Automatic Export with VBScript - WinCC 6.2

I have a WinCC picture with four trends. Each trend has a hotkey linked to the csv export function. I am trying to write a script that will sequentially activate each trend and press the appropriate hotkeys, in order to export all trends.

The first trend is exported successfully, but subsequent trends are not. Here is my code:

may be the sleep time is too less. export of first control is not over and hotkey is pressed for the second and so on.

increase the delay time and  check

 I have tried delay value as high as 3 seconds, which is about as long as I waited when testing the hotkeys manually, so I don't think this is the problem.

I have also tried inserting some code after the first hotkey is pressed, and it does not appear to run. My best guess is that the process of exporting the data is interrupting the script.

I have found the solution to the problem: WScript.Sleep only works in the Windows Script Host environment (Source). My solution is to instead use a workaround with a Timer object:

I have tested this with Notepad; I will update this post when I have tested with WinCC. Feel free to add alternative solutions, since my code is a bit clunky.

Update: It worked! The time delay can be decreased to 1 second. The issue was just that using WScript.Sleep was causing a runtime error.

Dear Indalco1;

I have tested your sub prog and its working. Thank you so much for your help.
