Short pathnames (not 8.3)

yugemos · 14th June 2003, 01:52

I am having trouble getting a full path name (ie not 8.3) for my installer. For some unknown reason, the software I'm configuring (PHP) doesn't cope with ~'s too well, so I need to write to the configuration file using long path names.

I am using NSIS v2.0b3 and this is the code extract that does not seem to be functioning (the ReplaceInFile macro is from the NSIS Archive)

code:
GetFullPathName $1 $TEMP

!insertmacro ReplaceInFile "$INSTDIR\Apache\php.ini" "§Temp§" "$1"

However, this writes the following to php.ini

Quote:

session.save_path = C:\DOCUMEN~1\ADMINI~1\LOCALS~1\Temp

Is this how GetFullPathName should be used?
Any suggestions welcome! The full file is attached.

Thanks in advance,
Stefan Norman

Note that the GetFullPathName command does something else, it does not convert short files names to long file names.

You can call the GetLongPathName API using the System plug-in. However, this is not supported on Windows 95/NT4. If you want it to be compatible with Windows 95/NT4, you have to find another solution.

Sorry, I'm new to NSIS and I haven't used windows for tasks like this before.
Could you please explain how I would do this exactly?

lol even I didn't understand

Well, you can first check all about the APIs...
then... check the info in ${NSISDIR}\Contrib\System
In there you'll find the info. about the system.dll plugin...
Also check in this web archive about how to use extra features
about the plugin...

This will only work on Windows 98+ and 2000+.

code:
StrCpy $0 "C:\Progra~1"

StrCpy $1 ""

System::Call "Kernel32::GetLongPathNameA(t '$0', &t .r1, i \

  ${NSIS_MAX_STRLEN}) i .s"

Pop $0

IntCmp $0 ${NSIS_MAX_STRLEN} +2 +2 0

  Abort "failed!"

DetailPrint "$0 - $1"
