C++ WPF通过HWND和HINSTANCE的C++/CLI

Question

如何传递C＃WPF表单的HWND和HINSTANCE？

尝试：

C++/CLI：

BOOL Initialize(double width, double height, HWND parent, HINSTANCE hiparent) 
{ 

C＃

HwndSource hwnd = (HwndSource)HwndSource.FromVisual(this.renderControl); 
IntPtr hinstance = Marshal.GetHINSTANCE(typeof(App).Module); 

engine.Initialize(this.Width, this.Height, hwnd, hinstance); 

但是抛出：

参数4：不能从 'System.IntPtr' 转换到'HINSTANCE __ *' 参数3：can不能转换从“System.Windows.Interop.HwndSource”到 “HWND __ *”

所以，我怎么能转换到这些的？

Answer 1

考虑尝试这样的：

engine.Initialize(this.Width, this.Height, hwnd.Handle.ToPointer(), hinstance.ToPointer()); 

IntPtr.ToPointer()返回void*这应该是转换为HWND和HINSTANCE。

Answer 2

尝试类似：

engine.Initialize(this.Width, this.Height, (HWND)(hwnd.Handle.ToPointer()), (HINSTANCE)hinstance.ToPointer());
