使用复选框在gui中复制档案

by 白鹭 - 2022-03-17 1904 0 0

我正在 powershell 中创建一个用于复制档案的 gui。首先我添加一个带有按钮的档案,接下来我选择要复制的档案夹,然后我要复制。不幸的是,脚本说档案路径为空。我怎么解决这个问题?此外,我想添加 2 个功能。

  • 如果未标记复选框,则发出警告

  • 选择按钮旁边的文本栏位,我可以在其中看到要复制的档案的路径

    $PSDefaultParameterValues['*:Encoding'] = 'ascii'
    Add-Type -AssemblyName System.Windows.Forms

    #create form
    $form             = New-Object System.Windows.Forms.Form
    $form.Width       = 500
    $form.Height      = 300
    $form.MaximizeBox = $false
    
    #choose file button
    $Button          = New-Object System.Windows.Forms.Button
    $Button.Location = New-Object System.Drawing.Size(10,10)
    $Button.Size     = New-Object System.Drawing.Size(150,50)
    $Button.Text     = "choose file"
    $Button.Add_Click({
    Function Get-FileName($initialDirectory) {  
    [System.Reflection.Assembly]::LoadWithPartialName(“System.windows.forms”) | Out-Null
    $OpenFileDialog = New-Object System.Windows.Forms.OpenFileDialog
    $OpenFileDialog.initialDirectory = $initialDirectory
    $OpenFileDialog.filter = “All files (*.*)| *.*”
    $OpenFileDialog.ShowDialog() | Out-Null
    $OpenFileDialog.filename
    } 
    
    $file = Get-FileName -initialDirectory “c:”
    })
    $form.Controls.Add($Button)
    
    #create checkbox1
    $checkBox          = New-Object System.Windows.Forms.CheckBox
    $checkBox.Location = New-Object System.Drawing.Point (10, 100)
    $checkBox.Size     = New-Object System.Drawing.Size(350,30)
    $checkBox.Text     = "folder 1"
    $form.Controls.Add($checkBox)
    
    #create checkbox2
    $checkBox2          = New-Object System.Windows.Forms.CheckBox
    $checkBox2.Location = New-Object System.Drawing.Point (10, 150)
    $checkBox2.Size     = New-Object System.Drawing.Size(350,30)
    $checkBox2.Text     = "folder 2"
    $form.Controls.Add($checkBox2)
    
    #copy file button
    $Button2          = New-Object System.Windows.Forms.Button
    $Button2.Location = New-Object System.Drawing.Size(10,200)
    $Button2.Size     = New-Object System.Drawing.Size(150,50)
    $Button2.Text     = "copy file"
    $Button2.Add_Click({    
    
    #checkbox1 action
    if ($checkBox.Checked -eq $true)
    {
    copy-item -Path $file -Destination "C:\folder 1"
    }
    
    #checkbox2 action
    if ($checkBox2.Checked -eq $true)
    {
    copy-item -Path $file -Destination "C:\folder 2"
    }

    $form.Controls.Add($Button2)

    [void]$form.ShowDialog()

有很多改进建议,但让我们专注于您的问题:

问题是您的$file 变量的范围是函式 Get-Filename的本地因此,当从函式外部访问时,它始终为空。

如评论中所述,您的脚本作业的最小修改是更改以下行(为了清楚起见,我还建议最初在函式外部宣告它,在全域级别):

# From this
$file = Get-FileName -initialDirectory "c:"

# To this
$Global:file = Get-FileName -initialDirectory "c:"

添加具有所选文件名的文本框,请按照其他控制元件进行操作:

#Text box with choosen file name
$txtBox          = New-Object System.Windows.Forms.TextBox
$txtBox.Location = New-Object System.Drawing.Point (180, 20)
$txtBox.Size     = New-Object System.Drawing.Size(280,20)
$form.Controls.Add($txtBox)

要更新文本,请在设定 $Global:file 变量后添加以下行

$Global:file = Get-FileName -initialDirectory "c:"
$txtBox.Text = $Global:file

最后,如果您将以下代码添加到$Button2.Add_Click代码,则会显示一条讯息

#nothing checked
if(($checkBox.Checked -eq $false) -and ($checkBox.Checked -eq $false)) {
    [System.Windows.Forms.Messagebox]::Show("No CheckBox checked")
}
