Events Not Working With After Deserialization?

Sep 27, 2010

I have a Child class which uses DataContractSerialization and raises a Changed event when its Name property is set.

<DataContract()>
Public Class Child
Public Event Changed()



The Parent class is serialzed and deserialized and all the data (including the Child) is saved and resored as expected.However, after deserialization, the Changed event is never raised!I know the deserialization process bypasses class constructors, but shouldn't the event be initialized?Is it possible to serialize/deserialize the Event?Is there a way to initialize the event in the OnDeserialzed method of the Child rather than the Parent (see below)?

(1) Add a constructor to the Child class which takes an instance of itself as an argument.

(2) Add an OnDeserialized method to the Parent class which creates a New instance of the Child class based on the deserialzed instance of the Child class.

<OnDeserialized()>
Private Sub OnDeserializedMethod(ByVal Context As StreamingContext)
Child = New Child(Child)
End Sub

Now the Changed event is raised as expected.

Apr 21, 2010

I have the following classes: Public Class Email

[Code]...

If a create a wrong email lets say "email" the exception is correctly cached and a message is showed however is i input a valid email the event is not raised, the object is being created but no message is shown and no error or exception is thrown i suspect it has something to do with using "myemail = new Email(email)" but i have seen examples of using new with withevents with no problem.

Working With Mouse Events?

Jun 23, 2009

I am working on a project which will be installed in Embedded pc which won't have mouse and keyboard. Works with touch screen. I have an option in my software to make calls.I need to have an option like Push to talk. When need to talk they need to push the button and when they release they can't talk. Something like walkie talkie concept. The embedded pc where my software will be installed will have touch screen. How can I do this??

VS 2008 : Use The Keydown/keyup Events With Buttons In The Same Project And It Not Working Properly?

May 12, 2009

I am trying to use the keydown/keyup events with buttons in the same project and it not working properly. I have 4 red boxes and when I press an arrow key the box should change to green according to which arrow key it corrosponds to. I have this part working fine, however only when there is nothing else in the project. When I add in say 3 buttons, Button1, Button2, Button3 and try runing the program instead of the correct red box changing to green, button outline just moves between buttons 1,2 and 3. I have tried turning tabstop off for the three buttons but that didnt work. how to read the keydown/keyup while still having buttions that can be pressed with a mouse?

XML Deserialization Not Setting Class Values

Nov 25, 2009

I am not seeing what I am doing wrong. To see what was being done, I changed the constructor values to "TEST", after the XML gets read in (I verified what the XML is), the class values are still stuck to "TEST". Any more Ideas? I am doing this process already in another class that works fine, neither me nor some co-workers could find the difference.[code]...

Binary Stream '0' Does Not Contain A Valid BinaryHeader When Performing A Deserialization From Memorystream

Jul 18, 2009

I am trying a simple object deserialization from an object encoded as a Base64 string, but I keep getting this weird error message. I've searched the forums for a solution but those who've experienced this all had different reasons for the error. The most logical solution, which is resetting the stream's position, did not work either. Here's my code:

Dim UnserializedObject As Object
Dim ser As New System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
Dim buffer As Byte()

Incomplete Binary Deserialization - Message Box Only Displays First Entry Into File And No Other

Jun 24, 2010

To object oriented programming and programming with visual basic .net (vb 2008 express). regarding storing of information but not in a database. Someone mentioned using binary or xml serialization. So I researched that and after two long 8 hour days of messing around with binary serialization and about a dozen different code techniques i finally found one that seems to work. I created a module that serializes two variables and appends them into a file. The same module also has a sub that deserializes the information from the file and displays in a message box. If needed I'll provide the code later.

Really the problem I am having is that my message box only displays the first entry into the file and no other. So I can append any number of variables to the file but every time I call the subroutine in my module it only displays the first entry. How do you read all of the file? Also can I search the file for a particular value of a variable? The variables are codependent. The two variables are simply a date and a string representing a changing code that corresponds to that specific date. So I'd like to be able to say search for a date and retrieve both the date and the code.

However I don't have any idea how to do this. Also the messagebox.show method is probably not the best way to illustrate the information in the file but I'm still new and I'm not sure the best way to show all the info in the file. For instance if I wanted to show the entire contents or just the codes corresponding to certain dates. I know a database is probably the better answer but I've gotten this far without one, lol, I'm too stubborn to change now. Once I figure this out, I'll switch and try the same technique with a database.

Mouse Events And User Control - Control Won't Respond To The Events

I created a control that has picture box control docked within it. This control allows me to "animate" the image by swapping them out by setting the interval to swap them at. I want to use this control kind of like an animated icon within a application, but because the picture box is docked, the control I created won't respond to the events, MouseHover specifically.

VS 2008 Cannot Seem To Get A Working Filter In Working Order

Jun 18, 2009

It appears that my favorite thing in the world is tackling projects that are beyond my current knowledge and abilities. I have a little project that I am working on which is a simple image viewer stocked with (upon completion) your standard Load..., Next/Previous, Zoom In/Out, Actual Size, and Full Screen capabilities. However, I am running into a few snags:

(1) I've been able to get my "Load..." button to display a file dialog box, but I cannot seem to get a working filter (with which only image file types are allowed to be selected) in working order.

(2) I have a PictureBox object (entitled PictureBox1) that displays the image selected via the file dialog box, but it loads images in their full size (1:1/100% zoomed) state without scrollbars, etc. to allow me to navigate the loaded image. I would like to have it load the image, initially, to fit within the dimensions of PictureBox1 and from there be able to zoom in/out via my "Zoom In/Out" and "Actual Size" buttons and be able to scroll if the zoom level is beyond the dimensions of PictureBox1.

(3) It dawned on me that I haven't the faintest idea how to get my "Next/Previous" buttons to allow the user (me) to navigate, in succession, the images contained in the folder in which the currently loaded image is stored. [code]

If it is deemed that this thread is inappropriately requesting help, I ask that it be locked/deleted quickly as I recognize that this is a large community with many discussions going without need of unwelcome posts.

Private Sub SUB_handles_something_changed() Handles Me.EVENT_something_changed

no errors with this code, but how is Me possible since the Event is shared. it seems like there's no errors between switching shared with un-shared and switching Me with Myclass, all 4 combinations seem to work, isn't that weird

.net - Events In Classes?

Jun 17, 2010

I find that I write a lot of code within my classes to keep properties in sync with each other. I've read about Events in Classes, but have not been able to wrap my head around how to make them work for what I'm looking for.For example, in this one I always want to keep myColor up to date with any change whatsoever in any or all of the Red, Green or Blue properties.

Class myColors
Private Property Red As Byte
Private Property Green As Byte

[code]....

If one or more of those changes, I want myColor to be updated. Easy enough as above, but is there a way to work with events that would automatically do this so I don't have to put myColor = Color.FromArgb(Red, Green, Blue) in every sub routine?
