nsDialogs IP Address Control
I'm trying to create an IP Address Control using nsDialogs and not having much luck.

No matter what I do I can't get a handle back other than 0, can someone let me know what I'm doing wrong?

Here's the code:

!define ICC_INTERNET_CLASSES 0x00000800

nsDialogs::Create 1018
Pop $Dialog

StrCmp $Dialog "error" 0 Start
Abort
Start:

System::Alloc 400
Pop $R0

StrLen $1 "${ICC_INTERNET_CLASSES}"
System::Call "*$R0(i r1, i ${ICC_INTERNET_CLASSES})"
System::Call 'comctl32::InitCommonControlsEx(iR0)i.R4'

nsDialogs::CreateControl "WC_IPADDRESS" "${DEFAULT_STYLES}|${WS_TABSTOP}|${WS_CHILD}" "0" 5% 88% 40% 12u ""
Pop $1
messagebox mb_ok $1
System::Free $R0

nsDialogs::Show

its not StrLen, but the size in bytes of the structure, try:
System::Call "*$R0(i 8, i ${ICC_INTERNET_CLASSES})"

also, WC_xxx is a define, so, make sure there is a define with that name and put ${ } around it, or just use "SysIPAddress32"

Just cross-referencing this thread to a recent thread that discusses a font problem that can occur when using the SysIPAddress32 control 'as is'. Short summary: you must create a new font and set it on the IP address control before use to prevent corruption of your installer font.
