System.IO.File.ReadAllText("Filename.txt") 'but Then The File Is In Use When Try And Delete?
Mar 30, 2012
I am teaching myself VB.net and have pasted full code, and I want to delete the file called tracertAll.txt but I get an error "in use" message because I am doinga System.IO.File.ReadAllText("tracertALL.txt") but don't know how to release.Here is the code I think is the problem:
Dim MailBody As String
MailBody = System.IO.File.ReadAllText("tracertALL.txt") ' set it to path of the file which you want to read.

if we don't mention the decoding what decoding will they use?I do not think it's System.Text.Encoding.Default. Things work well if I EXPLICITLY put System.Text.Encoding.Default but things go wrong when I live that empty.So this doesn't work well
Dim b = System.IO.File.ReadAllText("test.txt")
System.IO.File.WriteAllText("test4.txt", b)

I don't know whether it is simple or not because i am new to programming. my requirement is : In my vb.net winform application, the filenames of the files present in "D:Project" willbe displayed in DataGridView1 control. Now I want to load these files one after another into memory stream buffer and add the headers("ID","Name","Class") to the content in the file. Then I want to save these files in "C:" with "_de" as suufix to the filename i.e.,sample_de.csv.

I'm using the FileSaveAs dialog control to allow the user to select a filename to save a file either as a doc file, an rtf file or a pdf file (that part was easy).However, after a bit of testing, it seems that the file extension doesn't automatically change when selecting the different file types.If the filename in the dialog is Foo.doc and I select FileType *.pdf and click "Save", my app still tries to save the file as a doc type.Virtually every other MS app automatically changes the extension to match a selected file type from the Office Suite to Paint. here's my code:
Dim dlg As New SaveFileDialog
dlg.InitialDirectory = m_sReportFolder
dlg.FileName = sProjectName & ".docx"[code]......

I am using System.IO.FIle.ReadAllText() to get the contents of some template files that I created for email content. Then I want to do a Replace on certain tokens within the files so I can add dynamic content to the template.Here is the code I have, it seems to me like it should work just fine...
Dim confirmUrl As String = Request.ApplicationPath & "?v=" & reg.AuthKey
Dim text As String = IO.File.ReadAllText( _
ConfigurationManager.AppSettings("sign_up_confirm_email_text").Replace("~", _
[code].....
For some reason I cannot get the %%LINK%% and %%NAME%% Replace() calls to work properly. I checked to see if it was encoding-related, so I made each file UTF-8. And also used the forced encoding overload of ReadAllText(String, Encoding) and still no dice.

I am working on a VB Console Application that takes an Autocad drawing type DWG and converts it to a PDF using a shell command that calls a third party application. In this case, acmecadconverter.exe from www.dwgtool.com. Then the PDF that is created needs a unique watermark, so I call a second application for that called pdftk.exe from www.accesspdf.com/pdftk/.
Everything works as intended, except when I try file names that contain spaces. The file system object does not tolerate spaces in the drawing file name. For instance, the following command gives me a system.io.filenotfoundexception...
My.Computer.FileSystem.RenameFile("Test Flowchart1.dwg", "Test~Flowchart1.dwg")
It's the same problem for all of my File System commands. Either file not found or invalid arguments.
The complete script I'm using is here:
Code:
Sub Main()
Dim arrArgs() As String = Command.Split(","), _
i As Integer, folderPath As String, myPart As String, _

I have a workbook (Workbook1) that runs through some steps using visual basic, which ends up opening another workbook Workbook2). Once Workbook 2 is opened, I need to copy a section of data from it, into Workbook1 int a specific worksheet. I was able to do this by recording a macro, but the challange is, the name of Workbook 1, and Workbook 2, will vary by User. When I created the macro it uses the files as they are currently named. The section of code is below.

I get the common error: " 'File Name' is currently being used by another process..."
My problem is that I have two forms. If the file doesn't exist in the one then it creates the file and opens up the other form, if the file exists it doesn't do anything, however, in the other form that it opens up I have it "attempting" to write text via StreamWriter. But my problem occurs when the StreamWriter tries to open the file for writing, that is when the program tells me that the file is currently being used by the other process.
In my first form I close the form via Form.Close and all I am using to create the file is System.IO.File.Create. Now I know that the System.IO.File.Create is causing the error because I have this process checking the very first thing on the program load. I am trying to find a work around the System.IO.File.Create but no luck here... I am trying to create a .txt ... lets say test.txt .

I have an application, that I have integrated into Windows Shell, for this example I will use Notepad. You can right-click a file on the desktop and select 'Edit with Notepad', this launches(if I am not mistaken 'NotePad %1') notepad, and opens the file right away for editing.For my application I need this to get the file name, so basically I would right click on my application, and it will run and have the filename for me to use inside the application.

I'm looking for a way to get the name of the file that's currently selected in a Windows Explorer window, desktop included, without having to use a FileDialog or to copy the path to the clipboard (GetFileDropList). I've been looking into the System.IO.Path.GetFileName() an many more methods like that, but I haven't found anything that does the trick.

I want to create VB.NET code that will change the filename of selected image files that are already stored on my ISP's web server. I know how to do this by reading the image into memory and then saving it as a new file. However, I would prefer not to regenerate the image. I just want to change the filename. Is this possible?
