I'm trying to use mockling with VB10(VS2010) to improve my unittesting. I have a C# lamda expression example but I don't know how to implement this in a VB lamda expression? v => v.Load += null The full Moq to raise the load event would be view.Raise(v => v.Load += null, EventArgs.Empty) .Net Developer
View 1 RepliesI am developing a form application in VB .Net with a main thread and two other threads that reading values from two serial ports, do some work and raising events to return values when each thread ends.The handlers for the events are in my main thread.Is there any possibility the two threads to raise events the same time or some other event (button click event for example) raised the same time with a thread finished event? What happened then? Is there a way to make asynchronous event raising?
View 11 RepliesI am using Visual Basic 2005 Express and have 8 PictureBoxes on the Form.. When the user Double-clicks any of the Picture Boxes, the path of the image needs to be passed to a Subroutine..As of now, I have a different event for each of the PictureBoxes.. I was wondering if there is a way such that I can use a common event. i.e. if a user double-clicks on any of the picture boxes, the same event is raised ?

View 2 RepliesAs it stands, when I click a button to load the data the application lags and looks as though it has locked up although it has not. There are a lot (10,000) of records to load in some cases.
I thought I could just change my status strip text to dispay "Loading database" while it's loading.
So, I raise an event (dbloading) in the "load db" button.click event before calling the procedure to load the data. When that event is raised, I change the status strip text.... but it does not work.
Here's my
Private Sub btnLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoad.Click

i'm trying to learn about user controls. I created a user control that has a textbox and a button. What i'd like to be able to do is when i click the button in the user control, populate a label in the aspx page. I understand that i could just have a button on the page that uses some properties on the user control to get that information.. but i'd like to know how to do it with the button the user control.. the reason for this is the button is just an example.. a learning tool. if i can get this working, i'd likely be putting thing in the user control that might require this kind of passing information. Anyway.. i've found some c# examples that i tried to get working as vb.. but once started getting into the delegates and events..
View 3 Repliesi have the following problam: i have a user control which i want to raise an event from to the page that is using that user control (its a button)anyway my problem started when i wanted to put this user control inside a repeater instead of another button (regular asp:button)anyway i needed to support CommandArgument so that page can use the button,so i created a property:
Private m_CommandArgument As Object
Public Property CommandArgument() As Object

so after i press the button and the postback happen my raised event dosnt have a value..where should this property be saved in order for it to have a value after postback? view state? how do i add to the the viewstate automaticly?

View 18 RepliesProblem that you may have when dealing with two objects that are raising some events. Here, to make it obvious, I am closing the form, but the problem can be experienced with any other 2 classes event. First, what is the problem !
Let suppose that by pressing a button, you want to raise a custom event, then execute a method and then close the form
In that case, you may use a code similar to this
Event BeepIt()
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
RaiseEvent BeepIt()

I am working on a simple NES gaming reprogramming project (who doesn't try to program video games when they start out?) and am coming up with a goofy little error in my battle screen code. The Battle Screen is supposed to trigger and draw this form, but the thing redraws itself three or four times, creating an obvious and obnoxious triple-blink. Basically, the OnPaint event is still a bit of a mystery to me. Is there a way to reduce the amount of redraws so that it doesn't blink like it does?

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?

View 3 RepliesThis is not a homework of mine and i had never tried ms access database with vb so i just gave it a shot. so this is my first time and i am just trying not asking anyone to complete my homework. I have been searching for this a lot on internet but couldn't find a solution to this so i decided to ask this question here.
i have this sql code. what i want to do is that create a basic login form where users puts it's username in the UsernameTextbox and Password in the PasswordTextbox. If the the information match then a message box appears saying that the user is valid and if the information does not exist, a mesage box appears saying the users is not valid. now everytime i execute(run) the code, i come up with this error: Syntax error (missing operator) in query expression ''UserName' = 'Admin' 'PassWord' = 'testing123''.
The field names(UserName, PassWord) are also correct they are same as in the database. the information put in the username and password textbox are correct and they match the information on the database. But i dont know why this error comes up.

Since VB2005 I have been struggling with the limitaion of VB of defining an Overridable Event. This is essential for having a class which implements the NotifyPropertyChanged event (or other events) and needs to be used as an NHibernate proxy class loading). The .NET 2.0 framework itself has no problem with this whatsoever since it is supported in C#. Now I have to always include a C# base class for any VB class that needs to implement events.
Can somebody explain to me why the VB is in this case so incompatible with the C# and .NET language? Was expecting to see this implemented in VB 2008 or 2010 but neither seems to have given this (small?) syntax/compiler change any thought.
