(upload.htm): The file object is used in the program, so the raw data that is read by the BinaryRead method in the upload.asp is not only the data of the selected file itself, but also the description of the path, type, the form domain name of the file on the user's hard disk, and the related information. So we need to extract the specific contents of the file. According to the analysis, the data's header information and the data dividing line is two pairs of carriage return line character, t

(10) can return line breaks. The normal charcode range is 0-255. However, in the DBCS system, the actual charcode range is-32768 to 65535. Note: The chrb function acts on the byte data contained in the string. Chrb always returns a single byte instead of a single character. A character may be one or two bytes. The chrw function returns a string that contains Unicode. If Unicode is not supported, the functi

The answer is in the negative.

ASC and AscB, AscW The ASC function returns the ANSI character code corresponding to the first letter of the string. ASC (String) The AscB function is used in conjunction with a string containing byte data. Instead of returning the character code for the first character, AscB returns the first byte. The ASCW is provided for 32-bit platforms that use Unicode characters. It returns the Unicode (wide) character code, so you can avoid code conversions from ANSI to Unicode. Chr and
