Answer 1

Hi Jessica,

Why you declare this different:

Dim SNR As Double          
    Dim BER As Single

?

Have a nice day.

Answer 2

Some of the types aren't correct (note that "BOOL" in C++ is not a boolean, but an integer) - use:

Public Lock As Integer
...
Public BitRate As UInteger
...
Public BER As Double

Answer 3

Hi,

May it be this?

You have defined a structure pointer in the function: PSEARCH_RESULT, it points to a stucture, not an array. Please try it.

Best regards,

Answer 4

Hi,

look at this:

BOOL (WINAPIV* BLScan2)(DWORD freq_start, DWORD freq_stop, DWORD pol, DWORD lof1, DWORD lof2, DWORD lofsw, PSEARCH_RESULT pSearchResult, PDWORD pTpNum, BLSCANCALLBACK lpFunc) = NULL;

Do you find "PSEARCH_RESULT"?

Based on the typedef, it is a pointer, a pointer pointed to a structure, but you passed a stucuture array in this function.

I clear?

Have a nice day.

Although it is a C# code sample, but I believe you can learn what you want.

Have a nice day.
