This is the article which i found on cp about serial communication. I know it is quite simple if i am communicating between 2 computers but what if i am communicating with a hardware instead of computer? I have been told that it is the same between communication with computer or hardware but i just dun quite understand the concept. Current i have part of the code in my server pc and the other part i do not know how to apply. I dun seem to be able to open the port and send command to my hardware. Have anyone done a similar project and please advise me what to do?

You've been told before. There is NO DIFFERENCE between talking to another computer and talking to a hardware device when communicating over a serial port.
If you know how it works talking to another computer, the EXACT same concepts apply when talking to hardware.

Then it would appear that you don't have the communication paraters correct, like baud rate, stop bits, parity, handshaking, ...

Yes..,
There is no difference between taking to another computer and taking to a hardware device.
Checkout the settings(buadrate,parity,flow control....) of your hardware device, is responding..., then only u can get correct response for your command...

So...why are you telling me this and not the OP?  I already know how it works.

I did already done the confirmation of the setting but still no reaction from my hardware. As i saw in the article i found on cp, there is another set of code suppose to be at the other pc so i wonder where should tis set of code be at if it is for hardware. Cant possibly put the code in a hardware.

The other "set of code" on the other PC is there so there's something that listens to it's serial port and can respond to requests comming from it. This is already built into the device you're trying to talk to! Seriously, how long have you been using computers??

Sorry for being so noob. Thanks anyway i got my command line to my hardware already. But the question now is i was unable to see the reply. How can i get the reply to be posted at a list box? Which means i need to display the reply from the port to list box.

SH*T man, When are you going to stop? You need a messenger, then you need this, then you ask for books, then you come back to this.
NO ONE IS GOING TO GIVE YOU CODE

STOP bothering us for an entire project just because you are either too lazy, too stupid or some combination of the two to do your own work.
NO ONE HERE IS GOING TO GIVE YOU AN ENTIRE PROJECT.
Have you not figure this out yet?
Apparently not since you keep posting idiot questions like this.
CONGRATS! You are a complete idiot! There's you f***ing code.

The worst part is how many notepad vb6 clones exist, with full source included that this guy can't f***ing use google.
Honestly. GOOGLE, it would have given him this and his stupid messenger already.

Some advice :-
1) Do not be developing in VB6, it's a dead/dying language.
2) If you can write a simple Notepad program, then maybe you should consider a different career.

Dont use such language. I work in VB6. 
The word "politics" describes the process so well: "Poli" in Latin meaning "many" and "tics" meaning "bloodsucking creatures."

Sorry to say that VB6 has not been supported by MS for quite some time now.
Oh, and the runtime is not supported under Windows 7.

You're a student of "Computer Software Engineering" and you can't figure out how to write a Notepad application?? If this is giving you a problem, perhaps you've picked the wrong career path.
And stop asking for complete projects. Noone is ever just going to hand over their hard work to you.

No way! I still see everything in shades of green from the last time I looked at it. Now I need to wear protective eyewear all the time.

Yikes!
Computer Science student and he's using VB6 for a notepad app? WTF?

I have 2 ranges, I want to create the third range based off range2-range1.
I tried pretty much that, and have contemplated suicide for about 15 minutes.
Any ideas?

How? Can you post what you did? Should be possible, AFAIK...

I think I have to use excel.Evaluate, I'm just not sure how.
I have a predefined range in one of my worksheets and I set it to a variable as Excel.Range, called Weeks.
Then I use
'the range of our unedited weeks from the node
Dim UnEditedWeeks As Excel.Range
Dim AddressLocation As String
'address of our range, topmost left bottommost right
AddressLocation = "C" & CStr(StartRowCount) & ":" & "AO" & CStr(EndRowCount)
'should be our range
Set UnEditedWeeks = Worksheets(CStr(NodeSheet)).Range(AddressLocation)
To get a new range of seperate values, this works I've stepped through it.
Now I just want to create a new range of the difference of these two ranges.

IIRC, this should be
Set UnEditedWeeks = Worksheets(NodeSheet).Range(AddressLocation)<br />
The parameter is either the Worksheet name (as a string) or a number (starting with 1). Since you are using CStr, I presume NodeSheet is a numeric variable. If, for example, NodeSheet is 2, Unless you have a sheet named "2" in the workbook, this will give an error.
Also, from your code, I do not get an idea of what error you get, and how you tried to

No the sheetnames are strings, so it has to be converted to a string. I don't get an error over there.
Think of it as matrices, for example
Range 1
2 4 3
1 3 1
5 2 1
and Range 2
1 4 3
2 2 2
5 2 1
I want to create Range 3 in memory with the contents of Range 1 - Range 2 so my Range 3 would be
1 0 0
-1 -1 1
0 0 0
