VB Api declaration: SymGetSymFromAddr64

Merrion

I am having problems with the declaration of this API call.

I have :-

Private Type ULONG_64
    byte0 As Byte
    byte1 As Byte
    byte2 As Byte
    byte3 As Byte
    byte4 As Byte
    byte5 As Byte
    byte6 As Byte
    byte7 As Byte
End Type

Private Type IMAGEHELP_SYMBOL64
  SizeOfStruct As Long
  Address As ULONG_64
  size As Long
  Flags As Long
  MaxNameLength As Long
  Name As String
End Type

'BOOLEAN SymGetSymFromAddr64(
'     IN  HANDLE              hProcess,
'     IN  DWORD64             qwAddr,
'     OUT PDWORD64            pdwDisplacement,
' '    OUT PIMAGEHLP_SYMBOL64  Symbol
Public Declare Function SymGetSymFromAddr64 Lib "dbghelp.dll" ( _
               ByVal hProcess As Long, _
               qwAddr As ULONG_64, _
               pdwDisplacement As ULONG_64, _
                Symbol As IMAGEHELP_SYMBOL64) As Long

but when I call it I get an error Bad DLL Calling Convention which means my declaration is putting too little or too much on ths stack.

Any ideas?

Changing to

Byval qwAddr As Currency

seems to have improved things - I'm now getting a The specified module could not be found error but that's presumably because it can't find the debug info for my system dlls.
