Run-Time Applications Additonal Considerations

Accessing your Application using Ride

If you wish to access your run-time application remotely using Ride, you must put a copy of the appropriate Conga DLLs (see Files) in the same directory as your .EXE or workspace.

Additional Files for Syncfusion

Under a licensing agreement with Syncfusion, Dyalog includes the Syncfusion library of WPF controls. These may be used by Dyalog APL users to develop applications, and may be distributed with Dyalog APL run-time applications.

The Syncfusion libraries comprise a set of .NET assemblies which are supplied in the Syncfusion/4.6 sub-directory of the main Dyalog APL installation directory (for example: c:\Program Files\Dyalog\Dyalog APL-64 19.0 Unicode\Syncfusion\4.6.

If you use any of the Syncfusion controls in your runtime application, you must include the Syncfusion library.

Additional Files for SQAPL

If your application uses the SQAPL/EL ODBC interface, you must distribute and install four additional components.

  • SQAPL INI
  • SQAPL ERR
  • SQAPL DLL
  • APLUNICD INI

For the names of the files corresponding to these components, see Files.

The SQAPL DLL must be installed in the user's Windows directory or be on the user's path.

Miscellaneous Other Files

DyaRes DLL

If your run-time application uses any of the bitmaps or other GUI resources that are built into the Dyalog Session, you must include the DyaRes DLL with your application.

AUXILIARY PROCESSORS

If you use any of the Auxiliary Processors (APs) included in the sub-directory xutils, you must include these with your application. Note that, like workspaces, Dyalog APL searches for APs using the WSPATH parameter. If your application uses APs, you must ensure that you specify WSPATH or that the default WSPATH is adequate for your application..

DYALOG32 and/or DYALOG64

This DLL is used by some of the functions provided in the QUADNA.DWS workspace. If you include any of these in your application this DLL must be installed in the user's Windows directory or be on the user's path.

Universal C Runtime DLLs

Under Windows, many of the Dyalog APL run-time components (.EXE and .DLL) are linked dynamically with the Microsoft Universal C Runtime library (the UCRT) which is supplied and installed as part of the normal Dyalog development installation.

At execution time it is important that the Dyalog runtime components bind with a version of the UCRT that is compatible with (that is, the same as or newer than) the one with which they were built.

Windows 10

If the end-user of the Dyalog application is known to be running Windows 10, the Dyalog application will pick up the system-wide UCRT which is part of Windows 10. There is therefore no need to include the UCRT with a Dyalog run-time application.

Other Versions of Windows

The UCRT is not supplied with versions of Windows prior to Windows 10. On these platforms, it is therefore necessary to install the UCRT as part of the installation of the Dyalog run-time application. There are two ways to achieve this which are referred to herein as the VCRedist installation and App-local installation. Dyalog recommends the former.

The VCRedist package, which includes the UCRT, is supplied with the Dyalog development package.

Simply copy the vc_redistx86.exe (32-bit version) or vc_redistx64.exe (64-bit version) program from the Dyalog development package into your own installation package and execute it as part of the installation of your Dyalog run-time application. This installs the UCRT into a shared Windows location; in effect the UCRT becomes part of the Windows system. The installation therefore requires Administrator privileges.

App-local Installation

An alternative is to install the UCRT components into the same directory as your Dyalog run-time application. There are two ways to obtain these files.

Either

Install the Dyalog development package (ideally onto a separate system just for this purpose) without administrator rights. This will perform an App-local installation of Dyalog itself. Then copy the UCRT files into your installation package. These files are:

  • those beginning with api-ms*
  • ucrtbase.dll
  • vcruntime140.dll

Or

Download and install the Windows 10 SDK from: https://developer.microsoft.com/en-us/windows/downloads/windows-10-sdk, and follow the instructions in the link below. https://blogs.msdn.microsoft.com/vcblog/2015/03/03/introducing-the-universal-crt

Finally, modify your installer to add these files to the same folder as your Dyalog run-time application.
