What is WPTOOLS.DLL:
WPTOOLS.DLL is a Dynamic Link Library that contains code to query the
settings for workplace shell objects. This DLL is used by WPSBKP.EXE but
can also be used from within a REXX program.
The following REXX functions are available:
Function: WPToolsLoadFuncs
Purpose : Make the functions in WPTOOLS.DLL available to REXX.
Usage:
/* First declare WPToolsLoadFuncs itself to REXX */
call RxFuncAdd 'WPToolsLoadFuncs', 'WPTOOLS', 'WPToolsLoadFuncs'
/* Call WPToolsLoadFuncs itself. */
call WPToolsLoadFuncs
Function: WPToolsQueryObject
Purpose : Query objects
Usage : rc=WPToolsQueryObject(object, [Class], [Title], [Setup], [Location])
Where:
object = A fully qualified path name to a file or directory, or
An OBJECTID string (e.g. <WP_DESKTOP>), or
A string starting with a '#' and being followed
by a hexadecimal object handle (See WPToolsFolderContent)
Class = The name of a REXX variable, enclosed in quotes,
that will be created by WPTOOLS and will contain the
class name of the object. This argument is optional.
Title = The name of a REXX variable, enclosed in quotes,
that will be created by WPTOOLS and will contain the
title of the object. This argument is optional.
Setup = The name of a REXX variable, enclosed in quotes,
that will be created by WPTOOLS and will contain the
setup string of the object. This argument is optional.
Location = The name of a REXX variable, enclosed in quotes,
that will be created by WPTOOLS and will contain the
location of the object. This argument is optional.
Returns: 1 on success and 0 when a error occurred.
Please note that only the object argument is mandatory. All other arguments
only need to be present when the result is needed. Should you not need one
argument, but need a argument that is after the not needed one, make sure
you enter all comma's. (e.g.: rc = WPToolsQueryObject(object,,,"SetupString")
See Appendix I and II for information about objects and the setup values
this call returns.
Example:
/* REXX must start with a comment line */
call RxFuncAdd 'WPToolsLoadFuncs', 'WPTOOLS', 'WPToolsLoadFuncs'
call WPToolsLoadFuncs
iRetco = WPToolsQueryObject("<WP_DESKTOP>", "szClass", "szTitle", "szSetupString", "szLocation")
if Iretco Then do
say 'Class name :' szclass
say 'Title :' sztitle
say 'Location :' szlocation
say 'Setupstring:' szsetupstring
end
else
say 'Unable to return object settings for <WP_DESKTOP>'
End of Example
Function: WPToolsFolderContent
Purpose : Query abstract (non-disk) objects in a specific folder
Usage : rc=WPToolsFolderContent(folder, stem [,'F'])
Where :
folder = A fully qualified path name to a directory, or
an OBJECTID string for a folder (e.g. <WP_DESKTOP>
stem = The name of a REXX stem variable that, on successful
return, will contain all abstract objects present
in a specific folder. Each returned entry will either
be an OBJECTID (when an OBJECTID has been set for
the returned object) or a string starting with a '#' and
followed by the hexadecimal object handle.
'F' = If specified, WPToolsFolderContent will return all
filesystem objects as well.
Returns: 1 on success and 0 when a error occurred.
Example:
/* REXX must start with a comment line */
call RxFuncAdd 'WPToolsLoadFuncs', 'WPTOOLS', 'WPToolsLoadFuncs'
call WPToolsLoadFuncs
iRetco = WPToolsFolderContent("<WP_DESKTOP>", "list.")
if iRetco = 0 Then Do
exit
End
say 'Abstract objects on <WP_DESKTOP>:'
do iObject = 1 to list.0
Iretco=WPToolsQueryObject(list.Iobject, "szclass", "sztitle", "szsetupstring", "szlocation")
if Iretco Then do
say '"'szClass'", "'szTitle'", "'szSetupString'", "'szLocation'"'
end
end
End of Example
Function: WPToolsSetObjectData
Purpose : Change the settings of an existing object
Usage : rc=WPToolsSetObjectData(object, setup)
Where :
object = A fully qualified path name to a file or directory, or
An OBJECTID string (e.g. <WP_DESKTOP>), or
A string starting with a '#' and being followed
by a hexadecimal object handle (See WPToolsFolderContent)
setup = A WinCreateObject setup string
Returns: 1 on success and 0 when a error occurred.
NOTE: This function is equal to SysSetObjectData with one difference that
beside a file name or OBJECTID also a '#' followed by an hexadecimal
object handle can be specified. This makes it posible that the outcome
if WPToolsFolderContant can be used.
Function: WPToolsVersion
Purpose : Query version of WPTOOLS.DLL
Usage : version=WPToolsVersion()
Example:
/* REXX must start with a comment line */
call RxFuncAdd 'WPToolsLoadFuncs', 'WPTOOLS', 'WPToolsLoadFuncs'
call WPToolsLoadFuncs
Version = WPToolsVersion()
say 'WPTOOLS.DLL is of version' version
End of Example

APPENDIX II
WPToolsQueryObject has code to support (almost) all object classes for
which object setup strings are defined, being:
Class Setup strings returned

WPObject CCVIEW, DEFAULTVIEW, HELPPANEL, HIDEBUTTON, MINWIN, NOCOPY,
NODELETE, NODRAG, NODROP, NOLINK, NOMOVE, NOPRINT, NORENAME,

TREEVIEW, DETAILSVIEW, WORKAREA,
WPLaunchPad All documented setup strings.
(1) Along with all settings for WPPrint.
(2) These settings cannot be used to recreate the object.
(3) MENU doesn't work when applying.
For each object, WPToolsQueryObject returns setup string values not only for the object
itself (when supported) but also for all parent classes. When, for example,
one uses WPToolsQueryObject against the Desktop (class WPDesktop) setup strings
will be returned from the classes WPFolder, WPFileSystem and WPObject.
I did not build any support for WPSchemePalette because the setup string
for this class do not support settings the colors on an individual basis but
instead one should specify a color scheme name that is already present
in the INI files.
HISTORY:
Version 1.00 - Initial release
Version 1.01 - Added support for the Launchpad.
Added a new REXX API call: WPToolsVersion
Version 1.02/1.19 - Not released
Version 1.20 - Increased several internal buffers to accommodate OS/2
Warp Version 4 (Merlin) GAMMA.
Version 1.21 - Changed the return code from WPToolsFolderContent for '0' to '1'
when a folder does not contain any abstract objects.
Version 1.32 - Enlarged an internal buffer to overcome a buffer too
small error for tag 12.
Version 1.33 - Added WPToolsSetObjectData as new REXX API call.
Modified WPToolsFolderContent so it will, optionally,
return all filesystem objects as well.
Version 1.34 - Corrected WPHost to return a proper password.
Version 1.35 - Added logic for the WarpCenter.
Version 1.37 - Corrected one of the internal functions for a possible
problem.
Version 2.00 - Corrected a problem because internal objecthandles with
their HIWORD being 0x0004 were not recoqnized as file system
objects.
Version 2.01 - Corrected a problem in an internal routine for retrieving data
from the ini's. These routine failed if the key didn't contain
any data.
Version 2.11 - Changed to compiler to VAC 3.0.
Version 2.12 - Did some internal changes.
