save to temp dir?

Ok i want to save to the temp directory this is wat i have so far

Code:

---

#include <iostream>
#include <fstream>
#include <string>

using namespace std;

int main(){

int test (123);
string line;

                ifstream omyfile;
       
                omyfile.open("C:/Documents and Settings/&#37;USERNAME%/Local Settings/Temp/test.txt");
                getline (omyfile,line);

                omyfile.close();

        ofstream imyfile;

imyfile.open ("C:/Documents and Settings/%USERNAME%/Local Settings/Temp/test.txt");
       
                imyfile << test<<line;
                imyfile.close();

        return 0;

};

ok i think problem is somthing to do with %USENAME%
thx

In part. You need to interrogate the system for the current user name (look up GetUserName() in the win32 SDK). "..../%USERNAME%/Local Settings/Temp" is also a directory; you need to append a filename to the path.

Use boost filesystem or do what grumpy said.

ok ty

i found this

Code:

---

HRESULT GetUserName(
    BSTR *pbstrUserName
);

---

but im not really sure how i use it
plz can som1 explain it for me, sorry

GetUserName() in the win32 SDK has two arguments (a pointer to a buffer that will receive the username, and the length of that buffer) and returns a BOOL (zero for failure, non-zero for success). You are presumably using some other library.

The username needs to be substituted in where you have %USERNAME%, and (for example) a filename named file.dat needs to be appended on the end of the path (so if the user is "grumpy", the filename will look like "C:/Documents and Settings/grumpy/Local Settings/Temp/filename.dat"

ok


when compiling i get the following error
error C3861: 'GetUserName': identifier not found

is this because i havnt got
#include <windows.h>

if i add that
i get this error
fatal error C1083: Cannot open include file: 'windows.h': No such file or directory

is this because im using the visual C++ express edition ?

Could be; I've never used the express edition, so don't know its shortcomings relative to the flagship products.

You may need to specifically specify the include path which contains <windows.h>. I don't know how to do this with Microsoft compilers. On the other hand, maybe that compiler doesn't even have those functions.

You could always try a different compiler. :)

Yes - You need to instal Windows SDK and add paths of SDK include, library and executable directories to your IDE settings -

ok ty i will look into getting a diffrent complier

>> ok ty i will look into getting a diffrent complier

Why? Just finish installing the VC++ Express. Part of the installation process is to download the SDK separately.

because im asuming that with other compliers you will be also allowed to make win32 applications

with this i can only make win32 console applications and windows forms applications

No, you can also make Win32 windows applications without forms.

? do you mean WIN32 console applications,
i know you can make them

there is no WYSIWYG is there?

I think you're looking for a resource editor, which VC++ has. I'm not sure about express, though.

No, I mean Win32 windows applications...

Of course, there isn't WYSIWYG in Win32 windows apps. You used to be able to use the class wizard to build MFC apps, but MFC is not supported in VC++ Express.

I might be wrong and maybe regular windows apps are only supported in the non-Express versions. I honestly haven't done it myself. However, I'd be surprised if that was the case since you should be able to download the Win32 windows library and once you have the library you should just be able to use it.

nope i can only make "win32 Console application" with Express :(

Have you done all of these steps, including #5 which seems to indicate that it is possible but it starts off disabled?

oops sorry
no i dont think i have

Express is for console, Win32, OpenGL or DirectX (hence Win32). No MFC support.
