| The following reads from a file and outputs the contents to the console. [codebox] file=OpenFile("race.bmx") If Not file RuntimeError "could not open file openfile.bmx" While Not KeyHit(Key_escape) Cls While Not Eof(file) print ReadLine(file) Wend [codebox] I however want to output the contents the a display using drawtext.I can't use drawtext readline(file),x,y.I need to store the contents of the file in a type but what type? Will a string type hold eofs and multiple lines ? Thanks in advance |

| It's possible to read an entire file as a single string with "Text$ = ReadString( InFile, StreamSize( InFile ) )" and Print would output it correctly including tabs and returns, but DrawText won't. This has no wrapping or scrolling for large lines/files, but shows the approach that I'd use: Strict Local Filename$ = "race.bmx" Local InFile:TStream = ReadFile( Filename ) If InFile = Null Then RuntimeError "Could not open file " + Filename Graphics 1024, 768 Local Text$, TextY While Not Eof( InFile ) Text = ReadLine( InFile ) Text = Replace( Text, Chr(9), " " ) 'replace tabs with 2 spaces DrawText Text, 0, TextY TextY :+ TextHeight( Text ) Wend Flip CloseFile( InFile ) FlushMem WaitKey |
