File

This object is the building block for projects. Every project contains a Files collection composed of File objects. Each File object represents one file (or group of files, like a form) in the project.

Property	Value	Purpose
CodePage	Numeric	The codepage for this file.
Description	Character	The description saved for this file. The description appears in the bottom panel of the Project Manager when the file has focus.
Exclude	Logical	Indicates whether the file is to be included in an APP or EXE built from the project. Actually, indicates whether it should be excluded.
FileClass, FileClassLibrary	Character	If the file is a form, these two indicate the name and library of the class it's based on. If the file is not a form, each contains an empty string.
LastModified	DateTime	The date and time at which the file was last changed.
Name	Character	The filename, including the path.
ReadOnly	Logical	This property tells you if the file can be edited. ReadOnly is .T. if the file is checked in under source code control or if it is flagged Read-Only. ReadOnly cannot be directly changed—you need to either check out the file or clear the Read-Only attribute to toggle this property.
SCCStatus	Numeric	Indicates the file's status with the project's source control provider. If there is no source control provider, contains 0.
Type	Single character	Indicates what kind of file this is.

Method	Purpose
AddToSCC	Adds the file to the project's source control provider.
CheckIn	Checks the file into the source control provider.
CheckOut	Checks the file out of the source control provider.
GetLatestVersion	Brings a read-only copy of the file in its current state to the local drive.
Modify	Opens the file in its native editing tool.
Remove	Removes the file from the project, optionally deleting it from the disk as well.
RemoveFromSCC	Removes the file from source control.
Run	Runs the file. For reports, previews the file.
UndoCheckOut	Changes the file's source control status to checked in, discarding any changes since checkout.

It might seem that there's a method missing from the list—Add. But you can't apply Add to a file object because there is no such object at the time you're adding the file. So Add is a Files collection method.

File, like Project, is a COM class, not a native VFP class. This means, among other things, that it has no events. It also means we can't subclass it, because we have no control over the creation of File objects. It happens automatically when a project is opened or when a file is added to a project.

Example

* See what's in a project FOR EACH oFile IN _VFP.ActiveProject.Files    ? oFile.Name, oFile.Type ENDFOR
