quick VB question (Please Help)
Author
Okay...
I want to read in one five-digit Integer and determine how many digits in the Integer are 7''s. I was wondering if there is a VB function for this????
Not really. But you can do this:
Public Function count7(Num as integer) as integer Dim strNum as string, i as integer, cnt as integer strNum = Str(Num) For i = 1 to len(strNum) If mid(strNum, i, 1) = "7" then _ cnt = cnt + 1 Next i count7 = cntEnd Function
Or even further, you can do this..
This will probably work faster.

Public Function count7(num as integer) as integer Dim strNum as string, i as integer, i2 as integer strNum = str(num) i = instr(strNum, "7") While Not (i=0) i2 = i i = instr(i+1, strNum, "7") Loop count7 = i2End Function This will probably work faster.

why not use do until instead of while not?
do until (i=0)
or even "while i" should work properly... since anything not = 0 SHOULD be true (I think VB handles this properly).
Also, i think Sporty messed up.. he put i2 = i, where he really meant i2 = i2 + 1

Yes you''re right, I forgot that part
I only use While Not because I''m simply more used to reading it that way. Seems a bit clearer when I''m quickly browsing old code. Just a preference.

I''m actually used to using while not also (as that''s what we get in C/C++ while loops), but in VB I prefer to use until as it makes it very easy to read.. do until x = 0... just as simple (if not simpler) to read as do while not (x=0)... but again, just personal preference.
