Introduction
This article explains how to add virtual instrument controls to your MFC application from a VI Array. All virtual instrument controls  are included in the VI Array and only one DLL is needed.
.
Using VI Array
Steps for adding virtual instrument controls to your application:

• Copy files GWVIArray.h, GWVIArray.lib and GWVIArray.dll to your project directory
• And GWVIArray.h and GWVIArray.lib to your project.
• Place addGlassBoard((int)this->m_hWnd);  in OnInitDialog() for Dialog based applications, or OnCreate(LPCREATESTRUCT lpCreateStruct) for SDI/MDI based applications. It new a VI Array in your program.

Place some addIC2Container("VI Name",IDC_ID,"x,y,w,h","x,x,x,...","x,x,x,...","x,x,x,...","x,x,x,...","x,x,x,...","x,x,x,...","x,x,x,..."); after addGlassBoard. They extract virtual instrument controls from the VI Array and add them to your program.
• Using ClassWizard, add OnCommand(WPARAM wParam, LPARAM lParam) message to your application. The VI Array uses WM_Command to work.And change return CDialog::OnCommand(wParam,lParam)to return CDialog::OnCommand(wParam,0);
• In your applation's StdAfx.h header file, add this line in it
#include "GWVIArray.h"

API Functions
Following are the API functions in the VI Array. Which can be used to add a control, to set/get the value of a virtual instument control.

extern "C" long PASCAL EXPORT addGlassBoard(long hl);
Function: New a transparent VI Array to your program.
hl: HWND of the window that add the VI Array and add VI Controls.
.
extern "C" long PASCAL EXPORT delGWVI();
Function: Delete the VI Array.
.
extern "C" long PASCAL EXPORT addIC2Container(char *ICName,long id,char *p1,char *p2,char *p3,char *p4,char *p5,char *p6,char *p7,char *p8);
Function: Add a VI control to the window
ICName: Control name. For example, a Button VI's name is "Button"
id: ID or resource number of the VI. To avoid conflicting with MFC ID, it should be >6000.
*p1,*p2,*p3,*p4,*p5,*p6,*p7,*p8: Initializtion Parameters of the control.
View virtual instrument controls instruction for detail.
