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 A Variable From Xaml To Program?

May 8, 2010

I know I gotta get a book or something because things are just way too hard for me. But before that happens I have what I think should be an easy question.

I want to create a variable in xaml, the angle that a control is currently at, and then use this variable in my VB code (event handler).

Or even better can I, while in VB code, check the current angle a specific control is at so that I can add to the number when setting the new angle?

Pass A Variable's Name Along With The Value When Passing Through Functions?

Jul 6, 2009

I want to know if it's possible to retrieve the variables name from when it was passed into a certain function. For example, if I call parseId(myId) to a function with the signature parseId(id), i can obviously retrieve the value of 'id'. However, is there any way I can retrieve 'myId' as a string (without passing it as another value)? Specifically in vb.net, but I'm interested in how it would work in any given language.
