DDESend (Function)

In french: DDEEnvoie

Sends a data to the program connected via DDE.

Example

MaConnexion = DDEConnect("Excel", Sujet)  // Connexion
Compteur = 3	  // Répète 3 fois si nécessaire
LOOP	   // Envoie les données
	IF DDESend(MaConnexion, Item, Data, 10) = True THEN BREAK
	Compteur --
	IF Compteur = 0 THEN
		Error("L'information n'a pas pu être envoyée à Excel")
		BREAK
	END
END
DDEDisconnect(MaConnexion)	// Déconnexion

Syntax

<Result> = DDESend(<Connection ID> , <Object for Sending> , <Data> [, <Timeout>])

<Result>: Boolean

True if the sending was performed,
False if an error occurred (DDEError returns the details of the error).

<Connection ID>: Integer

Connection identifier, returned by DDEConnect.

<Object for Sending>: Character string

Object for sending to the program.

<Data>: Character string

Data that must be sent to the connected program.

<Timeout>: Optional integer or optional Duration

Maximum wait duration (in seconds). If the command was not run:
If <Timeout> is specified, there is a delay of <Timeout> seconds before exiting DDESend.
If <Timeout> is not specified, there is an endless wait.
Note: This parameter can correspond to:
an integer corresponding to the number of seconds,
a Duration variable,
duration in plain text (e.g. '1s').

Remarks

Limit

The size of the parameters used by DDESend is limited to 1000 characters.

External languages

When using external languages in WINDEV, "Send" should be used instead of DDESend. All the parameters must be specified. The syntax is as follows:

in C: APPELDDE("Send,Recipient,subject,info")
in Turbo Pascal Windows: APPELDDE('Send,Recipient,subject, info')
in Visual Basic Windows: call APPELDDE("Send,Recipient,subject, info")

A maximum number of characters is allowed for each parameter:

Recipient: 8 characters
Subject: 30 characters
Info: 100 characters
