VBScript Reference Manual InduSoft Web Studio Replace Description Returns a string in which a specified substring has been replaced with another substring a specified number of times. Usage strVal = Replace(expression, find, replacewith[, start[, count[, compare]]]) Arguments expression Required. String expression containing substring to replace. find Required. Substring being searched for. replacewith Required. Replacement substring. start Optional. Position within expression where substring search is to begin. If omitted, 1 is assumed. Must be used in conjunction with count. count Optional. Number of substring substitutions to perform. If omitted, the default value is -1, which means make all possible substitutions. Must be used in conjunction with start. compare Optional. Numeric value indicating the kind of comparison to use when evaluating substrings. See Settings section for values. If omitted, the default value is 0, which means perform a binary comparison. Settings The compare argument can have the following values: Constant Value Description vbBinaryCompare 0 Perform a binary comparison. vbTextCompare 1 Perform a textual comparison Return A String. Replace returns the following values: If Replace returns expression is zero-length Zero-length string (""). expression is Null An error. find is zero-length Copy of expression. replacewith is zero-length Copy of expression with all occurrences of find removed. start > Len(expression) Zero-length string. count is 0 Copy of expression. Remarks The return value of the Replace function is a string, with substitutions made, that begins at the position specified by start and concludes at the end of the expression string. It is not a copy of the original string from start to finish See Also Left, LeftB, Len, LenB, LTrim, Mid, MidB, Right, RTrim, Trim Example Dim MyString Rem A binary comparison starting at the beginning of the string. MyString = Replace("XXpXXPXXp", "p", "Y") ' Returns "XXYXXPXXY". Rem A textual comparison starting at position 3. MyString = Replace("XXpXXPXXp", "p", "Y", 3, -1, 1) ' Returns "YXXYXXY". 152 InduSoft, Ltd.
InduSoft Web Studio VBScript Reference Manual RGB Description Returns a whole number representing an RGB color value Usage intVal = RGB(red, green, blue) Arguments red Required. Number in the range 0-255 representing the red component of the color. green Required. Number in the range 0-255 representing the green component of the color. blue Required. Number in the range 0-255 representing the blue component of the color. Remarks Application methods and properties that accept a color specification expect that specification to be a number representing an RGB color value. An RGB color value specifies the relative intensity of red, green, and blue to cause a specific color to be displayed. The low-order byte contains the value for red, the middle byte contains the value for green, and the high-order byte contains the value for blue. A runtime error occurs if any of the arguments cannot be evaluated to a numeric value. For applications that require the byte order to be reversed, the following function will provide the same information with the bytes reversed: Function RevRGB(red, green, blue) RevRGB= CLng(blue + (green * 256) + (red * 65536)) End Function Example MyColor = RGB(130, 155, 204) Right Description Returns length number of characters from the right side of a string Usage strVal = Right(string, length) Arguments string String expression from which the characters are extracted from. length Numeric expression indicating how many characters to return (extract). Remarks If string contains Null, Null is returned. If length is 0, a zero-length string("") is returned. If length is greater than or equal to the number of characters in string, the entire string is returned. To determine the number of characters in the string, use the Len function. See Also Left, LeftB, Len, LenB, Mid, MidB, RightB Example The following example uses the Right function to return a specified number of characters from the right side of a string: Dim AnyString, MyStr AnyString = "Hello World" 'Define string MyStr = Right(AnyString, 1) 'Returns "d" MyStr = Right(AnyString, 6) 'Returns " World" MyStr = Right(AnyString, 20) 'Returns "Hello World" RightB Description Returns length number of bytes from the right side of a string Usage strVal = Right(string, length) Arguments string String expression from which the bytes are extracted from. length Numeric expression indicating how many bytes to return (extract). Remarks If string contains Null, Null is returned. If length is 0, a zero-length string("") is returned. If length is greater than or equal to the number of bytes in the string, the entire string is returned. To determine the number of bytes in the string, use the LenB function.
