In programming, we often encounter the problem of "saving files to a database," which is no longer a difficult problem, but may be a little difficult for some of the friends who just started programming. In fact, the method is very simple, but probably because these friends just started programming soon, temporarily did not find a way. Here's a brief introduction to using C # to accomplish this task. Firs

In fact, the method is very simple, but it may be because these friends have not found a method at the moment since they just started programming.The following describes how to use C # to complete this task.First, we will introduce how to save files to the database.Save the file to the database. In fact, after converting the file into a binary stream, save the binary stream to the corresponding fields of th

Making your c ++ code robust Introduction In actual projects, when the amount of code in the project increases, you will find it increasingly difficult to manage and track its components. If it is not good, it is easy to introduce bugs. Therefore, we should master some methods that make our programs more robust. This article provides some suggestions to guide

You must use C # To dynamically create an Access database. Office 2007 is used, and the database file format is. accdb At the beginning, I thought I would check whether the file exists. If it does not exist, I would just create a database file. The Code is as follows: Strin
