Hello all
I'm trying to add a checkbox to listview header which will select/unselect all checkboxes in the rows. I've wrote some code. But checkbox doesn't appear in the header.
WndProc code:
WndProc PROC hWnd:HWND, uMsg:UINT, wParam:WPARAM, lParam:LPARAM
LOCAL hdi :HDITEM
mov eax, uMsg
wp_wm_create:
cmp eax, WM_CREATE
jne wp_wm_destroy
push NULL
push hInstance
push NULL
push hWnd
push 500
push 400
push 10
push 10
push LVS_REPORT + WS_CHILD + WS_VISIBLE + WS_BORDER + LVS_SHOWSELALWAYS
push OFFSET szLVText
push OFFSET szLVClassName
push 0
call CreateWindowEx ;create listview control
mov hLV, eax
push LVS_EX_FULLROWSELECT + LVS_EX_CHECKBOXES + LVS_EX_GRIDLINES
push 0
push LVM_SETEXTENDEDLISTVIEWSTYLE
push eax
call SendMessage ;add full row select, gridlines and checkboxes to listview items
call InsertColumns ;add columns to listview
call InsertItems ;add rows to listview
push 0
push 0
push LVM_GETHEADER
push hLV
call SendMessage ;get handle of listview header
mov hLVHeader, eax
push GWL_STYLE
push eax
call GetWindowLong ;get header window styles
or eax, HDS_CHECKBOXES ;add to it checkbox style
push eax
push GWL_STYLE
push hLVHeader
call SetWindowLong ;set header window new styles(add checkboxes)
push 0
push SIZEOF HDITEM
lea eax, hdi
push eax
call memfill ;zero out HDITEM struct
mov hdi._mask, HDI_FORMAT ;get current format of listview header
lea eax, hdi
push eax
push 0
push HDM_GETITEM
push hLVHeader
call SendMessage
mov hdi._mask, HDI_FORMAT
or hdi.fmt, HDF_CHECKBOX
lea eax, hdi
push eax
push 0
push HDM_SETITEM
push hLVHeader
call SendMessage ;add checkbox to header format
jmp exit_zero_WndProc
wp_wm_destroy:
cmp eax, WM_DESTROY
jne wp_wm_none
push 0
call PostQuitMessage
jmp exit_zero_WndProc
wp_wm_none:
push lParam
push wParam
push uMsg
push hWnd
call DefWindowProc
jmp exit_nonzero_WndProc
exit_zero_WndProc:
xor eax, eax
exit_nonzero_WndProc:
ret
WndProc ENDP
I'll add whole code if needed.
Could someone point me what is wrong?

it's in C++ or whatever
but, you can see they used extended style LVS_EX_CHECKBOXES or LVS_EX_FULLROWSELECT
and - that common controls 6.0 or later is required
so - you need a manifest and InitCommonControls (probably Ex) if using XP

It's Delphi - probably objective Pascal. I don't know it.

I've also added those extended styles to my listview.
I'm using Win7. So checkbox in listview header should work.

You mean manifest file? I don't how to write it.
I've searched a lot about this issue before i've posted here and i've found some interessting sites.
c++ MFC:
http://www.codeproject.com/Articles/157033/How-to-Add-a-Checkbox-to-a-List-View-Column-Header

(http://www.codeproject.com/Articles/13586/Using-Check-Box-in-List-Control)
But can't compile it on my VS. And I have pure c/c++ basic skills.
it's pretty easy to add a manifest for common controls 6.0
here is the text in the manifest file
it is XML - i usually name the file like ProjectName.xml
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<dependency>
<dependentAssembly>
<assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="*" publicKeyToken="6595b64144ccf1df"/>
</dependentAssembly>
</dependency>
</assembly>
then, you add that to the resource file
the manifest for EXE's uses 2 constants
some older versions of resource.h did not have these constants defined
the newer versions do
so, i add them like this
#include "\masm32\include\resource.h"
#ifndef CREATEPROCESS_MANIFEST_RESOURCE_ID
#define CREATEPROCESS_MANIFEST_RESOURCE_ID 1
#endif
#ifndef RT_MANIFEST
#define RT_MANIFEST 24
#endif
then, to add the manifest....
CREATEPROCESS_MANIFEST_RESOURCE_ID RT_MANIFEST "ProjectName.xml"
some members don't want to go through all that
they just use
1 24 "ProjectName.xml"
essentially the same thing
now, in your program...
.DATA
icc INITCOMMONCONTROLSEX <sizeof INITCOMMONCONTROLSEX,0>
.CODE
Start: INVOKE InitCommonControlsEx,offset icc
notice that the 0 in the structure may be replaced by whatever flagset you desire

looks like you'd want at least ICC_LISTVIEW_CLASSES
or you might use ICC_WIN95_CLASSES, which incudes that flag
Great thanks dedndave. Checkbox is now on the header. But it doesn't mark item checkboxes. I'll try to figure out how to do it. Anyway once again great thanks :greenclp:.
