How to stop a macro at a Shell line.

[Alex St-Pierre]

Hi,
The following macro run until the language inside the control panel has not
been set to english. The problem I have is that "Shell Cmdl$, vbNormalFocus"
show a box but the macro run during that time. If the language is not set to
english before the macro start, Shell Cmdl will be shown 2 times (instead of
one) even if the language is set to english when the first box is shown. What
happens is that before the user choose the value (first time) "Shell ...",
the macro run and the new parameters are set to old value. Any idea?
Thanks!
Alex
Sub test()
512 = GetUserDefaultLCID()

iRet1 = GetLocaleInfo(Locale, LOCALE_SENGLANGUAGE, lpLCDataVar, 0)
Symbol = String$(iRet1, 0)
iRet2 = GetLocaleInfo(Locale, LOCALE_SENGLANGUAGE, Symbol, iRet1)
'GetLocaleInfo(Locale, LOCALE_SDATE, Symbol, iRet1)
pos = InStr(Symbol, Chr$(0))
If pos > 0 Then
Symbol = Left$(Symbol, pos - 1)
sLang = Symbol
End If
If sLang <> "English" Then
MsgBox ("The regional settings must be English." & Chr(10) &
"Your currently setting are " & sLang & ". Please select English in the next
box")
Cmdl = "rundll32.exe shell32.dll,Control_RunDLL intl.cpl" + ",,5"
Shell Cmdl$, vbNormalFocus
GoTo 512
End If
End Sub

Thank Tom!
Using the second link, I modify one line (program executed) and all works!!
