vb.net - Visual Basic setting a global variable making my code DRY -


How can I customize my code to make it a dry approach? So I want to make my variables to be public / general I can use it again 

  public class BasicForm retarded product 1, PRODUCT2, Product3, Integer Dim firstName, lastName String Private Sub btn_getValue_Click as (ByVal in as the System.Object, ByVal e System.EventArgs) handles btn_getValue.Click 'set variable' product 1 = val (tx_productfield1.Text) PRODUCT2 = val (tx_productfield2.Text) as calculate Product3 = val (tx_productfield3.Text) '' tx_totalValue.Text = product 1 + PRODUCT2 + Product3 end Sub end class

May include anywhere and variable (product 1, PRODUCT2) that I set it once and want to move can easily reach other control I set alway variables to every control what I did before.

Please advise.

Thank you!

I'm not sure I get your question, because you're working in a classroom Am right, but do you know your variables are variable variables?

Your "product" variable should be a private example, or public property. If you use personal examples, then tell a way to reach variables, say a garter method otherwise the "property" is just fine. 

  public class basic form Public Function getProduct1 () 'Back to product 1 end function as integer ... different recipients at private product 1 integer as personal product 2 Personal Products 3 rounds As the end class

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
