In the page's Leave function, use ReadINIStr to retrieve the Text string, and then write it to the registry using WriteRegStr.

sry, don't know where the documentation for that is, can you put it in one fo the example scripts so that I can figure out where it goes, Thx alot

ReadINIStr and WriteINIStr are in the NSIS documentation.
For example:

Page Custom customPage customPageLeave



Function customPageLeave

 Push $R0

  ReadINIStr $R0 "$PLUGINSDIR\ioFile.ini" "Field 1" "Text"

  WriteRegStr HKCU "Software\MyApp" "Blah" "$R0"

 Pop $R0

FunctionEnd

It is creating the registry entryis now but it isn't putting anything in them. Thx for the help but I must be missing something.

Function customPageA

!insertmacro MUI_HEADER_TEXT "Registration" "$(TEXT_IO_SUBTITLE)"

!insertmacro MUI_INSTALLOPTIONS_DISPLAY "registry.ini"

 Push $R0

  ReadINIStr $R0 "$PLUGINSDIR\registry.ini" "Field 2" "Text"

  WriteRegStr HKCU "Software\AirSnare" "UserName" "$R0"

 Pop $R0

 Push $R1

  ReadINIStr $R0 "$PLUGINSDIR\registry.ini" "Field 4" "Text"

  WriteRegStr HKCU "Software\AirSnare" "Serial" "$R1"

 Pop $R1

FunctionEnd

Same INI as above

You are reading from INI file into $R0, but writing variable $R1 to registry.

OK, Thx but still there is nothing in the data field of the registry key



Function customPageA

!insertmacro MUI_HEADER_TEXT "Registration" "$(TEXT_IO_SUBTITLE)"

!insertmacro MUI_INSTALLOPTIONS_DISPLAY "registry.ini"

 Push $R0

  ReadINIStr $R0 "$PLUGINSDIR\registry.ini" "Field 2" "Text"

  WriteRegStr HKCU "Software\AirSnare" "UserName" "$R0"

 Pop $R0

 Push $R0

  ReadINIStr $R0 "$PLUGINSDIR\registry.ini" "Field 4" "Text"

  WriteRegStr HKCU "Software\AirSnare" "Serial" "$R0"

 Pop $R0

FunctionEnd



[Settings]

[Field 2]

This code needs to go in the page's Leave function:



 Push $R0

  ReadINIStr $R0 "$PLUGINSDIR\registry.ini" "Field 2" "Text"

  WriteRegStr HKCU "Software\AirSnare" "UserName" "$R0"

  ReadINIStr $R0 "$PLUGINSDIR\registry.ini" "Field 4" "Text"

  WriteRegStr HKCU "Software\AirSnare" "Serial" "$R0"

 Pop $R0

User input from the InstallOptions dialog are not saved to the INI file until after the user leaves the page. That's why you aren't getting any data.

Declare the Leave function like so:
Page Custom customPageA customPageALeave

can you show me what it should look like, please? Thx

Custom pages and registry

hello Installers,

I have the same problem that you are faceing .
this is a small piece of script

Function SetContentServer
Push $R0
InstallOptions::dialog $PLUGINSDIR\ContentServer_Name.ini
Pop $R0
ReadINIStr $1 "$PLUGINSDIR\ContentServer_Name.ini" "Field 2" "Text"
FunctionEnd

Function SetContentServerLeave
; Push $1
WriteRegStr HKLM "Software\Legato\ContentServer" "ServerName" "$1"

FunctionEnd

If i put the text from the Page properties before compilation it writes into the registry. but If i take it from the user at runtime it does not.

Wht could be the issue?
why does "Var varname" variable decleration not work ?

Your help will be appreciated.

Regards

Parag

The leave function is called when the user clicks the next button, before the InstallOptions::dialog call returns. Simply write the value to the registry right after you read it in SetContentServer.

While not vastly experienced in custom pages, I do have *one* and use a slightly different model... 🙂

I use an .onInit to check the registry for an existing value for my field - if it is present, I directly update the corresponding field in the [now expanded] INI file.

BTW, since it makes sense for my case, I use the install options length-validating feature to enforce the length restrictions for my data entry field. This blocks the user from proceeding past that page until the restrictions are satisfied.

Then, in the body of the installer section - actually, just before it completes - I do a MUI_INSTALLOPTIONS_READ to get the value of the field, and save it to the registry with a WriteRegStr.

I am posting this both to make sure that my approach is sound (it does seem to work), and to mention that using the Leave function can have the side-effect of making a registry change (in the case described above) even if the user chooses to back out of (abort) the install...

Dragon_ZMarch 11, 2005 at 10:21 PM#

this is all wonderful info and I hope to put it in my next installer, however, where should I place "Page Custom customPageA customPageALeave ", Thx

RDaneelMarch 11, 2005 at 10:35 PM#

The "page custom..." would go in the midst of your "!insertmacro MUI_PAGE*" statements.

It is just saying that you have a custom page and that it has both Enter and Leave functions defined. The precise placement determines where in the sequence of pages making up your installer it appears.

tried it and got this error and it won't create any .exe now

Error: resolving leave-page function "customPageALeave" in install pages

Note: uninstall functions must begin with "un.", and install functions must not

Error - aborting creation process

Any Ideas? Thx

Afrow UKMarch 12, 2005 at 1:40 PM#

It means you haven't declared the customPageALeave Function 😁

You need to do it like:
Function customPageALeave
# ... code here ...
FunctionEnd

Dragon_ZMarch 12, 2005 at 3:15 PM#

ok it actually made the Installer but now it still isn't writing the registry keys. See included zip with all the code and .ini's, thx for any help you can provide

Afrow UKMarch 12, 2005 at 7:58 PM#

Put "MessageBox MB_OK $R0" under the first ReadINIStr in your Leave function to see what the value of $R0 is.

Also you don't need the Pop and Push in the middle.

Dragon_ZMarch 12, 2005 at 10:35 PM#

it isn't capturing the text put in the boxes, nothing is diplayed in the popup

Afrow UKMarch 12, 2005 at 10:36 PM#

Oh wait, if you're reading from a Text field, then you ReadINIStr from "State" not "Text"
