使用 powershell 将参数从输入框传递到存储过程 - 请阅读整个内容，我知道它很长

Question

我有一个脚本，使用powershell创建一个输入框。它看起来像这样

[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing") 
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") 
$objForm = New-Object System.Windows.Forms.Form 
$objForm.Text = "Data Entry Form"
$objForm.Size = New-Object System.Drawing.Size(300,200) 
$objForm.StartPosition = "CenterScreen"
$objForm.KeyPreview = $True
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Enter") 
{$x=$objTextBox.Text;$objForm.Close()}})
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Escape") 
{$objForm.Close()}})
$OKButton = New-Object System.Windows.Forms.Button
$OKButton.Location = New-Object System.Drawing.Size(75,120)
$OKButton.Size = New-Object System.Drawing.Size(75,23)
$OKButton.Text = "OK"
$OKButton.Add_Click({$x=$objTextBox.Text;$objForm.Close()})
$objForm.Controls.Add($OKButton)
$CancelButton = New-Object System.Windows.Forms.Button
$CancelButton.Location = New-Object System.Drawing.Size(150,120)
$CancelButton.Size = New-Object System.Drawing.Size(75,23)
$CancelButton.Text = "Cancel"
$CancelButton.Add_Click({$objForm.Close()})
$objForm.Controls.Add($CancelButton)
$objLabel = New-Object System.Windows.Forms.Label
$objLabel.Location = New-Object System.Drawing.Size(10,20) 
$objLabel.Size = New-Object System.Drawing.Size(280,20) 
$objLabel.Text = "Please enter @from date:"
$objForm.Controls.Add($objLabel) 

$objTextBox = New-Object System.Windows.Forms.TextBox 
$objTextBox.Location = New-Object System.Drawing.Size(10,40) 
$objTextBox.Size = New-Object System.Drawing.Size(260,20) 
$objForm.Controls.Add($objTextBox) 
 $objForm.Topmost = $True
$objForm.Add_Shown({$objForm.Activate()})
[void] $objForm.ShowDialog()
$from

现在我想传递值$从我输入到存储过程参数@from，我尝试下面，但不工作。任何建议吗?

$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server=localhost;Database=AMSDataWarehouse      Test;Integrated Security=SSPI"
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand

 $SqlCmd.Connection = $SqlConnection
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd
$SqlCmd.CommandText = "YQBreport1"
$cmd.Parameters.Add("@from", $from)| Out-Null
$Command.ExecuteNonQuery()
$from = $Command.Parameters["@from"].value

$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$SqlConnection.Close()
$SQLResult =$DataSet.Tables[0]
$commands = $SQLResult | foreach-object -process { $_.output }> output.ps1
.output.ps1

Answer 1

一行:

$OKButton.Add_Click({$x=$objTextBox.Text;$objForm.Close()})

仅在Add_click功能中工作。为了使它可以在其他地方访问，你需要稍微修改一下:

$OKButton.Add_Click({$Global:x=$objTextBox.Text;$objForm.Close()})

$x是一个全局参数，您可以将其传递给您的过程。

Answer 2

是的，你可以使用Windows Presentation Foundation (WPF)在PowerShell中制作GUI。我试过了，失败了。

像这样读入值:

$from = Read-Host '@From'
$from

Out-GridView是我刚学到的新东西。你应该调查一下。

ls | Out-GridView -PassThru -Title 'GUI?'
