How to put value in Table (Variables)

Hi,



Since TestComplete 8.10 it's possible to add rows and columns to table variables and modify table cell values programmatically, during test execution. However, the changes you made within a table variable at runtime are not saved after the test execution is over since such variables are intended for temporary usage, not for permanent data storing. So, you can specify a table variable's structure, initialize its values from scripts and use them only during the current test run.



You can create a table variable programmatically by using the Variables.AddVariable method. After obtaining a reference to the needed TableVariable object, you can add a new column with the desired name by calling the AddColumn method of this object. To change the number of rows in the table, simply specify the needed value in the RowCount property. To get and set values of table cells, you can use one of the following approaches:



   1) Call the Item property and specify the needed column and row in its parameters to get a reference to the needed table cell.

  

   2) For each column created in a table variable, the TableVariable object contains a special property with the name coinciding with the column name. So, you can obtain a particular cell value from the needed column by calling the property with the appropriate name and passing the needed row index via property parameters.



   3) By calling the Iterator property, you can obtain an iterator that lets you iterate through the table's rows and get or set values in the needed columns.



Below is sample script code that demonstrates how you can create a table variable, initialize its cells and use the specified values during the test execution.

function TableVarTest()

{

  // Create a table variable if it doesn't exist

  if(!Project.Variables.VariableExists("MyTable"))

    Project.Variables.AddVariable("MyTable", "Table");



  // Get a reference to the variable

  var t = Project.Variables.VariableByName("MyTable");



  // Add columns to the table

  t.AddColumn("Name");

  t.AddColumn("Age");

  t.AddColumn("City");



  // Create three rows

  t.RowCount = 3;



  // Fill in the table



  // The first row

  t.Name(0) = "John Smith";

  t.Age(0) = 24;

  t.City(0) = "Seattle";



  // The second row

  t.Name(1) = "Susan McLaren";

  t.Age(1) = 35;

  t.City(1) = "Newcastle";



  // The third row (using the Item property)

  t.Item("Name", 2) = "Bob Feather";

  t.Item("Age", 2) = 59;

  t.Item("City", 2) = "Milltown";



  // Iterate through the table's rows

  var itr = t.Iterator;

  itr.Reset();

  var i = 0;

  while (!itr.isEOF()){

    Log.AppendFolder("Row " + i++);

    Log.Message("Name: " + itr.Value("Name"));

    Log.Message("Age: " + itr.Value("Age"));

    Log.Message("City: " + itr.Value("City"));

    Log.PopLogFolder();

    itr.Next();

   }

 return 0;

}

Hi,



At the moment, there is no way to add new items to a table variable and specify its structure from script - the only way to do this is to use TestComplete's GUI. We have an appropriate suggestion in our DB, and your post has increased its rating. Thank you.



BTW, you can assign a new value to the needed table variable item from script by using the Item property.

what is the syntax to use vbscript to insert a string value into a Table variable?  project.variable.<array_name>.item(i, j) = "Hi World"  doesn't work.  have tried other combinations to no avail.

now I see, was setting elements in the array then checking the table in the Variables list (where the values aren't shown).  read through the table and the values entered into the table are saved, so good enough.

I have just spent hours looking for a way to do this.
