Transflo DMS Enterprise Client API

This older KB article provides sample code and requirements to connect, upload, and retrieve documents from the TRANSFLO® Server using the Classic Transflo DMS Client API. TRANSFLO Client API is a set of libraries that have various methods to import and extract batches of documents to and from the TRANSFLO® System. The TRANSFLO® Client objects are available as COM libraries or as .NET 4.0 assemblies.

Tip: In order to invoke TRANSFLO® Functionality from other languages and platforms, you must use the TRANSFLO® Web Service API. See Transflo DMS Web Service API.

 

The TRANSFLO® Client API consists of the following libraries and dependent libraries:

  • Transflo.dll

  • Transflo.Client.dll

  • Transflo.Shared.dll

  • NZipLib.TF.dll

  • Microsoft.Web.Services3.dll

The Client Configuration application consists of the Client API libraries and the following items:

  • Transflo.ClientConfig.exe

  • Transflo.Components.dll

  • Transflo.Forms.dll

Note: Any assembly you create to interact with the TRANSFLO® Client API must be a .NET 4.0 assembly.

Before using the TRANSFLO® Client API, follow these steps to set up the environment:

  1. If you are using the COM interface, register TRANSFLO® Client API DLL files for COM.

    The syntax for registering the COM components in a Windows command prompt is:

    %SystemRoot%\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe Transflo.dll /codebase

    %SystemRoot%\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe Transflo.Client.dll /codebase

  2. Open the TRANSFLO® Client Configuration application and enter the TRANSFLO® Web Service URL.

  3. Click the Validate button.

  4. Once a valid URL is configured click OK.

This section describes the basic steps for programming with the TRANSFLO® Client Interface API.

  1. Connect to the TRANSFLO® Server.

  2. Get and update latest configuration.

  3. Create a batch of documents.

  4. Assign metadata to the batch.

  5. Submit the batch to the TRANSFLO® Server.

  6. Get a batch and modify it.

  7. Submit a batch to the repository.

  8. Log out and end session.

The following table lists the supported exposed repository objects of the Transflo Client API:

Object

Properties

Methods

Document

A representation of a Transflo repository document.

  • string UserName;

  • byte[] Bytes;

  • bool EmptyBytes;

  • string DocumentId;

  • string FileName;

  • string FileType;

  • int FieldCount;

  • int AnnotationCount;

  • string DocClassName;

  • DocumentCommand[] Commands;

  • DateTime InsertDateTime;

  • DocumentField FindField(string fieldName);

  • DocumentField GetField(int fieldIndex);

  • Annotation GetAnnotation(int annotationIndex);

  • void AddField(string fieldName, string fieldValue);

  • string GetDocumentTypeList(string docClassName, string fieldToCount, string keyFieldNameValuePairList);

  • string DocumentsCountExists(string docClassName, string keyNameValuePairList, string expectedDocTypeCountList);

  • Document[] GetRepositoryDocumentsData(string docClassName, string keyFields, RepositoryDocumentOptions documentOptionsToInclude);

  • Document[] GetRepositoryDocumentsData(string docClassName, string keyFields, RepositoryDocumentOptions documentOptionsToInclude, DateTime fromDate, DateTime toDate);

  • StringCollection GetDocClassNameList();

  • StringCollection GetDocClassFieldNames(string docClassName);

  • void SaveRepositoryDocument (Document document);

  • void SaveRepositoryDocuments(Document[] documents);

The Repository API is used to interact with documents that have been saved in the configured permanent repository. These functions work for all supported repositories and return the same type of data. The supported repositories are TRANSFLO® and OpenText Gauss. All references in this section to the term document refer to the repository document class In Transflo DMS, a document class (DocClass) is a defined set of document types and associated fields. A Transflo document class has built-in security and is a good way to separate types of documents by department where document data is sensitive in nature, such as documents for human resource personnel records, taxes, billing, security, military, or government data..

In August 2023, a Web API enhancement [152279] was implemented to improve API support for Gauss repositories.

The repository document class Transflo.Bridge.Repository.Document is the basic document object type returned by GetRepository DocumentsData( ) and other methods.

Example

The example in this section is written in Microsoft C# programming language. A C# demo application is included with this API documentation in the scripts.zip file in the Transflo Client API Demo folder. To use the demo application:

  1. Install the TRANSFLO® Standalone Client Component. (This is shipped with the TRANSFLO® Installers.)

    Execute step 1 only if you do not have the TRANSFLO® Client application already installed, or if the intention of the API usage will be in a box with no TRANSFLO® Client application at all.

  2. Run the Client Config at the end of the installation and configure the URL for the TRANSFLO® server you plan to use and validate.

  3. Create a folder on your hard drive.

  4. Unzip the demo application from the scrips.zip file and copy the Transflo Client API Demofolder into the folder you created in the previous step.

  5. Load the included solution, build the demo app, and run it.

  6. If one or more references to any assemblies fail, re-add them from the folder where the client was installed. The default location is:

    C:\Program Files (x86)\Common Files\Pegasus TransTech\Transflo Client

Aliases are used by Capture and Batch Scan. During imports, aliases map Gauss bases to workflows. By default, each document class that you create is automatically assigned an alias of the same name. You can edit the name and create more aliases. You can use an alias to configure fields, document types, and other parameters to customize the Capture application. for the session.
