You already have the names of 3rd party libraries. If you go and study them you should be able to decide which one suits your needs.
|
|
|
|
|
yes ok but i need a piece of code to extract tables from pdf and show on datatable in c#.
|
|
|
|
|
Yes, but you need to write the code first.

Problem
What layers required for make asp.net core 2 project for prevent repeat data ?
I need to make new project with asp.net core 2.1 using Generics and i have more questions
How many layers used ?
which layer must have initialize of connections ?

Anything related to data and database connection should be placed inside your Data Access layer. Anything related to Business rules and validation should be placed inside your Business Layer or whatever you want to call it.
|
|
|
|
|
In most of our web services I use the repository pattern. Isolating data access from business rules from controller/services.
Here is a link to some docs on Microsoft. This isn't specific to Dotnet Core, but the same pattern can still be applied.

Hi,
I have the following Web Api methods, I want to call and test my methods from a mocking application, if possible any code, following are my Web api methods:
[Produces("application/json")]
[Route("api/Employee")]
public class EmployeeController : Controller
{
EmployeeDataAccessLayer objemployee = new EmployeeDataAccessLayer();
[HttpGet("[action]")]
public IEnumerable<TblEmployee> Index()
{
return objemployee.GetAllEmployees();
}
[HttpPost]
public int Create(TblEmployee employee)
{
return objemployee.AddEmployee(employee);
}
[HttpGet("{id}")]
public TblEmployee Details(int id)
{
return objemployee.GetEmployeeData(id);
}
[HttpPut("{id}")]
public int Edit(int id, TblEmployee employee)
{
return objemployee.UpdateEmployee(employee);
}
[HttpDelete("{id}")]
public int Delete(int id)
{
return objemployee.DeleteEmployee(id);
}
[HttpGet("[action]")]
public IEnumerable<TblCities> GetCityList()
{
return objemployee.GetCities();
}
}

Mocking in tests is to replace the access of external resources with other things like hard-coded values so that you can test the business logic in your app independent of other things. So the short answer is that you would probably mock the entire web EmployeeController so that any code that calls the webapi would call your mocked controller instead.
If it is the controller itself you want to test then you would mock out the data access, in this case your EmployeeDataAccessLayer, so you could call the methods on your controller from a unit test without needing database access. However your controller methods don't really do anything, there is no logic in them, they just act as an interface to calls on the data access layer. So long story short, there is nothing here worth testing.

xUnit unit testing framework has the ability to use external data sources for unit testing.
For example you could create a spreadsheet or a database table will a randomized set of data that can be used as the mocked source data for your unit testing.
Here is a link to a blog post discussing it.

When we are using Microsoft Test runner we use Moq to build out our mock data layer. We recently have been switching to xUnit, I haven't tried using Moq with it yet.
Here is the link to the Moq GitHub repo, there's good info here.

Hi,
I am trying to learn React.Js, I am trying to start with a small Hello World application, the problem is, I am not able to integrate React.Js with with MVC that I have or even MVVM, what I want is, I write some jsx file I want to execute it part of my MVC application. Just like I used to write code for my previous applications and just execute them when I press F5, am I doing anything wrong here? Can't I write jsx files as part of my MVC application and call them and execute them just by pressing F5?
Any guide for me for integrating my MVC or Web Api application with React.Js or Angular 2.0 anything is fine, I am getting very frustrated because there very less help for executing React or Angular as part of Visual Studio, I am searching a lot, but I couldn't execute even a single link successfully.
Need some help, if anything that can explain me those basic things to execute at least one application successfully - please.
I put some money in Udemy for react that guy is teaching more of Passport than react and ASP.Net MVC full stack - very sad.
Any help a link or a suggestion anything helps me, because even the errors are not descriptive they are not explaining me why something is failing - frustrated, please any help.

Have you created your project type as a Web Application type? Other types won't fire up the internal IIS Express server. This is moot if you're rolling with a stand-alone web server, but that doesn't sound like the case.
If you're using MVC, is your base jsx being served by your home controller? If not, that would be a problem, but I frankly wouldn't use MVC.NET for this, I would use WebAPI with a static files section.

I applaud your ambition on learning React or Angular, a path I took last year and started out integrating my learning with a MVC project which was quite a steep learning curve. Yes you can integrate ReactJs and Angular into a MVC project, and even a .Net Core project, but you have to change the way you think about programming and .Net.
Keep in mind that ReactJs and Angular doesn't require a .Net environment. .Net is just used as a back end to feed data to the client script pages. In hindsight, I found using .Net for the back end much harder to deal with than using say pure Java or Typescript for the whole thing.
I would like to seed your ambition with some files and code, but It's just too large to post here.
I actually build a large project that uses ReactJs both client and server side and works great.
But rendering ReactJs on the server side requires a library of JavaScriptEngines which gets complicated.
Start with the client side first, then work your way to the server side.
But this is where I started.

