The window only displays text. You can't have it showing a custom page. If you want to have a custom page with help information on it, either put it in another executable and extract and run it or add a custom page and only show it when your help button is pressed (don't need HelpButton for this).

I dont entirely understand but isn't there possibility to create dialog with nsDialogs?

[jiake]

You can use nsWindows, it could create dialog box.

think for your answers,

but my problem is "how could I call a page from a help button that will contain components such as GroupBox and Label".

1. Add a help button (if it's via Resource Hacker then use ButtonEvent plug-in on it)
2. On click, set a global Var (i.e. $ShowHelp) to 1
3. Jump to your help page

In your help page's show function, call Abort if $ShowHelp != 1. Also ensure you reset $ShowHelp to 0 when you leave the help page.

The only issue really is that when you enter the help page, the back or next buttons won't take you back to where you were when you clicked the Help button. For that reason to be honest it'd be easier to have a pop-up.

Hi, in fact am little bit confused here, the pop-up you mentioned earlier you mean a message_box or a whole custom page? cause this last one always ,as you know ,contains the three useless button, (next,back and cancel ).
thnks

If you want a custom page pop-up, use nsWindows (as mentioned already) which is a modified version of nsDialogs. The other option as I said would be to bundle another NSIS EXE which has one custom page and extract and run that (probably messier than nsWindows).

Create a pop-up dialog with web control, list view and tree view with checkboxes.


See this example script.

hi, please i use the help button , but i have a problem,
when I click in my help button I lost my parent page and I have a other page,
how can I still in my parent Page.
my parent page is a custom page.

I use this code :
when i click in my button help i call "CreateHelpButton"

Function CreateHelpButton

nsDialogs::Create 1018
Pop $0

StrCmp $0 error 0 +2
Abort
call CreateCustomDialog

nsDialogs::Show

FunctionEnd

Function CreateCustomDialog

Pop $0
nsWindows::Create $0 0 ${WS_VISIBLE}|${WS_SYSMENU}|${WS_CAPTION} "Help dialog" 1018
Pop $1

${NSW_SetWindowSize} $1 500 350
${NSW_CenterWindow} $1 $HWNDPARENT

StrCmp $1 error 0 +2
Abort

EnableWindow $0 0

${NSW_CreateGroupBox} 3% 4% 90% 10% "blabal"
Pop $R0
${NSW_CreateLabel} 8% 8% 70% 5% "blabal"
Pop $R1

${NSW_CreateGroupBox} 3% 19% 90% 10% "blabal"
Pop $R2
${NSW_CreateLabel} 8% 23% 70% 5% "blabal"
Pop $R3

${NSW_CreateGroupBox} 3% 34% 90% 10% "blabal"
Pop $R4
${NSW_CreateLabel} 8% 38% 70% 5% "blabal"
Pop $R5

${NSW_CreateGroupBox} 3% 49% 90% 10% "blabal"
Pop $R6
${NSW_CreateLabel} 8% 53% 70% 5% "blabal"
Pop $R7

${NSW_CreateGroupBox} 3% 64% 90% 10% "blabal"
Pop $R8
${NSW_CreateLabel} 8% 68% 70% 5% " blabal"
Pop $R9

${NSW_CreateButton} 50% 84% 10% 5% "OK"
Pop $R1

${NSW_OnClick} $R1 CloseCustomDialog
nsWindows::Show
FunctionEnd

Function CloseCustomDialog

SendMessage $1 ${WM_CLOSE} 0 0

FunctionEnd

Send WM_CLOSE to the window (the handle returned from ::Create) using SendMessage.

Stu

[jiake]

In this example I use $0 multiple times for dialog handle and other controls. If you want to send message to dialog handle, make sure the value of the variable for dialog's handle in dialog creation function is always the same, use the variable only once.

nsWindows::Create $HWNDPARENT 0 ${WS_VISIBLE}|${WS_SYSMENU}|${WS_CAPTION} "Pop-up dialog" 1018
Pop $0 # handle of dialog

If you use $0 for dialog handle, the variable wouldn't be used again in all event funtions of controls on this dialog. I think you should know.

In your button event use:
SendMessage $handle ${WM_CLOSE} 0 0
Where $handle has been mentioned already.

Hi

I try to do this for my close button

Function help
${NSW_CreateButton} 50% 84% 10% 5% "OK"
Pop $R1

${NSW_OnClick} $R1 CloseCustomDialog

nsWindows::Show
FunctionEnd

Function CloseCustomDialog

SendMessage $HWNDPARENT ${WS_CLOSE} 0 0

FunctionEnd

and it's still not working

Please help me.

It's WM_CLOSE not WS_CLOSE. Where did you get WS_CLOSE from? You should be seeing a compiler warning "unknown variable/constant "{WS_CLOSE}" detected, ignoring" if you haven't defined WS_CLOSE. Don't ignore ANY compiler warnings.

Stu

[hanenjom]

if i use ${WM_Close} , i will close the window for help and the parnet window ...

[Afrow UK]

That's because you're using $HWNDPARENT which is a handle to the NSIS window. You want the handle returned from nsWindow::Create as we have already explained.

[hanenjom]
