Web Forms :: NullReference Exception Unhandled By User Code?
Mar 18, 2011I'm working on having two forms that communicate together. In order to do this, I am passing public value from the source page. Here's how I did it:
In the source page I have:
Public ReadOnly Property CurrentCity() As String
Get
Return txtboxfake.Text
End Get
End Property
Then under page_load of the page I have:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
txtteam.Text = PreviousPage.CurrentCity
txtboxdate.Text = Calendar1.SelectedDate
End Sub
For some reason I keep getting an error that says "NullReference exception unhandled by user code" that points to txtteam.text = PreviousPage.CurrentCity.

System.Web.HttpException File XXX.has Not Been Pre-compiled, And Cannot Be Requested?
Nov 10, 2010I ran into this error today and much googling didn't get me the answer. I have been for years now publishing this particular site by simply doing "Publish web site" and then supplying it a UNC path, then I go to the server delete the old bin and copy to the new bin folder to the live site, this has always worked except today I started getting the "cannot be requested" error for certian pages in certain directories. Everything else worked and after several attempts nothing else broke and only these same certain few pages where screwed up - there was nothing exciting about any of these pages, in fact they were part of the admin portion of the site and were very simple

.net - System.Web.HttpException Could Not Load Type '[namespace]?
Feb 7, 2011This started as Could not load type 'Global' error. After I tried a few things and getting no where I deleted the Global.asax file and now the error is Could not load type '[namespace].???'Where ??? is the class name of every page I try to load.The web site (when executed within VS2008, local dev computer) works fine but once published (with no errors) and deployed to the server gives me Could not load type '[namespace].???' error
I did install elmah and I was able to get more details for this "generic" Could not load type '[namespace].???' error
elmah reports a HTTP error 500 :
System.Web.HttpException Could not load type '[namespace].???' ->
System.Web.HttpParseException: Could not load type '[namespace].???'
I have checked the "basics"

Doing a clean and a build Checking the Inherits attr in the HTML against the code behind
UPDATE #1 I did deploy the site to a different DEV computer (configured IIS, virtual folder, etc.) and it works. When I use the same published code on the server, get the generic Could not load type '[namespace].???' error
UPDATE #2 I created a test web app. One form (Default.aspx) with a button. The click event does a Response.Write("Hello World"); I moved this app to the server and guess what, I get the Could not load type TestSite._Default
UPDATE #3 According to the fusion log viewer, these two websites are attempting to load CppCodeProvider and VJSharpCodeProvider, but I have no references to any of these. After a Google search, I found this post.I checked and I have no references to JAVA files.
DataSource Controls :: Reading Excel Files To Store Into Sqlserver Database - OleDbException Was Unhandled By User Code
Feb 1, 2010i've got some problem reading excel files to store into sqlserver database. currently my code has a fileupload control and a button for me to save the excel file into a folder and read the data inside the excel file and write it into the sql database. The code works only if the excel sheet name is Sheet1.xlsx, however i tried upload a diff file named ImportUserFile.xlsx and it gave me the exception below. 'ImportUserFile$' is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long. i have also tried other file names and it seemed only Sheet1.xlsx works.

Forms Data Controls :: Throw The Exception Back To Page_Load Error: ArgumentNullException Was Unhandled By User Code
Nov 19, 2010I'm trying to throw the exception back to Page_Load but the throw statement causes error: ArgumentNullException was unhandled by user code. How can that be fixed? Also, I can't see Label1.Text displayed on the page after the ArgumentNullException occurs because the page is not re-load. If there is no exception, it's fine to not reload the page. How can I see the Label1.Text displayed?
