Problem Statement

Currently, WAM returns error code in decimal, resulting in negative numbers, such as -2147023584, -2147221164. Their corresponding hexadecimal values are 0x80070520, 0x80040154.

Even https://aka.ms/errors recommends using hex:

🤔 Inverting error code: query was -2147221164 which is more commonly expressed as 0x80040154.

In a search engine, - usually means "not to include". Searching for -2147221164 gives no result:

Proposed solution

WAM should return error code in hexadecimal.

[jiasli]

The minus sign - is in those error codes does not really mean negative numbers. It is due to treating memory bytes as signed integers.

To convert theme back, we can use below Python code:

print((-2147023584).to_bytes(4, signed=True).hex())
print((-2147221164).to_bytes(4, signed=True).hex())

# output
80070520
80040154
