Winforms - Serialize The Main Class In My VB Solution?
Apr 5, 2011
I'm trying to serialize the main class in my VB solution. I've added the Serializable attribute at the top of my class like so:
[code]...
I'm guessing this is because you can't serialize the form that is attached to the class or something, but I really don't know what I'm doing. Can I serialize all of the objects contained in my Form1 class somehow, without getting this error? I don't want to store any data about the form controls, I just need to save all the objects that I've defined at the top of the Form1 class.
If a class is serialized and has events fired from it that are handled on a form you get the error "Form1 cannot be serialized" in c# you can use (to work around this):
Every Visual Basic application must contain a procedure called Main.
I Didn't find such a method in my solution..
[Code]...
My problem is, in fact, I try to follow a recommendation that says: Clipboard.GetDataObject Always Returns null? If you find you're always getting null from GetDataObject, try adding [STAThread] before your static void Main().So, me, if I don't find Main()... I can't follow that recommendation in VB.NET...
I developed a VB Winforms application in VS2010 Pro on my Win7 x64 desktop computer. I also have VS2010 loaded on my Win7 x64 laptop and when I open the same solution the application's form controls are shifted out of alignment and appear slightly stretched horizontally. The VS IDE settings are identical on both computers. Any idea why the solution looks perfect in the IDE when on my desktop, but when opened in the IDE on my laptop, all the controls shift out of alignment horizontally
I need to look at the properties of an object and I cannot instantiate this object in the proper state on my dev machine. I need my client to run some code on her machine, serialize the object in question to disk and then I can analyze the file.[code]...
I'm interested in building my own basic Application controller and ditching the Application Framework entirely.Never done this before (or even considered it) but now I'd like to be able to cut out anything that stands in the way of making my App compatible with both DotNET and Mono, for which Microsoft.VisualBasic.ApplicationServices is pretty famous.I start, or links to sample Main Modules for WinForms online? Seems like most of what I find is for Console apps.
CustomLineCap does not have the SerializableAttribute applied to it. I want to add a property of this type to an object graph that is currently being serialized/deserialized with a BinaryFormatter. I tried switching to XML serialization but it has a bunch of extra requirements and I don't want to fool with that esp. since it's not my code; it's some open source I downloaded. If there's a way to get BinaryFormatter to ignore the property, that might work. I'd rather subclass it; I just don't know if that will work either.
I am trying to figure out a class/struture to handle the following JSON format:
{ "ReturnData": [ { "id": "msg2DoesNotExistName",
[Code]......
I may or may not have Data for ReturnData and SetValue (one or both at a minimum). I am trying to let the serializer handle most of the formatting without having to check for empty sections and single-item arrays.
I am trying to serialize a class that contains a generic list, and I am finding it all works with the exception of the generic list property. That is to say the other properties are serialized fine and no error is produced.
I have in the past serialized an arraylist - but I thought it was possible to do a generic list in the same way.
Am I missing something or is it not possible to serialize/deserialize a generic list - I have read mixed comments on this..
The relevant parts of the class that gets serialized is defined as..
<XmlInclude(GetType(cConfigUser)), _ Serializable(), XmlRoot(ElementName:="Config")> _ Public Class cConfig
I want to Serialize and Deserialize a configuration class containing a Dictionary to a XML file.Here is an exemple of what the class look like.
Imports Public Class
[code]....
When I try to serialize it with a XmlSerializer I get an exception saying to me that it is impossible to serialise Configuration.Parametres because it implements IDictionary.
I have a issue in a serialization process. I'm trying to Serialize a part of a bigger class.
I've a Class named MyBigClass with contain many property and method, and some of them may not be Serializable.
And I'm trying to Serialize one property of the MyBigClass class, witch is a SortedList named SubClassXList defined as SortedList(Int32, ClassX)
My problem is when it is time to serialize the SortedList (SubClassXList) a error tell me that a Class (say Class B) could not be Serialized because it is not marked as "Serializable", but the Class B in question have nothing to do with the SubClassXList in question.
