RxDBLookupComboClosePopup question
« on: December 23, 2018, 09:44:21 am »
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.
Lazarus 2.1 (SVN) / FPC 3.0.4 / FPC 3.2.0 / x86-win64 / Windows 8.1

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.

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.htm
  • Used 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 decompiler
Note 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.
Mainly Lazarus trunk / fpc 3.2.0 / all 32-bit on Win-10, but many more...

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
