How to the id:5002 problem of FileOpen? - page 2

New comment

Good afternoon. I've got similar problem above. But the problem is, when I just put the filename, I got error 5004. If I specify the path I got 5002. Did I miss something here?

string filename = TerminalInfoString(TERMINAL_DATA_PATH)+"\\MQL4\\Files\\output.txt";
//Print(filename);
ResetLastError();
int file_handle=FileOpen("output.txt", FILE_TXT|FILE_READ);
//Print(file_handle);
string up, down, sideway;
up = down = sideway = 0;
if (file_handle!=INVALID_HANDLE){
   Print("read");
   up=FileReadString(file_handle);
   down = FileReadString(file_handle);
   sideway = FileReadString(file_handle);
} else{
   Print("file open error: ", GetLastError());
} FileClose(file_handle);
I put the file in Files folder. I've checked it's indeed the file is exist as specified in the filename string.

Once again :

Thanks, just want to check can i write my files in a subfolder in this common folder.. 


Example

Right now it is creating files in " C:\Users\******\AppData\Roaming\MetaQuotes\Terminal\Common\Files


i want files in 

C:\Users\******\AppData\Roaming\MetaQuotes\Terminal\Common\Files\1

C:\Users\******\AppData\Roaming\MetaQuotes\Terminal\Common\Files\2

I think i solved it..


this is working

   filename1 = "//1//"+"Summary.csv";

  filehandle1=FileOpen(filename1,FILE_COMMON|FILE_WRITE|FILE_CSV);
