请问如何kill一个已经运行的程序。

[halloo]

就是说程序2运行开始的时候，杀掉程序1。怎么写？谢谢。

找到它的句柄，发消息，WM_CLOSE

[halloo]

HWND hWnd;
if((hWnd = FindWindow(NULL,"pro1")) != NULL){
CloseHandle(hWnd);
}
是这样吗？但是好像没有不行。能给出代码吗？

include <vcl.h>
#pragma hdrstop
#include "tlhelp32.h"

#include "Unit1.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
TForm1 *Form1;
//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
}
//---------------------------------------------------------------------------

void __fastcall TForm1::Button1Click(TObject *Sender)
{
DWORD pID;
bool rValue;
PROCESSENTRY32 lppe;
HANDLE hSnapshot;
HANDLE pHandle;
hSnapshot=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
lppe.dwSize = sizeof(lppe);
rValue=Process32First(hSnapshot,&lppe);
TListItem *NItem;

ListView1->Items->Clear();
while(rValue)
{
if(UpperCase(ExtractFileName(lppe.szExeFile))=="QQ2000B.EXE")//Kill QQ2000.EXE
{
pID=lppe.th32ProcessID; //在此得到进程的ID
pHandle=OpenProcess(PROCESS_TERMINATE,false,pID);
TerminateProcess(pHandle,-9); //Kill该进程
}
NItem=ListView1->Items->Add();
NItem->Caption=lppe.th32ProcessID;
NItem->SubItems->Add(String(lppe.szExeFile));
rValue=Process32Next(hSnapshot,&lppe);

}
CloseHandle(hSnapshot);

}

或是
HWND Wnd=FindWindowEx(NULL,NULL,NULL,"your program's title");
if (Wnd!=0)
{ ::SendMessage(Wnd,WM_SYSCOMMAND,SC_CLOSE,0);
::SendMessage(Wnd,WM_CLOSE,0,0);
}

[叶子哟]

前者肯定可以，后者必须是它接受这个消息

谢谢。
