4.3.7.2 IDtmDiagnosis::InitCompare()
| This method can be called in the states: |      |
|
HRESULT InitCompare ( [in] BSTR systemTag, [out, retval] VARIANT_BOOL* result ); |
Description:
| Initializes a DTM for comparison of two device instances |
Parameters:
| systemTag | systemTag of a second DTM of the same type |
Return Value:
| result | TRUE Initialization successful FALSE Initialization failed (e. g. a compare is already in progress or the DTM is not of the same type) |
Behavior:
| Initializes the compare of the data set owned by the DTM itself with a data set of a second device. Such a comparison is only possible within an InitCompare() – ReleaseCompare() sequence. The DTM can access the second device data set by requesting the according DTM instance via IFdtTopology::GetDtmForSystemTag() with the received systemTag. To perform a comparison in the background the Compare() method can be called. Starting a compare user interface may perform a user interactive comparison. It is only possible to compare data sets handled by DTMs of the same type. |
Comments:
| Every comparison sequence started with InitCompare() must be closed using ReleaseCompare(). |
