This article demonstrates how we can create a simple image gallery in vb. In this article we create a usercontrol for doing it, our control will create thumbnails of the images from the specified directory or folder.

Steps: 1. Add a windows form named Form1. Add another Tooltip control by double click on ToolTip in toolbox or you can add by drag and drop 6.

For making this usercontrol we use the picture box control, In above control we create dynamic Picturebox controls for each image. We find all image type files with. DirectoryInfo class. How to use this control 1. Build your project. Just drag and drop in your form. Set its property Directorypath. Suppose you place this control on the form named Form1, then you can set its property Directorypath with the help of folderbrowserDialoog i am using textbox and button control to set the value of the Directorypath property with the help of FolderBrowserDialog control.

You can use another method for setting the Directorypath property value :. Skip to content. Image Gallery in vb. ObjectByVal e As System. EventArgs Handles MyBase. Fixed3D Me. Add Pic1 Pic1.

SelectedPath TextBox1.Program also provides options to stretch and shrink them, rotate at different angles through all axes and save them in different formats.

This example uses menus, radio buttons, group boxes, open and save dialog boxes, picture box and status bar controls. To compile and execute code with VS. NET, create a Windows application and copy and paste this code in Form1.

You learn how to use the Windows Forms Designer to drag controls like buttons and picture boxes on to your form, set their properties, and use containers to smoothly resize the form. You also get started writing code.

Step 2: Run your picture viewer app. Step 3: Set your form properties. Step 4: Lay out your form with a TableLayoutPanel control. Step 5: Add controls to your form. Add controls, such as a PictureBox control and a CheckBox control, to your form.The control displays the previous and next images in the file along with the current image. Introduction: This article discusses the construction of an image viewer user control that may be used to display images from a directory containing a collection of image files.

The current image may be opened from the user control into the default image application on the user's machine based upon that machine's file associations.

Image thumbnails are used to supply the previous, current, and next images from the directory. As shown in the demonstration, the user control could be added to an application where you might need to allow users to preview or visually scan images prior to opening them up for viewing or edit. There are two project contained in the solution.

ImageViewerVB is the first project and it is control library project containing a single user control. The second project TestImageViewerVB is a test application which displays a single form used to contain the user control. The Image Viewer user control contains everything necessary to browse to the image folder and to view the current, next, and previous images.

The control itself contains a text box and browse button used to open a folder browser dialog box; when the user navigates to the desired folder and selects it, the path the folder will be shown in the textbox control and the browse button click event handler will trigger the collection of all of the image files contained in the selected folder and will start up the display of the images.

The control contains three picture boxes used to display the previous, current, and next images. The previous and next images are accompanied by two buttons used to move backwards and forwards through the image collection. The paths to each of the image files are contained in an array list and an integer value with class scope is used to maintain the current position within that array list. If you'd care to open the code view up in the IDE you will see that the code file begins with the following using statements; most included are per the default configuration but System.

IO was added to support the directory operations used within the code: Imports System. IO Imports System. Collections Following the imports, the class is defined and a constructor added as are a collection of local member variables used to maintain the folder path, the image file paths in an array listthe image list position, and the images themselves previous, current, and next.

I'm not doing anything in the constructor here but you want to; for example, you might want to point the folder browser dialog to a default folder location. Public Class ImageViewer. Private mFolder As String. Private mImagePosition As Integer. Private mPreviousImage As Image. Private mCurrentImage As Image. Private mNextImage As Image. Public Sub New. End Sub Next up is the user control's load event handler; this demonstration does not do anything in the load event but you may wish to use this handler to do something here.

Object, ByVal e As. EventArgs Handles MyBase. End Sub The next section of the code is the browse button click event handler. In this section of the code, the handler opens the folder browser dialog box which the user may then use to set the path to the image folder. Once the folder has been set, the handler loops through that folder and locates all bitmap, jpeg, and gif files; the file paths any image files found are added to an array list bitmaps, gifs, and jpegs. Once the array list is populated with the files paths, the click event handler wraps up but setting the list index position to zero and then it calls the SetImages method which sets up the current, previous, and next images into the appropriate picture box.

The code is annotated and should be easy enough to follow:. Object, ByVal e As System. EventArgs Handles btnBrowse.

OK Then. If Not String. End If. Dim f As FileInfo.Steps of Creation: Step 1: First we want to create a form with a button to laod the given image, a listbox to contain each loadable image from the given directory and a picturebox with the background image format set to zoom to display the given image correctly.

Step 2: Next we want to create a defaultPath to load images from as well as load the image files on form load open program.

Step 3: Now we want to simply load the selected image file. We want to create an image variable with the default path and selected image file from the listbox file name and extension and set the pictureboxes background image to the created variable of image.

This question is for testing whether or not you are a human visitor and to prevent automated spam submissions.I wanted to be able to zoom in, zoom out, rotate my images and best of all, not have to scale my images down to make it fit inside my forms.

The DrawEngine is responsible for storing a bitmap in memory with the exact size of the panel.

It will be used to render the image in memory and draw it to the panel. The DrawEngine will recreate the memory bitmap on resizes to keep the height and width equal to the panel. The DrawObject has all the actual functionality of the Viewer. It is responsible for storing the original image in memory, Zooming, Rotation, Dragging and Jumping to the origin The position clicked on the Preview panel. These functions are called by events triggered inside of the KpImageViewer class.

As an example, see a snippet of the mouse functions. These are responsible for the dragging and selection of the image:. It is programmed to make sure the Image is never leaving the top left corner X: 0, Y: 0.

The main issue I had here is that as soon as you drag around your Image that you don't want the X or Y coordinates to become higher than zero.

This in itself is no issue but it comes up as soon as you start looking at the. This would mean that the minimum X value would be to avoid getting a floating image on the right side.
