The CopyBytes function copies a specified number of bytes from one string to another string. You can specify the offset indices into the source and destination strings. CopyBytes is useful for working with binary files.
Syntax
CopyBytes ( svDest, nIndexDest, svSrc, nIndexSrc, nCount );
Parameters
|
Parameter |
Description |
|
svDest |
Specifies the destination string. |
|
nIndexDest |
Specifies the offset index (starting point) in the destination string at which location the bytes are to be inserted. The first byte in the string is at position 0. |
|
svSrc |
Specifies the source string. Do not pass an autosized string whose size is greater than 256 characters. Instead, declare the string with an explicit size. For more information about string sizing, see String Size and Autosize. |
|
nIndexSrc |
Specifies the offset index (starting point) in the source string at which location bytes begin to be copied. The first byte in the string is at position 0. |
|
nCount |
Specifies the total number of bytes you want to copy from svSrc to svDest. This value must be no larger than the size of svSrc - 1. For example, if svSrc was declared with a size of 512 (giving it a maximum string length of 511), then the value passed in nCount must be 511 or less. |
Return Values
