Note  This function signature is shown as it appears when you create a client using the LabWindows/CVI ActiveX Controller Wizard. If you create a client for the LabWindows/CVI ActiveX server interface using a different development environment, this function might be exposed differently. Some of the parameters documented here, such as objectHandle or errorInfo, are not applicable if you write a client using a different development environment.

Purpose

Creates a new function panel.

Note  You can discard the function panel and its parameters after inserting the function panel into a function tree.

All of the methods that you can apply to a particular object are grouped under a single class in the function tree. The name of the class corresponds to the type of the object to which this handle refers.
fpNodeName const char * The name of the function panel window to create.
functionName const char * The name of the function for which to create the new function panel.

errorInfo ERRORINFO * When an ActiveX server function fails with the error code DISP_E_EXCEPTION, descriptive information about the error code is stored in this parameter. The information can include the error code, source, and description. It also can include a help file and help file context ID.

When an ActiveX server function fails with the error codes DISP_E_PARAMNOTFOUND, DISP_E_TYPEMISMATCH, or E_INVALIDARG, the parameter position of the invalid argument may be stored in the errorParamPos member of this parameter.

You can pass NULL for this parameter.
functionId long * The ID used to identify the function panel in subsequent function calls.
returnValue long * The value that the LabWindows/CVI ActiveX server function returns. A negative value indicates that the LabWindows/CVI ActiveX server function returned an error.
