Hi priyanka, don't repeat your posts, that triggers the system into flagging a hack attack.

The .aia file you posted had no CloudDB component in it, but tried to use CloudDB blocks.
How did you do that?

some blocks
some blocks1053×362 44.3 KB
Designer
Designer783×270 41.5 KB

....probably by inserting the Blocks via the Backpack

i got my solution thanks !!

11

Can you share your solution to help other forum members?

12

sir its an i am not using the cloud component over there i dont know how its miss from me ..the solution is this only i have to add component of cloud db in designer !!

13

OK :grin:

Thanks for getting back to us. There are two ways to get a disconnect between the Designer and the Blocks:

  1. Insert Blocks via the Backpack from elsewhere
  2. Use 'UnDo' in the Blocks work Area

i have 1 doubt if i want to make same app..then there is any short method ?

16

If you mean you want to make a similar App, just use Save Project As to make a new one from the existing one.
