So the listview is a shared variable ?

Yes. Listview is a shared control drawn on frmMain.

Wow - that's a bit of VB nastiness I didn't know about. So, what happens if you have more than one instance of the frmMain class ?
Anyhow, VB sucks. You want to create a delegate so you can call it in your second form, and it calls a method in the first form, passing through the data.

There is only a single instance of frmMain class.
Yes I want to use a delegate to show searched files on the listview of frmMain.

Yes, but I just did a test and found that while in C#, I'd tell anyone who made their form controls static that that is a TERRIBLE design, it seems in VB it does that for you. And, given that VB is doing it, what happens if I have more than one instance of a form ? It's insane. VB sucks.
OK, well, have you read up on delegates ? I'll be honest, I know a delegate is what you need, and I'd expect any basic tutorial on delegates in VB to give you the code you need, but I use C# ( did you notice I hate VB ? ) and so I can't tell you off hand what the syntax is.

Is someone seriously going to read through 9000 pages of a print preview ? Either this is a limitation of the control, OR it's a problem with your code.

thank u sir

I think you may be the only person I've ever heard of that wants to preview 9,000 pages.
Seriously, I don't see why it would be a limitation in the control, but, it's entirely possible. Other than that, without any kind of error message or how you're handling printing, noone can tell you anything useful.

Maybe its a better idea to produce one big pdf file (or a lot of smaller ones ...)

Ah. you can get a handle to the program in question when you call Process.Start and you can make your program wait until the other program finishes, or you can check it to see if it's still running.

Hi,
Read about the System.Diagnostics.Process class on MSDN and pay special attention to the example associated with the Exited event. It summarises the basic code that you will need to implement to detect when a process terminates.

I want to combine parameters and fixed values in queries as this strQuery = "insert into books (zaglavie, avtor_id, book_id, book_udk, janr_id) values(?,autor,?,book,?)" where autor and book is global variable

It doesn't matter where the variables come from, you can still pass them into a paramaterised query. Or do string mashing if you don't care about security.

Hi,
I have a datagridview1 column "Name", which has collections of names and some are repetitive; e.g.
"Name"
-------
ram
shyam
ram
ram
raj
shuk
shuk
So, in the above "Name" column, there are repeatation of names. I want to do this:
1) read the repetitive name as a single, e.g. "ram", "shuk"
2) store them in a array of string;
3) finally the array should be like this : arr(1) = "ram", arr(2) = "shyam", arr(3)="raj",arr(4)="shuk" .
So in arrays I have finally stored the repetitive names as once.
Now I want to copy these array entries into rows of another datagridview2 whose column name is "Final Name".
Can someone help me by providing a piece of code?
Thanks
R.S.

No I have not executed any transact sql statement.
My code is like this :
cmd = New SqlCommand("Select * FROM student_details", con)
If con.State = ConnectionState.Closed Then con.Open()
myDA = New SqlDataAdapter(cmd)
Dim myDataFillSet As New DataSet()
myDA.Fill(myDataFillSet, "student_details")

I think you are using... whatever .. update the SQL statement by using SQL JOIN.

You ARE using a query to get the original data, just run another query to get The DISTINCT name values.
SELECT DISTINCT(StudentName) FROM Student_Details ...
