Graphic Controls are new graphic-controls for Visual Studio. They are basic controls and can be modified in several ways to match the outfit you want. Most of the Controls fire the paint-event. This allows adding scales, text, markers or everything else you need. The underlying textures also can be modified or changed. The stored selection of images provides many opportunities. It is also possible to set the corresponding image directly. In this case you are not limited by the imagelist (256×256
Visual Studio 2022 is the best Visual Studio ever. Our first 64-bit IDE makes it easier to work with even bigger projects and more complex workloads. The stuff you do every day—like typing code and switching branches—feels more fluid more responsive. And out-of-memory errors? They’re about to be a distant memory.
CodeLens helps you easily find important insights, like what changes have been made, what those changes did, and whether you’ve run unit testing on your method. Essential information—like references, authors, tests, and commit history—is right there to guide you toward the best and most informed decisions about your work.
In this series of three tutorials, you’ll create a Windows Forms application that loads a picture and displays it. The Visual Studio Integrated Design Environment (IDE) provides the tools you need to create the app. To learn more, see Welcome to the Visual Studio IDE.
This program has a picture box, a checkbox, and several buttons, which you use to control the application. This tutorial shows you how to add these controls.
In this second tutorial, you learn how to:
In this section you’ll prepare to use Graphics Diagnostics for the first time, then you’ll capture frames from a Direct3D app and examine them in the Graphics Analyzer.
To use Graphics Diagnostics in Visual Studio, you must use Visual Studio Enterprise, Visual Studio Professional, or Visual Studio Community. Other editions, including Visual Studio Code, do not contain this feature.
Download Visual Studio Community or compare Visual Studio editions
The optional Windows feature Graphics Tools provides the capture and playback infrastructure that’s required by Graphics Diagnostics on Windows 10 and later.
For information on installing Graphics Tools, see Install Graphics Tools for Windows 10 and later.
1 Slide 1 VB Graphics Controls & Timer Control
2 Slide 2 Default Controls
3 Slide 3 Graphics File Formats used with VB
4 Slide 4 Using Images v At design time: Select a image thru the Picture property (form, Picture box or Image Box) v At Runtime: Form1.Picture = LoadPicture(“C:\MYPIC.BMP”) Image1.Picture = LoadPicture(“D:\PAMELA.JPG”) Picture1.Picture = image1.Picture Picture1.Picture = LoadPicture(“”) v Passing an empty string to the LoadPicture function clears the current picture.
5 Slide 5 Using Images with Forms v At design time: Select a form background image thru the Picture property v At Runtime: Form1.Picture = LoadPicture(“C:\MYPIC.BMP”) v picture that is placed directly on a form. If you want the picture to be a different size, you need to resize the original graphic file using a graphics utility.
6 Slide 6 Using Images with Forms v Placing the picture directly on the form have several drawbacks: –You cannot hide the picture; it can only be loaded or unloaded. –You cannot control the placement of the picture on the form. –You can place only one picture at a time on the form. –You cannot resize the picture. It’s placed on the form in its original (saved) size. v You can overcome these drawbacks by using the Picture or Image control.
7 Slide 7 Image Control v Provides a frame for the picture, allowing you to position it anywhere on the form. v Pictures can be resized. v Stretch property: –False (the default): the Image control is automatically resized to fit the picture you assign to it. –True: the picture is automatically resized so that the entire picture fits within the current boundaries of the Image control.
8 Slide 8 PictureBox Control v Although the PictureBox control uses more system resources than the Image control, it has some added features: –Can be used as a container for other controls –Drawing methods (for example, Line and Print) can be used to draw on the picture box v PictureBox does not allow resizing of the picture v Setting AutoSize property to True cause the PictureBox control to resize itself to fit the current picture.
9 Slide 9 The Timer Control v Executes code (in its Timer event) when the interval is complete. v Counts down repeatedly, as long as the Enabled property is set to True. v Designed to work with very small amounts of time; the maximum setting is just a little longer than a minute. v Uses: scheduling and performing repeated operations.
10 Slide 10 Setting Up the Timer v First draw it on the form, it does not show up at all while your program is running. v Place code in the Timer event and then set the following properties, either at designtime or runtime: –Set the Interval property. –Set the Enabled property to True. The Interval property can be set to any value between zero and 65,535.
11 Slide 11 The Timer Control v The Enabled property acts like a switch that turns your timer on and off. If the Timer control is enabled, the code in the Timer event is executed at the end of the time specified in the Interval property. v The Interval property can be set to any value between zero (disables the Timer control) and 65,535 milliseconds. v 10 seconds = 10,000 milliseconds.
12 Slide 12 Creating a Simple Animation Following is an example of using the timer control for a simple animation. Set the Interval property to 200 and the Enabled property to True.
The Windows Forms Designer provides many tools for building Windows Forms applications. This article illustrates how to build an app using the various tools provided by the designer, including the following tasks:
When you’re finished, you’ll have a custom control that’s been assembled using many of the layout features available in the Windows Forms Designer. This control implements the user interface (UI) for a simple calculator. The following image shows the general layout of the calculator control:
This Wrox Blox shows you how to add graphics to Visual Basic 2008 applications by explaining fundamental graphics techniques such as: drawing shapes with different colors and line styles; filling areas with colors, gradients, and patterns; drawing text that is properly aligned, sized, and clipped exactly where you want it; manipulating images and saving results in bitmap, JPEG, and other types of files. Also covered are instructions for how to greatly increase your graphics capabilities using transformations, which allow you to move, stretch, or rotate graphics. They also let you work in coordinate systems that make sense for your application. The author also describes techniques for using the above in printouts, describing the sequence of events that produce a printout and show how to generate and preview printouts, with examples which show how to wrap long chunks of text across multiple pages, if necessary.
In addition, you will learn about two powerful new graphic tools that were introduced with .NET Framework 3.0: WPF graphics and FlowDocuments. XAML graphic commands allow a WPF application to draw and fill the same kinds of shapes that a program can draw by using graphics objects.
