IntelliSense In Xml Literals
Sep 2, 2009is there a way to enable IntelliSense for XML literals in VB9 (VS 2008)?The ideal source of IntelliSense is an XSD document, but I can use anything else format to do it.

.net 3.5 - Recursion With XML Literals?
Jul 28, 2009I have a class called Profile that has some simple properties and then it can have a collection of ProfileItem that again has some simple properties and then it can have a collection of ProfileItem (RECURSION). Now I am trying to generated a very simple save function using XML Literals that come with VB.NET (3.5).

LINQ To SQL To XML (using XML Literals In C#)
Oct 2, 2010Is it possible to use variables like <%=person.LastName %> in XML string this way?
XElement letters = new XElement("Letters");
XElement xperson = XElement.Parse("<Table><Row><Cell><Text>
<Segment>Dear <%=person.Title%> <%=person.FirstName%> <%=person.LastName%>,
[Code]....
If it's possible, it would be a lifesaver since I can't use XElement and XAttribute to add the nodes manually. We have multiple templates and they frequently change (edit on the fly).
If this is not doable, can you think of another way so that I can use templates for the XML?

View 13 Replies.net - Working With Byte Literals?
Dec 7, 2009I'm using the following function to brighten up color values (it's a lambda in my code, but that shouldn't make a differende):
Function ReduceDistanceTo255(ByVal i As Byte) As Byte
Return i + (255 - i) 2
End Function
It won't compile, since the compiler interprets 255 and 2 as integers rather than bytes, making the result of type Integer. Unfortunately, there is no Byte type character, so I cannot just write 255B or something like that.There are a few obvious workarounds to the problem:
Function ReduceDistanceTo255(ByVal i As Byte) As Byte
Return i + (CByte(255) - i) CByte(2)
End Function
and
Function ReduceDistanceTo255(ByVal i As Byte) As Byte
Return CByte(i + (255 - i) 2)
End Function
[code]....
The first one is just plain ugly and hard to read, because every literal needs to be CByted. The second one performs calculations in integers and then converts the result to Byte, which is OK, but not as elegant as a pure-Byte operation. The third workaround doesn't require CBytes, but it's drawbacks are obvious.
Embed XElements Into XML Literals?
Jul 26, 2010In VB.NET I can easily embed strings into XML literals using <xml><%= "my string" %></xml>. How can I embed an XElement instance? I know I can use methods on the XElement, XNode, etc classes, but I'd like to do it in the XML literals if possible.

IDE :: Using XML Literals With Abstract Xml Types?
May 3, 2011I'm trying to use the builtin XML literals feature to create/read xml files using my own schemas, but I don't see a way to cast an abstract XElement from a base type to a more derived type.The schema/xml below shows in general what I'm working with, but using XML literals only allows me to use the base type in the IDE, so the xml below is treated as a collection of elements of the base type, instead one of the base type and one of the derived type.
<schema targetNamespace="Test" xmlns="Test">
<xs:complexType name="Base" abstract="true">
<xs:attribute name="Id" type="xs:int">

Setting Attribute Value In XML Literals?
Jun 5, 2009As basic as this is, it took me a few minutes to figure out, so wanted to share with the rest of the community to avoid anyone else from wasting their time.
I am attempting to generate the following XML string using VB.NET XML Literals
<Books>
<Book Name="The First Book" />
<Book Name="The Second Book" />

But the compiler is complaining about the quotes that are supposed to surround the attribute value. I tried using single quotes, two double quotes, nothing works.
Using Control Structures In XML Literals?
May 4, 2009My problem is that I want to include control structures in the embedded XML. Specifically, I want to include or exclude an entire element (not just its contents) based on a boolean expression. The question extends to other control structures as well though.
I'd expect the <% %> syntax to support inling of code but that doesn't seem to function in VB.net's implementation (as opposed to the <%= %> for inlining the result of an evaluated expression, which does).
Here's some very simple code by way of example only.
Public Class Foo
Private bar As String = Nothing
Private baz As String = Nothing
[code]....
I'd much prefer to use the format of getXMLBad() if possible. In this short example it doesn't seem critical, but in much larger examples, the inlining of the logic is more readable and maintainable than the "assembly" style in getXML(). This especially true when the logic is in the middle of large block of static XML and when coding to a very strict or complex schemas.I'd be interested in the capability to extend this to Looping constructs as well.

XML Namespace And Literals - Property Group Nodes
Apr 28, 2011I'm experimenting with xml literals in vb.net and there's something I don't get. Here's a small sample that illustrates the problem. I'm adding two PropertyGroup nodes to an empty Visual Studio project. The first one is added as xml literal, the second as new XElement:
Imports <xmlns="[URL]">
Module MyModule
Sub Main()
Dim vbproj = <?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="[URL]">
[Code] .....
This code writes the following output:
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="[URL]">
<PropertyGroup xmlns="[URL]"></PropertyGroup>
<PropertyGroup />
</Project>
As you can see, the first PropertyGroup node contains a redundant xmlns declaration. Why is that, and can it be avoided?

Literal Substitution - Instantiate Form Objects Using Variables As Literals
Oct 23, 2008What I need to do is create comboboxes populated with values from a CSV for each class object selected from an Active Directory schema.
So lets say twelve classes are selected, the next form will display the class names in a checkedlistbox and will require twelve comboboxes for associating AD classes to CSV fields. Since the number of AD classes selected will always vary, is there a practical way to code it so that the objects can be instantiated from values stored in a variable?
Other languages support macro substitution, where the variable's value is interpreted as a literal at runtime. Developing in Visual Studio 2005, VB version 8 .netFramework 2.0xxx

IDE :: Exiting Out Of Intellisense?
Mar 14, 2010I find myself frequently turning off Intellisense because it adds wrong choices to my code. For example if I try to type "i " (without the quotes) it causes "int " to be put into my code. If I type "for " it may put "form " into my text.
Reaching for the ESC key constantly slows down my typing. (It's such a long way to reach for small hands). Is there an alternative way to exit out of intellisense without the highlighted choice being placed into my code, or is a way I can define a different key for this purpose?

View 9 Replies.Net 2008 IntelliSense Odd Behavior?
Jul 26, 2011I am primarily a C# developer; however, I am currently working on a project for a client who preferred VB.net. I have managed to switch over fairly well, with one frustrating exception. When editing a C# file in Visual Studio pressing enter will select an item out of the IntelliSense window and keep the cursor at the end of the selected statement.
However, when editing a VB file, pressing enter selects the item out the IntelliSense popup AND moves the cursor to the next line. I realize that this is a small thing, but it drives me crazy, because it makes it really hard to switch between C# and VB projects.
I have searched for everything I can think of in Google and found nothing. Does anyone know of a way to change the IntelliSense selection behavior?

C# IntelliSense Delayed Compared To .NET?
Jun 6, 2010In VB.NET projects, errors are highlighted immediately after cursor leaves the line. In C#, I have to wait several seconds for IntelliSense to highlight it. Also, the C# version doesn't show all project errors in "Errors List", unless you start to build it. Actually, it seems to work differently in every way. Is it possible to adjust that behavior?
I am using both Visual Studio 2008 and Visual Studio 2010.
