ImageGear Professional for Windows ActiveX
IGISISTagValue Object
| ImageGear Professional v18.2 > API Reference Guide > ISIS Component API Reference > ISIS Component Objects > IGISISTagValue Object |
This object is used to obtain the current value of an ISIS tag, and to set the value of the tag. To get the value of a tag, use the IGIsisCtl.GetTagValue method. To set the value of the tag, use the UpdateTagValueFrom Method. The value of a given tag must be of a given type, and may be restricted to certain values. To determine the data-type and representation restrictions, get the corresponding IGISISTagChoice object using GetTagChoice Method.
All of the properties in the IGISISTagValue object will be set by the call to GetTagValue Method. If your application is going to set the values of multiple tags, it can call GetTagValue Method once (to get an IGISISTagValue object), and then set the DataType, ID and Value, and then call UpdateTagValueFrom Method for each desired tag. In that case, your application must set the DataType and Value properties appropriately for the ID.
