WebMatrix :: Web Development 101: Part 6 Possible Errors?
Jan 17, 2011
keep getting an error when hitting the submit button on my form.An SqlCeParameter with ParameterName '3' is not contained by this SqlCeParameterCollectionI have tried changing variables around and have resorted to copying and pasting the tutorial code. Is there possible an error in the tutorials code?I am pretty new to working with dynamic web pages and an extremely frustrated trying to follow this tutorial.My code is as follows:
I've followed this training without problem until Part 6. When I get to the last execise on the page "Adding to the Database" my form does not work as expected. Here's the code for my AddMovie.cshtml:
@{ var MovieName=""; var MovieGenre=""; var MovieYear=""; if(IsPost){ MovieName=Request["formName"]; MovieGenre=Request["formGenre"]; MovieYear=Request["formYear"]; var SQLINSERT = "INSERT INTO Favorites (Name, Genre, ReleaseYear) VALUES (@0, @1, @2)"; var db = Database.Open("Movies"); db.Execute(SQLINSERT, MovieName, MovieGenre, MovieYear); Response.Redirect("dataMovies.cshtml"); } } <h1>Add a New Movie to the database</h1 <form action="" method="post"> <p>Name:<input type="text" name="formName" /></p> <p>Genre:<input type="text" name="formGenre" /></p> <p>Year:<input type="text" name="formYear" /></p> <p><input type="submit" value="Add Movie" /></p> </form>
I get the Add Movie submit button, and I've rechecked several times, but I cannot find why 1) the data is not added to the database and 2) that the redirect does not send me back to the start page dataMovies.cshtml (which is working fine).
I got these errors while trying to run a web application using vs 2008, The first error is this: >Application has generated an exception that could not be handled. >process ID=0x1130 (4400), Thread ID=0xe6c (3692). And when I press OK a second dialog reports this error:>unable to connect to the asp.net development server. I reinstalled, repaired and re registered msdbg2.dll and edited hosts file but still get this error. I need to debug an application but I can't. This error is on a 'Win 2003 server enrterprise service pack 1' with a vs2008 team system installation. What can I do to remove this error and run and debug my application?
I have a Web App (VS 2010 Beta 2, using VB) and it works flawlessly on the development system. When I publish it, everything works fine unless I use an update panel. If I use the update panel, and try to use something such as a dragpanel, I get the following error.

I've found a Webmatrix help article that says MS Webmatrix "publishes the (SQL Server or MySQL) database by creating scripts that run in a database that has been created for you by your hosting provider." That is wonderful, except I can't get it to work when I'm trying to publish a MySQL database (backing wordpress) through FTP (my hosting provider does not support 'web deploy'). Again, no problem, since it is already documented that " FTP protocols cannot be used to publish MySQL database. " But this does not excuse Webmatrix from generating MySQL database install scripts for me. During the publishing step, no database install script is generated - at least that I can tell - and there is no manual option to create a database export / backup / install script.
In short, as Webmatrix goes, I'm dead in the water trying to get my database uploaded to my hosting provider. Does anyone know the trick to force Webmatrix to create the MySQL database install scripts on my local box? Once created, I can take-over the upload and install process.
I'm wondering if it is possible to include Microsoft.Data.Entity.CTP.dll reference to WebMatrix site and if the Compact edition of the database would support it? I'd kinda love use something like
code-first development in my WebMatrix project. I think is even easier than writing SQL-s into the code...
I started the Bakery site demo...everything runs fine on my local machine.When I publish the site to production server in w2k8r2+iis7.5 and with .net 4.0 (integrate) pool, my bakery apps not able to connect to the .sdf file.
Error I got is :
Connection string "bakery" was not found. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidOperationException: Connection string "bakery" was not found.
Source Error:

Line 3:
Line 4: FacebookSocialPlugins.Initialize("[xxx]", "[xxx]","bakery");
I struggle with publishing 2 databases from WebMatrix using WebDeploy. On Publish settings screen I specify 2 different connection strings, but on Publish Compatibility screen Database names in both destination connection strings are equal. When I return to settings screen, original value is replaced there as well.
How destination server connection strings are evaluated? Here are connection strings from the root web.config file, which are set by hidden parameters in my parameters.xml:
If I create two websites using the starter site template logging into one shows me logged into the other.
Here are the steps:
Create starter website called website1 Create starter website called website2 Run both websites in the same browser, firefox Register an account in website1 Log out of website1 Log back into website1 Refresh website2 and it shows my login name from website1 Has anyone else encountered this?
I'm often experiencing that keyboard shortcuts stops working in WebMatrix. This is very annoying as CTRL-S, CTRL-C, CTRL-V, etc. stops working, all of which are heavily used when programming. It's obviously hard to explain how to reproduce this, but I waswondering if someone knows a quick-fix?
