Statement has a problem, instead of the following statement, I use in the project, there is no problem is//compression
The Function Long compress (Ref Blob compr, Ref Long comprLen, Ref Blob buf, Long buflen) Library "zlibwapi. DLL" alias for "compress; Ansi
"//unzip
The Function Long uncompress (Ref Blob uncompr, Ref Long uncomprLen, Ref Blob compr, Long lcomp) Library "zlibwapi. DLL" alias for "uncompress; Ansi"

Thank you moderator! Revised statement, or the same mistake, and zlibwapi. DLL version and the position of the matter?CodePudding user response:
The zlibwapi. DLL file into the system32 directory, is no longer an error, but is compressed and the length of the data before compression, len (bl_data_zip), found that the compressed data length is about 2 times before compression, the compression, the greater the don't understand, also give advice or comments please moderators!CodePudding user response:
