Workaround For Partial Method Using CodeDom?
Nov 30, 2009I know CodeDom doesn't support partial methods, but is there a workaround? I found a workaround for C#, but I need one for VB.NET.

Passing DataSet To A Method Using CodeDOM?
Jun 17, 2010In my main application i am trying to run Pre-defined Code blocks that the user has created. I would also like to send a DataSet as a parameter when the code is compiled. Is this possible. Currently I can pass in single values by assigning them as a string in the code wrapper through the <%= input %> expression. Then i compile this as source.

C# - Test For A Renamed Partial Method?
Jun 30, 2011I'm using Linq to SQL, which generates partial classes and partial methods. You then extend that generated code by implementing your your customizations manually in another partial class. One of the hooks L2S gives you is the ability to implement partial methods that get called when a property changes. For example, if you have a property named "MyProp", then you can implement a partial method like so:

Partial Entity Class With Shared Extension Not Associated With 'other' Partial Class In Client Using RIA Services?
Apr 21, 2011I 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?

What Is The Equivalent Or Workaround For A Typedef
Dec 22, 2011I am coding a VB.NET application which heavily deals with a collection type. See the code below:
[Code]....
I have to type the above line for so many times. If I changed the collection type, then I have to make the change for all the instances. So if there is a way to use "a typedef equivalent", then I can get rid of all these problems. I tried with imports, but it is only for namespaces and it can't be used for classes.
Note: I am using VB 2008, windows XP. The application type is windows forms(VB). EDIT: I made some tries based on code_gray's below answer. This is the first try.

.net - Workaround - ByRef Parameter Of A Property
Mar 19, 2009I have a legacy COM-component with an interface declaring a property like this (IDL notation):

This interface is implemented in a calling application written in VB6 like this:
[Code]...
Everyting works fine until I try to do the same in VB.Net. VB.Net refuses to compile code where a parameter of a property is passed ByRef. MSDN says VB.Net doesn't allow such parameters. Is there any way I could implement such a property in VB.Net?
ASP.NET: Httpwebrequest Date Header Workaround?
Jul 16, 2009I'm trying to integrate with an API that requires the "Date" header in a web request. As you may well know, .NET has removed the ability to append or even display a default Date header in your request, so I was wondering about a workaround.Here's the catch: you can't use TCPClients because I don't have "permissions" on my server for such a thing as sockets. Is there some way to "cheat" the system to fake a date header or to trick it into posting a Date header? Or should I just give up on this API?

Design Mode Preprocessor Directive Workaround?
Jul 12, 2011I know that there is no DESIGN, DESIGN_MODE, DESIGN_TIME, etc preprocessor directive value. However, I need something that can do the trick. I can't use a normal If statement, because in my case I need to change the inherited class so that the control renders properly at design time. If not, I'll receive an exception due to the fact that the inherited class is an abstract class.Here's what I'm looking to accomplish:
Partial Class MyCustomControl
#If DesignMode Then
Inherits UserControl
#Else
Inherits WidgetControl

Large Array = System.OutOfMemoryException Workaround?
Jan 23, 2009I'm downloading a bunch of files from a URI but when they get big, I get an utOfMemoryException. I thought at first it was MemoryStream error but I'm pretty sure now that the error is rooted in the declaration of an array of Bytes that's too large. (Half a gig is fine, 1.7 gig is not.)
View 1 RepliesIs This Workaround/architecture Correct Using Classes (complex Properties)?
Feb 15, 2012what's a Class, and Object, a Method, a property and thins like that, but I have this doubt:Let's supppose I have a class "Laundry" this class has (just for this example) 3 propierties:
1.- laundryID
2.- Name
3.- Washers
Id and Name are "primitive" types or simple types (integer and string), but Washers, represent a list of object of type "Washer", that has 3 properties:
1.- washerID
2.- laundryID
3.- capacity
4.- brand
All of them (for this example) simple/primitives types (integer,string,string).So this my dilemma, it is correct to have a constructor like this (VB .net)
public sub new(ByVal laundryID as integer)
'' Here I'll query for the data of the Laundry on DB
'' After that I will query for every washer that belongs to this laundry
[code]....
And inside of that constructor query for all the washers that belongs to the laundry with id=laundryID parameter, and create objects of type "Washer" and add them to the list of Laundry ?I'm not sure If I explain myself, any comment I'll be really grateful, in less words, what's the correct approach (or good practices) to work with class/objects that has properties which are complex (other class/objects).I usually work with ADO.net probably ADO/LINQ/Entity solve this thins in an transparent way, but if they do it I don't really know it.
Note: I'm familiar with VB.net, C#, PHP, so if you prefer explain/help me using examples with its syntax, it's ok
VS2005 @ X64 Environment - Workaround To Enable Edit And Continue?

View 2 RepliesWorkaround For Lack Of True Transparency In Labels And Other Controls
May 4, 2011I'm trying to make a label transparent. When I set the BackColor to transparent, all it does it take the color of the form it's sitting on, i.e. It's not truly transparent. I've googled it and found this in another thread (from a MSFT MVP)".NET controls do not support true transparency. You can set their BackColor to Transparent (in some but not all cases) and the parent control will show through, but only the parent control. If there is some other control behind that is not the parent it will not show through. That's because the control is not truly transparent. It basically copies its parent in the area behind it and uses that as its background, but that doesn't include sibling controls that may be behind it as well." To me, this is completely unacceptable. Why even include the transparency option when all it does is set the control's backcolor to the form color? I'm trying to add a label over a progress bar to give my user some feedback (because the Visual Studio progress bar doesn't support text, which is also a horrible design shortfall by the way), and have yet to find a way around this.

View 11 RepliesC# - Codedom And String Handling?
Aug 14, 2010I'm trying to see if Codedom can handle strings and concantination between different languages, without me setting up conditional strings per language.For example, I need to generate the following exactly as shown below in both C# and VB.NET via Codedom:
C#
errorMsg = errorMsg.Replace('"', ''').Replace("

System.Windows.Browser.HtmlPage.Window.Eval("throw new Error("Unhandled Error in Silverlight Application " + errorMsg + "");");

The CodeMethodInvokeExpression for errorMsg.Replace and System.Windows.Browser.HtmlPage.Window.Eval is simple enough, it's the string inside them that I can't figure out if Codedom can automatically handle.

CodeDom To Generate Operator Overload?
Jan 10, 2011Is there a way to use CodeDom to generate an overloaded operator in Vb.net? I want to generate this:
Public Shared Operator =(ByVal x As MyType, ByVal y As MyType) As Boolean
Return x Is y
End Operator
The closest hack I can think of to do this the following:
Dim eq As New CodeMemberMethod()
eq.Name = "Operator ="
eq.Parameters.Add(New CodeParameterDeclarationExpression(New CodeTypeReference("MyType"), "x"))[code]....
Which generates this, close but obviously wrong:
Public Shared Function Operator =(ByVal x As MyType, ByVal y As MyType) As Boolean
Return (x Is y)
End Function
