It\u2019s very similar to struct data type from other programming languages.<\/p>\n\n\n\n<p>It consists of one or multiple existing types into one new type. A good example of using this <a href=\"https:\/\/officetuts.net\/excel\/training\/vba-data-types\/\">data types<\/a> is a database record. If you want to keep a record of your employees, it\u2019s a good idea to use the <strong>Type<\/strong> structure.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">Type Employee\n    first_name As String\n    last_name As String\n    id_number As Integer\n    salary As Long\nEnd Type<\/pre>\n\n\n\n<p>A variable declared as Employee will have all these data types built-in. You declare user-defined types the same way you declare standard built-in VBA types.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">Dim emp As Employee<\/pre>\n\n\n\n<p>Now, you can access individual fields of this structure by using the dot (.) operator. You can assign a value to any of the Employee types.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">emp.first_name = \"John\"\nemp.last_name = \"Brown\"\nemp.id_number = 1\nemp.salary = 50000<\/pre>\n\n\n\n<p>Now, you can display these elements. In this example, we are going to do it inside MsgBox.<\/p>\n\n\n\n<p>In order to run this function, you have to create a new module inside the VBA editor (<strong>Left Alt + F11<\/strong>).<\/p>\n\n\n\n<p>Copy the following code into the module you created.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">Type Employee\n    first_name As String\n    last_name As String\n    id_number As Integer\n    salary As Long\nEnd Type\n\nSub CheckEmployee()\n    Dim emp As Employee\n    emp.first_name = \"John\"\n    emp.last_name = \"Brown\"\n    emp.id_number = 1\n    emp.salary = 50000\n    \n    MsgBox \"Employee \" + emp.first_name + \" \" + emp.last_name + \", identified by id \" + CStr(emp.id_number) + \" earns \" + CStr(emp.salary) + \" dollars a year.\"\nEnd Sub<\/pre>\n\n\n\n<p><strong>Code explanation<\/strong><\/p>\n\n\n\n<p>The code is pretty straightforward. What probably needs explanation is the <strong>Long<\/strong> type in salary and the&nbsp; <strong>Cstr<\/strong> function used in MsgBox.<\/p>\n\n\n\n<p>The <strong>Long<\/strong> type is used, instead of Int because we deal with big numbers.<\/p>\n\n\n\n<p>The <strong>Cstr<\/strong> function converts the numeral value into a string. Otherwise, the code will result in an error.<\/p>\n\n\n\n<p>This code will return the following result.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"389\" height=\"133\" src=\"https:\/\/officetuts.net\/excel\/wp-content\/uploads\/sites\/2\/2018\/11\/msx-box-data-type.png\" alt=\"\" class=\"wp-image-3511\" srcset=\"https:\/\/officetuts.net\/excel\/wp-content\/uploads\/sites\/2\/2018\/11\/msx-box-data-type.png 389w, https:\/\/officetuts.net\/excel\/wp-content\/uploads\/sites\/2\/2018\/11\/msx-box-data-type-300x103.png 300w\" sizes=\"(max-width: 389px) 100vw, 389px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>In VBA, you can create your own data types using the Type keyword.
