Speeding up the importing of data from file
I am using the following to import binary data from a file and convert
to hexadecimal. Is there a different way to do this that would be faster? I got list help last year to speed up my checksum routine by putting the data into a variant. I was able to also us it for saving to a file too. I need some of the same magic importing file data. File size can be over a meg in size and is taking minutes to load. __________________________________________________ ___ Dim fs, f, ts, s Set fs = CreateObject("Scripting.FileSystemObject") Set f = fs.GetFile(FileNameWithPath) Set ts = f.OpenAsTextStream(ForReading, TristateUseDefault) ColumnCount = 3 RowCount = 1 Do While ts.atendofstream = False 'Loop to fill column with HEX numbers DecimalByte = Asc(ts.Read(1)) HexByte = Hex(DecimalByte) Cells(RowCount, ColumnCount) = HexByte RowCount = RowCount + 1 Loop ts.Close |
