I have one main form and another dialog box that is used to search records. What code is used to declare a public variable in the dialog box form in order to get the record found by the user displayed back into the main form?

View 1 RepliesI have 1 project with about 7 forms. On each form I have 6 x 4 responses radio buttons (i.e. a multiple choice quiz). If the correct response is selected, the examinee gets 1 point, else 0. At the end of the quiz, the examinee can click a button that will add up all the correct responses & display the % correct. How do I program the button to do this given that data are on 7 different forms? [URL].

So I'm doing an assignment with VS 10 at college that involves making a program for calculating orders but got stuck in trying to link the "invoice" listbox for the receipt to the one on my main form.
Let me illustrate my example:
This is the "main menu" is where the user adds bikes, edits existing ones and deletes if needed.
This is my receipt form, it opens perfectly fine and even shows the totals that are stated in my main form:
However, the listbox in my receipt form doesn't link or take in the information stored in my main form, which in this case, would be all the bikes. Here's my
Public Class BillForm
Private Sub ReceiptForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
What is wrong with it? The text boxes link up, but the list box always shows up empty when I try to add some bikes in on the main form.
I'm trying to generate my own dataset and create parent/child relation on the fly so that the subsequent datagridviews (dgv) that will be displaying the information will filter each child dgv by the record chosen in the parent dgv (I hope this makes sense).
So far I am able to display info in each dgv, but every record from each corresponding table is displayed in each dgv- no filtering is occuring. I think the problem might be in how I'm creating the relation and/or how I'm linking it to the dgv. Here's the code I have on the UI:

After trawling around the net for a good few days, i decided to post something here.
Basically, i've got a problem linking a data source (Access 2007 database) to a VB 2008 project.
I've broken it down to having a problem dragging a table onto my form, when it generates the nav bar, it says "0 of {0}", and the table is empty (despite the actual database containing values)
However, this happens only at home, at college it works totally fine. The only difference that's obvious is that i'm using Windows 7 at home, and Windows XP at college.
Quite a few threads on passing data from one form to another, but I'm struggling to work out how to share data between the two - back and forth.
For example:
Class1 is a class with 10 string properties
Form1 has 10 labels ("Label1", "Label2" etc) and a [Configure] button.
Form2 has 10 textboxes and a [Apply] button.
I want to load with Form1, and create an instance of Class1. Click the Configure button and load Form2, passing Class1. On Form2 I want to manually fill in the 10 textboxes and hit Apply. The Apply should update the Class1 instance and close the form.
Form1's Label controls should then be updated with the data from the Class1 instance.
I'm fine creating the forms and classes, as well as passing the class into Form2 with a custom Sub New(EmptyClass as Class1) constructor. This gets the empty class into Form2, but how can I get the populated class back to Form1?
As Form1 already exists I don't want to create a new instance with another custom Sub New(PopulatedClass as Class1)
It's also key to be able to use the Form2 multiple times, basically ending up with a Data class being displayed as part of Form1 but updated using Form2? (For example if the Class has already been created and populated with data when it's passed back to Form2 for the second time I would pre-load the Textboxes with the values already in the class).
Passing data between forms without any public methods or properties on the forms. everything but the "Controller" class, which I would like you furnish. I just changed the title from "Intermediate" to "Beginner" This solution is an example of the Observer Pattern. The "Controller" class is the "observed" class, which in this case means it publishes events.
' File Definitions.vb
Public Delegate Sub MessageDelegate(ByVal sender As Object, ByVal e As MessageEventArgs)
Public Class MessageEventArgs : Inherits EventArgs
Public Message As String
[CODE]...
The program should initially display Form1, and Form2. Clicking of the button on either form will modify the Title Text of both forms. I think that you will find the final end result to be pretty neat, as it works with any number of open forms not just two. I think asking for the Controller class is easier than asking for the code in the forms. My solution for Controller class has 7 lines of content, 9 lines if you include Class, EndClass. A minimal solution could achieved with only 4 lines of content, but it would a textbook example of bad programming.
How to create a data forms with the data forms wizard in VB 2005
View 6 RepliesVB.NET newbie here... I have an vb.net windows application set up. It has multiple forms, about 6 in all. There's a main menu form, and then 5 other forms to collect data. The user will collect data on each form and bounce back and forth between forms. How do I get the forms to retain the data that has been entered into the text boxes and/or other controls on the forms? For example, they might fill out a few textboxes on a form, but then need to go to a different form and fill something out... and then back to the previous form. Right now, when they come back to the form, all the data previously entered in to the text boxes is gone.

View 3 RepliesI am INSERTING into 2 different tables with 2 different buttons (One after the other by clicking each button). I have a form with 1 button directly on it to INSERT into tblCustomers from a field that is directly on the form as well. I then have a TabControl with another button with other fields (5 to be exact).
After I add data to the data base by filling out the field on the form and then by first clicking the add button located directly on the form and then add data to the fields directly on the TabControl the data will not INSERT itself into the tables in the data base for the 2nd table. Only the first table get data in it and not the one related to the TabControl.
BUT if i add data in the TabControl and then click the button on the TabControl it adds data into to the 2nd table. Is there a way to refresh my program so that it will accept both the "forms data" and the "TabControl data"?

I've recently decided for my VB final that I'd like to tackle something my professor and I discuss constantly; portable game server apps.
What I'm wanting to do, essentially, is create just a rudimentary programme that allows you to check the server status of either the north American or European servers for the game Rift and just (instead of opening your default browser, which I know how to do already) displaying the info in a listbox inside the programme itself.
The information I have to work with (aside from the obvious direct .php link to the web page) is two separate .xml links that contain all the information that is contained on their webpage. I could easily just turn these .xml files in an access database but I want something dynamic rather than static, but I honestly have no clue of how to turn this info I have into something I can actually use in my programme lol.
I'm creating a system (for a project) that is based on a vet.I want to create a combo box that has a list of different animals (e.g. Dog or Cat etc.)and when an animal is selected,a group box, with loads of checkboxes inside appears. Then the user can tick a check box (a vaccine to be given to the animal) and the record is saved to a database.I have hard coded this to work, but I want a more sophisticated code set, that links to SQL so that when a new vaccine is to be added, I would only need to add it in a table, in the database. I don't know where to start for this could any one give me a nudge in the right direction?
