C# - Using AJAX To Run A Webservice In The Background
Apr 20, 2011
I basically need to do this, but unfortunately my hosting provider doesn't give me "Full Trust" so I can't run threads. Is there a way to do this using AJAX?
//Updates Information in Database
Thread threadFind = new Thread(LoadFind);
threadFind.Start();
Response.Write("Send old information to users"); I don't want my users to have to wait at all for a response, so I can send them the old information. However, while they are on the page I want another thread (or something that works like a thread) to update the information for the next user that visits.
I don't want to use a webservice to populate an autocomplete extender on a textbox. In this case, it's where the user is entering email addresses and I don't want to make a trip to the database every single time. I'd much rather keep a collection in session state and 'bind' the autocomplete to that.
Is it possible to set ServicePath and/or ServiceMethod to something in the codebehind as opposed to a webservice?
I am using query from a SQLite database as the AutocompleteCustomSource for a ComboBox. Also, I want to load data in separate thread. My LoadData method works fine when called directly, but it fails when it is called from the BackgroundWorker thread. When it is called from the background thread, it throws a Specified cast is not valid exception on the csearch.AutoCompleteCustomSource.Add(hh("Taj")) line. Below is my code:
Sub LoadData() Dim connetionString As String Dim cnn As SQLiteConnection
I have to send a request to Webservice and I have a working PHP solution, that I have to translate in VB.net
Here's the code working in PHP
//fill in the details of the contacts.userId is obtained from loginResult. $contactData = array('lastname'=>'Valiant', 'assigned_user_id'=>$userId); //encode the object in JSON format to communicate with the server.
[code]....
Naturally I imported a reference to a Json library and Imported (Imports Newtonsoft.Json)?
what I am trying to accomplish worked with the code in the last thread I posted a while back. I still am using this code, however, I changed the window size to work better and gave it a nicer background for the title screen of my project. Now what I am working on at the moment is making a settings form that has 2 labels. One for "Default" Layout and one for "Plain" layout. When default is at start, the default label is disabled,and when plain layout is clicked, the button is disabled and default button is enabled.Basically, this is a toggle switch for default or plain where if one is enabled, the option for it is disabled and the other is enabled.My problem is that when I switch from Plain back to default, the background Image will not switch back from the plain background color of "control"Here is my code:
Public Class Settings Private Sub LinkLabel1_LinkClicked(ByVal sender As System.Object, ByVal e As System.Windows.Forms.LinkLabelLinkClickedEventArgs) Handles LinkLabel1.LinkClicked MiDNiGHT.BackgroundImage = Nothing[code].......
we had developed a webservice in vb.net,framework 2.0. We would need to rewrite this websevice in WCF with framework 3.5. Please provide some guidance regarding this and also there are many othersystems consuming our webservice url. Will this conversion have impact on the source system or does it involve any build activity for the source system to consume the url that will be developed with WCF method?
I have a search engine that will use a webservice to search through my database to find 3 specific things. I don't even know if it will work like this, but I have a dropdown list on my main page to select Product, Feature, Description. From what the user selects, the webservice should then go to an if statement to use the correct SELECT statement and find results for the search.
Will someone help me figure out how to fix what I've written to make it work? Please don't be too critical, I don't have a lot of experience. I have also been researching SQL Injection because I have a lot of code that is vulnerable so keep that in mind when you look at my code.
I can't get the blue squiggly lines to go away that are underneath the DropdownList1.Value instances on the WebService page.
WebService:
<WebMethod()> _ Public Function GetCompletionList(ByVal prefixText As String, ByVal count As Integer) As String() Dim Feature As String = DropDownList1.Value Dim Description As String = DropDownList1.Value Dim Product As String = DropDownList1.Value
[CODE]..........................
Default.aspx page - Here I need the dropdownlist to tie to the database somehow.
I am trying to get subsonic to run work in a webservice I am not sure how to return the data. I only get the word Object in my results when It return anything instead of values. What am I missing?
<WebMethod(Description:="Method to retrieveCptCode subsonic List")> _ Public Function GetSubCptCodes() As CPTCodeCollection Dim coll As CPTCodeCollection = New CPTCodeCollection() Dim qry As Query = New Query(CPTCode.Schema) coll.LoadAndCloseReader(qry.ExecuteReader()) Return coll End Function
I am invoking a webservice and got this error..Do anyone know what is the exact problem..System.ServiceModel.Security.MessageSecurityException: An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail. ---> System.ServiceModel.FaultException: An error occurred when verifying security for the message.
