WebMatrix :: Getting Data On A Post From The Request Object Returns No Values?
Mar 23, 2011
I am new to webmatix and I do not do much development. I was trying to get some values from a request object and it's probably something very stupid I am doing wrong but really I cannot see what it is. This is the code I am trying to use, but I get no value from any items from the form:
@{
Layout = "_SiteLayout.cshtml";
Page.Title = "test";
if (IsPost)
I know how to retrieve a GET object with Request.Querystring("objname"), but how do I receive POST variables using the Request object, or somehow through the code?
I have the following code where the function codeaddress geocodes the text feild value and returns geocoded value , geocoded value is stored in variable example ,how will i return the variable v2 to the function call and post to asmx webservice.
this works fine on my local site but as soon as i upload the site to my live server i get stem.NullReferenceException: Object reference not set to an instance of an object
on the first line of this:
if (!Page.User.Identity.IsAuthenticated) { pnlSignIn.Visible = true; pnlSignOut.Visible = false; }
private void FillDetails(string pId, out string Name, out string Address)
[code]....
I have method called Filldetails(),This method uses stored procedure to retrieve information for product name and address based on productid passed from productdetails table.I am working on globalization project.We have this product information for US country but there is no product information for germany country.So dataset is empty for germany.As result I am getting error object reference not set to an instance of the object.
[WebMethod] [SoapHeader("_webServiceAuth")] public User GetUser(string username){ try { this._validationMethods.Validate(_webServiceAuth); User user = new User(username); [code]...
I am using an Zencoder API to transcode video files. Once the job is completed they will do a HTTP POST with XML or JSON data containing the Job ID and other info to the url we provide.
So if URL is www.abc.com/GetZencoderResponse.aspx or .ashx, how can I read the data they post?
excuse me for the underlines, i thought that would make my query stand out.
How can i see if a check box was checked with razor. I am trying to do Request["checkbox"] and it returns nothing. (checkbox is the "name" of the checkbox).
I've got this application that works locally and when deployed and using a .mdf SQL Express database file (which I usually use for testing purposes). However, when I change it to work with our SQL Server 2008 the app works but the service doesn't. For example if in my code behind of a page I have a button that adds data to a table such as this it works fine:
public static string connString = @"Data Source=server1;Initial Catalog=Project;Integrated Security=True"; protected void btnAddProj_Click(object sender, EventArgs e) { using (var sqlc = new SqlConnection(connString)) { sqlc.Open(); var cmd = sqlc.CreateCommand(); int intProjectID; // Add the project info to the database cmd.CommandText = "INSERT INTO tblProject VALUES(@ProjName,@ProjTeam,@ProjStart,@ProjEnd)"; cmd.Parameters.Add("ProjName", System.Data.SqlDbType.NVarChar).Value = txtProjName.Text; cmd.Parameters.Add("ProjTeam", System.Data.SqlDbType.Int).Value = ddlTeamSupported.SelectedValue; cmd.Parameters.Add("ProjStart", System.Data.SqlDbType.NVarChar).Value = txtStartDate.Text; cmd.Parameters.Add("ProjEnd", System.Data.SqlDbType.NVarChar).Value = txtEndDate.Text; cmd.ExecuteNonQuery(); } }
My web.config is setup to use impersonation on that server and all works perfectly well. However, for my service the query doesn't seem to return anything and I get a 400 Bad Request error. The code for the jquery is:
$.ajax({ type: "POST", async: false, url: "Services/ProjectService.svc/test", contentType: "application/json; charset=utf-8", dataType: "json", success: function (data) { console.log(data); } }); And for the Service: [ServiceContract] public interface IProjectService { [OperationContract] [WebInvoke(ResponseFormat = WebMessageFormat.Json)] ArrayList test(); } public static string connString = @"Data Source=server1;Initial Catalog=Project;Integrated Security=True"; public ArrayList test() { var sqlc = new SqlConnection(connString); sqlc.Open(); var cmd = sqlc.CreateCommand(); cmd.CommandText = "SELECT ProjectID FROM tblProject"; var reader = cmd.ExecuteReader(); ArrayList temparray = new ArrayList(); while (reader.Read()) { temparray.Add(reader[0]); } sqlc.Close(); return temparray; }
If instead of querying the database I have the service just return static data then it works fine. What could cause my service not to be able to connect to the database when the rest of the code behind for the app works?
