Can some explain plz. Basic uses a C++ wrapper.

[Intermouse]

I have recently purchased an aspi wrapper control for vb.

I haven't had much experience with hex and memory addresses and that's my
problem.

The piece of code that baffles me is:

With ASPI1
.HostAdapter = 0
.SCSIID = 4
.CDBSize = 10 'LINE 1
.CDB = Chr$(&H5A) & Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) &
Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) 'LINE 2
.Execute

End With

Print "SENSE BUFFER: " & ASPI1.SenseBuffer

The first line sends a command of 10 bytes I know. What is CHR$ doing. I
know that it returns the ascii char for the character, but how does that fit
in with the command descriptor block. How does the translation work.

The second line specifies the length of the command that is going to be
sent. I know that.

Anyhow i have pasted the scsi2 spec for a 10 byte command here:

http://www.intermouse.net/aspimodeselect10.htm
for reference.

So,

I need to figure out how to translate the scsi2 commands into the wrapper
function. Line 1.

If anyone knows what I am rambling about, I would very much appreciate some
help.

Mucho thanko.

Your question hasn't anything to do with C, as far as I see...

 

[Intermouse]

The ocx was written in C++.

The ocx was written in C++.

1. Don't top-post.
2. Don't forget to post to an assembly group because part
of the Windows operating system was written in assembly.
3. Just to be safe, you may want to also post to the Pascal
and C newsgroups just to cover all bases.

When you have an issue involving the syntax or semantics
of a language, post to a language newsgroup. When you
have issues with an operating system or platform, post
to a platform specific newsgroup.

[please don't top-post]

The ocx was written in C++.

"OCX" means it uses a language-neutral binary interface. No C++ visible.

The ocx was written in C++.

Minesweeper was written in C++. Should I post minesweeper questions here?

While you may not care for top-posting, others such as myself find it much
easier to read.

Wow.

It seems that some people spend their time replying to posts just to tell
others that they posted the message wrong or in the wrong place. Are we all
message group mediators, or are we really trying to help each other?

Top post, side post, over the post, who cares as long as the message reaches
the far corners of the earth and hopefully gets some REAL answers.

Thanks for all of your much appreciated......err.........postings!!!

As for comp.lang.c++:
You are free to leave if the rules of the group are unacceptable to you.

 

[Norm Cook]

Concur. I hate having to scroll to the bottom of every message to see what may or may not be some profound response.

Then _trim_ the junk. Just keep enough to maintain sequence and context.

See?

See what happens when stuff is cross-posted to a BASIC newsgroup?
Nothing good.

Bloody left posters...

As for the OP's question and hopefully to end this silly thread.

With ASPI1
.HostAdapter = 0
.SCSIID = 4
.CDBSize = 10 'LINE 1
.CDB = Chr$(&H5A) & Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) &
Chr$(0) &
Chr$(0) & Chr$(0) & Chr$(0) & Chr$(0) 'LINE 2
.Execute

ASPI1 is a class, object whatever..
That first line simply sets the number of characters that it will
send, just as the previous lines set the adapter number and the ID to
send it to/with.
Chr$() gives you an ASCII character, .CDB = chr$(x) & chr$(x) and so
on, simply builds a byte array or string(call it what you like) with
the characters added on one by one.
So if you send chr$(65) & chr$(66) & chr$(67), then your output would
be "ABC". Which would be identical if you had done .CBD = "ABC".

Clear ?
