WCF / ASMX :: Increase The Timeout Of Webmethod Call?

Mar 25, 2010

In my web app, if user clicks a button, I have to kick off a long running task. I have to keep the user informed about the status of execution of the task from time to time. To accomplish this, I create a thread on button click which makes a synchronous webservice call. The webmethod works on a long running task; while the main thread informs the users about the status of execution.

Currently the webmethod call times out in approximately 90 seconds. I want to increase the timeout to 10 mins. I tried setting <httpRuntime executionTimeout="600"/> along with debug="false"; but in vein. Can anyone tell me what I am missing?

Pass Optional Parameters Into A WebMethod Via JSON?

Feb 15, 2010

I have the following JSON class I am intending to use to perform management calls on my database asynchronously:

<script type="text/javascript">
var CalendarManager = {
defaultOptions: {
staffcode: 0, // required
date: 0, // required

[Code]....

Basically, my question is: how do I specify optional parameters to a WebMethod when providing JSON data?

I know I can reduce the parameters down to just the required values, and then use HttpContext.Request.Params to read the values of optional paramaters, but I would have thought the way I have tried here should have worked.

EDIT

The XMLHttpRequest.responseText value for the error is:

Invalid JSON primitive: staffcode.

This is throwing me even more off the scent of the problem :(

Using Both Post And GetAjax Calls For The Same WebMethod In ASMX Web Service

Jan 20, 2010

I can't seem to call a web service method from Ajax with both POST and GET.

Initially only the POST would work and GET would causes this error:


{"Message":"An attempt was made to call the method u0027getDatau0027 using a GET request, which is not allowed.","StackTrace":" at System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext
context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}

I fixed that by adding this attribute: [ScriptMethod(UseHttpGet=true)] but now GET causes this error:

[code]....

So is it true that you can only use either POST or GET and not both from Ajax?

WCF / ASMX :: Web Service - WebMethod Accepting Custom Object?

May 11, 2010

I have a custom class declared as follows (in vb.net)

<Serializable()> _
Public Class NumInfo
Public n As String
Public f As Integer
Public fc As char()
Public t As Integer
Public tc As char()
Private validFlag As Boolean = True
Public Sub New()
End Sub

I also have public properties(read/write) for all the public variables

End Class
In my service.asmx codebehind class I have a webmethod as follows:
<WebMethod> _
<XmlInclude(GetType(NumInfo))>
Public Function ConvertTo(ByVal info As NumInfo) As String
Return mbc(info)
'mbc is another function defined in my service.asmx "service" class
End Function

The problem is that when I start debugging it to test it, the page that I get does not contain any fields where I could input the values for the public fields of numInfo. How do I initialise the class? There is no "Invoke" button either. All I see are soap details as below:

ConvertTo
Test
The test form is only available for methods with primitive types as parameters. SOAP 1.1 The following is a sample SOAP 1.1 request and response. The placeholders shown need to be replaced with actual values.
POST /BaseConverter/BaseCon.asmx HTTP/1.1
Host: localhost
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://RohitServices.in/ConvertTo"
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<ConvertTo xmlns="http://RohitServices.in/">
<info>
<n>string</n>
<f>int</f>
<fc>
<char>char</char>
<char>char</char>
</fc>

What am I doing wrong? For the record I tried replacing char() with string to see if it was the array causing problems but that didn't help either. I'm fairly new to web services. I tried replacing the custom object parameter with a primitive parameter just to check how things worked and it rendered a page with an input field and invoke button. I just can't seem to get it working with custom object.

AJAX :: How To Pass More Than One Control Values To Webmethod For AutoCompleteExtender

Apr 5, 2010

I am developing a user control. This user control is having 2 Dropdown controls and one textbox('txtCustomer'). I am using autocompleteextender for the text box. This 'txtCustomer' control populates the data based on the value selected in 2 dropdowns.

I need to pass the selected value of this 2 dropdown to my meb method. I am not using web service(.asmx page) for this application instead i am using page level web method. I tried to access the controls from the web method inside the Page. but all the identifiers and controls of the page returning null in the web mothod. I have analysed it is because the events "page_Load and page_Init" are not getting fired.

AJAX :: ASPX WebMethod Not Running The WebService Webmethod Returning The Page?

May 19, 2010

I have a service that works great on my development box. It uses JQuery to hit my web service, and then the JSON results are sent back.

The web service is located on our basePage.cs. We didn't want to put out an external WebService for this. Our on beta box something different is happening.

The web page seems to be trying to call the web method correctly - the JSON data is being sent... but the server doesn't seem to know it's a webmethod. here's my service function (it's in our basepage.cs which inherits from Page).
