Readfile command to read binary file error!

[youtao6256]

I would like to use readfile (, "b", 20, 25) command to read the wav file 25,26 bytes of hexadecimal data, but found that the command read the hexadecimal data and source files of the ten Hexadecimal data is not the same? The source file data is 0xAC44, but the incoming data bits 0x3F44, using the pattern “b” or “t” are not correct.

Source file hexadecimal,the wav file 25,26 bytes of hexadecimal data is 0xAC44

1) Do you see the correct values when you view the file with command File | Quick File View (Ctrl+Q)?

I know that this bug related to the system area, when the system format is set to Chinese, read the data wrong, set the format for the United States is correct, I am a Chinese user, hoping to solve this problem.

Hi, I have been updated to 18.20.0300 But how does the readfile command read errors?

script：text hexdump (readfile(, "b",50, ,1),,"b"),1,);

Look at the location of 18h, 0xAC44 or become 0x3F44

You should use the new "r" mode (r = raw bytes, binary safe, no conversion):

Code: Select all

text hexdump(readfile( , "r", 50), , "b");  //you see the true bytes

Thank you very much for your help, this is indeed the case, I hope you can update the script command help, there are only "t" and "b" mode.

But I used the writefile command encountered problems, trouble to help me see where I use the wrong!

script：writefile("test-out.txt", readfile(, "r"),,"r");
File size and data are problematic!

You are right, the fix was not complete. Next version should have it all. Then you can do either of these:

Code: Select all

writefile("test-out.txt", readfile(, "r"), , "r");

Code: Select all

writefile("test-out.txt", readfile(, "ru"), , "ru");

The help file us updated with each bigger release.
