Windows application in visual studio

Its strength is integrating tightly with the active development project, simplifying analysis of the most common performance scenarios, and quick, easy collection of only a single application. Windows Performance Toolkit is created by the Windows team for understanding system wide characteristics of the entire PC at once. While it grew up from the need to analyze hardware and drivers, it is very effective on understanding software problems as well.

Its strength is around gathering large quantities of information from the entire machine at once, so multi-process issues, those dealing with hardware or drivers, and complex scenarios are well-matched for these tools. There is overlap between the two tools. Often you can start exploring an issue in one tool and switch to the other for a different view of the same scenario.

Other times, one of the tools will be more effective than the other. The Visual Studio Performance Profiler is a component of Visual Studio itself and is installable through the same installation wizard as the rest of the development environment. However, the command-line Performance Recorder tool is pre-installed with Windows 10 and later as wpr. The Performance Analyzer is available as an application in the Microsoft Store. Windows Performance Toolkit additionally offers two extensibility points that can serve advanced performance analysis scenarios.

For performance analysis scenarios to work, you will need access to the symbols that correlate with the Windows application being tested. When building with Visual Studio, they will be located the same as in the debugging scenario settings , either built with your solution or captured from symbol servers. When analyzing other libraries or components, you will have to locate the symbols for those components to complete your analysis.

The tool to choose depends on the performance scenario that you are attempting to explore. A comparison of functionalities and traits among the two tools is in the table below:. For a general rule, start with Visual Studio Profiling when possible. Next comes the Label Control.

The label control is used to display a text or a message to the user on the form. The label control is normally used along with other controls. Common examples are wherein a label is added along with the textbox control. The label indicates to the user on what is expected to fill up in the textbox.

Step 1 The first step is to drag the label control on to the Windows Form from the toolbox as shown below. Step 2 Once the label has been added, go to the properties window by clicking on the label control.

In the properties window, go to the Text property of each label control. A textbox is used for allowing a user to enter some text on the Windows application in C.

We will add 2 textboxes to the form, one for the Name and the other for the address to be entered for the user. Step 1 The first step is to drag the textbox control onto the Windows Form from the toolbox as shown below.

Step 2 Once the text boxes have been added, go to the properties window by clicking on the textbox control. In the properties window, go to the Name property and add a meaningful name to each textbox. For example, name the textbox for the user as txtName and that for the address as txtAddress.

A naming convention and standard should be made for controls because it becomes easier to add extra functionality to these controls, which we will see later on.

A Listbox is used to showcase a list of items on the Windows form. We will add a list box to the form to store some city locations. Step 1 The first step is to drag the list box control onto the Windows Form from the toolbox as shown below. Step 2 Once the list box has been added, go to the properties window by clicking on the list box control. In the output, you can see that the Listbox was added to the form.

You can also see that the list box has been populated with the city values. A Radiobutton is used to showcase a list of items out of which the user can choose one. Step 2 Once the Radiobutton has been added, go to the properties window by clicking on the Radiobutton control. A checkbox is used to provide a list of options in which the user can choose multiple choices. We will add 2 checkboxes to our Windows forms. These checkboxes will provide an option to the user on whether they want to learn C or ASP.

To handle the messages, we first add a message loop to listen for the messages that Windows sends. When the application receives a message, this loop dispatches it to your WndProc function to be handled. The message loop resembles the following code. To enable the WndProc function to handle the messages that the application receives, implement a switch statement. The event can occur when a user moves a window in front of your window, then moves it away again.

Your application doesn't know when these events occur. When the window is first displayed, all of it must be updated. For the application, the logic between the beginning call and the ending call displays the string "Hello, Windows desktop!

In the following code, the TextOut function is used to display the string. HDC in the code is a handle to a device context, which is used to draw in the window's client area. Use the BeginPaint and EndPaint functions to prepare for and complete the drawing in the client area. BeginPaint returns a handle to the display device context used for drawing in the client area; EndPaint ends the paint request and releases the device context.

An application typically handles many other messages. The following code shows a basic but complete WndProc function. Delete any code you've entered in HelloWindowsDesktop. Copy this example code and then paste it into HelloWindowsDesktop. On the Build menu, choose Build Solution. The results of the compilation should appear in the Output window in Visual Studio.

To run the application, press F5. A window that contains the text "Hello, Windows desktop! You've completed this walkthrough and built a traditional Windows desktop application. Windows Desktop Applications. Skip to main content. This browser is no longer supported.
