How to change title bar color in windows style panel

[Wolfgang · Accepted solution]

ATTR_TITLE_BACKCOLOR is a panel attribute, not a control attribute, so you need to call SetPanelAttribute (g_hchild1, ATTR_TITLE_BACKCOLOR, VAL_DK_GRAY), not SetCtrlAttribute (...)

For this to work you also need to set the Title bar style to 'classic'

'Classic' style is not really the look I'm going for but the 'SetPanelAttribute' call was the overall solution to change the title bar color.

Thanks to all for there help.
