ok

i really need help here. i need a way to load variables from a file.

for example, if i have a file that looks like this:

size=10
weight=25
color=1

how can i load that file into dbpro to define those variables.

ive got it to where i can load it into an array (thanks Xmik) like this:

+ Code Snippet

opendiag$=openDialog("Open FPE"," (*.fpe)|*.fpe")


open to read 1,opendiag$


dim file() as string



array insert at bottom file(0)
read string 1,file(0)

while file end(1)=0
   array insert at bottom file(0)
   read string 1,file(array count(file(0)))
endwhile

for x=1 to array count(file(0))
   print file(x)
next x

and it prints fine. but, how do i make those values useful?

i thought i would use a memblock, but im not quite sure how.

First, you should save these to the file:
10
25
1
You do not need the variable at the front, and it makes it hard to load.
Then use this code(DBC, but I think this will work in DBP)

+ Code Snippet

Open to read 1,"Save.dat"
   Read string 1,Size$
   Read string 1,Weight$
   Read string 1,Color$

   Size = val(size$)
   Weight = val(weight$)
   Color = Val(color$)
Close file 1

Hope it helps

thats what i wanted to avoid.

my files are editable by the user,
and they arent always in the same order, plus, when my users open the file, i dont want them to see a list of numbers, they need to be able to make sense of the program.

like i have posted abpve, i already have a way to load things into an array, if thats what i wanted to do. but i want my users to define variables, not list numbers.

but thanks for trying to help.

You could have it like this:
Size:
10
Weight:
25
Color:
1
and just load the labels into the junk$ variable, or any other variable that has no use.

but what if they were in a different order than the original file?

the values would all be messed up.

i need a way to compare the variables to hard codded ones, or let the file define all the variables.

i know it seems stubborn, but i need it to be this wy.

UFO's last suggestion is fine. The format is

NAME
VALUE
NAME
VALUE

It doesn't matter if you switch the variables around, as long as they are in pairs.

+ Code Snippet

WHILE NOT FILE END(1)
   READ STRING 1, name$
   READ STRING 1, value$

   SELECT name$
      CASE "WEIGHT"
        DoSomethingWithWeight(value$)
      ENDCASE

      CASE "HEIGHT"
        DoSomethingWithHeight(value$)
      ENDCASE

      ` etc...

Sorry, but I didn't understand most of what you were asking before, so I can't get exactly what you want unless you explain it well. I didn't know you wanted the user to be able to put the pairs in different areas, but BatVink has a good way to do that.

Here's my classic level format:

+ Code Snippet


SLOT>32
POSX>32
POSY>16
POSZ>24
SIZEX>2
SIZEY>16
SIZEZ>2

The code:

+ Code Snippet

repeat
read string 1,command$
if left$(command$,5)="POSX>" then posx# = val(right$(command$,len(command$)-5))
and so on
until file end(1)

At least farting ferrets are better than stinky stoats.

The FPE files are text files and yeah the info is stored like so

size=10
weight=25
color=1

so pretty much you're down to parsing text, by line. Try what Ferret's got, should work.

thast what i was doing in the first place, i just posted here to see if there was an easier way...

so that means i have to manually type that out for every single command.

it also is going to lengthen the code quite a bit, not to mention take a long time.

but thanks everyone for theire help.
i appreciate it.

regarding the code in the first post of this thread, to get the file lines into an array: iirc Load Array() does this in one call, but I dont have dbp installed so I cant check on that. You may want to check that out.

SORRY UR NOT COMEDIAN
