Is there any way to block a particular license and release when needed through scripting?

Rajesh Meena

I have a mixed wizard but there are limited licenses. I would like to block a particular license and release it before launching an application.

Is there any way to do that via script or subprocess using license client executables?

@AKD-Scripting-Team might have someone who knows, Rajesh.

Here is a method to check for available licenses. I have used it to wait for a license to become available. I am not aware of a direct way to hold a license. But a workaround could be to open an instance of a product that pulls the license, and close it when needed.

import System
import clr
clr.AddReference("Ans.Core.Components")
import Ansys.Core.Components
clr.AddReference("Ans.UI.Toolkit")
clr.AddReference("Ans.UI.Toolkit.Base")
import Ansys.UI.Toolkit
clr.AddReference("Ans.Utilities")
import Ansys.Utilities

def licenseCheck(args):
    ExtAPI.Log.WriteMessage('Custom License Toolbar Button Clicked')
    #this snippet shows license validation when inside the running product
    wbCapability = Ansys.Core.Components.Validation.Capability.ANSYSLI_CAP_ANS_ACT
    isLicensed = Ansys.Core.Components.Validation.Validator.Check(wbCapability)
    mssg = "invalid"
    if isLicensed:
        mssg = "valid"
    Ansys.UI.Toolkit.MessageBox.Show(System.String.Format("Validator:  Capabiliy {0} is {1}!", str(wbCapability), mssg))
    #this snippet shows license validation when outside the running product
    installDir = ExtAPI.ExtensionManager.CurrentExtension.InstallDir
    licFilePath = System.IO.Path.Combine(installDir, "licenseoutput.xml")
    if System.IO.File.Exists(licFilePath):
        System.IO.File.Delete(licFilePath)
    awpRoot = Ansys.Utilities.ApplicationConfiguration.DefaultConfiguration.AwpRootEnvironmentVariableValue
    ansysFolder = System.IO.Path.Combine(awpRoot, "..")
    sharedFolder = System.IO.Path.Combine(ansysFolder, "Shared Files")
    licFolder = System.IO.Path.Combine(sharedFolder, "Licensing")
    licPlatformFolder = System.IO.Path.Combine(licFolder, "winx64")
    licutilPath = System.IO.Path.Combine(licPlatformFolder, "ansysli_util.exe")
    ExtAPI.ProcessUtils.Start(licutilPath, "-cap", str(wbCapability), "-getcapdef", licFilePath)
    mssg = "invalid"
    if System.IO.File.Exists(licFilePath):
        doc = System.Xml.XmlDocument()
        doc.Load(licFilePath)
        node = doc.SelectSingleNode("FEATURES")
        if node.ChildNodes.Count > 0:
            mssg = "valid"
        System.IO.File.Delete(licFilePath)
    Ansys.UI.Toolkit.MessageBox.Show(System.String.Format("LIC UTIL:  Capabiliy {0} is {1}!", str(wbCapability), mssg))

Whitespace was not properly maintained when I copy/pasted (from Notepad++) @James Derrick please investigate.

EDIT: I re-copy/pasted from VSCode per @James Derrick 's advice and it is now correct.

Regarding the code formatting, this seems to be a weakness of notepad and notepad++ as I do not see the same error with code copied from PyCharm or VS Code. I am not sure why exactly it is happening, although notepad++ is known for having issues when exporting code to other applications:

It looks like notepad++ would need some configuration before it will work as you want it to.
