我正在尝试使用Synaptics SDK在Synaptics触控板上获取设备句柄,特别是使用SYNCTRLLib中的方法。
但是,SYNCTRL
方法无法找到它,返回-1
。
Syn.cs:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using SYNCOMLib;
using SYNCTRLLib;
namespace TP_Test1
{
class Syn
{
SynAPICtrl SynTP_API = new SynAPICtrl();
SynDeviceCtrl SynTP_Dev = new SynDeviceCtrl();
SynPacketCtrl SynTP_Pack = new SynPacketCtrl();
int DeviceHandle;
//Constructor
public Syn ()
{
SynTP_API.Initialize();
SynTP_API.Activate();
//DeviceHandle == -1 ? Can't find device?
DeviceHandle = SynTP_API.FindDevice(new SynConnectionType(), new SynDeviceType(), 0);
//Below line causing Unhandled Exception
SynTP_Dev.Select(DeviceHandle);
SynTP_Dev.Activate();
SynTP_Dev.OnPacket += SynTP_Dev_OnPacket;
}
public void SynTP_Dev_OnPacket()
{
Console.WriteLine(SynTP_Pack.FingerState);
Console.WriteLine(SynTP_Pack.X);
Console.WriteLine(SynTP_Pack.Y);
}
}
}
Program.cs的
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using SYNCOMLib;
using SYNCTRLLib;
namespace TP_Test1
{
class Program
{
static void Main(string[] args)
{
Syn mySyn = new Syn();
mySyn.SynTP_Dev_OnPacket();
}
}
}

我看到你正在使用Synaptics SDK的C#包装器。尽管CPP代码对您来说可能并不重要,但您可能需要查看文件 Samples / ComTest.cpp 。它包含一些示例逻辑,以便查找设备,更具体地说,在第66-76行:
// Find a device, preferentially a TouchPad or Styk.
ISynDevice *pDevice = 0;
long lHandle = -1;
if ((pAPI->FindDevice(SE_ConnectionAny, SE_DeviceTouchPad, &lHandle) &&
pAPI->FindDevice(SE_ConnectionAny, SE_DeviceStyk, &lHandle) &&
pAPI->FindDevice(SE_ConnectionAny, SE_DeviceAny, &lHandle)) ||
pAPI->CreateDevice(lHandle, &pDevice))
{
printf("Unable to find a Synaptics Device.\n");
exit(-1);
}
另外,请确保您已注册 dll 。根据 ReadSynSDK.txt 文件:
出于某些目的,可能需要注册dll 随SDK提供。这可以通过windows regsvr32来完成 效用
