Hi, <br>I developt a serial communication program.It works under Windows 2000 perfectly. I used CEditView class for terminal window. But when i compile this program under Windows98 i can't see any received characters on CEditView. when I use CListBox for terminal window i see received chars from the UART. <br>The CEditView is working different under Windows 98/200. if It is ok, what are the differents. else where should problem be?. <br><br>Best Regards from Turkey.<br><A HREF=" TARGET="_new">
