Convert Binary-Integer in String to real Integer

Getting Started

Hello everyone,

how to convert a data type packed in a string back to its original type?

For example
The first 8 bytes of a string contain a UInt32 number:
B90D 0000 0000 0000 [Binary]

How can I make 3513 [Dec] out of it?

Here’s what I tried to do:

Dim mbc As MemoryBlock = StringRepresentationOfInteger
Dim mb As New Xojo.Core.MutableMemoryBlock( mbc, mbc.Size )
Dim tmp As UInt32
tmp = mb.UInt32Value(0)

It works, but is that the best way?

That looks more like an int64 to me (since every hex digit is 4 bits)
other than that endianess may be relevant but this is a reasonable way to do this

the conversion from old memory block to new memory block is an extra unnecessary step.

Your’re right. It’s UInt64, my fault.

You’re right. This works too:

Dim mbc As MemoryBlock = StringRepresentationOfInteger
Dim tmp As UInt64
tmp = mbc.UInt64Value(0)
