sComputeCrc16 (Function)

In french: sCalculeCrc16

Checks a character string before and after transmission between WINDEV applications and WEBDEVsites.

This function is used to check whether a character string was properly transmitted between WINDEV applications and WEBDEV websites during transmissions with risk of information loss (modem for example). To do this, simply calculate the "Crc16" before transmitting the chain, then check its value when the chain is received: the two values must be identical.

Example

nCrcLu is int	// Caractère de contrôle lu
LigneLue is string	// Chaîne lue
...
IF nCrcLu <> sComputeCrc16(LigneLue) THEN
	Info("Erreur lors de la récupération de la chaîne")
END

Syntax

<Result> = sComputeCrc16(<String>)

<Result>: Integer

Control value of the string.

<String>: Character string

Any character string.

Remarks

This function can return a different result in the WINDEV version. To improve the reusability to the code, we recommend that you use sComputeCrc32.
