Why Does Changing Solution Platforms Stop Partial Classes From Being Seen
Nov 18, 2010
There is an older version of the software which works fine on all of our deployment platforms, but the version I am trying to push out is working fine on 32-bit desktop installations, but is crashing-and-burning when it attempts to access Crystal Reports and Informix installed DLLs on a 64-bit machine, running terminal server sessions (yeah, I know, could I change anything more about the deployment platform?)One of the suggested avenues of investigation was changing the solution platform from "Any CPU" to x86.On attempting to do this, Visual Studio seems to stop being able to connect the partial classes constructed by XAML objects, with objects declaring that they have no "InitializeComponent" methods, and then failing on down the line until I reach the maximum number of errors.
Oddly, changing the solution platform, and then rebuilding in Expression Blend compiles just fine. Changing the platform back to AnyCPU makes the problem disappear. All projects have compile and debug configurations set to Active. I can't see any reason why simply changing the targeted platform would stop the XAML from generating partial classes Okay, it seems to be that there are some external DLLs to the project, and that those are the cause of what I'd call the first-level compilation failure, as they don't seem to contain any classes once the target platform has switched.In VS2008, this causes the cascading failure of absolutely nothing working at all, as described above, but at one point I somehow managed to import the project to VS2010 with only those errors in place (missing classes, etc.), without the rest of the project imploding.I'm now working on reconstructing those classes from those DLLs, and hopefully will be able to get together a project that will compile on multiple target platforms by the end of the day.
I see two options in my "Active solution platforms":
.NET
Any cpu
What's the difference? Which one would I want to use for debugging? I see folks used to ask about "Mixed platforms" vs "any cpu", but I don't have "Mixed platforms," I guess it was removed in 2010.
Would "Any cpu" be compiled to binary, while .NET be compiled to MSIL?
I have the follow VB.NET class definition:<Serializable()> Partial Public Class Customers End Class
Inside another file I have the same thing (with different methods and variables of course). When I compile, I get the following error:Attribute 'SerializableAttribute' cannot be applied multiple times.The error is pretty self explanatory. My question is though, if I just mark the one class as Serializable(), can I assume the entire class with be marked as serializable()? In other words, Do I only need the serializable() tag in 1 spot in the class?
We have a big Form class that we like to split into peaces using partial class approach That could be done by manually modifying a project file, and adding MainFormPN.vb entry
The issue with this approach is when double click on this item in VS2008 IDE it shows new empty form, not MainForm UI. It looks like VS2008 does not support multiple partial classes for a Forms.
I'm still learning so this might be completely wrong. I have built a multi-user web application for internal purposes. I have split my code up to make it more manageable and have run into some problems. I suspect that I have done something very silly!
I have a class in a separate file (quoteStatus.vb) in App_Code here it is:
Imports Microsoft.VisualBasic Imports System.Data.SqlClient Imports System.Data Public Class quoteStatusHelper
[Code]...
This seems really wrong, as the value seems to be held in the partial class after the first run. So if I have two users accessing the class the public shared dim is changed for both users! There must be a better way to do this. I have looked everywhere and I'm more confused now than when I started off..How can I make QuoteStatus in the partial class unique to every user and access it from my code.
I'm writing a WCF-Service and I split up my service class to multiple partial class files, so every ServiceContract-Implementation gets its own file. I have one file however that should contain e.g. members that are used by every partial class file such as a logger. The service is hosted with IIS 7 if this matters in any way.
[Code]....
The code compiles fine, but at runtime I get an BC30451: The name m_Log is not declared Error (Don't know the exact words for it. I get a german message ;) ). I don't think it has something to do with the type of m_Log or a depending assembly because I get the same error if i try this with a String. What am I doing wrong? How can I make this work? Edit: I was trying the same thing in a simple console application without any problems. :(
We are using T4 to generate our .aspx and .vb files. Everything works well - but we often have to customize behavior on the pages. However, we also occasionally have to regenerate pages - which has the potential to wipe out work which would otherwise still be valid. I would like a setup like this:
Default.aspx 'which would contain the controls Default.aspx.vb 'which would bind, load and save data Default.behaviour.vb '(or something like that) - which would store the behavior
With both the pages being able to reference the controls. Is that at all possible? [Code]
In my never ending search for more knowledge, I have come across Partial Classes. I was wondering if some of the kind people who actually understand the uses could explain some of them to me. Now I know that when we create a form that we actually create a partial class which the generator rewrites when we add a control or change a property at design-time, and this allows us not to have to worry about setting up the controls ourselves.
Currently, I have a solution that contains two projects (ASP.net websites, FWIW). If I create a class in Project1, how do I expose it to Project2? Is it automatically available to Project2 because they are in the same solution? Or do I need to do something special to make the connection?
My immediate issue is that currently I have a 3 tier solution (Presentation.aspx.vb calls BusinessLayer.vb which calls DataAccessLayer.vb). However, I want to make BusinessLayer and DataAccessLayer.vb abstract classes because several Webforms will use have the same functionality.
So I currently am doing this (no abstract classes):
'Presentation Layer (pseudocode) public sub checkUser(byval userName as string, byval dept as string) dim isGood as boolean = BL.checkUserAccess(userName, dept)
hello,if i have a solution with two projects, and add a class at the Solution-level, how do i reference that solution-level class within one of the two projects?
