UnlockControl

Interface AntView and AntViewGlobal

 

Type: Method

Parameters: String Company String LicenseCode

Returns: nothing

 

 

Use the UnlockControl method to unlock the license for the AntView control so that you can use it in your applications.

Provide the company name and license code exactly like it has been provided to you after you bought the control.

The unlock logic has to be done in your code, it does not save the unlock status at computer level. 

Unlocking is done at application level.

After the control is instantiated, it needs to be unlocked, before you use it to display content or navigate to a URL.

This must be done for each AntView object instance in your application.

 

You can unlock the license via the UnlockControl method for the AntView control or via the AntViewGlobal object instance for all your AntView controls in your application.

 

Example code in Visual Basic:

  

Private Sub Form_Load()

    Dim LicenseText As String

    Dim Days As Integer

    Dim eStatus As TxUnlockStatus

    

    On Error Resume Next

    Me.Show

    tbToolBar.Refresh

    Form_Resize

    

    LicenseText = "AntView License Status = "

    EdgeWebBrowser.UnlockControl "ExampleCompany", "WI5PO2-2KSU3Q-HWFXFU-IUMU2V-QF8P2F"

    eStatus = EdgeWebBrowser.UnlockStatus

    If (eStatus = usLicensed) Then

      LicenseText = LicenseText & "Licensed"

    End If

    If (eStatus = usDemoLicense) Then

      Days = EdgeWebBrowser.DemoDaysLeft

      LicenseText = LicenseText & "Demo with " & (CStr(Days)) & " Days Left."

    End If

    If (eStatus = usUnlicensed) Then

      LicenseText = LicenseText & "Expired demo license."

    End If

    InfoText.Text = LicenseText

 

    EdgeWebBrowser.CreateWebView

    EdgeWebBrowser.EventsUseHexadecimal = True ' For VB we need to use the Hexadecimal event variants

 

    If Len(StartingAddress) > 0 Then

        cboAddress.Text = StartingAddress

        cboAddress.AddItem cboAddress.Text

        'try to navigate to the starting address

        EdgeWebBrowser.Navigate StartingAddress

    End If

End Sub

 

 

Note that even if your subscription for support can expire, the license itself does not expire.

The license is valid for all versions of AntView released during your active subscription period. 

If you let your subscription expire then you can not unlock versions of AntView released after your license expired.

 

We recommend you to keep the support subscription active so that a breaking change in the WebView2 API gives you quick access to fixes in AntView. An active subscription also gives you access to any new features that are released.
