Method Detail

PUBLIC AssignBindingSourceColumn (BindingSource, character, Object, Control)
Purpose: Assigns a value to a BindingSource column
Notes: As it is not directly possible to modify the BindingSource values,
it is required to use a data bound Control. For this purpose the
reference to a (loaded) Control needs to provided. The Tag property
of this Control will be used to Write the value to the BindingSource

Parameters:
poBindingSource Progress.Data.BindingSource
The reference to the BindingSource
pcColumnName CHARACTER
The name of the BindingSource Column to assign to
poValue System.Object
The value to assign to the column
poControl System.Windows.Forms.Control
The reference to the Control to use the Tag property for Binding to
Top

PUBLIC AssignFromBindingSource (handle, BindingSource)
Purpose: Assigns values from the ProBindingSource:InputValue dictionary to
the fields in the buffer
Notes: Code might need adjustment in 10.2B05 when the UseFullFieldNames
propertiy is implemented

Parameters:
phBuffer HANDLE
The Buffer handle to assign to
poBindingSource Progress.Data.BindingSource
The ProBindingSource to assign from
Top

PUBLIC AssignFromBindingSource (handle, BindingSource, character, character, character)
Purpose: Assigns values from the ProBindingSource:InputValue dictionary to

propertiy is implemented

Parameters:
phBuffer HANDLE
The Buffer handle to assign to
poBindingSource Progress.Data.BindingSource
The ProBindingSource to assign from

Top

PUBLIC CHARACTER BindingBufferFieldName (handle, character, character)
Purpose: Returns the Buffer Field Name for a BindingSource field
Notes: Optional support for UseFullFieldNames (10.2B05+)
