Help me with a function that checks if a variable in an .INI exists!

Lol, well this is making me pretty mad. Im trying to make a function that checks if there is a variable within an ini.

I tried something like:

public function CheckINIVar (EventName as string) as boolean

  dim a as integer

  on error goto Error

    for i = 0 to 10

    if getvar(app.path(blah blah blah),header,EventName) = i then    <– Eventname is the name of the var it looks for
      CheckINIVar = true
      end if

  Error

end function

but this always returns false, since getvar returns a string and a for loop must use integers in the var. so strings cant = integers (duh)

so, to fully explain it: This function needs to return TRUE if there is a variable named whatever EventName in CheckINIVar (EventName as string) is. and if there is not a variable named that then it returns a FALSE.

anyone got an idea?

val(string) might work

nvm, i was being dumb. I overlooked a really simple way to do it, instead i just did:

  Public Function CheckEvent(EventName as string) as boolean

  if getvar(blahblahblah,blah,EventName) = "" then
    CheckEvent = false

    else
    CheckEvent = true
      end if

end function.

lol, i forgot that when the variable isnt found it returns a vbnullstring.

if getvar(…) = vbnullstring should work too...

vbnullstring is even better :)

yay! im getting smarter!

i usually use vbnullstring to figure out if im starting something new so i thought it was the best way.
