Before you can make changes to source files, you must check out (make a copy on your local hard disk) the project or "module" files you want. A module is a subset of the entire project file repository.
Log in to the project's CVS server and provide your password. Then select Checkout module... from the Create menu to retrieve the latest versions of files. You will need to define the module you wish to check out and the directory where you want the checked out files to reside on you local drive.
You should always update your working copy of the project repository before you commit your changes. This ensures that you are making changes to the most recent versions of files. Updating will not overwrite your modifications if another developer has made changes to the same file(s). Instead, WinCvs attempts to merge the two versions.
To update, select the file(s) or folder(s) you wish to update and select Update files... on the Modify menu.
For information on file statuses and comparing files, see Managing files in WinCvs.
WinCvs is not a file editor. You can use the file editor of choice on your local machine to modify project files you have checked out. When you have completed your changes to files on your hard drive, you can commit those changes back into the project's CVS repository.
Whenever you create a new file on your hard disk and you want to add that file to the project, an "unknown file" icon will appear next to your new files.
Select the new file and click the "Add Selected" or "Add Selected Binary" button in the toolbar to mark the file as under version control.
Note: Adding the file does not put it into the project's CVS repository. You must then commit it.
Files that still need to be committed display a red icon next to them. To commit these files:
The results of the committing a file are displayed in the lower pane. If problems or conflicts are encountered during the merge, WinCvs aborts the commit process. You must then open the file in your file editor, resolve the conflicts, save it again, and then commit.
