Adding Namespace Attribute To XElement - Prevent Blank/empty Namespace On Child Elements?

Mar 17, 2011

I need to read an xml document from a database record into an XDocument object in order for it to be deserialized. So that the deserialization will work, I need to apply a specific namespace to each of the level 1 elements. So XML looks a bit like this:

[Code]...

How do I prevent the blank/empty namespace being added to each child element of the element to which the required namespace has been applied?

System Namespace Conflict With Sibling Namespace

Nov 16, 2011

This class is located in the namespace Acme.Infrastructure.Interface.A class with the same name EventArgs exists in the System namespace.In another project in my solution I have a class Acme.BusinessModules.MyModule.MyClass.When attempting to use the EventArgs class I have to fully qualify the class name or the compiler thinks I am using the System.EventArgs class.My understanding of namespace resolution was that the compiler would first look for the class in the current namespace, and then its parents. It seems that the compiler checks in System before it checks in sibling namespaces. Is it correct that System is checked before the sibling? Or is this behaviour caused by other issues (Imports order?)?

.net - Application "AppName" Is Inventing The Lower-case Namespace "appname", Causing The "AppName" Namespace To Become Ambiguous

Feb 3, 2011

As I say, I've got an application which I'll refer to as "AppName" (note the upper case 'A' and 'N') which, for example, attempts to reference "My.Application.Info.ProductName". Adding a breakpoint and putting a QuickWatch on that call shows the error:

.net - Does C# Have A Handles Keyword

May 25, 2011

Protected Sub Menu1_MenuItemClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.MenuEventArgs) Handles Menu1.MenuItemClick
End Sub

In VB.net, we have the Handles keyword, I'm wondering if C# has anything comparable. Or do you have to manually wire all the methods to each control's event (in ASP.NET especially)?

Extended With-keyword In .NET?

Oct 29, 2010

In my current project everyone names variables and methods after what they are and what they do. This is good for quickly understanding the code, but with a lot of long varible names comes some headaches, such as when copying a dataset to an entity/object. So, while you understand the code, the readability still takes a blow.

veryLongVariableName.Id = datasetVeryLongVariableName.Id
veryLongVariablename.Something = datasetVeryLongVariableName.Something
etc.

Using VB.NET's With keyword can help.

With veryLongVariableName
.Id = datasetVeryLongVariableName.Id
.Something = datasetVeryLongVariableName.Something
End With

Now, my question, is there any way of using With, or something similar, but for several variables at the same time? Something like:

With veryLongVariableName As a, datasetVeryLongVariableName as b
a.Id = b.Id
a.Something = b.Something
End With

I'm all for descriptive naming conventions, but they do tend to clutter things. Especially in VB!

Use Call Keyword In VB / VBA?

Apr 4, 2010

I use the Call keyword when calling subs in VB/VBA. I know it's optional, but is it better to use it or leave it off? I've always thought it was more explicit, but maybe it's just noise. Also, I read this on another forum: Using the Call keyword is faster because it knows that it is not going to return any values, so it doesn't need to set up any stackspace to make room for the return value.

Aug 26, 2011

I'm still new in VB.net development environment, i've few of the question may need the advice from you guys to see whether i'm in the right track for the development as below condition:Basically my program wrote from this logics:

Condition:

2 log files available in C drive that is C:/BSKYB/Prod.txt

and C:/BSKYB_CWE/many of log files in .txt format

Program Flow:

Step 1: The program will read the last sentence Hexa number from the file "Prod.txt"

Step 2: Once the program detecting the keyword like example "abcde" it will go to another folder which is descript in C:/BSKYB_CWE to look at which text files contains the keyword "abcde"

Step 3: this step will capture the whole line the text info like example 1111 abcde

if in this case, once the abcde detected what is the command i should apply to capture the key word 1111 ?

This is the problem i have encounter right now, i doesn't know how is actually can apply the right method to read the whole text line once the key word is detected

Public Class Form1
' Const ConstBSKYB = "C:BSKYB_CWE.txt "
'Const ConstBSKYBP = "C:BSKYBProd.txt"[code].....

Getting The 'topmost' Keyword To Work

Feb 4, 2012

I am aware of the 'topmost' keyword in VB.NET for specifying a window to be brought to the front or top of the display windows showing. However, specifying 'xlApp.topmost' is resulting in a compile error in my VB 2010 Express project; most likely because my project doesn't include a reference that it needs for 'xlApp.topmost' to start working. What reference do I need to add?

How To Achieve The C# 'as' Keyword For Value Types

Apr 14, 2009

Most of our development is done in vb.net (not my choice) and one frequently used code pattern uses an 'On Error GoTo' followed by a 'Resume Next' so that all database fields can be read with a DirectCast() and any DBNull values are just ignored.

The current code would be
On Error GoTo error_code
oObject.Name = DirectCast(oReader.Item("Name"), String)
