how can i set an icon of window to a .ico file?
-
As far as I know SFML does not support ICO files.
But you can use a PNG.
-
sf::Window::setIcon() (http://www.sfml-dev.org/documentation/2.3.1/classsf_1_1Window.php#a63af61e026fba08e3153fd013620bcc0) takes a pointer to an array of pixels (in a specific order). An sf::Image stores its data in an array of pixels (in that required order) and can return a pointer to them.
Therefore, any of sf::Image's file formats can be used to set the window's icon.
From sf::Image::loadFromFile() (http://www.sfml-dev.org/documentation/2.3.1/classsf_1_1Image.php#a9e4f2aa8e36d0cabde5ed5a4ef80290b):
The supported image formats are bmp, png, tga, jpg, gif, psd, hdr and pic.

well then, is it possible to set it from resource then?

It depends on your definition of the word resource. If you mean a resource such as a file (you can use the method above) or an sf::Texture (you can use loadFromImage in combination with the above method). However, if you mean Windows' definition of resource (e.g. a script linking external resources), you'll be using Windows-specific code (becomes non-cross-platform).
If you are looking for to only Windows-specific, you should look at this (https://msdn.microsoft.com/en-us/library/windows/desktop/ms648045%28v=vs.85%29.aspx) or that (https://msdn.microsoft.com/en-us/library/windows/desktop/ms648072%28v=vs.85%29.aspx). SFML can give you the window's handle (HWND) using sf::Window::getSystemHandle() (http://www.sfml-dev.org/documentation/2.3.1/classsf_1_1Window.php#a26368e7162229f8637c34d80ab0f138e).
This (http://www.cplusplus.com/forum/general/28470/) may also be of help (still Windows-specific).

You can also embed the pixel data using a const uint8[] right in your code, which is essentially like your resource, but cross-platform (although a bit tricky to update).
