Class TPMDdeGroups (unit PMDdeGrp) |
TDdeClientConv
Usage of a var PMDdeGroups:TPMDdeGroups is restricted to the code between the "brackets" PMDdeGroups:= TPMDdeGroups.Create(OwnerComponent); and PMDdeGroups.Destroy; Create reserves resources: storage for the object and a dde conbersation with the Program Manager. The TStringList PMDdeGroups.Groups contains the names of groups. To get access to more information concerning the group with index G and its items, associate to it an TPMDDeGroup object by PMDdeGroups.OpenGroup(G); OpenGroup(G) is idempotent: more than one call (before a CloseGroup(G)) do not matter. The TPMDdeGroup may be dissociated explicitly by PMDdeGroups.CloseGroup(G); CloseGrp will implicitly release all TPMGFItems and free all reserved resources. Errors are signalled by Exceptions labelled with PMDdeGrp/severity Freeware: P.J. Veger, Best, The Netherlands
