EMS.NotesResource Sample is a server-client EMS demo. It requires InterBase to be installed on the machine or to connect to a remote server. Make sure that the server is running before you run the sample. InterBase is used to store the information with the server connections. Use the RAD Server Console to display the statistics. The first part consists of creating an EMS Package with a new ResourceName (Notes). Once you run the package, the resource is registered on the EMS server and can be accessed by a client application using REST. The client needs a TEMSProvider to connect to the EMS Server and to retrieve the JSON data. How to Use the Sample Run the EMS Package When you run the NotesResourcePackage project, the EMSDevServer starts automatically. If the configuration file is missing, a wizard launches. Navigate to the location given above and open: Delphi: NotesResourcePackage.dpk C++: NotesResourcePackageCpp.cbproj Press Shift+Ctrl+F9 or choose Run > Run Without Debugging. The EMS Development Server opens. If it is the first time you are using EMS on the machine, you need to run the configuration wizard in order to create the EMS server configuration file. When the Confirm dialog opens, click Yes. Leave all the parameters by default and go through the different windows by clicking Next. Click Finish to close the wizard. An Information window appears. Click OK. The server starts automatically. Minimize it. Run the Client Application The client expects the EMSDevServer to be running at localhost:8080. If you are running the server at a different address, modify the properties of the TEMSProvider component. The Delphi supported platforms for this sample are: 32-bit, 64-bit Windows, and iOS Simulator. To run the sample on iOS Simulator, change the URLHost property of the TEMSProvider component to the IP address from the machine you are launching the sample and running the server.Note: The TEMSProvider component is placed in the NotesClientModule unit. The C++ Supported platforms for this sample are: 32-bit and 64-bit. On the Project Manager, right-click on ProjectGroup1. Click Add Existing Project…. Navigate to: Delphi: Start | Programs | Embarcadero RAD Studio Sydney | SamplesObject PascalDataBaseEMSNotesResourceNotesClientProject.dproj. C++: Start | Programs | Embarcadero RAD Studio Sydney | SamplesCPPDatabaseEMSNotesResourceNotesClientProjectCpp.cbproj. Press F9 or choose Run > Run. Insert a User name and Password and click Signup, or Login if you previously created an account. Click Add to add a new note. Write the note and click Save. Implementation EMS Package The Resource Module has code to register a REST OverView API resource. The resource is called “Notes”. The resource defines a Get, GetItem, Post, PutItem, and DeleteItem method. Once you run the package and have the EMS server running, as a test, you can invoke the GET method by using the browser http://localhost:8080/Notes.Note: An error message appears informing that you need to be logged in to access this information. The NotesStorageU file defines the path of the notes.ini file where the created notes are saved. Client Application The client application has a TEMSProvider component. This component identifies the address of the RAD Server Engine (EMS Server) (http://localhost:8080). The client application also has a TBackendEndPoint for each method. This component identifies the name of a resource (Notes), the method used, and the ResourceSuffix. The information is managed with TJSONObject and TJSONArray. You can find attached a link below with the original post: http://docwiki.embarcadero.com/CodeExamples/Sydney/en/EMS.NotesResource_Sample

Embarcadero Tech Partner WINSOFT provides an easy to use MAPI suite for Delphi. What makes MAPI hard? MAPI is hard. There is lack of clear and consistent coding, different answers provide different solutions, the solution is not in Delphi, there has to be various work-arounds, or the code-snipplet was built for very old non-Unicode version of Delphi. You eventually tear your hair out or get exasperated with partial or non-working solutions. C#, VB.NET users are left out in the cold: if you look around, using MAPI in C# is out of the question as you’ll get all kind of errors as, Extended MAPI is not supported for use with .NET MAPI is supported in native-languages, such as C++ Builder and Delphi. MAPI is an interface for, nearly all email clients on the Windows platform. TheBat – an independent email client, ThunderBird – the FireFox competitor to Outlook, HCL Lotus Notes (formerly IBM, formerly Lotus Notes) and Outlook.

