I have a custom IHttpHandler which is used by thick clients to download files using a url such as
http://url.ashx?id=123&version=456
the code handler basically ends with context.Response.WriteFile(myLocalServerPath);
Is it possible to replace this using the typical asp.net mvc controller pattern ?
I have some xml data. I've made an asp.net soap based webservice that takes the xml as a byte buffer applies xsl transformation to it and converts it to a docx file. But when i return the docx file using the response object i get an error that client found response of type application/vnd-word but it was expecting text/xml.
Service Snippet to push document file after xsl transformation
Context.Response.Clear();
Context.Response.ClearHeaders();
Context.Response.ContentType = "application/vnd.openxmlformats- officedocument.wordprocessingml.document";
Context.Response.AddHeader("Content-Disposition", "attachment; filename=" + "test.docx");
Context.Response.Flush();
Context.Response.End();

View 5 RepliesI'm using the System.Diagnostics.Process class to run a batch file. I need to be able to take an output from the batch file and then display it on the web-page, basically to know if it succeeded or not, since the batch runs an .exe that doesn't always succeed.
the values returned by the .exe and have the batch run a script depending on the value returned. The script could be a VBscript that sends info to the webpage, but even then I'm not sure how to accomplish this.

View 1 RepliesI've been reading quite a few tutorials on web services and xml files and one thing isn't quite clear to me. If I want to create an XML file on the fly the tutorials are pretty straight forward but, I want to grab an existing XML file from the web server and return the whole thing. Do I need to read the XML file and send each individual node or is there a way to send the file all at once? The tutorials imply that the whole file could be a node but I'm not clear on what that entails or if it would work. Also do you have a link to an example?
View 1 RepliesI have a simple asp.net form that has a textbox that collects phonenumbers to send SMS messages. If I bypass the form and hardcode the numbers using the following format:
"2133211234",#1233211234"
the code works fine. However when i try to use this same format using my form, the sms will ONLY send to the first number. I have a feeling i'm missing out on some property on my form that will accept all of the values. how how i can add some lines of code that will allow users to enter numbers like this:
3123211234,4123212344 and have it converted to the format above when the number is submitted?

How is it possible to return some kind of list from a WCF service, this the method in my WCF service.
My interface:
[OperationContract]
[WebInvoke(Method = "GET",
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Wrapped,
UriTemplate = "Locations")]
IList<Location> GetLocations();
public IList<Location> GetLocations()
{
Pazar.Data.Repositories.LocationRepository locRepository =
new Pazar.Data.Repositories.LocationRepository();
return locRepository.GetRootLocations().ToList<Location>();
}
and this how my GetRootLocations looks like, It returns IQueryable, I wonder if I can maybe return IQueryable from my WCF service?
public IQueryable<Location> GetRootLocations()
{
IQueryable<Location> locations = GetAll().Where(p => !p.ID_Parent.HasValue).OrderBy(p => p.Sequence);
return locations;
}
I have created alot of stored procedures in my application that return the result of a query in a datatable object. I never use a dataset. Why would I ever use a dataset over simply returning the result of a query as a datatable object?
View 3 RepliesI have a problem with getting jquery to retrieve results from a WCF service. I am hosting the WCF service within IIS and when I attach the debugger to this process I can see that the code is processed successfully. However, when it hits the callback within jquery there is no data??
I have set up a trace on the wcf service and there are no errors. It just seems as though the data is lost after the wcf service method completes.
Here is the jquery code which calls the service:
$.get("http://ecopssvc:6970/ecopsService.svc/Echo", {echoThis: "please work"}, function(data) {
alert("Data Loaded: " + data);
});
Here is the wcf config:
<system.serviceModel>
<services>
<service name="EcopsWebServices.EcopsService" behaviorConfiguration="EcopsServiceBehaviours">
<endpoint address="" behaviorConfiguration="WebBehaviour"
binding="webHttpBinding" bindingConfiguration="" contract="EcopsWebServices.IEcopsServiceContract" />
</service>

<serviceMetadata httpGetEnabled="true" httpGetUrl=""/>
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
Here is the service contract:
[ServiceContract]
public interface IEcopsServiceContract
{
[WebGet]
[OperationContract]
string Echo(string echoThis);
}
Here is the Service implementation:
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class EcopsService : IEcopsServiceContract
{
#region IEcopsServiceContract Members
public string Echo(string echoThis)
{
return string.Format("You sent this '{0}'.", echoThis);
}
#endregion
}

I'm saving military time into the database. Then I need to pull this data back out of the database. To get just the time without the date I can do this: String.Format("{0:T}", pullsaved.First.timeValue) But this returns a six digit time, e.g. 100000 (HHmmss). But I want it to return just HHmm (1000). I tried the following, but it didn't work. DateTime.ParseExact(String.Format("{0:T}", pullsaved.First.timeValue), "HHmm", CultureInfo.InvariantCulture)
