Excel interop (or any Office interop) is not supported on asp.net. Look at the XML SDK or the Excel ODBC driver.

I know that there are many answers on google, I tried many but nothing worked! I have a CodeMirror text editor and a list of files.I want to display the contents of a file when click on it.This is my first time using Javasctipt so I can't figure out what's wrong with my code.
This is the code I wrote so far:
controller:
public ActionResult Index()
{
StudentsCodes model = new StudentsCodes();
model.Student = (Student)CurrentUser;
var user = UserManager.FindById(((Student)CurrentUser).InstructorID);
model.Instructor =(Instructor) user;
return View(model);
}
public PartialViewResult DevelopmentPartial (StudentsCodes path )
{
return PartialView(path);
}
Main view:
<script type="text/javascript" src="~/Scripts/jquery.unobtrusive-ajax.js"></script>
<script type="text/javascript" src="~/Scripts/jquery-3.1.1.js"></script>
<ul id="tree">
@foreach (var file in Directory.GetFiles(Server.MapPath("~/Content/" + Model.Student.UserName + "/CompilerProject/" + name)))
{
var filename = Path.GetFileName(file);
<li id="filelist" onclick="@(Model.path = "~/Content/" + Model.Student.UserName + "/CompilerProject/src/" + @filename)">
@filename
/li>
}
<div id="partial">
@{
Html.RenderPartial("DevelopmentPartial",null);
}
</div>
<script>
$(document).ready(function () {
$("#filelist").click(function (e) {
@{Html.RenderAction("DevelopmentPartial", Model);
}
});
});
</script>
PartialView:
@using (Html.BeginForm())
{
var fileContents= "";
if (Model==null)
{
fileContents = "";
}
else
{
fileContents = System.IO.File.ReadAllText(Server.MapPath(Model.path));
}
@Html.TextArea("code", fileContents, new { id = "code" })
}
The result was a non-clickable list elements , 3 text editors overlap each other, and display only the contents of the last file in the list. What am I doing wrong?

[Disclaimer: I use this to attach events for Html rendered via ajax]
Two things you may want to try here.
You should not have multiple elements with the same id but you can have multiple elements with the same class.
Use .on to attach events for partially rendered html.change <li id="filelist" to <li class="filelist" change $("#filelist").click(function (e) { to $(".filelist").on("click", function (e) {

Still getting the same result. Looks like codeproject doesn't allow me to upload a picture, but the web page currently has three CodeMirror editors, all of them display the contents of the last file in the list.
The files in the list are still not clickable.
EDIT:
I modified the script :
<pre><script>
$(document).ready(function () {
$(".filelist").click(function (e) {
$('#partial').load("DevelopmentPartial")
@{
}
});
});
</script>
Now it refreshes the partial view but it doesn't display the contents of the files, even though I update Model.path onclick.

To add the event in partial rendering - notice the '.on' construct
$(".filelist").on("click", function (e) {

Stil doesn't display the contents of the file once clicked. It displays an empty editor.
I'm updating my model here:
<li class="filelist" onclick="@(Model.path = "~/Content/" + Model.Student.UserName + "/CompilerProject/src/" + @filename)">
Is that wrong?

I am rewriting an old website created, I think, using Visual Studio 2010 and am now using Visual Studio 2017. The old website had a command
Html.RenderPartial( "~/Counter/counter.ascx", new ViewDataDictionary { { "digits", 6 }, { "id", "RLSBC" } } ); which essentially displayed "id", the number of visits to the site, formatted as per "digits", 6. The variable "digits" is a .gif file of the numbers 0-9 designed in a particular way and id was displayed as a 6 digit number using digits.gif.
That statement does not work in VS 2017. It gives me an error message that essentially states that ViewDataDictionary cannot take zero parameters.
No doubt there will be other times I don't quite understand what it going on, so, is there a manual I can purchase which describes this and the other commands I will no doubt need as I progress. It would also be good if it described the use of Entity Framework, which I will need to access and SQL database.

Use Google to find the MSDN documentation.

I find the easiest thing to do is to google the class. For example, google the error or just google ViewDataDictionary and you will probably get links to MSDN help and read through those.
I can't imagine there is a manual that will walk you through what you are doing.

That's odd, because MSDN[^] says that it can. Can you post the full error message?
As an alternative, you should be able to pass an anonymous object instead of a ViewDataDictionary:
Html.RenderPartial( "~/Counter/counter.ascx", new { digits: 6, id: "RLSBC" })

The message says
'viewDataDictionary does not contain a constructor that takes 0 arguments' The problem is that MSDN isn't detailed enough. It doesn't say anywhere I could find that Html.RenderPartial should be prefixed with @ sign. That was the first thing that caused me problems. Under VS 2010, it started with <%.
And my requirements have now changed a bit. ~/Counter/counter.ascx used to count the number of visitors and overwrite the value in RLSBC.txt. I have moved that function to Start.cs to make sure it is only run once per visit. (The old method used to be run more than once per visit.) The viewDataDictionary part took id (the current number of visits) in RLSBC (RLSBC.txt) and display it as 6 characters using digits (digits.gif). Digits.gif and RLSBC.txt are both in the wwwroot/Counter directory.
Is HTML.RenderPartial / viewDataDictionary still the correct way to achieve my goals?

