Needing some help with excel/vba dll calls. I used the following declare sub and was not sure if the additional records being passed with the BSTR for a string need to be put into the @bytes number? Can someone tell me exactly what bytes number should be specified for this example?
Declare Sub dll_rout Lib "C:dll_rout.dll" _
Alias "_DLL_ROUT@12" (int_arg As Long, ByVal str_in As String, ByVal str_in_len As Long, ByVal str_out As String, ByVal Str_out_len As Long)
Example link below.
