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
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()
