This is as short as I can produce it.
This sample is showing a standard created button using CreateWindow added with Visual Style, the button has an ugly white border (properly the standard background brush)
and then a subclassed static control also created with CreateWindows and then used SetWindowLong and added Visual style using a button template, this has not the ugly white border, its showing how it should be.
Is it really neccessary to subclass each and every control to remove the ugly white border?
And how about an app wide Font that will be added as default font for each and every control or text that will be output?
