我已经开始了一个过程:
Dim getUdpate as Process
getUpdate = New Process
getUpdate.StartInfo.FileName = "C:\UTIL\GETBTCH.BAT"
getUpdate.StartInfo.WindowStyle = ProcessWindowStyle.Hidden
getUpdate.StartInfo.UseShellExecute = False
getUpdate.StartInfo.WorkingDirectory = "C:\UTIL\"
getUpdate.Start()
getUpdate.Close()
然后,我想运行另一个进程,但我想首先检查getUpdate进程是否已经完成.
如何检查流程是否已完成？
我已经尝试查看进程ID,但它只显示cmd.exe,并且有很多cmd.exe作为进程ID,所以我不能只是去阻止所有这些.
我有一个带有来自DataTable的项目的组合框,当表单加载时执行ff:
dbConnection = New SqlCeConnection("Data Source=Journal.sdf")
dbDataAdapter = New SqlCeDataAdapter("SELECT * FROM setting_unit", dbConnection)
dbDataAdapter.Fill(dbTable)
cbxSettingsUnit.DataSource = New BindingSource(dbTable, Nothing)
cbxSettingsUnit.DisplayMember = "name"
cbxSettingsUnit.ValueMember = "name"
当combox框中发生更改时的方法:
Private Sub cbxSettingsUnit_SelectedIndexChanged(sender As Object, e As EventArgs) Handles cbxSettingsUnit.SelectedIndexChanged
tempString = cbxSettingsBusinessUnit.Items(cbxSettingsBusinessUnit.SelectedItem).ToString
MessageBox.Show(tempString)
End Sub
该行有错误:
tempString = cbxSettingsBusinessUnit.Items(cbxSettingsBusinessUnit.SelectedItem).ToString
如何从combox框中获取所选项目？
