help for dllcall

[Guest pezz]

my experience in programming is very small, can anybody tell me which data types (or pointers?) I have to take for this function:

function oziConvertLL2Grid(GridNumber:integer;lat,lon:double;var Datum:pchar;var Zone:pchar; var Easting,Northing:double;Lat0,Lon0,Lat1,Lat2,K0,X0,Y0:double):integer;stdcall;

details here: http://64.71.184.220/oziapi/oziapi_docs.html

thanks!

function oziConvertLL2Grid(GridNumber:integer;lat,lon:double;var Datum:pchar;var Zone:pchar; var  Easting,Northing:double;Lat0,Lon0,Lat1,Lat2,K0,X0,Y0:double):integer;stdcall;

according to the help file there is no support for floating point variables. So, sorry you can't use this function, as you will need some "double" values.

there also isnt a BOOL. its just int.

maby you can just use LONG instead of Float ?

(maby DllStruct* commands will also help you)

I found an example in vb, the declaration:

Declare Function oziConvertLL2Grid Lib "oziapi" ( _

ByVal GridNumber As Long _

, ByVal Lat As Double _

, ByVal Lon As Double _

, ByRef Datum As String _

, ByRef zone As String _

, ByRef Easting As Double _

, ByRef Northing As Double _

, ByVal Lat0 As Double _

, ByVal Lon0 As Double _

, ByVal Lat1 As Double _

, ByVal Lat2 As Double _

, ByVal K0 As Double _

, ByVal X0 As Double _

, ByVal Y0 As Double) As Long

Is there really no way to use this function in autoit?

how could I use DllStruct* ?

I'm sorry, the answer is NO, until somebody implements "float" parameters

for DLLCall.

@w0uter: And you can't use "long" in the DLLCall, as "long" is 4 Bytes and "double" is 8 bytes.

how could I use DllStruct* ?

You can't, as the function does not expect a structure.
