MyData()) Notes: It must be a byte array. To to this, pass the array name and both parentheses as per ( ), with no number inside of them. This passes a reference to the entire array. When this method is successful, the CompressedSize property contains the compressed size of the data, the OriginalSize property contains the original size of the data before compression. Returns: Error code. If 0 then it was successful. If negative, then an error has occurred. method DecompressData Usage: Decompresses a byte array, given the original size Parameters: Byte Array, (ie. MyData()), Long (ie, OrigSize&) Notes: The byte array is the compressed data, the Long represents the original (decompressed) size of the data. You can retrieve this original size from the property OriginalSize after calling a successful CompressData method. The OriginalSize and CompressedSize properties are reset to zero. Returns: Error code. If 0 then it was successful. If negative, then an error has occurred. method CompressString This method is the same as the CompressData method and produces the same results, but the first parameter is a string, not a byte array. The CompressedSize and the OriginalSize properties are filled with the same values as per the CompressData method. method DecompressString This method is the same as the DecompressData method, only that the first parameter is a string, not a byte array. The CompressedSize and OriginalSize properties are reset to zero. property CompressedSize Read-Only.
