Question:
How do I use UIDs allocated from www.symbiansigned.com?
I am not sure exactly how to use the UIDs in my application allocated to me. What are the letters for?

Answer:
Most UIDs in Symbian OS are represented using hexadecimal symbols. Hexadecimal is a numerical system with a radix or base of 16 written using the symbols 0–9 and A–F. You can find more information on hexadecimal (and how to convert between hexadecimal and decimal representations) on the internet – e.g., http://en.wikipedia.org/wiki/Hexadecimal.

Symbian Signed (www.symbiansigned.com) allocates UIDs as a range of hexadecimal values. The portal will always allocate the UIDs in a range – even if only one UID is requested. This applies to both protected and unprotected UIDs. For example:

In order to use the UIDs in your application, you need to split the range allocated from the portal into individual hexadecimal UIDs, and copy/paste each new UID value in your application where appropriate e.g. .pkg, .mmp files, font definitions, ECOM resource files etc., or within the application itself.

If you are unfamiliar with hexadecimal values the easiest way to get the range as a set of individual UIDs is to convert the start and end values of the UID range into decimal using a scientific calculator. You can then easily fill in the intermediate UID values in the range in decimal. When you need a new UID, simply convert the next decimal value in your range to hexadecimal and use it in your program.

For demonstration only, the tables below show several ranges as individual UIDs, both in hexadecimal and decimal.

UID Range : 0x20000087 - 0x20000087 (1 UID)
Number	Hexadecimal representation	Decimal representation
1	0x20000087	536871047

UID Range : 0x20000037 - 0x20000039 (3 UIDs)
Number	Hexadecimal representation	Decimal representation
1	0x20000037	536870967
2	0x20000038	536870968
3	0x20000039	536870969

UID Range : 0x20000088 - 0x2000008C (5 UIDs)
Number	Hexadecimal representation	Decimal representation
1	0x20000088	536871048
2	0x20000089	536871049
3	0x2000008A	536871050
4	0x2000008B	536871051
5	0x2000008C	536871052

UID Range : 0x2000008D - 0x20000096 (10 UIDs)
Number	Hexadecimal representation	Decimal representation
1	0x2000008D	536871053
2	0x2000008E	536871054
3	0x2000008F	536871055
