Hi, We're a very small company that has an app used by a few local school districts that we *think* was last built with Micro Focus Visual COBOL for Visual Studio 2013 that needs a small change to extend some calendars and then be recompiled.  The app runs on Windows.  However, the developer's health/memory ( who built and maintained the app for the last 35 years) has deteriorated such that he is no longer able to do so.  He's only able to tell us that he used Visual Studio 2013 to edit the source and ran some command via the Windows Command prompt to compile it.  He last compiled it in 2022. So, needless to say, we could use home help.  And, of course, we need this done in the next couple of weeks.  We know very little about Cobol (though I am a .NET web developer).  Ideally, someone here would be willing to do some freelance work to compile the app for us.  If we can't find someone to help, then we'd need some pointers on where to start and try to do it ourselves using VS Code .  

Hi there, Just installed "Visual COBOL for Visual Studio Personal Edition 10.0" on Windows 10 Pro. Can't open: Data File Tools. Getting this java error message: "A Java Exception has occurred" This is the Java version I have.java version "1.8.0_451"Java(TM) SE Runtime Environment (build 1.8.0_451-b10)Java HotSpot(TM) 64-Bit Server VM (build 25.451-b10, mixed mode)Thanks.Gagan

There is a difference in the size of the .gnt file generated when compiling the same component for two different environments (Test and Production). The same compiler is used, with varying input copy assignment paths and compiled object delivery paths. We have compared the compiler lines and found that they are identical and contain the same instructions. I appreciate your support and guidance in identifying the difference and successfully delivering compiled objects with the same file sizes for both environments. Thank you very much.------------------------------alejandro rodriguez manceraconsulting IIOptima LATAM------------------------------

Hi there, Is it possible to extend Visual COBOL PE 9.0 license ? If yes, then what's the process  ? Thanks.Gagan

When I call the "SetVolumeMountPoint" function in Kernel32.dll, I get the following error: Error code = 1008: An attempt was made to reference a token that does not exist.  I get this error from any function I call in Kernel32.dll.  However, I can call other Win32 functions from sample code I've seen without a problem.  Any ideas?  (I've included a code snippet here.)                call WINAPI "SetVolumeMountPointA"                   using by reference RestoreDrive,                         by reference VolumeGUID                   returning                         dwErrorCode               end-call                if &nbsp

Using vc_build_tools_dockerfiles_10.0_windows_pu04 we build and license the docker container. When the container is run in 'process isolation' where  can see the java process from the license daemon running using task manager on the host.These containers use a mounted volume.We run multiple  Visual COBOPL compile containers. The host machine is Windows Server 2022 datacenter.Today ALL our COBOL  containers are failing and it seems to be due to the java process. The contains start and perhaps you start to compile a few times, then it sems the java process from the autopass daemon consumes such high CPU that the containers fail.Remember this is process isolation. We  can't run hyper-v because the host doesn't support nested hyper-v.If we quickly kill the java process we can exec into the container to do some exploratory work, but the question is what are we looking for?We  even stopped all containers, removed all the images and rebuilt them all, but we get the same behaviour. No updates

How do I construct a Resources .rc (or otherwise) file to add to a Visual COBOL project to populate the Details tab on a .EXE/.DLL Properties? I would like to be able specify Copyright, Product name, Product version, and File description. I have created a .rc file that contains: 1 VERSIONINFO  FILEVERSION    1,2,3,4  PRODUCTVERSION 5,6,7,8  FILEFLAGS      0BEGIN  BLOCK "StringFileInfo"  BEGIN    BLOCK "04090000"            /* lang-charset : US. English, ACSII */    BEGIN      VALUE "CompanyName",      "Company Name\\0"      VALUE "FileVersion",      "9.10.11.12\\0"      VALUE "LegalCopyright",   "Copyright (C) 2025\\0"      VALUE "ProductName",      "Product name\\0"      VALUE "ProductVersion",   "13.14.15.16\\0"    END  ENDEND But the only property that gets used is the initial FILEVERSION (1,2,3,4). How do I get the other values into the EXE/DLL Properties?------------------------------Nick KayeRocket Software Forum Member------------------------------

