I have a binding source that when I use the MoveNext or MovePrevious methods it skips records. I've tried circumventing this by using Position ++ and Position -1 instead but I still get the same result. I even resorted to manually sorting the binding source to see if that would help but no joy as well there.
I have a bindingsource that is tied to a dataset class. I added 2 records to start and movenext worked as it should (moved 1 to 2) as well as move previous. I added a third record and now the movenext method skips record 2 and moves straight to 3. The same symptom also occurred for move previous. I also added a fourth record and it got even weirder. As before when movenext was invoked, the record pointer moved from record 1 to 3. I invoke MoveNext again and it moves to record 4. Now I hit MovePrevious from Record 4 and it moves to record 2 skipping record three.
Others who are working on forms with different bindingsources ties to the same dataset class are seeing similar things.

My problem is when the new data comes out from the API, if it is equal to the previous data and it will appear 0. But what i want is the new data comes out is 0 and it will equal to previous data. e.g: first data comes out is 12.00, in above case, if the second data comes out is 12.00 but it will shows 0 which means unchanged. But in my case now, i want if the first data come out is 12.00, then if the next data is unchanged (0) and it will appear 12.00 and so on.

I have 2 applications that collect data every 5 minutes and imports that data into a SQL Server 2005 table. Every so often the location that I'm quering to get the data hasn't updated thier values so the application is trying to insert duplicate data into the database table. Because I have Primary Keys set on 2 of the 3 columns the insert fails which of course causes an error in my application.What I am needing to do is if it runs into a duplicate insert wait 1 minute or so and then retry running the download data Sub.Each sub calls the next sub in the process line.

View 5 RepliesHow do you restore a dataset to the previous state before updating the database with a data adapter? I have a concurrency update problem that I believe to be caused by this. The update fails during the update and a rollback command is issued using a SQLTransaction object. However, now the rowstates of the rows that did not have errors have been changed to unchanged. So this record is no longer availible to be inserted into the database. When I updated the value that could not be null and then test the second update which runs just as the first does then I get a concurrency error. The update code is below:
