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

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.

If I Change Visibility of Form1 when Form2 is opened upon Retun to Form1 Data is reloaded, if I minimise Form1 when Form2 is opened upon return to Form1 Public variables are reset to defaults.I have many Forms with many controls and buttons to do Lookups or additional add to related tables.

I seem to be running into an issue. This may seem like a noob question (which it really is, I only have experience in vb6 from years ago) but what Im trying to do is pass a variable from one form to another. Ive tried telling the first form to set the value of the variable on the second form like so frmsecond.variable = "value" but that does not work. Ive tried placing a public variable in a module to do it, but again, no luck. The only way seem to be able to get it to work is the second form setting the variable by reading the value from the first form like so [code]The problem I have with that code is what if for some reason the selected line gets changed as the form is loading or something to that nature. It doesnt seem very secure.

With the text file being called Player 1, player 2 etc etc, and the first line inside the txt file to be their name., I'm getting the "player 1", "Player 2" part, but the first line is constantly coming up with "textbx_1" instead of whats inside the Text box.
View 4 RepliesQuite 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).
I will try to explain what i want to do.I have make 3 textbox in form1 And i have a form2 where i have a Textbox ( Multiline )What i want i want to have the text from the 3 textbox to my textbox in form2.
textboxt1.text = tennis
textboxt2.text = boys
textboxt3.text = 01-01-2011

I have a function called textupdate that updates text1.text value. when i call this function in Form1_Load, text1 is updated successfully. However, when i call this function in Private Shared Sub function2, no update is done. I am a newbie in vb.net programming and it may be a silly question but I could not solve it

1. I have a multiline texbox and want to know if there is a way to search for a text in the textbox... The user should be able to input a search string and click a button to search all the entries of the string in it, just like ctrl+f
2. Is there anyway to make the textbox 'read only'? The textbox is populated by application itself, with some logs.. The only reason I chose textbox was because, I can't select an item and copy it from label..
Also, can a textbox include formatting, such as making some text bold, underlined etc?..
Can i get text from a textbox and use that text for the second forms code?

aligning text into columns in a textbox.
I need it to look like the following:

XXXXX XXXXX XXXXX XXXXX
I've seen several representations of how to do this in VB6, but I would prefer managed code (VB.net). Also, I want to make sure that what appears in the textbox will translate to the printed page the same way.
I got a Sub which processes a code, and then it does whatever the code said. Example.
Code = "Black" -> Turns screen black.
Code = "OFF" -> Turns off the PC.
And so on.
If I call that Sub from Immediate console, It works perfectly. But if that Sub is called from an event, It does nothing, and usually throws an Exception. I read somewhere that I can fix this by using Threads, but I don't understand how that can help and make it work.
