How disable a checkbox in ListView

Hi. Tell me please. Whether it is possible to block one of the elements of the ListView? By type: "EnableWindow $var 0".

I'm not sure if you can disable a item checkbox without a custom imagelist.

If you really want to go down this path you have to create your own state imagelist and draw the checkboxes with DrawFrameControl. This is more code than I feel like writing right now and is hard to get right because you have to deal with Visual Styles etc.

If you run control inetcpl.cpl,,6 for example they are using (a TreeView in that case) with a custom state image list. You can see the image if you open inetcpl.cpl with Resource Hacker. They are probably loading it with a custom version of LoadImage(...,LR_LOADTRANSPARENT|LR_LOADMAP3DCOLORS). On Windows 8 this happens in IEFRAME!CRegTreeOptions::InitTree -> IEFRAME!CRegTreeOptions::_CreateImageList (It tries OpenTheme(0,L"Button")+GetThemePartSize+DrawThemeBackground first)

Windows 2000 uses the "flat fat" style from DrawFrameControl: https://wayback.archive.org/web/2016.../screen_02.gif

Windows XP uses DrawThemeBackground: https://wayback.archive.org/web/2016.../c00741753.gif
