String handling

I am using two different platforms mainframes(CICS) and VB.
Connecting VB to CICS

I want to move spaces to a string variable at run time. The no .of spaces are also vary .

Unless I'm totally missing the plot here

VB Code:

Option Explicit
 
Private strSpaces As String
 
Private Sub Form_Load()
    strSpaces = String(45, " ")
End Sub
