Overview

 

Within MCL-Designer V4, it is possible to use aliases to refer locations (paths). In other words, instead of using an absolute path to locate a file, you can use a relative path (which includes an alias) to facilitate file/folder access.

 

MCL Alias List

 

Alias

Relative path

Absolute path

<MCL>

-

Path to the MCL folder where MCL components are installed (depends on device model and OS).

<APPS>

<MCL>\Apps

MCL\Apps

<DEFAULT>

<MCL>\Apps\"running application"

MCL\Apps\"running application"

<DATA>

<DEFAULT>\Data or .\data

MCL\Apps\"running application"\data

<RES>

<DEFAULT>\Res or .\res

MCL\Apps\"running application"\res

<SHARED>

<MCL>\Shared

MCL\Shared

<FILEBOX>

<MCL>\Filebox

MCL\Filebox

 

 

When entering a path, start with a backlash. This ensures project compatibility with the Windows Mobile/Windows CE and Android devices (ex: "\MCL\Apps\"running application" or "\MCL\Shared").

 

 

MCL Alias Usage

 

Below are examples of "Resource" files (see Navigating the Resources Module) and "Data Files" (see How to Work with Data Files) being referenced with the use of relative paths.

 

 

 

In a "Button" object:

The path to the resource's location ("banana.png") is referred with a relative path.

In an "Advanced List Box" object:

The path to the four resources used in the object is referred with a relative path (the alias <RES> represents the "Resources folder).

 

 

 

 

 

 

In a "Copy File" process:

The source file to be copied ("Inv.dat" in the Data folder) is referred with a relative path and so is the target (the MCL-Mobility Platform's Outbox area).

In a "Receive File from Host" process:

The target for the file ("list.txt") is referred with the use of an alias.

 

 

 

 

 

 

In a "Variable Combine" process that creates a new variable by combining/extracting data from variables:

The path to the Resources area is referred with an alias (.\res\).

In a "Read from INI File" process:

The path of the file to be read ("settings.ini") is referred with an alias (the "SHARED" folder).
