Implicit string conversion is very common in VB, and you often have no idea it has actually happened However, string conversion is expensive and you should avoid it when possible There are some simple steps you can take to minimize the number of string conversions The first step is to use the W versions of the Asc and Chr$ functions Asc must first convert a native UNICODE string into ANSI before it returns the value; AscW simply reads the number currently stored in the string Similarly, Chr$ must convert the number you give it into a UNICODE number The result is that AscW and ChrW$ are much faster than Asc and Chr$ You should always use the $ versions of string functions whenever they are available If a $ version of a function is available, then its non counterpart actually returns a Variant rather than a String Although the VB compiler is smart enough to avoid duplicating the string when assigning the return value of a Variant function to a String variable, a significant amount of overhead and code generation is involved in using the non-$ functions If you think the extra character is too much trouble, one look at the generated code will cure your laziness Search for $ in the Object Browser to get a list of the $ functions The best-known place where VB performs automatic ANSI/UNICODE conversion is when you send String or fixed-length string variables to Declare functions To seamlessly handle an external world that is often ANSI from within an internal world that is always UNICODE, the VB brain trust decided that all API calls would be considered ANSI When you want an ANSI API call, this situation is wonderful from a coding perspective because you don't have to do any work to make an ANSI API call from VB But from a performance perspective, you add string-conversion overhead at runtime If you write an application exclusively for Windows NT or Windows 2000, which have full UNICODE API support, string conversions for API calls are a waste The downside of implicit conversion is that there is no way to make a Declare statement treat all strings as UNICODE and leave them alone Articles in the VB4 timeframe advocated a ridiculously heavy and complex workaround for calling UNICODE API functions The technique involved copying strings to and from Byte arrays and passing the first element of the Byte array ByRef to the API.

may be given negative values, in which case the index is taken from the end of the string The stranslate() method is used to perform advanced character substitutions such as quickly stripping all control characters out of a string As an argument, it accepts a translation table containing a one-to-one mapping of characters in the original string to characters in the result For 8-bit strings, the translation table is a 256-character string For Unicode, the translation table can be any sequence object s where s[n] returns an integer character code or Unicode character corresponding to the Unicode character with integer value n The sencode() and sdecode() methods are used to transform string data to and from a specified character encoding As nput, these accept an encoding name such as 'ascii', 'utf-8', or 'utf-16'These methods are most commonly used to convert Unicode strings into a data encoding suitable for I/O operations and are described further in 9, Input and Output Be aware that in Python 3, the encode() method is only available on strings, and the decode() method is only available on the bytes datatype The sformat() method is used to perform string formatting As arguments, it accepts any combination of positional and keyword arguments Placeholders in s denoted by {item} are replaced by the appropriate argument Positional arguments can be referenced using placeholders such as {0} and {1} Keyword arguments are referenced using a placeholder with a name such as {name} Here is an example:.

With flags to print line numbers of matched lines, count matches, do caseinsensitive matching, invert the sense (select lines that don't match the pattern), and perform other variations of the basic idea, grep is so widely used that it has become the classic example of tool-based programming Unfortunately, not every system comes with grep or an equivalent Some systems include a regular expression library, usually called regex or regexp, that you can use to write a version of grep If neither option is available, it's easy to implement a modest subset of the full regular expression language Here we present an implementation of regular expressions, and grep to go along with it; for simplicity, the only metacharacters are A $ and a, with a specifying a repetition of the single previous period or literal character This subset rovides a large fraction of the power with a tiny fraction of the programming complexity of general expressions Let's start with the match function itself Its job is to determine whether a text string matches a regular expression:.

In spite of the formidable uncertainty and an immense diversity of possible obstacles and scenes, a good number of algorithms discussed above guarantee convergence: That is, a mobile robot equipped ith one of these procedures is guaranteed to reach the target position if the target can in principle be reached; if the target is not reachable, the robot will make this conclusion in nite time. The algorithms guarantee that the paths they produce will not circle in one area an inde nite number of times, or even a large number of times (say, no more than two or three). Twenty years ago, most specialists would doubt that such results were even possible. On the theoretical level, today s results mean, to much surprise from the standpoint of earlier views on the subject, that purely local input information is not an obstacle to obtaining global solutions, even in cases of formidable complexity. Interesting results raise our appetite for more results. Answers bring more questions, and this is certainly true for the area at hand. Below we discuss a number of issues and questions for which today we do not have answers.

These two hex digits consist of the value that can be mapped into the ASCII (for English language) table to get the character For example, %20 (hex) is 32 ( decimal) and maps to the space character in the SCII table.There are two ways in which Apache can implement support for CGI The standard Apache distribution includes a CGI module that implements the traditional CGI support; however, there is a new module (FastCGI) that implements support for high-performance CGI applications This section discusses the standard CGI support issues In the previous sections, you learned that a CGI-compliant Web server uses environment variables, standard input (STDIN) and standard output (STDOUT) to transfer information to and from CGI programs Apache provides a flexible set of environment variables for the CGI program developers Using these environment variables, a CGI program not only retrieves input data, but also recognizes the type of client and server it is dealing with In the following sections, I discuss the environment variables that are available from the tandard CGI module compiled into Apache. 12 Running CGI Scripts.
