Saving A Project

When you are saving the project it means two things. The first is that you save the changes made to the project. Second, before giving a meaningful name to the project, let me tell you how you name a project. Follow these steps to name a project.

  • Click File and select Save All or press Ctrl + Shift + S from the keyboard.
  • After this Save Project dialog box will open. The Save Project dialog box has three text boxes namely Name, Location, and Solution Name. In the Name text and Solution Name text boxes, you will see that WindowsApplication1 is written. In the Name text box, type the name of the project, which will also be the name of the solution. You can keep the project and solution names separate if you want. This happens when you are building an application that has more than one project.

Here you type the name in the Name that you want to name the project. In the Location text box, enter the location on your hard disk where this project will be saved. You can keep the default location or you can change the location by clicking Browse. If you want to create a separate directory for the solution, then leave the Create directory for the solution checked, which is a common and good practice. If you do not want to save your project and solution in any directory, then clear the Create directory for the solution check box.

  • Select File Save if you want to save the changes made to your project. Or

Then press Ctrl + S from the keyboard.

Difference between solution and project

A solution is a fundamental unit of Microsoft Visual Studio. When you create a project, it is a solution. You can know the solution as complete software. A solution can contain multiple projects and a project can contain multiple forms, classes, etc.

Open an Existing Project

Opening any previously created project is a very easy task. This is the same process we have been doing to open any file in MS Word. To open a created file, follow the following steps in sequence –

  • Open Visual Studio.
  • Click the File menu and select Open Project… or press Ctrl + 0 simultaneously from the keyboard.
  • After that Open Project dialog box will be displayed.

Now open your solution folder. It can contain many files and folders. Carefully open the Microsoft Visual Studio Solution file. There are many folders and two files. In this, the first file is the solution file and the second file is the project file. Opening any of these files will open your project. But if suppose there is more than one project inside the solution then it is safer to open the solution file itself. Double-click the solution file or select the file and click Open.

Apart from this, there is another way by which you can open your project. which is as follows.

  • Click File and point to Recent Projects… and click the desired project.
  • Select the required project from Recent Projects on the start page.

Both the above methods are limited to open recently created projects only.

Adding a form to a Project

You can add as many forms to the project as you need. Follow these steps to add a new form to the project –

  • Click on Project and select Add Windows Form
  • Thereafter Add New Item dialog box will appear on the screen.
  • Select the Windows Form option if it is not already selected.
  • Type the name in the Name textbox if you want to change its default name.

Finally, click on the OK button.
