call single InstallOptions Dialog n times.

[coderwolf]

I have a dialog that will be called n times (up to a maximum of 75 times)(number determined by the user). But when I call it from the create section of the Pages custom declaration it only shows the dialog one time.

Page custom fnc_FtpProfile_PreShow

Function fnc_FtpProfile_PreShow
${For} $R1 1 $NoTimes
Call fnc_FtpProfile_Show
${Next}
FunctionEnd

When I try to loop the page declaration I get an error from the compiler.

${For} $R1 1 $NoTimes
Page custom fnc_FtpProfile_PreShow
${Next}

Due to the possible high number of profiles, it is very prohibitive to manually code 75 instances of the code in a file. Is there any way I can loop the showing of dialogs?
This is an installation for a system where some installs actually already have over 60 profiles.

I have not. If I understand this right, For my implementation, I would have to define a custom Abort function. Similar to the "Special Usage" section?

This may take a bit of digestion to fully understand.

I am going to have to eat my words here. I just learned that nsdialogs is not really a subset of the InstallOptions set. I had somehow give myself that impression on previous doc readthroughs.

Is there any way to replicate the page loop structure I mentioned earlier using the nsdialogs system? (that is the way I have my form defined currently)

Showing 60 pages in a installer is insane!

There are several ways to show the same page several times, they all suck:

!include LogicLib.nsh
var test_max
var test_num
!macro InitPageLoopTest
StrCpy $test_num 0
!macroend
!macro _ShowAnotherTestPage _a _b _t _f
IntOp $test_num $test_num + 1
IntCmp $test_num $test_max `${_f}` `${_t}` `${_f}`
!macroend
!define ShowAnotherTestPage `"" ShowAnotherTestPage ""`

!include nsDialogs.nsh

I would recommend that you just have 2 custom pages. Page 1 would contain a list of profiles and page 2 would edit the selected profile. You would then skip the 2nd page if no profile is selected or jump back to page 1 after editing a profile...

trying to follow option 2 for a pattern. The code you gave is repeating the dialog. My code is showing the dialog one time. I am missing something. Below is my code.

!include MUI2.nsh
!include "nsDialogs.nsh"
!include "LogicLib.nsh"
!include "FtpProfile.nsdinc"

Var max_Profiles ; Maximum number of profiles
Var ndx_num ; index of where we are in the Profile Loop

Var ProfileName
Var LclPSDir
Var RmtPSDir
Var LclConDir

Page components
Page custom fnc_FtpProfile_PreShow fnc_FtpProfile_AfterShow

Section /o "Config Profiles" Profiles ;FTPCFGXX.CMD {Steps 16-19, 23}
SectionIn 1 7
;StrCpy $max_Profiles 15
SectionEnd

!macro _ShowAnotherFTPPage _a _b _t _f
IntOp $ndx_num $ndx_num + 1
IntCmp $ndx_num $max_Profiles `${_f}` `${_t}` `${_f}`
!macroend
!define ShowAnotherFTPPage `"" ShowAnotherFTPPage ""`

!macro InitFTPPageLoop
StrCpy $ndx_num 0
StrCpy $max_Profiles 15
!macroend

Function fnc_FtpProfile_PreShow
SectionGetFlags ${Profiles} $R0
IntOp $R0 $R0 & ${SF_SELECTED}
IntCmp $R0 ${SF_SELECTED} show

Abort

show:
GetDlgItem $0 $hwndparent 1
