Run-Time Error 49: Bad Dll calling Convention

[PatVB]

I am trying to call in into a c++ dll:

GetLibInfo(LPCTSTR libName, long* numEntries, long* numPoints, HANDLE* hLibComment, double* firstX, double* lastX, DATAXTYPE* pxtype, DATAYTYPE* pytype, long* bBaseline, long* libIsATR, long* bReadonly, LIBBYTES* libBytes)

From the vb module, I did this:

Public Declare Function GetLibInfo Lib "DLSLibSearch_ur.dll" (ByVal LibName As String, ByRef numEntries As Integer, ByRef numPoints As Integer, ByRef hlibComment As Integer, ByRef FirstX As Double, ByRef LastX As Double, ByRef DataXtype As Integer, ByRef DataYtype As Integer, ByRef bBaseline As Integer, ByRef libIsAtr As Integer, ByRef bReadonly As Integer, ByRef LibBytes As Integer) As Long

And when I call the function in a form, i get the error message

Private Function getInfo(ByVal LibName As String) As Long
    Dim numEntries As Integer
    Dim numPoints As Integer
    Dim hlibComment As Integer
    Dim FirstX As Double
    Dim LastX As Double
    Dim DataXtype As Integer
    Dim DataYtype As Integer
    Dim bBaseline As Integer
    Dim libIsAtr As Integer
    Dim bReadonly As Integer
    Dim LibBytes As Integer
    
    Dim ret As Long
    ret = GetLibInfo(LibName, numEntries, numPoints, hlibComment, FirstX, LastX, DataXtype, DataYtype, bBaseline, libIsAtr, bReadonly, LibBytes)
    
    geInfo = ret
End Function

I am quite sure it is a conversion that is killing me.......Any suggestions/ideas from anyone will do.
