XAML Named Element Not Found By FindName

Jun 20, 2011

I am having problems finding an named object declared in XAML in my codebehind file.I want to initalize a ViewModel from inside my View. However I also need a reference to the ViewModel in my code behind file (basically for navigation support, handling events, etc. that I cannot do easily from my ViewModel)[code]However I get a null reference exception when I'm trying to access the ViewModel in my code behind:[code]Some more research shows that the FindName call for "ViewModel" in InitalizeComponent returns null. I tried reading up on XAML namescopes etc. but as far as I see, this should be a simple case and just work, no?

VS 2010 Check For Element Or Keep Trying Until Element Is Found?

Feb 21, 2012

I have been doing well and also I am a noob I know it and you know it a lot has started making sense and I am evening figuring new things out without using Google but of course I have hit another snag in my program so here goes

I am waiting for an email to arrive (the page automatically refreshes) and then I want to click the link (I do not need to click to open the email or anything like that) I also have the code to click and navigate to the address reason being it was the only way I could figure out how to stop it opening in a new window on IE

So my only problem is I need a way to check every x seconds for the element and then if its there proceed with my code and if its not wait and then check again or however this is done in VB.If this is not the way its done please point me in the right direction the code I am using to find and then navigate to the link is

Dim emailpageelements As HtmlElementCollection = WebBrowser2.Document.GetElementsByTagName("a")
For Each emailver As HtmlElement In emailpageelements
If InStr(emailver.InnerHtml, "https://twitter.com/account/confirm_email/") Then
WebBrowser1.Navigate(emailver.InnerText)

Namespace Or Type Specified In The Imports 'MS.Internal.Xaml.Builtins' Doesn't Contain Any Public Member Or Cannot Be Found?

Feb 26, 2010

I have a WPF VB.NET project in Visual Studio 2008. For some reason, Visual Studio thinks that it needs to add anImports MS.Internal.Xaml.Builtinsto every auto-generated XAML partial class (= the nameOfXamlFile.g.vb files), resulting in the following warning:warning BC40056: Namespace or type specified in the Imports 'MS.Internal.Xaml.Builtins' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.I can remove the Imports line, but, since this is an auto-generated file, it reappears every time that the project is rebuilt.

One Dimensional Array Named Sales Which Will Refer To Ninth Element?

Mar 2, 2010

How do I determine from these codes in a one dimensional array named sales which will refer to the ninth element?

sales(8)
sales(9)
sales.Item(9)
sales(10)

My thought is that the 3rd code will refer to the ninth element in the array.

VS 2005 - DGV Row Updates And Filters - Error: Column Named Cannot Be Found

Sep 8, 2011

Scenario: FormA has a DataGridView with a DataTable as it's DataSource. The DefaultView of the DataTable is set to a particular filter, say "UnitFreight < 2.00". The user selects multiple rows then selects a context menu item to open up form2. Form2 does a bunch of stuff and in this example it will change the UnitFreight value in the selected rows on form1 to say 2.27. It also raises an event in form1 to adjust attribute cells such as UnitPrice.

The issue is that doing the above example puts the selected rows out of the range of the applied filter and I believe this is the issue because I end up getting a "Column named UnitPrice cannot be found" error. This is happening during the update of those attribute columns. I'm guessing the row has been filtered out so there's no column to be found. If I do the update without the filter applied it works fine. So my question is, what's the best approach to updating the data in this situation. I've started converting the updates to work against the DataTable directly instead of the DataGridView.

Asp.net - Element 'system.webServer' Has Invalid Child Element 'rewrite'?

Feb 14, 2012

I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:

Wpf - Programmatically Set Height Of Row In XAML?

Jul 26, 2009

I'm doing a WPF project and decided to try it out with Visual Basic. So, basically I'm trying to set the height of a row in a Grid. I'm not great at programming but with C# I managed somehow to figure it out, without remembering how. It actually looks like an animation because when clicking the button, the height of one row smoothly goes down to 0. But I'm trying to even reach that property and I can't figure out the context. The row is called "AnimationRow" and I can reach that, but where do I set the height?

.net - Xaml TextBlock Width Inconsistent ?

Jan 18, 2012

Look at this simple bug :
