The problem seems to be that the codes below are events and cannot be called directly. I want to know how I can properly use the RaiseEvent statement while still keeping these where they belong, smack in the middle of the rest of my huge code:
[Code]....
If NewEntryName.Text = "" And OpenFileDialog1.FileName = Nothing Then MsgBox("Please choose a name for your game.", vbExclamation) MsgBox("Please find your game.", vbExclamation) Else Button1.Text = NewEntryName.Text

I have a routine in a custom class that is assigning values to an object based on data from a table row. However, several tables may be used to update these values and only have some of the fields in common. Therefore, I want to check each field value to make sure it exists before I attempt to access it's value to assign to my object. However, I am getting the error "Column x Does Not Belong To Table."
'error occurs on first line
If Not memberRow.Item("nickname") Is Nothing Then
returnval.NickName = Trim(memberRow.Item("nickname").ToString)
End If
I want to know what's the right way to work with objects that belong to a category.I'm building an applications with the following layers:Base data access Data access Business logic + Factories Presentation.I want to pass only objects to the presentation layer and back.I have objects (Employees), that belong to a certain category (EmployeeCat). I was wondering if I should have just an EmployeeCatID property in my Employee class/object, or an EmployeeCat property that contains a complete category object.If I want to fill a GridView with a list of employee objects as datasource, and I used just an ID in my Employee objects, then I will have some work at the presentation level to display the category names, so I think. On the other hand, if the list of employees contains plain category objects... I'm not sure what will happen.

I have client/server app.I have a class for the tcpclient and a class for the tcplistenerIn my tcpclient class I have a system.timers.timerThe timer elapsed event fires a public event(in the tcpclient class) which the tcplistener class handles.During debugging I see the timer firing its elapsed event and calling raiseevent on the public method, yet the event is never fired in my tcplistener class.

I'm working with RaiseEvent and have a question. Can an event in a class be raised from another class, or only from within the class itself? How does RaiseEvent differ from calling a Sub, other than the syntax of having an event and using "handles event1"?
View 2 RepliesI'm having an issue with rasing an event. In my application I have a form and within that form I create an instance of a class (clsUsage). Within clsUsage I create an instance of clsUser which does several checks form permissions and other things. What I want is for clsUser to send status updates to clsUsage. ClsUser will be a dll but for now I've got it as a separate project in my solution. The RaiseEvent in clsUser seems to execute but the proc in clsUser that handles the event does not execute. I'm wondering if this is threading issue.

I am using RaiseEvent in a thread and I pass a value to it and try to set a control's text to the value. Except I get a cross-thread error which is expected. I could invoke the control, but I don't want to have to do that.
My question is, is there a way to invoke/delegate the RaiseEvent itself so it will work on the ui thread without doing anything else?

Without debugging the events are raised just fine and working.However, when debugging and trying to change execution step like dragging the execution step to the raiseevent in the other condition block, the event doesn't fire.
I am having issues with a user created event being detected by the event handler. This program is in VB.net, defined in an OO way, and there are several other classes that implement the same interface and their class instances all detect the appropriate Event, except for one.
The following code is the base class:
Public Class CommandSpeedTest Implements testInterface
Private SpeedTest As New ArrayList()
Public Event testComplete(ByVal test As IEnumerable) Implements
[Code]...
This exact structure is being applied to three other classes (all of which are instanced using WithEvents in class gui) and being cuaght correctly.
Single stepping through code just executes the RaiseEvent line and goes to the next. It should jump to the event handler and execute the code there.
