FOXTOOLS is a FoxPro library that exposes Macintosh system functions for use in FoxPro for Macintosh. Functions in the FOXTOOLS library allow you to set and retrieve file information, manipulate paths and filenames, use Macintosh system alerts, and perform many other functions.

When you install FoxPro for Macintosh, FOXTOOLS.MLB is installed in the System Folder:Extensions folder. To use the FOXTOOLS functions, use the command SET LIBRARY TO FOXTOOLS. 

                        FOXTOOLS Functions

AddBS( )

Syntax: AddBS(<expC>)

The AddBS( ) function returns the path specified by the parameter <expC>, with a trailing colon. The function doesn't add the trailing colon if <expC> already has one or is a null string.

<expC> 

   Specifies the path.
CleanPath( )

Syntax: CleanPath(<expC>)

On the Macintosh, the function CleanPath( ) returns the string passed to it. This function is included for cross-platform compatibility with FoxPro for Windows.

<expC> 

   Specifies the path:filename.
DefaultExt( )

Syntax: DefaultExt(<expC1>, <expC2>)

If <expC1> does not contain an extension, the DefaultExt( ) function returns the parameter <expC1> with the extension specified by <expC2> added to the path:filename. If <expC1> contains an extension, then <expC1> is returned unchanged.

<expC1> 

   Specifies the path:filename to be returned.
<expC2> 
   Specifies the default extension.
ForceExt( )

Syntax: ForceExt(<expC1>, <expC2>)

The ForceExt( ) function returns <expC1> with the extension changed to the extension specified by the parameter <expC2>. If <expC1> does not have an extension, the new extension is added.

<expC1> 

   Specifies the path:filename that will get a new extension.
<expC2> 
   Specifies the new extension for <expC1>.
ForcePath( )

Syntax: ForcePath(<expC1>, <expC2>)

The ForcePath( ) function returns the parameter <expC1> with the path portion changed to the path specified by the parameter <expC2>.

<expC1> 

   Specifies the path:filename that will get a new path.
<expC2> 
   Specifies the new path for <expC1>.
FxAlert( )

Syntax: FxAlert(<expN1>, <expN2>, <expN3>, <expN4>[, <expC1>] [, <expC2>][, <expC3>][, <expC4>])

The FxAlert( ) function displays an alert and waits for a user response. One of three icons will be displayed on the alert, based on the type of alert that you specify in <expN1>. FxAlert( ) returns a value representing the user exit action.

<expN1> 

   Specifies a number that indicates the icon to be displayed on the
alert. 0=CAUTION; 1=STOP; 2=NOTE.

<expN2> 

   Specifies the resource number. FOXTOOLS contains the same twelve
alerts provided in the FOXUSER file of FoxBASE+ for Macintosh. In FOXTOOLS, the resource numbers are 257 through 268 instead of 1 through 12 as in FoxBASE+ for Macintosh. An alert contains different possible push button combinations that you can choose. For example, resource number 259 contains the push buttons "Yes" and "No" with the focus initially on the "Yes" push button.

<expN3>, <expN4> 

   Specify the coordinates, measured in pixels from the top left of
the screen, at which the alert will be placed. Use a value of -1 for <expN3> and/or <expN4> to accept the default position. The default position is centered.

[, <expC1>][, <expC2>][, <expC3>][, <expC4>] 

   Specify text that will appear on the alert.
The following table shows the push buttons displayed on each of the twelve alerts with the default focus push button shown in parentheses. 

Res#   Button 1     Button 2    Button 3   Note
257 (Continue) 258 (OK) 
259    (Yes)         No

264    (OK)                                Bigger alert than 258
265    (Yes)         No                    Bigger alert than 259
266     Yes         (No)                   Bigger alert than 260
267    (Yes)         No         Cancel     Bigger alert than 261
268     Yes         (No)        Cancel     Bigger alert than 262
FxFileType( )

Syntax: FxFileType(<expC1>, @<expC2>, @<expC3>)

The FxFileType( ) function stores the type of a file to the variable <expC2> and stores the creator of the file to the variable <expC3>. FxFileType( ) returns 0 for no error or returns a Macintosh Operating System error number.

