Heh. Well, what I meant by cheap-o knock-off isn't the price-tag (or lack thereof) it was more based on something I read during my search for code that it was just repackaged rehashed stuff. That was after I attempted to wade through the techno-jargon without getting lost. As for the books---I live in a rural part of Virginia, about 75 miles from bookstores that don't really carry anything besides how to grow tobacco and creating your first moonshine operation. Hence the appeal of just trying to find code on teh trusty intrawebz and typing it in myself, and seeing if that didn't shake a rusty bolt or two loose in the old noggin'. But failing this---there might be a way to persuade the local book-store to order something. He'll probably just see dollar signs the moment I mention "special order". Thank you all for your friendly tips and suggestions.

if you can't make it to a decent book store, there is always a virtual one. Try Amazon, it doesn't browse well, but it sure offers a wide choice of great books.
You are aware CodeProject hosts over 20,000 articles, and a reasonable fraction of those are interesting and good?

You should also try to google for free vb.net books. There are a surprising amount of free (and perfectly legal) books that you can download, especially for beginners.
Another way to get you started, is to type "walkthrough" in the help/search section of your visual studio. It will provide a lot of step-by-step instructions on how to do all kinds of different things, and will give you some example code that you can copy and paste. That will give you something to start with, analyze and build upon.
My advice is free, and you may get what you paid for.

How to enable/disable network adapter in WinXP and Vista with VB.net code

Without a damn good explanation to why you want to do this nobody will help you with this.
And even then it's very likely they won't.
Why? Because you should NEVER disable hardware on a pc. That's called a virus / malware and nobody here will help you with that.

I have friends that use NET in PPPoE protocol and sometimes they disable theire network adapter and call me with answer how to enable their network adapter. I understand how to enable and disable network adapter, I use devcon.exe download from here http://support.microsoft.com/kb/311272[^]
Thanks

No way is anyone going to do that. You can buy converteres, or you can put the code in a dll and just use it from there.

umm it should be pretty straight forward ....
just remember in C#
dim MyString as String = ""
=
string MyString = ""; <-- Dont Forget The ';'
if (...) then
...
else
...
end if
=
if (...){
...
}else{
...}
and so on ... any .NET programmer worth his salt should be able to do this.
If at first you don't succeed ... post it on The Code Project and Pray.

OK, this are bad news for me...
Does someone know a similar project in VB?
Last but not least: thankyou for your help.

Get .NET Reflector here: http://www.red-gate.com/products/reflector/[^]
Get file disassembler plugin for Reflector here: http://www.denisbauer.com/NETTools/FileDisassembler.aspx[^]
Then just disassemble compiled project into VB.
You'll get messy list of files but it will compile and will work, and you'll probably get what you need.
However - my main comment is - don't stuck on one language! Learn VB.NET and C#.
P.S. If you're asking someone to do your job every time - this means that you'll never get your own brains working.

Hello Every One
I am having one listview in that i am adding one column like
me.listview1.column.add("Rupees,50,Horizontal.centre")
now i fetch records from database in it
for filling listview and it worked
but the problem is i want to add the Rupees of listview and display it in one label
For that my code is like:
dim i as string
dim n as integer
dim t as integer =me.listview1.count
for i = to t-1
n=i+me.listview1.selecteditem(0).subitem(1).text
me.label1.text=n
but this seems to be wrong code can u please suggest
some another...
i am beginner
Please help...

1) you have ' dim i as string ' but are using 'i' in the for next loop. change to 'as integer'
2) is your intention to add up all the selected items? if so, you aren't doing that. you are adding the same value of the first selected item for as many rows that there are total.
3) The for next loop is declared as 'to listview1.count - 1' inorder to add up all the selecteditems, you need to change that to 'to listview1.selecteditems.count - 1'.
4) where's the word 'next' at the end of the loop
Dim Tot as integer = 0
For i as integer = 0 to listview1.selecteditems.count -1
Tot += cint(me.listview1.selecteditems(i).subitem(1).text)
Next
me.label1.text = Tot
Hope this helps...

hello
Dim Tot as integer = 0
For i as integer = 0 to listview1.selecteditems.count -1
Tot += cint(me.listview1.selecteditems(i).subitem(1).text)
Next
me.label1.text = Tot
The code u suggested just gives me the one by one value of items present in listview
eg :i placed this code on listview double click event so it just give me value 1 when i double click on selected row and then 2 and goes on.
but i want the total of the items present in row and display it in label
for eg:suppose there are two listviews both are having columns as Rupees but the first one is having Rs in it like(100,200,300 etc..)
what i want is when i double click on any of row of first listview it adds the items preset in the selected row one by one and displays it in label
like (100+200+300) which gives result as 600 in label
simply saying i want total of text present in the listview
so please suggest if some have any idea.
Thank You.

I am trying to import csv files that have comma embedded within quotes. After trying to figure the regex pattern I ended up nowhere. Using Jet drivers is the last option I could go for. Could anyone provide some help on how to do this kind of importing.
Thanks in Advance.

This might help - it's taken from Mastering Regular Expressions (2nd ed.) by Jeff Friedl (O'Reilly, 2002).
You need to use the RegexOptions.IgnorePatterWhitespace or edit it to leave only the RE bits.
dim regStr a s String = _
"\G(?:^|,) " & _
"(?: " & _
" (?# Either a double-quoted field... ) " & _
" "" (?# field's opening quote ) " & _
" (?<QuotedField> (?> [^""]+ | """" )* ) " & _
" "" (?# field's closing quote ) " & _
" (?# ...or... ) " & _
" | " & _
" (?# ...some non-quote/non-comma text... ) " & _
" (?<UnquotedField> [^"",]* ) " & _
" )"
Oh and check for matching parentheses - I think I've got them right but...
Regards
David R

Hi,
without any more information about your app and the inputs you provide, here goes my wild guess of the day:
the most popular way of getting such exception is by parsing the content of an empty textbox; left empty those bastards tend to be just unparsable.
the second most popular cause would probably be a mismatch between your regional settings, the user provided data and your code.

Hi,
I’m following a tutorial using serialization/saving records.
I can make records, display them ok in a datgridview and then save them ok using serialization. Then I can reopen the programme and reload the dataset from the deserialised file, and show the records ok in the datagrid view - but I cannot add any more records to the datagridview.
I’d be grateful for any help/advice/assistance.
Regards,
Steve