That doesn't match the code you posted, which was using the ViewDataDictionary class. (Note the upper-case "V" at the start, which is lower-case in your error message.)

It sounds like you've switched between view engines - you were using the older ASPX view engine, and you're now using Razor.

It sounds to me like your partial view was doing too much. The code to update the counter should not be in a view, so you've done the right thing moving it.

You're right; it does start with V and not v.
Thank you so much for the two web references. That is just what I was looking for; something that gave more detail than is provided by using Peek Definition or Go To Definition off the mouse button 2 menu.
I will read through them, learn and hopefully improve my website.
Now I need to understand how to format my counter using the .gif definition.

I create a web page with asp.net using visual.studio. And I need to acquire data from my website and save it to my computer, in a particular folder. How can I do this? Should I write this part of the program in 'Site.Master.cs' or can you tell me more exactly what I have to do, please?
NetworkAcquisitionDevice device = new NetworkAcquisitionDevice("100.0.0.1",51212,30);
FrameSearcherSecond frameSearcher = new FrameSearcherSecond();
FormatterXorByte formatterCust = new FormatterXorByte();
DataAcquisition daq = new DataAcquisition(device, frameSearcher, formatterCust);
daq.EnableDataFormatting(true);
daq.EnableFrameSearching(true);
daq.EnableDataWriting(true); // data wil be in your harddisk.
daq.StartAcquisition();
bool stop =false;
while (!stop)
{
byte[] dataFromDevice= daq.GetData();
//process data here
}
daq.StopDataAcquisition();
daq.Reset(); // it will reset all parameters.

I have a web application where I have a template (word) which I need to open/save and replace some values at run time. How do I do this?
|
|
|

If it's a new-format file (.docx), then you'll need to use something like DocX[^] or the Open XML SDK 2.5 for Office[^].
If it's an old-format file (.doc), then you'll struggle to find a non-commercial library to manipulate it.
NB: Don't be tempted to try Office Interop; aside from needing an Office license for your server, it's not supported in ASP.NET:
Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.

Below is my code. I can't figure out how to find specific text and replace it
Dim byteArray As Byte()
Dim myDataTable As DataTable = objDB.GetTemplates(plan.YearCode, "Templates", plan.State)
If Not myDataTable Is Nothing AndAlso myDataTable.Rows.Count > 0 Then
byteArray = DirectCast(myDataTable.Rows(0).Item("Template"), Byte())
Else
Throw New Exception("Unable to retrieve the specified template")
End If
Using mem As MemoryStream = New MemoryStream
mem.Write(byteArray, 0, CInt(byteArray.Length))
Using doc As WordprocessingDocument = WordprocessingDocument.Open(mem, True)
??? How do I find specific word and replace it
Helper.DownloadStream("Schedule" &" .docx", mem, Helper.WORD_CONTENT_TYPE)
End Using
End Using

I've given reference in project.json file , but when i am adding namespace in cs file , it is populating issue saying this file doesn't exist. but also when i am running this project by command prompt (dotnet run ) it is working fine , but using Visual Studio it is throwing errors for namespace.

Giving the reference does not ensure that the latest dependencies are resolved or not. To resolve the latest dependency changes, you need to run the restore command,
$ dotnet restore
Visual Studio does that all itself in the background, can you tell me which version of Visual Studio you are using? Things got changed a lot in Visual Studio 2015 and Visual Studio 2017 — Visual Studio 2017 is based on csproj, project.json and its content doesn't matter at all there.
What is .csproj file?

here's the problem
I've got an API with the following address (HTTP post)
http:
"headers": {
"accept": "application/json",
"content-type": "application/x-www-form-urlencoded"
},
"data": {
"username": "mrkeivan",
"password": "09126101185",
"uiId": "d960a994-0972-44ba-ae2c-2c3a01e135c1"
}
I need to call this api in another website and a mobile application, to do so I enabled Asp.net APi Cores globally in web config and WebApiConfig.cs
**in WebApiConfig.cs**
config.EnableCors(new EnableCorsAttribute("*", "*", "*"));
> as well as Web.config
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
<add name="Access-Control-Allow-Methods" value="POST, PUT, DELETE, GET, OPTIONS" />
<add name="Access-Control-Allow-Headers" value="content-Type, accept, origin, X-Requested-With, Authorization, name" />
<add name="Access-Control-Allow-Credentials" value="true" />
</customHeaders>
</httpProtocol>
when I call this in postman, it works perfectly
however when I call it through an ajax method or a friend of mine calls it in his mobile app project it returns the following error
> XMLHttpRequest cannot load
> http://api.novin.solutions/api/member/login. Response for preflight
> has invalid HTTP status code 404 OPTIONS
> http://api.novin.solutions/api/member/login 404 (Not Found)
I have read many articles in this matter and applied all the suggestions, but nothing fixed my problem 
any help would be appreciated
