if checked, then disable a "Field"

OsmanY22 · 24th August 2006, 13:42

Hi.

I have a custom Page. In this Custom Page, there are some Fields (Label, Text, Password) and Checkbox. Now I want to do, that, when a checkbox is checked, then an of the Fields (Text) should be disabled!

Lood at the Picture "enabled&disabled.jpg"

Thx @all

PHP Code:


			
ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 3" "State"

        StrCpy $OCIP $0

ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 5" "State"

        StrCpy $OCUSER $0

ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 7" "State"

        StrCpy $OCPWD $0

ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 10" "State"

        StrCpy $DINAME $0

ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 12" "State"

        StrCpy $DIUSER $0

ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 14" "State"

        StrCpy $DIPWD $0

ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 16" "State"  

        StrCmp $0 0 done

    ExecWait "$INSTDIR\wrapper\bin\Install_MediaServer.bat" 

    Delete "$INSTDIR\wrapper\conf\password.conf"

done:

First, make sure you have the notify flag set on your checkbox. Then, in the page's callback function, so this: (PS: your original code was missing a backslash between $PLUGINSDIR and the name of your page file.)

code:


Function callback

   push $0

   push $1

   ReadIniStr "$PLUGINSDIR\setup.ini" "Settings" "State"

   ; compare $0 to the field of your checkbox.

   ; (This example assumes field 8 is your checkbox)

   StrCpy $0 8 changestate 0

   ; *** normal callback code goes here ***



   changestate:

   ; the next lines assume that your field to 

   ; gray out is field 9

   ReadIniStr $0 "$PLUGINSDIR\Setup.ini" "Field 9" "HWND"

   ReadIniStr $1 "$PLUGINSDIR\Setup.ini" "Field 8" "state"

   StrCmp $1 1 disable enable



   disable:

   EnableWindow $0 0

   ; and write the value just in case the user returns to this screen:

   WriteIniStr "$PLUGINGSDIR\Setup.ini" "Field 9" "Flags" "DISABLED"

   pop $1

   pop $0

   abort



   enable:

   EnableWindow $0 1

   ; and write the value just in case the user returns to this screen:

   WriteIniStr "$PLUGINGSDIR\Setup.ini" "Field 9" "Flags" ""

   pop $1

   pop $0

   abort   

FunctionEnd

***EDIT: I changed the code above to check for the state of the checkbox and enable/disable as needed. (minor details...)

OsmanY22 · 24th August 2006, 14:41

sorry, but i don't understand, where I should give the function "callback"?

This my Code now ... Field 16 is my checkbox and Field 12 and 14 must be disabled, when this checkbox ist NOT checked.

Do you know, what i mean?

code:


   ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 3" "State"

        StrCpy "$OCIP" $0

      ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 5" "State"

        StrCpy $OCUSER $0

      ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 7" "State"

        StrCpy $OCPWD $0

      ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 10" "State"

        StrCpy $DINAME $0

      ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 12" "State"

        StrCpy $DIUSER $0

      ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 14" "State"

        StrCpy $DIPWD $0

        ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 16" "State"  

        StrCmp $0 0 done

        ExecWait "$INSTDIR\wrapper\bin\Install_MediaServer.bat" 

        Delete "$INSTDIR\wrapper\conf\password.conf"

        done:

I don't forget "/" ... but the editor of PHP doesn't show it.

Any custom page you insert has a show function and a leave function (also called a callback function).

Use them in your page command like this:

code:


Page custom showfunction leavefunction

(in this example, the "leavefunction" is what I'm calling the "callback" function.)

Refer to the documentation and the examples for more info. (${NSISDIR}\examples\InstallOptions\testnotify.nsi offers a good example of how to use page callbacks.)

OsmanY22 · 25th August 2006, 10:29

Thx a lot man!!!

it workssss!!!

FALSE: "$PLUGINGSDIR"
RIGHT: "$PLUGINSDIR"

OsmanY22 · 25th August 2006, 10:37

What does this text mean??

code:


  ; compare $0 to the field of your checkbox.

   ; (This example assumes field 8 is your checkbox)

   StrCpy $0 8 changestate 0

It works with to disable an Field, but i cant continue with the install.

What is the problem??

code:




Function callback

       push $0

       push $1

      ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 3" "State"

        StrCpy "$OCIP" $0

      ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 5" "State"

        StrCpy $OCUSER $0

      ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 7" "State"

        StrCpy $OCPWD $0

      ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 10" "State"

        StrCpy $DINAME $0

      ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 12" "State"

        StrCpy $DIUSER $0

      ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 14" "State"

        StrCpy $DIPWD $0

        

      ReadINIStr $0 "$PLUGINSDIR\setup.ini" "Field 16" "State" 

       StrCmp $0 8 changestate 0

    

       changestate:

       ; gray out is field 14

       ReadIniStr $0 "$PLUGINSDIR\Setup.ini" "Field 14" "HWND"

       ReadIniStr $1 "$PLUGINSDIR\Setup.ini" "Field 16" "state"

       StrCmp $1 0 disable enable

    

       disable:

       EnableWindow $0 0

       ; and write the value just in case the user returns to this screen:

       WriteIniStr "$PLUGINSDIR\Setup.ini" "Field 14" "Flags" "DISABLED"

       pop $1

       pop $0

       abort

    

       enable:

       EnableWindow $0 1

       ; and write the value just in case the user returns to this screen:

       WriteIniStr "$PLUGINSDIR\Setup.ini" "Field 14" "Flags" ""

       pop $1

       pop $0

       abort   

FunctionEnd

Now last question...how can I "disable" more Fields??

I want to disable Filed 12 and 14.

Comperio · 26th August 2006, 14:01

oops! My bad..
It was a typo on my part--sorry 'bout that!

The line

code:


StrCpy $0 8 changestate 0

should have been:

code:


StrCmp $0 8 changestate 0

And thanks for catching my other typo.

Edit:
OsmanY22, I sent you a PM explaining the nuts and bolts of this script a little better so that you'd have a better understanding of how to implement it in your situation.

Please can someone help me! I have a custom page with 2 fields. a checkbox (field 2) and a text box (field 4)

I want to make it so if the checkbox is ticked, the textbox is enabled, and if unticked the textbox is disabled. I have followed code snippets from this forum and yet cannot make it work. I know I am close! Any helpers?

Thanks!

code:


    ; get value of checkbox

   !insertmacro MUI_INSTALLOPTIONS_READ $R4 "OptionDetails.ini" "Field 2" "State"

   ; get the field triggered

   !insertmacro MUI_INSTALLOPTIONS_READ $R0 "OptionDetails.ini" "Settings" "State" 



   ${if} $R0 == "2"  ; if field 2 clicked



         ReadIniStr $R3 "OptionDetails.ini" "Field 4" "HWND"



      ${if} $R4 == "1"



         EnableWindow $R3 1

         WriteIniStr "OptionDetails.ini" "Field 4" "Flags" ""

      ${else}



         EnableWindow $R3 0

         WriteIniStr "OptionDetails.ini" "Field 4" "Flags" "DISABLED"

      ${EndIf}



      abort    ; return to page

   ${EndIf}

ReadIniStr requires a full path. Use $PLUGINSDIR\optionDetails.ini or the MUI macros. Same goes to WriteIniStr.

TheShadowHawk · 21st November 2006, 21:57

Thanks very much kichik! That fixed it for me!
