There is an option to write information to a log file. This walkthrough uses members of the My. FileSystem Objectwhich are available in Visual Basic. See FileSystem for more information. At the end of the walkthrough, an equivalent example is provided that uses classes from the System. IO namespace. Your computer might show different names or locations for some of the Visual Studio user interface elements in the following instructions.
The Visual Studio edition that you have and the settings that you use determine these elements. For more information, see Personalizing the IDE.

The FolderBrowserDialog1. ShowDialog call opens the Browse For Folder dialog box. After the user clicks OKthe SelectedPath property is sent as an argument to the ListFiles method, which is added in the next step. The GetFiles method then retrieves a collection of strings, one for each file in the directory. The GetFiles method accepts a search pattern argument to retrieve files that match a particular pattern.
In this example, only files that have the extension. The strings that are returned by the GetFiles method are then added to the ListBox. Run the application. Click the Browse button. In the Browse For Folder dialog box, browse to a folder that contains.

Being a programming teacher also helps because I get a lot of questions from students, and it is always a joy; OK, more like a challenge to work out a simple project based on their questions.
Today, I will cover one of the most popular questions in my classroom, as well as on the forums. The topic of today is how to create an application similar to Windows Explorer.
Just a note, this program used to be an FAQ on CodeGuru forumsbut it is over six years old already and it is indeed time for a proper facelift and proper explanation on the logic involved. Put the following controls with their Properties on your Form:. Because we are working with the file system here, we need to include our System.
IO namespace:. This sub obtains all the sub folders inside the supplied path.
It then iterates through them and adds it to the TreeView. This tag will actually represent each sub folder name, which we could use to obtain all the files inside the particular folder.
We now need to make use of the TreeView's BeforeExpand method to get the subfolders of the selected folder inside the treeview:. We clear all the previous nodes, and add all the subfolders of the selected TreeView folder via the AddAllFolders sub. The final piece of the puzzle for our folders is to add the initial starting node for our TreeView. This should be the drive you want to browse through. We Sort the TreeView alphabetically and add the main node to it.
In this case it is Drive C:. If you were to run your project now, you'd be able to load all folders and their subfolders into the Treeview. Now, we need to obtain all the files inside the folders. Because we need a list of the files present in the selected folder, the most obvious place to get them is inside the TreeView's AfterSelect method.
This event happens when a selection was made in the TreeView. Let us add it now:. We obtain the folder name, and ensure that it does in fact exist.January 16, 8 Comments.
A stream is an abstraction which either produces or consumes information. Alternatively, we can say that streams represent a sequence of bytes going to or coming from a storage medium such as a file or a physical or virtual device network port or inter-process communication pipe. All streams behave in the same manner, even if the actual devices they are linked to may differ, which means we are going to use the same methods to write data to a standard output device as a disk file.
Using the ASCII character set it is easy to convert between char and byte by just ignoring the higher order byte. To overcome this problem. NET defines several classes that convert a byte stream to character stream, where handling of translation of byte-to-char and char-to-byte is automatic.
Before performing any operations through streams we can test for its support using CanReadCanSeekCanWrite methods. We can also use the other properties as Length and Position for knowing the length and pointer position respectively. When the file output is performed, data is often not immediately written to the actual physical device. If we can cause data to be written to the physical device whether the buffer is full or not we call the Flush method, and this improves efficiency.
Similarly, when we finished up writing to an output destination we should close the stream by using Close which ensures data preset in buffer written to the physical device. To create a character stream we use the. NET character stream wrappers which wrap a byte stream within themselves. The abstract classes in this category are TextReader and TextWriter. FileStream : To create a byte stream linked to a file we use the file stream class.
We can perform both read and write operations using this class. The BinaryReader and BinaryWriter classes are suitable for working with binary streams; one such stream might be associated with a file containing data in a native format. The data is read and written using its internal binary format, not its human readable text format. We must create a Stream object explicitly and pass it to the constructor method of either the BinaryReader or the BinaryWriter class.
These classes provide a wrapper around the byte stream which manages the reading and writing of binary data. Working with the BinaryWriter object is especially simple because its Write method is overloaded to accept all the primitive. The BinaryReader class exposes many Readxxxx methods, one for each possible native data type, and a PeekChar method that returns -1 at the end of the stream.
Outputting strings with a BinaryWriter requires some additional care, however. Passing a string to the Write method outputs a length-prefixed string to the stream. The Write method is overloaded to take additional arguments that specify which portion of the array should be written.Need support for your remote team? Check out our new promo!

When you click the dynamically created label to "open" a folder, I need to get the value of the label so I can set a variable to it. I can't get the value because the label was dynamically create. Therefore the object doesn't exist.
Here's my code:. The event handler's sender parameter contains the label that generated the event. You can cast it back to Label by writing CType sender, Label. Learn more. Asked 7 years, 2 months ago.
