I am currently maintaining a website that was developed using Visual Basic and my problem is that this web application I am currently maintaining or supporting has the following error.
Error 38 'DirList' is not a member of 'TigerBrandsIntranet.Lounge_Image_Library'. C:\Users\Wise\Desktop\Tiger(Intranet)\BackUp of TBIntranet\TBIntranet\Lounge\Image Library.aspx.vb 111 9 TigerBrandsIntranet
This is the code of the page that's giving me problems.
I would appreciate it so much if there's someone who can assist with this error.
