This is my learning project in which I wrapped Angular 7 in .Net Core. I'm in the process of preparing the project to run in a Docker Container and connect to MongoDB that runs in a Docker Container. So I had rewrite the project so it's knows if it's running in a Docker container or just running in IIS, and for development and production environments.
Accomplishments:
Figured out how to edit the Dockerfile, and inject 2 PFX files into the .Net Core container for portable SSL.
Figured out the port mapping on 5000, 5001, 44367, and how not to load Kestrel for development, yet load it for production.
I got my Docker-Compose dialed in to create MongoDB V4.08, the static data volume, bridge network to talk to the .Net Core container.
Created a a dual appSettings.json for production and development.
Got the user secrets going, but haven't figured out the Kestrel part yet.
So far so good. But I'm getting some crazy erratic results ...
It's like it's stuck in a build and won't update.
The project always displays data from a mongo database on on another server from previous builds.
I can't get the connection string to work with the user name and password under SHA-1 using the C# Mongo Drivers, but it works without credentials, I think that's my problem.
I go to debug to confirm that it detected the Docker Container, but I can't hit the break-point, yet project.dll symbols are loaded.
It's just gotten to the point where I'm going around in circles, and need to confirm some code before I change good code.
On the data, I can Roto3T into each Mongo and see the data I created which is all different.
In startup, I read the appSettings.development.json file and add 1 more option called IsContained, which is what I was trying to hit in the break-point. If I set this extra option here, I should be able to read it in my DBContext?
What I did was try and read the Environment Variable since I wasn't able to confirm the option. But would SETTINGS contain that option?
services.Configure<Settings>(Configuration.GetSection("Settings"));
services.Configure<Settings>(
options =>
{
options.MongoDB.Connection = Configuration.GetSection("MongoDB:Connection").Value;
options.MongoDB.Database = Configuration.GetSection("MongoDB:Database").Value;
options.MongoDB.Container = Configuration.GetSection("MongoDB.Container").Value;
options.MongoDB.IsContained = Configuration["DOTNET_RUNNING_IN_CONTAINER"] != null;
}
);
private readonly IMongoDatabase _database = null;
public DbContext(IOptions<<code>Settings</code>> appSettings)
{
bool.TryParse(Environment.GetEnvironmentVariable("DOTNET_RUNNING_IN_CONTAINER"), out var isDocker);
Console.Write("DBContext IsDocker = " + isDocker);
var client = new MongoClient(isDocker ? appSettings.Value.MongoDB.Container : appSettings.Value.MongoDB.Connection);
_database = client.GetDatabase(appSettings.Value.MongoDB.Database);
}
This is for a sanity check. I had to rewrite this to accommodate containers and my portable SSL certifcates. So if I use Kubernetes in the future, more .Net app containers can be spawned with SSL self contained. Online research says I need to use Kestrel for this and bind the port with the certificate. This crashed in development when trying to use the localhost certificate but now it works using the dev-certs certificate that is registered. Haven't tried it yet in Production using a real certificate, that comes when I fix the other issues first. But I will have more Kestrel questions soon. Any help or pointers on this would be appreciated.
public static void Main(string[] args)
{
var config = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("secrets.json", optional: true, reloadOnChange: true)
.AddJsonFile($"appSettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT")}.json", optional: false, reloadOnChange: true)
.AddJsonFile($"certificate.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT")}.json", optional: false, reloadOnChange: true)
.Build();
<pre>
var appSettings = config.GetSection("Settings").Get<Settings>();
var dbSecrets = config.GetSection("Database").Get<DbSecrets>();
var env = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT");
bool.TryParse(Environment.GetEnvironmentVariable("DOTNET_RUNNING_IN_CONTAINER"), out var isDocker);
var host = CreateWebHostBuilder(args).Build();
if (env == "Production" && isDocker)
{
var certificateSettings = config.GetSection("certificateSettings");
var certificateFileName = certificateSettings.GetValue<string>("filename");
var certificatePassword = certificateSettings.GetValue<string>("password");
var certificate = new X509Certificate2(certificateFileName, certificatePassword);
var builder = new WebHostBuilder()
.UseKestrel(
options =>
{
options.AddServerHeader = false;
options.Listen(IPAddress.Loopback, 44367, listenOptions =>
{
listenOptions.UseHttps(certificate);
});
}
)
.UseConfiguration(config)
.UseContentRoot(Directory.GetCurrentDirectory())
.UseStartup<startup>()
.Build();
builder.Run();
}
host.Run();
}
Note:
Visual Studio does an OK job in getting your project into Docker for testing, but left out so many factors.
And the Internet is jammed pack with outdated information on the topic.
All the Angular stuff seem to work fine, and I think it's all .Net Core related.

Well I figured out a few things today.
My crazy issues came from the Angular wrapped in .Net Core project image that I started with.
There's a file called app.constants in Angular and a class called Configuration that is used to set the url to services in Angular to call .Net Core API's, and all the calls where going to my production server. Thus the wrong data. I just changed that file and now I can hit the breakpoints. Now I'm calling API services in the Dockerized container; I think I can fix it now that I can walk the code. It's a start in the right direction now.
If it ain't broke don't fix it

I got the SSL/TLS working today with a self contained certificate within the project running in Docker for Windows, and it connects to my MongoDB as well. It took lots of research on Kestrel and how it works. The part that sucks is that all of the examples are for developing and not production and actual deployment. Just finding the nomenclature for searching was difficult as well. But it involves certificate pinning and how to run a container with Kestrel and https.
So this segways to another question that I will post.

