try this

dim stringDate as string

stringDate = Format(dateValue,"HH:mm:ss")

--dateValue is the given date
--format function returns string

if you want to have a datevalue then try this:

dim newDate as datetime

newDate = Date.Parse(Format(dateValue,"HH:mm:ss"))

--hope this would help!

yeah, now add .fff to the format string to get fractions of a second.

I m using Visual Studio 2005. How can I drag and Drop Table From Data Connection Node of Server Explorer to Form. I have done it n Visual Studio 2003. But I m not able to do this in 2005. Does VS 2005 does not support it, or ther s a special method for that.

Thanks in Advance

Not sure about whole tables. I drag and drop fields from tables and views with no problem...

hi
i am doing a project in which creating log files for the users signed on . its automated input process so i will be writing each and every input in log file .
log file is a .txt file i am appening the file using streamwriter

at the same time i am trying with another button to read the file using stram reader or any io.files.readalllines() but its not allowing to read. how i can read the file while some strea writes into it. please any one tell me this. i cannot close the stream each and every time as the process is automated for testing purpose.

with regards

What you want to do is impossible. You absolutely need to close the stream, in order to read it.

but my doubt is if you r opening and editing a word document and on the same time if some other user on network trys to read they can open in read only mode and can read lastly saved one then why can us do the same programatically

thanks

Word handles this by creating a temporary file, which is the file that is opened for editing. Read only mode means it reads the entire file, then closes it, it doesn't keep it open.

Open a Word doc, then look in Windows Explorer, you'll see the temporary file there.

Hi,

I beg to differ: whoever creates/opens a file is in control regarding the
operations others can do to the same file.

one can easily share a file between threads and even processes; it suffices
to apply the correct FileShare value when creating/opening the file.

My example shows a first stream writing to a file it allows others to read,
and a second stream reading from same file allowing others everything:

string filename="streamTest.txt";
using(FileStream fw=new FileStream(filename, FileMode.Create,
		FileAccess.Write, FileShare.Read)) {
	using(StreamWriter tw=new StreamWriter(fw)) {
		tw.WriteLine("Created new file");
		using(FileStream fr=new FileStream(filename, FileMode.Open,
				FileAccess.Read, FileShare.ReadWrite)) {
			using(StreamReader tr=new StreamReader(fr)) {
				for(int i=0; i<10; i++) {
					tw.WriteLine("line "+i);
					tw.Flush();
					string s=tr.ReadLine();
					Console.WriteLine(s);
				}
			}
		}
	}
}

BTW the flush is there to undo the buffering that takes place in these streams;
without it there probably would be nothing to read when the short loop
terminates; for longer streams, flushing is not needed ! And normally
the reader should continue to read after the writer has done, my example does not.

Smile | :)

PS: sorry for posting a C# example in a VB.NET forum !

please be more specific: if it throws an exception show it; if it runs but
does not produce the expected outcome, please explain.

I did run my example before posting it. Much depends on the FileMode, FileAccess
and FileShare values you use EVERY time the file or filestream gets created/opened.

e.g. the simplest overloads for creatinbg/opening a file (those with default values
for FileShare) would use FileShare.None, disallowing others to touch the file.

I am developing ASP.NET Web Application using vb.net One of
the requriement of this application is ...when user submit

Does anybody knows...How to Open and Writes into Word

What on earth are you thinking here ?

1 - I told you that ASP.NET isn't going to matter to your solution
2 - I told you what you need in order to do this, all you have to do is google and download it, I'm sure it comes with samples
3 - for all that, I am sure that you're not the first person who wants to do this, there must be countless google hits that will tell you the answer, with code
4 - posting the same question over and over, when the last time you asked is still visible, is just plain annoying, it's not going to leave anyone inclined to answer you any faster.

OK, well, perhaps you need to write a single, intelligent post that actually outlines what you have done, instead of posting the same vague question over and over ? If what you want to do, occurs on the client side, then it's not going to work in ASP.NET, because the server code is on the server, not on the client.
