The ClickOnce component in Visual Studio, helps you to easily create deployment packages, for your .NET apps created with Windows Forms (WinForms) or Windows Presentation Foundation (WPF).Īmong other, it supports creating deployment processes for both installed & online apps, as well as, it allows you to create self-updating app deployments. One of these tools is the ClickOnce component in Visual Studio. There are various tools and methodologies, that can help you create a deployment package/process for your.
Right after you finish the development of your application software (app), you need to provide an easy way for the end-users, in order to deploy your application on their computers.ĭeploying your app means, that you provide an efficient way for your end-users, to install, run and update your app on their computers. The Need for a Deployment Method for your. NET Programming for Beginners: Windows Forms (C#)“. The video presented in this article, is part of my online course “.
Run your application and click on the button.This article and video, helps you learn how you can use the ClickOnce Visual Studio component, for deploying your. We are ready, now lets cleanup and close our connection: String myreader = sqlite_datareader.GetString(0)
Print out the content of the text field: While (sqlite_datareader.Read()) // Read() returns true if there is still a result line to read The SQLiteDataReader allows us to run through the result lines: Sqlite_datareader = sqlite_cmd.ExecuteReader() Now the SQLiteCommand object can give us a DataReader-Object: Sqlite_cmd.CommandText = "SELECT * FROM test" But how do we read something out of our table ? Sqlite_cmd.CommandText = "INSERT INTO test (id, text) VALUES (2, 'Test Text 2') " Sqlite_cmd.CommandText = "INSERT INTO test (id, text) VALUES (1, 'Test Text 1') " Lets insert something into our new table: Sqlite_cmd.CommandText = "CREATE TABLE test (id integer primary key, text varchar(100)) " Let the SQLiteCommand object know our SQL-Query: Sqlite_cmd = sqlite_conn.CreateCommand() Sqlite_conn = new SQLiteConnection( "Data Source=database.db Version=3 New=True Compress=True ") - As C# is purely object-oriented the following lines must be put into a class: Private void Choose_Btn_click( object sender, EventArgs e) Right-click on your application and select "Open folder in your window application" and then go to:īIN -> Debug and extract your application here.Īfter this again right-click on your application and select "Add reference" and go to:īrowser -> BIN -> Debug and select DLL file (Sqlite Net.dll).ĭouble-click on the button and write the following code. Open your Visual Studio and select new project and in Visual C# select "Windows Forms Application" and provide the name as Sqlite and click on OK.
The download first link is a ZIP file so you extract this file to your application in the debug folder. There is a link, from this link you can get a DLL file link and at this link you go to the download section and download the latest version. Basically C# doesn't support Sqlite itself so we need a third-party DLL to connect to a Sqlite database. Most of mobile and small databases don't require a server and if we want to make a standalone application for one computer that doesn't depend on another server then Sqlite is perfect for us.įor more information about Sqlite you can go to this link: Sqlite. So we don't require any server for a Sqlite database. We use Sqlite because all ther other databases that we use generally require a server and Sqlite is a database that we can embed within our system.
Here I will explain how to use and connect to Sqlite in a Windows application.
