View 3 RepliesI have 2 project in my Solution. Lets say Proj A and Proj B.Proj A is having my custom event. and same Proj is Raising that event using RaiseEvent Function of Vb.net And Proj B is having reference of Proj A. but my custom event cant raise. Could any one can explain me how can I do that.?

I am calling handleSwipeCardRequest function first and then Raising its event.
may I know what do RaiseEvent do?It raise event. But what kind of event? And what does the event do?
View 2 RepliesI converted the below C# to Vb.net
public event SendMessageResultEventHandler SendMessageFailed;
protected virtual void OnSendMessageFailed(SendMessageResultEventArgs e){
if (this.SendMessageFailed != null)

I have the following code:
Protected Overloads Overrides Sub OnInit(ByVal e As EventArgs)
MyBase.OnInit(e)
Dim login As Login = TryCast(Control, Login)
[Code]....
I get errors on line 7, 8 and 9 stating that I should use RaiseEvent to obviously raise an event. I am stuck with this after searching google but I can find no real explanation of this in terms of the login control
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.
View 1 RepliesI have a situation where I want to run the code in the Tick event ONLY ONCE not on the interval i have the timer set too.So I figured I would just do thisRaiseEvent MasterTimer.TickBut that gies an error saying mastertimer is not part of the class.Why won't that work?How do I call the Tick event manually without Start() Stop() the timer?

This is obviously a very basic mistake on my part but I am missing it completely.Here is the code
Public Event DataReceived(ByVal sender As Client, ByVal message() As Byte)
Public Event ErrorMsg(ByVal sender As Client, ByVal errormsg As String)

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?
I have an app which has been working fine for about 2 months. Yesterday, I carried out a maintenance session which was mainly simple bug fixing and moving my code into regions to help navigating through it. Along the way, 2 things have started happening which has totally broken my app.
MSDN states that Application.Exit does not cause the Form.Closed or Form.Closing events to fire.[URL]..However, my Form.Closing event is firing immediately after Application.Exit which is in a button click handler on the form. The code is like this:

As the subject says, I was wondering what's the difference between the InvokeMember("click") and RaiseEvent("click"). Also I see around example of InvokeMember("onclick"). What's the difference with just "click"?
View 1 RepliesI have this code in my application
If _oCurrentCall.CustomData.Length > 0 AndAlso UsageType = UsageTypeEnum.Vanlig Then
RaiseEvent NewIncomingCallWithCustomData(_oCurrentCall)
ElseIf UsageType = UsageTypeEnum.Sentralbord Then
RaiseEvent NewIncomingCall(_oCurrentCall, Queues)
End If
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.
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:

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.
I have a class in VB.NET that has a method (called CurrentValue) that returns a number. There is also an event that the class raises to indicate the number has changed. In the event handler on my form, I update a textbox using the exposed method.[code]When I run this I get a "Debugger.Runtime.CrossThreadMessagingException" error. What could be doing this? I am instantiating MyClass in the same form that contains the textbox.I can also set properties of the MyClass object without any trouble.

I found that when group by multiple values does not work well with VB.NET, but it works well with C# ,here are my code, is there something wrong with my VB.NET Code? Here is my VB.NET code:

I have a Windows Form that contains a custom control container as a UserControl. For the sake of this question, this custom control container is called Dashboard. This container called Dashboard contains numerous other controls depending on their permissions. I need to raise events that are contained on these controls through the Dashboard control and over to the Windows Form.
How can I bubble up the event? I'm using VB.NET for this project, but can convert C# into VB.NET.Also, to complicate matters, the main Windows Form is a VB6 project. So, I'm using the InteropFormsToolkit to accomplish this.
I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.
I have a form that works on my local Machine I created into. I have Office 2007 on this machine. I created the Form with the Excel 12 Reference. I move the Entire conetence of the Project folder to my work computer. Which has Office 2003. Do I need to recreate the form with the Excel 11 reference. I could not get the form to work on work computer. IT has a com error. I am acessing the EXE for the debug folder w/in the Bin Folder.

The problem in the EXE program is theat I can't draw/view graphics in the picturebox..I coppied my whole program to a new VB project, but I'm having the same problem...In the original project, where the program works, there are no warnings or errors.
View 3 RepliesI created a windows form application using Visual Basic Express Edition 2008 but I did not know I could not use it on the web, which is what I wanted but being new to VB I just got a lot of headaches trying to figure this out. It works fine as a windows app but now just recently I installed Visual Web Developer 2005 to so I could create a web application from the windows app.
It is a simple windows application of a datagrid but now I want to run the same design application I made in Visual Basic to Visual Web Developer Express 2005. Is this possible? And, what do I need to do? I have all of the associated files in my project folder in Visual Basic Express folder.
how does look-up work in Visual Basic, I have done research on this but it does not explain. I have a Form1 called( Booking form) with 2 ComboBox's and 1 TextBox. each called (Destination_FromComboBox) and (Destination_ToComboBox) and (FareTextBox)and another form2 called (Fares Form) with 3 TextBox's each called TextBox1 (FromTextBox), TextBox2 (ToTextBox2), TextBox3(FareTextBox).So when I select (Booking Form) and Insert or select a Destination from (Destination_FromComboBox) and Insert or select a Destination To (Destination_ToComboBox) I want to read from (Fare Form/Fare Table) and give me the fare in FareTextBox on the Booking Form. Also on the booking I have 3 Radio Buttons
(RadioButton1 = 4 Seater Car, Normal Fare)
(RadioButton2 = 6 Seater Car, Time & HalfFare)
(RadioButton3 = 8 Seater Car, Double Fare)
But there is also a time Issue as well:
If the time is Between 05:00 & 23:59 then normal time should be used
If the time is Between 00:00 & 02:00 then time & half should be used
If the time is Between 02:00 & 05:00 then Double time should be used
I have watched loads of video's and looked through forums and other codes for the combination of the above, without success?
I have this great way to use VB6 I treated my project like a .exe file.Say I want to work on c:work directory.I just save as the .vbp file to c:work directory
All the other files (.frm,.bas,.cls) files are in a special directory called library ALL of my .vbp files, in c:work1, c:work2, c:work3 refer to that one same directory.How can I do that in vb.net?
Why this is important? Bugs always happen all the time. If I just run .exe file, when bug happen, I cannot do a thing. However, if I run the project file and run the program in debug mode, when bug happen I can figure out what happen.