I am having this strange thing happen where I have a Module that contains multiple classes in my project. In the Solution Explorer, the module shows up as a Windows Form and if I double click on it to open it, it tries to open the Form Designer. What could be causing VS to think that it is a Windows Form instead of a module?
I am on my second project. I made the mistake of trying to use my first project as a template thinking there was a 'Save All As...' which I found there wasn't.
I went through the whole project and now it is forcing me to use the folder names that everything is saved in from my first project and my professor wants the directories named a certain way.
If I try and change the names of the folders, then upon re-opening my solution I get errors because the directory has changed.
Is there a way for me to change the directory names and not have my program fall apart? Or re-direct it where to look after I change the folder names?
I have a large web app in vb.net 4.0. Its default namespace is configured in its project properties. None of the root-level classes in our app are surrounded by namespace declarations. When I add a .asmx file to the root folder of the website, it compiles fine, but it doesn't work for some reason (already asked why in other topics). So to get it to work, I try to surround the class declared in the .asmx by a namespace declaration. As soon as I do this, I go from zero compiler errors to about a zillion. My app can't find ANYTHING in the root namespace. But I haven't changed any other files, only this .asmx file.
WHY is it behaving this way? How do I prevent it from behaving this way without refactoring the entire app? I would love to blank out the default namespace and add them explicitly around every root-level class, but I'm not sure that would fly with our release manager, and I don't even know if it would fix the problem.
The following procedures sorts a listview column based on what the tag is, 'Numeric', 'String' or 'Date'. When you click on the column header the sort procedure kicks in. On the first click it will sort ascending and on the second click it will sort descending.
My problem is that when I click a second time it won't sort descending but re-sorts ascending again.It appears when the sortorder is passed to the ListViewColumnSorter.vb classes it changes back to ascending even though it's called as descending. I've bolded the offending variables using a Numeric search.Now here's the really iritaing thing, I have exactly the same code in another application and it works perfectly?
Private Sub lvwResults_ColumnClick(ByVal sender As Object, ByVal e As System.Windows.Forms.ColumnClickEventArgs) Handles lvwResults.ColumnClick SortMyListView(Me.lvwResults, e.Column, , True)
I am writing web services with VB.NET (2.0). The client side will use different technologies such as Java and Siebel. So, if I write asynchronous web services, is it possible for different platforms to consume them? I know it is quite easy with a consumer having .NET platform, but not sure for different platforms. Is it enough for them to have asynchronous ability, or should it be a similar platform?
is there an easy way to stop the changing of colours when you disable a control. i want the controls to look normal just not do anything if you try to use them would have thought there is a global setting or something??
I created 3 web browsers (the web browsers is not visible) thet refresh themselves all 2 secondsbut now the cursor change to "AppString" and return to "default"now In every 2 seconds it happening again.
Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load If My.Settings.registered = True Then Form3.Show()
[code]....
This is my code for a trial application. The code is pretty basic but what i couldn't figure out was how i would be able to prevent users from changing the date to extend the trial ("error" i would be getting).
I am generating an array of random numbers for for a class project (simple yahtzee game)I am comparing the output of the array and displaying a picture of each matching dice in a picture box.I would like to use check boxes to select a position of the array so it cannot be changed until the check boxes are clearedWhen the check box is checked, the value of the position in the array should not change.
I have extended an Entity Framework 4 entity class with a calculated property in a partial class. This member is not available on the client to which the entities are exposed via WCF RIA Services.when using C# appears to be changing the extension of the partial class file from .cs to .shared.cs. I tried this with my VB.Net solution (.vb to .shared.vb) and got a long list of errors. I believe what happened is that the partial class lost its association with the entity on the client - it inherited from object rather than EntityObject.
My best guess is that this is related to the way that VB.Net handles namespaces.Each project has a 'Root Namespace' which is prepended to anything that is defined within a code file. C# has a 'Default Namespace'which is the namespace into which new types are placed by default - via a namespace statement within the file.The partial class is probably having the client namespace prepended to it which puts it into a different namespace than the entity with which it is associated on the server.Is there any means of extending an entity in such a way that those extensions are available on the client via WCF RIA Services and VB.Net?
I have two classes, one nested in the other. [code]Neither "Name" or "ID" are unique between operations and records.I wish to construct a dictionary using LINQ = Dictionary(Of String, Of List(Of Integer), whereby the keys are uniqe examples of Names in my collection and the values are the collective set of distinct IDs that are associated with those names.
How can I structure my classes so that the user interfaces though a single class while the supporting classes are hidden from their view? I think its best understood in an example:
Public Class MyInterface Public Economic as EconomicClass Public Sub New() MyBase.New()
[code].....
So you might ask why am I even separating them? It's strictly for others who will be working with this interface. I need to funnel them though a logical structure:
This way everything is already handled for them in the background and they only need to run the method they need. I don't know if I can have it both ways in VB.NET.
Alright, so I'm still working on the slot machine. I have three timers all independently going for my three "wheels" of the slot machine.
My issue, is that I'm trying to make a Stop button to stop each timer one at a time, and I'm not understanding why this code isn't working. The logic completely makes sense, and the first "wheel" stops when I click the button, however, it doesnt appear to stop the other two timers.
