We are using SVN Tortoise to maintain source code. If one file is modified by one user (user A) and checked-in, another user (user B) may be working on the file at the same time. While user B check-in the same file it does not show any conflict and able to check-in. This causes the user A made changes are gone away. How to resolve this problem?<br />
<br />
&nbsp;Any help is much appreciated. Thanks.

SVN Tortoise - Concurrent check-in

Software is any set of instructions that directs a computer to perform specific tasks or operations. Computer software consists of programs, libraries and related non-executable data (such as documentation). Computer software is non-tangible, contrasted with computer hardware, which is the physical component of computers. Software written in a machine language is known as "machine code". However, in practice, software is usually written in high-level programming languages than machine language. High-level languages are translated into machine language using a compiler or interpreter or a combination of the two.

Software

Version control, also known as revision control or source control, is the management of changes to documents, computer programs, large web sites, and other collections of information. Changes are usually identified by a number or letter code, termed the "revision number," "revision level," or simply "revision." Version control systems (VCS) most commonly run as stand-alone applications, but revision control is also embedded in various types of software such as word processors and spreadsheets, and in various content management systems. Revision control allows for the ability to revert a document to a previous revision. Git, a widely-used VCS, has its own topic; other popular systems include CVS, Subversion, Team Foundation Server (TFS), Visual SourceSafe (VSS) and Perforce.

Version Control

Development in most programming languages is done with an editor or integrated development environment (IDE). Dev Tools covers issues with the use of that software, rather than the actual programming being written. XCode, Visual Studio and Eclipse are some of the more popular development tools.
