ICA connections using PowerShell – Part 4

Floris 14 Comments

It has been a while since I last posted something here. And in my previous post in the ICA-PowerShell series, I mentioned doing another post about simulating keyboard and mouse. To sum up, part 1 was about the ICO Object basics, part 2 was about controlling the ICA session appearance and in part 3 I talked about using the ICO Object’s events.

Enabling Simulation API

The ability to control the mouse and keyboard in an ICA session is not enabled by default. For this to work, you will need to enable the Simulation API. This is done by adding a registry key to the machine you will be using:

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\CCM]
"AllowSimulationAPI"=dword:00000001

The “CCM” subkey doesn’t exist by default, so you should create it. If you’re using a 32bit platform for testing, the registry key should look like this:

[HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Client\CCM]
"AllowSimulationAPI"=dword:00000001

ICA connections using Powershell – Part 3

In part 1 of this series, I talked about the basics. Part 2 was about the overall session appearance. This part will be about using the events which are available in the ICO SDK. The ICO SDK has a lot of events we can use, but we will be talking about a few so that you get a basic idea on how to use them.

Available Events

First of all, let’s start with the code we use to view all events in the ICAClientClass. We already had the following code:

[System.Reflection.Assembly]::LoadFile("C:\Program Files (x86)\Citrix\ICA Client\WfIcaLib.dll")
$ICA = New-Object WFICALib.ICAClientClass
$ICA.Address = "XASRV001"
$ICA.Username = "TestUser01"
$ICA.SetProp("Password","MyUsersPassword")
$ICA.Domain = "LAB"
$ICA.Application = ""
$ICA.Launch = $true
$ICA.OutputMode = [WFICALib.OutputMode]::OutputModeNormal
$ICA.DesiredHRes = 1024
$ICA.DesiredVRes = 768
$ICA.DesiredColor = [WFICALib.ICAColorDepth]::Color16bit
$ICA.Connect()

This will connect an ICA session. To view all event available, we can use the following code:

ICA connections using Powershell – Part 2

In part 1, I talked about the basics of using the ICA Client Object SDK (ICO SDK). In this second part, I’ll talk about modifying the appearance of your ICA connection using the ICO SDK. This includes:

  • Resolution
  • Color Depth
  • Fullscreen and Seamless Mode

Resolution

The resolution of the ICA connection is modified by setting two properties in your ICO SDK: DesiredHRES (horizontal resolution) and DesiredVRES (vertical resolution). By default the used resolution is 640×480. We already had the following code to make the ICA connection:

[System.Reflection.Assembly]::LoadFile("C:\Program Files (x86)\Citrix\ICA Client\WfIcaLib.dll")
$ICA = New-Object WFICALib.ICAClientClass
$ICA.Address = "XASRV001"
$ICA.Username = "TestUser01"
$ICA.SetProp("Password","MyUsersPassword")
$ICA.Domain = "LAB"
$ICA.Application = ""
$ICA.Launch = $true
$ICA.OutputMode = [WFICALib.OutputMode]::OutputModeNormal
$ICA.Connect()

Since version 10.x of the ICA Client, Citrix has shipped the ICA Client Object (ICO) SDK with the installation. This allows developers to control the ICA Client. Writing managed code using ICO is a breeze (my ICAConnect tool is using it), but you can easily write Powershell scripts which leverage the SDK.

The ICOSDK is accessible by using a DLL called “WfIcaLib.dll”, which is located in your ICA Client (or Citrix Receiver) installation directory (default is “%ProgramFiles%\Citrix\ICA Client” on 32bit platforms and “%ProgramFiles(x86)%\Citrix\ICA Client” on 64bit platforms). Now let’s have some fun with the ICO SDK using Powershell.

RDP not working after XenApp 6 uninstall

A while ago I was doing a large VSI project in a XenApp environment. While the results were not what we expected, I wanted to rule out that the bottleneck was XenApp itself. So using RDP as a connection protocol instead of ICA.

After doing some changes on the servers I tried to logon using MSTSC. It gave me a nice error message and didn’t allow me to connect.

Connecting to XenApp server through command-line

Citrix Admins out there probably know the issue; a user reports a problem and you need to troubleshoot the problem on the specific server that this user was logged on to. Logging on with user credentials to a certain server is not that easy, unless you create/modify a published desktop (or published application for that matter).

I created a little tool which allows you to easily connect to a published resource on a specific server. You can download it from the Tools section of my site and it’s called ICA Connect.
