You can call this API to set specified float node after connecting the device. All the node values of
"IFloat" in the list can be set via this API. strKey corresponds to the Name column.
Example
C#
using System;
using System.Runtime.InteropServices;
using System.IO;
using MvCamCtrl.NET;
namespace Param

if (MyCamera.MV_OK != nRet)
{

return;
}
Console.WriteLine("The number of devices found: " + Convert.ToString(stDevList.nDeviceNum));

}
