What does the _APS_NEXT implies?

[Pradeep]

Hello,

The resource.h file in a mfc project contains 4 #defines
_APS_NEXT_RESOURCE_VALUE, _APS_NEXT_COMMAND_VALUE, _APS_NEXT_CONTROL_VALUE,
_APS_NEXT_SYMED_VALUE

Obviously the _APS_NEXT_RESOURCE_VALUE is used for allocating the id of the
next resource. But how is the id for a string in a string table allocated?
The MSDN document(TN035) says that the resource value should be between
1-0x6FFF, but the string ids go beyond this range. Also the string ids and
the resource ids of other resources are not unique. How is it handled? or
does it have a different range.

Also when is the _APS_NEXT_CONTROL_VALUE incremented? Is it when a new
control is added to a dialog/form? or is it incremented during some other
time?

TIA,
Pradeep

I just experimented a little with this. Stringtable entries take their
values calculated as the next free value from the selected string in the
table.
Different types of resources can have identical values - *must* have the
same values in some cases (witness menu items and string table entries for
the statusbar/tooltip), controls can even have the same value, as long as
they are located on different dialog templates.

Do what I did! Create an empty project, adding resources, inspecting the
_AFX_NEXT definitions. Change the _AFX_-definitions by hand and add yet more
resources.

_APS_NEXT_RESOURCE_VALUE is the next symbol value that will be used for a dialog resource, menu resource, and so on. The valid range for resource symbol values is 1 to 0x6FFF.
_APS_NEXT_COMMAND_VALUE is the next symbol value that will be used for a command identification. The valid range for command symbol values is 0x8000 to 0xDFFF.
_APS_NEXT_CONTROL_VALUE is the next symbol value that will be used for a dialog control. The valid range for dialog control symbol values is 8 to 0xDFFF.
_APS_NEXT_SYMED_VALUE is the next symbol value that will be issued when you manually assign a symbol value using the New command in the Symbol Browser.
