The IQueryForm interface is implemented by a query form extension object to allow the form object to add forms and pages to the system-supplied directory service query dialog box.
The IQueryForm interface inherits the methods of the standard COM interface IUnknown.
In addition, IQueryForm defines the following methods.
| Method | Description |
|---|---|
| Initialize | Initializes the query form object. |
| AddForms | Add forms. |
| AddPages | Add pages. |
A query form extension object must be registered in the Windows registry to be available to the query handler. This is accomplished by adding the following registry key.
HKEY_CLASSES_ROOT\CLSID\<query handler
CLSID>\Forms\
<name of query form
extension>
The <query handler CLSID> key is the class identifier of the form handler. The <name of query form extension> key is the unique name of the query form extension. This name must be unique within the Forms key. It is suggested that the string form of the class identifier of the query form extension be used for the name.
Under the above key, the following registry entries must be made.
| Registry Entry | Description |
|---|---|
| CLSID | A string value that contains the class identifier of the object that implements IQueryForm. |
| Flags | A numeric value that contains a set of flags that define the
behavior of the form. This can be zero or a combination of one or
more of the following values.
