This method gives us two parameters: objectProvider holds a serialized copy of the debugged object we wish to view, windowService allows us to show a dialog under the context of the IDE. Next, I overrode the protected method Show.
The customizable parameters are Target (the type to show the visualizer for) and Description.

I added the DebuggerVisualizer attribute to the assembly so that the Visual Studio IDE will know how to use this visualizer. I created a class library project, added a new class and inherited it from DialogDebuggerVisualizer (placed in the namespace). PictureBox pictureBox = new PictureBox() Image image = (Image)objectProvider.GetObject() įorm.Text = string.Format( " Width: ",įorm.ClientSize = new Size(image.Width, image.Height) įorm.FormBorderStyle = FormBorderStyle.FixedToolWindow IVisualizerObjectProvider objectProvider) Override protected void Show(IDialogVisualizerService windowService, Public class DebuggerSide : DialogDebuggerVisualizer

Using the codeīelow, you can see the entire code for my image debugger visualizer: You can place a breakpoint at any place in your algorithm and see what the image looks like at that time. This visualizer is extremely helpful for anyone writing an application that manipulates images. In this article, I will show how to create a debugger visualizer to view Image objects. It turns out that the Visual Studio team has made it really easy to add this functionality to other data types. Click that icon and you get a form showing the underlying data of the DataSet object. You get a tooltip with various information and a little icon with a magnifying glass. Try placing a breakpoint in an application with a DataSet object and hover your mouse over its variable. In accordance with their names, debugger visualizers allow you to visually view useful information about objects during debug. If (securityGuard.Visual Studio 2005 shipped with a very nice feature called debugger visualizers. New CardReader(display, keyPad, securityGuard) Call students to chairs as objects are instantiated and give them their object name on a piece of paper.Start with empty chairs and main() method.Put five empty chairs in a scattered, random sort of pattern.functions are the units of modularity, organization, and encapsulation within the program.several functions (get_pin, get_activity_selection) use the same hardware device (keypad).the order of execution and use of machine/program is determined by the way the code is written.global data is used by functions to avoid unwieldy passing of arguments.how the main method has transaction logic in it.how relatively important the main() method is lots of intelligence.Pass the koosh ball along to each function as they execute.Begin execution in main() showing the code for main() on the board.Stand yourself at the end of the line, with a whiteboard nearby.Label functions with pieces of paper students hold.Stand students in a line facing classroom (code layed out linearly in memory).
koosh ball – thread of execution (program counter).global data structures – desks or chairs.Notice how much like a computer network this topology looks.īlank paper, heavy marker pen Baseline Procedural Visualization for Comparison Acting out Inter-cluster messages exist, but are less common than intra-cluster messages. Objects cluster together by those which communicate most frequently. Modules are nested into a calling tree, as shown below:īy contrast, the topology of an OO program is inherently less ordered. The topology of a structure program is inherently different than the topology of an OO program. The intent is to give a more intuitive feeling for how an OO program looks in execution. The “design” of the program leaves many things unexplained and weird. The “code” is written in a sort of pseudo Java/C++. The ATM only lets a validated user do a single withdrawl or deposit, then returns the card. This demonstration uses a very simple ATM system to contrast the execution of a structure and an OO program. Other Object Oriented Class Relationships.Special thanks to Gilbert Benabou for taking to time to compile the first printable version of this document and inspiring us to provide it.
Some people still find them useful, so here they are, caveat emptor. It also represents a view of OO circa early to mid 1990s. This collection of notes on OOP was never meant to stand alone.
