Vba 如何执行Prnt屏幕并将其保存到特定文件夹中,vba,internet-explorer,automation,Vba,Internet Explorer,Automation,我找到了一个代码，可以在不使用Sendkeys方法的情况下执行Prnt屏幕： Option Explicit Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal _ bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long) Private Const VK_SNAPSHOT = &H2C Sub PrintScreen

我找到了一个代码，可以在不使用Sendkeys方法的情况下执行Prnt屏幕：

Option Explicit

Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal _
  bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)

Private Const VK_SNAPSHOT = &H2C

Sub PrintScreen()
    keybd_event VK_SNAPSHOT, 1, 0, 0
End Sub
我还没有尝试过它是否能正常工作（如果不能，我将使用Sendkeys），但我想知道是否有办法将其保存为.pdf/.jpg（无所谓）到一个特定的文件夹中。所有的打印屏幕都是关于Internet Explorer页面的。

您的代码只模拟“按下”PrtScrn键，而不是“释放”它。在此处添加第二行，如下所示：

Option Explicit

Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal _
  bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)

Private Const VK_SNAPSHOT = &H2C
Private Const KEYEVENTF_KEYUP = 2

Sub PrintScreen()
    keybd_event VK_SNAPSHOT, 1, 0, 0 'Key Down
    keybd_event VK_SNAPSHOT, 1, KEYEVENTF_KEYUP , 0 'Key Up
End Sub
然后，您可以将屏幕截图粘贴到工作表并将其导出为PDF

Sub SaveAsPDF()
    Const FILE_PATH as String = "C:\Temp\"
    PrintScreen 'Take a screenshot
    With Sheet1
        .Paste 'Paste it to Sheet1
        .ExportAsFixedFormat xlTypePDF, FILE_PATH & "Screenshot File.pdf" 'Export Sheet1 to PDF
    End With
End Sub
