Asp.net Mvc - Refresh Database?
Aug 23, 2011
I was creating an mvc application and i had a model class with a dbcontext function the variables were in the same file. I added another field and changed the code in the edit create delete details and index views but i now get an error saying "The model backing the 'GameDBContext' context has changed since the database was created. Either manually delete/update the database, or call Database.SetInitializer with an IDatabaseInitializer instance. For example, the DropCreateDatabaseIfModelChanges strategy will automatically delete and recreate the database, and optionally seed it with new data."
Imports System.Data.Entity
Public Class Game
Public Property ID() As Integer[code].....

How do you refresh a database connection within a VB application to SQL Server 2005 so that whenever data is changed in SQL, such changes are picked up by the application? For now the application only picks up the changes after it has been restarted, and that is not what I want.

I am in a situation where I have a tool which is always running. Now if any new entry is added or deleted from the database then unless we dont restart the application it will not reflect the changes. So I want that the application itself should check for the updates or at least it should refresh itself.

I have a datagrid view containing a customer list that if if double click on a row it brings up a customer maintenance window. Once I hit a save bottom on the second form how can I automatically update the database, refresh the grid on the initial window but remain on the same row on form1 that I double clicked on in the first place. Currently I am re-loading the datagrid on the initial form with all the data once I close the second window down.

I am working on an application that ties into a SQL database on the back end. Currently the main form contains a series of combo boxes (Graph type, data format, location, and customer), two date pickers, and a button to launch the selections in a new form. Everything works just fine except there are a couple of things I can't seem to accomplish.
Example Data:
[CODE]...........
Case Select (with commented out lines for variations attempted):
[CODE]..........
1) I would like to be able to use some sort of case statement to color the bars in my chart based on value. I have tried approaching this in a couple of different ways but neither of the options seem to work. First, I tried this (the If Not is used because depending on what values are passed to the stored procedure in SQL, different columns will be returned):
[CODE]..........
Only one series is created with this method, so I can see how/why a Select Case would set all bars the same color. I have also tried creating a series for each row in the returned dataset but it results in 22 bars of different colors, for each of the rows (484 bars):
[CODE]..........
So is there any way to modify the second set of code there to only select the value from the "Percent TMHB" cell that corresponds with Row(i), rather than ALL values from the "Percent TMHB" column for EACH Row(i)?
2) Since I am drawing/creating these graphs in a new window, is there any way to also create a new timer on the "newFrm" and have the tick refresh the data? I've struggled with this but I feel like it should be easy. Say someone chooses a "TMHB", "Percentage", "Chicago", "All" (Graph type, data format, location, customer) and launches the graph, which opens in a new window, then they want to do "TMHB", "Percentage", "LA", "All" and have both windows up, refreshing automatically throughout the day. Can I somehow store the SelectCommand.Parameters values in the new form/timer so that it will query the database again every 5 minutes?
Example code for the StoredProcedure and creating the new form:
If combo_GraphType.SelectedItem = "TMHB" Then
Dim newFrm As New Form
Dim newChart As New Chart
[CODE]..................

I have created a simple VB.NET application with one form and a few modules. When a user clicks on a run button of the form the application starts and goes through differet cycle, while updating the user on status bar, runs for less than four hours.
The application works fine, it gives desired result. However, it is not able to refresh the user form, meaning status bar remains same after some time (it suppose to increment). Even when I take mouse on the form it shows timer symbole instead of default one.
My application commands another device using GPIB. Basically, PC running my application commands the device. If I look the display of device it gives correct information.

I have a form, with a datagridview. I can see the data and the related records in the DGV.I have another form that this one calls to add a new record. I need that because there are some specific parameters i need to control. But when the focus returns to the original form, I can't see the new record, even though it is there (I see it in the database).If I close the form and enter again I can see it, that is not what i want.How can I refresh the tables after the other process adds data to them?

I'm making a calculator for a finance company, it keeps track of how much money,bills, and all the totals of everything, and how much your budget is and so on.I have to have it run automatically, by that I mean no buttons at all. When a user enters a new bill or new payment, I want all the totals to reflect the change, say if I add a new bill, my budget will decrease, and so will how much money I currently have.Here is an example I've made up to show what I've done:In this sample, I have one textbox named TxtTotal, it populates all of the payments you have received, in this case up to 5 payments. I'm kind of confused on how to currectly refresh all the data. Right now I have this timer that will refresh the application every 6sec. Thats currently my problem, how do I get the this textbox to populate all the data on its own without using a button.

Sub TxtTotal_TextChanged(ByVal
sender As System.Object,
ByVal e

I've got a windows form app that displays people and their addresses.A person can have more than one address, one of which is their primary address.The user navigates to the person desired then clicks on a button that displays a form that shows addresses, one at a time,for the person. The user can then navigate thru the addresses.On this addresses form, there is a checkbox to designate if this is the primary address.The user can change this designation by navigating to another address for this person and clicking on the checkbox.There can be only one primary address for a person.
So if a person has two addresses and the first address is primary, and the user wants to make the second address the primary, then they navigate to the second address and click on the primary checkbox. This is checked for the second address now and should be unchecked for the first.
The programming to change the primary address works just fine. The database is updating properly. The problem I'm having is refreshing the checkbox for an address that is no longer the primary.It's still in a "checked" state. I have to close the addresses form and reopen in order to get the checkbox refreshed correctly.Is there a way to refresh the checkbox without having to close the form?

I'm using Mysql database and Visual Studio 2005. I've got a form with datagridview, After making the changes in the data, it is saved in the database. The data gets saved in the database, but the modified data does not get displayed in the datagridview. Only if I close the form and open it again, the changes are displayed. I want to provide a button (refresh-button), which on clicking will refresh the datagridview, so that the modified data is displayed without closing the form.