FireDAC is a unique set of Universal Data Access Components for developing multi-device database applications for Delphi and C++Builder. With its powerful common architecture, FireDAC enables native high-speed direct access from Delphi to InterBase, SQLite, MySQL, SQL Server, Oracle, PostgreSQL, IBM DB2, SQL Anywhere, Access, Firebird, Informix and more. Large collection of advanced capabilities. Key things to know about FireDAC listed in this post. Configuration Options: Highly configurable, using this you can fine tune your data access and it is important how your Software access with databases. FireDAC provides a wide range of options organized into a hierarchical options system. Most of the options may be left with their default values.The FireDAC options are organized into five groups: FetchOptions – Fetch options that control how the components and Phys layer commands fetch data from a DBMS. For example, it is possible to fetch all records at once or fetch records on demand. FormatOptions – Format options that control how the DBMS data types are mapped to the FireDAC data types and backward. For example, a programmer may set up a mapping for Oracle NUMBER (38) onto dtBCD or onto dtInt64. For more details, read Data Type Mapping. UpdateOptions – Update options that control how FireDAC posts updates to DBMS. For example, during an update, FireDAC can update all fields in a table or only the changed ones. ResourceOptions – Resource options that control how system resources are used, dataset persistence and other. For example, a FireDAC Phys layer command can be performed asynchronously or blocked. TxOptions – Transaction options that control how transactions are performed. For example, perform them in a ReadCommitted isolation mode. Note that TxOptions does not use option value inheritance. SQL Command Preprocessor: The SQL command preprocessor can alter your SQL before sending it to the server When ResourceOptions.EscapeExpand and ResourceOptions.MacroExpand are true. It supports macros substitution and escape sequences.FireDAC supports three types of macro instructions: Substitution variables. A substitution variable starts with the ‘!’ or ‘&’ symbol and is followed by the macro variable name.They allow placing substitution parameters in a command text in order to extend the use of parameters. For example, to parameterize a table name in the FROM clause or the column names in the SELECT clause, you can use substitution variables but not parameters. Escape sequences. They allow writing DBMS-independent SQL commands. Conditional substitutions. They allow expanding the SQL command conditionally, depending on application-defined attributes or on the currently attached DBMS. FireDAC has 4 types of escape sequences: It is enclosed in curly braces ({}). Allowing constant substitution: Allow writing constants in command text, independent of the DBMS syntax and regional settings. Allowing identifier substitution. Alows abstracting from DBMS-specific identifier quoting rules.  Conditional substitution: Allow to substitute text into command, depending on either a DBMS the application is connected to, or on a macro variable value. Beside different syntaxes, these constructions handle parameters and macros in different ways. Scalar functions.Allows abstracting from a DBMS-specific set of a built-in functions and their syntax.  For examples check here Array DML : The Array DML execution technique submits a single DBMS command with an array of parameters. Each command parameter has an array of values, and all parameters have arrays of the same length. Then FireDAC requests the DBMS to execute a command once for each row in arrays. This technique reduces the amount of communication between DBMS […]

Surprised with the Title? Yes without knowledge of HTML, CSS, JavaScriptyou can build from Delphi/C++Builder your Web Front end using some of the Client/Server(FullStack) or Client-Focused third party web frameworks. Curious to know how these frameworks do this? This post will help you to understand. What does a web front end framework does exactly: Visual Layout Designed in IDE to render in the browser with HTML, JavaScript & CSS. Using Delphi or other visual designers to create a visual layout. No need to know HTML, CSS, or javascript, may allow customization through HTML, CSS, and JavaScript. No special client plugins required. Some create both server and client-side functionality. Some use pascal to Javascript Transpilers. Transpilers : Transcompiler(translating compiler) or source to source compiler Converts or Translates one programming language to another one. Usually, only a sunset or special dialect of the source language is supported. Platform-specific libraries not supported. Frequently used to convert high level, type-safe, languages into javascript. Examples: Typescript or CoffeeScript transpilers. Some of the Pascal to JavaScript Compilers listed Below : Commercial: OpenSource: C++ to Javascript ; Based on LLVM , Open Source, Compiles C++ to JavaScript. Visual Design Front End Frameworks : AtoZed Software’s IntraWeb: Runs into IDE creating both front end and backed end, Modeled on VCL, Visual Client Designer. The client built from the JS and HTML library. Delphi UI event handlers run on servers, extensible via typescript. Supported by Third Party like TMS Software. Thinfinity Virtual UI By CybeleSoft: Transforms you desktop application into a web application. Includes Javascript Remote Object (jsRO) framework. Full HTML 5 cross-browser client. Server redirects GDI/GDI+ calls to Javascript client. FMSoft UniGui: Installs into Delphi IDE, VCL like design and use. Provides data-aware controls, supports desktop and mobile. Allows optional javascript for client-side events and VCL like server event handlers. SMS (Emphasis on Node.js and cloud-based development) and Elevate Web Builder ( Emphasis on data-driven development) uses Delphi like IDE to design the UI and an Object Pascal to JavaScript transpiler to Create HTML, CSS, Javascript.