There I was, happily coding webpages, when suddenly it wouldn't run them anymore. Now when I click run I get an error message that looks like this: Server Error in '/' Application.This type of page is not served. Description:The type of page you have requested is not served because it has been explicitly forbidden. The extension '.cshtml' may be incorrect. Please review the URL below and make sure that it is spelled correctly.
Requested URL: /quiz/intro.cshtml Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1
My hosting company states they support .net and razor. However after uploading my website made with webmatrix and razor *.cshtml pages. When i visit my website all i get is 404.17 error messages. As an testcase i decided to add an standard .aspx page. Visiting that page gives the same 404.17 error message :-( .
According to my webhoster my web.config is wrong. However that one is generated by webmatrix. Besides my *.cshtml *.aspx a lot of files and directories are added to the bin folder. What can i check and what should my hosting provider check. When using the check compatibility the asp.net version is shown as unknown? My hosting provider claims my site is running asp.net 4.0 in integrated mode and that should be enough.
It's unfortunate that Microsoft WebMatrix (beta) doesn't recognize that files has been modified. I suggest you implement a feature similar to Visual Studio, allowing the user to decide what to do if the file has been modified outside WebMatrix. Especially when you have a button to launch the project in Visual Studio, it should have better support for "dual-development", cause at it is now, code can be overwritten by mistake easily.
I got the first beta of WebMatrix, downloaded Drupal, and got a site more or less going. I then tried to move it to two different hosts - first the IIS server running on my own domain controller, then to my hosting service. I dumped the DB with mysqldump, and imported it to the databases running on each server. Then I ftp'd the code and configuration files to both servers, and made appropriate configuration changes (primarily the mysql connect string).On both servers I have the same problem: The site comes up in its home page and looks great, but as soon as I log in as the site admin, I get a 404 (not found) error. Since it looks like virtually everything in Drupal is driven from the database, I really haven't the faintest idea where to start debugging this.
We have several asp.net web applications we've built and we also want to embed them into various sharepoint pages. We need to have them look like standalone applications when viewed in their own pages, but also have them look like they fit within the sharepoint page when embedded. We are doing this currently with IFrames and it works ok, but I'm wondering if there is some sort of proxy web part where we can configure the web part to point to an existing web app and it will proxy the contents through from the web app into the sharepoint page removing the need for an IFrame. Possible?
I have a C# web forms ASP.NET 4.0 web application that uses Routing for URLs for some reason custom errors defined in the system.web section of my web.config is entirely ignored and it will fall back the IIS errors.
This gets entirely ignored
[code]....
This would be a minor inconvenience except that by the fact it falls back to IIS native instead of my application it completely circumvents Elmah logging my 404 exceptions correctly.
I have four columns in database. Consider it as a,b,c and d. I'm trying to place a and b column values in TO part and c and d column values in CC part in outlook. a,b,c,d contains six digits numeric values. I just need to place a and b columns values in to and c and d values in cc part on click of a button.
When using SPWeb.GetCatalog(SPListTemplateType.WebPartCatalog), it returns an SPList which of course contains a SPListItemCollection of the web parts in the web part gallery. When looping through the items, is there any easy way to get properties of the web parts? Such as AllowClose, CatalogIconImageUrl, etc... I know I can probably accomplish this using the listItem.OpenBinaryStream etc and loading the xml of the .webpart file, but I wondered if there was an easier way to do this.
I am having all sorts of trouble with webmatrix hanging on me and was wondering if someone could test the following to see if it is isolated to me?
If I create a new empty site and add a single php page to it and then try to type the following line webmatrix will hand as soon as I get to the ? after src="
right now I playing around with WebMatrix and I followed the tutorial from http://www.asp.net/WebMatrix. Chapter 6 (displaying data in a grid) described how to use a WebGrid helper very clear, but the data in the example is always retrieved from an SQL DB.I want to use the same XML file from chapter 7 (Displaying data in a chart).Using the code:
... var DataSet = new DataSet(); dataSet.ReadXmlSchema(Server.MapPath("/App_Data/QCFiler.xsd"));
We have a largely asp.net web form team (With some Oracle developers thrown in).
Question 1:
Is it a good idea to start using asp.net MVC which will mean redevelopment of a number of standard controls for not much benefit.
Question 2:
Is it a good idea to hire developers where there most recent skills are with asp.net MVC?
I doubt there is any benefit adopting MVC now, given the 100+ applications in this suite of products, and the maintenance/rework this will cause. Given this, is there any particular reason to hire MVC developers, as they won't be hitting the ground running, which is what I need now.
