Displaying $InstDir in a textbox

bSecRes · 19th July 2003, 19:10

Slashes get removed.

I wanted to display a custom page right before the InstFiles page (mostly because I wanted an Install button). I decided to use this page to review the users selections during the install. I have a multiline textbox and I try to do this:
!insermacro MUI_INSTALLOPTIONS_Write "readytoinstall.ini" "Field n" "State" "Directory To Install To:\r\n\t$InstDir\r\n\r\n" but the output in the textbox is
Directory To Install To:
C:Program FilesFolder Name
('C:' and 'Program Files' may not actually be the user selection obviously, I just used those in this example.)

I checked the $InstDir variable and it still has slashes before and after I use it here but they won't show up in the textbox. Ultimately, the program gets installed correctly.

I had originally written my post as a reply to yours but then I wasn't sure what it was exactly you were trying for so I posted a new thread.

Later I escape the slashes in a CopyFiles thing and it doesn't work. I'll keep you all up to date on my progress.

Edit:
Guide to escaping things in NSIS
$$ is $
$\" is "
&& is &
\\ is \

The convention appears to be double everything except the quote because that means null? If some other character has a natural meaning in it's double form like the quote then it will need to be escaped with $\x x being the character with natural double meaning.

Use the ConvertBStoDBS function on the NSIS archive for placing paths in an IO page.

Does not work so far - or am i wrong with this?

[Field 7]
Type=DirRequest
Left=10
Right=300
Top=95
Bottom=108
State=$R0

bSecRes · 19th July 2003, 22:56

Brummelchen, according to Afrow, you would want to do something like this:

Push $R0
Call ConvertBStoDBS
Pop $R0
WriteINIStr "SomeFile.ini" "Field 7" "State" $R0

You cannot set the value of state to $R0 in a text editor and then, once the Field is processed, have the current value of $R0 appear there.

Afrow UK · 19th July 2003, 23:08

bSecRes is correct.

no fortune

code:


page custom selectsaveitems



Function .onInit

  ;Extract InstallOptions INI Files

  !insertmacro MUI_INSTALLOPTIONS_EXTRACT "menu01.ini"

  !insertmacro MUI_INSTALLOPTIONS_EXTRACT "menu02a.ini"

  !insertmacro MUI_INSTALLOPTIONS_EXTRACT "menu03a.ini"

  !insertmacro MUI_INSTALLOPTIONS_EXTRACT "menu02b.ini"

FunctionEnd



Function selectsaveitems

  Push $INSTDIR

    Call ConvertBStoDBS

  Pop $R0

  WriteINIStr "menu02a.ini" "Field 7" "State" $R0

  !insertmacro MUI_INSTALLOPTIONS_DISPLAY "menu02a.ini"

FunctionEnd

Afrow UK · 19th July 2003, 23:19

Should be:

code:
Function .onInit

  ;Extract InstallOptions INI Files

  !insertmacro MUI_INSTALLOPTIONS_EXTRACT "menu01.ini"

  !insertmacro MUI_INSTALLOPTIONS_EXTRACT "menu02a.ini"

  !insertmacro MUI_INSTALLOPTIONS_EXTRACT "menu03a.ini"

  !insertmacro MUI_INSTALLOPTIONS_EXTRACT "menu02b.ini"

FunctionEnd



Function selectsaveitems

  Push $INSTDIR

    Call ConvertBStoDBS

  Pop $R0

  !insertmacro MUI_INSTALLOPTIONS_WRITE "menu02a.ini" "Field 7" "State" $R0

  !insertmacro MUI_INSTALLOPTIONS_DISPLAY "menu02a.ini"

FunctionEnd

Doing a
WriteINIStr "menu02a.ini" "Field 7" "State" $R0
will write it to C:\menu02a.ini, because you did not specify the file path.
With MUI_INSTALLOPTIONS_WRITE, the macro puts the file path in for you (which is $PLUGINSDIR\menu02a.ini)

This works, thx.

But i dont need "ConvertBStoDBS" any longer - the directory is shown proper without.

But there is something strange - the content of this page is shown after a second intermission (blank page) - huh, thats Mcafee - if deactivated its fast. grmpf - operation must be inside RAM.

aha - IC - i put that line somewhere before (.oninit) - now it's fast again

Afrow UK · 19th July 2003, 23:34

The \\ \ problem must have been an old IO issue, and must have been fixed in latest (or a recent) CVS.

-Stu

bSecRes · 19th July 2003, 23:35

Still an IO issue, just not with DirRequest fields.

Brummelchen · 20th July 2003, 00:19

jep it is
i used your idea for a pre-install page and get no "\"

Afrow UK · 20th July 2003, 10:46

"\" becomes "" in labels.
"\" stays as "\" in anything else (text boxes, dirrequest etc)

kichik · 20th July 2003, 11:25

It's not an issue, it's by design. It is this way so you can use line breaks in labels. The unfortunate side affect is the need to double every black slash when writing to labels.

Brummelchen · 8th September 2003, 02:52

i tried to use this function but i had a minor problem that i have to be compatible to my "version 1" which has a "\" at each path infomation

eg
c:\programs\
and not
c:\programs

ConvertBStoDBS has bug inside which converts
c:\programs\
to
c:\programs\c:\programs\

Not familiar with the code i wrote the following script which is not comfortable but which does it better.

maybe someone can use it...

code:


Function ConvertBStoDBS2

  Exch $R0 ;input string

  Push $R1 ;length string

  Push $R2 ;output string

  Push $R3 ;temp string

  Push $R4 ;counter

  Strlen $R1 $R0

  StrCmp $R1 "0" done

  StrCpy $R2 ""

  StrCpy $R4 "0"

loop:

  StrCpy $R3 $R0 1 $R4

  StrCmp $R3 "\" "0" nobs

    StrCpy $R2 "$R2$R3"

  nobs:

  StrCpy $R2 "$R2$R3"

  IntOp $R4 $R4 + 1

  IntCmp $R4 $R1 loop loop "0"

  StrCpy $R0 $R2

done:

  Pop $R4

  Pop $R3

  Pop $R2

  Pop $R1

  Exch $R0 ;output string

FunctionEnd
