Description
This method is used for iterating through records of the data storage to which the ProgObj driver provides access. First moves the driver to the first record of the data storage.
Declaration
ProgObj.First()
| ProgObj | An expression, variable or parameter that specifies a reference to one of the objects listed in the Applies To section | |||
| Result | None | |||
Applies To
The method is applied to the following objects:
Result Value
None.
Example
The following code demonstrates how you can change the driver and repeat a test in case of an error:
JavaScript, JScript
...
// Obtains a driver
var Driver = DDT.ExcelDriver("..//..//MyTestBook.xlsx", "TestSheet", true);
// Run some test with the driver
Result = MyTestRoutine(Driver);
// If an error occurs ...
if(! Result)
{
Driver.First(); // Go to the first record
MyTestRoutine(Driver); // and repeat the test
}
...
Python
# ...
# Obtains a driver
Driver = DDT.ExcelDriver("..//..//MyTestBook.xlsx", "TestSheet", True)
# Run some test with the driver
Result = MyTestRoutine(Driver)
# If an error occurs ...
if not Result:
Driver.First() # Go to the first record
MyTestRoutine(Driver) # and repeat the test
# ...VBScript
...
' Obtains a driver
Set Driver = DDT.ExcelDriver("../../MyTestBook.xlsx", "TestSheet", True)
' Run some test with the driver
Result = MyTestRoutine(Driver)
' If an error occurs ...
If Not Result Then
Driver.First ' Go to the first record
Call MyTestRoutine(Driver) ' and repeat the test
End If
...
DelphiScript
var
Driver, Result : OleVariant;
begin
...
// Obtains a driver
Driver := DDT.ExcelDriver('../../MyTestBook.xlsx', 'TestSheet', true);
// Run some test with the driver
Result := MyTestRoutine(Driver);
// If an error occurs ...
if not Result then
begin
Driver.First(); // Go to the first record
MyTestRoutine(Driver); // and repeat the test
end;
...
end;
C++Script, C#Script
...
// Obtains a driver
var Driver = DDT["ExcelDriver"]("..//..//MyTestBook.xlsx", "TestSheet", true);
// Run some test with the driver
Result = MyTestRoutine(Driver);
// If an error occurs ...
if(! Result)
{
Driver["First"](); // Go to the first record
MyTestRoutine(Driver); // and repeat the test
}
...
