[Bug 1486] Dynamically created menus do not work in Delphi apps
by Wine Bugs April 1, 2004

April 1, 2004

http://bugs.winehq.org/show_bug.cgi?id=1486 ------- Additional Comments From r.kessel(a)metrodata.de 2004-01-04 06:08 ------- I found a workaround for my own Delphi application. It's a bit ugly, but works fine. If you hide the complete menu before changing it and display it when it is updated it will be workable afterwards. Hide the menu by setting the menu property of the form to nil and restore the pointer later. Maybe we could even find the problem by looking at the difference between hide and restore and a rebuild. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.

[Bug 2139] New: Edit control bug in EDIT_EM_GetLine (multiple lines) for lines with zero length
by Wine Bugs April 1, 2004

http://bugs.winehq.org/show_bug.cgi?id=2139 Summary: Edit control bug in EDIT_EM_GetLine (multiple lines) for lines with zero length Product: Wine Version: 20040309 Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: wine-winelib AssignedTo: wine-bugs(a)winehq.org ReportedBy: r.kessel(a)metrodata.de The EM_GETLINE message handler has a bug in handling multiple line controls when they contain lines with zero length. Problem: Instead of returning an empty line, EDIT_EM_GetLine does nothing and returns the buffer length as the character count. Most likely the problem is in the following section: { LPSTR dst = (LPSTR)lParam; INT ret; ret = WideCharToMultiByte(CP_ACP, 0, src, line_len, dst, dst_len, NULL, NULL); if(!ret) /* Insufficient buffer size */ return dst_len; if(ret < dst_len) /* Append 0 if enough space */ dst[ret] = 0; return ret; } In case that line_len is zero WideCharToMultiByte returns correctly zero, but this is treated as an insufficient buffer size. Possible solution: { LPSTR dst = (LPSTR)lParam; INT ret; if(line_len) { ret = WideCharToMultiByte(CP_ACP, 0, src, line_len, dst, dst_len, NULL, NULL); if(!ret) /* Insufficient buffer size */ return dst_len; } else { ret = 0; } if(ret < dst_len) /* Append 0 if enough space */ dst[ret] = 0; return ret; } -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
