Application Security Testing: An Integral Part of DevOps
Entry (position,txt,delim) Numentries (txt,delim) ParseCommandLine ()
The Entry function is usefull in many other areas. If you had a string that was "a/b/c/d" and you wanted to find out what the 3rd entry was you would use:
x$ = entry(3,"a/b/c/d","/") ' x$ would = "c". x% = NumEntries("a/b/c/d","/") ' x% = 4.
Run the ParaCommandLine from the main Form to set variables or actually run the various requests from the command$.
public Function Entry(byval Position as Integer, byval Txt as string, _ byval Delim as string) as string 'This function is the same as Progress' Entry function on error resume next Dim CurrentPosition as Integer, StrStart as Integer, _ StrEnd as Integer, StrCntr as Integer StrStart = 1 CurrentPosition = 1 Txt = Txt & " " 'add a space to the end of the string for StrCntr = 1 to len(Txt) If mid(Txt, StrCntr, 1) = Delim Or StrCntr = len(Txt) then StrEnd = StrCntr - 1 If StrEnd - StrStart < 0 then Entry = "" StrStart = StrCntr + 1 If CurrentPosition = Position then Exit Function else Entry = Trim(mid(Txt, StrStart, StrEnd - StrStart + 1)) If CurrentPosition = Position then Exit Function StrStart = StrCntr + 1 End If CurrentPosition = CurrentPosition + 1 End If next End Function public Function NumEntries(byval Txt as string, _ byval Delim as string) as Integer on error resume next Dim StrCntr, DelimCntr as Integer DelimCntr = 1 for StrCntr = 1 to len(Txt) If mid(Txt, StrCntr, 1) = Delim then DelimCntr = DelimCntr + 1 next StrCntr NumEntries = DelimCntr End Function
The following sub can be placed on any form (usually them main form/module).
