Frans Vermeulen | Ownerdraw, XbpListbox, W2K terminalserver on Fri, 04 Apr 2008 16:38:37 +0200 It looks like the in the subject mentioned combination: using a class derived from XbpListbox Having :Drawmode set to either: XBP_DRAW_OWNER or XBP_DRAW_OWNERADVANCED Crashes in the method :drawitem(), when executed on a W2K terminal server. See below for an errorlog. Having no method :DrawItem() using the same :Drawmode results in a similar errorlog. (Also only on W2K terminal server, not on XP nor W2K ws.) Can anyone confirm ? Does anyone know a workaround ?

How can I check, before crashing ? Regards, Frans Vermeulen | |
Frans Vermeulen | Re: Ownerdraw, XbpListbox, W2K terminalserver on Tue, 27 May 2008 12:57:02 +0200 The same occurs on a W2K3 Terminal server. It seems you cannot use ownerdrawing on an XbpListBox, on a terminal server. Errorlog is identical. Regards, Frans Vermeulen | |

Frans Vermeulen | Re: Ownerdraw, XbpListbox, W2K terminalserver on Tue, 27 May 2008 21:15:34 +0200 Not as far as I am aware of. No code in the drawItem method, No Phil Ide's gradient code. No manifest. The Ownerdraw runs fine on W2K, XP and Vista workstations. On Terminal server it crashes right before or upon creation. The log just indicating it crashes from the event manager, trying to call a NIL:handleevent(xbeP_DrawItem, oPresspace, aInfo) I tried to switch off Ownerdrawing based on Os(...) but since it seems to be a typical TS issue, this appears not to be the solution. ......... Ouch ........ I think I found it: I have hotfixexs 1.90 up to hotfix 11 applied. Hotfix 12 contains a fix: PDR 5702 http://www.alaska-software.com/scripts/waa001.dll?WAA_PACKAGE=PUBLICDTS&WAA_FORM=DISPLAYPDR&PDRID=5702 I'll go and try it tomorrow. Regards & thank you very much, your question made me look at the right place. Frans Vermeulen | |