I am following the tutorial on the webmatrix site (http://www.microsoft.com/web/post/web/post/Web-Development-101-Part-6-Creating-an-Add-Data-page). Ifinished creating the AddMovie.cshtml page, but when I try to execute it, I get the following exceptionAn SqlCeParameter with ParameterName '3' is not contained by this SqlCeParameterCollection.Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
I have a wcf service that randomly begins to fail when requesting the autogenerated javascript that wcf supports making. But I have no luck tracking down why. The js thing is part of the wcf featureset, so I dont know how it can suddenly begin to fail and be unable to work until IIS is recycled.
The http log gives me:
2010-06-10 09:11:49 W3SVC2095255988 myip GET /path/myservice.svc/js _=1276161113900 80 - ip browser 500 0 0 So its an error 500, and that is about the only thing I can figure out. The event log contains no information.
Requests to /path/myservice.svc works just fine. After recycling IIS it works again, and some days later it begins to fail until I recycle IIS.

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'm experiencing a really confusing error. Exactly every other time the page returns
ERROR [23000] [DataDirect][ODBC Progress OpenEdge Wire Protocol driver][OPENEDGE]Integrity constraint violation:uniqueness constraint violation (7518)and else it works nicely.
Here's the SQL:
SELECT SlsOrder.Orderdate, SlsLine.LineNum, CASE WHEN SlsLine.AllDelivered = 1 THEN 'X' ELSE '0' END AS 'AllDelivered', Item.ItemName, Item.TechName, SlsLine.IntDlvDate, SlsLine.OrderNum, SlsLine.ItemCode, SlsLine.Version, CEILING(SlsLine.Qty) AS 'Qty', Item.QtyUnit, ROUND((SlsLine.Price*SlsLine.Qty),2) AS 'rowSum', ROUND(SlsLine.Price,2) AS 'Price', IFNULL(SysText.InfoText, '-') AS 'InfoText' FROM PUB.SlsLine INNER JOIN PUB.SlsOrder ON (SlsLine.OrderNum=SlsOrder.OrderNum) INNER JOIN PUB.Item ON (SlsLine.ItemCode=Item.ItemCode) LEFT OUTER JOIN PUB.SysText ON (SlsLine.SlsLineKey=SysText.SysTextKey) AND SysText.NoteType = 'OrdConfRowE' AND SysText.ConsTxt = '' WHERE (SlsLine.OrderNum = '" & o & "') ORDER BY SlsLine.LineNum
I have a webservice, it has few webmethods. when i create a client proxy and invoke the methods to check its response, i am getting this error. Can someone tell me what things can i check to know the cause of this? The error is not saying much hence blocked on this.

I have a dynamic catalogue, where customers select products they are interested in. The manager of the company I am doing this for would like to be able to create an up to date offline catalogue at any given time, to send out to customers who dont have an internet connection. So far its going really well. I am using Server.Execute to get the content for each page, then putting it in static html pages and changing the dynamic links to static html links (ie changing all aspx links to htm). I am able to output all the pages for about us, contact us, home, and the entire catalogue. However, one of the stylesheets which is included in the page based on the URL (if the page is in the administration section then it is not included, otherwise it is) is not being included in the pages when it should be. I have tried outputting the URL but it just returns the URL of the calling page, not the page being called.
Simple mvc page with a few controls that includes a validation summary area.
Once the fields are completed there's a download button.
If I enter something invalid, as expected, my controller code updates the UI with the appropriate error. However, if I then correct the error, and then click the download button a file is downloaded, but the UI never gets updated - presumeably since there's no update on the view.
