ShortString保留该类型是为了向后兼容Delphi1.0,它的长度限制在255个字符内。 WideString功能上类似于AnsiString,但它是由WideChar字符组成的。 PChar指向null结束的Char字符串的指针,类似于C的char*或lpstr类型。 PAnsiChar指向null结束的AnsiChar字符串的指针。 PWideChar指向null结束的WideChar字符串的指针。 缺省情况下...
接下来,我就详细讲讲`stringtowidechar`可能涉及的参数。 1. 输入字符串参数:这是`stringtowidechar`函数的核心输入之一。它代表着需要被转换为宽字符字符串的普通字符串。通常,这个字符串的类型取决于所使用的编程语言。例如在C++中,可能是`const char*`类型,表示一个以空字符`'\0'`结尾的普通字符数组。这个...
函数讲str转换成一个宽字符串，它将size-1个字符串从str复制到Result中，并在其后补充#0。procedure Demo;var OleStr:PwideChar;begin GetMem(OleStr,(Length(S)+1)*SizeOf(WideChar));try StringToWideChar(s,OleStr,Length(S)+1);SomeOLEProcedure(OleStr);finally FreeMem(OleStr);end;end;
function TranslateDBFile(Str: string): string; var tmp: UTF8String; l: Integer; l_WideString: PWideChar; l_Length: Integer; begin if IsEnglishString(Str) then Result := Str else begin l_Length := Length(Str) * 2; GetMem(l_WideString, l_Length); StringToWideChar(Str, l_WideString, ...
