可以使用VBA代码通过调用Windows API函数来实现在Excel VBA窗体中插入图片背景。具体实现方式可以参考以下代码:
Private Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" (ByVal uAction As Long, ByVal uParam As Long, ByVal lpvParam As Any, ByVal fuWinIni As Long) As Long
Private Const SPI_SETDESKWALLPAPER = 20
Private Const SPIF_UPDATEINIFILE = &H1
Sub SetWallpaper(ByVal sWallpaperPath As String)
Dim lResult As Long
lResult = SystemParametersInfo(SPI_SETDESKWALLPAPER, 0&, sWallpaperPath, SPIF_UPDATEINIFILE)
End Sub
可以先将图片插入到一个隐藏的Sheet中,然后将该Sheet的背景设置为透明色,最后将该Sheet作为窗体的背景。具体实现方式可以参考以下代码:
Private Sub UserForm_Initialize()
Dim sWallpaperPath As String
sWallpaperPath = "C:\images\background.jpg"
SetWallpaper sWallpaperPath
Me.BackColor = RGB(0, 0, 0)
Me.TransparencyKey = RGB(0, 0, 0)
Me.PictureSizeMode = fmPictureSizeModeZoom
Me.Picture = ThisWorkbook.Sheets("Background").Shapes("Background").Picture
End Sub
其中,"Background"为隐藏的Sheet名称,"Background"为该Sheet中插入的图片名称,"fmPictureSizeModeZoom"为图片缩放模式,可以根据需要进行修改。
