[英]System.Windows.Markup.XamlParseException For Kinect
我目前面臨着離散手勢基礎-WPF的Microsoft Kinect SDK 2.0瀏覽器示例代碼的怪異問題
目標:是將我自己的手勢記錄在filename.gbd中添加到數據庫中,並能夠在其中提取手勢。
問題:當我將初始名稱從“ Seated.gbd”更改為“ RightHandHandsUp.gbd”時,發生以下錯誤。
但是,如果我將“ RightHandHandsUp.gbd”文件重命名為“ Seated.gbd”(默認設置),它將可以正常工作。 這很奇怪,但是我懷疑程序中的某處有一些綁定,但是我已經嘗試在整個項目中搜索關鍵字。
提前致謝!!
System.Windows.Markup.XamlParseException: ''The invocation of the constructor on type 'Microsoft.Samples.Kinect.DiscreteGestureBasics.MainWindow' that matches the specified binding constraints threw an exception.' Line number '4' and line position '9'.'
有2個內部例外:
InvalidOperationException: This API has returned an exception from an HRESULT: 0x80004005
和
COMException: Error HRESULT E_FAIL has been returned from a call to a COM component.
所以在GestureDetector.cs文件中,我更改了文件名。

就我而言,我不知道DiscreteGestureBasics正在使用AdaBoostTech.dll和RFRProgressTech.dll。 我將DiscreteGestureBuilder示例bin目錄中的目錄vgtech復制到了其他項目bin目錄中,一切正常。
