Hi all,I am trying to trace down an annoying issue related to opening files in Uniface Runtime but unfortunately I am not able to identify an origin and a solution.Here it is the scenario:    - A centralized server (Windows 2019 Datacenter) sharing a disk    - All users (normally 120 but up to 150 concurrent) refers to this server to startup a Uniface application in C/S mode    - Log is activated for all sessions ($ioprint = 1)The system is up’n running 24x7 and issues I am going to list are happening mainly from 8:00 to 20:00 when most users are at work but there are cases also outside this timeframe like in the evening (20:00 to 24:00)  and also in the middle of the night (00:00 to 06:00).Issues:    - 20% (extimated) = daily Uniface sessions terminating without any signal or message or other… nothing!    - 79% = Session unable to write log file on shared disk (message:    ULOG Error: Failed to write to .\log\[NETWORK_NODE_NAME]_[PROCESS_PID].log) in this case a UNIxxxxx.log file is c

I'm having trouble adding blank lines, for example to create a new trigger; I can only do it by pasting lines and writing over them. Also, I haven't been able to use the GOLD Key.

I am trying to look at changing to using the new UX widgets. The ux-button documentation states there’s a property “Icon” which Defines the name of the icon as it exists in the ui-fabric-core library. If name is not specified, no icon is displayed. The default is no icon.  I can find no other references to ui-fabric-core by searching in the documentation, nor does it apparently show up sensibly in my webapps folder(s). How can we find out the name of the icons available?  How can we add new icons so they are available to the ux-button (or others)?  RegardsIain

Good evening, I am testing the programmes following the upgrade to Uniface 10.4.3 and am encountering issues when calling a service located in another repository.For example, from application A, I call it using `newinstance "MY_SERVICE", LV_HANDLE` and get error code -58.MY_SERVICE is referenced in the ASN in the [FILES] section as MY_SERVICE.SVC          \\server\qxsrv10\PROJECT\SVC\MY_SERVICE.SVCI can’t find a solution.Has this happened to anyone else? Anna Lisa

 Practically every solution needs unique identifiers. It’s a simple concept—but an essential one—used in almost every system, past, present, and future.While there are many approaches to generating unique IDs, choosing the right one matters.This short video demonstrates a quick and elegant way to generate unique ID values with minimal effort.

Our environmentUniface 10.4.03.014. MsSql driver U5.2 connection pooling:off procs : on The stored procs for INS/DEL/UPD/FET are re-created for all entities used in our application.Our problem:           - we see following statements when tracing our application.                          create procedure dbo.[log_buffer_INS]  and othersOur questiondoes this harm the performance why does uniface needs to create these procs if they are existing?One special remarkwe do use different drivers that refer to other databases

Hi FreaksWe have an archive system (not written with Uniface) consisting of a server and clients. The server and clients communicate via HTTPS. The server also allows a third-party system (in this case, a Uniface application) to communicate with it via HTTPS/REST.That works so far.Now I have some very large files that I want to download from the server. When I use the archive client, a PDF file over 400 MB in size appears in seconds.But when I try to download the file in Uniface, it takes over twenty minutes!What is slowing Uniface down so much here? (It can’t be the server, the HTTP interface, or the network.)Does anyone have any idea which parameters I need to pass to DUMP_FILE_CONTENTS so that it also downloads in seconds here?TIAIngo

 Nobody likes maintenance downtime, missed SLAs, or broken communication in a live application.But what happens when you need to reconfigure your production uRouter—deploy an additional solution, repartition an existing one, or enable a debug path—all without disrupting the running estate?This short video shows you exactly how to do it.

Microservices with Uniface in DockerAuthors: Tony Rusinovic, Jonke Korzelius and Jorge Núñez-OrellanaBackgroundIn our article '5 Reasons to put microservices on your To-Do list in 2021 ' we presented the benefits of deploying applications as Microservices. As follow-up we want to share our thoughts on Microservices deployment with Uniface, the role of containerization, and planned product enhancements that will help you to deploy Uniface applications as Microservices. It is also a topic of the Uniface Universe webinar on June 10th.                                 Do you want to know our thoughts on how to assist you in deploying Uniface Microservices?IntroductionAt Uniface, we always try to enable you to embrace technological trends to serve your business. With the arrival, and hype, of Microservices, we want to explore in which area we can help you most.We hypothesize that if w

