WPF - Set Binding In Object Initializer Expression

Aug 14, 2011

For adding some images to a WrapPanel, I'm trying to iterate through a collection. My TileCollection contains instances of a Tile class which has a ImageSource property. I've got it by doing all the stuff step by step - Create a new image 1, assign all the properties, create a bew binding 1, assign binding 1 to image 1, add image 1 to the panel, proceed with image 2, ... tons of code I want to shorten now. Here is what I've got so far:

For Each tile As Tile In TileCollection
MainPanel.Children.Add(New Image With {.Width = 80, .Height = 80, .Margin = New Thickness(10), .SetBinding = New Binding With {.Source = tile, Path = New PropertyPath("ImageSource"), .Mode = BindingMode.Default, .UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged)}})
Next

1) ."SetBinding" doesn't work in object initializer expression. Is there any workaround?
2) Is there any way to add a handler in object initializer expression, for e.g. capturing mousedown events?

Error: The Type Initializer For 'HG520b.MHProgramming' Threw An Exception

Jun 22, 2012

I've been writing an application, and all has been going smoothly; I tried to debug my application, after many previous debugging sessions and from nowhere, I received an error. I've not changed the module in which the error is coming from, but I can't narrow the error down either.

Here's the error: The type initializer for 'HG520b.MHProgramming' threw an exception.

This occurs any time I attempt to debug my application and linked to a function, property or enum which resides in my module.I don't know where to start looking for this error seen as it's all random...

VS 2008 - Error With Arraylist In My.Settings - Object Reference Not Set To An Instance Of An Object

Object reference not set to an instance of an object.

I'm not really sure what I'm supposed to be doing with this. It's a new setting I just added and it's empty, so I'm not sure if that has anything to do with it or not. Anyone know what's going on and what needs to be done to get it to accept a value and not want to be "initialized"?

VS 2008 Error - System.NullReferenceException: Object Reference Not Sent To An Instance Of An Object

Oct 23, 2009

I have recently gotten my hands on a free, open-source IMAP connection API.So far, I have been successful in creating a connection to one of my accounts.Where I'm getting stuck is retrieving folders and/or emails from those folders.Does there happen to be anyone here that is familiar with this API, or even Gmail (particularly the folder structure for IMAP)?

If not, here is a link to the DLL that is listed on sourceforge and the company's website that created it (if you feel like testing):

Koolwired
Sourceforge - Koolwired API

I have created a test account so feel free to use the code below without worrying about username/password issues; I'll just delete it when I'm done with it.Here is the code I have made so far for making a connection:

Dim gSession As New Koolwired.Imap.ImapConnect("imap.gmail.com", 993, True)
Dim gAuthenticate As New Koolwired.Imap.ImapAuthenticate(gSession, "imap_test@serysoft.com", "imap_test")
Try

[code]....

When I run that code, I get an error that states:System.NullReferenceException: Object reference not sent to an instance of an object. (The bold line in the above code).

Now, I'm not sure exactly what that means. Does that mean it tried to access the server and "INBOX" doesn't exist so it gets returned a NULL value? Or is it possibly the coding itself?Maybe the Gmail folder system is weird due to the fact they use labels (even though from what I have read online, the labels act as the folders in the IMAP system).

CODE:

I am trying to get information to be pulled out of a database and show in text boxes on another form (frmviewsdets). The error occurs when it gets to the line frmviewsdets.txtsnumber.Text = rdr("StudentNumber") and even when a breakpoint is applied there it just moves on to the next and so on.

I have tried to show frmviewsdets before I pull the data out of the database beut I get the same message.

Error - NullReferenceException Was Unhandled - Object Reference Not Set To An Instance Of An Object

Apr 15, 2009

I'm finishing up working on the high score list of my Jeopardy game. The only problem that I'm running into is when I try to start from scratch without a textfile in the Debug folder.I get a NullReferenceException was unhandled - Object reference not set to an instance of an object. I get this message with the line If (myPlayers.Length - 1) > 2 Then just before I start to compare the scores and reorder the list by score if necessary.I already declared myPlayers as an array of structures in the beginning of the form.

Private myPlayers() As Players

It writes the name and score to the file, but then gives me that error. My goal is to only fill the file with the three players names and their scores.I figured since the file doesn't exist, I'm doing something in that specific code that effects my reference to myPlayers but I can't figure out what exactly. I tried adding

If (myPlayers.Length - 1) > 2 AND File.Exists("highScore.txt") Then

but its still giving me the error.

'read in scores, add scores to file or create new file if neccessary
If File.Exists("highScore.txt") Then
Dim InputFile As StreamReader

Error : Unable To Cast Object Of Type 'Object' To 'CTest'

Feb 22, 2012

I have

Public stack() As CTest

I want

Public stack() As Object

The latter is giving the error "Unable to cast object of type 'Object' to 'CTest'." when used:

Dim thestack As CTest() = testdatabase.getStack
Where testdatabase.getStack simply returns stack();
Public Function getStack() As Object()
Return stack
End Function

This fixes it, but it's not ideal (for me personally):

Dim thestack As Object() = testdatabase.getStack

So if I could keep the variable as-is (Public stack() As Object) and then do something along the lines of class.stack() = CTest I should be able to do Dim thestack As CTest() = testdatabase.getStack because the object array will programmatically have changed from Object to CTest.
