Searching for object allocations

 

Using the Object Query dialog below, you can search for allocations of objects by their datatype.

 

The object query dialog is very similar in behaviour to finding addresses.

 

 

The object query dialog

 

To show the Object Query dialog, choose the menu option below:

 

Query menu choose Query Object... displays the Object Query dialog

 

Or use the following icon on the Query Toolbar.

 

 

 

 

 

 

 

Search criteria

 

Just choose the object type for which you want to find allocations.

 

•Object type choose the datatype of the objects you want to find

 

 

Allocation types

 

As well as allocations you can search for reallocations and/or free events:

 

•Allocated search for allocations
 

•Reallocated search for reallocations
 

•Deleted search for free events
 

 

Query results

 

•Query performs the search
 

The search results are added to the list in the dialog.

 

•Clear clears all the results from the list
 

The list is not automatically cleared with each search, so you can compare results of different searches

 

You can expand the search results, and double click the data items to edit source code in your preferred editor.

 

 

Finding referenced objects

 

Within the search results, you can select an item and find potentially referenced and referencing objects:

 

•Referenced... find other objects which are referenced by the selected object

 

•Referencing... find other objects that reference the selected object

 

Referenced pointers are listed in the same references dialog used when finding addresses.

 

Also see the examples below.

Examples of searches and finding referenced objects

 

Memory Validator has an example program with which to safely explore all the features available.

 

Among the datatypes it uses is CString and CTeststakDoc, used in the examples below.

 

Searching for object types

 

If you searched for a datatype with many allocation instances, they would all be listed.

 

For example CString

 

 

 

Below are the results of searching for CSingleDocTemplate datatype allocations.

 

The results are expanded to show the source code surrounding the allocation point.

 

 

Referenced

 

Selecting the object in the list and clicking Referenced finds referenced objects and should include CTeststakDoc being referenced by the CSingleDocTemplate object:

 

 

Referencing

 

Clicking Referencing to find objects referencing the CSingleDocTemplate object might show something like:
