InvokePBFunction

PowerScript function

Description

Invokes the specified user-defined window function in the child
window contained in a PowerBuilder window ActiveX control.

Applies to

Window ActiveX controls

Syntax

1	activexcontrol.InvokePBFunction ( name {, numarguments {, arguments } })

Argument	Description
activexcontrol	Identifier for the instance of the PowerBuilder Window ActiveX control. When used in HTML, this is the NAME attribute of the object element. When used in other environments, this references the control that contains the PowerBuilder window ActiveX.
name	String specifying the name of the user-defined window function. This argument is passed by reference.
numarguments (optional)	Integer specifying the number of elements in the arguments array. The default is zero.
arguments (optional)	Variant array containing function arguments. In PowerBuilder, Variant maps to the Any datatype. This argument is passed by reference. If you specify this argument, you must also specify numarguments. If you do not specify this argument and the function contains arguments, populate the argument list by calling the SetArgElement function once for each argument. JavaScript cannot use this argument.

Return value

Integer.

Returns 1 if the function succeeds and -1 if an error occurs.

Usage

Call this function to invoke a user-defined window function in the
child window contained in a PowerBuilder window ActiveX control.

To check the PowerBuilder function’s return value, call the
GetLastReturn function.

JavaScript cannot use the arguments argument.

Examples

This JavaScript example calls the InvokePBFunction function:

function invokeFunc(f) {

var retcd;

var rc;

var numargs;

var theFunc;

var theArg;

retcd = 0;

numargs = 1;

theArg = f.textToPB.value;

PBRX1.SetArgElement(1, theArg);

theFunc = "of_args";

retcd = PBRX1.InvokePBFunction(theFunc, numargs);

rc = parseInt(PBRX1.GetLastReturn());

IF (rc != 1) {

alert("Error. Empty string.");

}

PBRX1.ResetArgElements();

}

This VBScript example calls the InvokePBFunction function:

Sub invokeFunction_OnClick()

Dim retcd

Dim myForm

Dim args(1)

Dim rc

Dim numargs

Dim theFunc

Dim rcfromfunc

retcd = 0

numargs = 1

rc = 0

theFunc = "of_args"

Set myForm = Document.buttonForm

args(0) = buttonForm.textToPB.value

retcd = PBRX1.InvokePBFunction(theFunc, &

numargs, args)

rc = PBRX1.GetLastReturn()

IF rc <> 1 THEN

msgbox "Error. Empty string."

END IF

PBRX1.ResetArgElements()

END sub
