my program is an alarm that prompts the user if there is a new added item.
i want it to be real time so that the user does not have to restart the application to check if there is a new item.
I would like the client app being able to refresh the data every 30 minutes.
View 2 RepliesI am looking for formula that is accurate in converting Minutes to Decimal Minutes i.e 30 minutes is 50 Minutes in Decimals so 1.3 hours is 1.50 and not 1.5 i have used Minutes/60 but it is not accurate as some times i have to Multiply the result by 100 and some time 1000 to get correct results based on single digit Try 1/60, 10/60 99/60 or 100/60.What would be the most efficient and correct way to Convert the time into Minutes ?

I am working with vb.net 2010 SQL express 2008 and ReportViewer. I have created a form that a user can add, edit and delete data which is all stored in an SQL db. I am printing out reports for the user with ReportViewer. The issue I am encountering now is that at runtime if I make any changes and decided to view the changes via a report with ReportViewer, the change will not reflect. I have to close the program and open it up again so that I can view the changes. What do I have to do in order to view the changes view ReportViewer during runtime? This is my code:

I have a ReportViewer showing a report that is bound to a dataset. The dataset gets its data from a Access database backend. I have a separate form that allows the user to add/update/delete data. My problem is when the user makes changes to the data using the data entry form, the report does not reflect those changes. I have to close the entire program and reopen it before the changes take effect on my report.[code]...

View 9 RepliesOn my Winforms app, I have a primary form with a DataGridView bound to a database Entity datasource.
The grid is set up not to allow inserts. Instead I have a button on my form that kicks of a second dialog where the insert takes place (ie. with friendlier ui than is possible with the DataGridView).
The insert is working fine.. query of the underlying table in db shows that the record has been inserted. However, I can't seem to get the DataGridView on the primary form to see the new data just created by the second dialog.
I have read many Stack Overflow q & a's and tried various solutions to get the DataGridView to refresh to show new data.. but nothing works.
This must be a common situation ?? Can someone suggest some VB.NET code that will work ?

I've spent several hours reading through posts trying to make a data refresh/reload work and I can't.After adding a new record to the underlying table (using MSSQL) I need the datasource for that table to show this new record. My understanding is that using BindingSource.ResetBindings(False) is supposed to fetch a ew set of records and also update any control bound to it (ie ComboBox).Neither of this is happening. The new record is not there when using the navigator. The ComboBox does not show the new values either.It seems that this would be a simple basic command in VB, alas, I can't find a way to do this cleanly.I'm using SQLSERVER 2005 and VB.NET 2005. Controls are all bound to datasources...
