嵌入式Unity3D在WPF應用程序 - > SetWindowLong函數問題

Question

我在WPF該主機的Unity應用深化發展的應用程序。 該主機是通過使用HwndHost類（因爲與_hwndparent參數的統一方式似乎別（T工作）。

在我HwndHost類的BuilWindowCore，我需要改變使用GetWindowLong和SetWindowLong函數窗口子樣式設置。

所有這些作品完美我的深化發展的計算機上，但我不能在另一臺計算機上使用的應用。

當我剛剛設置WS_CCHILD值（不使用檢索的GetWindowLong風格）療法是不會崩潰在所有的計算機上，但子應用程序沒有正確顯示（最大化等）。這就是爲什麼我認爲問題是關於造型子窗口部分。

還有就是我HwndHost類代碼：

    private Process _process; 
    private HandleRef _hwnd; 
    private IntPtr _unityHWND; // = IntPtr.Zero;

當然，我一直試圖建立與不同的參數，與我父應用同樣的事情的統一應用。

OK

看來，問題就來了，從我的統一獨立這是不是我的消息來源，我的debug文件夾之間的相同。
