How to compile 64-bit libraries for qwt-6.1.2 on Windows with command line
Asked 2021-Dec-21 at 14:34We are using Visual Studio 2019, Qt5.12.3 and qwt-6.1.2 (Qwt is a graphics extension to the Qt GUI application framework) on Windows 10. Our solution has traditionally been a 32-bit only application, but we've received a request to deliver it in both 32-bit and 64-bit.
My question is specifically related to 64-bit qwt-6.1.2.
The 32-bit version of qwt-6.1.2 is compiled without problems with the following script that runs in a batch file (no, we cannot use power shell because power shell scripts are disabled on our network).

51It appears that somewhere, something is referencing some 32-bit libraries, but I can't find any documentation (I've been searching for a few days) that specifically deal with compiling a 64-bit version of qwt-6.1.2 (or any of the related qwt versions) on Windows.
Any guidance in finding the 64-bit sources, or instructions on how to compile for 64-bit would be greatly appreciated.
ANSWER
Answered 2021-Dec-20 at 22:29You are missing a call to nmake clean and so there are (even after a fresh qmake) leftovers from the 32bit-build breaking your 64bit-build.
QUESTION
WinForms Startup Event not being handled
Asked 2021-Dec-09 at 13:23I have a Windows Forms Application in .NET 5 with Application Framework activated and the startup object set to (my) MainForm.
Using "View Application Events" in the application's properties, I auto-generated the ApplicationEvents.vb file and with the given controls auto-generated a method to do something on Startup (as I understand before even the MainForm loads) - but nothing in this method gets run, not even breakpoints are triggered.
I would assume an auto-generated sub in an auto-generated file designed for this should work and every other event handling sub does, just not Startup's.
This is my ApplicationEvents.vb (without the auto-generated comment):
1Imports Microsoft.VisualBasic.ApplicationServices
2
3Namespace My
4 Partial Friend Class MyApplication
5 Private Sub MyApplication_Startup(sender As Object, e As StartupEventArgs) Handles Me.Startup
6 Debug.Print("Test")
7 MsgBox("Test")
8 End Sub
9 End Class
10End Namespace
11
Background:
I'm trying to enable high DPI scaling for my application.
For this I've tried using the app.manifest file (opened by "View Windows Settings" in the application's properties), but no combination of tags I found in the docs worked (I'm running the required version of Windows 10 of cause).
The same for the app.config file, but I expected this because it's a .NET Framework feature to use it for that.
So I landed on Application.SetHighDpiMode(HighDpiMode). This worked when put into the MainForm's Loadevent, but it only did what was intended when the form was already loaded and it was then put on a scaled up screen / the screen was scaled up while it was already loaded.
If it was started on an already scaled screen, it looked jumbled.
So I figured that enabling it only on the form loading is just a bit too late and it should be run asap, so I landed on Startup.
ANSWER
Answered 2021-Dec-09 at 13:23The startup object has to be Sub Main for the Startup event to work, not MainForm (or any form at all).
(Thanks to @Hans Passant for the tip.)
If you want to change which one is the main form later on you have to do the following:
- Close your project in Visual Studio.
- Open your project's folder in explorer.
- In it, open folder
My Project. - Open
Application.myappwith any text editor. - Change the form between the
<MainForm>tags to your (new) main forms name. - Save and close.
- Open
ApplicationDesigner.vbwith any text editor. - Find the following line and change YourMainFormsName to your (new) main forms name:
1Imports Microsoft.VisualBasic.ApplicationServices
2
3Namespace My
4 Partial Friend Class MyApplication
5 Private Sub MyApplication_Startup(sender As Object, e As StartupEventArgs) Handles Me.Startup
6 Debug.Print("Test")
7 MsgBox("Test")
8 End Sub
9 End Class
10End Namespace
11Protected Overrides Sub OnCreateMainForm()
12 Me.MainForm = Global.YourProjectsName.YourMainFormsName
13End Sub
14- Save and close.
- Open your project again and start it up. The startup form should have changed.
This way you can keep the application framework and don't have to write your own Sub Main.
QUESTION
Creating a Custom Android ROM
Asked 2021-Nov-27 at 21:06I am preparing to build a custom Android ROM and I have come across some misunderstandings that I need clarified before moving forward. My Android ROM will be rebranded and I would like to customize the OS stack but I am not sure I fully understand the concept of HAL(Hardware abstraction layer). I understand that I can create kernel modules to extend the OS but I am not sure what the HAL purpose is within the stack. How does the HAL and the kernel interact if at all?
What is the HAL? When is the HAL implemented?
Another layer of the stack I am looking at is the Android System Services layer. Would it be possible to add / modify a system service on the stack? If so, would I need to create a Binder IPC for the System Service to be called from the application framework?
I have read the documentation from the AOSP website but that is where my misunderstandings is coming from.
If anyone can help me overcome these shortcomings I would greatly appreciate it!
ANSWER
Answered 2021-Nov-27 at 21:06Ok, so I can answer your question about HAL but not so much about messing with Android services.
HAL is basically all of the files in the /dev directory on Linux systems. These files communicate with the kernel module/driver when you write to it. This basically, if the driver of the certain device you want to write to allows it, allows you to communicate with the device from a very high level point. Take a look into basic tutorials about writing kernel modules and udev. In the case of building Android though, you probably won't have to mess around with this and know it through and through unless you are making custom kernels and stuff.

