Frequently Asked Questions
Database & Security System
Q. What does the Shared Tags folder store
A. The Shared Tags folder stores the tags imported from the PC-based Control linked to the IWS project. The
PC-based Control is linked to the project by the New Project wizard.
Q. How do I count how many tags are configured in the project database
A. The number of tags currently used in the project is displayed in the status bar at the bottom of the
development environment. Each array position and each class member of the tags configured in the IWS tag
database are counted.
Q. How do I see the list of "Users" I've added during runtime in my project that I have created with the
CreateUser() function
A. Execute the following command: "Studio Path\BIN\Studio Manager.exe" "Studio Path\BIN
\ExtUser.dll" (for example: "E:\Program Files\Studio\BIN\Studio Manager.exe" "E:\Program
Files\Studio\BIN\ExtUser.dll" ). This command will launch a dialog. You can see the users created by
the CreateUser() function, and you can then create or delete users.

Q. How do I insert and configure an ActiveX object in a project
A. To insert an ActiveX object in a project screen:
1. On the Graphics tab of the ribbon, in the Libraries group, click ActiveX Control.
2. Select the ActiveX control that you want to insert from the list, and then click OK. The ActiveX object will
then appear on the screen. (Unregistered ActiveX objects will not be available in this list box.)
3. Double-click on the ActiveX object and assign a name to it (enter a value in the Name field). The animations
and methods list can be viewed by selecting the Methods button. The static properties can be set by the
Properties button (A detailed description about the objects properties can be found in the component
documentation, provided by the component developer).
There are three functions to access the ActiveX component during runtime:
• XGet(strName,strProperties): Returns the value of the properties strProperties from the object
strName. The list of properties which can be read from the object are listed in the Object Properties dialog
from the object, with the syntax Properties Name(PropGet) (for example, Color(PropGet) ).
• XSet(strName,strProperties,Value): Writes the value Value to the properties strProperties of
the object strName. The list of properties which can be set to the object are listed in the Object Properties
dialog from the object, with the syntax Properties Name(PropPut) (for example, Color(PropPut) ).
• XRun(strName, strMethod, Parameter1, Parameter2, …, ParameterN): Executes the method
strMethod from the object strName, according to the parameters Parameter1, Parameter2, …,
ParameterN. The list of methods available in the object is listed in the Object Properties dialog from the
object, with the syntax Method Name(Method) (for example, OpenFile(Method) ).
Tip: Before inserting an ActiveX control (usually an OCX file) into the project, make sure it has
been properly registered in the computer. To register an ActiveX control from with the development
application, click Register Controls on the Home tab of the ribbon.
Note: The amount of parameters set in the XRun() function can vary from 0 up to 255 and it
depends each the ActiveX component. It's possible to use tags to set the parameters; however, the
tag type must match the component parameter type (Boolean, integer, string or real).
Q. How do I designate one screen that will open each time I start the project
A. On the Project tab of the ribbon, in the Settings group, click Viewer, and then in the Project Settings dialog,
type the startup screen name in the Startup screen box.
