Strings as parameters

Dear all,

I would like to pass a string as parameter to a form that would modify it. Then, as a result, I would like, when finish the form, to change this variable.

Observe that the I will need to access the parameter in many subs and functions before it is ready to be returned.

I am thinking use pointers to this string to have how to modify it?
How can I do it?

If I pass a Label.Caption as parameter, could I modify it on a function?

Thanks in advance,
Nizam

Why did you post the same post twice?

I didn't know that VBForums and VBExtreme was the same site and I was wanting to publish my doubt in many places to have a fast answer. Do u know how to solve this problem frd?

Label.Caption = sCaption

then sCaption variable can be changed in a function or sub you just need to declare it at very top of your code in Declarations area... -.- or module.......

But when I do this and change sCaption I will not change Label1.Caption, will I?
Actually I would like my form woks like a function.

Anyways, usually you would use ByRef, but apparently you can't for the Caption property. You can still do something like this though:

VB Code:

private sub Whatever(byval SomeStr as String)
SomeStr="hello"
end sub
 
'in another procedure
dim tmp as string
 
tmp=Label1.Caption
whatever tmp
Label1.Caption=tmp

ByRef or ByVal? Because I want to pass the reference as parameter and not the value, right?

Dbl posting is a bad habit.