Can someone please help me understand why images is not displaying on this page?
I have a calendar that displays various events with appropriate pictures.
On the calendar itself, a small image is displayed (this works fine).
Here is the code for that:
<body>
<form id="Form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<dc:DataCalendar id="cal1" runat="server"
DayField="EventDate" OnVisibleMonthChanged="MonthChange"
Height="295px" Width="275px" BorderColor="#EFEFDE"
DayNameFormat="Shortest" SelectedDate="2012-11-17">
<DayStyle HorizontalAlign="Left" VerticalAlign="Top"
Font-Size="7" Font-Names="Arial" BackColor="white" />
<OtherMonthDayStyle BackColor="white" ForeColor="white" />
<ItemTemplate>
<a href='#' OnClick="javascript:window.open('admin/eventDetails.aspx?id=<%# Container.DataItem("EventID") %>','EventsDetail','width=800,height=600;toolbar=no;');" & ">
<img alt="" src='images/<%# Container.DataItem("CategoryImage") %>' height="12" width="12" align="absmiddle" border="0" /><br />
<font color='<%# Container.DataItem("CategoryColor") %>'>
<%# Container.DataItem("EventTitle") %>
</font>
</a>
</ItemTemplate>
<TitleStyle BackColor="#CEDFCE" Font-Bold="True" />
</dc:DataCalendar>
</ContentTemplate>
</asp:UpdatePanel>
</form>
</body>
en you on any given date, you are taken to the details page of that part event.
This is where a larger image is supposed to be displayed.
However, the image is not displaying. It is not even showing the little icon when picture is not present.
What am I doing wrong?
Here is that code for the eventDetails page.
Thanks in advance for your assistance.

You can't mix static and data-bound content in a server property like that. Try:
<asp:Image ID="Image1" ImageUrl='<%# Eval("CategoryImage", "/admin/memberPhotos/{0}") %>' runat="server" Height="100" Width="100" />

Hi Richard,
That didn't work. It still displays blank image but this *seems* to have worked:
age1.ImageUrl = "~/images/" & dr("CategoryImage").ToString()
Thanks for your help as always sir.
|

|

The one that didn't work is pointing to: /admin/memberPhotos/{image}
The one that did work is pointing to: ~/images/{image}
So the markup would need to look something like:
<asp:Image ID="Image1" ImageUrl='<%# Eval("CategoryImage", "~/images/{0}") %>' runat="server" Height="100" Width="100" />
"These people looked deep within my soul and assigned me a number based on the order in which I joined."

No sir, I have the image on both folders.
I was not intending to have them on both folders but I just wanted to see if any of those would work.

Hello,
I'm trying to do one page with two listboxes that filers one grid.
The only requirement is that the selection made by the user must be reflected in the URL so that it can be sent by mail to colleagues with the selection already made

First time all parameters are transmitted correctly.
The second time the whole QueryString disappears!!

Hi,
We are using Git Source Control for our project, for some reason we got a mess in our main branch when we were taking files from two branches, I want to check if there is any tool that can show us, the files that are different in two given branches if we put, just file names are enough for me, if it can show more details like what are those differences, that's also good, but if at least it shows me the files that are different it would be great.

my vs tool is : Visual Studio Community 2017 for Mac

how to fix this issue?

You have an invalid character in the source file that you are trying to compile. The message should include a line and character number telling you where the problem lies.

Hello
I am just wondering why, if I have these lines of code in my aspx file
<asp:label id="LblDate" runat="server" cssclass="dateStyle" text="Label">
<asp:panel id="pnlFormFields" runat="server">
<asp:panel id="pnlThankYouMessage" runat="server" cssclass="panel" visible="False">
why I would get the following red underlined errors (VS 2017) in my corresponding aspx.vb file:
pnlFormFields.Visible = False
pnlThankYouMessage.Visible = True
LblDate.Text = ReturnDate()
Not declared or inaccessible due to protection levels.
What should I have, please?
Thanks!

The most likely cause is that your controls are declared inside a data-bound control - FormView, GridView, ListView, etc.

Thanks, Richard, for replying.
I have this:
Function ReturnDate() As String
Code for ordinal date
End Function
And then:
Protected Sub SendEmail_Click(sender As Object, e As System.EventArgs)
SMTP code here
End Sub
And this, where the errors occur:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'user_name.Focus()
pnlFormFields.Visible = False
pnlThankYouMessage.Visible = True
LblDate.Text = ReturnDate()
End Sub
The forms tell the user 'thank you' when he clicks on 'Send' (the form), but I didn't think it would be part of the SMTP
Protected Sub SendEmail_Click , and I didn't think the 'show date'would be part of the Date Function, so I put the three lines of code above (the ones with the errors) in that
Protected Sub Page_Load
.
Thanks again.

As I said, the problem is most likely that your controls are part of a data-bound control. That's in the .aspx file, not the .aspx.vb file.
The other option would be if the CodeFile or Inherits attributes on the <%@ Page ... %> directive don't match the code-behind file.

I am trying this from many days with no success,
User first fills the registration form and after clicking submit, all JavaScript validations should fire (no field should be blank and all fields should meet criteria) and after that,all details must be saved in database (SQL)server( created table in database) and grid view must be displayed.
1. In grid view, there must be two links (select and delete) starting of every row and also one addnew button on top of the grid view.
2. when clicked on addnew button, it should display only registration form with all empty fields and submit&reset buttons(Grid view should not be visible here, only form).
3. when clicked on select link, the selected row details must appear in registration form with corresponding field values inside text boxes and after modifying those details and clicked on update button( update button must be visible below registration form only) , details must bt updated to data base.
Validation part is completed and delete also working fine.
Can any one help me with remaining query?
