如何从Delphi6迁移到Delphi2010(Unicode问题)
您好,我在 Delphi 6 中使用了 Francois Piette 的 RasDial,但它在 Delphi 2010 中停止工作 如何才能像以前一样继续使用这些功能?
class function Encryption.DecriptPasswd(strPasswd: string): string;
type
PWORD = ^WORD;
var
Buffer : String;
PW : String[255];
P : PWORD;
I : Integer;
V : Integer;
begin
PW := ' ';
P := PWORD(@PW[0]);
I := 1;
while I <= Length(strPasswd) do
begin
Buffer := Copy(strPasswd, I, 5);
I := I + 5;
V := StrToInt(Buffer) - 34567;
P^ := V;
Inc(P);
end;
Result := PW;
end;
class function Encryption.EncriptPasswd(strPasswd: string): string;
type
PWORD = ^WORD;
var
Len : Integer;
I : Integer;
V : DWORD;
P : PChar;
Buffer : String[255];
begin
Buffer := strPasswd;
Len := Length(Buffer) + 1;
if (Len mod 2) <> 0 then
Inc(Len);
if Len < 10 then
Len := 10;
I := Length(Buffer);
if I = 0 then
Buffer := IntToStr(GetTickCount)
else
while Length(Buffer) < 10 do
Buffer := Buffer + Buffer;
SetLength(Buffer, I);
Result := '';
P := PChar(@Buffer[0]);
for I := 1 to Len div 2 do
begin
V := 34567 + PWORD(P)^;
P := P + 2;
Result := Result + Format('%5.5d', [V]);
end;
end;
Hi I was using the Francois Piette's RasDial with Delphi 6, but it stopped working in Delphi 2010
How can I keep using these functions like before?
class function Encryption.DecriptPasswd(strPasswd: string): string;
type
PWORD = ^WORD;
var
Buffer : String;
PW : String[255];
P : PWORD;
I : Integer;
V : Integer;
begin
PW := ' ';
P := PWORD(@PW[0]);
I := 1;
while I <= Length(strPasswd) do
begin
Buffer := Copy(strPasswd, I, 5);
I := I + 5;
V := StrToInt(Buffer) - 34567;
P^ := V;
Inc(P);
end;
Result := PW;
end;
class function Encryption.EncriptPasswd(strPasswd: string): string;
type
PWORD = ^WORD;
var
Len : Integer;
I : Integer;
V : DWORD;
P : PChar;
Buffer : String[255];
begin
Buffer := strPasswd;
Len := Length(Buffer) + 1;
if (Len mod 2) <> 0 then
Inc(Len);
if Len < 10 then
Len := 10;
I := Length(Buffer);
if I = 0 then
Buffer := IntToStr(GetTickCount)
else
while Length(Buffer) < 10 do
Buffer := Buffer + Buffer;
SetLength(Buffer, I);
Result := '';
P := PChar(@Buffer[0]);
for I := 1 to Len div 2 do
begin
V := 34567 + PWORD(P)^;
P := P + 2;
Result := Result + Format('%5.5d', [V]);
end;
end;

您可以首先将所有
string
声明(除了已经存在的string[255]
声明)更改为AnsiString
,所有Char
到AnsiChar
,所有PChar
到PAnsiChar
。然后前往此处查看有关将 Unicode 之前版本的 Delphi 移植到统一码。它们的作者是 Nick Hodges,Delphi 是 CodeGear 产品时的前产品经理。它们涵盖了更改其他现有代码所需的所有详细信息。
You can start by changing all
string
declarations (except thestring[255]
ones, which already are) toAnsiString
, allChar
toAnsiChar
, and allPChar
toPAnsiChar
.Then go here for the first in a series of three articles on porting pre-Unicode versions of Delphi to Unicode. They're really well written by Nick Hodges, former Product Manager for Delphi when it was a CodeGear product. They cover all the details you need to make the changes to your other existing code.
String[255] 是短字符串(一个字节)
但是当你添加 pchar 时,它会增长两个字节乘两个字节
尝试用 pansichar 替换 pchar
String[255] is short string (one byte)
but when you add pchar, it grows two bytes by two bytes
try replace pchar by pansichar
