserName, &nUserName))
       UserName = acUserName;     
       list.add("History");if( EmptyDirectory( "C:\\Documents and Settings\\"+UserName+"\\Local Settings\\History\\History.IE5\\" ) != 0 ){delhistory.disable();}else{}}
 

[i want it as a string so i can add it as part of '"C:\\Docu...."+UserName+"...."

thanks,

That means that the EmptyDirectory() function takes a pointer to a character or a char array. Maybe you don't want a string after all.
You can try two things:
Make everything char arrays and use strcpy():

char path[200];
strcpy(path, "C:\\Documents and Settings\\");
strcat(path, acUserName);
strcat(path, "\\Local Settings etc....");
if (EmptyDirectory(path) != 0){
//do stuff
}
 

or you can add .c_str() at the end of the whole path:

if( EmptyDirectory( "C:\\Documents and Settings\\"+UserName+"\\Local Settings\\History\\History.IE5\\".c_str()) != 0 )
//do stuff
 

Try it and see what happens.

IGNORE!!

i tried

  ON_COMMAND_BY           (delhistory)  {list.add("History");
  char acUserName[100];
       string UserName;
       DWORD nUserName = sizeof(acUserName);
       if (GetUserName(acUserName, &nUserName))
       UserName = acUserName;     
                                        if( EmptyDirectory( "C:\\Documents and Settings\\"+UserName+"\\Local Settings\\History\\History.IE5\\".c_str() ) != 0 )
                                        {delhistory.disable();}else{}}
 

and i got the error:
request for member 'c_str' in '"\\Local Settings\\History\\History.IE5\\"', which is of non-class type 'const char [37]'


ill try the str copy way and post another message

whoopee!!

  ON_COMMAND_BY           (delhistory)  {list.add("History");
  char acUserName[100];
       string UserName;
       DWORD nUserName = sizeof(acUserName);
       if (GetUserName(acUserName, &nUserName))
       UserName = acUserName;     
 
char path[200];
strcpy(path, "C:\\Documents and Settings\\");
strcat(path, acUserName);
strcat(path, "\\Local Settings\\History\\");
if (EmptyDirectory(path) != 0){
 
                                        delhistory.disable();}else{}}
 

worked!

thank you very much
