Machine Vision Camera SDK (DotNet) Developer Guide
Return Value
Return MyCamera.MV_OK (0) on success; return Error Code on failure.
Remarks
You can call this API to set the value of camera node with integer type after connecting the device.
All the node values of "IInteger" 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
{
class Program
{
static void Main(string[] args)
{
uint nTLayerType = MyCamera.MV_GIGE_DEVICE | MyCamera.MV_USB_DEVICE;
MyCamera.MV_CC_DEVICE_INFO_LIST stDevList = new MyCamera.MV_CC_DEVICE_INFO_LIST();
int nRet = MyCamera.MV_CC_EnumDevices_NET(nTLayerType, ref stDevList);
if (MyCamera.MV_OK != nRet)
{
Console.WriteLine("Enum device failed:{0:x8}", nRet);
return;
}
Console.WriteLine("The number of devices found: " + Convert.ToString(stDevList.nDeviceNum));
if (0 == stDevList.nDeviceNum)
{
return;
}
MyCamera.MV_CC_DEVICE_INFO stDevInfo;
//Change the device information structure pointer to device information structure
stDevInfo = (MyCamera.MV_CC_DEVICE_INFO)Marshal.PtrToStructure(stDevList.pDeviceInfo[0],
typeof(MyCamera.MV_CC_DEVICE_INFO));
MyCamera device = new MyCamera();
//Create device

return;
}
//Open device
