GET PICTURE FROM LIBRARY


GET PICTURE FROM LIBRARY ( picRef \| picName ; picture )

Parameter	Type	Description
picRef \| picName	Longint, String	Reference number of Picture Library graphic or Name of Picture Library graphic

Description

The GET PICTURE FROM LIBRARY command returns in the picture parameter the Picture Library graphic whose reference number is passed in picRef or whose name is passed in picName.

If there is no picture with that reference number or name, GET PICTURE FROM LIBRARY leaves picture unchanged.

Example 1

The following example returns in vgMyPicture the picture whose reference number is stored in the local variable $vlPicRef:

GET PICTURE FROM LIBRARY($vlPicRef;vgMyPicture)

Example 2

The following example returns in $DDcom_Prot_MyPicture the picture with the name "DDcom_Prot_Button1" stored in the Picture Library:

GET PICTURE FROM LIBRARY("DDcom_Prot_Button1";$DDcom_Prot_MyPicture)

Example 3

See the third example for the command PICTURE LIBRARY LIST.

System variables and sets

If the Picture Library exists, the OK variable is set to 1. Otherwise, OK is set to zero.

Error management

If there is not enough memory to return the picture, an error -108 is generated. You can catch this error using an error-handling method.
