No VB6 code is going to work in VB.NET, it's a whole new language.
System.IO is the namespace you need.
Directory.GetFiles will get you the files in a directory. Or Folder.GetFiles, one or the other, I forget. Then the FileInfo class is how you get info about a file, such as it's size and last modified date.

The Replace method on the string class can replace the $ with an empty string. Then you can use double.TryParse.

Along with the other suggestions, you could try Double.Parse with the overload that takes a System.Globalization.NumberStyles and choose AllowCurrencySymbol. If you care about working for other currencies than just $, this may be your best bet.

i need to disable ctrl,shift,tab,windows key
is there any coding to disable them and enable them
plz help me

To do this across your whole computer, you need to write a system wide keyboard hook. I doubt VB can do this. To do it in your app, just ignore the keys when pressed.

I think it is possible actually, I saw an article on CP even, yep here it is Click[^]. You'll need to do some modifying but it's all there in the article comments. Just hook Keys.ControlKey etc etc etc and handle them however you want.

You might mention that you are using VB6 - then everyone can ignore your post. There are very few developers using VB6 - it's been a dead language for some years.

That is stupid, it will just get you spam. You will get an email whenever anyone answers your post, anyhow.
Also, as someone else said, VB6 is a dead language, why would you use it ? It was always crap, but it's been unsupported for years.

use string.Replace("'", "''") to fix your strings,or just use stored procs, or parameterised queries, which do this for you.

If you're using SQL Server, use SqlParameter. You won't have problems with special characters and you won't leave open to sql injections. See: SqlParameter[^]

Hi,
i have to validate my password with this rules
1.i can enter any alpha numeric charcter
2.I can enter anything in a valid speical character set
so i write my regular expression like this
[a-zA-Z0-9 + strspecialCharacterString +]
and to avoid special meaning of speical character i am adding \ in front of every special
character.Now my problem in wen i use an _ in my pattern ie some thing like "*_<" it is not
working.It throws an error below
"parsing "[\*\_\<]" - Unrecognized escape sequence \_."
if i give \\ instead of \ it is working.can any body help me in sorting out this problem?
Thanks in advance

Hi,
The underscore character is not a special character inside a regex, so it should NOT be escaped by
a backslash; and when you prefix it by two backslashes, you are actually adding a single backslash
to the list of acceptable characters.

|
|

hi,
Thanks a lot for your my answer.But i have one doubt.Why error is throwing only if we use underscore character."!,@,:" etc are not special character.But if i use them in my pattern no error is throwing. Why is it like this?

These are the characters that have a special meaning in a regex expression:
$ ^ { [ ( | ) * + ? \
If you need one of them literally, then you must escape it with a backslash;
all other characters (including _ ! @ : ) are regular characters, just like a thru z and 0 thru 9.

Please suggest me how can I do this.

I'm not sure there's a way to do that. Why would you want to run a URL invisibly ? your best bet to do that is to put an invisible web control on your form and open the page there.
