带有driectx的触摸屏设备

问题描述

我正在使用directx 9.0c托管，我想访问我的触摸屏设备。

I'm working with directx 9.0c managed, and i would like to acces to my touchscreen device.

要初始化此设备，我会这样做

To initialize this device i do that

   
 private static Microsoft.DirectX.DirectInput.Device touchscreenDevice;

public static void TouchscreenDeviceInit（Control _controlRender）
{
Microsoft.DirectX.DirectInput.CooperativeLevelFlags coopFlags;
coopFlags = Microsoft.DirectX.DirectInput.CooperativeLevelFlags.Exclusive;
coopFlags | = Microsoft.DirectX.DirectInput.CooperativeLevelFlags.Foreground;
TouchscreenDeviceInit（_controlRender，coopFlags）;
}


public static void TouchscreenDeviceInit（Control _controlRender，Microsoft.DirectX.DirectInput.CooperativeLevelFlags _coopFlags）
{
DeviceList gameControllerList = Microsoft.DirectX。 DirectInput.Manager.GetDevices（Microsoft.DirectX.DirectInput.DeviceType.ScreenPointer，EnumDevicesFlags.AllDevices）;
if（gameControllerList.Count> 0）
{
//移动到第一个设备
gameControllerList.MoveNext（）;
DeviceInstance deviceInstance =（DeviceInstance）gameControllerList.Current;

////从这个控制器创建一个设备。
touchscreenDevice = new Microsoft.DirectX.DirectInput.Device（deviceInstance.InstanceGuid）;
touchscreenDevice.SetCooperativeLevel（_controlRender，CooperativeLevelFlags.Background | CooperativeLevelFlags.NonExclusive）;
}
}

public static void TouchscreenDeviceInit(Control _controlRender) { Microsoft.DirectX.DirectInput.CooperativeLevelFlags coopFlags; coopFlags = Microsoft.DirectX.DirectInput.CooperativeLevelFlags.Exclusive; coopFlags |= Microsoft.DirectX.DirectInput.CooperativeLevelFlags.Foreground; TouchscreenDeviceInit(_controlRender, coopFlags); } public static void TouchscreenDeviceInit(Control _controlRender, Microsoft.DirectX.DirectInput.CooperativeLevelFlags _coopFlags) { DeviceList gameControllerList = Microsoft.DirectX.DirectInput.Manager.GetDevices(Microsoft.DirectX.DirectInput.DeviceType.ScreenPointer, EnumDevicesFlags.AllDevices); if (gameControllerList.Count > 0) { // Move to the first device gameControllerList.MoveNext(); DeviceInstance deviceInstance = (DeviceInstance)gameControllerList.Current; //// create a device from this controller. touchscreenDevice = new Microsoft.DirectX.DirectInput.Device(deviceInstance.InstanceGuid); touchscreenDevice.SetCooperativeLevel(_controlRender, CooperativeLevelFlags.Background | CooperativeLevelFlags.NonExclusive); } }

设备似乎已正确创建。

我打开设备

touchscreenDevice.Acquire(); //Active the device

现在，我想获取此设备的值，我不知道该怎么做。

Now, i want to get the values of this device and i don't know how to do that.

请帮助我。
