chrb

the delimiter plays an important role in splitting multiple data segments (including text boxes and various types of files. As analyzed earlier, the delimiter appears before the first carriage return line break. Therefore, you can use the following program to obtain the delimiter code: Newline = chrb (13) chrb (10) 'newline indicates the binary carriage return. Filesize = request. totalbytes 'filesize is

separator, but the text box and file forms slightly different, this can be analyzed by a specific binary code to understand. 3, using ASP technology to achieve file storage Handling of uploading file code 1) Get the separator code From the above analysis, we already know that a separator plays an important role in segmenting multiple data segments, including text boxes and various types of files. As previously analyzed, the separator appears before the first carriage return line symbol. Ther

As previously analyzed, the separator appears before the first carriage return newline symbol. Therefore, the following procedure allows you to obtain the delimiter code:NEWLINE=CHRB (
