Handles Error In Exit Box?
Aug 9, 2009
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'

I am in the processing of moving an app from VB to C# but some of the classes I will just be moving to VB dlls to access from the main C# app. In doing this I am trying to get the VB dlls to utilize the main C# class lib. In this C# lib I have an abstract clase called base process, it sets up a background worker and handles all the progress tracking, errors, and even reports an ETA. To use this in a derived class in C# you would just do this...
public class SomeLongProcess : Common.Multithreading.BaseProcess
{
public void start()

The problem is that if I do the equivelant in VB I get an error "Handles clause requires a WithEvents variable defined in the containing type of one of its base types". Well I can't do a WithEvents in the base class because it is C# so..

When I close my VB.NET application it occasionally yields the following error code: The program '[1584] Foo.exe: Managed' has exited with code -1073741819 (0xc0000005). This error only occurs when one of the MDI child windows is maximized and then the program is subsequently closed. When I step through the code, the error appears to be generated after the execution of my "custom" code is complete. What might be the cause of such an error? Where might I find more information about this exit code (Google and Bing were little help - maybe I didn't search for the right thing)?

I'm having a bit of a problem getting my application to close properly. Basically I have one main form from which all other forms open. If a user tries to close that main form, I want to bring up a MessageBox asking if they want to exit the application.However, when I try to do that it asks the question twice. It seems that the Application.Exit() is triggering the FormClosing event again for some reason, but I don't know of another way to exit the application. BTW, the main form isn't the startup form so I can't use the option to close when the startup form closes.

Now I have a sub to validate a bunch of textboxes and combo boxes.I previously used many IF statements to validate and pop up different messageboxes and Exit Sub in every IF statement.But I heard that too many Exits will decrease the efficiency and they were not recommended to use. Instead, nested IF is better because it will let the process naturally go to the end.Then I found out that if I use nested IF,it will be hard to read, since messageboxes are all separated from conditions.

When I attempt to run a program I just finished coding I get the following message: "Error 1 Handles clause requires a WithEvents variable defined in the containing type or one of its base types." Looked it up online and still does not make sense to me. If I need to paste code or anything else let me know and I will do so ASAP.

Protected Sub Menu1_MenuItemClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.MenuEventArgs) Handles Menu1.MenuItemClick
End Sub
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
Dim Browser As New System.Windows.Forms.WebBrowser
Browser.Dock = System.Windows.Forms.DockStyle.Fill

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
[Code].....
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?

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 already have a loop in my script so i can cycle through my textboxes ("TextBox" & i.text). is there anyway to use a variable or a function after handles to get all the names of the text boxes?
Private Sub textChange(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress,TextBox2.KeyPress, TextBox3.KeyPress, TextBox4.KeyPress, TextBox5.KeyPress

What i want to do is grab the handle of a webbroswer control and only read the co-ordinates within those bounds. I have successfully manager to do this but the problem i am now having is moving the mouse to those co-ordinates, for some reason after getting the handle and moving the mouse:
Windows.Forms.Cursor.Position = WebBrowser1.PointToClient(New Point(x, y))
It still reads full screen co-ordinates.

sub I use on all forms in my app I would like to put in one central place (of course right). in vb.net I put this sub in a module it has a "Handles tabcontrol1.Drawitem" - I get an error saying handle requires with events variable defined in containing type or one of its base types.also when I refer to tabcontrol1 in a module it wants to know which form.. Can I use sender to define current calling form?

Dim g As Graphics = e.Graphics
Dim tp As TabPage = sender.TabControl1.TabPages(e.Index)

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
