需要滚动滚动usercontrol(Need to mousewheel scroll a usercontrol)

 它看起来像你： 
 
 
 
 在Windows上 
 
 
 试图异步启动外部程序 
 
 
 这是允许您这样做的秘诀： 
 
function async_exec_win($cmd)
{
    $wshShell = new COM('WScript.Shell');
    $wshShell->Run($cmd, 0, false); // NB: the second argument is meaningless
                                    // It just has to be an int <= 10
}
 
 这需要COM类可用于您的PHP实例，您可能需要在php.ini中启用extension=php_com_dotnet.dll （自PHP 5.3.15 / 5.4.5起）以使其可用。 
 
 另请注意，这将需要您要执行的文件的完整文件名 ，因为扩展名搜索列表不会在cmd.exe外部使用。 因此，而不是srcds -console ...你需要srcds.exe -console ... - 我个人不喜欢chdir()方法，我宁愿将exe的完整路径传递给函数 -但是如果这样做，则需要确保目录分隔符的操作系统类型正确。 PHP会让你随心所欲地使用任何你喜欢的东西，操作系统也不会那么宽容。 
 
 为了完整起见，这里是如何在* nix上做类似的事情。 这实际上比Windows版本更好，因为它还返回创建的进程的PID： 
 
function async_exec_unix($cmd)
{
    return (int) exec($cmd . ' > /dev/null 2>&1 & echo $!');
}
 
 需要注意的事项：必须正确转义您的命令。 这些实现都没有对正在执行的命令执行任何验证，它们只是盲目地运行它。 切勿将用户输入传递给外部程序，而不必将其转移到主机操作系统！ 

It looks like you are:
 
 
 
on Windows
 
 
trying to launch an external program asynchronously
 
 
Here is the secret sauce that will allow you to do so:
 
function async_exec_win($cmd)
{
    $wshShell = new COM('WScript.Shell');
    $wshShell->Run($cmd, 0, false); // NB: the second argument is meaningless
                                    // It just has to be an int <= 10
}
 
This requires the COM class to be available to your PHP instance, you may need to enable extension=php_com_dotnet.dll in php.ini (since PHP 5.3.15/5.4.5) in order to make it available.
 
Also note that this will require a full file name of the file you wish to execute, as the extension search list will not be used outside cmd.exe. So instead of srcds -console ... you'll want srcds.exe -console ... - personally I don't like the chdir() approach, I'd rather pass the full path of the exe into the function instead - but if you do this, you'll need to make sure the directory separators are of the correct type for the operating system. PHP will let you use whatever you like wherever you like, the OS won't be so forgiving.
 
For completeness, here's how to do a similar thing on *nix. This is actually better than the Windows version as it also returns the PID of the process that was created:
 
function async_exec_unix($cmd)
{
    return (int) exec($cmd . ' > /dev/null 2>&1 & echo $!');
}
 
Something to pay attention to: your command must be properly escaped. Neither of these implementations perform any validation on the command being executed, they just run it blindly. Never pass user input to an external program without escaping it as appropriate to the host operating system!
