Checking dialog checkboxes

[Afrow UK]

This is a checkbox control on an exe dialog (not InstallOptions)

Is there a WindowsMessage to do this, because I'd rather not have to use the System plugin with BM_SETCHECK (http://www.minigui.com/api_ref/group...__msgs.html#a1)

Cheers

Did you forget SendMessage NSIS command? It does exactly the same thing as using SendMessage from System plugin (except it can't get parameters from "wparam" and "lparam", it just set).

Yeh SendMessage will do it. I'ved used it for working with checkboxes as follows...

PHP Code:

SendMessage $R1 ${BM_SETCHECK} 1 0 


To set the checkbox state. I believe changing the 1 to 0 will turn the checkbox off.

PHP Code:

SendMessage $R1 ${BM_GETSTATE} 0 0 $R2 


To get the checkbox state and $R2 will contain either 1 or 0 depending on if the checkbox is checked or not.

Yes, but wheres the BM_SETCHECK define? It's not in WinMessages.nsh (not the one that I have anyhow)

No it isn't you have to add it. It's in some windows header file if you really want to look it up. Just type in BM_SETCHECK in any source file in visual studio and select "go to definition". That'll give you the value or just copy the following...

!define BM_GETSTATE 0x00F2
!define BM_SETCHECK 0x00F1

That's what I've been trying to find (must reinstall VB!)

Thanks

Thanks rsegal.Now I have another question: how can I send message to change a droplist box state?A sample ini file like this

PHP Code:

[Settings]
NumFields=1

[Field 1]
Type=Droplist
Text=Droplist
State=1
ListItems=1|2|3
Left=77
Right=174
Top=27
Bottom=119 


Default state is "1",I want to send a message cause it change to "2".

[deguix]

PHP Code:

!define CB_FINDSTRINGEXACT          0x0158
!define CB_SETCURSEL                0x014E

SendMessage $hCtrl ${CB_FINDSTRINGEXACT} -1 "String to be selected" $0
SendMessage $hCtrl ${CB_SETCURSEL} $0 "" 


[bluenet]

I test deguix's code,but not work.These is my code

PHP Code:

Name                 "Test"
OutFile              ".\test.exe"
Caption              "Test"
SetCompressor        lzma
ShowInstDetails      show
!include             MUI.nsh

  Page custom SetCustom LeaveCustom
    
  !insertmacro MUI_PAGE_INSTFILES
  !insertmacro MUI_LANGUAGE English

Section
SectionEnd

Function SetCustom
  InstallOptions::initDialog /NOUNLOAD "$PLUGINSDIR\test2.ini"
    Pop $9
     InstallOptions::show
FunctionEnd

; --------------------------------------
!define CB_FINDSTRINGEXACT          0x0158 
!define CB_SETCURSEL                0x014E 

Function LeaveCustom
    ReadINIStr $R0 "$PLUGINSDIR\test2.ini" Settings State
  StrCmp $R0 0 validate  
  StrCmp $R0 2 droplist  
    Abort
    
    droplist:
    ReadINIStr $1 "$PLUGINSDIR\test2.ini" "Field 2" State
  GetDlgItem $R1 $9 1200
    SendMessage $R1 ${CB_FINDSTRINGEXACT} -1 $1 $0 
    SendMessage $R1 ${CB_SETCURSEL} $0 ""    
    ;EnableWindow $R1 0
    Abort
    
    validate:
FunctionEnd    

Function .onInit
  InitPluginsDir
    File "/oname=$PLUGINSDIR\test2.ini" ".\test2.ini"
FunctionEnd 


And these is my ini file

PHP Code:

; Ini file generated by the HM NIS Edit IO designer.
[Settings]
NumFields=2

[Field 1]
Type=Droplist
Text=Droplist
State=1
ListItems=1|2|3
Left=61
Right=218
Top=6
Bottom=100

[Field 2]
Type=Droplist
Text=Droplist
Flags=NOTIFY
State=1
ListItems=1|2|3
Left=62
Right=220
Top=60
Bottom=151 


I want droplist 2 control droplist 1.What wrong for me?

[deguix]

I thought it would not work because of that -1 I put for ${CB_FINDSTRINGEXACT}. MSDN says that if wparam is -1 it would search the whole list, but that doesn't happen. Put 0 on its place.

[bluenet]

I replaceed -1 with 0,but still not work.

[deguix]

Hmmm... Aparently there is a problem with SendMessage from NSIS. Everytime I change the number in wparam and/or lparam it should return the correct index of the item (it now returns 0). This is the correct (tested this time):

code:
!define CB_FINDSTRINGEXACT          0x0158 

!define CB_SETCURSEL                0x014E 



  System::Call 'user32::SendMessageA(i R1, i ${CB_FINDSTRINGEXACT}, i -1, t r1)i .r0'

  System::Call 'user32::SendMessageA(i R1, i ${CB_SETCURSEL}, i r0,)'

[bluenet]

I got a idear to do it

PHP Code:

!define CB_GETCURSEL                0x0147 
!define CB_SETCURSEL                0x014E
GetDlgItem $R1 $HWND 1201
SendMessage $R1 ${CB_GETCURSEL} -1 0 $R2    
GetDlgItem $R1 $HWND 1200
SendMessage $R1 ${CB_SETCURSEL} $R2 0
