  1. PODelphi Pascal - how to write data to file larger than 2 GB?
    text
    copied!<p>I made a tool in Delphi to create rainbow table. It was fine until file grew up to 3.1 GB. I closed my program. Then i opened it again and it crashes while executing this code:</p> <pre><code>Assign(RainbowFile,'Rainbow_table.txt'); {assign a text file} Append(RainbowFile); </code></pre> <p>Delphi shows error "raised expection class EInOutError with message 'I/O error 131'. My question: how to append data to existing file bigger than 2 GB. // Obsolete Next question: I have currently code:</p> <pre><code> Content_to_file := (#13+#10+Start_string+':'+hexstr(GTA_San_Andreas_CRC32(Start_string), 8)); RainbowFile_handle.WriteBuffer( Content_to_file[1], Length(Content_to_file)*SizeOf(Char)); </code></pre> <p>How to get rid of Content_to_file variable. I want put it directly to the WriteBuffer if it`s possible. </p> <p>EDIT:</p> <p>TFileStream works with files bigger than 2 GB. I tested it now. However is it possible to write so:</p> <pre><code>RainbowFile_handle.WriteBuffer( Start_string[1]+':', </code></pre> <p>I mean to pass no variable argument. Or do i have definitely pass first char of variable?</p> <p>EDIT 2:</p> <p>I have currently made it this way:</p> <pre><code> Content_to_file := (#13+#10+Start_string+':'+hexstr(GTA_San_Andreas_CRC32(Start_string), 8)); RainbowFile_handle.WriteBuffer( Content_to_file[1], Length(Content_to_file)*SizeOf(Char)); </code></pre> <p>Is it possible to do it without this variable?</p>
