I have a ASP .NET MVC project, inside controller, I call a simple WebAPI using WebClient
e.g.
WebClient client = new WebClient();
client.Headers.Add("cache-control", "no-cache");
client.Headers.Add("accept-encoding", "gzip, deflate");
client.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
client.Headers.Add("Accept", "application/json");
client.Headers.Add("Authorization", "Basic xxxxxx");
var respond = client.UploadString(new Uri("https://xxxxxx/"), "POST", "xxxxxx");
there is an exception when call UploadString immediately with error
"The entry '*' has already been added." in webConfig.
If remove the line "<add address="*" maxconnection="500"/>" from webConfig, the
exception is gone. Same thing is also happen when using HttpClient and RestClient.
WebConfig
"...
<connectionManagement>
<add address="*" maxconnection="500"/>
</connectionManagement>
..."
Do anyone know why it happen? Why does WebClient attempt to add the entry to configuration
during runtime and cause the error?
BTW, I have fixed the problem by remove the line from WebConfig, and put it to program StartUp
e.g.
System.Net.ServicePointManager.DefaultConnectionLimit = 500;

It's likely that the configuration from a higher level already defines the * address. This could be in a config file from a parent application, or the machine-level config file.
The simplest option is to clear or remove the addresses before adding the new one:
<connectionManagement>
<remove address="*" />
<add address="*" maxconnection="500" />
</connectionManagement>

I have dynamic data showing on a blazor page
@foreach (var item in DisplayList.OrderBy(i => i.CompanyId))
{
<tr>
<td style="width:300px; color:darkgreen;">@item.Company</td>
<td style="width:250px; color:blue;">@item.FunctionName</td>
<td style="width:250px;">@item.Identifier</td>
<td>@item.SkillsSet</td>
</tr>
}
In my code I do a if..contains..replace on the part item.SkillsSet.
This is a string.
What I'm trying to do is: when this string contains a value I want that value to be surrounded with the "mark" tag so that part is highlighted.
Like: Jo | Lisa | Me | John
But the result is not what I expect. It shows the names and the tag. It doesn't highlight the text
It shows:
Jo | Lisa | <mark>Me</mark> | John
What to do?
|
|
|
|
|
Try using the Html.Raw helper method to indicate that the string should not be HTML-encoded:
@Html.Raw(item.SkillsSet) NB: You'll need to make sure the rest of the string is properly HTML-encoded to ensure it displays correctly and to avoid the potential for a persisted cross-site scripting vulnerability.

So have I have a modal with a updatepanel and a repeater inside it. I have an open another modal on linkbutton click, I would like to update the 2nd modal with a checkboxlist, but the linkbutton click doesn't fire for me to update the 2nd modal data.

There's a secret error somewhere in your secret code. You should fix that.

document.activeElement.id is not working in safari
|
|
|
|
|
If you wish for help with your problem then you need to edit your question and provide full details. Saying, "not working", tells us nothing.
|
|
|
|
|
Hence, you can change your event handler from:
$('#modalLogout').on('hide.bs.modal', function () {
var activeElement = $(document.activeElement);
to the delegated one:
$('#modalLogout').on('click', '#LogoutOk', function (e) {
var activeElement = $(e.target);

You'll probably want to start with the Media Capture and Streams API[^]. But that's an extremely ambitious project, especially for a beginner.
NB: Asking for help writing something without explaining precisely what help you need, what you have tried, or where you are stuck, will lead people to assume that you want someone to do all the work for you. That's not going to happen.

Can you please help on the best approach to build an API in JAVA/Dotnet which has mainframe as database.
Basically we need to expose product data information so that consumer can use them for their business analysis.
|
|
|
|
|
Exposing production data for analysis is fraught with nightmares. Business analysis is a monster and should only be done against a data wharehouse so the first thing you need to look into is wharehousing strategies. They will depend on your data size, replication speed requirement and budget.
Once you have sorted that then connection to the wharehouse is trivial. Designing the wharehouse on the other hand is an entire career.

suppose i am developing a site with ASP.Net MVC core. i have created a empty project where i add two controller.
one is Home and login controller. Home controller's index action is not protected by Authorized attribute but Home controller's product action is protected.
when user try to access product action then user should be redirected to login page if not signed in. so tell me how to setup project in classic mvc or mvc core where i will mention that user should be redirected to login page if user is not signed in.
i will not use identity rather i will check user credentials from db using ado.net.
please guide me step wise that what i need to follow. Thanks

Sir, my question was bit different. i am trying to know how asp.net mvc engine understand now user need to redirect to login page? if login controller name would be different then how asp.net mvc understand it ? where this binding done in default project when we create a default project from IDE?
i believe there must be a place where we mention that login page should come if user is not signed in when access any protected resource.
please share knowledge if you know. thanks

Please see the code.
using (Html.BeginForm("Login", "Default", new { ReturnUrl = ViewBag.ReturnUrl, data = Request.QueryString["data"] }, FormMethod.Post,
new
{
id = "idtest1",
onsubmit = "this.querySelectorAll('button').forEach(i => i.disabled = false)",
@class = "form-signin",
role = "form"
}))
{
}
specially see this line which is not clear to me. onsubmit = "this.querySelectorAll('button').forEach(i => i.disabled = false)",
in the above code BeginForm html helper has been used to render form at runtime. what will happen when form will be submitted ?
what this line will do when form submit ? onsubmit = "this.querySelectorAll('button').forEach(i => i.disabled = false)",
please help me to understand this JavaScript code objective when form submit. Thanks
