Ms access 捕获和保存屏幕截图

因此，我试图让以下代码正常工作。我不再非常熟悉VBA/Access，因为我已经多年没有使用过它了。我正在使用access 2010，并提前就一些非常基本的问题向您道歉

我正在试着运行这个。我创建了一个模块，然后去调试，一开始我就得到了一个“复制选项语句”，突出显示了第一个“选项比较文本”

接下来，如何/在何处定义要保存的文件路径？如何启动屏幕截图？我是否必须通过每次按“播放”按钮从VBA运行此操作

谢谢，再次为初学者的问题道歉

'   *
'   * DESCRIPTION: Creates a standard Picture object from whatever is on the clipboard.
'   *              This object is then saved to a location on the disc. Please note, this
'   *              can also be assigned to (for example) and Image control on a userform.
'   *
'   * The code requires a reference to the "OLE Automation" type library.
'   *
'   * The code in this module has been derived from a number of sources
'   * discovered on MSDN, Access World Forum, VBForums.
'   *
'   * To use it, just copy this module into your project, then you can use:
'   * SaveClip2Bit("C:\Pics\Sample.bmp")
'   * to save this to a location on the Disc.
'   * (Or)
'   * Set ImageControl.Image = PastePicture
'   * to paste a picture of whatever is on the clipboard into a standard image control.
'   *
'   * PROCEDURES:
'   *   PastePicture  :   The entry point for 'Setting' the Image
'   *   CreatePicture :   Private function to convert a bitmap or metafile handle to an OLE reference
'   *   fnOLEError    :   Get the error text for an OLE error code
'   *   SaveClip2Bit  :   The entry point for 'Saving' the Image, calls for PastePicture
'   *   AltPrintScreen:   Performs the automation of Alt + PrtScrn, for getting the Active Window.
'   *   Pause         :   Makes the program wait, to make sure proper screen capture takes place.
