hi,
i am trying to call a function and use the returned value as the value of a string (using vba). Apparently it is not working. For example,

Function myFunction(name As string) As String
...
end Function

Sub mySub()
dim stName As string
stName = myFunction(something) ///error
' or
stName = Call myFunction(something) ///error
end Sub

Please let me know how to solve this problem

thanks
Sanjana

Here is an example similar to yours:

Option Explicit

Private Sub Command1_Click()
    mySub
End Sub

Public Function myFunction(ByVal name As String) As String
    ' do something with name and return it
    myFunction = Left(name, 1) & Right(name, 1)
End Function

Public Sub mySub()
    Dim stName As String
    Dim stParam As String
   
    stParam = "something"
    stName = myFunction(stParam)
    MsgBox "Input: " & stParam & vbCrLf & "Output: " & stName
End Sub

where you have written this code. Just create a simple application (standared exe application) in vb6. now call your mysub function in form onload event like this

Private Sub Form_Load()
    Call mySub ' here is your function call
End Sub

Function myFunction(name As String) As String
    myFunction = name
    '...
End Function

Sub mySub()
    Dim stName As String
    stName = myFunction("something")
    MsgBox stName
    ' or
    stName = myFunction("something")
    msgbox stName

End Sub

Should the line
stName = myFunction(something)
be
stName = myFunction("something")
instead?

I don't know what you need to know !
I hope that yuo know a function returns a value and a sub does something. Either one can  have parameters (arguments)
=============
Here is a sample:
Private Sub Command1_Click()
mySub
End Sub

Function myFunction(name As String) As String
myFunction = "Hello " & name
End Function

Sub mySub()
Dim stName As String
strName = "John"
stName = myFunction(strName)
MsgBox (stName)
End Sub

vbCrLf stands for Visual Basic Carriage Return & Line Feed.  When used in a string it causes the cursor to move down to the next line allowing you to make multiline messages.
