void CtestfunDlg::OnBnClickedButton1()
{
// TODO: 在此添加控件通知处理程序代码

OutputDebugString(L"start#############\r\n");

ShellExecute(NULL ,L"open",L"e:/abc.txt",0,0,SW_SHOW);

OutputDebugString(L"end#############\r\n");

}
When i quickly click the button ,i think the correct output is:
start#########,end###########,start#########,end###########

But the program actual output is start#########,start#########,end###########,end###########,why?
