I following this article. Everything works great - from a browser.
What we're really after is to use SignalR in a WPF app, so during development I had been hosting in a Console app. Now, I want to host it in IIS.
For testing, I took this sample app and hosted it in IIS on our server. Like I said already, I can chat using from browser to browser.
Now, I'm trying to create a Console app that calls the Send method on the server from my PC:
class Program
{
private const string HUB_NAME = "ChatHub";
private static IHubProxy HubProxy;
static void Main(string[] args)
{
try
{
string url = "<a href="http:
var connection = new HubConnection(url);
HubProxy = connection.CreateHubProxy(HUB_NAME);
HubProxy.On<string, string>("send", HandleSendResponse);
connection.StateChanged += Connection_StateChanged;
connection.Error += Connection_Error;
Console.WriteLine($"Connecting to hub named '{HUB_NAME}' at {url}");
connection.Start().ContinueWith(task =>
{
if (task.IsFaulted)
{
Console.WriteLine("Connection failed");
foreach (var ex in task.Exception.InnerExceptions)
{
Console.WriteLine(ex.Message);
}
}
else
{
Console.WriteLine("Connection succeeded");
}
});
}
catch (Exception e)
{
Console.WriteLine("EXCEPTION OCCURED" + Environment.NewLine + e.ToString());
}
Console.WriteLine("Press any key to quit");
Console.ReadLine();
}
private static void Connection_Error(Exception obj)
{
Console.WriteLine($"Connection attempt threw '{obj.ToString()}'");
}
private static void Connection_StateChanged(StateChange obj)
{
Console.WriteLine($"Connection state is '{obj.NewState}'");
if (obj.NewState == ConnectionState.Connected)
{
string[] args = new string[2];
args[0] = "John Doe";
args[1] = "Hello there!";
HubProxy.Invoke("Send", args).ContinueWith(task =>
{
if (task.IsFaulted)
{
Console.WriteLine("There was an error calling Send: {0}", task.Exception.GetBaseException());
Console.WriteLine(task.Status.ToString());
}
else
{
Console.WriteLine("Send Complete.");
}
}).Wait();
}
}
private static void HandleSendResponse(string name, string message)
{
Console.WriteLine($"Server returned: '{message}' from '{name}'");
}
}
I'm getting the exception "You are using a version of the client that isn't compatible with the server. Client version 2.0, server version 1.3."
This looks pretty straightforward, but I've checked twice - both the server and client console app are using SignalR 2.0.0.
In the case of the browser, the jquery versions also look up to date, but my console app should care about that.
I've Googled this and everyone seems ot say the same thing as the message. But from what I can see the versions are correct.
Anyone have any ideas?
If it's not broken, fix it until it is.

I need to install an Asp.Net Web API to IIS on a server as part of another app's installation. We're using Wix to create our installers. During installation of our app, we would also like to put our Web API in IIS on a server.
I see plenty of resources on how to deploy using VS, but how do I do this with an installation package?
How is this done?
Thanks

I'm working in VS2019 on a web project and once in a while this pops up when I go to simply run the code from within Visual Studios..... I know it has something to do with permissions at the URL but in this case I'm running to loacal server from within VS. How can my permissions change like that and what can I do to fix it? Thanks.

Most likely causes:
A default document is not configured for the requested URL, and directory browsing is not enabled on the server.

You probably have it set to run based on the selected document and your selected document is a folder or something that can't be browsed to. Right click a default page and choose to set it as default page.

Quote: everything works but when I try to make it a partial view
Maybe your partial view does not load the scripts that are needed to be there for that fileupload to be defined. Check your browser console to see the actual error, most probably, inside the partial view you need to import the JavaScript for the fileupload component and then call the $(...).fileupload().
This line to be precise,
<script src="~/Scripts/FileUpload/jquery.fileupload.js"></script> If you are sure that you have called this script and it is a part of the DOM, and still this error comes, please share the browser console logs so that we can look into them. You can capture that using F12 and then visiting console (if some other tab is selected).

