Creating Your First Program in Visual Basic

This instructable will show you how to program Microsoft Visual Basic 2005 Express Edition. The example that you will create today is a simple image viewer.

If you like this instructable please push the + button at the top of the instructable. Thanks.

Also, I think I will be like half the other instructables out there and say that this is my first instructable and please don't be to harsh.

EDIT: Once you have completed this instructable, continue learning VB with my second Visual Basic Instructable: Creating a Program in Visual Basic: Web Browser

You can download visual basic 2008 from microsoft but this instructable is specificly for VB 2005 wich you can download from freeware files

EDIT: It is now recommended you VB 2008, as I will use it for any future tutorials. Link

Please note: you will still need to be connected to the internet during the install.

Click File->New Project. Select "Windows Application". Give your project a name.

From the tools box, drag a picture box onto your form, drag a button onto your form and drag an open file dialog onto your form.

Now it's time to edit the properties of the controls. To edit properties, click on the object and change the values in the properties window.

Form Properties

• Text: Picture Viewer
• Form Border Style: Fixed Tool Window

Picture Box

• Background Image Layout: Zoom

Button

• Text: Select Image

Double click on the button and replace all the text in the code window with the following:

Begin Code

Public Class Form1    Private pic As Bitmap    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click        OpenFileDialog1.FileName = "Select File"        OpenFileDialog1.ShowDialog()        pic = New Bitmap(OpenFileDialog1.FileName)        PictureBox1.BackgroundImage = pic    End SubEnd Class

End Code

WHAT THE CODE DOES

Public Class Form1 - Defines the form as Public
Private pic As Bitmap - Defines pic As a private bitmap

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click - Defines When The Events Should Occur
OpenFileDialog1.FileName = "Select File" - Makes the file name in the OpenFileDialog say Select File
OpenFileDialog1.ShowDialog() - Shows the OpenFileDialog
pic = New Bitmap(OpenFileDialog1.FileName) - Adds the value of the selected image to pic
PictureBox1.BackgroundImage = pic - Changes the image in ImageBox1 to pic

End Sub

End Class

Save your program (File->Save All) and click the green play button on the toolbar to debug your program. If all goes well then you should be able to use the program.

The final program is stored in 'My Documents/Visual Studio 2005/Projects/PROJECT NAME/PROJECT NAME/Bin/Debug/PROJECT NAME.exe'
(Where PROJECT NAME is the name of the project)

That's it!
Congratulations on creating your very first program in visual basic. It wasn't so hard now - was it?

Now you can go onto making more complex programs, or you can edit this one. I made some modifications to my program:

• I changed the background color
• I added some copyright info

In fact - here is some homework for you: see if you can get the program to change size for the image

• HINT: You do it using the properties window.

Good Luck!
