If a LabVIEW application distributed with BLT is ran in an environment where a Proxy filters the Internet connections, the application will not be able to download the product updates.

If your application run behind a proxy, you must configure the proxy settings in order to allow it to download product updates.


Follow the steps below to configure the proxy settings for your BLT Application:


Method 1


•On the computer where your application runs, Edit the file at: %ProgramData%\STUDIO BODs\<Name of your application>\proxy_config.ini (create the file if it doesn't exist).

The content of the file should look like:


[PROXY]

Server = "10.10.10.1"

Port = 3128    

Username = "jondoe"

Password = "123456"


Replace with the correct IP Address, Port and Credentials. 

The Username and Password are only needed if your proxy server requires authentication. 

Your proxy server must support Basic Authentication.


Restart the application and it will now use the proxy settings when downloading product updates.


Method 2


If you want to remotely set the proxy settings for your deployments, you might do this by using the BLT Product Features.


•Create a new Feature for your Product. In this example, we name it "Proxy config"
Set the following attributes for this Feature:

oServer

oPort

oUsername

oPassword




•Keep note of the Feature ID since we will need it later. In our example, this Feature ID 24


•Set the Product Feature Attributes values for your Licenses. To do this, select the License in the BLT Dashboard and click on the "Configure Product Permissions" button.
Drag and Drop your "Proxy Config" feature from the Left to the Right to give permissions to the Licensee.
Click on the "Set Attributes Values" button and enter the proper values for the user(s) of this License.
Click OK and Apply to save the changes and repeat this operation for any License that requires a proxy configuration.




•Then you need to implement some changes in your application to retrieve the Licensee Proxy config from the BLT Server.
Create a new VI in your LabVIEW Project for your application and implement it as shown below: (in our example, we name this VI "Get Proxy Config.vi")



•Implement the following change in the BLT_Main VI of your application (Search for "BLT_Main" in your LabVIEW Project to locate the VI).
(The change occurs in the  "Product Updates: Check" case of the main Case Structure)



•Save your changes, Rebuild and Distribute your application.


Note that Method 2 will override any Proxy Config that might already be set using Method 1.
