The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

set up a proxy page in asp.net web application

I have an asp.net web application and another internal asp.net website (not open to public) deployed as a rest service.
I want to create a proxy page in my public asp.net application , such that, say
(example contrived for the questions)

when a get request is made with a url parameter -- > http://ck.com/myproxypage.aspx?queryparameter=somevalue,
depending upon the queryparameter, i call internal rest api, and forward the response to the caller.

the response from the api, could be one file, or multiple files such as html, js and css files. it can be just a pdf file .
how would i get the response from api and forward all the content to the caller?

Hi there!

The code presented in my last post here:

https://www.experts-exchange.com/questions/29113749/Sending-E-mail-through-GoDaddy.html

works as expected, but I have to click a button to "make it happen".

What I really need is to call this page from another, so that it goes through the code, sends the email to the user, and goes to another page immediately.

I have tried to adapt my previous code, but it does not work. Error message:

-------------
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: BC30451: 'txtTo' is not declared. It may be inaccessible due to its protection level.

Line 8: lblMsg1.Text = ""
Line 9: txtTo.Text = " ... "
Line 10: txtFrom.Text = " ... "

Could you please check the code below and tell me how should it be corrected?

Sending E-mail through GoDaddy

Hi there!

The code below is all there is in a asp.net vb page, that is called when the user must receive an e-mail with registration data.

I am not familiar with asp.net , therefore I created the page based on some googling...

It doesn´t work, but I believe (and hope) the error is simple. Could someone change it to make it work?

Thanks,
fskilnik.

What is the difference between ASP.NET Web Application Visual C# (.NET Framework) and ASP.NET Web Application(.NET Framework) Visual Basic when it comes to developing a web page. I am trying to convert a desktop VB6 application and want to start off on the right ASP development page. I am in the process of learning Visual Basic again.

Also, I see a .NET Core version, so what exactly am I looking at as this can be quite confusing as to where I should begin?

C# server side click event for html button

On my page Default.aspx

On this page Default.aspx.cs

The server side click event for the button is this:

protected void Button2_Click(object sender, EventArgs e)

If I have a html button like this on this page Default.aspx

<input id="Button1" type="button" value="button" />

On my DevExpress ASP.NET Web Forms project hosted in Azure I have a XtraReport which prints fine on my development system and also tests OK at a company where I consult but my client, an administrator at a national construction company gets an Acrobat Reader error when the report is rendered to PDF and can't view or print it.

She has asked her IT support to help but they may turn round and say it is down to my Web App.

Do you have any suggestions as to what is going wrong here?

I have a WebForms legacy application. When I run it in Visual Studio from any page other than login.aspx, I can never login. The execution comes to login.Page_Load(), but never reaches login.Submit_OnClick(). And I stay at the login screen. If I start the application from the login.aspx, everything works as expected. Could you please give me any idea on what is wrong? The application works on my machine's IIS. But if I run it on the server using VSTS, it works only if I explicitly enter url with /login.aspx.

Hi experts,

I saw this working ASP.net example:

https://www.c-sharpcorner.com/UploadFile/1e050f/edit-and-update-record-in-gridview-in-Asp-Net/

In that example when when you click on edit link of a row in the GridView, then all the items in the row become editable and then if you edit an item in the row you can then press the update button and it will update the record.

How can I revise that example to the following?:

on page load , show every row in the Name column in edit mode.
Then, above the GridView grid put a button that says Update.
So if I edit any of the names in any of the rows and then click that update button it will update the names I edited.

To summarize,
instead of having to click on each row one at a time and then update a name like the above example currently does, I just want to have the GridView launch with all the records in the Name column in edit mode, so I can simply make a Name change and then just click an update button one time to update the multiple names I edited.

I am converting my VB6 desktop app to VB.NET and ASP.NET so that I can "webify" the application I have. What is the best way to begin learning? I downloaded and installed the Community Edition of Visual Studio. Should I start googling ASP.NET first or VB.NET first? How will this actually play out? Will I end up having to learn both at the same time since they are tied? What exactly is the relationship between the two?

Also will I need to know HTML and any other languages? At the end of the day, I am only looking to convert about 6 screens in my VB6 app to .NET so that it can be accessed from more users and even Mac users.

Thanks

Telerik RadWindow passing parameter

Hi experts,

I'm using the Telerik UI for ASP.NET AJAX RadWindow.
https://demos.telerik.com/aspnet-ajax/window/examples/overview/defaultcs.aspx

I'm using ASP.NET and VB.

I saw this example here for passing a parameter from the Main page to the RadWindow:

Using RadWindow as a Dialog
https://docs.telerik.com/devtools/aspnet-ajax/controls/window/how-to/using-radwindow-as-a-dialog

I recreated this example and it works fine.

This is the working code:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="RadWindow1_MainPage.aspx.vb" Inherits="RadWindow1_MainPage" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

            var txtInput = document.getElementById("txtInput");
            sender.argument = txtInput.value;
        }

I have a net 2.0 compact framework client that pulls data via an asp.net web service (also 2.0) . This is working fine until we try to connect to the web service on an encrypted link
https: Now I'm getting a web exception in the client, it does work if I change it back to http:

Is there something I need to put in the local.config file to support https? Something with the certificate I need to change or something else

Im getting started to learn VB.NET and ASP. I am coming from a background with some experience in VB6.

What software tools do I need in order to develop a webpage with VB.NET and ASP? Do I need a specific web server from Microsoft? If so, what version? Do I need Visual Studio? If so, what version. What is needed to begin setting up ASP? Is that automatically built-in to the web server?

Also, what is the difference between ASP and ASP.net, if any?

Thanks

I am trying to use HttpClient in C# as below:

{
         handler.UseDefaultCredentials = true;

         using (HttpClient _httpClient = new HttpClient(handler))

I understand that HttpClientHandler has "UseDefaultCredentials" property.
so what is "UseDefaultCredentials"?
And if "UseDefaultCredentials" is set to true, what does that mean?

ASP.Net MVC 5

I am trying to fetch the result from Jquery to my controller.

However, in my controller - ActionResult is not invoking. What could be the reason ?

[HttpGet]
public ActionResult ActionName(string id)
{
// do something
var vm = id;
return View(vm);
}

JQuery Syntax :

$('button').click(function () {
var btn = $(this).attr('id');

alert(btn);

$.ajax({
type: 'GET',
url: '@Url.Action("ActionName", "ControllerName")',
