Not even close. That has nothing to do with printing at all. It's controlling individual pins on the parallel port.

Your correct. Sorry it was a long day and for some reason LPT1 was in my head and not printing. I was looking for a way to open and write raw data to parallel port.
Now that I have had a good night sleep, it seems like there is a way to write raw data to printer using the System.Drawing.Printing namespace. If I get time I'll dig out one of my old projects, I think I actually have done raw mode to printer, although it may have been over TCP/IP not parallel port???

You could try my Code Snippet Manager[^], I'm sure it could be adapted to VB.NET without too much difficulty.

What "don't work"? If you wish for help with your problems then it's about time you made a greater effort to explain them in proper technical detail.

Maybe if you bothered to read the article you would find out how it worked and how it might be able to help you. You really need to make a bit more of an effort for yourself and not expect to be spoon fed for the rest of your life.

Great link. Thanks Richard.

how to type in a datagridview textbox column and find in a listbox like a tally finds in vb.net

Not everyone is aware of what Tally is or how it works. Please be specific in what you are trying to achieve and where are you stuck.

My ticketing system has reached a point where the installations will need to communicate with the office. I cannot guarantee constant connectivity.
I am thinking of SOAP with Web Services. It appears easier to follow than TCP networking and in my limited knowledge perhaps better suits my needs.
Traffic will not be constant and it will function more as a notification device telling the office what transactions have taken place onboard, and the office will then notify other installations of tickets sold elsewhere.
What should I be looking out for?

Hello 
I have a class :
cls_Communication_base
which has a private variable
Private p_Descr as String = nothing
and a public property
public Overrides property [Descr]() as String
get
return me.p_Descr
end get
set (ByVal value As String)
me.p_Descr = value
end set
end property
I have some load method, which loads data
from a data table and assigns the value from
the datarow to the property
row is a datarow from a datatable with 47000 Records
public overrides sub fillDataRow(byval row as system.data.datarow,byval bolBuffer as boolean)
...
If (Not row.isNull(5)) Then
' this line is too slow, really!!!!!!!!!!
me.Descr = row(5).tostring()
End If
....
end sub
Like said. Everything is ok in terms of speed. Only the line assigning the row value to the string property is really slow.
OK. I am skipping a lot of lines here to make the example easy. But, Without this line assigning the value to the property (but creating 47000 instances of my class and doing everything like querying the database takes Zero Seconds). Just including this one line and the whole thing needs 72 seconds
So, I guess there is something wrong in my way assigning strings to a property
Is there a better way assigning values to a string property?
Many thanks for helping

Not sure that there's any other way let alone a better one!
