Description
Returns the state of a DataWindow or DataStore. You must call GetFullState first to set up the state information. This method is used primarily in distributed applications.
Obsolete method
GetFullStateBlob is obsolete and should not be used, because the DataWindow Web Control for ActiveX technology is obsolete.
Applies to
Syntax
Web ActiveX
string dwcontrol.GetFullStateBlob ( )

Argument |
Description |
|---|---|
|
dwcontrol |
A reference to the DataWindow control for which you just called GetFullState |
Return value
Returns a string whose value is the DataWindow state blob set up by GetFullState.
If dwcontrol is null, the method returns null.
Usage
GetFullState and GetFullStateBlob are used in conjunction with SetFullState to synchronize two or more DataWindows or DataStores. For details, see GetFullState.
Examples
These statements use GetChanges to capture changes to a DataWindow control on a client. If GetChanges succeeds, the client calls a remote object function that applies the changes to a DataStore on the server and updates the database:
blob lblb_changes
long ll_rv
ll_rv = dw_employee.GetChanges(lblb_changes)
IF ll_rv = -1 THEN
MessageBox("Error", "GetChanges call failed!")
ELSE
iuo_employee.UpdateData(lblb_changes)
END IFSee also
