BufferToHexa (Function)

In french: BufferVersHexa

Converts a buffer into a displayable hexadecimal string (for example: "4A 5B 00").

This function is mainly used to check the content of a buffer byte by byte.

Note: To convert an hexadecimal string into buffer, use HexaToBuffer .

EDT_DUMP = BufferToHexa(s)

s is UNICODE string = "abdcefghijkl"

Syntax

<Result> = BufferToHexa(<Buffer to Convert> [, <Nb Bytes per Word> [, <Nb Bytes per Line>]])

<Result>: Character string

Character string in hexadecimal format.

<Buffer to Convert>: Buffer

Buffer to Use. This parameter can also correspond to an Ansi or Unicode string.

<Nb Bytes per Word>: Integer or Integer constant

Number of bytes displayed per word. This parameter can correspond to:
1 (default value): the values are grouped by byte.
2: the values are grouped by word of 2 bytes.
4: the values are grouped by double word of 4 bytes.
Versions 23 and later
the NoGrouping constant: no grouping will be done. All hexadecimal codes will be pasted. Example: 61002345A1.
New in version 23
the NoGrouping constant: no grouping will be done. All hexadecimal codes will be pasted. Example: 61002345A1.
the NoGrouping constant: no grouping will be done. All hexadecimal codes will be pasted. Example: 61002345A1.

<Nb Bytes per Line>: Integer or Integer constant

Number of bytes displayed before going to the next line.
After each <Nb Bytes Per Line> a carriage Return (CR) is added to the result string.
If <Nb Bytes Per Line> is les than <Nb Bytes Per Word>, the Carriage Return (CR) character will be added every <Nb Bytes Per Word>.
Versions 23 and later
If this parameter corresponds to the NoLine constant, all bytes will be positioned on the same line.
New in version 23
If this parameter corresponds to the NoLine constant, all bytes will be positioned on the same line.
If this parameter corresponds to the NoLine constant, all bytes will be positioned on the same line.
By default:
this number is equal to 16.
the grouping is performed in Little-Endian format (high bytes at the end, like in x86).
Versions 23 and later
if <Nb Bytes per Word> is set to NoGrouping, then <Nb Bytes per Line> will correspond to the NoLine constant by default.
New in version 23
if <Nb Bytes per Word> is set to NoGrouping, then <Nb Bytes per Line> will correspond to the NoLine constant by default.
if <Nb Bytes per Word> is set to NoGrouping, then <Nb Bytes per Line> will correspond to the NoLine constant by default.
To group value in Big-endian format:
use the BigEndian constant.
add the BigEndian constant to the <Nb Bytes per Line> value.
Versions 23 and later
Note: the NoLine constant and the BigEndian constant can be combined.
New in version 23
Note: the NoLine constant and the BigEndian constant can be combined.
Note: the NoLine constant and the BigEndian constant can be combined.
