From below code i want to send data to my controller but when i add debug point to my controller function then receiving all the values null. I dont to replace datatype is text to json.

I want to create QR Code from user data. I have using below library for creating QR Code.

I am using localDB as my database.

I have an employee table, and the employee images are stored in another table

This is my stored procedure for create and update:

Could someone please help with the following WPF - I am having an issue with being able to bind a known image name to a converter, to be able to have a checkbox show images rather than the checkbox.

Here are my static resources:

This is my code:

Description.
It is supposed to store paths to images like *.ico, *.jpg, *.png in the database.
Database types:

• SQLlite;
• SQLServer;
• MySQL;

I am using DataTable dt to simulate the result of a SELECT query.

Question.

1. How to display images in dataGridView?
2. What is the most common practice for storing images in a database? Store as paths or is it better to use other options?
3. Are there any mistakes in the code?

I am running the application.
Result: error.
Error:
Exception in DataGridView:
System.FormatException: Invalid cast "System.String" to "System.Drawing.Image".

Code

I have a problem I have previously never encountered in my life.

I have a C program which I cross compile for an ARM device. I use the LVGL library which is a graphics lib for embedded/light systems.

I have organized my project in a MVC like manner - all the views are in a folder called "screens", which has, like all other folders in the src folder of my project, its own Makefile, called by the main Makefile.

Specifically, the screens folder mostly contains files called "image_x.c", "screen_x.c" - the "image" file being a C file generated by an online converted, putting an image in an array, and the "screen" file being the source code I require to declare a screen, load an image, attach it to this screen and display that screen. This is a structure that functions, as I have used it until now, pretty much copying and pasting files and changing things in them according to my needs.

For some reason, this time, one file is simply ignored by the makefile, despite being in it AND being in the folder.

I get the following error:

I am trying to pass some functions from C++ to Python using the Qt library (Pyside2 in python). At the moment everything works correctly passing the code from one side to the other and adapting it to Python, but when I start treating images errors happen.

The only thing that I achieve is to correctly parse the shadows of the images, however, the inner part of the image (which would correspond to the rest of the colors is hollow).

I should get this

but I get this instead

And every time I treat those bytes, the program crashes with the following errors.

I am new to WPF and MVVM, and currently have the following problem, which I cannot wrap my head around.

I have a C# image database library with a database which looks roughly like this:
