<\/p>\nIn this tutorial we will be looking at some of the more common, easy to use controls\/functions of VB. We are going to create a simple form and update it using other information that is provided by the user. When making forms it is a good practice to name all of the controls and labels on the form in a manner in which you can remember. This will allow for easy debugging if something were to go wrong and\/or needs to have a code change made. For example, I typically take the word that the command is like such as a button and turn it into a three letter acronym such as BTN. This way when scrolling through all of my objects I can automatically go to all of my buttons. Personally, I start all of my buttons with CMD as they generally \u201ccommand\u201d things to happen. So If I had a login form, everything would be named as shown below :<\/p>\n
<\/p>\n
As you can see my Text Boxes are name txtXXXXX, my Form is name frmMain, my Buttons are named cmdXXXXX and my Labels are named lblXXXXX. This is not 100% necessary but it will make life easier once you start getting into hundreds and then thousands of lines of code. <\/p>\n
To start, the screen shot below shows the properties windows when a button is selcted.<\/p>\n
<\/p>\n
All of the things listed in the column above can be modified during run time. By this, I mean that the configuration of the button can be changed using code after a certain event happens, for example: by clicking on a button we can change the text of a label to the contents of a text box that we have on the form. To call these features, you type the name of the control (ex. cmdExit) and then a period and type the name of the property you want to change. This brings us to our first form that we are going to create. Create the form as shown below: (for the sake of the tutorial, I am making two pictures, one that uses the \u201ctext field\u201d to show the name of all the items on the form so that you can name yours the same way so the code will work, and the second to show what that actual \u201ctext field\u201d of the item is.)<\/p>\n
<\/p>\n
One you have everything named, we need to start adding our code. To start, double-click on the Exit button. It will automatically open your code viewer\/editor and add the Sub Name and End Sub commands. Whatever you type between these fields will be run every time the exit button is clicked. The command for and Exit button is usually simple. Just type \u201cEnd\u201d. You should see this:<\/p>\n
