Need to get the last bit of a string

[Afrow UK]

I have a path entered by the user which may be:

C:\quake2\baseq2\maps\gbrdday1.map

How can I get the gbrdday1.map bit.
Note that it could be anything, not at all gbrdday1.map

Basicly, the bit after the last \ is what I want.

You can tweak GetParent to do the trick. And if you don't want to handle the code too much you can get the length of the returned string and trim up to that point using StrCpy with a negative maxlen.

Here is the script:
I'm not sure how to return it to Exch, Pop and Pushing the variables around, so I've left it as this.
KiCHiK, please show me what the basec Pop, Push and Exch cmds should be.

Usage:
StrCpy $R0 C:\Geoffrey\Freddy
Call GetFileName
DetailPrint $R3 # $R3 is now Freddy

code:


Function GetFileName

   StrCpy $R1 -1

   loop:

     StrCmp $0 1 +2

     IntOp $0 $0 + 1

     StrCpy $R2 $R0 1 $R1

     StrCmp $R2 "" exit

     StrCmp $R2 "\" exit

     StrCpy $R3 $R2$R3

     IntOp $R1 $R1 - 1

   Goto loop

   exit:

 FunctionEnd

Thanks

Haven't tested it but it should work:

PHP Code:

Function GetFileName
  Exch $0 ; input string
  Push $1
  Push $2
  StrCpy $1 0
  loop:
    IntOp $1 $1 - 1
    StrCpy $2 $0 1 $1
    StrCmp $2 "" exit_dec
    StrCmp $2 "\" exit
    Goto loop
  exit_dec:
    IntOp $1 $1 - 1
  exit:
    IntOp $1 $1 + 1
    StrCpy $0 $0 "" $1
    Pop $2
    Pop $1
    Exch $0
FunctionEnd
