I did the web method below using C#. I'm tryin to convert this into VB.NET, but I'm missing something. I'm using it with an ajax calling, from a paginator/sorter table plugin.
[WebMethod( EnableSession = true )]
public static object listaPessoas(int jtStartIndex = 0,
int jtPageSize = 0, [code].....
Second, I don't know how to return the message "OK" and the list of people.
I have an ASP.NET C# project consuming webservices and WebMethods are wrote in VB.NET with source code on a local IIS server. The WebMethod returns null, and I want to debug it to know why I get this.
View 2 Repliesmy code calls a WebMethod. Within that WebMethod I have the need to create a new control collection. In VB I would normally write:
Dim cc As System.Web.UI.ControlCollection = CreateControlCollection()
But because I'm inside a WebMethod, I get the error :
Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.

I'm trying to eliminate a VB.NET button on my aspx page. Trying to use javascript and ajax to execute the same code my vb had.I put in a script manager, set EnablePageMethods to true, added a static subroutine, and referred to it in my javascript function (BTW -- this seems a lot of work just to execute an existing subroutine). The javascript calls my code-behind and it almost works.Problem is, now I'm getting a NullReferenceException when SimulatePrintBatchClick tries to do anything with the controls.
Error is 'Object reference not set to an instance of an object', line is 'pnlVars.Controls.Clear'
Here's the code from UW.aspx:
<WebMethod()> _
Public Shared Sub PrintBatchFromJSWM()
Dim UWI As New UW
[code]....
when I run the above code in PrintBatch_Click it all executes just fine. I really don't understand why it bombs out as a subroutine.
Perhaps this is not the way to do this, but I'm at a loss for finding a different way. Originally this code was handled by an ASP/VB button, but the specs have called for it to be deleted.
I am using an ajax PageMethod to call an asp.net webmethod. From there I'm trying to pass a lot of XML back to a callback javascript function.
Currently I just convert the XML into a string and pass it in that format. But it seems that if the string is too long it causes an error.
[Code]...
So my question is: Is there a better way to pass the XML from VB to javascript, or a way to allow large strings to be passed without error?
In a page to create new user accounts, we have a database with a little of allowable users. To streamline getting the Email address of the new user correct, we want to use an AutoComplete extended textbox.Now I know that WebMethods are working because I have a cascading-drop-down tied to web methods in another page.As I'm just starting on this page, the code is simple.The page itself:
<cc1:ToolkitScriptManager ID="ScriptManager2" runat="server"/>
<p></p> Please enter new user's Email:
<asp:TextBox ID="txtUser" runat="server" />
<cc1:AutoCompleteExtender runat="server" ID="autUser" TargetControlID="txtUser"

I'm not even getting to the LogDebug statement. I've used all the same boilerplate code (Inherits, the 'WebService' tags, etc) that worked in the other WebMethod with the appropriate changes to the Class name but this really has me stumped.
I have a VB.NET function which looks like this:
<WebMethod()> _
Public Shared Function AuthenticateUser(ByVal UserInfo As String, ByVal Password As String) As Boolean
Dim UserName As String
[code]....
It calls the function, but won't return a value. When walking through the code, my VB function does fire (it will return true so long as the correct password is typed in), but the javascript 'authenticated' value remains 'undefined'. It's like you can't return values from VB functions to javascript.
I also tried
if PageMethods.AuthenticateUser("UserName", "Password")
{
//Stuff
}
But still no luck.
I'm developing a website with ASP and VB.NET 4. I'm also using the FullCalendar jQuery plugin, but I have a trouble: catching a parameter from querystring to the webmethod in the .asmx. I've tried to refer the querystring property with the Request.QueryString() and it doesn't work.
Here's the webmethod:
<%@ WebService Language="VB" Class="wbsCalendario" %>
Imports System.Web
Imports System.Data
[Code].....
I'm trying to use an auto-complete, and it works fine if I call a function without a parameter in the web service:
<WebMethod()> _
<Script.Services.ScriptMethod()> _
Public Function GetCompanyNames2() As String()
[code].....
I have a Web Service with one WebMethod for which return value is boolean.It accepts XML file as string and process data. How can I first return status as true and then call the ProcessData method.
As the processing data takes time I need to return true first and then process the data.
[webmethod]
Public function receiveData(ByVal xmlstr as string) as boolean
dim status as boolean=false
try
[Code]...
when calling a webmethod
[WebMethod]
public Profile synchronize(string MID, DeviceUploadData data)
The object DeviceUploadData has many properties, and a few of them are array's. My question is about the array specifically. It loses it's value once it's received on the webmethod end.This is the property inside DeviceUploadData
Private data() As DataObject
Public Property Data() As DataObject()
Get
[code]....
So the DataObject is populated with data, then once passed, on the other end, some of the DataObject properties are no longer populated. I haven't included the other properties in this example.
I have a WebMethod that recives HTML as parameter somthing like this:
Public Function ConvertHtmlToPdfListAnswer(ByVal dokument As Dokument) As Byte()
In this HTML my path to for example user signature looks like this:
Handlers/SzablonyListImgHandler.ashx?usid=2006
My handler starts like this:
Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
and it takes parameter from context, creates query for databese and returns stream output like this:
If Not String.IsNullOrEmpty(context.Request.QueryString("usid")) Then
...
...
streamOut.WriteTo(context.Response.OutputStream)
My problem is that it fires onle once...what I mean is that when I call the service again it doesn't enter the handler but it already shows me the image when i check the HTML in debugger view. So when The user changes his signature in database the service method still returns the previous one...
Getting sick with asp.net permission, This time, I Just cant AJAX-CALL any kind of webmethod or i just get: Message":"Authentication failed.

I have 2 forms. Using Visual Basic.On Form 1 there is a populated combo box. This was done so by running a query through it and populating it with PUZ_ID values from a data set.On form two there is a tool strip and below is a search query.I need to be able to select the value i want in the combo box on form 1, and launch a button that opens form 2, which has loaded the data that i binded onto the form.Anyone have any ideas/code or need me to clear this up a bit more?So i need to run something through a query, or make something public or what?

I would like to have custom methods to pass data between function, or to keep it in memory throughout the program.
Example:
Private function info()
Addr1 = addr1.text
Addr2 = addr2.text
City = city.text
[code]....
Could I run this function towards the beginning of the program and use it throughout until the form is disposed? I can't seem to get the information to stick once I get out of the function, I will need to use the same information multiple times throughout the application so I figured if I could make a function to keep the info rather than declaring the 5 lines in every option but anytime I call the method, it fills it correctly then when I get back to the main function the info goes back to 'nothing'. is it possible to pass data around between functions like you could in Java?
