I need this program to add the first numbers. then devide the first number by the sum of num1@num2 then * it by 100. This is what I have. Private Sub btnCompute_Click() Handles btnCompute,Click
Dim num1, num2, sum As Double
num1 = CDbi(txtFirstNum.Text)
num2 =CDbltxtSecondNum.Text)
sum = num1 + num2
Dim percentage As Integer = Cint(num1 /(num1+num2)* 100
All it will do is add the first numbers.
In vb.net I can do
private sub button_click(sender, e) handles Button1.Click, Button2.Click etc...
do something...
end sub

here is what i want to do:
Private Sub UpdateButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles UpdateButton.Click
MyUpdate.CheckUpdate("version.txt")

I have two forms. Form 1 you click a button, and it opens Form 2. Form 1 is still open.
When you click a button on Form 2, I want to run a Private Sub that is on Form 1, whilst Form 1 is still open.
The idea is that the data i've entered on Form 2, once I close this form, I can continue working with Form 1 with the updated data without having to close and re-open it.
In ASP.NET using VB.NET, you can define the wired up button click event (to an ASP.NET server control) in 2 different ways (for the purpose of this conversation - manually wiring up via button property not in question here):
Double click on the button in the designer which produces an event in the code behind with a Protected method.In the code behind, select the button from the list of controls, and then select it's 'Click' event. This produces a Private method.I understand the difference between Private and Protected; why based on how the wired up event is autocreated it generates a different Access Level on the method?
I've created my own ascx control with button inside it. Now I'm using this control inside other control. (In my case it is a webpart). What I would like to do is program button.click logic from my custom control inside webpart

In VB.net, we have the Handles keyword, I'm wondering if C# has anything comparable. Or do you have to manually wire all the methods to each control's event (in ASP.NET especially)?
The short program below runs just fine when it is the only item on a form. However, when I put it into the ItemInsertTemplate of a ListView control, I get the following message:
Handles clause requires a WithEvents variable defined in the containing type or one of its base types
Line 30: Protected Sub btnDate_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDate.Click
The error message identifies Line 30 as the problem.I get the same message for Sub clnEvent_SelectionChanged How do I correct this?

I am making a webbrowser and I am now trying to make the XButton1 go back. I have that working but I can not get it to work when the WebBrowser is active. My cursor has to be over the form (Me.MouseDown) I can't use WebBrowser.MouseDown because there is no browser until the application is opened. It is a a tabbed browser. The first browser is created like this.
Try
Dim Tab As New System.Windows.Forms.TabPage

Using Visual Studio 2008 I am trying to create two subs using the same handles:
Private Sub checkwin(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click, Button2.Click, Button3.Click, Button4.Click, Button5.Click, Button6.Click, Button7.Click, Button8.Click, Button9.Click

As these both use the same handles one sub overwrites the other...... Both subs contain If statements. Do I need to create two different handles... and how do I do this so that the handles use the same buttons?
I have a simple program that was written to access data from multiple access tables. I have everything running perfectly however I did encounter an error with the exit button. I have removed the control from the window and replaced it with a exit button on the form. However I am getting an error reading: "Handles clause requires a WithEvents variable defined in the containing type or one of its base types."I am a little confused because I have this exact same line of code in two other programs and it runs fine. I have read up on this and I know that I need a line of code that reads something like " Friend WithEvents Button1 AsSystem.Windows.Forms.Button" However I am not real clear on what friend means here and where exactly the With Events goes in my code?
Code for exit button
Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click'The problem is with this line of code'

Is there a way to simply the Handles statement? What if i want this sub to handle 20 textboxes do I have to list each textbox there?

I've been using Shell() to launch an application, and Process.GetProcessById() to get the handle to that window, but I think I'm running into problems when passing the handle around to various functions. What is the best way to declare and pass windows handles so that they will be usable? After viewing the debug, it seems the Shell() and Process.GetProcessById() work fine. After I pass the handle off to the functions I need to use them in, the program starts spitting out garbage, and not doing what I want it to do. Short version of the proces
