I am using VB .net and integrating the third party dll to my code which is related to keycard in Hotel software.

So the key-card is generated for the particular floor the guest check in. for that in their documentation they asked to format it as 32 bit character string.

Ex: If the guest is in 17 the floor then the

Dim FloorSelection as string = "00000000000000010000000001000000"

From left 1 should be added in place of 7 for each floor and 1 should be added to the floor the guest checkin

What I have tried:

so how can i achieve this based on their criteria to add 1 to the particular place based on the guest check in floor

It's not easy to tell from just that one example - you really need to go back to the documentation and double check exactly how the string it supposed to relate to the floor and room number, as it seems unlikely that it's what it appears from that.
Best guess:

00000000000000010000000001000000

Is in two parts:

0000000000000001  -  floor number (1)
0000000001000000  -  room on floor (7)

But that restricts the system to only work with 16 rooms per floor, and I've stayed in hotels with far, far more than that!

But the simplest way to do this conversion is to set up an array:

VB

Private toBinaryString As String() = {"0000000000000001", "0000000000000010", "0000000000000100", "0000000000001000", "0000000000010000", "0000000000100000", "0000000001000000", "0000000010000000", "0000000100000000", "0000001000000000", "0000010000000000", "0000100000000000", "0001000000000000", "0010000000000000", "0100000000000000", "1000000000000000"}

and then use the floor number and room number as indexes to get each "half" of the string you need.

But I'd strongly advise you to read the documentation carefully before committing yourself on this!
