This protected member contains persistent AutoResizeViewer state which should be initialized in Init()()().

This protected member contains persistent BackColor state which will be updated from Visual Signal viewer properties before DoCompute()()() is executed.

This protected member will be initialized and updated by Visual Signal's ExternalDll module via setInputDescriptors(String), setInputCoordinates(Int32, Int32, array<Object>[]()[]), setInputDataRe(Int32, Int32, array<Double>[]()[]), and setInputDataIm(Int32, Int32, array<Double>[]()[]). The user DLL can directly access the DllData objects to obtain the data descriptor information.

This protected member contains persistent Title state which will be updated from Visual Signal viewer properties before DoCompute()()() is executed.

This protected member contains the System.Windows.Forms.Panel-derived object which should be initialized in Init()()(). This member can be accessed via the ViewerPanel proeprty.

Protected function "AcceptInput", proved to the user DLL for registering input types acceptable by the DLL for computation. This function should be invoked in Init()()(), and the registered acceptable input types will be passed to Visual Signal's ExternalDll module via getDllInfo()()(). Visual Signal will use this information to determine whether an input connection is valid or not.

Protected function "AcceptInput", proved to the user DLL for registering input types acceptable by the DLL for computation. This function should be invoked in Init()()(), and the registered acceptable input types will be passed to Visual Signal's ExternalDll module via getDllInfo()()(). Visual Signal will use this information to determine whether an input connection is valid or not.

If this property is set to "True", instruct the Visual Signal viewer to resize itself base on the control's size If set to "False", Visual Signal will try to resize the control based on the viewer's size. This property should be set in Init()()().

Get the viewer background color The value will be updated from Visual Signal viewer properties before DoCompute()()() is executed.

Interface for exported function "compute", used by Visual Signal's ExternalDll module to execute the actual computation provided by the user DLL. This function just calls the protected function DoCompute()()(), which the user DLL must override with own implementation.

Protected virtual function "DoCompute", intended to be overridden by the inherited user DLL class to provide the actual computation. This function is called by the exported function compute()()() which is in turn used by Visual Signal's ExternalDll module to start computation.

Determines whether the specified Object is equal to the current Object.

Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.

Exported function "getDllInfo()", used by Visual Signal's ExternalDll module to obtain DLL info such as name, version, API version, langauge, license control and properties.

Serves as a hash function for a particular type. GetHashCode()()() is suitable for use in hashing algorithms and data structures like a hash table.

Protected function "GetInputCoord", provided to the user DLL to obtain the input coordinates.

Protected function "GetInputDataRe", provided to the user DLL to obtain the imaginary part of the input data.

Protected function "GetInputDataRe", provided to the user DLL to obtain the real part of the input data.

Exported function "getOutputCoordinates", used by Visual Signal's ExternalDll module to obtain the output data coordinates from the user DLL.

Interface for exported function "getOutputDataIm", used by Visual Signal's ExternalDll module to obtain the output data (imaginary part) from the user DLL.

Exported function "getOutputDataRe", used by Visual Signal's ExternalDll module to obtain the output data (real part) from the user DLL.

Exported function "getOutputDescriptor", used by Visual Signal's ExternalDll module to obtain output descriptor from the user DLL.

Exported function "getProperties", used by Visual Signal's ExternalDll module to obtain property values from the user DLL.

Gets the Type of the current instance.

Exported function "getViewerPanel()", used by Visual Signal's ExternalViewer module to obtain external viewer object created by the user Dll

Set this property in Init()()() to register the infoText of the user module. This will appear in Visual Signal as a tooltip for the dll.

Protected virtual function "Init", intended to be overridden by the inherited user Dll class to provide the initialization function. This function is called by the exported function getDllInfo()()().

Set this property in Init()()() to register the license manager ID. If a license manager matching the ID were found, Visual Signal will attempt to use license control for the user module. If the property is not set or set to an empty string, license control will not be used for the user module.

Set this property in Init()()() to register the license name. Visual Signal will attempt to match the license name against any license files loaded by the license manager. If no valid license file matches the license name, then the user module will not be available for use in Visual Signal. For security reasons, the module will also not be available if a license manager matching LicenseManagerID were *not* found.

Creates a shallow copy of the current Object.

Set this property in Init()()() to register the minimum number of inputs acceptable by the user DmoduleLL.

Set this property in Init()()() to register the name of the user module.

Protected function "RegisterProperty", proved to the user DLL for registering properties used by the DLL computation. This function should be invoked in Init()()(), and the registered properties will be passed to Visual Signal's ExternalDll module via getDllInfo()()() and become available in the module's property dialog for editing. The current values will be communicated back and forth between ExternalDll module and the user DLL via setProperties(String) and getProperties()()() exported functions.

This function should be invoked in Init()()(), and the registered properties will be passed to Visual Signal's ExternalDll module via getDllInfo()()() and become available in the module's property dialog for editing. The current values will be communicated back and forth between ExternalDll module and the user DLL via setProperties(String) and getProperties()()() exported functions.

Exported function "setBackColor()", used by Visual Signal's ExternalViewer module to set external viewer background color

Override protected function SetExtendedInfo(XmlDocument) to set additional viewer-specific root atributes. This function is called by the exported function getDllInfo()()().

Exported function "setInputDataIm", used by Visual Signal's ExternalDll module to set the input data (imaginary part) in the user DLL.

Exported function "setInputDataRe", used by Visual Signal's ExternalDll module to set the input data (real part) in the user DLL.

Exported function "setInputDescriptors", used by Visual Signal's ExternalDll module to set input descriptors in the user DLL.

Exported function "setProperties", used by Visual Signal's ExternalDll module to set property values in the user DLL.

Exported function "setTitle()", used by Visual Signal's ExternalViewer module to set external viewer title

Get whether to show the title in the viewer. The value will be updated from Visual Signal viewer properties before DoCompute()()() is executed.

Get the viewer title string The value will be updated from Visual Signal viewer properties before DoCompute()()() is executed.

Returns a String that represents the current Object.

Protected function "UpdateProperty", provided to the user DLL for updating the current property values. This function is usually invoked in the DoCompute()()() function after the computation stage.

Virtual hook function "UpdateViewerProperty()". This function can be overridden in user's code to provide custom behaviour for updating viewer properties.

Set this property in Init()()() to register the version of the user module.

Set the external vewer System.Windows.Forms.Panel object. This property should be set in Init()()().
