It is possible to add open only files with *.bin extension in openfile dialog ?
Here is my code. Maybe somebody can fix it.
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim OFD As New OpenFileDialog
Dim fullFile() As Byte
If OFD.ShowDialog = Windows.Forms.DialogResult.OK Then
fullFile = File.ReadAllBytes(OFD.FileName)
TextBox1.AppendText(fullFile(&H1E).ToString("X2") & " ")
TextBox1.AppendText(fullFile(&H1F).ToString("X2"))
End If
If file have another extension msg,box : Wrong file
You need to use the Filter property: MSDN
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim OFD As New OpenFileDialog
OFD.Filter = "BIN Files (*.bin)|*.bin"
Dim fullFile() As Byte
If OFD.ShowDialog = Windows.Forms.DialogResult.OK Then
fullFile = File.ReadAllBytes(OFD.FileName)
TextBox1.AppendText(fullFile(&H1E).ToString("X2") & " ")
TextBox1.AppendText(fullFile(&H1F).ToString("X2"))
End If
End Sub
The pipe | character is used in the filter string to separate it into chunks: the first is what the user sees in the dropdown, and the second is the actual filter that is run on the files. You can have multiple filters available, too. Here's another example of a filter string: Text files (*.txt)|*.txt|All files (*.*)|*.*
You need to use javax.swing.JFileChooser.
Use this:
FileNameExtensionFilter filter = new FileNameExtensionFilter("Binary Files", "bin");
JFileChooser fileChooser = new JFileChooser();
fileChooser.setFileFilter(filter);

I'm trying to copy a file from an external drive by reading its contents, creating a new file elsewhere and writing the contents into it. My code shows no errors (using MSV) but when I try to 'download' the file, it completes the code but no file is created.
Can anyone help?
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
Dim FileReader As String
FileReader = My.Computer.FileSystem.ReadAllText(Label32.Text)
Dim fbd As FolderBrowserDialog = New FolderBrowserDialog
Dim DownloadLocation As String
If fbd.ShowDialog() <> DialogResult.Cancel Then
DownloadLocation = fbd.SelectedPath
File.Create(fbd.SelectedPath & "pandora speedsign log.txt").Dispose()
File.WriteAllText(fbd.SelectedPath & "pandora speedsign log.txt", FileReader)
MessageBox.Show("success!!")
End If
'File.Create("C:\Users\%UserProfile%\Downloads" & DownloadFileDate & ".txt")
'File.WriteAllText("C:\Users\%USERPROFILE%\Downloads" & DownloadFileDate & ".txt", FileReader)
End Sub
I've been looking for different ways of creating the file, different ways of writing the file but nothing seems to work.
We can significantly simplify the code like this:
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
Dim fbd As New FolderBrowserDialog()
If fbd.ShowDialog() <> DialogResult.Ok Then Exit Sub
Dim outputPath As String = IO.Path.Combine(fbd.SelectedPath, "pandora speedsign log.txt")
IO.File.Copy(Label32.Text, outputPath)
End Sub
i'm trying to use the savefiledialog tool, but it don't create the file to the selected destination...
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
Dim saveFileDialog1 As New SaveFileDialog()
saveFileDialog1.Filter = "txt files (*.txt)|*.txt"
saveFileDialog1.Title = "Save a Text File"
If saveFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK & saveFileDialog1.FileName.Length > 0 Then
RichTextBox2.SaveFile(saveFileDialog1.FileName, RichTextBoxStreamType.PlainText)
End If
End Sub
The binary logical operator AND in VB.NET is expressed with the keyword AND not using & (string concatenating operator)
If saveFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK And
saveFileDialog1.FileName.Length > 0 Then
....
If you set Option Strict On this problem will be signaled at compile time
(By the way, there is no need to test for the filename length. The dialog doesn't close if you don't supply a filename)
I have already viewed the MSDN Example but I am still having problems.
I created a super-simple program to multiply two numbers, and display the output in the textbox. Now I need to be able to read that text box value and put the value in a text file, bringing up the save to file dialog when the "Save To File" button is clicked.
Private Sub MutiplyBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MutiplyBtn.Click
Dim FirstNum As Double = Num1.Text
Dim SecondNum As Double = Num2.Text
Dim Answer2 As Double = FirstNum * SecondNum
Answerbox.Text = Answer2
End Sub
Private Sub SaveResultToFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveResultToFile.Click
Dim myStream As Stream
Dim saveFileDialog1 As New SaveFileDialog()
saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*"
saveFileDialog1.FilterIndex = 2
saveFileDialog1.RestoreDirectory = True
If saveFileDialog1.ShowDialog() = DialogResult.OK Then
myStream = saveFileDialog1.OpenFile()
If (myStream IsNot Nothing) Then
System.IO.File.WriteAllText(Answerbox.Text)
myStream.Close()
End If
End If
End Sub
Currently, Visual Studio is giving me an error: Overload resolution failed because no accessible 'WriteAllText' accepts this number of arguments.
WriteAllText static method requires the name of the file where the data should be written to.
