这是一个示例代码，用于估算Excel的进程是否正在运行。 （VB.NET）

Hi,
This is a sample code that estimates if a process of Excel is running. (VB.NET)

Dim proc As System.Diagnostics.Process
For Each proc In System.Diagnostics.Process.GetProcesses()
    If (proc.ProcessName = "EXCEL") then
	MessageBox.Show("Excel is running.")
    End If
Next
