首先从UG5下面的UGOPENvs_files文件夹中拷贝VB文件夹到 Microsoft Visual Studio 9.0(我用的是vs2008)文件夹下覆盖原来文件
开启VS点击新建会找到UG5的visual basic模板,取名为Project,打开这个模板会给自动给你创建初始代码如下:
------------------------------------
Option Strict Off
Imports NXOpen
Imports NXOpen.UF
Imports NXOpen.UI
Imports NXOpen.Utilities
\'------------------------------------------------------------

\' Module MyProject

Module MyProject

\' Main()

Sub Main()
\'Add your code here
End Sub
\'------------------------------------------------------------
\'
\' GetUnloadOption()
\'
\' Used to tell NX when to unload this library
\'
\' Available options include:
\' Session.LibraryUnloadOption.Immediately
\' Session.LibraryUnloadOption.Explicitly
\' Session.LibraryUnloadOption.AtTermination
\'
\' Any programs that register callbacks must use
\' AtTermination as the unload option.
\'------------------------------------------------------------
Public Function GetUnloadOption(ByVal dummy As String) As Integer
GetUnloadOption = Session.LibraryUnloadOption.Immediately
End Function
End Module
------------------------------------
其中Sub main()是UG入口函数
此时我们从右边解决资源管理器中右键点击MyProject选择添加新项,并添加一个windows窗体组件默认名称为Form1.vb,这样我们就生成了一个窗口类,类名为Form1
然后在sub main过程中添加如下代码显示窗口:
Dim f As New Form1\'定义f为Form1类
f.ShowDialog()\'显示f窗口
此时代码完成.选择解决资源管理器,双击Project选择调试,选择启动外部调试,浏览UG主文件ugraf.exe
然后调试运行,等UG加载完成后新建或打开一个UGpart文件,按Ctrl+U调出对话框,到VS工程文件夹(默认在你的文档下)打开当前工程文件夹下的bin文件夹勾选VS生成的Project.DLL文件,这样就显示一个窗口了,当然我们可以在窗口上添加其它控件运用UGopen函数完成其它功能。
