I have a VB 2008 application with multiple DataPicker fields. The data is binded to SQL database. On the form load I set the checkBox for each date to false if there is no date in the field. Noticed that if I make changes to some dates for record 1 in the table, save it and scroll to the next record - I see the date that I just changed for record 1 - also on records 2 and 3. Why is it happening? I don't have that problem if I use text fields to display the dates. I had encountered the same problem with different project and just switched to text boxes. With this new project?

I'm new to Visual basic (which will be obvious from my question) and am writing program that does various calculations, then displays the results in a list box. the results, however, are all concatenated, end don't each appear on a new line. I tried adding a carriage return/line feed at the end buit the compiler rejected it.
I can't find any examples of creating a list box, and adding multiple entries (one for each time a loop is performed), nor of how to use columns to make the resulting display cosmetically pleasing.

I'm using this code to search a msacces db and display the data in a listview.The Search is fired after the text_changed event of a textbox. So each character is a search and also each backspace(here's where the real pain is) it will search. When I use backspace its very very slow! When I use 100 or even a 1000 records no problem but this db has 10.000 + records.Whitch event can I use to solve this problem or how can I adjust the code for faster search? ALs o when I test on a windows7 system, dualcore, 2gb memory, when I press a key it will take time before I see the character in the textboxs? Its a new system and only runs this program.I use a texbox to enter for example an artist name and a combobox where the user can choose to search on artis, title, genre etc. [code]

Running into a situation when user searches for orders of customer for past 4 years. As the DB query takes a long time, I want to show a pop up box just stating 'please wait. quering for results'. so when they start their search I want to show the message box until the results are obtainned and at that point I want to close the message box.My current way, I know is incorrect as the pop up box locks up and states (not responding).Would using a background worker be an over kill, or should I go with a progress bar?
