The WPF form and all internal elements are measured by device-independent units. A device irrelevant unit is defined as one of 96 points of 1 inch, that is, 1/96 inch.
Suppose we have created a WPF button in 96X96 units. If standard Windows DPI settings (96 dpi) are used ), the size of each unit is a physical pixel in the real world. The calculation formula is as follows:
Physical unit size = device indep

Many designers and engineers were confused by the various screens of Android devices. I did both the UI design and the android interface layout. I was just familiar with this content, I have also made related lectures within the company. Here, I will reorganize this part of knowledge and share it with you!

Use Metaspoit to attack ms08-067The ms08-067 vulnerability is all known as the Windows Server service RPC request buffer Overflow vulnerability, which could allow remote code execution if a user receives a specially crafted RPC request on an affected system.On Microsoft Windows 2000Windows XP and Windows Server 2003 systems, an attacker may be able to run arbitrary code with this vulnerability without authentication, a vulnerability that could be used for a worm attack, and there is already a wo
In the Android program, the icons are set in the drawable, but the results are not shown in Millet 2, but they appear normal in my own HTC and emulator. It was later found that the DPI of millet was not the same.
It was later discovered that Android loaded a series of icons to accommodate different resolutions and DPI.

Questions about viewport
Viewport is not only unique in ios, but also has viewport on android and winphone. They solve the same problem, that is, directly resetting the resolution between the physical size and the browser through dpi, regardless of the actual resolution of the device. This resolution is irrelevant to the resolution of the device. For example,
GDI windows form application uses the operating system control to establish its application. Therefore, it is basically difficult to customize them in your application. The WPF control is actually drawn on your screen. Therefore, if necessary, you can completely customize the control and modify its behavior.Features of WPF
WPF has many advantages. Let me introduce the following:Pixels unrelated to devices (DPI)
WPF introduces device-independent
To handle a wide range of resolutions and sizes.
For images, Android uses DPI as the unit. If you select an image, right-click the image under win and you will see the DPI attribute. The higher the DPI, the finer the image. For a mobile phone or display device, a pixel is a point, so DPI = PPI. In turn, it is often sai
