Hi,
I created application that I get information from AS400 for reporting.
In main.exe has only 1 frm which calls (as a class library) CLS_MAIN.dll.
The CLS_MAIN.dll get the tables from AS400 and stores it in Dataset.
Then returns to main frm then main frm calls the FirstReport.dll .
The FirstReport.dll get the information from access database and creates the
sqkl string and works with dataset and then writes in pre-formated Excel
sheet.
I create main_thread in main form(frm) that calls for CLS_MAIN(dll), then
FirstReport(dll ) and WriteInEXCELL(d ll).
Now while is doing this I createted cancel button. Main purpose of this that
user can be able to cancel creating first report and can goto second report.
But I cannot be able to stoping the thread. When I use serverThread.Ab ort()
it goes to main form and when user try to create second Report gets exepction
that Thread did not stoped or cannot create same thread again.
I want to cancel the thread then user can send different parameter so she or
he can be able to create different report.
I learn that I should use the serverThread.Jo in() after the calling the
serverThread.Ab ort(). But I don't know how to applie to my application.
I also like to know how to unload the class(dll's).
I thank you in advance to helping me out.

Niyazi,
Not 100% sure I got your question...
Here are my 2 swiss cents:
When calling thread.abort, this will raise an abortException in the thread.
It is up to you to catch it so as to perform clean up.
If I recall correctly, you cannot reuse your instance of the thread that was
previouly aborted. You have to get a fresh one and call the start method.

Hi Jose,
Thank you for info.
When I catch the exeption then what should I do, without killing main.exe?
The thread reside in main.exe. Also how to create fresh thread?
In frmMain I use this code:
'PRIVATE MEMBERS
'Server Thread
Private serverThread As New Thread(AddressO f _MAIN_THREAD)
When user clicks the button does some userinterface changes and then call the
Private Sub playAnime() that shows Macromedia Flash loading, creating anime
and then calls the tread as:
If Panel1.Visible = True Then
serverThread.St art()
End If
and then in _MAIN_THREAD I have this:
'MAIN THREAD

Thread creates a report maximum 7 min and min 1.30 min.
But if user clicks cancel button I need to kill the thread but not the
main.exe
So user can get different report.
Here is the Cancel button code:
Try
'Stop the SERVER_THREAD
serverThread.Ab ort()
If clsConst.checke dBox = "BL100A" Then
chkBL100A.Enabl ed = True
'Show the check mark graphic
pBox1.Visible = False
AxShockwaveFlas h1.Stop()
Panel1.Visible = False
ElseIf clsConst.checke dBox = "KZ100A" Then
chkKZ100A.Enabl ed = True
'Show the check mark graphic
pBox2.Visible = False
AxShockwaveFlas h1.Stop()
Panel1.Visible = False
End if
btnENTER.Enable d = True
Catch ex As Exception
MsgBox(ex.Messa ge)
Finally
serverThread.Jo in()
End Try
As you can see I create the New instance of the Main thread but after I
cancel and try to get other report I get an error. I know when I abort the
thread I have to wait a certain time to thread will be realy dead. So I
should warn the user while the threat aborting that "Wait! Canceling the
......Report".
But having hard time to to code this. Also if I catch the exception How to
perform the clean up.
I realy appriciate your info, and I hope you can help me bit more.

Hi,
I like to use thread to simplify the handling of independant,
blocking tasks. But controling them from a main thread is
not always easy to do in a clean way. So I've written some
generic code whose purpose is to start and stop threads in
a synchronous (blocking) way from the caller's point of view.
Hence, after start() is called you are garanteed that the
thread is running, and after stop() you know it has completed

I use a Synclock in a secondary thread and also stop the thread using the
abort method.
If the abort occurs while the thread is in the Synclock will the SyncLock
always be released before the thread stops or do I need to add some extra
