Have The IDE To Create The Event Signature For Under .net?
Jul 14, 2011
for the past >8 years i was doing VB / VB.Net work now I'm jumping into C# world, so far it's very easy only thing that I find difficult is the fact that the signature of every events on object are not automatically created for me.I'm used to select the object name in the left dropdown in the code view and then the event that I want in the right dropdown.is there something similar to that in C#? if yes where can i find it, I really wish I don't have to write them by hand...

I would like to do something like the following:
Public Class Form1
Public Event Evt1(ByVal c As c1)
Public Event Evt2(ByVal c As c2)
[code]...
However, it seems to be invalid syntax, as the signature of OnEvt1OrEvt2 doesn't match that of Evt2.
Edit: The above code seems to work fine for everyone but me, but it doesn't compile for me in VS2005 SP1.The error message is something like:Error BC31029: The method 'Private Sub OnEvt1OrEvt2(c As WindowsApplication1.c1)' can not handle the event 'Public Event Evt2(c As WindowsApplication1.c2)' because the signatures do not match.

I fully realize that what I am proposing does not follow the .NET guidelines, and, therefore, is probably a poor idea for this reason alone. However, I would like to consider this from two possible perspectives:
(1) Should I consider using this for my own development work, which is 100% for internal purposes.
(2) Is this a concept that the framework designers could consider changing or updating?
I am thinking about using an event signature that utilizes a strong typed 'sender', instead of typing it as 'object', which is the current .NET design pattern. That is, instead of using a standard event signature that looks like this:

I'm using a third party grid control which I took and inherited to create some custom properties and events to it. Now when I tried to use this custom control on one of my forms one of the Events that I try to use keeps giving me an error and saying that the signature of the event does not match. It's only for this particular event and it doesn't give me the problem on every form I use this control on. To fix the problem, I constantly have to clean/rebuild the project with the custom grid control and then clean/build the project using the grid control. I'm using VS 2005 and the grid control I'm using is called iGrid.NET made by a company called 10Tec.
The exact error I get is below.
Method 'Private Sub iGridFlightInfo_BeforeCommitEdit(sender As Object, e As TenTec.Windows.iGridLib.iGBeforeCommitEditEventArgs)' cannot handle Event 'Public Event BeforeCommitEdit(sender As Object, e As TenTec.Windows.iGridLib.iGBeforeCommitEditEventArgs)' because they do not have the same signature.

I'm planning on using the Smart Device Framework 2.3 to use the signature control panel in a Windows Mobile 5 application using the compact framework 3.5.
The control has the option to save the signature as either a byte array of points, or as a bitmap. Now seeing as I want to store the signature in a sql compact database, I guess the byte array is going to be better. The trouble is, I'm not sure how to render that in a full WinForms application after I've transferred it back to the desktop.
I need to show the signature on a report, so it would need to be an image I could link/embed into the report.

I've tried everything here, but the Amazon Load Balancer API just will not accept my signature.
Whatever I try, I get a "403 SignatureDoesNotMatch" response. I'm probably missing something obvious, but having spent hours trying to figure out what that is, I'm at the end of my tether.
Here's my code:
Public Sub DeregisterInstanceFromLoadBalance(ByVal strServerID As String)
Dim strURL As String
strURL = "http://elasticloadbalancing.amazonaws.com/?"

I try to run my Authenticode signed app on a clean Vista PC (not internet connection available ever). I have a look in Internet Explorer if the root certificate (Trustcenter) is there, and it is not. I get the message that the reference could not be resolved, and when I click file properties and have a look at the certificate, it says "The certificate for the signature could not be confirmed". Is that a normal behaviour? I mean does the computer need to have the root certificate from Trustcenter installed?

if you are a constant answerer here on msdn, and do not have a unique signature, or no signature at all, please take a little time to create one... eason ..when quoting a post of a member, if no signature available, then it would have to be followed w/ "quoted from so and so's post", this so so said this, etc.

IN VB.NET (not c#)I want to create an event than can be canceled by the listener. Just like you can cancel the closing event of a winforms form in which case the form won't close.I have already implemented a derived class from EventArgs that has a settable Cancel property as follows:
Public Class AnnounceNavigateEventArgs
Inherits EventArgs
Private _cancel As Boolean = False
[Code]...
The listener I have setup is setting the property to Cancel=True. I thought ByRef meant that both _cancel and cancel would point to the same location on the stack and that setting _cancel=true would therefore make the cancel = true. But this is not the behavior I am getting. _cancel becomes true in the setter but I guess the argument to the constructor remains false.

I am using the folowing logic to create an event that can be canceled...
Code:
Public Class ParentClass
Private WithEvents MySubClass As New SubClass
Public Sub DoSomething()
[Code].....
It is my opinion that if you needed multiple things to happen either you would implement some coordination between your event handlers as to who chould cancel when, or have one handler that calls the multiple methods and decides the cancel in one place?

I am working on a project where I have a signature displayed on the screen that is drawn via code based on data that has been transmitted from another device. This is from one of the samples from MS. The signature displays on screen just fine but I need to convert this to a bmp or jpg so I can save it to disk and/or print it on a report.
Code:
PrivateSub DrawSignature(ByVal g As Graphics)
' background
g.Clear(Color.Cornsilk)
' border
g.DrawRectangle(Pens.Gray, 0, 0, pictSignature.Width - 1, pictSignature.Height - 1)
' return if don't have a signature
[Code] .....
I have tried creating a new bitmap from the image property of pictSignature but it is empty even though it has an image displayed on screen. This is the first time I have tried to work with this type of coding and am totally at a loss as to what I need to do to get a bitmap from the data.
