捕获双网络摄像头平板电脑上的图像 [英] Capturing images on dual webcam tablets

问题描述

我已经构建了一个应用程序，可以捕获并将从平板电脑摄像头拍摄的图像上传到数据库，该应用程序适用于只有一个网络摄像头的平板电脑，但拒绝从具有双网络摄像头的平板电脑加载驱动程序。我正在使用的代码直接来自另一个代码项目解决方案， [ WhatplusisplususingplusWinFormCharpWebCam-b ]


有人知道是否有针对运动双网络摄像头的平板电脑的修复程序？



感谢一堆

解决方案

使用Silverlight 4并使用

 使用（ var  connection =  new  ComToolkit.Data.AdoConnection（connectionString））
 {
 connection.Open（）; 
  var  command = connection.CreateCommand（）; 
 command.CommandText =   SELECT MyColumn FROM MyTable; 
  var  reader = command.ExecuteReader（）; 
  while （reader.Read（））
 {
  object  byindex = reader [ 0 ]; 
  object  bystring = reader [  MyColumn ]; 
  //  要使用动态属性，必须将阅读器声明为动态。 
 < span class =code-comment> //   object bydynamic = reader.MyColumn;  
} 
} 

I have built an application that will capture and upload images taken from a tablet webcam to a database, the app works on tablets that only have one webcam but refuses to load the driver from tablets that have dual webcams. The code I'm using is straight from another code project solution, [WhatplusisplususingplusWinFormCharpWebCam-b]

Does anybody know if there is a fix for tablets sporting dual webcams?

Thanks a bunch

解决方案

use Silverlight 4 and attach the database using

using (var connection = new ComToolkit.Data.AdoConnection(connectionString))
{
    connection.Open();
    var command = connection.CreateCommand();
    command.CommandText = "SELECT MyColumn FROM MyTable";
    var reader = command.ExecuteReader();
    while (reader.Read())
    {
        object byindex = reader[0];
        object bystring = reader["MyColumn"];
        //to use dynamic properties reader must be declared as dynamic.
        //object bydynamic = reader.MyColumn;
    }
 }
