Wierd Function arguments - % and $ [RESOLVED]

Hi, what is up with those special characters?

VB Code:

Public Function OpenLab(ByVal LabFile$) As Boolean

and

VB Code:

Public Function PrintLab(ByVal Num%) As Boolean

What do they do?

Its old VB for declaring the var type.

$ = string
% = int

Has something to do with data types, I don't remember what symbols go with which data types though =/

Edit
Listen to the above =)
Didn't see his post when I sent mine.

Edit 2
Wow, now listen to the undersigned as well =)

THey are data types....

DIm Boo$
Dim Boo%
Dim Boo&

$ = string
% = integer
& = Long

VB Code:

Public Function OpenLab(ByVal LabFile as string) As Boolean 'Public Function OpenLab(ByVal LabFile$) As Boolean
Public Function PrintLab(ByVal Num as integer) As Boolean 'Public Function PrintLab(ByVal Num%) As Boolean

:wave:

OK I kinda figured it was something like that. I used to program in QBASIC and numerals were suffixed in '#' and strings were suffixed in '$'.

Thanks all!

for the record your fellow programmers will shoot you if you use them now

I wonder If I can get away with a global search and replace:

Replace "$"
With "As String"

The replace might not be a good idea, what about the mid$ function, than would look : mid as string (str1,2,5).....

Code:

---

$ = String
% = Integer
& = Long
! = Single
# = Double

---

Only the extra 2 :p

Phreak

no a global search and replace would be a BAD idea

You can reference the strings like this

VB Code:

Dim MyString$
MyString$ = "HELLO WORLD"

which after your replace would look like

VB Code:

Dim MyString As String
MyString As String = "GOODBYE WORLD"

In the code, the suffixes were not used. Only on the Dim... line or in the argument line.

After his replace wouldn't it look like this:

VB Code:

Dim MyString As String
MyString As String = "HELLO WORLD"

yup except it would be "goodbye" cause the code wouldnt compile ;)

VB Code:

Dim MyString As String
MyString As String = "GOODBYE WORLD"

Then it should be:

VB Code:

Dim MyString As String
MyString As String = "GOODBYE CRUEL WORLD"

speaking of cruel, i have to convert a QBasic program myself and there about 200 variables, all declared at a global level, and they are all 1 or 2 digit names

Dim a1$
Dim a2$
etc....

oooo that is going to be fun :( :( :(
