问题 I have a gridview with a data template which includes a togglebutton. The datatemplate for the items in the Gridview has a grid in it, with a stylized togglebutton. The style for the togglebutton is located in Grid.Resources.

问题 I am developing an app that put text into a background image. The textblocks are placed on a canvas control as children and I render the canvas to PNG. Then I use the BlendEffect to blend it with a background image. UPDATE This post is specifically about chaining effects with Lumia Imaging SDK. Unfortunately one of the person who commented was having a tunnel vision and insist that I must learn about the difference between lossy and lossless image.

问题 I have a c++ dll that I want to utilize in the UWP project that I am working on. I need some assistant on how to achieve that. 回答1: C++ doesn't have a concept of "referencing DLLs".
