Checking dialog checkboxes
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...

SendMessage $R1${BM_SETCHECK} 1 0 

>

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


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


***93;

>NumFields=1


>***91;Field 1***93;

>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".

define CB_FINDSTRINGEXACT          0x0158

>!define CB_SETCURSEL                0x014E


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

SendMessage $hCtrl${CB_SETCURSEL} $0 ""

>OutFile              ".\test.exe"

>Caption              "Test"

>SetCompressor        lzma

ShowInstDetails      show

>!include             MUI.nsh


  Page custom SetCustom LeaveCustom

    

 !insertmacro MUI_PAGE_INSTFILES

 !insertmacro MUI_LANGUAGE English

SectionEnd


>Function SetCustom

  InstallOptions::initDialog /NOUNLOAD "$PLUGINSDIR\test2.ini"

   Pop $9

     InstallOptions::show

FunctionEnd


>; --------------------------------------

!define CB_FINDSTRINGEXACT          0x0158

>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"

And these is my ini file

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.

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

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):

!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,)'

I got a idear to do it


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
