Category: Classes Group: v3.1 >Status: Pending >Resolution: Fixed Priority: 9 Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: Empty string not accepted as argument to OLE method Initial Comment: When an empty string is given as an argument to an OLE method, the method fails with error message Error 92.903: Cannot convert REXX object to VARIANT: The conversion of into a VARIANT failed. The errant behavior is exhibited by one of the ooRexx sample programs: samples\ole\apps\samp05.rex. E.g. with ooRexx 3.1 on my Windows XP SP2 system: C:\progs\ooRexx\samples\ole\apps>samp05.rex 53 *-* WordProApp~NewDocument("AutomatedDocument.lwp","","default.mwp") Error 92 running C:\progs\ooRexx\samples\ole\apps\samp05.rex line 53: OLE error Error 92.903: Cannot convert REXX object to VARIANT: The conversion of into a VARIANT failed.

I'll try to get your patches integrated today. For future reference, you don't need to open a new patch tracker item to submit patches for bugs. Just attach the patch to the original bug report. This makes the book keeping a little simpler.

So, I should be able to come up with a fix in a day or two. Or, if I don't have time during the work week, then this weekend. ---------------------------------------------------------------------- Comment By: Rony G. Flatscher (orexx) Date: 2006-08-28 15:57 Message: Logged In: YES user_id=662126 O.K., I give in, some gremlins typing the name of the wrong button: it should be the "unhide" button that assigns the empty string to the display-attribute in the style element. Sorry for this noise level... ---rony ---------------------------------------------------------------------- Comment By: Rony G. Flatscher (orexx) Date: 2006-08-28 15:09 Message: Logged In: YES user_id=662126 Oops, mixed up the buttons on the DHTML example. One needs to press the "Hide" button, which will set the value of the style attribute "display" to the empty string. ---rony ---------------------------------------------------------------------- Comment By: Rony G. Flatscher (orexx) Date: 2006-08-28 14:46 Message: Logged In: YES user_id=662126 The same behaviour can be seen with the DHTML program for MS Internet Explorer, which gets uploaded with this comment. Merely press the "Hide" button when MSIE displays the HTML text. Please note that it makes a difference whether one uses "" or " " (a single blank). In the case of MSIE the app abends in the case that a single blank is supplied in the DHTML example. As this bug can be really nasty with WSH/OLE ooRexx applications (the same program may run and then bomb, if an empty string is used), I temporarily increased the severity level to the highest value and aks Rick et.al. to adjust the level accordingly. ---rony ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=684730&aid=1547980&group_id=119701 |
