Visual Basic

I need some guidance and advice to build a questionnaire system similar to Google forms that include two parts,

the first part is a desktop system with vb.net or c# and separate SQL server database (it must be a desktop system because it will be part of a vb.net old system, The new project will be called from within the main interface of the old project )

and the second part is a web system, and the two systems are linked to one SQL server database through a local network and a local server

the desktop system builds multiple questionnaires forms and each questionnaire is associated with a specific user to answer these questions through the web system via the username that will be assigned to him by the desktop system... Here, I would like to note that each user has a different questionnaire from the other...

The desktop system will also use the answers to build a dashboard has charts and report based on the analysis of the answers

My questions ...

1- What is the best way to design (questionnaire builder) if I want it to work and similar to Google Forms method and user interface of building questions if each user has its own questionnaire that contains an unlimited set of questions, the new question is added through the Add button and each question is specified by the admin It determines the nature of the answer and the answer and contains a tool to choose a specific classification from a group of classifications that are added to the system, and each question contains in addition to the answers a field of notes and evaluation from 1 to 5, and after building this questionnaire for a specific user it is permanently saved and linked with this user and there is a possibility to edit these questions on This questionnaire for the future.

Is the User Control method the best way to build a question-building interface, or is there a better way and how?

2- What are your tips and directions that help me to build a better design for such a system?

Greetings

Hi, I need help looking for the code to send an image via the bot

Helo, acording to this code (In Visual Basic for word):
The code works for me, but it is not what I want...

The problem is: I only wont to select a colored text (example -> A text colored in Red), selecting all the words colored by Red. 
I am very frustrated because I have tried everything but it does not work for me.
My goal is taking that colored text to another word document. The most important colored text i have in the document is colored in blue sky.
Sorry for the writing and thank you for your trouble.


//Replace text color//

        With Selection.Find
            .Text = ""
            .Replacement.Text = ""
            .Forward = True
