question about opening files with fstream

[cmccmc]

im trying to open a file located at C:\Users\*USERNAME*\AppData\Roaming\FileZilla
The problem is everyones username is different so I used

char homedirectory[MAX_PATH];
SHGetFolderPathA(NULL,CSIDL_PROFILE,NULL,0,homedirectory);

to get the home directory.My problem is well I don't know how to explain it. It would probably look like this but this obviously isn't allowed
filestr.open(homedirectory"/AppData/Roaming/FileZilla/sitemanager.xml",fstream::in);
How could I do something like that?

Consider the .c_str() function, and using strings.

Once you get the string that is the home directory, something like this could work:

//psuedo/incomplete
string homedir = gethomedir();
fopen( homedir.c_str() + "rest/of/path" );

can you give me an example?

What is that Desh? Appending to char * with operator+??
Sorry saw your comment too late.

Do this (or similar)

//do what you did before and then
std::string hd(homedirectory);
hd += "/AppData/Roaming/FileZilla/sitemanager.xml";
filestr.open(hd,fstream::in);

I get an error when doing that. Heres my complete code

#include <fstream>
#include <iostream>
#include <string>
#include <Shlobj.h>
using namespace std;
int main()
{
	char homedirectory[MAX_PATH];
	//Retrieves Users Home Directory
	SHGetFolderPathA(NULL,CSIDL_PROFILE,NULL,0,homedirectory);
	fstream filestr;
	string filelocation(homedirectory);
	//Starts Filezilla Password Recovery
	filelocation+="/AppData/Roaming/FileZilla/sitemanager.xml";
	filestr.open(filelocation,fstream::in);
	filestr.close();
	return 0;
}

and the error is

You need to convert the std::string to a C string. Like this:

filestr.open(filelocation.c_str(),fstream::in);

thanks that worked

Yea, quickly did that to get the point accross. I meant to create the string, append the "rest_of_dir" to it, THEN convert it to a c style string using c_str().
