  • I don't know anything about subclassing. I am curious to learn more, as I could probably make use of it . How did you get that combo box to look like that? I would like to create a combo box whose drop down contains images. Is that subclassing? E…
  • Hi, No I am not talking about the database. I am talking about associating the output representation of a piece of data with its input representation. The radio button in OI has this feature. I was hoping the combo box had it to, but it doesn't l…
  • Actually, that list appears to be a list box, not a combo box. So that explains that. Still wondering how they got that black rectangle to appear in that combo box though.
  • Hi, it actually is possible out of the box: '' I changed "something" and I am now able to select the text by clicking in the ell (but not the text). So yes, it's perfect. Thanks
  • They have now admitted that what they did caused the issue. So mystery solved.
  • We have now figured out that the IT Department had done pen testing on the computer running the UDH at exactly the time the UDH crashed. They are claiming however that their pen testing, which apparently tries to connect to every single port on the…
  • I see, i guess I was hoping that it would be possible for the hyperlink to only apply when the mouse were over the text rather than the cell. I will try your solution. If that doesn't work, i will make a right click context menu over the cell give…
  • Hi, the reason I am asking all these questions is that our LH program didn't work for 6 hours. We emailed Revelation and received a response from them. Unfortunately, we still don't know what the issue was. And yes, that book I linked goes into to…
  • I found a free online book about "CIFS" and "SMB". I will give this a read: http://ubiqx.org/cifs/
  • Oh, i thought it contained the code that communicated a read/write/lock from the client to the lh server. I must have misunderstood.
  • Thanks, Yes that does help. How come I can't see a process for netdrv.exe in task manager? I am running OI right now on my computer. Is this because it's a library, even though the file extension is .exe?
  • Hi, what is SMB and why does OI use it? I don't really understand it. When I look in wireshark when OI is running, I can see a lot of SMB requests and responses. During the outage I also saw a few "SMB" errors like bcrypt.dll and imhost.dll could n…
  • Thankfully there are other people here, and it's not just me, but no one is very familiar with the linear hash/ud program. I will look through the knowledge base. We have sent an email to revelation, so hopefully they can help us.
  • Thanks, i will try this when I have time
  • Ok, to give a basic example. Let's say I wanted to debug our website. Since I understand JavaScript and I understand HTTP, I am in a very good position to debug any issue that happens with our website. Also, I can easily see what is going on using …
  • Seems to be working now...scary. OI is one big mystery. Where can you get resources explaining how OI works?
  • Never mind, I found post on the rev forums about this error code. But apparently the team has already tried what was advised in the post, and still doesn't work. So it's something else. ----------------------------------------------------------…
  • Hi, yes, post_event does work for a bit, then it stops working. To get it to work again, I have to restart OI. So I must be running into the "unique situation" you referred to. The code that seems to break the post_event changes the VPOSITION pr…
  • Actually don't worry, I am not going to bother debugging it, and I am sure it does work. I have thought of a way of doing it without using an "omni-event".
  • Ok thanks, now that you have explained that it's not necessarily OI but possibly the network, I will try to figure out why this is happening. But my point was that other apps that use the network are fast, that's why I thought there was somethin…
  • Hi, but why is OI particularly bad over a network? Is this an inherent flaw in OI, or a configuration setting?
  • I actually don't think OI is a slow as I said. When I run OI on my workstation, reads and btree.index are really slow. But when I run OI on the same computer that the "oi server" is running on (not really sure what OI server means -- to be honest …
  • @DonBakke yes. Le t me explain more of the context here. We are remaking my company's callcentre system in OI. At the moment, it's a javascript app. As part of the redesign, I want to "fix" customer notes. This is the problem with the current s…
  • @barry Let me explain more. This company has been around for 23 years, and the notes system has been in place since then. So far, we have 5 million note records. The key to a note is: customer_number*note_no The note_no is a sequential key. We …
  • But I will mention one more thing, because it might impact the design. We want to create a form that works like gmail. When you open the form, it will display a preview of all of customer's notes within the last 120 days in a grid. But we only wan…
  • Ok thank you for your help. I will discuss these ideas with my team and see what they say.
  • OK thanks for clarifying, that's not how I was going to do it, but now i will consider it. My original idea was to store everything thing in one table, and link notes via pointer fields... Isn't one table simpler than 2 though?
  • @DonBakke I would then create a relational index so that each child note relates back to the parent What is the difference between a relation index, and a btree index?
  • Yes, my preference is based on performance. Otherwise, solution 2 would be perfect. But i think if I limit the amount of data returned to the last x amount days of notes by default, it won't be too slow. But it's still worrying that the system is …
  • yes, we need to display all of the colour options for a product, what I have in mind is an edit table with two columns, the first containing the colour options and the second the size options. When you click on a particular colour, the second colum…
