I am creating an application in vb.net in which many users can add, update, and modify data stored in sql, but one user at a time. Users have to login to the application and then they can start their work. I want to know how I can monitor their work after they log out, like which user updated the record and at which time.

View 1 RepliesOn my website I have user records. For the user records page I have three options you can do with each user record. Delete, Update and Email are my checkboxs's that I am trying to use.
<Input Type=CheckBox Name=Delete OnClick="False" Value=<=rs("num")%>><br>
<Input Type=CheckBox Name=Update OnClick="False" Value=<%=rs("num")%>><br>
<Input Type=CheckBox Name=Email OnClick="False" Value=<%=rs("num")%>>
What I want to be able to do with these check box's is when one of these slections are made, I want to be able to pass the value of the selected checkbox by pressing a button over to another page where I have a IF statement. Then value of the selected checkbox runs though the IF statement and matchs with the option in the IF statement.
[Code]...
So I guess what I am looking for is how do I get the value of the checkbox to pass over to another page and run through my IF to match with an option in my IF statement.

I've got a dual monitor setup, my main monitor is a Dell 20" 1680x1050 res, secondary is a Dell 17" 1280x1024.I've just updated my gfx driver (nvidia driver version 190.62).I'm using code like that shown below to get the screens and I always assumed that AllScreens(0) would be the primary screen and AllScreens(1) would be the secondary but this appears to be reversed since I updated my driver.

Is my coding in error or is Windows reporting the screen information wrongly ? How can I be sure to set AllScreen(0) as the users primary screen and AllScreens(1) as their secondary ?

View 4 RepliesI have a program that records time data in database when the user performs task. When I published the program for user install, I did not specify any update location. So, since initial creation, whenever I need to update the software, I simply install the new .exe file and this overwrites the old version and erases all data created by the old version (similar to uninstall and reinstall). Is there a way to only install updates to the software so that all data is not erased each time I need to update? Seems like this would be simple, but I can't figure out how to do it and am quite new to programming. I will eventually want to have the software check for updates online, but I need to understand how to update from a local file location first (without erasing current data).
View 3 RepliesI have this program im making it is supposed to be a basketball game monitor. The user enters two teams and the 12 players on each team then it has you pick the 5 active players and takes you to the run form where you can start the game once started you can add things like fouls and baskets made and attempted if a player gets 5 fouls or you hit stop clock you change which players are active and its supposed to update the database through the dataset and dataadapter but it doesnt seem to update the database with the info put in the datagrid view.

View 1 RepliesI want to launch a bunch of threads, each performing the same task, and know in main() when each finishs and it if it was successful or failed.The solution offered was to use a ConcurrentQueue, but other posts have recommended using a BackgroundWorker Class, or a thread pool.Is there a definitive answer?Again, all threads perform the same code and have a pass/fail result. I want to run more than there are available threads so as soon as one thread finishes I will launch another asap - I want tehm to stress a remote systems as much as possible (reather than stressing my local PC with too many threads, so I will need to experiment to determine the optimal number of threads).
