Properties

• BOOL DebugInfo: Instruct MathViews to compile and execute in adebug mode. In debug mode MathViews fires events to inform the user interface(UI container) about the current file and line number. A debugger UI can suspendexecuation to inspect the stack variables.
  
  
• BOOL OkToAbort: Instruct MathViews to enable Abort() whileexecuting a lengthy computation.
  
  
• BOOL MultiThreaded: Instruct MathViews run computation in aseparate thread.
  
  

Methods

• Abort(): Abort the execution of the currently running script.
  
  
• AboutBox: Displays the About dialog box
• Evaluate(VARIANT Expression): Start execution of the specified expression
  • Expression: expression to execute. Must be a valid MathViews expression.
    
    
• GetLastError(): Return the last error (VARIANT/BSTR text)
  
  
• IsVarNameOK(VARIANT VarName): Return TRUE is validMathViews variable name (not implemented yet).
  • VarName: variable name
    
    
• SetOption(VARIANT Option, VARIANT Value): Setcertain MathViews options.
  • Option: MathViews option
    
    
  • Value: Option value.
    
    
• GetValue(VARIANT VarName, VARIANT InfoType): Getinformation about a MathViews variable.
  • VarName: MathViews varname
  • InfoType: requested information (leave blank to get all variabledata).
    
    
• GetVarList(VARIANT ProcName): Get a list of all MathViewsvariables for the specified procedure. (similar to MathViews who and/or whoscommand).
  
  
  • ProcName: MathViews procedure (leave blank for the main workspace)
    
    
• SetReturnValue(VARIANT VarName, VARIANT VarValue):Return a value to the MathViews computation engine.
  • VarName: The event name - currently ignored.
    
    
  • VarValue: The return value.
    
    
• SetValue(VARIANT VarName, VARIANT VarData): Assigna value to MathViews variable. If the variable does not exist, new variable isdefined.
  • VarName: MathViews varname
    
    
  • VarData: Variable Data (one dimensional or two dimensional array).
    
    
• Note: the computational thread waits for return value to continue computations.
  
  

Events

• AppDlg(VARIANT DialogType, VARIANT DialogTitle,VARIANT Message, VARIANT ExParam): Fired when MathViews needs tointeract with the user.
  • DialogType: Dialog type. Currently the following types aresupported: pause, input
    • 1: pause
      
      
    • 2: input
      
      
  • Dialog Title: Dialog title
    
    
  • Message: User message
    
    
  • ExParam: When a pause dialog is called, specify the number ofseconds to wait
    
    
  The user interface code should return, by calling theSetReturnValue method, numeric return value (for yes/no dialog) or a
  
  string return value (for input dialog, file/dir selection dialog, menu dialog, etc.).
• AppError(VARIANT ErrMessage): When MathViews needs toinform the user about an error.
  • ErrMessage: error message
    
    
• AppPrint(VARIANT PrintCode, VARIANT Line): WhenMathViews needs to print a line. An optional flag specifies if the currentoutput need to be ereased.
  • PrintCode: print flag
    • 0: request clear of the output window (MathViews command class)
      
      
    • 1: Append to output window
      
      
  • Line: message to print
    
    
• CalcDone(VARIANT CalcNesting): Called when thecomputational thread completed it task.
  • CalcNesting: nesting level.
    
    
• DebugInfo(VARIANT DebugFileName, VARIANT DebugLineNum,VARIANT DebugExInfo): MathViews informs the user about the progress ofm-file compilation.
  • DebugFileName: Currently compiled script (NULL if no changefrom last event)
  • DebugLineNum: Line number
  • DebugExInfo: Extra debug info
• DebugStep(VARIANT DebugFileName, VARIANT DebugLineNum,VARIANT DebugExInfo): MathViews informs the user about the progress ofm-file execution.
  • DebugFileName: Currently executing script (NULL if nochange from last event)
  • DebugLineNum: Line number
  • DebugExInfo: Extra step info
• GraphCallback(VARIANT GraphOption, VARIANT lParam):Fired when MathViews needs to draw/create a graphic window.
  • GraphOption: Graphic request type
    • 1: new graphic
      
      
  • lParam: Graphic window number. Use this number to alternate betweenseveral graphic windows.
    
    The user interface code must return, bycalling the SetReturnValue method, a valid handle to a graphic window. If thehandle is not valid, the MathViews control window will be used.
    Note:Use the MathViews Graphic Control to enable Copy to clipboard and Printfeatures.
  • ShowHelp(VARIANT Topic): Show the help topic (MathViews isexecuting 'help pHelpTopic').
    • Topic: requested topic
      
      
  • UserEvent(VARIANT EventType, VARIANT EventParam):Called by the computational thread (not implemented).
    • CalcNesting: nesting level.
      
      
  • VarChanged(VARIANT VarName): When AutoAssign is active,MathViews inform the user that the variable has been changed.
    • VarName: variable that changed