QUESTION
Storing GET request parameters when initialising Open IDC auth dance for use after
Asked 2021-Oct-05 at 19:34We are implementing Keycloak as an IDP, and will use it to secure some apps (Relying Parties)
The apps are likely to use something like mod_auth_openidc, which will use the Authorization Code flow to direct the user to keycloak where the user will log in, do the openidc dance, and ultimately end up back at the "redirect_uri".
We will be calling the applications with a set of parameters, lets say for example: https://some-application/launch?person=12345
The redirect_uri is going to be https://some-application/launch, as I understand the Oauth2 spec is quite specific that the redirect_uri should be static, and not contain parameters/be dynamic.
So this means following login the request parameter "person=12345" is lost, as the user is simply redirected back to "https://some-application/launch"
What is the recommended pattern/approach to persist this "person=12345" request parameter before the OIDC dance takes place?
I have read about the "state" parameter, but I am unclear how we would inject anything into this with mod_auth_openidc, or how we would read any values from it? Is it more of an application framework question - would some kind of controller/server side code (PHP/c# etc) somehow store these values in session (but I am unclear if they would have a chance to before mod_auth_openidc kicked in?
ANSWER
Answered 2021-Oct-05 at 19:34It is an application responsibility to store the location before redirecting and to restore it afterwards:
Single Page Apps can manage this via session storage as in this code of mine since they are in control of behaviour before and after
Server Side Web Apps may give you similar options, to store the location in an HTTP only cookie, then restore it after, but you need to check for the particular tech being used. It is a well known usability issue that abrupt redirects may occur that the UI cannot control, and that deep linking (as you described) may not work.
You need an application design to solve this problem. Out of interest my recent blog post mentions this issue.
QUESTION
Symfony 4.4 Auth0 how to completely logout user from the application
Asked 2021-Aug-26 at 06:58Basic info:
I created a test application to test if SSO (Single sign on) works. I use Auth0 as a SSO provider. Symfony 4.4 as application framework. I used this article from Auth0 to create the basics. So far I can login/logout.
Problem:When I login once (with credentials), logout after and then login again I am instandly logged in with the same account I used before. Without needing to fill in credentials again. It seems to remember the session or somehow does not completely logout a user. I want the user to have to login again with credentials after it logged out. Since some of my users will use one computer for the applications (so switching user is needed).
Possible fix/Extra info:According to there docs/community I should look at this. But this seems to mean that I need API calls to add the ?federated. Which the setup example does not use (probably the library does it for me). Also my logout function in the SecurityController that is generated by the make:auth (or make:user) doesn't execute the code anymore. Even if I change the function name it still logged me out. Only untill I remove/change the route name it stops. It's probably very bad but maybe if I had the chance to execute a API call when I logout I could do this API call.
The best thing I could imagine to do is change some settings in symfony or add some small piece of code to make it logout correclty. But I dont know how.

