Since both are inside the MS Platform, i don't think that it took that much changes (Since i doesn't have any working knowladge on this type of migrations)

hi frds

i have downloaded a sampl vj++ application and then converted to c# using the JLCA but when i run the new application its giving error

" using Variant = com.ms.com.Vari ant;" this was the stmt in vj++

in c# how to convert this mannually

i wrote in c# as below but still i'm getting errors

using Variant = System.Runtime. InteropServices ;

what is the equivalent class in c# for this" using Variant = com.ms.com.Vari ant; "

and other error is "can't convert int[] to out int "

how to fix these bugs.its very urgent

thanks u

Hi Archu,
For variants there is no equivalent available in .NET since its strong typed (As of my knowledge). You have to cast of your own to achieve this.

Thanks.
