reading from a file 1

[jl3574]

i created an simple binary query database with an interface and a simple import file button
however i need to keep trace how many times a file is being imported as when time the button pressed the program will terminate. since i can't keep a count using a varaible inside the program cause variables reset after the program terminates i was thinking of using another file to keep track with an array or somthing? and each time the program runs it would check which file number i'm at? so how would i code this? or is there a better way?
pls help...

You can use the CFile class to read files.
Here is a little example:

CFile file;
int filenum;

//if not exist, create.
if (file.Open( "filenum.dat", CFile::modeReadWrite))
file.read(&filenum, sizeof(int));
else
{
file.Open( "filenum.dat", CFile::modeCreateCFile::modeReadWrite);
filenum = 0;
}

// enter your code here
// when you close the program, write the variable to
// the file
file.Write(&num, sizeof(int));
file.Close();
