Message (Function)

In french: Message

Displays or removes a message from the status bar of the current window or browser.

Remark: The window or browser window must have a status Bar.

If the status bar is divided into several cells, you have the ability to specify the cell where the message is displayed.

To easily share code between the WINDEV and WEBDEV applications, this function has no effect in server code.

Example

Message("Processing...")
MyProcess() // Procedure used to perform the requested process
Message("Ready")

// Message in the "MCB_Info" cell
Message(MCB_Info, "Enter your name")

// Message with scroll
Message("Welcome!", Scrolling, 5)
