Custom page checkbox {IF} logic

I have a checkbox on a custom page and am reading it in as so:
ReadINIStr $R1 $INI "Field 2" "State"

However I am having problems knowing what state the buton is in:

${If} ${SectionIsSelected} $R1
MessageBox MB_OK 'Radio selected'

I've tried it many ways.

What is the easiest way to detect true/false of a radio button?

SectionIsSelected is for NSIS Sections.


${If} $R1 = 1
MessageBox MB_OK 'Radio selected'
${EndIf}

Ah, thank you.

It always seems to return 0 or the value of state when set, regardless of the radio box checked or not.

ini file:
[Field 4]
Type=RadioButton
Left=60
Right=-220
Top=50
Bottom=80

read in :
ReadINIStr $R4 $INI "Field 4" "State"

your new code:
${If} $R4 = 1
MessageBox MB_OK 'Radio selected'
${EndIf}

The message only appears if I change the if to 0 instead of 1.

any ideas?

Where is this code to read the value of the page?
It can't be directly after the InstallOptions call, but in the pages' Leave function.

The ini read is in the LeaveCustom function that I added to the Custom page declaration.

The function seems to be called OK, as im able to get a string from another field i've added to $R1

The IF statement is in the middle of a Section which gets called ok as I can get the message box to popup if i set the condition to 0 instead of 1.

Please attach your script. There isn't any more I can do without it.

Ok, thank you very much for taking the time.

It's basically a slightly modified Modern UI - HeaderBitmap example.

the testCustom ini :

[Settings]
NumFields=7

[Field 1]
Type=Label
Left=5
Right=-220
Top=10
Bottom=18
Text=Path :

[Field 2]
Type=DirRequest
Left=105
Right=-20
Top=8
Bottom=21
state=c:\temp\folder

[Field 3]
Type=Label
Left=5
Right=-250
Top=60
Bottom=80
Text=Visual Studio :

[Field 4]
Type=RadioButton
Left=60
Right=-220
Top=50
Bottom=80

[Field 5]
Type=Label
Left=110
Right=-150
Top=60
Bottom=80
Text=Dev C++ :

[Field 6]
Type=RadioButton
Left=155
Right=-50
Top=50
Bottom=80

[Field 7]
Type=GroupBox
Left=0
Right=-1
Top=45
Bottom=85
Text=" IDE "

Your script was quite a mess really.
You were extracting two copies of testCustom.ini; displaying the InstallOptions dialog from one and then reading values from another!

Also, no need to declare Var INI.
If you need constants, use !define.

Wow, that's some level of support I must say. Quite amazing!

And again, thank you for your time in resolving my problem.
