Hotkeys in Citrix XenApp session

There is already a lot of information about how to control your hotkeys in a XenApp session.
At a customer, this still led to some confusion about when and where the config should be done.

This was kind of tricky because they saw that external users experienced different behavior than internal users.

So the first stop was, which interface is used by which user. Internally the users were directed to the internal Citrix Web Interface (yes, old school).
So on the old Web Interface the Default.ica in C:\inetpub\wwwroot\$$websitename$$\conf\ is used to edit the available hotkeys. For a full explanation about this, check

The external users are directed to a Netscaler also using the Web interface but this time the one that is available in the Netscaler. So editing the hotkeys must be done in the Netscaler. Read more

Thinapp: Child process keeps SandBox locked

One of the best practices when packaging with ThinApp includes verifying no processes are left running that lock the Sandbox when you shuts down the application. You can simply verify this by trying to delete the package’s Sandbox. If it is locked and you cannot delete it, some process is still running.
To determine wich process locks the sandbox i use Process Explorer.

In my case the child process ‘svchost.exe’ kept the sandbox locked.
Because it was running outside of the thinapp the ‘OnLastProcessExit function’ is never called.

Error 242 when deploying image with HP Device Manager 4.4

When i tried to update/deploy an image from HP Device Manager 4.4 to a Compaq 6720T it constantly failed with the following error:

Fail to execute PushImage task
ErrorCode: 242, Error Detail: Failed to seek image file to end
Fail to execute common task
ErrorCode: 242, Error Detail: Failed to seek image file to end

After some troubleshooting i came to the conclusion that the HPDM agent is not up to date on the client. Make sure that your Agent and your HPDM are the same version, otherwise you can not image from HPDM. 
In HPDM there is the Agent tab, drag and drop the Update Agent template on the unit.  Once that is complete you should be able to image your system.

Use Windows 7 as Virtual Router

Sometimes it’s just handy to use you’re laptop as a Wifi Hotspot. There are a lot of applications to do that, but the ones that actually work cost a bit. So why not use the built in utility of Windows 7? This is how you can do that.

  1. Open a command prompt with administrative privilges
  2. Enter the following command: netsh wlan set hostednetwork mode=allow ssid=WIN7 key=password This will create a wireless access-point with SSID of “WIN7”
  3. Open Networks and Sharing Center and enable the newly created wireless connection.
  4. Share the interface with an internet connection to the newly created wireless connection.


Now you can start the interface with the following command: netsh wlan start hostednetwork

VMware ThinApp package crashes with VBS.

For the intergration of VMware ThinApp applications into RES Workspace Manager, a custom VBS is required in the root of the Setup Capture files folder.
The following code must be present in the script:

Function OnFirstParentStart
WaitForProcess ExecuteVirtualProcess(GetEnvironmentVariable(“pwrgrids”)),0
End Function

But some ThinApp applications failed to start after that, or any vbs script was added to the build.
