Is it possible to clear all public variables without the needs to define one by one. It is like you press reset button in VBA. Is there any kind of code to do that?

Noob programmer here. I'm reorganizing a bunch of the code for a small crappy videogame I'm making right now in LibGDX. I'm moving a bunch of vars from a class that were declared as private into a separate class. I tried to lookup a quick way that I could change all of the vars from private to public all at once, but alas no luck. I can click on each individual var and wait for the lightbulb to show up so that I can click "change access modifier", but it'd be really nice if there were a way to highlight all of them at once and change them all to public. Bonus points if I can change them all to public and static at the same time. (I know that having a class of nothing but public static non-final vars is supposed to be frowned upon, but whatever, it makes things a heck of a lot cleaner! Don't judge me!)
You may create the search and replace template ie like follows:
then create an inspeciton from it, run and press the "replace all" button:

Probably simple question but couldn't find any working solution. I have User control on windows form. I would like on button click placed on user control to reload user control. By reload i mean to reset all its variables and show again. How to achieve that?
There is nothing that does that. You could dispose the existing control and create a new one but noone would do that. Basically, it's a manual process. If you want the control's fields reset to defaults then you need to write code to do that. You might declare a Reset method and put all the code in there if that's appropriate and then you can simply call that method from the form.
After searching for a solution on the internet, I found this on CodeProject from 2007:
VisibleWhilePrinting = false
This does not seem to exist in VB.Net. Is there something out there that I can use to hide a button when printing a form? (other than manually setting the button's "visible" property to hidden every time the form is printed).
Thanks.
Why don't you create a method that handle's this type of behaviour? The code you provided is probably a variable that is referenced somewhere in the code to determine what needs to take place, for ex:
Dim VisibleWhilePrinting As Boolean = False
Then this can be used or set anywhere and then used where you need it to. In order to hide a button just depends on why you need to hide it. As you have already stated about the visible property of the button itself. So as I have said, create a method and call it or a function...
UPDATE
As #varocarbas has mentioned, there isn't a automatic way of acheiving this, only manually.
I am making an usercontrol with only one textbox so basically I expect that properties of textbox have to be applied to whole usercontrol.
That means (for example) that I would like from outside of usercontrol (in main program which contain those usercontrol) to get value of those (intern) textbox's selectionstart property.
But I can't find a way to do this except in creating a new public property of my UC.
I suppose that here should be some better way because textbox have many properties which may be needed to read (or maybe write) from main program and making another public property in UC for every internal property of textbox don't seems like "way to go" for me.
Any advice on how to get properties of internal control in UC from main program?
you may inherit your usercontrol from textbox control,liKe:
Class MyTextbox
inherits TextBox
End class
and then try to override, overload and access the events and properties you want.
you can check the following links,

Will not a regular FindControl check solve this?
Is it possible to import namespaces in VBA? I'm writing Word macros and I want to put all functions inside Modules or Classes. But once I do that I see that I cannot reach the controls in the VBA form easily. I have to include the name of the form first, then access the control within that one. I can't just go
TextBox1.Caption
I have to go
Form1.TextBox1.Caption
Is there a way to get around this?
You shouldn't be coupling your classes/modules so tightly. A worker module shouldn't require knowledge of the Form1 class, because then it can't be used separately in another project.
Instead, you probably want to pass the function in your helper class an argument on which it performs work, and then returns the result (if necessary). As a completely useless, trivial example:
Public Sub SetLabelText(ByVal lbl As Label, ByVal caption As String)
lbl.Caption = caption
End Sub
And you would call it from within the form class, like so:
MyHelpers.SetLabelText(Label1, "New Label Caption")
That way, you can use the functions in your helper class from any form.
But, as far as your actual question, no. VBA doesn't have any concept of "namespaces". The best you can do is the With statement, but having to do this frequently is more likely an indication of a design flaw, as I discussed above.
