Not equal comparison with strings

[repuust]

When using the LogicLib.nsh, is it just me, or can you not do "not equal" with two strings? I've tried to do something like:

${If} $DB_PWD <> $0
MessageBox MB_ICONEXCLAMATION|MB_OK "The two passwords do not match"
Abort
${EndIf}

or something similar a few times. It will never run the inner block of code, regardless of whether $DB_PWD and $0 are equal or not. I've now got these scatterered throughout my code:

${If} $DB_PWD == $0
; This is hack, because for some reason you can't do <> comparison with strings
${Else}
MessageBox MB_ICONEXCLAMATION|MB_OK "The two passwords do not match"
Abort
${EndIf}

I can't believe I'm the first to find this, but I can't find any post or help on something like this. The LogicLib.nsi sample compares integers, but not strings. Note, it works just fine with integers.
