I can't figure out if I am doing something wrong, or this is messed up. When I just do this


dbOpenToWrite(1,"test.txt");
dbWriteFloat(1,1000);
dbCloseFile(1);


and in test.txt it looks like this

zf

or something very close.

As far as dbReadFloat goes, I'm not having any luck either. If I do this

char *test;
dbOpenToRead(1,"test.txt");
test=dbReadFloat(1);
dbCloseFile(1);

then I come up with an extremely large number that is no where close to what it actually was.

I would just like to know what's going on here. Thanks

It is possible the readFloat function doesn't work, but why are you using dbReadFloat like that ?

I've just tested this myself and dbReadFloat works fine, but it returns a float not a char *. The dbRead/WriteFloat commands read and write the internal binary format of a float variable, not the text representation of it, that's why it's not readable in the text file either.

Wow. You guys are using SDK file I/O, when you have the choice of using the standard C, C++ or Windows file I/O?

Wow, again.

I was just pointing his/hers/its dodgy use of functions - the time for bringing them around to using stdio i/o functions is later on

Oops. that was just me not think right while typing that. I am not actually using char*.
I will definatly not use the sdk file i/o if it's crap. Thanks for pointing that out for me.

Theres nothing particularly wrong with the SDK I/O system - all it seems to call is fread/fwrite (or possibly _read & _write), so why waste a few milliseconds and not call the standard file routines yourself ?