QUESTION
How to display blog post with HTML code snippets in Laravel
Asked 2021-Aug-24 at 15:45My blog posts are saved in a DB in text format and I can't find the way of displaying HTML code between the paragraphs as you can see in the image below.
I'm using Prismjs and <pre><code></code></pre> tags..
Inside the code block there should be two <div> tags which are not displayed.
Looks like this in the database table

7<pre><code class="lang-html">
8<div>test</div>
9</code></pre>
10In my post_body.blade.php view I'm using {!! nl2br($post->body) !!} to display the content of the post.
If I use <pre><code class="lang-html">{{ $post->body }}</code></pre> on the blade view the code is visible but I have no way of including the text of the post. It would only work to show code.
I'm facing the problem of not been able to do both things, is one or the other.
ANSWER
Answered 2021-Aug-24 at 15:45There is no straightforward way of doing this by using standard Laravel/Blade output options. However it's possible to accomplish it with a little bit of extra code.
1. Why is this happening
Neither <pre> or <code> is stopping the browser to interpret the text inside as html code. They have different purpose: one is to tell the browser that the whitespaces are important and the other to tell that the content is some computer code and needs to be shown with different styling. In both cases if valid HTML code is inside the tags it will be treated as HTML.
By the way it's mentioned in Prism documentation that you need to escape the content:
Note: You have to escape all < and & characters inside < code > elements (code blocks and inline snippets) with < and & respectively, or else the browser might interpret them as an HTML tag or entity. If you have large portions of HTML code, you can use the Unescaped Markup plugin to work around this.
2. Solutions
There are different ways of solving your issue. You can either modify the input before saving it to the database and then just print the unescaped contents or modify the output and make sure you have escaped only the text in the <code> tag.
Because we don't know much about the input method you use let's focus on the second option to modify the output.
A. PrismJS
Their documentation points to a solution where you can use the Unescaped markup plugin to solve your issue. I don't have any experience with it, but the slogan says "Write markup without having to escape anything.", so it seems it will do the work.
You only need to include the plugin and then you have two options: to swap <pre><code> for <script> or to use HTML-comment to wrap your code (if you don't have other comments in the code
Just look at their examples for detailed information
B. PHP
You can use PHP to parse the text from the database and escape the content of the needed elements. In your case this is the code element. You will need to write your own implementation or use the one that I wrote for your case.
Then you can just do:

56Note: If you keep the paragraphs in the database separated only with new lines and not wrapped in <p> you will have issues using this solution and nl2br() together.

59There WAS after all an HTML tag specifically to show example HTML code as it is, but it was deprecated in HTML 3.2, BUT it seems the tag is widely supported and wrapping the code contents can be a quick and dirty solution for your case. You can see the support tables here: https://caniuse.com/?search=xmp
Read more here: https://html.com/tags/xmp/#ixzz74T0AJctF
You can accomplish this by adding the tags before saving to the database or when printing the output with JavaScript on the client side or with PHP before passing it to the blade template.

QUESTION
How should I properly go about null errors in my code?
Asked 2021-Aug-16 at 02:22I'm fairly new to Flutter Mobile application framework and I'm still trying understand Darts null safety. On line 11 I'm unsure on how to go about this error in my code.
~ Non-nullable instance field '_numberfrom' must be initialized. Try adding an initializer expression, or a generative constructor that initializes it or mark it late.
- should I mark it late and would that be proper way go about initializing 'numberfrom'?
- Line 37 I'm aswell receiving blue line on my code
Text((_numberFrom == null) ? '' : _numberFrom.toString()), ~ The operand can't be null so the condition is always false, try removing the condition, an enclosing condition, or the whole conditional statement.
Any help would be greatly appreciated thank you! I attached snippet of my code aswell, Im really looking for ideas and help to properly fix the bugs.enter image description here
