MmoPackMethod (Property)
The MmoPackMethod property sets the compression mode of a MMO file (containing text and binary memos) associated with a data file.
fSizeUncompressed (Function)
Returns the size of a file before compression. When a file is decompressed by fUncompress, we recommend that you to compare the non-compressed size of file with the available disk space.
zipSize (Function)
Returns the size of archive (in ZIP, RAR, CAB, WDZ or 7z format): the size of all compressed files found in the archive. the size of all files found in the archive before compression....
WDMap: Reindexing an HFSQL data file
WDMap is used to find out whether an HFSQL data file must be reindexed and reindex an HFSQL data file......
<zipArchive variable>.FileSize (Function)
Returns the size of one of the files found in the archive (in CAB, RAR, WDZ, ZIP, 7z, TAR or TGZ (TAR.GZ) format): the compressed size of the file. the size of file before compression....
Importing/Exporting a dictionary
WDTRAD allows you to import and export a dictionary......
zipFileSize (Function)
Returns the size of one of the files found in the archive (in CAB, RAR, WDZ, ZIP, 7z, TAR or TGZ (TAR.GZ) format): the compressed size of the file. the size of file before compression....
Compressing frames (DSL, 3G, Edge, VPN, ...)
A frame is a packet ot data that flows through the network......
Constants for encryption/compression
List of constants used by the encryption/compression functions...
Error 533: The expression of a { } must be a string
Error 404: The file for HFSQL browse cannot be an expression of this type
WDZip: Overview
WDZip is used to compress and group your files in archives......
Automatic features of edit controls
Edit controls provide multiple automatic features available in all the controls of your applications without writing a single line of code......
The archives
WINDEV, WEBDEV and WINDEV Mobile propose several WLanguage functions allowing you to compress and merge your files into archives......
LuhnCalculate (Function)
Calculates the next Luhn check digit for a given sequence.
LuhnCheck (Function)
Checks that the given sequence is valid according to the Luhn formula.
Uncompress (Function)
Decompresses a memory block (buffer) that was compressed by Compress.
Compress (Function)
Compresses a string or a memory block (buffer) in binary format.
<Buffer type>.EncryptAsymmetric (Function)
Encrypts a buffer using an asymmetric encryption algorithm (RSA) that requires a public key and a private key.
<Buffer type>.DecryptAsymmetricEnvelopped (Function)
Performs the asymmetric encryption of an envelope that has been encrypted with EncrypteAsymmetricEnveloped.
<Buffer type>.DecryptAsymmetric (Function)
Decrypts a buffer with a private/public key algorithm with RSA encryption....
EncryptGenerateRSAKey (Function)
Generates an RSA private/public key pair....
EncryptAsymmetric (Function)
