Which IDE and version of VA are you using? Are you simply seeing a listbox when you type "TCHAR" or is "TCHAR" actually being turned into "char" when you type it?
When I Created an APP based UNICODE, all the functions, marco are Suggest to ANSI Edition by VA.
For example, when I put my mouse on "TCHAR", VA doesn't show it to be type "wchar_t" but "char" when I put my mouse on "MessageBox", VA doesn't show it to be function "MessageBoxW" but "MessageBoxA"
When you put the mouse over TCHAR what are you looking at? A tooltip caused by hovering the mouse? Are you looking at the VA context and definition fields? Something else?
I do not understand what you are doing, or what you are seeing.
