Custom Query

Hi.

I use background picture for some app. But, some control are not pretty because I can not set the transparency background.

Can you implement for other control the

GUICtrlSetBkColor(-1, $GUI_BKCOLOR_TRANSPARENT)

Like GUICtrlCreateGroup label, GUICtrlCreateCheckbox label, ...

GUICtrlCreateLabel is OK.

Thanks

If you boot your OS with LAN cable unplugged and use ping function

$result = Ping("8.8.8.8", 1000)
MsgBox(262144,'Result','Return Value is: ' & $result & @lf & @lf & '@error code is: ' & @error )

return value will be 1 and @error will be 0 but corect return value should be 0 and @error should be 4 (or 1). I think this is not correct.

I duplicated this issue under Windows 7, WinPE 3.0, WinPE 4.0

I'd love to see the code below included as an easily usable extended style for listview controls. In a listview with several subitems, keeping the entire row highlighted if the item is checked ($EX_LVS_CHECKBOXES) makes it very easy to quickly scan values in subitem columns.

The example below from user 'rasim' does not use the built-in listview extended style checkboxes, but I would prefer that it did.

Being able to add this functionality as an extended style, without having to delve into WinAPI/GDIPlus would be a huge time saver. Also having the style work with WM_NOTIFY '$NM_CLICK' anywhere on the row (vs just the checkbox itself) would be perfect.
