Q1: 详细阐述 vb.net 中main
每个 Visual Basic 应用程序均必须包含一个称为VB.NET Main过程。该过程为应用程序的起始点并为应用程序提供总体控制。.NET Framework 在已加载应用程序并准备将控制传递给它时，将调用 Main 过程。除非您要创建 Windows 窗体应用程序，否则就必须为自运行的应用程序编写 Main 过程。
Main 中包含首先运行的代码。在 Main 中，可以确定在程序启动时首先加载的窗体，确定系统上是否已在运行您的应用程序副本，为应用程序建立一组变量，或者打开应用程序需要的数据库。
VB.NET Main过程的要求
独立运行的文件（扩展名通常为 .exe）必须包含 Main 过程。库（例如，扩展名为 .dll）不独立运行，因而不需要 Main 过程。可以创建的不同类型的项目的要求如下：
控制台应用程序可以独立运行，而且您必须提供至少一个 Main 过程。
Windows 窗体应用程序可以独立运行。但是，Visual Basic 编译器会在此类应用程序中自动生成一个 Main 过程，因而您不需要编写此过程。
类库不需要 Main 过程。这些类库包括 Windows 控件库和 Web 控件库。作为类库部署 Web 应用程序。
声明VB.NET Main过程
有四种方法可以声明 Main 过程。它可以使用参数或不使用参数，可以返回值或不返回值。
注意
如果在类中声明 Main 过程，则必须使用 Shared 关键字。在模块中，Main 不必是 Shared。
最简单的方法是声明一个不使用参数或不返回值的 Sub 过程。
Module mainModule
Sub Main()
MsgBox("The Main procedure
is starting the application.")
' Insert call to appropriate
starting place in your code.
MsgBox("The application
is terminating.")
End Sub
End ModuleMain
还可以返回一个 Integer 值，操作系统将其作为程序的退出代码。其他程序可以通过检查 Windows ERRORLEVEL 值来测试该代码。若要返回退出代码，必须将VB.NET Main过程声明为 Function 过程而不是 Sub 过程。
Module mainModule
Function Main() As Integer
MsgBox("The Main procedure
is starting the application.")
Dim returnValue As Integer = 0
' Insert call to appropriate
starting place in your code.
' On return, assign appropriate
value to returnValue.
' 0 usually means successful
completion.
MsgBox("The application is
terminating with error level " _
CStr(returnValue) ".")
Return returnValue
End Function
End ModuleMain
还可以采用一个 String 数组作为参数。数组中的每个字符串均包含一个用于调用程序的命令行参数。您可以根据它们的值采取不同的操作。
Module mainModule
Function Main(ByVal cmdArgs()
As String) As Integer
MsgBox("The Main procedure is
starting the application.")
Dim returnValue As Integer = 0
' See if there are any arguments.
If cmdArgs.Length 0 Then
For argNum As Integer = 0 To
UBound(cmdArgs, 1)
' Insert code to examine cmdArgs
(argNum) and take
' appropriate action based on its value.
Next argNum
End If
' Insert call to appropriate starting
place in your code.
' On return, assign appropriate
value to returnValue.
' 0 usually means successful completion.
MsgBox("The application is
terminating with error level " _
CStr(returnValue) ".")
Return returnValue
End Function
End Module
可以声明VB.NET Main过程来检查命令行参数而不返回退出代码，如下所示。
Module mainModule
Sub Main(ByVal cmdArgs() As String)
MsgBox("The Main procedure is
starting the application.")
Dim returnValue As Integer = 0
' See if there are any arguments.
If cmdArgs.Length 0 Then
For argNum As Integer = 0 To
UBound(cmdArgs, 1)
' Insert code to examine cmdArgs
(argNum) and take
' appropriate action based on its value.
Next argNum
End If
' Insert call to appropriate
starting place in your code.
MsgBox("The application is
terminating."
End Sub
End Module
Q2: vb.net WinForm 工作流程如何程序化？
用一个数字做为流程标识这是可以的 但是如果用中文标识确实麻烦
给个方法参考
1:以两位数字表示流程 AB A表示序号,B表示结果 eg:11 这一阶段测试OK 20 第二阶段检测失败.或者更多也行[有点像上位机编程里的二进制数据用法,第几位到第几位是干什么用的,代表什么]
方法2 :因为流程固定,所以可以采用在数据库里给各流程步骤设计一个逻辑型的变量用于标识是否合格即可,
方法3: 也可以用不同的数据表来表示不同流程,用一个唯一id 进行关联即可
对于显示颜色 ,可以采用过程或者函数的方法节省代码
