When we build a Custom User Control a violet wheel appears as the icon for the created control in the toolbox. I read it can be changed through the ToolboxBitmap attribute. But the one line code with bitmap location specified as a string argument is not working.
I have a dropdownlist in a template field of a gridview. I am tryin to change the width of the dropdownlist is display all the values when I mouse over and then change the width back when you mouse out. Here is the code:

I works great when I mouse over but the mouse out doesn't change in back? am I doing something wrong?
How would I add a toolbox bitmap to a control in vb.Net? I did find the <ToolboxBitmap ...> statement, but I'm still confused on the best way to use it. I also haven't found a good explanation of actually adding a bitmap resource to a project.
i'm having trouble adding an Icon for the Toolbox on my UserControl.I'm using the following:
<ToolBoxBitmap"CovButton.bmp")> _
I have CovButton.bmp added to the project and have it's build set to 'Embedded Resource'.However i can't compile it because i'm getting an error with the line continuation character saying the following "Attribute specifier is not a complete statement. Use a line continuation to apply the attribute to the following statement.".If i remove the space between the > and _ it gives me the error "Line continuation character '_' must be preceded by at least one white space and must be the last character on the line."
I get an error when I try to build my project.'SSLAccessFiltercannot' be used as an attribute because it does not inherit from 'System.Attribute'. [code]
I have created a loop to display the results. In the snippet above, how do i grab the attributes name(name, length, slope, and level_of_height). I have used reader.name is giving me RUNWAY which is correct as the elements name. I tried getAttribute and it give me all of the values of the attributes, but not there name.

I have been parsing xml content using the xmlreader and cannot use the xml document but so far it works getting all elementcontent except for the attribute contents. I need to parse the link below found in the following entry;[code]
In my VB 6.0 code, I declare have the following line[code]...
However, in VB.NET, I get the error "expecting declaration". Isn't this a declaration statement? Is there a good reference for finding the differences between VB.NET and VB 6.0?
I am converting C# code to VB.Net and the C code has this above the function:[return: System.Xml.Serialization.XmlElementAttribute("Name", IsNullable=true)]
what im trying to do is, i have the following xml:
Postcode id="E20 2AP" from="test1" to="test2"/>
im tring to search for the postcode id and then get the from and to text from that id the code i have:
Public Shared Function GetFromDate(ByVal PostCode As String) As String Dim LoadToAddresses = From ex In doc.Descendants.Elements("Postcode") Select New With {.accountName = ex.Attribute("id").Value, .datefrom = ex.Attribute("from").Value}
It appears that my favorite thing in the world is tackling projects that are beyond my current knowledge and abilities. I have a little project that I am working on which is a simple image viewer stocked with (upon completion) your standard Load..., Next/Previous, Zoom In/Out, Actual Size, and Full Screen capabilities. However, I am running into a few snags:
(1) I've been able to get my "Load..." button to display a file dialog box, but I cannot seem to get a working filter (with which only image file types are allowed to be selected) in working order.
(2) I have a PictureBox object (entitled PictureBox1) that displays the image selected via the file dialog box, but it loads images in their full size (1:1/100% zoomed) state without scrollbars, etc. to allow me to navigate the loaded image. I would like to have it load the image, initially, to fit within the dimensions of PictureBox1 and from there be able to zoom in/out via my "Zoom In/Out" and "Actual Size" buttons and be able to scroll if the zoom level is beyond the dimensions of PictureBox1.
(3) It dawned on me that I haven't the faintest idea how to get my "Next/Previous" buttons to allow the user (me) to navigate, in succession, the images contained in the folder in which the currently loaded image is stored. [code]

A former co-worker wrote a class in C# that was to be used as an attribute. I'm having to convert his work to VB (yeah, it's pointless and way more work than necessary, but management thinks it's a good idea). Unfortunately I'm having an issue because one of the main properties of the class is an ArrayList which is set with a ParamArray in the constructor. The class looks like this (note I've tried to abstract out the problem, so this is a simplified version of the class only)
<AttributeUsage(AttributeTargets.Field Or AttributeTargets.[Property])> _ Public Class LabelAttribute Inherits Attribute Public Sub New()
[CODE]........
In the first one, there is just the single label being added. No Problem. In the second one there are 2 different labels being added. Again, no problem. The third one, however, is a problem because it's assuming that the "Description", which is supposed to be the description is instead being interpreted as another label.
This wasn't a problem in C# because it could be set as follows:
[CODE].................
Of course this doesn't work in VB because optional parameters aren't referred to by name as they are in C#. As a stopgap I've changed the constructor to allow only a single label like this
CODE]..................
But that undermines some of what this class is meant to do. Does anyone know how, or even if I can get the same basic functionality to work in VB?
Think there must be a way to make the existing design work. Imagine this class was built into a library that I could not modify. Would I be forever forbidden from setting Description because of this design?
How can I shift the GET-implementation of a Class property to a / using a custom attribute? (I've added instantation vars (classname, propertyname) to the attribute, however I'd rather have these automatically fetched ofcourse.)

This is my Effect.xml file .I am using vb.net to access this xml file. Actually i want to access effect name when i enter particular effect id.So that i will get attribute value of effect name when i give effect id as input value How can i do using vb.net
I'm using VB 2008 and I'm trying to add a xmlns="mynamespace" attribute to an XDocument's root element.The XML document is created by a 3rd party, and I have loaded it into a VB XDocument object. As it comes, it has no namespaces. I have been working on a local copy and I added in a namespace in a text editor, so that I can use the XMLToSchema in VB to enable intellisense etc, as per the instructions in the Beth Massi vids at MSDN. Now the rest of the code works I want to open the live documents again. Without the namespace, my XML literals don't resolve.I've tried unsuccessfully to add in the XMLNS property to the root tag using a few methods, and the nearest I got was the following three code samples.
Dim myNS As XNamespace = "urn:nbf:namespacename" myXML.Element("nameofrootelement").Add(myNS)
^^^^ The namespace was added as the value of the root element, not as an attribute.
XML.Root.Add(New XAttribute("xmlns", "name"))
^^^^ Generated the error: Run-time exception thrown : System.Xml.XmlException - The prefix '' cannot be redefined from '' to 'name' within the same start element tag.
but
XML.Root.Add(New XAttribute("test", "name"))
^^^^ works correctly. Presumably it doesn't like me manually trying to set a reserved attribute? This namespacing seems way too over complex from some of the Googling I've done.I thought to .ToString it, then modify, then .Parse it also, but I wanted a better solution so that it would help me understand it a little better! I did try this though, and as you rightly point out, it affects all the descendants too, so thus it still breaks.
I will be working with multiple XML feeds all produced by different third parties, and I think for simplicity I will be leaving out the namespacing entirely!My own custom parsing function rewrites the third party feeds into one uniformed document, which then gets processed by another routine. I'll be able to add a ns to that intermediate piece of XML which will help when coding the secondary function.
I have a page, divided into 3 section. Left Menu, Middle and Right Menu. Left Menu data comes from control, Middle Menu data is sorted on a page and Right Menu links also depends upon page to page so they are set on a page itself as
