Remarks

Running the Expand/Collapse process

For a TreeView control
The "Collapse/Expand" process of a treeview available in the code editor expects the two following parameters:

<Element path>: Text variable containing the full path of the element currently collapsed or expanded. All you have to do is specify the name of a variable, this variable will be automatically initialized at run time.
<Collapsed>: Boolean variable, used to find out the action performed by the user (collapse = True, expand = False). All you have to do is specify the name of a variable, this variable will be automatically initialized at run time.

These two parameters must be specified when this process is run by ExecuteProcess. In this case, the following syntax must be used:

ExecuteProcess(<Name of TreeView Control>, trtCollapseExpandBranch, ...
<Element path>, <Collapsed>)

See WLanguage processes associated with a TreeView control for more details.

For a TreeView Table control
The "Collapse/Expand" process of a treeview table in the code editor expects no parameter.

When this process is run by ExecuteProcess, the following syntax must be used:

ExecuteProcess(<Name of TreeView Table Control>, trtCollapseExpandBranch)

Calling a global component procedure

ExecuteProcess is used to call a global component procedure. To do so, use the following syntax:

ExecuteProcess(<Component>.<Set of procedures>.<Procedure>, ...
trtProcedure)

Example:

ExecuteProcess("MyComponent.Set_WDExample.MyProcedure", trtProcedure)

In a thread started by a component, ExecuteProcess cannot be used to call a local procedure of a window of the host project.

You must use a global procedure of the host project to call the local procedure of the window.
