I am working on something similar to a grid control, and I have nearly all the cell types that I want, except for one. I can't get the CComboBox to fit in 16 pixels vertically, mainly because I can't make it lose the client edge it draws. I've tried ModifyStyleEx(WS_EX_CLIENTEDGE, 0) with no luck. I've looked on www.codeproject.com and codeguru without much luck. I found a control that looked like it might do it, but it just draws over the client edge area with a window colored rectangle, so that screws with neighboring cells. surely people have encountered this problem before?
