How very javascriptish--
anyway, check your Form.designer.cs file for BtnOk.Click+=new EventHandler(object sender, Eventargs e);
and then check your Form.cs file for the same. Get rid of one.
If you want to register that EventHandler always, leave it in the designer file, if you want to attach it if some condition is met - take it out and do it in the form.
var question = (_2b || !(_2b));

Its quite simple...add another button in a new project, put breakpoint and check is it calling twice or not. If it is then something wrong with your windows or your mouse is dying.

Dear Friends,
I have small application in C#. to insert some record in a table. I am using select max(primary key) from tablenme to get the max id and insert the record with other information.
If single person work it is running properly. But if 4-5 peoples run the same application and they try to save the record some time it gives error as "ora 00001 unique constraint (constraint name) violated"
Your quick response will be highly appriciated
Regards
Murtuza

How long between selecting the max key and inserting the new one?

I don't remember the Oracle syntax for it, but the major RDBMSes usually an auto-increment or identity field of some sort. If you use that for the ID, the database will automatically generate a new value when the record is inserted.
Failing that, a few alternatives:
1) Put it all in one DB transaction using a temporary variable. That means get the next index and insert the new record as one combined operation, so nothing can happen in between.
OR
2) Create a stored procedure on the database that inserts the record and returns the ID (If you need to know the ID). Again, keep the entire operation on the database side.
OR
3) If you must do it all on the client side, catch the exception, wait a random number of seconds or milliseconds, and repeat the operation (Checking for the next ID again). This solution is less than optimal, but it's commonly used in certain network protocols.

If you're using Oracle, look at harnessing the power of a Sequence. This will give you a value that you can use for your primary keys.
Usually you have one sequence per table that needs a numeric primary key.

I am using a rowfilter with a dataview. How can I ascertain the number of rows which are being displayed please?
|
|
|
|
|
You can use
dataview's rowfilter property="select top 10 "
This might work fine
Thank You

I used DisplayedRowCount() to do the job.
Many thanks to those who took time to offer suggestions - much appreciated.

Yogesh, this is third post of yours.... and you are still not clear what you need...
as Colin posted, which operation you need after the drag and drop....
if it is copying files( i assume this - Copping)
then have a look at this article....
Drag and drop, cut/copy and paste files with Windows Explorer
Have a Happy Coding.....

1. Stop calling everyone sir, we are not a bunch of knights here you know
2. Stop posting the same friggin question every 5 minutes
[EDIT]
2 1/2. Why are you even posting when you clearly are not taking anyones advice anyway?
3. Finally, and most importantly, QUIT TRYING TO BE A PROGRAMMER BECAUSE YOU CLEARLY ARE NOT CUT OUT FOR A LIFE OF USING YOUR OWN BRAIN TO SOLVE A PROBLEM WHICH IS WHAT BEING A PROGRAMMER IS ALL ABOUT!!!!!!!!!!!! (12 should do it, now to bold or not to bold...)
4. Why have you not quit yet?!?!?

Wait a moment! This forum post was part of a technical test in a job interview!?! Isn't that cheating?

That's not the idea. This site is here to help people, including you. Reposting the same question repeatedly isn't going to get you the help you seek though. Neither is not following the advice you've been given and not explaining why.
If the advice given was incorrect, then you should post back to the same thread with an explanation of why it didn't help. If it was a problem with the way you expressed the problem, edit the post and the subject will change to modified so others can see it's changed and will reread the question.
