首先打开注册表编辑器，展开“HKEY_LOCAL_MacHINESystemCurrentControlSetServicesKbdclassParameters”，设置键值数据项“KeyboardDataQueueSize”的数值数据为需要的键盘缓存大小即可；“MouseDataQueueSize”的数值数据为需要的鼠标缓存大小即可。如果没有此数值，自己建立数值数据即可。如果不知道设置缓存数据多少，那...
打开注册表编辑器,然后打开HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\kbdclass\Parameters,然后修改KeyboardDataQueueSize的值,默认是100(十进制),改大点就行了,但也别改得太大了,修改注册表还是谨慎为好,我改得150(十进制)。不过以撒这游戏键盘操作是真的频繁,鬼知道缓冲区改大之后会不会还出现因溢出...
MouseDataQueueSize - Specifies the number of mouse events buffered by the mouse driver. It also is used in calculating the size of the mouse driver's internal buffer in the nonpaged memory pool. Absolute pointing devices For devices of type GUID_CLASS_MOUSE, a device's function driver: Handl...
calls the keyboard class driver's implementation ofPSERVICE_CALLBACK_ROUTINE. A vendor can implement a filter service callback to modify the input data that is transferred from the device's input buffer to the class data queue. For example, the callback can delete, transform, or insert data....

provides a template for a filter service callback routine that can supplement the operation ofKeyboardClassServiceCallback, the Kbdclass class service callback routine. The filter service callback can filter the input data that is transferred from the device input buffer to the class d...
Retrieves the window handle to the active window attached to the calling thread's message queue. GetAsyncKeyState Determines whether a key is up or down at the time the function is called, and whether the key was pressed after a previous call to GetAsyncKeyState. ...

Having discussed the two bigger design considerations for newcomers to the mechanical keyboard hobby—size/layout and staggered/ortholinear layouts, the remaining topics to cover are a bit more straightforward. Entry number three in our intro series will cover low vs high-profile keyboard designs. ...
