Uniface®

Our IT services have employed a company to test vulnerabilities. They are reporting an out of date Oracle Java version on our machine, which is patched to patch 10.4.3.042What do people know about updating the Java version independently? Is it ‘safe’ to do so? Or will bits of the uniface environment stop working?  Where is the installation folder to overwrite, or is that automatic?  (afterthought) WHat happens when we patch uniface, does it reset, or is it smart enough to not update a later version? Regards, Iain

Hi all? I installed the latest Patch  (044) in my development.After transfering a form to test, I get an error .[] User action failed to complete. Unexpected exception. [error=-100003] Repository data found, of which the K-version is too high. The form is imported but I can’t open the IDE in test and prod any more :  

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

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

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? 

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

HiI have installed patch line Uniface 10.4.03.036 today. The Ide startpage tries to load “Loading community topics”, but it’s just spinning.If you restart the Ide, you may be lucky and it loads, but usually just spinning.It doesn’t lock the ide but..I think I have seen something about this in the forum, but I can’t find it.Regards RogerWStartpage 

We do all our exports to CSV by lfieldump and this works for yearsNow, however, a customer came up with the idea of using a DOS environment variable to determine the directory instead of fixed directories.So instead of "Q:\outpute\export1.csv,"it should now be "%app_export%\export1.csv"(where app_export is defined differently on each client).Unfortunately, Uniface cannot handle this; the file system converts it to "?app_export?\export1.csv," and the file system complains.Is there a simple solution for this, i.e., any letter combinations that can be used at the file system level to resolve "%%app_export%"?Of course, I can use a few tricks to ask Windows/DOS what the resolution is before each fieldump, and then replace that part. But I'm reluctant to check all our programs for this and make changes :-)A customer 

I have a CS form with an HTML widget on it. The CS form has a proc on it as per below. entry lp_refresh $fieldhandle("d_to_do_list")->$widgetoperation("JS:uniface.getInstance('SYD_TO_DO_LIST').activate('refresh')")endThe DSP SYD_TO_DO_LIST has an operation refresh as per below. Where “widget” is the name of a DSP container widget. operation refreshpublic webscope input output operation all_instances().refreshendscope if(widget != "" & widget != "SYD_BI") activate widget.refresh() endif return 0endThis successfully executes the refresh operation on the DSP contained by the widget container, and in turn on a widget contained by that container. So it all appears good. However, if I inspect the cef process (ENABLEDEVTOOLS=true), it builds up uncaught exceptions as per below, every time the refresh is fired. NOTE the refresh works, it just stacks an error in the dev tools.  VM124:1 Uncaught TypeError: uniface.getInstance(...).activate(...) is not a function at <anonymous>:1:58

We have a web page built in against an HTML widget in our CS. Clicking a button on the web page uses a JS trigger to start loading a CS form and populating it with data. Whilst this is happening (can be up to 10 seconds before the entire form is loaded/shown) the web page is active and there is no indication at the client end that anything is happening. I’d like to turn on the ‘Processsing’ function, as per the refresh/loading of the page in the first place, from JS calls to the HTML widget before the activate of the triggered form, and off again after the form is loaded. (So the user doesn’t think nothing is happening and click the button several times (causing multiple instances of the form to fire up). Is this possible? Putting the DSP into ‘locked/processing’ state without the round trip to the server refresh… Iain
