Hi,

Can someone tell me what the SearchResult parameter does as it doesn't
seem to do what I expected. I thought it would be true if a typed
value was not found in the list, but it doesn't, it always appears to
be false.

Actually can someone point me to the help for RxDB component which I'm
struggling to find so having to experiment with all the components.

Thanks
Dave

Hello, Dave.

I've never seen any documentation for RX. There are XML source files
in the Lazarus CCR at https://sourceforge.net/p/lazarus-
ccr/svn/HEAD/tree/components/rx/trunk/docs/, but they're in Russian.

Hi dsiders,

Thanks I'll take a look.

I have somewhere the old help files for the RxLib; give me a little
time to search for them and an address where to send them (PM me with
it).

Or you could google "RxLib"; I'm sure it's still somewhere out there

ETA: Found them quicker than I thought but it's a 1Mb zip: I can't
attach them here.

Thanks lucamar, I think I've sent you a PM with my email address in
it.

I haven't received it (yet?) but in the meantime you may want to look
in Thomas Müller RxLib page or FraserSoft's RxLibrary Help. HTH

Note that the help files are in the old hlp file format. If you are on
Windows 10 you will notice that this format is no longer supported. I
remember that once I had found a trick how to activiate this
nevertheless, but as usual I forgot it...

Now I tried to convert the hlp to chm which can be opened by the
Lazarus chm viewer, lhelp:
Downloaded the English RX help file from
http://www.frasersoft.net/rxhelp/index.htmUsed HelpDeco and HlpDecoGui
to decompile the hlp file and extract html files and encorporated bmp
images Used Microsoft Html Help Workshop to create the chm file from
the project file created by the decompilerNote that the decompilation
process is not very precise and some features have been lost, e.g. the
help contents displayed usually on the first page of the help vierwer.

Unfortunately the chm file is too large for an attachment here.
Therefore, I added it to the rx repository on CCR - I hope AlexTp does
not mind...

To find the help items for TRxDBLookupCombo type this word into the
search filter of the help viewer.

HLP files were left out in the cold with the release of Vista  . Some
googling led me to this page in WindowsReport: Full Guide: How to open
.hlp files on Windows 10. Seems to be quite complete.

Thanks guys, yes I found that the I needed to do something to see the
help files. I'll take a look and see if I can get them loaded.

Thanks again
Dave
