ValueByIndex Property

Applies to TestComplete 15.0, last modified on October 22, 2021

Description

The ValueByIndex property lets you obtain the value stored in the cell, which is specified by its column’s index.

Since the test log layout is customized, the ValueByIndex property does not provide a reliable way to obtain the desired value. See Remarks for details.

Declaration

LogTableRowObj.ValueByIndex(Index)

Read-Only Property Variant
LogTableRowObj An expression, variable or parameter that specifies a reference to a LogTableRow object
Index [in]    Required    Integer    

Applies To

The property is applied to the following object:

Parameters

The property has the following parameter:

Index

The index of the column to which the desired cell belongs. The index is zero-based, that is the first column has index 0, the second - 1, and so on. The index of the last column is LogTableDataScheme.ColumnCount - 1.

Property Value

The value of the specified cell. It can be an integer or a floating-point number, a string, a boolean, a date-time value, a hyperlink or an image.

Note: To determine the type of values in the given table column, you can use the LogColumn.DataType property.

Remarks

If you use Python or DelphiScript, you should enclose the parameter of the ValueByIndex property in square brackets: ValueByIndex[Index].

It is not recommended to use the ValueByIndex property to obtain the value in the desired cell. This is because the index of the table column is dependent on the table layout, which is customized. So, the scripts which use the ValueByIndex property may not work correctly on another computer, or even on your computer if you change the log layout, for example, add or remove table columns or change their order.

It is more reliable to use the Value or ValueByName property instead of ValueByIndex.

Example

The following example demonstrates how to obtain the value stored in the specified cell.

JavaScript, JScript

function TableDataRowSample()
{
  var Logs, LogItem, LogData, DType, Row, Column, Value;
  // Obtains a log item
  Logs = Project.Logs;
  LogItem = Logs.LogItem(0);
  // Obtains the log item’s dataset
  LogData = LogItem.Data(0);

  DType = LogData.Scheme.DataType;
  // Checks whether the dataset corresponds to the table
  if (DType == 0)
  {
    // Obtains a table row by its index
    Row = LogData.Rows(0);
    // Obtains the value stored in the cell by the column index
    Value = Row.ValueByIndex(1);
    // Posts the value to the test log
    Log.Message(aqConvert.VarToStr(Value));
  }

}

Python

def TableDataRowSample():
  # Obtains a log item
  Logs = Project.Logs
  LogItem = Logs.LogItem[0]
  # Obtains the log item's dataset
  LogData = LogItem.Data[0]
  DType = LogData.Scheme.DataType;
  # Checks whether the dataset corresponds to the table
  if DType == 0:
    # Obtains a table row by its index
    Row = LogData.Rows[0]
    # Obtains the value stored in the cell by the column index
    Value = Row.ValueByIndex[1]
    # Posts the value to the test log
    Log.Message(aqConvert.VarToStr(Value))

VBScript

Sub TableDataRowSample

  ' Obtains a log item
  Set Logs = Project.Logs
  Set LogItem = Logs.LogItem(0)
  ' Obtains the log item’s dataset
  Set LogData = LogItem.Data(0)

  DType = LogData.Scheme.DataType
  ' Checks whether the dataset corresponds to the table
  If DType = 0 Then
    ' Obtains a table row by its index
    Set Row = LogData.Rows(0)
    ' Obtains the value stored in the cell by the column index
    Value = Row.ValueByIndex(1)
    ' Posts the value to the test log
    Log.Message(aqConvert.VarToStr(Value))
  End If

End Sub

DelphiScript

procedure TableDataRowSample();
var Logs, LogItem, LogData, DType, Row, Column, Value;
begin
  // Obtains a log item
  Logs := Project.Logs;
  LogItem := Logs.LogItem[0];
  // Obtains the log item’s dataset
  LogData := LogItem.Data[0];

  DType := LogData.Scheme.DataType;
  // Checks whether the dataset corresponds to the table
  if DType = 0 then
  begin
    // Obtains a table row by its index
    Row := LogData.Rows[0];
    // Obtains the value stored in the cell by the column index
    Value := Row.ValueByIndex[1];
    // Posts the value to the test log
    Log.Message(aqConvert.VarToStr(Value));
  end;

end;

C++Script, C#Script

function TableDataRowSample()
{
  var Logs, LogItem, LogData, DType, Row, Column, Value;
  // Obtains a log item
  Logs = Project["Logs"];
  LogItem = Logs.LogItem(0);
  // Obtains the log item’s dataset
  LogData = LogItem["Data"](0);

  DType = LogData["Scheme"]["DataType"];
  // Checks whether the dataset corresponds to the table
  if (DType == 0)
  {
    // Obtains a table row by its index
    Row = LogData["Rows"](0);
    // Obtains the value stored in the cell by the column index
    Value = Row["ValueByIndex"](1);
    // Posts the value to the test log
    Log["Message"](aqConvert["VarToStr"](Value));
  }