<expC1> 

   Specifies the path:filename for which you want to obtain the file
type and file creator. The path:filename should be a Macintosh path:filename. If you want to use MS-DOS conventions for paths and filenames, you need to convert the path and filename for Macintosh use by using SYS(2027,"<path><filename>"). 
   Example: SYS(2027,"MacHD:\FoxPro\FoxTools") will return
"MacHD:FoxPro:FoxTools"

@<expC2> 

   Specifies the pre-created variable, passed by reference, to which
the function will store the file type.

@<expC3> 

   Specifies the pre-created variable, passed by reference, to which
the function will store the file creator.

FxGDepth( )

Syntax: FxGDepth( )

The FxGDepth( ) function returns the number of colors available with the current graphics device.

FxGVolume( )

Syntax: FxGVolume( )

The FxGVolume( ) function returns a list of volume names created by the SET VOLUME command. For example, the following will return "E MacHD:\FoxPro" and any other volume names created by SET VOLUME:

SET VOLUME e TO "MacHD:FoxPro" ?FxGVolume( )

FxKeyboard( )

Syntax: FxKeyboard( )

The FxKeyboard( ) function returns an integer value that indicates the type of keyboard that is currently attached to the system. If the Apple Desktop Bus (ADB) is being used and multiple keyboards are attached, the value returned indicates which keyboard registered the last keystroke. 

      0 =  unable to determine
      1 =  MacKbd
      2 =  MacAndPad
      3 =  MacPlusKbd

file type. Since the file type is four bytes long, <expC2> should be four characters. Strings longer than four characters are truncated. Strings shorter than four characters are padded with '0'.

<expC3> 

   Specifies the pre-created variable that contains a value to set the
file creator. Since the file creator is four bytes long, <expC3> should be four characters. Strings longer than four characters are truncated. Strings shorter than four characters are padded with '0'.

FxStripLF( )

Syntax: FxStripLF(<expC>)

The FxStripLF( ) function opens a file specified by the parameter <expC>, removes all the line feed characters (CHR(10)), and saves the file using its original path:filename. FxStripLF( ) always returns .T., but generates a standard "File Read Error" (#1104) if it cannot read or find the file passed to it by <expC>, or generates a "File Write Error" (#1105) if it cannot save the file.

Reduce( )

Syntax: Reduce(<expC1>[, <expC2>[, <expN>]])

The Reduce( ) function reduces multiple white space characters to a single space and trims all leading and trailing white space. If the optional parameter <expN> is non-zero, strings in quotation marks will be unaffected. <expN> can only be used with the optional parameter <expC2>, which specifies the string of word delimiters. Reduce( ) returns the modified string.

<expC1> 

   Specifies the string to be reduced.
[, <expC2>[, <expN>]] 
   <expC2> specifies the string of word delimiters. If <expC2> is not

On the Macintosh, the ValidPath( ) function always returns .T. regardless of the path passed to it. This function is included in FoxTools for cross-platform compatibility with FoxPro for Windows.

<expC> 

   Specifies the path:filename.
WordNum( )

Syntax: WordNum(<expC1>, <expN>[, <expC2>])

The WordNum( ) function returns the specified word in the string <expC1>. The words are delimited by the optional parameter <expC2>. If <expC2> is not included, WordNum( ) assumes that words are delimited by spaces and tabs.

<expC1> 

   Specifies the string of words.
<expN> 
   Specifies the numeric position of the word to be returned. <expN> =
3 would return the third word in <expC1> or a null string if <expC1> contains fewer than three words.

[, <expC2>] 

   Specifies the string of word delimiters. If <expC2> is not used,
then the default delimiters are assumed to be spaces and tabs.

Words( )

Syntax: Words(<expC1>[, <expC2>])
