FilesExist - check if a file exists in web folder

[Rubens Marinho]

Here:

http://docs.mql4.com/files/fileisexist

There are the instruction to handle files (down/up, read-writhe ...)

I'm trying to code this to check if a file exists in web folder...

Any idea how to do that?

What is "web folder" ?

Anyway, mql4 file functions only work in the sandbox : all what is under MQL4\Files

[Rubens Marinho]

I mean with a web folder:

http://www.domain.com/folder/file.bak

The idea is verify if a file exists in web folder, and, if yes the EA will grant the trades, for example:

//+------------------------------------------------------------------+

//+------------------------------------------------------------------+
#property copyright   "2005-2015, MetaQuotes Software Corp."
#property link        "http://www.mql4.com"

extern string file_user = "file.bak";

int start() {

if (  file_user()!= http://www.domain.com/folder/)
   {
    Alert("WRONG FILE!");
   return;
   }

And my doubt is, how can I check that?

You have to use WebRequest().

Yes, I saw and tried here:

But, I wasn't able to code it... could you please help me?
