Develop a NetLogic for inserting random values
This NetLogic script inserts random values into the
Table1
table of the database.Prerequisites
Set the default external code editor. See Set the default code editor.
- To develop the NetLogic
- InProject view, expand theDataStoresfolder.
- Right-click a database and select.
- Hover-over the NetLogic, select , and enterEmbeddedDatabase1NetLogic
- Double-click the NetLogic.The external code editor opens.
- In the code editor, replace the existing code with the following code:#region Using directives using System; using FTOptix.HMIProject; using FTOptix.NetLogic; using FTOptix.Store; #endregion public class EmbeddedDatabase1NetLogic : BaseNetLogic { public override void Start() { // Insert code to be executed when the user-defined logic is started } public override void Stop() { // Insert code to be executed when the user-defined logic is stopped } [ExportMethod] public void InsertRandomValues (){ // Get the current project folder. var project = Project.Current; // Save the names of the columns of the table to an array string[] columns = { "Column1", "Column2", "Column3" }; // Create and populate a matrix with values to insert into the odbc table var rawValues = new object[1000, 3]; Random randomNumber = new Random (); for (UInt16 i = 0; i < 1000; ++i) { // Column1 rawValues[i, 0] = i; // Column2 rawValues[i, 1] = randomNumber.Next(0, 5000); // Column3 rawValues[i, 2] = randomNumber.NextDouble() * 5000; } var myStore = LogicObject.Owner as Store; // Get Table1 from myStore var table1 = myStore.Tables.Get<Table>("Table1"); // Insert values into table1 table1.Insert(columns, rawValues); } }
- Save the code.
