WCF / ASMX :: Increase The Timeout Of Webmethod Call?
Mar 25, 2010In 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?

View 4 RepliesUsing Both Post And GetAjax Calls For The Same WebMethod In ASMX Web Service
Jan 20, 2010I 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, 2010I 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.
Asmx Webmethod That Uses Mysql Load Data Local Infile?
Nov 16, 2010When I use the following in a webmethod:

VS 2010 - Using Try Catch Inside Of WebMethod
Jul 16, 2011I have a WebMethod that is inside of an ASP.NET Web Service application. I use a Try Catch block inside the WebMethod. If an exception is thrown and I want to see the ex.Message is there a way to use a messsagebox? Maybe there is some Imports statement that can be used so you can use a messagebox inside an ASP.NET Web Service application. I could declare a string for use to display the ex.Message but then the WebMethod would have to return that string somehow. That's something I don't know how to do. As long as no exceptions are thrown I'm ok but if an exception is thrown it's good to know what it is. The ASP.NET Web Service application is using .NET Framework 2.0.
In another thread gep13 was talking about creating a class so that you could return more than one thing from a WebMethod and if that's what I have to do that's fine but if there's a simpler way to see the ex.Message then that's ok too.
C# - Delaying Linq To SQL Select Query Execution
Jun 14, 2010I'm building an ASP.NET MVC site that uses LINQ to SQL. In my search method that has some required and some optional parameters, I want to build a LINQ query while testing for the existence of those optional parameters.
Here's what I'm currently thinking:
using(var db = new DBDataContext())
{
IQueryable<Listing> query = null;
//Handle required parameter
query = db.Listings.Where(l => l.Lat >= form.bounds.extent1.latitude && l.Lat <= form.bounds.extent2.latitude);
//Handle optional parameter
if (numStars != null)
query = query.Where(l => l.Stars == (int)numStars);
//Other parameters...
//Execute query (does this happen here?)
var result = query.ToList();
//Process query...
Will this implementation "bundle" the where clauses and then execute the bundled query? If not, how should I implement this feature?

C# - Creating Instances Of A Class Inside A Static PageMethod Thread Safe?
Dec 14, 2010I am using jQuery to call PageMethods. For certain operations, the current user credentials must be validated and for other operations, I need to call other static methods. Here is some sample code:
Sample #1
[WebMethod]
public static void PostComment(string comment)
{
UserAuth auth = new UserAuth();
if (auth.isAuthenticated)
{
//Post comment here...
}
}
Sample #2
[WebMethod]
public static string GetComment(int commentId)
{
commentDto comment = //get comment data from the database...
string friendlyDate = ConvertFriendlyDate(comment.commentDate);
return friendlyDate + " " + comment.text;
}
public static string ConvertFriendlyDate(DateTime commentDate)
{
string friendlyDate = //call static utility method to convert date to friendly format
return friendlyDate;
}
Will I be safe using these kinds of operations? Am I better to drop page methods and just call a separate ASPX page for my AJAX requests?

My guess is that theres a better way to do this, Am I right?
C# - Setting Private Memory Limit For Application Pool In IIS 7 Increased Page Faults Before Crossing The Limit
Aug 16, 2010I have set Private Memory limit of 200mb in IIS 7 for an application pool. The Private Working Set memory(Task Manager) for the application is always below 125mb but the number of page faults have increased a lot and application cache is getting cleared frequently after setting the limit.
I haven't set any limit on Virtual Memory.why the cache is getting cleared even when the Private memory used is below the allocated memory?
AJAX :: ASPX WebMethod Not Running The WebService Webmethod Returning The Page?
May 19, 2010I 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).