GuudeI was just trying to download large files using UHTTP: In the documentation, I found an option called "chunk" for UHTTP, along with an example:-- Directly from the Uniface documentation --Chunked DownloadvUhttp->SET_FLAGS(8 ) ; GET send headersvUhttp->DUMP_FILE_CONTENTS("your.zip", "chunk=256k")repeat vUhttp->GET_CONTENTS_INFO("range", vInfo) putitem/id/case vHeaders, "Range", "%%vInfo" vUhttp->SEND(vUrl, "GET", "", "", vHeaders, "", vResp) vUhttp->DUMP_FILE_CONTENTS("", "")until (<DefineCondition>)vUhttp->CLOSE_FILE()But that doesn't work. After a few "small" tests, I figured out that this loop isn't necessary at all; even with "chunked" mode, a single call to SEND(GET) and DUMP_FILE_CONTENTS is sufficient.In what scenario is the example from the UnifAce documentation supposed to apply?

March Hare Software have just released an updated UD6 - Uniface Version Control for Uniface 10.4.03, and all previous releases of Uniface back to and including Uniface 7.UD6 is a “database driver” to store your Uniface source code in text files, so you can use any “normal” devops processes around version control, build management, continuous integration, testing, etc. etc.A quick video of how to use GitHub and Uniface 10 with UD6 is available here:  With the help of my team here, a few years ago we created an open source Eclipse development environment for Uniface.  But I think that the Eclipse development environment has been superseded by VS Code.  I’m toying with the idea of making a VS Code environment for Uniface.  Along with Uniface source code in text files with UD6, it would simplify the use of Claude or other generative AI programming with Uniface.  I’m curious as to feedback from the community if this is something you would find useful?I’ve been the lead developer of UD6 for

HiNow I’m on thin ice.I have a Uniface9 service (self-contained) that has changed an entity's read trigger, i.e. what is in the data model's read trigger is overwritten in the form.When exporting and importing to Uniface 10.04.3_038, that what is in the entity's read trigger is still used. Is this correct?Does it have something to do with this?; Migration Logical: Specify whether precompiler directives are generated to prevent ; triggers and entries from being inherited in selected cases.     ; 0 = do not generate     ; 1 = generate precompiler directives (default)MIGRATION_SCRIPT_V9_INHERITANCE = 1Regards RogerW

We are using DLL's with COM interoperability in our Uniface application. Up to today we use C# / .NET Framework 4.8, but want to switch over to C# / .NET Core to be more in line with all other written applications written in C#. I managed to create a (relative) simple DLL with .NET Core, publish it and create a Type Library. I can import that TLB file into Uniface 10 and compile the signature. But when instantiating this component I get an error stating “Unable to get COM type information for COM class”. What could be wrong?

HelloWe have installed Uniface IDE locally on every developer laptop/pc.I wonder where the tabs (editors?) are saved as you also see the components edited by other programmers?Is it possible to see only your own editors?Regards RogerW  

Hi all,do you know if Uniface 9.7.04 runs on Windows server 2025?ThanksAlessandro

On out development server, we have several installs of uniface for different uses (devel, testing, ‘live’ etc.) Some of these I can tell apart in the “Programs and Features” because they are different versions or patches. Others I cannot. Having just uninstalled the wrong version in an attempt to fix another problem, the question is. Is there a trick to naming the installations inthe Programs and features MMC so we can tell them apart. The info gives us version and install date, but not install path, and I can’t see any sensible way to differentiate them. Iain

Currently in our version control system, we have exports of each component we generate in Uniface, which are then imported during check out and then exported during check in.  In our migration from 9.7 to 10.4, one of the things I would like to do is do a full export of everything from my 10.4 repository to put back into version control.Individual components are pretty easy, as we can name the component we want to export and pass that to $ude, since we know the name of the component from our version control system.  What I would like to be able to do is from within Uniface, list all of the components programmatically and then for each individual component, export each component to its own XML file for check in.  Is there a way to list all components or even all objects in the repository programmatically? 

Hello all, We are currently in the process of upgrading from Uniface 10.4.02.052 to 10.4.03.019 and have noticed a difference in behaviour with our HTML widget that we are not sure how to resolve. I believe this is probably due to a newer version of the CEF framework that is included in this release. I know that Uniface is not responsible for CEF functionality, however, I wonder if anyone has encountered the following issue or can suggest a solution.... We have a form component with a HTML widget on it. We communicate with a third-party via REST APIs and they send us back the URLs of a number of images, and we then update the HTML widget to render these images. The URLs to these images are stored on a CDN. Whenever the HTML widget renders these images the following error is recorded in the message frame: HTML Widget: Third-party cookie will be blocked. Learn more in the Issues tab. The HTML widget displays many images and so this error appears many times. Despite this, the images are s
