Stored procedures
Starts an FTP server (File Transfer Protocol) or an RPC server (Remote Procedure Call) powered by WINDEV.
ConnectRPC is int
// Connects to an RPC server on port 5010
ConnectRPC = NetStartServer(RPCServer, False, 5010)
<Result> = NetStartServer(<Server> [, <Encryption> [, <Port number> [, <Key> [, <Server IP address>]]]])
<Result>: Integer
  • Identifier of the server,
  • 0 if the connection failed.
<Server>: Constant
Type of server:
FTPServerA WINDEV FTP server is used. The functions for file management are allowed (NetSendFile and NetGetFile for example).
RPCServerA WINDEV RPC server is used.
<Encryption>: Optional boolean
  • True to encrypt the transmitted data,
  • False (default value) for no encryption.
If the server is started with the encryption option set to True, the client computers must connect with NetConnect by using <Encryption> = True.
If an encryption is requested, the connection key (<Key>) will also be encrypted.
<Port number>: Optional integer
Number of the port on which the server will be run. By default, the client tries to connect to the server:
  • on port 2000 for WINDEV RPC.
  • on port 2001 for WINDEV FTP.
To create a custom RPC server on HFSQL, use port 5001. For more details, see "WINDEV RPC server for a remote access to an HFSQL database" (below).
<Key>: Optional character string
Used to secure the access to the server. Each client trying to connect to the server must use the same key as the one defined by NetStartServer. The connection is refused if the keys are different.
If the <Encryption> parameter is set to True, the key is encrypted.
<Server IP address>: Optional character string
Server IP address. This parameter must be specified if the server has several IP addresses (server using several network cards for example). This IP address can have the following format:
  • IP address in XXX.XXX.XXX.XXX format ( for example).
  • IP address containing the server name (pop3.freesbee.eu for example). This syntax is recommended.
  • IP address returned by NetIPAddress.

Server parameters

The server parameters are required before a connection is established:
  • If the port number is specified, the client will have to use the same port number in NetConnect.
  • If the server is started with <Encryption> set to True, the clients must connect with <Encryption> set to True in NetConnect.
  • If the server is started with a specific <Key>, the clients must connect by specifying the same <Key> in NetConnect.

User name and password

The <UserName> and <Password> parameters allow the server to check whether the user is authorized or not. The list of authorizations and passwords for the users is available in the WDRPCSRV.INI file found in the directory of the server project. Example of file content:

WINDEV RPC server for a remote access to an HFSQL database

A RPC server used to access an HFSQL database is available in the program directory of WINDEV (WDRemoteAccessServer.EXE). For more details, see Remote access to an HFSQL database.
During a remote access to an HFSQL database, the data is accessible via a WINDEV RPC server program. This program must use:
  • NetStartServer to start the RPC server.
  • NetEndServer to stop this server.
Remark: By default, the RPC server is using port 5001. Furthermore, the WINDEV RPC server requires:
  • the wdxxxcom.dll library in order to use the communication functions of WINDEV
  • the wdxxxhf.dll library in order to access the functions for HFSQL management
  • the description file of the analysis (".WDD" file) in order to access the relevant database
  • the WdRpcsrv.ini file that contains the connection rights granted to the users. This is a text file that is found in the same directory as the RPC server. It must contain a "password" section in which each entry point is a username:
  • a specific section in the "Win.ini" file. This section must have the same name as the description file of the analysis. It contains entry points used to locate the data files and the description file of the analysis.
    REM Directory of the files defined in the analysis
    REM in the program directory (<?>)
    REM Full name of the description file
    REM of the analysis (.wdd)
    REM Equivalent to SubtDir, for the files whose
    REM the directory is specified

    Remark: The lines starting with "REM" are comments and they are useless.
Remark: From version 19, HFSQL is the new name of HyperFileSQL.
