NetDDE Passwords Must Be Uppercase when Using NDDEShareAdd (94640)
The information in this article applies to:
- Microsoft Windows for Workgroups 3.1
- Microsoft Windows for Workgroups 3.11
This article was previously published under Q94640 SUMMARY
If you receive an invalid password error when accessing a shared ClipBook
page on another machine, the password may not have been entered from the
user interface provided in ClipBook. The standard user interface
automatically converts all entries to uppercase characters, and the
programmable interface NDDEShareAdd does not. If the password was not
entered in uppercase characters, the passwords, though identical in all
other respects, do not match.
MORE INFORMATION
All passwords must be in uppercase characters before calling NDDEShareAdd.
The application program interface (API) does not change the password
characters to uppercase automatically. The API encrypts the passwords in
lowercase characters. On the server, the password characters entered in the
password dialog box are automatically changed to uppercase. The encrypted
versions of both passwords are compared as binary, and if different strings
are encrypted, the comparison fails.
Tests that use a user interface to have the user enter the password always
work because that user interface changes the password characters to
uppercase before calling NDDEShareAdd.
NOTE: Only applications with mixed-case strings in their data or resources
exhibit this problem.
NDDEShareAdd is a NetDDE command. This only affects users that have created
their own NetDDE applications, are using a third-party NetDDE application,
or are accessing the NetDDE interface by using an applications DDE
interface.
