HSimulateNetwork (Function)

In french: HSimuleRéseau

Available only with this kind of connection

Simulates the operating mode of HFSQL Client/Server on an ADSL or 3G network.

Remark: This function is used to test (in local or in LAN) an application that uses HFSQL in the conditions of an ADSL or 3G network. This function slows down all the communications between the client and the HFSQL server.
This function is used when debugging and optimizing an application. Remark: From version 19, HFSQL is the new name of HyperFileSQL.

Versions 21 and later

This function is now available in Universal Windows 10 App mode.

Example

// Simulate the 3G network
HSimulateNetwork(h3G)
ProfilerStart()
Proc_Process() // Process whose performance in 3G must be analyzed
ProfilerEnd()
// Back to a standard operating mode
HSimulateNetwork(hNone)

Syntax

<Result> = HSimulateNetwork([<Connection>, ] <Type of network>)

<Result>: Boolean

True if the simulation is started,
False if an error occurred.

<Connection>: Character string (with or without quotes) or Connection variable

Connection to use. This connection corresponds to:
the name of the connection defined in the data model editor or with HDescribeConnection or HOpenConnection.
the name of a Connection variable.
If this parameter is not specified, the simulation is applied to all the current and future connections.

<Type of network>: Integer constant

Type of network to simulate:
h3G Type of network to simulate: 3G
hADSL Type of network to simulate: ADSL
hNone Used to disable the simulation of a specific network.

Remarks

This function must not be used in a deployed application. This function is used when debugging and optimizing an application.
This function increases the latency and reduces the throughput of the network connections used for HFSQL Client/Server.
