Yes, it sounds like you shouldn't be attempting this task at this stage, you should learn some core stuff first.

You create a combo box, and each item has a value property, set that to the Id of the department whose name it shows. Catch the selected index changed event. Grab that Id, stuff it into a proc that returns the data for that department and databind the returned table to your grid.

Well, for starters, don't use the nasty VB shortcuts, use the proper .NET methods which also work in C#. Otherwise, you're making it impossible to ever use C#, for no good reason.

FileOpen = BAD
File.Open = GOOD

bapu2889 wrote:
Dim LN, LineNo As Integer
For LN = 1 To LineNo

LineNo does not have a value, and therefore defaults to 0. Counting from 1 to 0, involves no iterations of the loop.

bapu2889 wrote:

That's not really true, I'd expect this code to create an empty file. You should set breakpoints in your code and step through to see why things don't work, and you should give more detailed explanations of issues when you post questions, it helps people to help you.

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?

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

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!

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.

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
