{ Free Vision Runtime Library }
{ StdDlg Unit }
{ Version: 0.1.0 }
{ Release Date: July 23, 1998 }
{ }
{*******************************************************}
{ }
{ This unit is a port of Borland International's }
{ StdDlg.pas unit. It is for distribution with the }
{ Free Pascal (FPK) Compiler as part of the 32-bit }
{ Free Vision library. The unit is still fully }
{ functional under BP7 by using the tp compiler }
{ directive when rebuilding the library. }
{ }
{*******************************************************}
{ Revision History
1.1a (97/12/29)
- fixed bug in TFileDialog.HandleEvent that prevented the user from being
able to have an action taken automatically when the FileList was
selected and kbEnter pressed
1.1
- modified OpenNewFile to take a history list ID
- implemented OpenNewFile
1.0 (1992)
- original implementation }
unit StdDlg;
{
This unit has been modified to make some functions global, apply patches
from version 3.1 of the TVBUGS list, added TEditChDirDialog, and added
several new global functions and procedures.

{ Functions of type FileConfirmFunc's are used to prompt the end user for
confirmation of an operation.
FileConfirmFunc's should ask the user whether to perform the desired
action on the file named AFile. If the user elects to perform the
function FileConfirmFunc's return True, otherwise they return False.
Using FileConfirmFunc's allows routines to be coded independant of the
user interface implemented. OWL and TurboVision are supported through
conditional defines. If you do not use either user interface you must
compile this unit with the conditional define cdNoMessages and set all
FileConfirmFunc variables to a valid function prior to calling any
routines in this unit. }
{#X ReplaceFile DeleteFile }

otherwise it returns False.

function Contains(S1, S2: String): Boolean;
{ Contains returns true if S1 contains any characters in S2. }

{ DriveValid returns True if Drive is a valid DOS drive. Drive valid works
by attempting to change the current directory to Drive, then restoring
the original directory. }
function ExtractDir(AFile: FNameStr): DirStr;
{ ExtractDir returns the path of AFile terminated with a trailing '\'. If
AFile contains no directory information, an empty string is returned. }
function ExtractFileName(AFile: FNameStr): NameStr;
{ ExtractFileName returns the file name without any directory or file
extension information. }
function Equal(const S1, S2: String; Count: Sw_word): Boolean;
{ Equal returns True if S1 equals S2 for up to Count characters. Equal is
case-insensitive. }

{ FileExists looks for the file specified in AFile. If AFile is present
FileExists returns true, otherwise FileExists returns False.
The search is performed relative to the current system directory, but
other directories may be searched by prefacing a file name with a valid
directory path.
There is no check for a vaild file name or drive. Errrors are handled
internally and not reported in DosError. Critical errors are left to
the system's critical error handler. }

ends with a trailing backslash '\'. }

operating system. }

needed for the StdDlg unit to function on the RezFile using the string
constants and variables in the Resource unit. The Resource unit and the
appropriate string lists must be initialized prior to calling this
procedure. }

and returns the result. }

{ OpenFile prompts the user to select a file using the file specifications
in AFile as the starting file and path. Wildcards are accepted. If the
user accepts a file OpenFile returns True, otherwise OpenFile returns
False.
Note: The file returned may or may not exist. }
function OpenNewFile (var AFile: FNameStr; HistoryID: Byte): Boolean;
{ OpenNewFile allows the user to select a directory from disk and enter a
new file name. If the file name entered is an existing file the user is
optionally prompted for confirmation of replacing the file based on the
value in #CheckOnReplace#. If a file name is successfully entered,
OpenNewFile returns True. }

file or directory name. Trailing '\'s are removed. }

{ RegisterStdDlg registers all objects in the StdDlg unit for stream
usage. }
function SaveAs (var AFile : FNameStr; HistoryID : Word) : Boolean;
{ SaveAs prompts the user for a file name using AFile as a template. If
AFile already exists and CheckOnReplace is True, the user is prompted
to replace the file.
If a valid file name is entered SaveAs returns True, other SaveAs returns
False. }
function SelectDir (var ADir : DirStr; HistoryID : Byte) : Boolean;
{ SelectDir prompts the user to select a directory using ADir as the
starting directory. If a directory is selected, SelectDir returns True.
The directory returned is gauranteed to exist. }
function ShrinkPath (AFile : FNameStr; MaxLen : Byte) : FNameStr;
{ ShrinkPath returns a file name with a maximu length of MaxLen.
Internal directories are removed and replaced with elipses as needed to
make the file name fit in MaxLen.
AFile must be a valid path name. }

AFile with the new AFile, otherwise it returns False.

optionally replaced based on the value of CheckOnReplace.

user. If CheckOnReplace is True, the end user is asked to replace the
file using a call to ReplaceFile.
CheckOnReplace is set to True by default. }
CheckOnDelete : Boolean = True;
{ CheckOnDelete is used by file and directory functions. If a file
exists, it is optionally deleted based on the value of CheckOnDelete.
If CheckOnDelete is False the file or directory is deleted without
asking the user. If CheckOnDelete is True, the end user is asked to
delete the file/directory using a call to DeleteFile.
