Summary | 0006226: TJvComboBox.Add raises Access Violation when CharCase<>ecNormal | ||||
Description | If I put CharCase=ecUpperCase, then the first addition of an item to the combobox will raise an access violation, other additions are running ok. Severity : causes Acces Violation, this is the problematic part and it was working in Delphi 2010 (old version of JVCL), so it's hard to find when migrating to XE4/XE5 otherwise, its easily workaroundable. version displayed in about box of delphi for JVCL is 3.48 | ||||

Fixed in master branch. The problem is this: <quote> Comclt32.dll version 5.0 or later: If CBS_LOWERCASE or CBS_UPPERCASE is set, the Unicode version of CB_ADDSTRING alters the string. If using read-only global memory, this causes the application to fail. </quote> A string literal is read only, so "cb.Add('abc')" causes a access violation while "cb.Add('ab' + S)" doesn't. The fix is to call UniqueString on the specified string. |
