I've been using CColor() (see below) to color controls for years, back with basic and in at least one other script in _L but it was with the ansi build... Now i'm trying to use it in the Unicode build (32-bit or 64-bit) and I get weird effects:

Code: Select all
/*
Function: CColor
Set text and background color for some Gui controls.
Supported types: Edit, Text, ListBox, ComboBox, DropDownList, CheckBox, RadioButton, ListView, TreeView, RichEdit
Parameters:
Hwnd - Handle of the control.
Background - Background color. HTML color name or 6-digit RGB value. Optional.
Foreground - Foreground color. HTML color name or 6-digit RGB value. Optional.
Remarks:
You need to redraw the window for changes to take effect. For some controls, it may be needed to explicitelly specify
foreground color ("cRed") when creating control, otherwise text will stay black.
On tha first call for a specific control class the function registers itself as message handler for WM_CTLCOLOR
message of appropriate class.
Buttons are always drawn with the default system colors. Drawing buttons requires several different brushes-face, highlight and shadow
but the WM_CTLCOLORBTN message allows only one brush to be returned. To provide a custom appearance for push buttons, use an owner-drawn button.
