SendKeys using ScanCodes to Citrix

• Download SendKeysPlus - 7.65 KB

Introduction

You're probably here because you are trying to automate login or some other Citrix process and found that .NET SendKeys does not work with Citrix, or at least the TAB and ENTER keys don't seem to.

Background

I searched high and low as to why I could not send TAB and Enter to Citrix when I found this CodeProject article. According to posts on the net, no application has used ScanCodes for input since 1998 and I guess because of this Microsoft, never put it as an option in SendKeys. Anyways I reflected the MS SendKeys class and added the ability to send ScanCodes. This article has both Make and Break scan codes. Not sure about the difference but it works for Citrix.

Using the code

Add the SendKeysPlus code to your project and then call SendKeysPlus.SendWait like you normally would but tell what ScanCodeMode to use. ScanCodeMode of None will work like normal SendKeys.

' Just like when using the Normal SendKeys 
'the Application Must have focus When Called
SendKeysPlus.SendWait("Username{TAB}Password{ENTER}",SendKeysPlus.ScanCodeModes.Make)

Points of interest

I am not certain why Citrix uses ScanCodes other then as a way they can send extended normally non-valid keystrokes to the Citrix server.
