Cognitive Digital pixel resolution: First from the resolution (digital pixel) perspective, from the SD ERA to HD, from 720x576 to the present 1920x1080, aspect ratio from 4:3 to 16:9, this is familiar to us, 4K is actually built on the basis of high-definition, We call it the "Ultra HD" UltraHD, from the 720x576 400,000 megapixel to the 20 million pixels of HD 1920x1080. By 4K, our resolution has risen 4 times times on a high-definition basis, from 1920x1080 (1080p60) to 3840x2160 (2160P60), wh

Introduction to the SDI encoder (E500)SDI encoder (E500) is a high-performance SDI coding product produced by Shanghai Visual Technology. The SDI encoder is a fully independent research and development of Shanghai Vision Electronics, and is suitable for the coding acquisition and network transmission of all kinds of

In the previous four, I introduced the use of the Tangrammini component in the dialog box program, and I will briefly introduce the use of the Tangrammini component in the SDI (Single Document Interface) program. Using Tangrammini components to build frameworks in SDI programs makes application framework design faster and simpler. Nonsense I don't say much, directly into the subject. Note that to install t

What is the difference between SDI signal and ASI signal? Can we convert each other?, let the long come to tell you. For decades, the rapid development of computer technology, rapid, the emergence of operating systems and word processing functions have become a major technological revolution in computer history two times. Now, the third wave of computer revolution--pctowards"pc3+ E"--is sweeping through. pc3+ EIt meansPCfrom a simple PC to personal co

How to Implement the conversion between SDI and MDI? If you want to write a compiled SDI application Program To convert to MDI, you must first create a class that inherits cmdichidwnd. Assume It is cchldfrm and make the following changes in cwinapp. Initinstance () { .... // Instead of adding csingledoctemplate // Add cmultidoctemplate. Pdoctemplate = new cmultidoctemplate ( Idr_mainframe, Runtime_class (

call cdoctemplate: opendocumentfile (null ).Cdoctemplate: opendocumentfile (lpctstr lpszpathname, bool bmake_visible = true) has different processing methods for SDI and MDI.For SDI,(1) If a document is opened and reinitialized, call cdocument: savemodified () to save the current document. If noIf a document exists, call createnewdocument () to create the document object, and then call createnewframe (pdou

In a single document view (SDI) structure, a view is generally used to display data. However, you sometimes want to display buttons or other controls in the view to meet your needs. Vc6.0 does not directly provide a wizard for adding buttons to the view (maybe yes, I did not find it ). Next, I will provide a function to manually add buttons and make them respond to events. Step 1: Add a button First, define a button identifier in ** view. h. # Define

Problem: One MFC-SDIProgramWhen it is disabled, the system automatically prompts "whether to save the changes to XXX", but does not want such a prompt. At the same time, it is found that after opening a document and then opening a document, such a prompt will also appear. Solution Process: 1. Insert a breakpoint in void cmainframe: onclose (). The prompt dialog box is generated by cframewndex: onclose. 2. Track the implementation of the cframewndex: onclose () function and find that t

Today, we have finally finished the interface that we have always wanted to do like MMC in windows. Now I have a little fun, and I will summarize my experiences as follows: 1. Create an SDI project named dbvview in vc6.0, and select "application split form" in the Windows style in Step 6 of the wizard ". After the project is created, we can see that the project created by the "Application split form" option is selected is different from the genera

SDI is short for single-document interface applications. In this article, you need to display an image in the view area, display text on the image surface, and move the text following the mouse. Think about it and you can judge that this problem is divided into the following parts: 1. display images; 2. Locate the mouse position; 3. Insert text; 4. automatically move text. Perform the following steps. 1. First, open an image and display it in "open" m

This paper mainly describes how to achieve the single document SDI and OpenGL Multi-view Segmentation window under VC + + environment, the final interface is similar to the 3DMAX main interface. First give me what I realized:The entire implementation process there are a lot of scattered blog posts on the network, please do your own search, in a dialog-based, single document or multi-document implementation of multi-view split window principle is consi

Search on the Internet a lot of information, found to be able to display the button on a single document, but is unable to respond to events, For a long time, found M_pbutton->create () to be placed in the C***view class of OnCreate (). But in VS2008 new single document program C***view class does not overload the OnCreate () function, to Overload the function yourself, which can be generated using the wizard. Here is a detailed procedure: A new SDI
