thanks a lot

you can try this :
<br />
imports System.IO<br />
imports System.Text<br />
<br />
Dim fr As New StreamReader("C:\\a.txt") 'Create StreamReader object<br />
Dim str As New StringBuilder 'Create StringBuilder object<br />
Dim count As Integer = 0 'Create count for writing line<br />
<br />
While (fr.Peek <> -1) 'Read file<br />
count = count + 1<br />
str = str.AppendLine(count.ToString() + " " + fr.ReadLine()) 'Add string<br />
End While<br />
<br />
fr.Close() 'Close StreamReader<br />
<br />
Dim fw As New StreamWriter("C:\\a.txt") 'Create StreamWrite object<br />
fw.WriteLine(str) 'Write data<br />
fw.Flush() 'Flush data<br />
fw.Close() 'Close stream<br />

That's hardly a description of the problem. Noone is just going to hand over code for you to turn in as your own.
What do you mean by "I need to login / logoff on client PC, through server PC". This doesn't mae any sense. What are you doing with this app?

You mean like remote desktop does ? Have you tried to google the problem ?

 How do I search for a row in a datagrid using an access db in vb.net. I have a textbox and a search button and I want to display the row that I have found by typing in the textbox on a label for each column of the row using SELECT * FROM WHERE
Francois

I may have not understood you correctly, but you may use
Label.Text=TheFoundRow.Fields(i)
for each of the fields of the row if you know how many fields it has.
|
|
|
|
|
I know how to display the current row. You see if you have two fields, an ID And a NAme field, then you will use a loop to get to the id, the problem is how to get to the name field as it is not a number you can loop to. Please help!

You can, in fact, index it by number, or by name.

Hi ALL
I want to design a program that compile a project when i run this program.i mean that i want to buld 2 program but the first program should give some parameters from user and then it build the second one base of that parameters. is here anyone to help me??

In case of writing a compiler, I guess it is much more complicated than to be answered here, and you may read a book on that.
If you had described your problem more clearly, we could possibly provide you with other solutions too.
But personally I guess that what you need is one of my problems long time ago, when I found the best and easiest method to use Microsoft Script Control ActiveX (msscript.ocx) which enables you to run scripts in VBS or JS in your program without any more need of writing a new compiler!
Hope it solves your problem too.

Hi
i think that i should ask my question clearly. i want to code 2 program. one of this programs are the main program that will run and it will be closed 5min after runing without any other thing. but this program need some parameters to be set for first time. and the user should be set this parameters. so i want the second program for setting this parameters. i want to run the second program to get parameters from user and ther buld the first program.
thanks

Why do you need a second program to set parameters for the first ?
The obvious way to run a program with parameters from another program is to pass them on the command line.

Hi
because i want the main program for doing a set of jobs automatically everyday(like backing up, coping some files,executing some batchfiles ...) but there are some parameters that shohld set one time for first time or may be change at sometimes. so i want to set them and put the main program in the scaduled tasks to run everey day. ok?

Still sounds to me like you want a preferences page in your main program, but either way, your app can manipulate settings that the main app accesses, either by being in the same directory, or by using the registry.
Where we've ended up is a long, long way from your original question. You want to have a program which sets up settings which are then read by your main program. You don't want your program to compile anything.

I have an application that pulls customer data from the database and prints a letter using the pulled data. There are times when there can be several thousand letters printed at a time and I am trying to find a way of doing this without sending several thousand single page jobs to the printer. I cannot set up a regular mailmerge as I have to allow the users to upload letter templates with different formatting, content, etc.
I thought that copying each letter into one larger doc, or a series of larger docs, would satisfy. But I am having trouble copying from my original letters into the merged document. I can copy the text using .Selection.SetText(myDoc) but the text seems only to be in plain text format.
This what I have come up with so far. I would really appreciate any advice.
<br />
Dim ofd As New OpenFileDialog<br />
ofd.ShowDialog()<br />
<br />
doc = CommonWordHelper.OpenDocument(wapp, ofd.FileName, False, False, False, False)<br />
newDoc = wapp.Documents.Add()<br />
<br />
<br />
doc.Activate()<br />
CommonWordHelper.InsertTextInBookmark(wapp, "Bookmark", "First insertion")<br />
<br />
doc.Select()<br />
My.Computer.Clipboard.SetText(wapp.Selection.Text)<br />
<br />
newDoc.Activate()<br />
wapp.Selection.PasteAndFormat(Word.WdRecoveryType.wdFormatOriginalFormatting)<br />
wapp.Selection.InsertBreak(Word.WdBreakType.wdPageBreak)<br />
<br />
<br />
doc.Activate()<br />
CommonWordHelper.InsertTextInBookmark(wapp, "Bookmark", "Second insertion")<br />
doc.Select()<br />
My.Computer.Clipboard.SetText(wapp.Selection.Text)<br />
newDoc.Activate()<br />
wapp.Selection.GoTo(Word.WdSectionStart.wdSectionNewPage)<br />
wapp.Selection.Paste()<br />
Thanks
Jim

Basically, you store the key for the department in the value of the combo box, and use that to run the SQL you need to get the data in question.

hi i am doing a tool in which i have to open some ten to twenty telnet sessions in each seperate users will be sigining on and accssing same area and database.using a telnet component i am creating telnet session and giing som inputs and retriving data to gui. for making the process i am using threading.but it takes more time for a single command thats more tha 2 sec which will be taking less tha a second if we open single telnet session could any one tell me the reason pls?
and help me with some advanced threading concepts and sample codes pls
thanks
with regards

Threading does not magically turn your processor into 20 processors. It simply divides a number of tasks to be performed by the one processor. It won't make things faster than if you did them all in the main thread, it's main advantage is in making sure the UI thread remains active so the program does not freeze.

thanks i am also able to understand wat u r saying but my only concern is it should not reduce the speed and make a which will only take less than a second to more or less three seconds
i tried with less no of sessions also means prviously i said i used 10 sec but later i tried with 5 seconds but there is no change in retrival thats why i am getting confused.
will you please send me some links which can give me a better knowledge abt threading for me in vb.net
thanks
with regards

As Mr. Graus pointed out, adding more threads will not speed up a uni-cored machine and has no guarentee of working on more then one core of a multi-cored machine (that's up to the OS).
Adding more threads then cores WILL slow down the machine since each thread's context (the various registers, caches etc) will have to copied to the CPU and then taken from the CPU on each swap. It's called a context switch.
20 threads on 1 core means 20 context switches which adds overhead.
Threads just guarentee that some of your code gets a time-slice and isn't frozen until another thread completes. Such uses are typically for the UI (users hate frozen interfaces) and server apps.
I'm also baffled as to why you're using telnet protocol for data transfers??
Felt the need to post something today 
[sorry, mispelled your name!]
