I got 2 forms:
form1
and
form2

in form1 I tell it to make a file called C:\b.dat

in form2 I tell it read from the file c:\b.dat at form load

As soon as I run the program it says

error 51, file not found

it says that because the file doesn't exist yet

so what do I do

if you dont know what I mean, I could try to explain it another way
