IUiLicenseManager.DeleteFeature

Fore Syntax

DeleteFeature(FeatureName: String): UiLicenseStatusCode;

Fore.NET Syntax

DeleteFeature(FeatureName: String): UiLicenseStatusCode;

Parameters

FeatureName.Feature name.

Description

The DeleteFeature method deletes license code from the current session (from memory).

Comments

The method is relevant for use only if a stand-alone license is used. Otherwise the appropriate message is displayed.

If activation code is saved to the license file, the code is to be removed manually.

Fore Example

To execute the example, place the Button and Editbox components with the Button1 and Editbox1 identifiers on the form and add a link to the the Ui system assembly. The example is a handler of the OnClick event for the Button1 component. A stand-alone license should be used.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    LicManager: IUiLicenseManager;
    Feature: String;
    StatusCode: UiLicenseStatusCode;
Begin
    LicManager := WinApplication.Instance.LicenseManager;
    Feature := Editbox1.Text;
    StatusCode := LicManager.DeleteFeature(Feature);
    If StatusCode = UiLicenseStatusCode.Success Then
        WinApplication.InformationBox("Code is successfully deleted");
    Else
        WinApplication.InformationBox("Error: " + StatusCode.ToString);
    End If;
End Sub Button1OnClick;

Clicking the button deletes code for the feature determined in Editbox from the current session. The message displays result of code deletion.

Fore.NET Example

To execute the example, add links to the Ui, Fore, ForeSystem system assemblies. Place the Button and TextBox components with the Button1 and TextBox1 identifiers on the form. The example is a handler of the OnClick event for the Button1 component. The result of the Fore.NET example execution matches with the Fore example.
