Used at the module level to declare the default comparison method to use vba option compare database expected text or binary string data is compared. Option Compare { Binary Text Database }. If used, the Option Compare statement must appear in a module before any procedures. The Option Compare statement specifies the string comparison method BinaryTextor Database for a module. If a module doesn't include an Option Compare statement, the default text comparison method is Binary.

Option Compare Binary results in string comparisons based on a sort order derived from the internal binary representations of the characters. In Microsoft Windows, sort order is determined by the code page. A typical binary sort order is shown in the following example:. Option Compare Text results in string comparisons based on a case-insensitive text sort order determined by your system's locale. When the same characters are sorted by using Option Compare Textthe following text sort order is produced:.

Option Compare Database can only be used within Microsoft Access. This results in string comparisons based on vba option compare database expected text or binary sort order determined by the locale ID of the database where the string comparisons occur. This example uses the Option Compare statement to set the default string comparison method. When Option Compare isn't used in a module, the default comparison method is binary. When Option Compare is used, it must appear at the start of the module's declarations section, before any procedures.

Binary comparison —the default text comparison method in Visual Basic—uses the internal binary code of each character to determine the sort order of the characters. Text comparison uses the locale settings of the current system to determine the sort order of the characters. Optimization: If 1 of the strings is already in lower or upper case, information technology is plenty to catechumen the other. To encounter whether a longer piece of text is 1 of given alternatives, call the post-obit kind of code:.

This test tells us if "AB" is i of "AB", "CD" or "EF". Notation the utilize of separators, "-" in this example. If yous desire to find the due north th occurrence of a cord, non merely the first 1, set northward to the desired number and run the following code:. The loop keeps searching until the north th occurrence is found or there was no match.

position tells the result. Each loop iteration performs a examination on each finding. The loop exits when the test condition is met or when there are no more matches. The test will typically examine the found position to see whether it contains an acceptable value or non.

You tin can apply more complex tests such every bit the Similar operator, tests that you cannot incorporate in the InStr telephone call. In the above instance, the test could determine whether "vb" is a word or a function of a longer word.

What comes to pure functioning, InStr ,,,vbBinaryCompare is a quick function. Its counterpart InStr ,,,vbTextCompare is very slow. It actually pays off to utilize vbBinaryCompare with InStr. You can use the start parameter to optimize InStr. Use start to skip the beginning of the string when y'all know the match must exist somewhere farther in the cord.

For InStr performance details, please read Optimize string handling in VB6, Part Ii. InStrRev searches the string in opposite order: from the end to the start. It locates the concluding occurrence of a cord inside another.

Note how the parameters are in a different club than with InStr. Also note that InStrRev does not contrary the input strings: "ABC" does not lucifer "CBA". InStrRev runs slowly, especially on a long string1.

Utilise InStr when y'all tin can. More than. InStrB treats the input and search strings as byte arrays, non equally regular strings. Every bit you may know, VB uses Unicode strings. InStrB lets y'all by-laissez passer Unicode functionality and use byte arrays as if they were strings. Instead of character position, InStrB returns the byte position of string2 in string1.

InStrB should not exist used for regular string processing. InStrB is relatively fast and information technology tin can exist used for optimization, but it'due south tricky.
