I am puzzled by the presence of error 232: "Reference to a non-shared member requires an object reference" when I use the snippet below in a larger program after testing it successfully as a stand-alone subroutine. The offending line is:

When I generate code using T4 templates in Visual Studio 2010, I get the following error for each of my asp controls when I try to compile: Control "ddState" is missing required attribute "showat".
I have never gotten this error in previous versions of .NET. Further, I don't get this error when I manually construct my pages either by dragging/dropping, nor do I get it when I type out the control text myself. When I generate code, I have to manually add showat="client" to my tag for the compiler to be happy. It was my understanding that I never had to explicitly specify this tag. The following:
<asp:dropdownlist id="ddState" runat="server" showat="client" />
solves the problem. Why do I have to add this to generated code but not other times?
(It's a VS-2010 webforms project, using VB, in case that makes a difference.)
I keep on getting errors for every line in the code below that tell me that the attributes cannot be applied multiple times. What does this mean and how can I fix it without changing what the code does?

I have a vb .net program on visual studio 2005. I modified my code for a bug fix. When I am rebuilding and running the application, it shows me the old version of my program, ie, the new changes are not taken effect. To test more, I changed a Label box text and tried to rebuild the program. The program shown me the screen with the old label text. The change was not affected. I tryed to save the application, close, reopen , unfortunately the same effect. Then I copied the project folder to my other laptop to see if visual studio had anything wrong. But then there also I am facing the same problem.

I am currently writing a website for a company to display their products to their customers. One of the things I am putting into it is the ability to add news items onto the homepage, only part of the admin side of the site.
I have managed to extract some news items from the database, and display them dynamically in a Web User Control which I have added to Default.aspx. I have managed to add buttons for "Update" with events. The problem is that, on clicking one of these update buttons, the page reloads with the theme applied (as it should), but the css files from the theme do not apply - the body text is bigger than it should be and changes back to the default font. I know the skin files apply as I have tried setting all button backgrounds to black by default. The css files seem to apply to any text which is generated from clicking an update button (I have it so it writes the title of the news item for the button that was clicked. This text is the size and font it should be). I have spent HOURS trying to work out why this is happening, with loads of Googling but no success. It is almost as if the theme is being applied between the PageLoad event and the ButtonClick event, but the skin files would say otherwise. Does anyone know why this is?

I have the [B] [I] [U] buttons and they work to a point but here is the problem I'm having.In MS Word,I can Hilight text and select Bold and it bolds the text, I can then select Italic and while leaving it bold, it Italicizes it.I can then click the bold button again and it will remove the bold but leave the selected text Italicized. I can't figure out how to get this action to work.I know I can OR the styles to apply multiple styles to the text but I don't know how to remove a style while maintaining any others applied.Here's a section of code that I'm messing with.[code]....btw, I am using for the comments so that the code is easier to read.I have tried (in this specific segment) newFontStyle = currentFont.Style And Not FontStyle.Bold

Once the search is executed I want to be able to click "refresh" and the original table is then shown in the datagridview. If I try adding after the search sub is completed:

Next, I put an instance of MyButton into a property grid, expand property MC and edit SubProp2.From the type editor for SubProp2, I want to get hold of the attribute applied to property MC.Looking at the context,PropertyDescriptor.ComponentType, we arrive at Type: MyClass.If i look at the attributes applied to MyClass, though, it will only return the attributes applied directly to MyClass, and not the extra attribute applied to the property MC.

When I deployed my project on a server, in certain circumstances, I get an error page that indicates I should create a custom error page. I was wondering how exactly I would implement this custom error page the server asks for to give me a precise and helpful message or preferably, how I would get the error to just display on the main page?This is the error message I got below
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
[code]....
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

I recently created a windows service that starts other applications that I use on windows startup. Basically this service is for virtual computers i use to test software and web sites. The service starts and stops just fine but when a custom made application actually is run within the service I get a .Net error in my event logs. Ive read up online and found that this is caused by an unhandled exception (As a result of this error in version 2.0 of the framework the application is killed.) so i added the correct handler and it didn't work. Then i found that another issue could be .net being corrupt so i uninstalled and reinstalled still no fix. I know theres an issue with one of my applications but i cant find were. I don't get any errors when i debug anyone know what i should do? [code]
