window api FindFirstFile

Declare Function FindFirstFile Lib "kernel32" Alias "FindFirstFileA" (ByVal lpFileName As String, lpFindFileData As WIN32_FIND_DATA) As Long

when we use ora_ffi.register_parameter send variable is only basic type
C_CHAR Means char
C_CHAR_PTR Means char *
C_DOUBLE Means double
C_DOUBLE_PTR Means double *
C_FLOAT Means float
C_FLOAT_PTR Means float *
C_INT Means int
C_INT_PTR Means int *
C_LONG Means long
C_LONG_PTR Means long *
C_SHORT Means short
C_SHORT_PTR Means short *
C_VOID_PTR Means void *

so how to solve the data type like WIN32_FIND_DATA is record type

In this forum, I find many questions talk about send record type in ora_ffi.register_parameter, but no one can provide the correct answer.

I don't.

You have to understand that it is weekend and not many Forum members spend their free time to answer questions.

I am confident that using a type of 'record' is not supported by Forms 6. I don't think it is supported by Forms 9 or 10 either.

Have you looked at using 'd2kwutil'?

From now ,the one method i can think is
1.use other language to complete the request
then make dll file
2.call the dll file in form 6i

Can you do it from the database via a procedure stored there? You would have to pass the components as separate parameters between the Forms and the database procedure.