Is there an easy way to schedule a webservice that was created in vb.net. Would I need to create a .asmx file or do I create an executable in vb that calls a webservice?I have created a webservice using SOAPUI 3.6.1. would it be easier to schedule that instead of creating a vb app.
I created a website that contains a Webservice that transfers data to a windows application Using a collection, however, I get this Error that says that anything that inherits the ICOllection, it must implement Add(System.Object)
Writing a VB app that uses a webservice. The URL for this webservice will change based on where the app is running from so I need to change it at runtime. I see that by default the web reference URL has its behavior set to "Dynamic" which means I should be able to change it at runtime, but at the same time the app.config file has the Scope set to "Application," which means it's read-only at runtime. I'm looking to use My.Settings.WebServiceURL = "new url" but in order to do this the scope has to be set to User... I think. But if that's the case then what does the "Dynamic" behavior do for me? Can someone give me a code example of how I can change this at runtime?
I am using a PropertyGrid control. There are two things I need to be able to do.
1. I need to be able to access Ajax controltoolkit components and populate the propertygrid with the properties from the Ajax control toolkit.
2. I need to be able to do the same with WebUI components.
The basic part, populating the propertygrid with a control, I understand how to do - -
What I don't know is what to import or how to access what dll (for the Ajax Control Toolkit and the Web UI controls), in my Winforms project to be able to do this.
In my project I have a view model City that is exposed by wcf. One of the properties is named differently then the already exposed contract dictates. Therefore I added the DataMember attribute and set the Name value like so:
<DataContract(Namespace:=ServiceNamespace)> _ Public Class City private mySelectedTranslation as String
I have a .exe program which has an embedded webservice running on port 800.I can access it locally via 127.0.0.1:800 just fine once the program is executed.I need to be able to send the service commands such as: * 127.0.0.1:800/dev * will get a list of devices attached to the program.
To my knowledge i need to forward port 800 on my router and then access my internet IP externally and I should be able to view/access this web service? am i correct?I am then wanting to create a PHP site which will send the desired commands back to the web-service running on my home pc.
Well im working agains a webservice that has a certificate that is not 100% correctly setup the certificate is setup for the domain [URL] and the api is located at [URL] now i cant connect to this webservice as i then get a WebException "Could Not establish trush relationship for the SSL/TLS secure channel. The remote certificate is invalid according to the validation procedure. Now my question is there any way to bypass this check i use a normal Web Reference (2.0) not a Service Reference..
I am currently developing an application using VB.NET in which I am using the REST WebServices. I have been able to do the basics with REST, however, I have not been able to add an attachment (more specifically upload a file, using REST which gets attached). I have done extensive research online, but so far I have not been able to find any working examples in VB.NET. To actually upload the data I use System.Net.WebClient. The following VB.NET code does the important work:[code]As you can see, the postString is converted to bytes and then uploaded to the server. However, I do not know where or how I should be posting the raw attachment itself. The documentation for the service we are specifically using states to use a variable "attachment_ 1," which I added to the postString variable, but I am not sure what the next step should be. Should the file be converted into bytes and appended to the postBytes variable?
i have a website and i want to download a file from another folder on the same server. I want to use webservice, which i am not very familiar with. How can i download that file by pressing a button on my website, using webservice?
From desktop application I want to upload an image. Then want to pass that image to webservice which encrypt it and pass it to another webservice which will save the encrypted image in the Access database. And then using ASP.net want to decrypt the image.
I did a search first - so if I missed it just let me know. I want to run an application using windows scheduler and use a certain username and password. The application will then call a web service. I need the wed service to run as the username and password used to run the application. Then I need to perfrom a DB connection with the same username and password.
I have looked at impersonation but not getting it all the way.
I have to return a lot of values back to my windows application from my webService. But how would I return more than just a single string/int/boolean from my WebService to myApplication. How would I return a collection, keyValuePair, or even better, a DataSet? Or is this just imposible?
I have a webservice with a webmethod that accepts an XML from a client via POST (don't know if this really matters), validates XML and the data inside, and then processes the XML and returns an answer to the client.At moment, I have a problem with large XMLs; it takes too long for the XML preprocessing to finish, and the clients timeout expires.Instead of increasing the timeout of the client I thought I could maybe separate the XML validation from the XML processing by starting a new thread after the validation which processes the XML and at the same time return the validation answer to the client. (the processi
