Trouble with GetFullPathName

[geoffrey_4js]

Hello,

I'm using NSIS 2.06 and there's a place in my code where GetFullPathName doesn't seem to work.

I'm using the MUI interface and call the MUI_DIRECTORY_PAGE this way :

code:
!define MUI_PAGE_CUSTOMFUNCTION_PRE 			Defaults.onPreDirPage

!define MUI_PAGE_CUSTOMFUNCTION_LEAVE 		Defaults.onLeaveDirPage

!insertmacro MUI_PAGE_DIRECTORY

In the Defaults.onLeaveDirPage, I need to be sure that $INSTDIR is a full path so I do :

code:
Function Defaults.onLeaveDirPage

  Push $R0 ; The return value of the function 'FileOrDirStatus'

  Push $R1



 GetFullPathName $INSTDIR $INSTDIR



  ; Determines the status of the installation directory

  ${FileOrDirStatus} $R0 "$INSTDIR"

	${Select} "$R0"

	  ${Case2} "empty" "does not exist"

	  ${CaseElse}

	    ${IfCmd} MessageBox MB_YESNO|MB_ICONQUESTION $(Defaults_Ask_InstDirNotEmpty) IDNO ${||} StrCpy $ABORT_FLAG "true" ${|}

	${EndSelect}



  ${Unless} "$ABORT_FLAG" == "true"

	  WriteIniStr "$PLUGINSDIR\${UNINSTALL_INI_FILE}" "Main.data" "InstallDirectory" "$INSTDIR"

  ${EndUnless}



  Pop $R1

  Pop $R0

	Call Defaults.abortIfRequired

FunctionEnd

But this doesn't work as I've always INSTDIR as a short path if I type it as a short path on the MUI_DIRECTORY_PAGE.

I've try the following things without success:

1.
GetFullPathName $R1 "$INSTDIR"
StrCpy $INSTDIR $R1

2.
GetFullPathName $R1 $\"$INSTDIR$\"
StrCpy $INSTDIR $R1

3.
GetFullPathName $INSTDIR "$INSTDIR"

I can't see what to try now to make this work. Any idea ?

Call GetLongPathName using the System plug-in.

Thank you Kichik, I'll try this.