The only thing I could see, is that the Serialization method try to also Serialize the Main Class (MyBigClass).
Here is the method that I use to Clone a Object ClassX do have the attribute "Serializable()"
Public Function CloneObject(ByVal pObjectToSerialize As Object) As Object ' Create a memory stream and a formatter. Dim ms As New IO.MemoryStream()
I need to be able to serialize a class into a string, and I know of 2 patterns:
1) (normal) Serialization pattern
2) Proxy Serialization pattern
I've read [URL] (the only website in google that talks about the proxy-serialization pattern) and still cant find the advantage or benefit of using this pattern. Could someone explain what exactly is the proxy serialization pattern, or rather exactly what problem does the proxy-serialization pattern solves that the normal-serialization pattern doesn't solve?
Question: I must get the content of all sessions in a HttpModule, under .NET 1.1. (don't ask my why certain people still use it) I can write the module, I can get the sessions. But... sessions are stored as
How best to manage multiple dat files for serializable objects of the same class. If one of my data files goes past a particular size, I want to create a new file. I then loop through both files when I do processing. Is there any easier way to do this and what's the best size to do this at in terms of performance?
I have added some classes to my project and now i want to define a variable as one of the classes, for example the class is called xml and i want to create a variable called XMLfile and have it as the class XML.
Can this be done? Or can variables only be declared as types (like Integer, string, etc)?If you're not living on the edge, you're taking up too much room
It was suggested that I pose this question here instead of the installation forum:In VB2010, when opening a class, form, etc. from the Solution Explorer, I would like it to open as a floating window, not as a tabbed document. Is there a way to do this?
I'm try to create a class has been create by main class only by protect sub New but how do I create it ?
Public MustInherit Class Rune Protected MustOverride Function Create() As Rune Public Shared Function Factory(Of T As Rune)() As T 'I can't use "T As {Rune, New}" because Sub New isn't Public 'Return (New T).Create End Function End Class
Enviro: 2007 Exchange Server, 2 Intranet servers (1 deploy, 1 dev) running .NET 2.0 app - all within same network / behind firewall. I am working on a legacy app by our previous web guy, when our sysadmin upgraded to exchange 2007 and put it on a new server all of the mail functions in old app broke. Had to upgrade to .NET 2.0 (from 1.x) and nothing worked untill I tried new SMTP code in a local function in the codebehind of a page of the app instead of calling a class, as follows:
Function SendNow(ByVal strFrom As String, ByVal strTo As String, ByVal strSubject As String, ByVal strBody As String) As Object Dim msg As New MailMessage() Dim smtp As SmtpClient
[code]....
So the above works fine, in that file. The problem is that the app was designed to call a class that resides on the dev server. When I move this same code into the class on the dev server I get transport errors. I think this has to do with the fact that we're using integrated authentication with impersonation=true and it seems to get dropped due to the class being on a different server (even though it's behind our firewall).
I could either try moving the classes to the production server or somehow keep the authentication in the class working through the hops. Either way I need to keep the class because it's referenced all over the place (in more than just this app). I am not that savvy in .NET and I cannot figure out where the setting is within the app that defines where the class is imported from. It just seems to be available no matter where the app is deployed. (Working files are on same server as classes, then publish the app to production server).
We have a Dell laptop used to run an in-house VB.NET program. It got a virus. We had to wipe the hard drive and reinstall Windows from scratch. We use Windows XP Pro, which is what was installed on it before. But now our VB program won't run. After trying and despairing of getting remote debugging to work, I actually installed Visual Studio 2005 on the machine, just long enough to get information about what was making the program fail. And the failure was most peculiar. It isn't in our code. It's in the VB setup code that loads the main form. And it says, "Error loading form: class not registered."The gory details are given below. Now here's the strange thing. Not every VB.net program fails on this computer. And the program that fails, fails only on this computer; it has run successfully on several other Windows XP systems with .NET Framework 2.0 installed.[code]
what's the main difference between a Class and a Type and a ValueType.and is a Delegate a Type? or an eventhandler/event (the actual event itself)is every object a type? or is it only true in VB
