A function to add the unicode description string in the status bar of the charmap of ReactOS. Ready for comments and suggestions.

charmap1func.c

void UpdateStatusBar(WORD wch) // The function gets a Unicode value
{
LPWSTR szCharDesc;
GetUName(wch,szCharDesc); //Gets the Character's Description String
WCHAR buff[sizeof szCharDesc + 30];
wcscpy(buff,"U+%X: %s", wch, szCharDesc); //Putting it in a nice string
SendMessage(hStatusWnd,WM_SETTEXT,SB_SIMPLE,(LPARAM)buff); // push it to the status bar
}
