ASCII CHR() CODE CHART for QTP, UFT and Selenium

What is ASCII and Why it's Helpful to Know

ASCII stands for American Standard Code for Information Interchange and it is a character encoding scheme based on the English alphabet.

Why does this matter?

For software development or automation of keyboard or mouse actions using automation tools like Unified functional testing or Selenium, this is very helpful.

For example, QuickTest Professional (QTP) and Unified Functional Testing (UFT) has two built-in functions (ASC and Chr) that are helpful to know when you need to work with ASCII info.

FYI this info here is not specific to QTP. Since ASCII is a standard any tool/language that you use would use the same Chr codes below. Also I originally posted this in 2010 but  the principles I cover are timeless)

In this guide, you will learn about:

Common ASCII codes (These are the most used by QTP and UFT Or Any other tool

Here are some of the most common QTP ASCII character codes I often use:

How can you actually use this?

ASC() Function

ASC()  is a QTP function that returns the code of the character passed to it. For example, if you wanted to know what the ASCII/ANSI code for the pound symbol #:

Msgbox Asc(“#”)

The above will return the code 35

Chr() Function

If you wanted to enter or search for the pound key in a string you would use the QTP Chr() function. This function will return the character associated with the code passed to it. For example:

Msgbox Chr(35)

This will return the pound sign.

That's not all…

What about mouse and keyboard actions in UFT or QTP?

There may be a time when you actually need to perform mouse or keyboard actions using screen coordinates. For a step-by-step example of how to do this with QuickTest Professional or Unified Functional Testing check out:

What about Sending Keyboard Keys using Selenium?

If you're using Selenium for your test automation and you need to pass a keypress as you do in QTP you're in luck.

Selenium has a send_keys command to send a keypress.

First, you need to import the org.openqa.selenium.Keys; library

Then when you create your script use the

.sendKeys(Keys.ENUM) syntax.

Here are some valid values you can pass:

  • ADD
  • ALT
  • DOWN
  • END
  • F1
  • F10
  • F11
  • F12
  • F2
  • F3
  • F4
  • F5
  • F6
  • F7
  • F8
  • F9
  • HELP
  • HOME
  • LEFT
  • META
  • NULL
  • TAB
  • UP

* Entering/Reading ASCII codes – when using Unified Functional Testing previously known as Quick Test Professional (QTP) – is sometimes needed to achieve certain functionality. (For Selenium check out Send_Keys)
