Hungarian notation can be used. I don't bother myself, but I give various things (variables, controls, etc.) sensible names.
For example, I use a Hungarian-style prefix for control names such as txt for TextBoxes, btn for Buttons, pic for PictureBoxes, lbl for Labels, etc. That helps to easily identify what a control is.
For function names I try and use sensible explanatory names, but nothing with any particular rules. For variable names again I just use explanatory names but nothing special.
