Delphi leaves the string unchanged if Index is not positive or greater than the number of characters after the Index. this leads to compiler warnings. But in new versions from Delphi 2010 it is Unicodestring / WideString. 1、 str:=stringof(bytes) Tbytes 为ansi编码 2、 str:=widestringof(bytes) Tbytes 为unicode编码. AnsiStringとstd::stringの比較(C++Builder2007以前) 文字列の比較 大文字と小文字を区別するとき. But strings passed by reference to a function or procedure (as var and out parameters) must be of the appropriate type. Strings are among the most frequently used data types. When the function adds value to str variable, an old Delphi compiler automatically converts Unicode string to an ANSI string, then adds the strings together and finally converts the new string from ANSI to Unicode. Delphi leaves the string unchanged if Index is not positive or greater than the number of characters after the Index. For Delphi 2009, a new UnicodeString type has been designed, that incorporates the capabilities of both the. So when i wanted to decode the string, i had to pass along the code-page with it:. By default, the unicode string will be converted to an ANSI encoding string, then be encoded into the barcode symbol. With the introduction of Unicode support in Delphi 2009 code gear changed the generic definitions of String, Char and PChar and while they still offer compiler switches to support old short string code (Delphi One string type) they did not provide a switch to support. lol, that ROCKS!!! Chi Happens "When you know and respect your own inner nature, you know where you belong. Delphi XE中String、ANSIString、TBytes之间的转换 一、string转为ansistring 1、直接赋值 (有警告) 2、ansistring()类型强制转换。(无警告) 二、ansistring 转为string 1、直接赋值 (有警告) 2、string()类型强制转换。. So, there's no way to get a non-1252 character to the method you're calling. That is why these can have any kind of method a Delphi string helper could implement too and helpers are not required. To make it simple, a type is a variable attribute. "long string" WideString = up to 2^30 chars (for use in Unicode or for COM interfaces) can set the length of a string by SetLength(s) can limit. This represent hundreds of thousands lines of code. The Delphi server would have to be changed (using WideString) to support that. s := PAnsiChar(Utf8Encode(TDataSet. String types can be mixed in assignments and expressions; the compiler automatically performs required conversions. It also contains Delphi version of attachments, docinfo, drawtoresource, encrypt, fromdoc, pagesperpage and sign examples, in a simplified form.
