Enclosing interface:

Ddeml

public static class Ddeml.MONHSZSTRUCT
extends Structure

Contains information about a Dynamic Data Exchange (DDE) string handle. A DDE monitoring application can use this structure when monitoring the activity of the string manager component of the DDE Management Library.

Field Detail

FIELDS

public static final List<String> FIELDS

cb

public int cb

The structure's size, in bytes.

fsAction

public int fsAction

The action being performed on the string identified by the hsz member.

Value	Meaning
MH_CLEANUP (4)	An application is freeing its DDE resources, causing the system to delete string handles the application had created. (The application called the DdeUninitialize function.)
MH_CREATE (1)	An application is creating a string handle. (The application called the DdeCreateStringHandle function.)
MH_DELETE (3)	An application is deleting a string handle. (The application called the DdeFreeStringHandle function.)
MH_KEEP (2)	An application is increasing the usage count of a string handle. (The application called the DdeKeepStringHandle function.)

dwTime

public int dwTime

The Windows time at which the action specified by the fsAction member takes place. Windows time is the number of milliseconds that have elapsed since the system was booted.

hsz

public Ddeml.HSZ hsz

A handle to the string. Because string handles are local to the process, this member is a global atom.

hTask

public WinNT.HANDLE hTask

A handle to the task (application instance) performing the action on the string handle.

str

public byte[] str

String identified by the hsz member.

Method Detail

write

public void write()

Description copied from class: Structure

Writes the fields of the struct to native memory

Overrides:

write in class Structure

read

public void read()

Description copied from class: Structure

Reads the fields of the struct from native memory

Overrides:

read in class Structure

getStr

public String getStr()

getFieldOrder

protected List<String> getFieldOrder()

Description copied from class: Structure

Return this Structure's field names in their proper order. For example,

 protected List getFieldOrder() {
     return Arrays.asList(new String[] { ... });
 }
 

IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.

 protected List getFieldOrder() {
     List fields = new ArrayList(super.getFieldOrder());
     fields.addAll(Arrays.asList(new String[] { ... }));
     return fields;
 }
 

Field order must be explicitly indicated, since the field order as returned by Class.getFields() is not guaranteed to be predictable.

Specified by:

getFieldOrder in class Structure

Returns:

ordered list of field names