I have 2 .net forms, each with their own BindingSource which I set to go after the same DataTable. The table is filled early on with 35 rows. One of the BindingSources has a filter set when the form loads, which makes the result set 4 rows. When I go back to the first form, the row count has gone down to 4 - if I set that BindingSource filter to "", the count returns to 35.
It looks as if the two binding sources are sharing stuff, where changing the filter on one affects the other.
Any explanation for this? I am working around it but would like to understand the mechanism.

Maybe I'm confused, but this post is in ASP.NET Web Development. Right?
In ASP.NET Web development, there is no BindingSource. (or am I crazy ?)
There is SQLdatasource (and other datasources).
Is this Post supposed to be in the Windows Development area?
If you need help with SQLdatasource, I can offer some assistance; just need a code example.

Thanks, you are correct, BindingSource is probably specific to win forms and not one of the many shared classes with asp.net. I will repost in the win dev area, this problem is specific to the BindingSource implementation.

What do you mean by "cursor"? If you mean the mouse pointer then you can't control that, if you mean the caret then html doesn't support that, only text boxes do.

Good Afternoon,
I am working on a project where I will need a custom control added to a site. Since I have never worked with them previously, I decided to try and make a very basic control and a test site so I can learn how to do everything properly. For instructions, I was using the steps outlined on Microsoft's website here. Therefore I created a solution with two projects - Custom Control Assembly and Custom Control Test Site, both of which are using the 4.7 version of the .NET Framework.
For the Custom Control Assembly, the Assembly name is CustomControlAssembly and the Default namespace is CustomControlNamepsace. There is one file in the project called CustomControl which inherits from
System.Web.UI.Control . This project built without any errors and I copied the CustomControlAssembly.dll to the /Custom Control Test/Custom Control Test Site/bin folder as instructed on the Microsoft page listed above.
The Custom Control Test Site is a web forms site. On the Default.aspx page I added the following directive right underneath the
<%@ Page %> directive:
<%@ Register TagPrefix="Custom" Namespace="CustomControlNamespace" Assembly="CustomControlAssembly" %>
In the page, I am able to add the following tag and IntelliSense correctly finds it:
<Custom:CustomControl runat="server"></Custom:CustomControl>
However, if I try to add an ID properties (in order to name it like I do with all ASP.NET controls), like the following:
<Custom:CustomControl runat="server" ID="CustomControl1"></Custom:CustomControl>
I get the following error message:
CS0400 - The type or namespace name 'CustomControlNamespace' could not be found in the global namespace (are you missing an assembly reference?)
If I take the ID="CustomControl1" out of the tag, then the site will build fine again. However, when I run the site, the custom control does not show anything on the site. I tried updating the CustomControl to inherit from
System.Web.UI.UserControl instead of
System.Web.UI.Control but it still doesn't display on the Default.aspx page. The following is the markup of the CustomControl.ascx file:
<pre><%@ Control Language="C#" AutoEventWireup="true" CodeBehind="CustomControl.ascx.cs" Inherits="CustomControlNamespace.CustomControl" %>
<table>
<tr>
<td>First Name:</td>
<td><asp:TextBox runat="server" ID="txtFirstName"></asp:TextBox></td>
</tr>
<tr>
<td>Last Name:</td>
<td><asp:TextBox runat="server" ID="txtLastName"></asp:TextBox></td>
</tr>
<tr>
<td colspan="2" style="text-align: center"><asp:Button runat="server" ID="btnShowName" Text="Show Name" OnClick="btnShowName_Click"/></td>
</tr>
</table>
<br/>
<br/>
<asp:Label runat="server" ID="lblFullName"></asp:Label>
And the code-behind is:
using System;
namespace CustomControlNamespace
{
public partial class CustomControl : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnShowName_Click(object sender, EventArgs e)
{
string firstName = txtFirstName.Text.Trim();
string lastName = txtLastName.Text.Trim();
string fullName = $"Hello {firstName} {lastName}! If you are seeing this message, then the custom control " +
$"is working successfully.";
lblFullName.Text = fullName;
}
}
}
So I have two errors - First, why can't I added an ID to the custom control and second, and more importantly, why is the custom control not showing on the Default.aspx page even though the control and site built fine, without any errors or warning. Even when I inspect the HTML of the Default.aspx page, where the control should be, it is just empty.
Any help, guidance, or suggestions would be greatly appreciated. I have been at this for over an hour and a half and can't find anything that would explain why these issues are occurring. Thanks in advance for any help you can provide.
