Returns a value indicating the result of a string comparison.
StrComp(string1, string2[, compare])
The compare argument can have the following values:
Constant | Value | Description |
---|---|---|
vbBinaryCompare | 0 | Perform a binary comparison. |
vbTextCompare | 1 | Perform a textual comparison. |
The StrComp function has the following return values:
If | StrComp returns |
---|---|
string1 is less than string2 | -1 |
string1 is equal to string2 | 0 |
string1 is greater than string2 | 1 |
string1 or string2 is Null | Null |
The following example uses the StrComp function to return the results of a string comparison. If the third argument is 1, a textual comparison is performed; if the third argument is 0 or omitted, a binary comparison is performed.
Dim MyStr1, MyStr2, MyComp MyStr1 = "ABCD": MyStr2 = "abcd" ' Define variables. MyComp =StrComp(
MyStr1,
MyStr2,
1)
' Returns 0. MyComp =StrComp(
MyStr1,
MyStr2,
0)
' Returns -1. MyComp =StrComp(
MyStr2,
MyStr1)
' Returns 1.
