I have a CheckingAccountForm and a CheckingAccount class. I have 2 variables AmountEntered and TotalAmount. The user enters an Amount and hits the calculate button. So now I send the AmountEntered to the CheckingAccount class where it is added to the TotalAmount and I have to send the TotalAmount back to the CheckingAccountForm so it can be displayed in a textbox. Can someone give me an example on how to do that? I get the AmountEntered to the CheckingAccount Class and managed to calculate, but not sure how to get the TotalAmount back so I can display it in the GUI's TextBox for the TotalAmount.

View 5 RepliesI am returning to programming after a long absence (last real work done in VB5.0). I'm trying to do a small customer management project. I'm starting off with a DataGridView on one form showing a reduced number of fields. When the customer is selected a second form gives the full details. I struggling to find a clean way of passing the selected record to the second form. Both forms are using the same dataset.
View 5 RepliesI have a search page with a couple of pulldowns. Dependig on the values of them I show a grid matching the searched criteria, basically a table with links the user can navigate to. My problem comes when the user wants to navigate back. At the moment I have a "Back" button which simply redirects the user to the initial search page. I think it would be a good improvement to have the values of the pulldowns filled in with the values the user selected, this way when he presses the "Back" button he would not have to restart the whole search process again.

To make this easier I will use a concrete example using movies and genres. A genre can be associated with many movies. Genres can increase over time and so can movies.
The use case is as follows. The user wants to filter movies by selecting his/her desired genres.
So, I have a page where at the top there is a section where the user can pick any combination of genres to filter on using checkboxes. Below that is a list of movies that are in those genres.
In MVC I am trying to implement this using a ViewPage(of IDictionary(of Genre, Boolean)) where the boolean is whether or not a particular Genre has been selected for filtering.
I then go into loop that creates checkboxes for them to select:
<% for each genre As KeyValuePair(Of Genre, Boolean) in Model %>
<%=Html.Hidden("genre[" & i & "].Key", genre.Key.ID)%>
<%=Html.CheckBox("genre[" & i & "].Value", genre.Value)%>

Ok, so I have a small program I am building for my boss to keep track of workers at certain job sites. With the way the economy is going my boss wants to track who is showing up at specific sites (jobs) and try to even it out among all the employees - some are not working full time.
Anyway, I have two Access tables linked together with the main table being Employee Data. The second Table is Employee Jobs. Basically I have three forms. The main form on startup will show all of the employees in the company - this is basically a list of all added employees into the database (this is the second form - adding employee info). At a quick glance I would like to have the initial startup form, with grid - show employee info, show the number of jobs each employee has been assigned to. Would this be an SQL statement? How to I get a row count and post that back to the grid so it shows up on startup?

How do I change this so that the javascript fires, runs my validation and then hits this controller action?
My code behind is VB.NET. I use ASP.NET UpdatePanel like the following. However, after the post-back, it locks TextBox controls , I cannot type anything, except when I move the mouse over and click on the TextBox.
why it locked all TextBox controls after the post-back?
Here's why I use UpdatePanel:
During the post-back, after inserting data into DB, set all TextBox text property to String.Empty After the form is submitted, the Panel pStudent should be refresh , not the entire page and the TextBox txtId should be in focus again.
here's the mark-up of the ASP.NET page: [URL]

View 2 RepliesI am making a program using Windows Form Application, and I had it set up in the design view. I double clicked a button to begin coding and up popped a ton of stuff in the code view that I had never seen before. I closed that, and somehow closed the design view by accident too. Now I can't get my design view back, even by re-opening the program (I didn't save), and double clicking the form to open it. It opens up as "Form1.vb" rather than "Form1.vb [Design]".What happened, how can I fix this and get my design view back?

I have tried currency manager also.The problem i am incurring is that when i click button next it goes forward 3 records then loops back to the first record again. If i skip to the end of the dataset i can browse back 26 records before it loops back ot the first record and gets stuck in a loop.
