I am trying to save a image from webbrowser but can't find an answer for it.
Example of the problem is the URL is hxxp://domain[.]com/image/?img=1234 on webbrowser it shows the image and the source is <img src='hxxp://domain[.]com/image/?img=1234'>..
I was unable to save it using the My.Computer.Network.DownloadFile and MemoryStream(tClient.DownloadData methods.
In order to download the file, I will need to session cookie also?
How can I do this?
Any image that you see in the WebBrowser has already been downloaded to your computer. It is normally cached in the folder:
C:\Users\<username>\AppData\Local\Microsoft\Windows\Temporary Internet Files
or whatever other folder is set in Internet Options. You can get your image from that folder.
The following program shows how to copy file TDAssurance_Col.png from the Temporary Internet Files folder to the C:\Temp folder.
Module Module1
Sub Main()
CopyFileFromTemporaryInternetFolder("TDAssurance_Col.png", "C:\Temp")
End Sub
Public Sub CopyFileFromTemporaryInternetFolder(filename As String, destinationFolder As String)
' Search actual path of filename.
Dim temporaryInternetFilesFolder As String = IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.InternetCache), "Content.IE5")
Dim pattern As String = Path.GetFileNameWithoutExtension(filename) & "*" & Path.GetExtension(filename)
Dim pathnames() As String = Directory.GetFiles(temporaryInternetFilesFolder, pattern, SearchOption.AllDirectories)
' If file found, copy it.
If pathnames.Count > 0 Then
File.Copy(pathnames(0), Path.Combine(destinationFolder, filename))
End If
End Sub
End Module

I am trying do display a pdf file on a form which contains a Web browser. I have previously used the below code which sometimes works but now I am constantly getting an error at line webBrowser2.Navigate pdfFilePath. The pdf file exists in the path and is named correctly. Please see the rest of code and help if you can:
Sub loadPDFFile()
Dim webBrowser2 As WebBrowser
Dim pdfPath As String
Set webBrowser2 = webControl.Object
pdfPath = Application.CurrentProject.Path & "\Internal Framework Summary.pdf"
webBrowser2.Navigate pdfPath
End Sub
Private Sub Form_Open(Cancel As Integer)
Me.webControl.ControlSource = Application.CurrentProject.Path & "\Internal Framework Summary.pdf"
End Sub
Private Sub Form_Load()
loadPDFFile
End Sub
Current Registry setting:
You may need a Registry setting:
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION
Try setting it to 0 (zero) to make the control to use the current browser emulation.

Bonus tip:
After setting MSACCESS.EXE to your preferred value, do
check the setting for OUTLOOK.EXE. Adjusting that will probably make
most of your received e-mail newsletters render as intended.
To display the file, use this ControlSource:
="=" & [URL]
where URL is the field holding the full path to the file wrapped in octothorpes, for example:

