hello everyone Help anyone with what they can.
How do I access a file for example that is located on ” c: est.txt”
Read it, change the 1st line and save and close? Using a simple mql5 expert Advisor.
I will be sooo grateful.
Thanks!

If only..
When using
string TmpFileName(string Name,string Ext){
string fn=Name+"."+Ext; / / formed name
int n=0;
while(FileIsExist(fn)) { // if the file exists
n++;
fn=Name+IntegerToString(n)+"."+Ext; / / adding a number to the name
}
return(fn);
}
Hits an error in: (although the script is clean)
string TmpFileName(string Name,string Ext){
