DOCUMENT:Q75500 10-JUN-1999 [win16sdk] TITLE :INFO: Altering Edit Control Strings in Place May Cause UAE PRODUCT :Microsoft Windows Software Development Kit PROD/VER:WINDOWS:3.1 OPER/SYS: KEYWORDS:kb16bitonly kbCtrl kbEditCtrl kbSDKPlatform ====================================================================== 3.00 3.10 WINDOWS kbprg ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows Software Development Kit (SDK) 3.1 ------------------------------------------------------------------------------- SUMMARY ======= Declaring an Edit control with certain styles, and altering the text, may have undesirable effects. Depending upon whether or not pointers to the text are passed to other functions, changing the text in place may generate an Unrecoverable Application Error (UAE). Declaring an Edit control with any of the following styles, ES_LOWERCASE, ES_UPPERCASE, or ES_OEMCONVERT, and calling either SetWindowText (hEdt,lpstr) or SetDlgItemText (hDlg, editID, lpstr) alters the string in place. Calling either one of the previously mentioned functions to alter a string contained in a code segment, which is labeled PURE in the corresponding .DEF file, will result in a UAE.
