IP control

Does anybody have handy IP control which allows to input only valid IP thus making unnecessary complicated checking?

It's a pity that nobody answered. Here is my solution which is just silly checking of a string entered in text box:

Var IpToCheck

Var IpSectionsCount ; every IP consists of 4 sections

Function CheckIsIpValid

  Pop $IpToCheck ; trimmed ip



  StrCpy $IpSectionsCount 0

  ${Do}

    Push "." ; divider char

    Push $IpToCheck



    Call SplitFirstStrPart

    Pop $1 ; first IP number

    Pop $IpToCheck ; the rest of IP string



    Push $1 ; verify if numeric

    Call IsNumeric

    Pop $0



    ${if} $0 == 0

      goto invalid_ip

    ${else}

      ${if} $1 < 0

        goto invalid_ip

      ${endif}

      ${if} $1 > 255 

        goto invalid_ip

      ${endif}

    ${endif}

    IntOp $IpSectionsCount $IpSectionsCount + 1

  ${LoopUntil} $IpToCheck == ""



  ${if} $IpSectionsCount == 4

    Push 1 ; OK, valid IP

  ${else}

    goto invalid_ip

  ${endif}

  Return



invalid_ip:

  Push 0 ; Invalid IP

FunctionEnd

The code does not verify a lot of things like that first section is not 0 but suits for most of situations.

InstallOptionsEX has custom page function for IP addresses. It may work for what you need.

Also, Check IP might be an alternative way to check an IP address.

I've tried CheckIP but it is a bit obscure. It seems that is really checks ip (not just ip number correctness) which is sometimes not needed in an installer.
I will try to see InstallOptionsEx, thanks!

Heh, I thought I was the only one looking for this. I haven't found a workable solution yet. For some reason, InstallOptionsEx has some trouble displaying my InstallOptions pages. (And it doesn't help that the project is abandoned 🙁).

Anyway, I know I posted a bit later than you but I figured the screenshot in mine might help.

Well... I recommend using the function to verify the IP. The control is buggy, just like everything else in the plug-in.
