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

Hello,I'm Migrating from V9.7.03 to V10.4.03. After compilation all my components I saw that glyph attached to button no longer displayed.For example : one Button named "DETAIL" Data type is I^ (image - glyph)Initial value is : Chevrons (that is the name of the glyph)Database interface is :@LIB::IMAGE The glyph file chevrons@hematos@usa@iw04020020.gly existes in the .\resources\gly\What is wrong ?Thanks for your help

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

Does everyone's IDE start page look like the following, or have I got something messed up in the ini files somewhere? The dates appear to be nonsensical/missing.  Regards,  Iain------------------------------Iain SharpHead of Technical ServicesPci Systems LtdSheffield GB------------------------------

Hi freaksI was forced to upgrade ourWindows-Server and SQL-Server to Version “2025”No problem but now, when I connect (from our application) the first time to the database it takes 8 secondssql/print "SELECT top 1 1 FROM aTable", "DEF"Profiling on MS-SQL give me no hint, as the duration of all action are a few microseconds.Using procmon results in this picture UnifAce connects and deconnect several time. Every reconnect last 0.5 seconds so in total we are near the eight seconds (measured by counting aloud)So what’s going on here?As I said, it's really just the simple SQL/print statement, nothing else.Oh yes, when I start the IDF, I got thisWhat happens here for about two seconds?Thanks for any hintIngo 

HiDoes anyone know where the “vlisting.xml” is found nowadays?Akerman:Here is an export of my custom listing viewer implementation: vlisting.xml.Regards RogerW 

Hi Unifacers,I would like to understand how to deal with VARIANT datatype in a COM interface with Uniface.VARIANT datatype as far as I’ve understood from Microsoft documentation is accepting either strings or numeric or any other datatypes and based on the datatype received it is reacting accordingly.Giving an easy understandable example (but the problem is generic):an Excel workbook could be composed from one or more worksheet; when more worksheets are available the program should select the one it wants to work into.After loading the Excel type library in Uniface and opening the workbook the operation to be called to move to a specific worksheet is:    sheets->get_item(handle out, variant in)- First param is an output parameter and it is the handle/pointer to the requested sheet- Second param is a VARIANT and it could be either a number or a string; when number it means the ordinal number identifying the requested worksheet or when string it means the name assigned to the workshee

We are loading a third party web page to an HTML widget in a DSP which is in turn loaded into an HTML widget from our C.S. Application. The 3rd party web page is displaying the dates etc in American format. and the navigator.language when queried in the inspector is “en-US”. The user/machine I am running the client application on is set to language “en-GB” when I run chrome and use the inspector. It is important that I can set the accepted languages and preferred language for my application as people will be confused by the date formats. How do you control these settings in the HTML widget/cefrender? NOTE, I am currently jumping through hoops to set the locale in the DSP code, but this is a 3rd party software… Regards, Iain
