i get errors

c:\Documents and Settings\Administrator\My Documents\Visual Studio Projects\C++\php_format\php_format.cpp(52): error C2784: 'std::basic_istream<_Elem,_Traits> &std::getline(std::basic_istream<_Elem,_Traits> &,std::basic_string<_Elem,_Traits,_Alloc> &)' : could not deduce template argument for 'std::basic_istream<_Elem,_Traits> &' from 'ifstream'


c:\Documents and Settings\Administrator\My Documents\Visual Studio Projects\C++\php_format\php_format.cpp(44): error C2872: 'ifstream' : ambiguous symbol

bah?

ifstream ifile; 
    ifile.open(argv[1]);

    if(!ifile){
        printf("Could not open file, or file does not exist!\n");
        return exit();
    }

    while(getline(ifile, sTmp))
    {
        //validate stuff in here
        printf("%s\n", sTmp.c_str());
        printf("%c",istag(sTmp.c_str());

        //sFile += sTmp + '\n';
    } 

istag() is a seperate function i wrote

[nabeels786]

hmm

when i do


while(getline(ifile, sTmp))


it says "2 arguments specified, 3 needed"

while(getline(ifile, sTmp, '\n'))

it says "3 arguments specified, 2 needed"

[nabeels786]

ok fixed the other errors

what does "error C2872: 'ifstream' : ambiguous symbol
" mean?

Did you include <fstream> ?

[nabeels786]

yup.

im using vc7 if that helps

[SteveCRM]

if you have #include <fstream> you'll need
using namespace std;

otherwise you'll have to use fstream.h

I've always used .h, works for me

don't know how much help this is but,

[nabeels786]

i tried both, no go

[SteveCRM]

can you post the whole source if its not that long? so I can put it in VC++ and try to get it

[nabeels786]

ifstream ifile;                                        //file stream var

    ifile.open(argv[1]);

    if(!ifile){
        printf("Could not open file, or file does not exist!\n");
        return exit();
    }


    sFile="";
    while(ifile.getline(input,255,'\n') && !ifile.eof()) {
        debug(input);    //DEBUG

        if(istag(input)=='h'){    //its an HTML tag
            sTmp = "<?";
            strreplace(input,"\"","\\\"");    //replace " and ' with \" and \'
            sTmp += input;
            sTmp += "?>";
        }
        sFile+=sTmp + '\n';
    }

[SteveCRM]

the problem is on this line

strreplace(input,""","\\""); //replace " and ' with \" and '

you can't say " " ", it thinks the second one is ending the string. To make it ignore any character, put \ in front of it, so """ can now be "\"", this will make a quote in the string

[nabeels786]

the php formatting thing took it out. i have the backslash there though.

it says the error is in ifstream ifile.

heres that whole if:

if(istag(input)=='h'){ //its an HTML tag
sTmp = "<? echo \"";
strreplace(input,"\"","\\\""); //replace " and ' with \" and \'
sTmp += input;
sTmp += "\" ?>";
}

Should always use <fstream>, .h won't work at all very soon (just try using it with VC7, it complains bitterly

[SteveCRM]

noooooooooooooo hehe gotta start using that

oh maybe this then?

you need to set what file
ifstream ifile(yourfile, opentype);

most popular open types are ios::trunc, ios::app (truncate, and append)

[nabeels786]

alright, i did clean buld, and rebuilt it, now it doesnt complain about that

now its

[parksie]

You've got some mismatched quotes/backslashes somewhere, I think.
