4.9.8.3 IFdtContainer::SaveRequest()
| This method can be called in the states: |       |
|
HRESULT SaveRequest ( [in] BSTR systemTag, [out, retval] VARIANT_BOOL* result ); |
Description:
| Informs the Frame Application that it should store the changed data. |
Parameters:
| systemTag | Identifier of the device instance |
Return Value:
| result | TRUE Data set will be saved FALSE The operation failed. |
Behavior:
| Via this method a DTM notifies the Frame Application that it wants to save its data. It is up to the Frame Application to store the data. The Frame Application get the data it has to store via the standard storage interfaces. Transient data remains in transient state until the Frame Application successfully completes IPersistXXX:Save(). |
Comments:
| This method is the only method to inform the Frame Application that it should store the changed data. Even if the IPersistXXX::IsDirty property is available, it will not be used by a Frame Application. The Frame Application could also initiate the persistence interface of a DTM by itself. Concerning multi user access the Frame Application must reject the save request if the DTM has no write access rights. |