You could use directly the name selected in the saveFileDialog1
If saveFileDialog1.ShowDialog() = DialogResult.OK Then
System.IO.File.WriteAllText(saveFiledialog1.FileName, Answerbox.Text)
End If
instead if you really want to use the stream opened by OpenFile() method your code should be
If saveFileDialog1.ShowDialog() = DialogResult.OK Then
Dim sw As StreamWriter = new StreamWriter(saveFileDialog1.OpenFile())
If (sw IsNot Nothing) Then
sw.WriteLine(Answerbox.Text)
sw.Close()
End If
End If
The code is an example, you need to add a bit of error handling
Hi I tried above method but I succeed in this way....
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
SaveFileDialog1.Filter = "TXT Files (*.txt*)|*.txt"
If SaveFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK _
Then
My.Computer.FileSystem.WriteAllText _
(SaveFileDialog1.FileName, RichTextBox1.Text, True)
End If
End Sub
In the first start of my application I need to specify a path to save some files to it. But in the open file dialogue it seems like that I have to select a file to open. How can I just specify a folder without oppening a file
like C:\config\
Here is my code
If apppath = "" Then
Dim fd As OpenFileDialog = New OpenFileDialog()
fd.Title = "Select Application Configeration Files Path"
fd.InitialDirectory = "C:\"
fd.Filter = "All files (*.*)|*.*|All files (*.*)|*.*"
fd.FilterIndex = 2
fd.RestoreDirectory = True
If fd.ShowDialog() = DialogResult.OK Then
apppath = fd.FileName
End If
My.Computer.FileSystem.WriteAllText(apppath & "apppath.txt", apppath, False)
End If
I need to select a file in order for it to work, but I just want to select a folder. So what's the solution?
You want to use the FolderBrowserDialog class instead of the OpenFileDialog class. You can find more information about it here:
http://msdn.microsoft.com/en-us/library/system.windows.forms.folderbrowserdialog(v=vs.110).aspx
For instance, you could do this:
If apppath = "" Then
Dim dialog As New FolderBrowserDialog()
dialog.RootFolder = Environment.SpecialFolder.Desktop
dialog.SelectedPath = "C:\"
dialog.Description = "Select Application Configeration Files Path"
If dialog.ShowDialog() = Windows.Forms.DialogResult.OK Then
apppath = dialog.SelectedPath
End If
My.Computer.FileSystem.WriteAllText(apppath & "apppath.txt", apppath, False)
End If
If I understand correctly, you want to let the user choose a folder. If that is the case, then you want to use FolderBrowserDialog instead of OpenFileDialog.
Dim filedialog As New OpenFileDialog
filedialog.IntialDirectory = Application.StartupPath
filedialog.ShowDialog()
Or you can simply just make it less lines and very simple.

Start your dialog with a click:
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
FolderBrowserDialog1.ShowDialog()
End Sub
Add if you want to show the actual path that you choose from your dialog
Private Sub FolderBrowserDialog1_Disposed(sender As Object, e As EventArgs) Handles Button1.Click
TextBox1.Text = FolderBrowserDialog1.SelectedPath.ToString
End Sub
Use To:
Dim openFD As New OpenFileDialog()
Dim Directory As string = openFD.FileName
Try this
Private Sub BtnOpen_Click(sender As Object, e As EventArgs) Handles BtnOpen.Click
Dim openFileDialog1 As New OpenFileDialog()
openFileDialog1.InitialDirectory = "x_pathfileforsend"
openFileDialog1.Filter = "txt files (*.txt)|*.txt|*.zip|*.rar|*.ico|*.exe|*.png|*.bmp|All files (*.*)|*.*"
openFileDialog1.FilterIndex = 5
openFileDialog1.RestoreDirectory = True
If openFileDialog1.ShowDialog() = DialogResult.OK Then
txtpath.Text = openFileDialog1.FileName
End If
openFileDialog1.Dispose()
End Sub
Hello i store proxys in a notpad.txt file and im trying to grab all proxys in the notpad and put them into listbox1
i am using
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Using Ofd As New OpenFileDialog
Ofd.Filter = "All files (*.*)|*.*"
If Ofd.ShowDialog = 1 Then ListBox1.Items.AddRange(IO.File.ReadAllLines(Ofd.FileName))
End Using
End Sub
I click it the button it lets me pick a file but does not import the stuff in the file to listbox1
Please help
I tested your code and it works for me, so I assume the problem is with the format of your file. How was the file created? Could you provide a link to it so I can take a look?
One thing to note, you should use the DialogResult Enumeration instead of the magic number 1 for the OK result to improve the readability and maintenance of your code.
If Ofd.ShowDialog = DialogResult.OK Then ListBox1.Items.AddRange(IO.File.ReadAllLines(Ofd.FileName))
try this example add it if you click on the OK button
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Using Ofd As New OpenFileDialog
Ofd.Filter = "All files (*.*)|*.*"
If Ofd.ShowDialog = 1 Then
'Pass the file path and file name to the StreamReader constructor
Dim sr As New StreamReader(Ofd.FileName)
Dim line As String = String.Empty
Try
'Read the first line of text
line = sr.ReadLine()
'Continue to read until you reach end of file
While line IsNot Nothing
Me.listBox1.Items.Add(line)
'Read the next line
line = sr.ReadLine()
End While
'close the file
sr.Close()
Catch e As Exception
MessageBox.Show(e.Message.ToString())
Finally
'close the file
sr.Close()
End Try
End If
End Using
End Sub
