杀死自己的进程再重新启动自己
全部源代码如下（无窗体结构，最后面有说明）：
program Project1;
uses
Winprocs,SysUtils,Tlhelp32;//注意添加单元文件
function KillTask(ExeFileName:string):integer;//杀进程函数KillTask
const
PROCESS_TERMINATE = $0001;
var
ContinueLoop: BOOLean;
FSnapshotHandle: THandle;
FProcessEntry32: TProcessEntry32;
begin
Result :=0;
FSnapshotHandle := CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
FProcessEntry32.dwSize := SizeOf(FProcessEntry32);
ContinueLoop := Process32First(FSnapshotHandle, FProcessEntry32);
while Integer(ContinueLoop) <> 0 do
begin
if ((UpperCase(ExtractFileName(FProcessEntry32.szExeFile)) =
UpperCase(ExeFileName)) or (UpperCase(FProcessEntry32.szExeFile) =
UpperCase(ExeFileName))) then
Result := Integer(TerminateProcess(
OpenProcess(PROCESS_TERMINATE,
BOOL(0),
FProcessEntry32.th32ProcessID),0));
ContinueLoop := Process32Next(FSnapshotHandle, FProcessEntry32);
end;
CloseHandle(FSnapshotHandle);
end;
//调用上面的函数KillTask
begin
//杀进程，停止程序
KillTask('abc.exe');//调用函数，杀你的程序abc.exe
//重新启动程序
WinExec('abc.exe',SW_SHOW);//然后再重新启动abc.exe
Exit;
end.
