DLL Export Reference

The VBA Padlock runtime DLL exports a set of stdcall functions that can be called directly from any language that supports Windows DLL calls. This page documents every exported function with its native signature.

VBA Padlock produces two runtime DLLs per project, one for each Office architecture. The DLL names are derived from your project name using the pattern {ProjectName}run32.dll and {ProjectName}run64.dll:

For example, if your project is named MyApp, the runtime DLLs are MyApprun32.dll and MyApprun64.dll.

Both DLLs export the same functions with the same stdcall calling convention.

Before calling any other function, the DLL must be initialized by executing a compiled function (which triggers internal setup). The VBA Bridge handles this automatically via VBAPL_Execute.

Displays the EULA dialog.

function VBAPLShowEULA(ForceDisplay: Integer): Integer; stdcall;

' 32-bit
Private Declare Function VBAPLShowEULA Lib "MyApprun32.dll" _
    (ByVal ForceDisplay As Long) As Long

' 64-bit
Private Declare PtrSafe Function VBAPLShowEULA Lib "MyApprun64.dll" _
    (ByVal ForceDisplay As Long) As Long

[DllImport("MyApprun32.dll", CallingConvention = CallingConvention.StdCall)]
static extern int VBAPLShowEULA(int ForceDisplay);

Checks if the EULA has been accepted.

function VBAPLIsEulaAccepted: Integer; stdcall;

Returns the EULA acceptance date as an ISO string.

function VBAPLGetEulaAcceptanceDate(out OutDate: WideString): Integer; stdcall;

Checks if the current license is valid.

function VBAPLIsLicenseValid: Integer; stdcall;

Returns the project-specific Hardware ID for this machine.

function VBAPLGetHardwareID(out OutHardwareID: WideString): Integer; stdcall;

Shows the activation dialog.

function VBAPLShowActivation(ForceDisplay: Integer): Integer; stdcall;

Deactivates the license programmatically (no GUI).

function VBAPLDeactivate(out OutCertificate: WideString): Integer; stdcall;

Returns the deactivation status.

function VBAPLGetDeactivationInfo: Integer; stdcall;

Shows a deactivation dialog with certificate display.

function VBAPLDeactivateGUI: Integer; stdcall;

Checks if running in trial mode.

function VBAPLIsTrialMode: Integer; stdcall;

Returns the remaining trial limit.

function VBAPLGetTrialLimitLeft: Integer; stdcall;

Checks if a license key is stored.

function VBAPLHasStoredLicense: Integer; stdcall;

Returns the registered user name.

function VBAPLGetRegisteredName(out OutName: WideString): Integer; stdcall;

Shows the trial nag screen.

function VBAPLShowTrialNag(ForceDisplay: Integer): Integer; stdcall;

Returns a project property value.

function VBAPLGetProperty(const PropName: OleVariant; const DefValue: OleVariant): OleVariant; stdcall;

Returns: The property value, or DefValue if not found.

Verifies the Authenticode signature of the runtime DLL.

function VBAPLVerifyDLLSignature: Integer; stdcall;

Performs an online license validation against the activation server.

function VBAPLValidateOnline(Silent: Integer = 1): Integer; stdcall;

Checks if an online validation is due (based on the configured interval).

function VBAPLIsValidationRequired: Integer; stdcall;

Loads localization strings from a JSON string. This overrides the built-in English strings used in activation dialogs, trial nag screens, and other UI elements.

function VBAPLLoadLocale(const JSONContent: WideString): Integer; stdcall;

Returns information about the currently loaded locale.

function VBAPLGetLocaleInfo(out OutLocale: WideString): Integer; stdcall;
