ReadFile Waldermort4-Sep-07 0:32 Waldermort 4-Sep-07 0:32  Using the ReadFile() api, how would one determine if the bytes being read are ASCII, MBCS, UNICODE or even UTF8? Re: ReadFile Naveen4-Sep-07 1:44 Naveen 4-Sep-07 1:44  Actually the first few bytes of files is used to identify the type of encoding. For example for plain ascill there will not be any speciall bytes. For UNICODE - FF FE For UTF-8 - EF BB BF nave [OpenedFileFinder] Re: ReadFile Nishad S4-Sep-07 2:18 Nishad S 4-Sep-07 2:18  It is only for .txt files only. Am I right? - NS - Re: ReadFile Naveen4-Sep-07 2:23 Naveen 4-Sep-07 2:23  May be. But all other file formats( having text data ) are applications specific such as doc or xls. So its there own implementation. nave [OpenedFileFinder] Re: ReadFile Waldermort4-Sep-07 3:09 Waldermort 4-Sep-07 3:09  This won't work in my situation since I'm not actually reading a file but a pipe. I'm diverting the putput of a console, so the bytes being read could either be ascii or unicode, but I have yet to find an easy way to determine which. Why there would be a single line left on the screen when the dialog disapear? kcynic4-Sep-07 0:28 kcynic 4-Sep-07 0:28  I have a owner-draw dialog,I change its default color to blue.But when the dialog was minimized,there would be a thin rectange left on the screen. Someone would like to tell me why and how to resolve it? Thanks. GOOD LUCK Re: Why there would be a single line left on the screen when the dialog disapear? Mark Salsbery4-Sep-07 5:45 Mark Salsbery 4-Sep-07 5:45  What do you mean by "owner-draw dialog"?

Then,when the dialog is minimized,there would be a thin frame on the screen! Re: Why there would be a single line left on the screen when the dialog disapear? Mark Salsbery5-Sep-07 5:01 Mark Salsbery 5-Sep-07 5:01  Are you setting a proper window region for the shape of the window?

When I paint the window,I used GetClientRect() function. I neglected the fram width! Thanks very much. GOOD LUCK.
