listview subitem ‘s bkcolor

[netegg]

I've made out a listview with the checkbox in subitem, but i don't know why the subitem has a block grey color on the right side in the subitem, could anybody tell me?

It's the bizarre button you put there with _GuiCtrlButton_Create() inside the equally bizarre _initedit() function.

Why you put there is anybody's guess.

BTW, your WM_NOTIFY function crashes if you click on any column other than the first, because $Index = -1. See MSDN: NM_CLICK (List View) Notification:

Remarks

The iItem member of lParam is only valid if the icon or first-column label has been clicked. To determine which item is selected when a click takes place elsewhere in a row, send an LVM_SUBITEMHITTEST message.

Hi, thx. But how should I do? I've had no mind!

It looks like you copy/pasted this from somewhere else with no idea how any of it works. That makes it hard to figure out how much you need to know.

1. If you didn't need the button there for some reason, just delete it from the script.

2. Test $Index to see if it's < 0, and if so either ignore it (requiring the user to click either the first column or icon), or send LVM_SUBITEMHITTEST to find out which item it was. What matters is not using $Index when it's invalid, i.e. for $hButton[$Index].
