I need to update my db every 5 minutes but don't want it to effect how my web application is working (should work behind the screens).
I currently do a web services call from a button to do the manual update of the db but want this to happen automatically.
What is the best way to do this in asp.net in php the equivalent would be a cron job.
Can I have a class that makes this call in the background?

I have Requirement to update the label text as we are processing the code (Long running).
Example:
I have Label and button on aspx page.
On button Click Iam calling the AppCode which is going to do long work for me.
I want to update the label text from the appcode (which should reflect in the page then and there.)
I have tryed to pass the text value to the label but it shows the changed text only after the event for the button click is finished.
I tryed using timer but as soon as i click the button the refreshing stops.
I tryed progress template and UpdateProgress without success. (I know we can update at the start and end of proccess using this)
I dont want to use iframe (I know we can do using iframe)
Lets say i have a button control on a page and a label control. On clicking this button it performs series of actions say Action 1 , Action 2. Action 20 which will take say approx 1 hour to complete. What i need is, once this long processing is started, My web page should show the status of each action on label. Eg. After clicking a button, Label1 text should be "Action 1 is started" after Action1 is completed and Action 2 is started ,.... Label1 text should be "Action 1 Done...Action 2 started" I need this so that my user can see whats the current state of processing.
View 7 RepliesI have a web form for a user to update their user information. I have an ObjectDataSource configured to use the Update method in my BLL. If the user changes their email address in the web form, the BLL Update code checks to make sure the email address is not already in use. If it is in use, I want to cancel the update and notify the user.I was going to raise an ApplicationException in the BLL and catch it in the web form code-behind, then present a message to the user. But from what I read, this is bad practice: http://blogs.msdn.com/b/kcwalina/archive/2005/03/16/396787.aspx

I have a .net 3.5 application in c# with sql server 2008 at back end. The application is about assigning jobs to supervisors and then these supervisors have to write remarks about the job progress from time to time. There are two tables ; a JobAssign table with JobOrderNo and Supervisor columns, and a JobUpdate table with jobOrderNo,Date And Remarks(nvarchar) column.
When a supervisor is assinged a job he is sent an email but sometimes the supervisors do not write remarks about a job for some time. i want a stored procedure through which if the remarks of a job are not written for say 5 days an email is sent to the supervisor to do so? in my job update table there are multiple entries for a job so the stored procedure will have to check the Top Remarks Date for each jobOrderNo. then compare it to today date if the difference is difference is 5 days then send email. i have read posts on sending email through job scheduler but i'm new to stored procedure so have no idea how to write such.

i want to create a centralised business or Service authendication architecture in .net. for example, we have a clients like c1, c2, c3, c4, ... etc. everybody logins seperatly as well as grouply. ie, if client "C1" logins [with login authentication] he can access c2 , c3, c4 also without login authendication. So its like a google. if we enters gmail account, we can access orkut, picasa like that.. i need the cetralised architecture.
And, client "c1" seperately asks seperately how will be the authendication architecture.
so give me the single solution for both these two scenarios. how will be the architecture for these two and how is the Data Base (Login) Structure.
