Is SHORT an undocumented param type?
Vlad
>Instead of BYTE you can use SHORT, at least for me this works most of the time. Some calling convetions expand parameters to 32-bit values anyway. A BYTE ByRef is a STRING@ where the string is CHR(x). Please note that SHORT@ doesn't work in VFP 5.

>The Type definition, a structure, can be resolved in VFP using my struct class (STRUCT.ZIP here in the library). With that class, the VB structure looks like this in VFP:
>
>DEFINE CLASS LStatus AS STRUCT
> DStatus = 0
> DCode = 0
> PStstatus = 0
> cMembers = "l:DStatus,l:DCode,b:PStatus"
>ENDDEFINE

>>Hi I need to convert some VB Call to An API Function into VFP, The VB Call IS:
>>
>>Public Type LStatus
>> DStatus As Integer
>> DCode As Integer
>> PStatus As Byte
>>End Type
>>
>>Private Declare Function GETStatus Lib "SomeDLL.dll" ( _
>> ByVal device As Integer, ByRef status As LStatus, _
>> ByRef devStatus As Byte, ByVal mode As Byte) As Byte
>>
>>My biggest problems are the Variables type BYTE, how do they convert to VFP and also the Structure LSTATUS
>>
>>My Conversion is the following:
>>
>>DECLARE INTEGER GetStatus IN SOMEDLL ;
>> INTEGER nDevice , STRING @STATUS, ;
>> INTEGER @devStatus, INTEGER mode
>>
>>It does not work properly and dont return anything in the Status Variable, The VB Call works fine.

>>Anyone help will be greatly appriciated.
