Hello,
does xHarbour support hash functions?
Best regards,
Otto

Hash table
hb_Hash() Returns a hash table
hb_HAllocate() Preallocates a hash table
hb_HAutoAdd() Sets the 'auto add' flag for the hash table
hb_HBinary() Sets the 'binary' flag for the hash table
hb_HCaseMatch() Sets the 'case match' flag for the hash table
hb_HClone() Creates a copy of a hash table
hb_HCopy() Adds entries from the source hash table to the destination hash table
hb_HDefault() Returns/sets a default value for a hash table.
hb_HDel() Removes a key/value pair from a hash table
hb_HDelAt() Removes an entry from a hash table based on its index position
hb_HEval() Evaluate a code block across the contents of a hash table
hb_HFill() Fills a hash table with a value
hb_HGet() Returns a hash value
hb_HGetDef() Returns a hash value, or a default value if the key is not present
hb_HHasKey() Determines whether a hash table has an entry with a give key
hb_HKeyAt() Gets a hash table key at a given position
hb_HKeys() Returns an array of the keys of a hash table
hb_HMerge() Merges a source hash table into a destination hash table
hb_HPairAt() Returns a two-dimensional array of a hash table entry key/value pair
hb_HPos() Locates the index of a key within a hash table
hb_HScan() Scans a hash table
hb_HSet() Sets a hash value
hb_HSort() Reorganizes the internal list of the hash table to be sorted
hb_HValueAt() Gets/sets a hash value at a given position
hb_HValues() Returns an array of the values of a hash table

Both Harbour and xHarbour support all these functions but with slightly different names.
hbcompat.ch provides cross translations.

Dear Mr. Rao,
thank you so much.
Best regards,

Hello friends,

does someone know how to use

hb_HGetDef() in xHarbour?

Best regards,
Otto

Just use it the same way as you use it in Harbour.
It works

Dear Mr. Rao,

I am sorry, but this errors out:

Code: Select all Expand view: Embarcadero C++ 7.00 for Win32 Copyright (c) 1993-2015 Embarcadero Technologies, Inc. C:\FWH\samples\timerdlg.c: Turbo Incremental Link 6.70 Copyright (c) 1997-2014 Embarcadero Technologies, Inc. Error: Unresolved external '_HB_FUN_HB_HGETDEF' referenced from C:\FWH\SAMPLES\TIMERDLG.OBJ

But I use an old xHarbour version.
Sure, this is the problem. However, updating the production system is always a challenge.
(Never change a winning team.)
I am now using a workaround with HHasKey() + valtype().

Best regards,
Otto

Dear Mr. Rao,

as a supplement to my previous email.
Since I need this function for the new microservice, I think it will be easiest to switch this project, which is still very small, to Harbour. I'll do that.

Best regards,
Otto

I have this version of xHarbour.
xHarbour 1.2.3 Intl. (SimpLex) (Build 20161218)

Everything is working well with this version. ( including xHarbour + harupdf issue reported in these forums)

I can send this version to you. I am sure you will not have any issues. Please try

Dear Mr. Rao,

Thank you. It would be kind if you could provide me with a download link.

Best regards,
Otto

Please update your xHarbour release. You cannot work with such an old version.
