Delphi判断进程是否存在（使用CreateToolhelp32Snapshot）

 

program Project2;

uses
  windows,TLHelp32;

function FindProcess(AFileName:string):boolean;
var
    hSnapshot:THandle;
    lppe:TProcessEntry32;
    Found:Boolean;
begin
    Result:=False;
    hSnapshot:=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
    lppe.dwSize:=SizeOf(TProcessEntry32);
    Found:=Process32First(hSnapshot,lppe);
while Found do
begin
    if(lppe.szExeFile = AFileName) then Result:=True;
    Found:=Process32Next(hSnapshot,lppe);
end;
end;

begin
    if FindProcess('QQ.exe') then
    MessageBox(0, PChar('QQ存在'), PChar('提示'), MB_OK);
end.
