Create And Save Data To New Forms?
Jul 1, 2010
New to vb.net coming from vba. I am working on a mass balance model which collects a handful of 'user' data (less than 10 records) and then applies various equations to the data and records/reports the resulting values. I think I have a pretty good handle on the basic operators for a single 'user', having pretty extensive vba knowledge. However, I am having difficulty saving the new 'user' data and creating new 'users'. I need to keep the app as simple as possible for deployment to machines with nothing more than 2.0 and I do not really need a database, just a simple method of creating multiple 'users' as objects.

I have three tables under one database. I'm using the built-in Navigator control for now until I get this figured out, but I'm using a button command instead of the built in navigator button. I need the "Save" button to save the data in the text fill boxes to save to the corisponding table. I used the drag and drop option to drop rows from each table to the form. See code:
Private
Sub Button1_Click(ByVal
sender As System.Object,
ByVal e

I made my first app today. The point is to enter a password and then get into a screen that displays info, and you can edit it by typing in the text box. Is it possible to save the data typed?

I've got a small reminder application I wrote in VB Express 2008. The main app autostarts with Windows and sits in the system tray all the time. Now, I need to save the time (sorta timestamp) it closes/terminates to a file. It works fine when the app is terminated by myself but doesn't when when I shutdown/reboot Windows. The code that saves the timestamp to a file resides in FormClosing event. But for some reason it doesn't fire or the code to save the file doesn't get executed when I shut down/reboot windows.
Is there a way, probably thru' Win API to register my app with Windows, so that windows actually waits for my app to terminate in a sane way after saving the data. I remember of reading about this possibility somewhere, I don't remember now.

I would like to commit the data put in a checkedlistbox to the user.config. I have found a way to commit them to my.settings but no matter what Save() method I call, it does not commit the new data (that is not bound to a control, through the propertybindings) to the user.config, either immediately or when I shutdown the application. Which means, when I loop through the settings when the application starts back up, the data is not there to be added back to the checkedlistbox. I have put save methods in the formclosing events as well as when the data is created in the my.settings. using my.mysettings, my.settings and my.settings.default. Thank you in advance for your input.
This first method is a called when a button is pushed. it checks the text and then calls the next method (AddProperty) which should add the property to my.settings and save it to user.config, but my understanding is that it is not written to the file till the applicatoin closes.

I am currently generating paper forms from backend database using reporting facilities in vb.net apps. I am now required to turn these reports into PDF forms that can be sent via email to clients who can then fill in the remaining fields not filled-in in the first place at form creation.

If I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?

what the results I need in a Windows Form Application.
Requirement:
(1) I need to create class objects with all various methods and properties, etc.
(2) I will create only one instance of the each class
(3) I need to be able to call the methods and properties of the created class objects (1) from any form I create.
(4) I use the class objects to store data so that separate threads can access them..
Question: how I would code this into a WFA? (I have console application code that works but need to convert it into a GUI).

Basically, I want to create a timer for each row of data that will get returned by a SQL query:
SELECT * FROM Projects
I would want the timers to be called "Compteur" & ROWID. This really is necessary.I need them to have different Ticks and so that some can be enabled all at once. Basically it is for a project tracker to count the time you are working on the current project. However you could indeed work on many project at the same time.

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).

in my form i have 4 textboxes and i want all not to be empty while saving the data.I have put condition in save button,when user presses the save button to save data, to check all the textboxes not to be empty. My question is that, i want to focus to that particular textbox which is empty during saving the data.
For example: i have txt1,txt2,txt3,txt4 as textboxes in the form if txt1 is empty while saving, the focus should switch to txt1 rather user himself have to go there.

I've designed my own encryption application in VB 2008 that has a free tools section where users can choose a particular wizard to use from the drop down. The javascript wizards display the code required to put in their own sites. I already created wizards that users can well, use.I see people have their own "contact form wizards" on their websites all the time. Where users can use the wizard and get the displayed code to copy and paste on their sites. But trying to locate source codes to these things is very aggravating on the web.So what I want to do is create my own "form wizard" like out of javascript, that allows the user to put in some information then get the displayed code to put in their own websites. I'm not looking for the generator such as the online form generators.But the javascript source code(s) for the generator itself.Then I could simply put a form generator inside of my VB-app, that will allow the user to use the wizard, then get the html code to paste in their own sites. Preferably not the PHP one because the php backend is very difficult to put in a VB app.I know that it can be done. For example copying a web pages source code then putting it inside a string, then calling that string from a button click that will open the javascript page in the webbrowser inside the VB app.

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.

I am re-doing part of a GUI for my project, The Windows Alias Generator, and decided to switch to MDI. The child forms consists only of RichTextBox1. Here's the generate routine called when the save is clicked:
Private Sub SaveAsToolStripMenuItem_Click(ByVal sender As Object, ByVal e As EventArgs) Handles SaveAsToolStripMenuItem.Click, SaveToolStripButton.Click
Dim ActiveMDI As Form = Me.ActiveMdiChild[code].....
But because I cannot define richtextbox1.text from the currently active MDI, I cannot use this routine...my question is this: How would I get RichTextBox1.text from the save option in the MDI form?

I've written a very simple program that writes a tiny "config.cfg" (text) file to the computer (using StreamWriter), and a second program that is supposed to read that data back.
Unfortunately, it appears you can't save to the same folder as your program under Win7 ("Program Files (x86)" is a restricted folder.) So instead, VB automatically saves my data to the "C:Users(myname)AppDataRoaming..." folder. This is annoying, but tolerable.
PROBLEM IS: How does my second app then FIND my data file (without doing a time-wasting drive search every time the program is run?)
My code:
' Program #1:
Private Sub cmdSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSave.Click
Dim FileWriter As New StreamWriter("config.cfg")
