Resource File Vb Net Tutorial Visual Basic Update The UI

When a file is opened for reading or writing, it becomes a stream.

There are two main streams: the input stream and the output stream.

The input stream is used for reading data from file (read operation) and the output stream is used for writing into the file (write operation).

Dim f1 As FileStream New FileStream(sample.txt, FileMode.OpenOrCreate, FileAccess.ReadWrite).

The StreamReader and StreamWriter classes help to accomplish it.

The BinaryReader and BinaryWriter classes help to accomplish this.

For a Microsoft Visual Basic 6.0 version of this article, see 183638.

The WriteLine method writes a complete line of text to the text file.

Update UI from different tasks.

To explore further the subject, well see now a more demanding example, in terms of resources needed.

In this case, well make a program that will process simultaneously many text files, to update the UI to show what a single thread is doing in a given moment.

Provides properties and classes for accessing the applications resources.

Remarks The My.Resources object provides access to the applications resources and lets you dynamically retrieve resources for your application.

For more information, see Managing Application Resources (.NET).

The My.Resources object exposes only global resources.

It does not provide access to resource files associated with forms.

You must access the form resources from the form.

You can access the applications culture-specific resource files from the My.Resources object.

By default, the My.Resources object looks up resources from the resource file that matches the culture in the UICulture property.

However, you can override this behavior and specify a particular culture to use for the resources.

Properties The properties of the My.Resources object provide read-only access to your applications resources.

Name. You can also add or remove resource files by selecting your project in Solution Explorer and clicking Add New Item or Add Existing Item from the Project menu.

You can access resources added in this manner by using My.Resources.

FileName. resourceName.

Each resource has a name, category, and value, and these resource settings determine how the property to access the resource appears in the My.Resources object.

For resources added in the Project Designer: The name determines the name of the property, The resource data is the value of the property, The category determines the type of the property: Category Property data type Strings String Images Bitmap Icons Icon Audio UnmanagedMemoryStream The UnmanagedMemoryStream class derives from the Stream class, so it can be used with methods that take streams, such as the Play method.

Files - String for text files.

Bitmap for image files.

Icon for icon files.

UnmanagedMemoryStream for sound files.

Other Determined by the information in the designers Type column.

Classes The My.Resources object exposes each resource file as a class with shared properties.

As described in the previous section, the resources in a resource file are exposed as properties in the class.

Example This example sets the title of a form to the string resource named Form1Title in the application resource file.

For the example to work, the application must have a string named Form1Title in its resource file.

Example This example sets the icon of the form to the icon named Form1Icon that is stored in the applications resource file.

For the example to work, the application must have an icon named Form1Icon in its resource file.

Example This example sets the background image of a form to the image resource named Form1Background, which is in the application resource file.

For this example to work, the application must have an image resource named Form1Background in its resource file.

Example This example plays the sound that is stored as an audio resource named Form1Greeting in the applications resource file.

For the example to work, the application must have an audio resource named Form1Greeting in its resource file.

The My.Computer.Audio.Play method is available only for Windows Forms applications.
