Problem reading information from an Array saved to file

[PeterRanson]

Hi,

im having problems reading information out of a .dat file that an array has been saved into. i have two two dimensional Arrays,

int GridTracker[100][15];
int GridStatus[10][10];

i have a funtion that is writing that infomation to file

void write_arrays() // write data to a file to backup memory
{

int pgt,pgs;

pgt=FileOpen("panther-gt.dat", FILE_BIN|FILE_WRITE);


if(pgt>0)
{
Print("wrirte ", FileWriteArray(pgt, GridTracker, 0, 1500));
FileClose(pgt);

}
pgs=FileOpen("panther-gs.dat", FILE_BIN|FILE_WRITE);
if(pgs>0)
{
Print("write ", FileWriteArray(pgs, GridStatus, 0, 100));
FileClose(pgs);
}
}

when this function runs, the result of the FileWriteArray is 1500 and 100. i.e. the size of the arrays.

i have another function which then reads from the file

void read_arrays() // read data to a file to backup memory
{

int pgt,pgs;

pgt=FileOpen("panther-gt.dat", FILE_BIN|FILE_WRITE);


if(pgt>0)
{
Print(FileReadArray(pgt, GridTracker, 0, 1500));
FileClose(pgt);
Print(GetLastError());
}
pgs=FileOpen("panther-gs.dat", FILE_BIN|FILE_WRITE);

if(pgs>0)
{
Print(FileReadArray(pgs, GridStatus, 0, 100));
FileClose(pgs);
}
}

the result from both operations is zero, i.e. no items read. the result from GetLastError() is also zero, and the result from the FileOpen operations is 1 i.e successfull.

this has me completely stumped, any ideas?

Isn't is just that, in read_arrays(), you're opening the files with FILE_WRITE rather than FILE_READ? Reading and writing multi-dimensional arrays using FileReadArray() and FileWriteArray() does work.

LOL thankyou ... i had not spotted that. working fine now. sometimes you just need a second set of eyes!
