Description
Object Type of ScreenItem Object. Represents the graphic object "Button"
Type Identifier in VBS
HMIButton
Usage
In the following example, the object with the name "Button1" is moved 10 pixels to the right:

Notes on Error Handling
Buttons and pushbuttons are mapped in the object model to an "HMIButton" type. Since the
objects have different properties, the availability of the property (dynamic type compilation in

Runtime) should be queried via an exception measure. The exception measure is activated
for the corresponding procedure by the following instruction:
On Error Resume Next
The instruction causes the VBScript engine to initiate the follow-on command in the case of a
Runtime error.
The error code can subsequently be checked using the Err object. In order to deactivate the
handling of Runtime errors in scripts, use the following command:
On Error Goto 0
Handling errors always relates to the procedure layer. If a script in a procedure causes an
error,
VBScript checks whether an error handling measure is implemented in this layer. If not,
control is transferred one layer up (to the calling procedure). If there is no error handling
measure here either, the control is transferred yet another layer up. This continues until either
the top module level is reached or the code for Runtime error handling is located. If the
activation of the Runtime error handling fails, the control is transferred to the top level on the
internal VBScript Runtime error handing. This opens an error dialog and stops the script.
The "On Error Resume Next" command can be installed on all layers (i.e. also in procedures).
When the error handling measure is use, it can basically be determined whether the user is
actually using the required implementation type.
In addition, it can be ensured that there is no termination of execution due to a faulty access
to the object.
Examples of error handling
Sub OnClick(ByVal Item)
'VBS48
Dim objScreenItem
On Error Resume Next 'Activation of errorhandling
For Each objScreenItem In ScreenItems
If objScreenItem.Type = "HMIButton" Then
'
'=== Property "Text" available only for Standard-Button
objScreenItem.Text = "Windows"
If 0 <> Err.Number Then
HMIRuntime.Trace objScreenItem.ObjectName & ": no Windows-Button" & vbCrLf
Err.Clear 'Delete error message
End If
End If
Next
On Error Goto 0 'Deactivation of errorhandling
End Sub
