在excel VBA中使用发送键打开后，如何在继续之前检查文件是否已经打开？

Question

I am opening a file from a website. After I send sendkeys "%{O}", I need the file to be opened first before proceeding. If I add wait times or loops after the sendkeys, the file wont open until after those loops. Kindly note that I don't know the name or location of the file, I just opened it from a path given to me.

I have already tried putting Application.Wait, creating a sub that just counts and using this between opening and writing to the worksheet.

Application.SendKeys "%{O}" 'opens the workbook from IE
Set wb2 = ActiveWorkbook.Worksheets("Needed_Worksheet")
wb2.Cells(1,1) = "HELLO"

I expect to write on the first cell of the newly opened workbook.

Answer 1

This is working now using Sleep:

#If VBA7 Then
    Public Declare PtrSafe Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As LongPtr) 'For 64 Bit Systems
#Else
    Public Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long) 'For 32 Bit Systems
#End If

Then call:

Sleep 20000

Thanks @DavidZemens for the suggestion
