Forms :: Can't Pass Variable From One Form To Another?

Jun 8, 2011

I have one form, which the user enters upto 5 websites then clicks go - I have on the second form, the one with the webbrowser. A timer which checks if the web browser is busy then either a green light or black image will be shown along side the assocaited input box on the first form.I am finding it impossible to feed variables into the clock through ByVal, like I would a subroutine or function.

Private Sub ActiveMe_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ActiveMe.Tick
If ((WebBrowser1.IsBusy)) Then
Hey.BackColor = Color.Black[code]....

'Error message says Hey is not declared, as i can't pass it through to timer

The variable Hey is determined by the first form - Which picturebox.I have an if statement which simply says if inputbox one has url enter then Hey = Picturebox1, If input box2 has url entered then Hey= Picturebox2 etc.What I want is the timer to check the page has completed loading or is still loading or refresing and the appropriate green or black to be shown aside url input box on first form.I considered using a sub or procedure to act as a clock (a large for loop with another for loop within it, acting as a delay). But found this slowed down theapp to the point of crashing it.

Pass Variables From Form To Form?

May 27, 2009

When working with a collection of forms that the user must step through, is it better to pass the data foward when creating a new instance of that form, or is it better to call a function from the previous form? I have some code written that calls the previous routine, and it looks ugly, and I can't quite think of a reason why it was done that way. The only reason I could come up with was if the data was large, and there was a good chance that the user wouldn't use the data except in a special case.

Multiple Forms - Declare And Instantiate Second Form On Program Start - Use Button Simply To Show Form?

Jan 14, 2010

I have a program that uses two forms. The program opens to the Main form, and the user can navigate to the other form from the Main form through use of a button. Here's the way I've currently written it: When the Main form loads, it declares and instantiates the other form during the load procedure. When the user presses a button, the second form is displayed by means of the ShowDialog method. On the second form, there is a Return to Main Screen button which closes the second form, bringing the user back to the Main form.

So, here's the structure of the code:

Code:
Public Class frmMainForm

Dim frmSecondForm As New SecondForm

Private Sub btnSecondForm_Click(blah, blah, blah) Handles blah, blah, blah

[CODE]...

Here's my reasoning: Originally, I wrote the code so that a new instance of the second form was created every time the button was pressed. The problem was that whatever data was displayed on the second form, previously, was lost when the user returned to it a second time. Since the user would be switching back and forth between these forms, frequently, I needed that data to persist.

What is the best practice for accomplishing this:

1) Declare and instantiate the second form on program start, as I have done, and use the button simply to show the form?

2) Declare and instantiate the second form each time the button is pressed but maintain the variables on the Main form and pass them ByRef to a custom constructor for the second form? Is this even possible?

3) Something else?