Hello, I've inherited a project where I am to upgrade the Micro Focus compiler from version 4.0.38 to version 10 at my company. I've installed the Build Tools because we want to continue to use the command line only setup for a while longer (we have lots of batch files that drive our process) and I've started recompiling with the new compiler. However, I realize now there are no cfg files created with this version. I've searched, or so I think, the documentation and can not pinpoint how to handle the lack of cfg files. I'm primarily a help desk jockey and cloud administrator here, so any guidance here would be great appreciated. TIA. ------------------------------Jeff------------------------------

I was at a breakpoint in my managed code program and I was looking at the properties listed for a menu strip.  One of them was "DisplayedItems" with a heart shaped icon beside it.  It is a collection and I can see the items in the collection at the breakpoint.  I would very much like to use the information in this collection in my program but that property is not available to my program.  Why not?  If my menu strip is too wide to see in my window, I would like to increase the width of my window.  This collection would tell me if any of the menu items are not displayed.  ------------------------------Lee RobinsonSoftware Development ManagerNew Hampshire Admin Office of the CourtsConcord NH US------------------------------

Customer is in the process of migrating our customer's COBOL application (Visual COBOL) from a physical RHEL 7.9 server to a VMware-based RHEL 8.10 environment. The customer is currently using a High Availability (HA) clustering setup with NFS as the mount point for data storage in their RHEL 7.9 environment.As they are moving to VMware, the customer has the following concerns and questions regarding the HA clustering and management of data files in the new setup:Handling HA Clustering in VMware:What are the best practices for handling HA clustering for the virtual machines (VMs) in VMware, particularly concerning data files that are shared among multiple VMs ? How do we ensure seamless failover and VMotion of VMs while maintaining access to shared data files during maintenance or failures?VMware HA Considerations for Active-Active / Active-Passive Configurations:For Rocket COBOL, can you provide guidance on configuring HA clustering in an active-active or active-passive mode for the V

I am a 35+ year COBOL programmer and I would like to create some programs for personal use at home.    I have tried other languages but I am most comfortable with COBOL.    How can I get a copy of VCPE?   Looks like every one I find on the Internet is for retired versions of Studio.

We are working with a 3rd party and they will need to get data to the repository on a regular basis.  The third party uses an AWS storage solution, S3, which uses an access key-pair to access. We are currently on version 5.0 of Visual Cobol - does that version handle something like this, or would we have to upgrade to 10 first?  Would we maybe have to write it in something like .net?------------------------------Amy McDonoughSenior Software DeveloperN.

Hi, I've got something like this in my .pco file : EXEC SQL   SELECT TO_CHAR(CAST(RTRIM(Varchar2_11_char_Column) AS DECIMAL(10,2)), 'S9999999D99') from table INTO :hostvar_x_11 END-EXEC. I get compiler error COBCH0803 : 000576:PLS-103: Encountered the symbol "(" when expecting one of the following: . ) , @ % defaultsymbol The symbol ")" was substituted for "(" to continue. It compiles fine with the TO_CHAR and RTRIM but when I add the CAST, it won't compile anymore.Should this work? Any ideas anyone? Thanks Kr, Stefan ------------------------------Stefan ThysING Bank N VBrussels BE------------------------------

You'll find it here: cs2cobol.rocketsoftware.com If you did a double take at that and are wondering why you might need such a tool, let me explain... Visual COBOL allows you to compile applications directly to .NET bytecode - or even JVM bytecode - opening up a world of possibilities for integrating COBOL with these platforms and other languages. It's not just Java or C# developers who get to enjoy these ecosystems; Visual COBOL developers can tap into their libraries and functionality too. That's where this tool comes in. If you come across a snippet of C# code online and wonder how to express it in COBOL, the C# to COBOL Converter will help bridge the gap. Give it a try! using System; namespace CsharpString { class Test { public static void Main(string [] args) { // create string string str = "C# to COBOL"; Console.WriteLine("string: " + str); // get length of str int length = str.Length; Console.WriteLine("Length: "+ leng

you will no be able to run or compile any cobol program in vs code even you have installed the learned cobol extension or other cobol plugging , here is the error message  Micro Focus COBOL Version 7.0 (C) Copyright 1984-2021 Micro Focus or one of its affiliates.
