Checking for File Exist

sibin_jacob — Fri, 20 Nov 2020 18:02:30 GMT

HI,

In my application I am using document chaining. 3 qvw files in my application.

1.Intro.qvw

2.Geo.qvw

3.Phy.qvw

In my Intro.qvw file contains two buttons.one for Geo & another for Phy view.

All the files are present in 'C:\ss' folder.

If geo file is not present in this folder I need to hide the geo button.

Is there any way to hide button if the corresponding file not exist ?

Thanks

Sibin

You can't use QVDCREATETIME since that checks for a QVD not a QVW. The only way I know of to do this (without macros), is to set a variable in the script using function filesize() which is a script-only function. Assuming your application hasn't been deleted since the last reload, that should work for you.

Regards,

Vlad
