Extract a substring from a string, using strong typing and three required arguments — both the substring and the string can contain double-byte characters.

Namespace: XSharp.VO
Assembly: XSharp.VO (in XSharp.VO.dll) Version: 2.21

Syntax

Copy

 FUNCTION MBSubstr3(
	cMBTarget AS STRING,
	wStart AS DWORD,
	wCount AS DWORD
) AS STRING

public static string MBSubstr3(
	string cMBTarget,
	uint wStart,
	uint wCount
)

Parameters

cMBTarget: Type: String
The string from which to extract a substring.
wStart: Type: DWord
The starting position relative to the leftmost character in cMBTarget.
wCount: Type: DWord
The number of characters to extract — double-byte characters count as one character.
If wCount is greater than the number of characters from wStart to the end of cMBTarget, the extra is ignored.

Return Value

Type: String
The substring.
If the substring is not present, or if you specify wStart as zero, MBSubstr3() returns a NULL_STRING.

Remarks

MBSubstr3() is a typed version of MBSubstr() in which all three arguments are required. Because wStart cannot be negative, MBSubstr3() cannot extract a substring relative to the rightmost character of cMBTarget as can MBSubstr().

Remarks

Tip
This function is the same as Substr3() since .Net has unicode strings
