Process Purpose

 

The "Checksum" process is used to compute the checksum of the intended value. The result is stored in a variable.

Check the provided "Checksum" examples at the end of the topic.

 

 

When you add a process, you are required to define its settings. This occurs in the process's properties window which is displayed automatically after having added the "Checksum" process.

If any subsequent edition is required, double-click the process to open its properties window and enter the necessary modifications.

 

 

Fill in the following options:

 

Mathematic Compute a Checksum

Source Variable

Click to select the variable with the string to have its checksum calculated. See Variable Usage.

Type of Checksum

Select the type of checksum from the drop down (“XOR”; “CRC16“; “CRC32”; “SHA” or “MD5”).

Store Result into Variable

Click to define the variable that will receive the result checksum value. See To Select/Create a Variable.

 

If required, click (on the upper right corner) and enter info about this process in the resulting text box. These notes will be displayed in the corresponding "Actions" tab or "Process" window (in the "Notes" field) and in the "Developer Report".

 

After filling in the required options, click to conclude or to abort the operation.

 

The added process is displayed in the corresponding "Actions" tab or "Process" window.

 

 

Use the right-click in MCL-Designer's input boxes to access some related options as well as the general "Cut", "Copy"; "Paste"; "Search" actions (active/inactive according to the current context).

Ex: If you right-click the "Variable" input box (included in a "Conversion's" properties window), you are provided with general editing/search actions and other more specific options such as "Variable Select" (see "Variable Select"); "Variable Insert" (see "Variable Insert"); "Insert Special Character" (see To Insert Special Characters into a Control's Text Input Field) and "Localization Select" (see Localization List).

If you right-click another input box, it may provide other possibilities.
