Delphi 服務程式[7] 呼叫外部程式的方法：

Function GetProcessHandleAsName(Name:String):THandle;       //獲取程序控制代碼
Var
    Hd,Hs:THandle;
    dExit:Cardinal;
    Tmp,Tmp1:String;

begin
    Result:=0;
    Lp.dwSize:=sizeof(TProcessEntry32);
    Hd:=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
    if Process32First(Hd,Lp) then
        Repeat
            Tmp:=UpperCase(Trim(Name));
            Tmp1:=Trim(UpperCase(Lp.szExeFile));
            if AnsiPos(Tmp,Tmp1)>0 then
            begin
                Result:=OpenProcess(PROCESS_ALL_ACCESS,true,Lp.th32ProcessID);
                break;
            end
        Until Process32Next(Hd,Lp)=False;
end;

procedure CreateProc(const ProcessName:String);       //建立/開啟外部程式
Var
    siStartupInfo:STARTUPINFO;
    saProcess,saThread:SECURITY_ATTRIBUTES;
    piProcInfo:PROCESS_INFORMATION;
    Hd:Cardinal;
    ProcessHd:THandle;
    Hds:THandle;
    Str:String;
