Hello,

I use a functions of a DLL. When the type is badly declared, openoffice crashes.

--------------------
Module which works:

Option Explicit
' The DLL function is properly declared with the type "Long"
Declare Function ibdev_nocrash Lib "Gpib-32.dll" Alias "ibdev" (ByVal bdid As
Long, ByVal pad As Long, ByVal sad As Long, ByVal tmo As Long, ByVal eot As
Long, ByVal eos As Long) As Long

Sub No_Crash()
    Dim SFQ As Long
    Dim Const AddSFQ As Long = 8 'IEEE address SFQ
    SFQ = ibdev_nocrash(0, AddSFQ, 0, 13, 1, 0)
End Sub

--------------------
Module which gives rise to crash:

Option Explicit
' The DLL function is badly declared with the type "String" instead of "Long"
Declare Function ibdev_crash Lib "Gpib-32.dll" Alias "ibdev" (ByVal bdid As
Long, ByVal pad As Long, ByVal sad As Long, ByVal tmo As Long, ByVal eot As
Long, ByVal eos As Long) As String

Sub Crash()
    Dim SFQ As String
    Dim Const AddSFQ As Long = 8 'IEEE address SFQ
    SFQ = ibdev_crash(0, AddSFQ, 0, 13, 1, 0)
End Sub

I try to attach a test file (.sxc) and the appropriate DLL.
Cheers!