This is the error that I am receiving :
jquery-3.1.0.min.js:2 Uncaught TypeError: $(...).fileupload is not a function
at HTMLDocument.<anonymous> (script.js:12)
at j (jquery-3.1.0.min.js:2)
at k (jquery-3.1.0.min.js:2)

Can you show the content of your script.js file? The problem comes somewhere from there,
<script src="~/Scripts/script.js"></script> Somewhere at line 12, there is a call to the fileupload function and you can need to make sure that your fileupload script is loaded before line 12 (anywhere!).
One thing that is still bugging me is that why is jquery-3.1.0.min.js in this entire trace. Maybe you are causing a circular (or duplicate) script being loaded. Please verify that each script is loaded only one, and in a correct layout—like your normal view is working out, because this problem comes only in the partial view.
For example, see here for some more insights on the same problem: jQuery-File-Upload - TypeError: $(...).fileupload is not a function - Stack Overflow

Here is the scripts.js file., also how are you identifying that jquery-3.1.0.min.js in this entire trace, I'm just passing the script
<script src="~/Scripts/jquery-3.1.0.min.js"></script>
in the Index.cshtml file which is the view that I am calling in my Details.cshtml.
script.js:
$(document).ready(function () {
var ul = $('#upload ul');
$('#drop a').click(function () {
$(this).parent().find('input').click();
});
$('#upload').fileupload({
dropZone: $('#drop'),
add: function (e, data) {
var tpl = $('<li class="working"><input type="text" value="0" data-width="48" data-height="48"' +
' data-fgColor="#0788a5" data-readOnly="1" data-bgColor="#3e4043" /><p></p><span></span></li>');
tpl.find('p').text(data.files[0].name)
.append('' + formatFileSize(data.files[0].size) + '');
data.context = tpl.appendTo(ul);
tpl.find('input').knob();
tpl.find('span').click(function () {
if (tpl.hasClass('working')) {
jqXHR.abort();
}
tpl.fadeOut(function () {
tpl.remove();
});
});
var jqXHR = data.submit();
},
progress: function (e, data) {
var progress = parseInt(data.loaded / data.total * 100, 10);
data.context.find('input').val(progress).change();
if (progress == 100) {
data.context.removeClass('working');
}
},
fail: function (e, data) {
data.context.addClass('error');
}
});
$(document).on('drop dragover', function (e) {
e.preventDefault();
});
function formatFileSize(bytes) {
if (typeof bytes !== 'number') {
return '';
}
if (bytes >= 1000000000) {
return (bytes / 1000000000).toFixed(2) + ' GB';
}
if (bytes >= 1000000) {
return (bytes / 1000000).toFixed(2) + ' MB';
}
return (bytes / 1000).toFixed(2) + ' KB';
}
});

Hmmm, this looks fine. Just make sure that this partial view is loaded after you have loaded the script. Maybe bring all the scripts up to the top of the body element or at least before this partial view loading.

That didn't fix the issue.

The problem only appears in partial view, right? Not if you keep everything inside the same view.

Hello guys,
I'm trying to do that for a while but nobody is able to help me. (Stack Overflow as well  )
How can I achieve to create images with PHP that look like these Multi Color Gradients? The patterns should defined by positions in the field. It's important that they aren't linear or circled. It needs to be a complex pattern.

Any help would be amazing! Thank you

Quote: Cannot set property 'data' of null
Throughout your entire JavaScript code you are only trying to set the data field of an object in the following codes,
"columns": [
{ "data": "ChargebackCode" },Now, either this is causing an unknown error, or maybe the code causing this problem is somewhere else. Clearly, the object which is being said to be null is an object that you are creating yourself.
One suggestion that I can provide is to set a breakpoint in your browser at the columns field, and then step by step execute the code and see where does this problem occur. I believe, step-by-step code execution can have some answers.

How to perform ajax on Data-table once I click on the check-box.
I already have the ability to auto post-back once the checkbox is clicked, I'm not sure how to achieve this.
View:
<script>
$(document).ready(function () {
$("#DashboardTable").DataTable({
"processing": true,
"serverSide": true,
"filter": true,
"orderMulti": false,
"pageLength": 5,
"ajax": {
"url": "/Chargeback/Index",
"type": "GET",
"datatype": "json"
},
"columnDefs":
[{
"targets": [0],
"visible": false,
"searchable": false
},
{

"searchable": false,
"orderable": false
},

},
{

I don't understand the question. You have code that initializes your datatable when the page loads. Are you asking how to re-load it when you check a checkbox?
If so,
var table = $('#grdTable').DataTable();
table.ajax.reload();

Should I remove this portion:
$(document).ready(function () {
and just add this portion:
var table = $('#grdTable').DataTable();
table.ajax.reload();
|
|
|
|
|
No, that first part initializes your table. The second part just tells it to refresh.
