Regedt32.exe splits a string that is longer than 1,024 characters by inserting a null character within the string after 1,024 characters. If you open a REG_MULTI_SZ value that has a string that is longer than 1,024 characters and click OK to save it, the string is split after 1,024 characters and a null character is inserted.


When Regedt32.exe reads from the dialog box, strings that are longer than 1,024 characters are truncated because EM_GETLINECOUNT and EM_LINEINDEX are being used, which return only the length of the first line. Strings longer than 1,024 bytes are treated as multiple-line strings.
