how to deploy your software (set up)

[Lost User]

SQLite is not part of the standard .NET framework, it must be downloaded from the SQLite website.

Hello sir and thank you for your answer ...
I will like some advice about my program. If I want to give it to friends, I have to ask them to install system.data.sqlite on their pc? But is there not another alternative?

The alternative is that you add the requirement to your setup program, so it is automatically installed. Check the documentation for the setup generator that you are using.

Thank you I use inno setup, I will document and make you a continuation of my research

I just realized that although I managed to connect to my database thanks to you, I can not register ... here is the error message:
Failed to connect to the data source attempt to write a readonly database
attempt to write a readonly database

:wtf: :wtf:

You need to check your code and your setup. Either the database is in a protected folder, or your open statement needs an extra parameter.

I send you my code and if possible give me a link or I can send you all the program for inspection on your part

Sorry, I have no idea why you have posted all that code. You need to do some investigation and debugging to find out what is happening.

[ago2486]

ok sir i'm doing some research and giving you a follow up of my research.
Thank you for your patience and your availability

The files you need to "distribute" are in your "bin\Release" folder. Create your setup and test on your machine. Then "zip it" and send it to your fiends via the "cloud". No "CD burning". DVD/CD drives are "optional" these days ... not the ".NET framework"; unless your friends are running XP.

Thank you sir but I have an error message when I want to make a recording: Failed to connect to the data source
attempt to write a readonly database
I am looking for documentation to this problem but not in continuation

What's "in the database"? Nothing? Then create it on site. Read SQLite goes "read only" with certain installations; nothing to do with C#. Google "sqlite read only" for lots of "answers". Shoulda used SQL Server CE.

Hello Gerry Schmitz and thank you for your help, I will document and make you a return, But I would like you to guide me on a code that I saw during but research:
Read only connection
Data Source = c: \ mydb.db; Version = 3; Read Only = True;
I even use this connection but the same error message is displayed ...

[Lost User]

Sorry, don't understand the "question". I said the "install" is the problem; not the "connection string". My "solution" is SQL Server CE; otherwise, you have the internet's "solutions" ... because, I do not use SQLite.

thank you very much I am always looking for the solution of my problem. I hope to escape