Hi I searched the web and found the example Open a folder using Process.Start to open the folder. I followed it and created a console app but the folder is opened my document folder instead of my input folder. For my testing, I executed it in cmd prompt by typing "\sharefuser01\users$\tester\2012". It opened the "\sharefuser01\users$" folder. Would someone tell me how to do it. Thanks in advance.
There is my code:
Sub Main(ByVal args() As String)
Dim psi As New ProcessStartInfo(args(0))
Process.Start("explorer.exe", args(0))
End Sub
Process.Start("directory path")
or
Dim Proc As String = "Explorer.exe"
Dim Args As String =
ControlChars.Quote &
IO.Path.Combine("C:\", "Folder with spaces in the name") &
ControlChars.Quote
Process.Start(Proc, Args)
I am trying to get the path of a file from the name of it. I made an executable file on my desktop, Commands.exe, I am trying to get the full path of it through a console application. I want the program to search the whole of my computer for the file, (it is on my desktop for simplicity) and return the path, bearing in mind the file could be anywhere. The path I want the program to return is:
"C:\Users\Jimbob\Desktop\Commands.exe"
My Code:
Imports System.IO
Module Module1
Dim fileLocation As String
Dim filename As String = "Commands.exe"
Sub Main()
fileLocation = Path.GetFullPath(filename)
Console.WriteLine(fileLocation)
Console.ReadLine()
End Sub
End Module
but instead it prints out
"C:\Users\Jimbob\Documents\Visual Studio 2012\Projects\get path
test\get path test\bin\Debug\Commands.exe"
It prints out the path of the project all of my code is in. In this path, there isn't even a Commands.exe in the Debug folder.
Help?
or couldn't you just
dim fileName as string = My.Application.Info.DirectoryPath() & "\Commands.exe"
You can use the Directory.GetFiles or the FileSystem.GetFiles methods to do this.
Something along the lines of:
fileLocation = My.Computer.FileSystem.GetFiles("C:\",
FileIO.SearchOption.SearchAllSubDirectories,
filename)(0)
I make a search program for searching a list of files in a computer and then copy the file into a store folder. The file name could be "*11*2.txt" As long as the program find this pattern, it should copy to the store folder. The problem is that I don't know the exactly name of the file before the search and I don't want to rename the file, I don't know how to save the file. Please help
I use the following to find the file, which does its work
Public Sub DirSearch(ByVal sDir As String, ByVal FileName As String)
Dim To_Path As String
To_Path = Form1.TextBox5.Text
For Each foundFile As String In My.Computer.FileSystem.GetFiles(sDir, FileIO.SearchOption.SearchAllSubDirectories, FileName)
Copy2Local(foundFile, To_Path)
Next
End Sub
Here is the current version of the Copy2Local (Note: it is not working right)
Public Sub Copy2Local(ByVal Copy_From_Path As String, ByVal Copy_To_Path As String)
' Specify the directories you want to manipulate.
Try
Dim fs As FileStream = File.Create(Copy_From_Path)
fs.Close()
' Copy the file.
File.Copy(Copy_From_Path, Copy_To_Path)
Catch
End Try
End Sub
First, you should check if ToPath is a valid directory since it's coming from a TextBox:
Dim isValidDir = Directory.Exists(ToPath)
Second, you can use Path.Combine to create a path from separate (sub)directories or file-names:
Dim copyToDir = Path.GetDirectoryName(Copy_To_Path)
Dim file = Path.GetFileName(Copy_From_Path)
Dim newPath = Path.Combine(copyToDir, file)

(disclaimer: typed from a mobile)
To answer your question: You can get the file name with Path.GetFileName. Example:
Dim fileName As String = Path.GetFileName(foundFile)
However, there's a bunch of other things wrong with your code:
Here,
Dim fs As FileStream = File.Create(Copy_From_Path)
fs.Close()
you are overwriting your source file. This does not seem like a good idea. ;-)
And here,
Try
...
Catch
' Do Nothing
End Try
You are throwing away exceptions that would help you find and diagnose problems. Don't do that. It makes debugging a nightmare.
In vb.net, I'm using the following code to find the filename
Textbox1.Text = New FileInfo(OpenFileDialog.FileName).Name
this code work fine with open file dialog box
How do I get a file's directory when open with or send to event happens?
I want it like media player, the application can get the file name & path when the user runs it with Open With.
The filename will be pased on the command line to your application, so you can access it by either
Module MainModule
Sub Main(cmdArgs As String())
Dim fileName as string = cmdArgs(0)
End Sub
End Module
For a console application, or by
Dim args As String() = Environment.GetCommandLineArgs()
Dim fileName As String = args(1)
For a GUI application.
Note that when using Environment.GetCommandLineArgs(), the first element in the array will be the full path to your executable, so you need to access the second element to get the file name. In the first example, cmdArgs will only contain the file name parameter.
To get the directory name containing the file, you can use
Dim path as String = System.IO.Path.GetDirectoryName(fileName)
