DDE Request function.

You must enable the function with TdmgwHookEnableUserHooks function by

returning a value with the TDMGW_HOOK_ENABLE_REQ_POST_CON bit set.

The TdmgwHookDdeRequestPostConvert function is called only if there is an

automatic built-in data conversion between the Tandem data representation for the

current data element and the clipboard format cfFormat. If the

TdmgwHookIsConvSupported function is enabled, then it also must return non-zero
