I have searched the web for an answer to this but can not find one anywhere. I have a program that will be sending text to different text files based on a selection in some combo boxes, I was wondering if it is possible to select the file path based on the combo box variables eg
if the user selects hello and then 4 in the combo boxes then the text will be saved to
w = New IO.StreamWriter("c:projecthello4.txt")
or if they select hi and 5
w = New IO.StreamWriter("c:projecthi5.txt")
i have tried setting 2 variables called a and b and trying to run the following
w = New IO.StreamWriter("c:project{a}{b}.txt") but this does not work
I have 2 programs. Prog1.exe is in folder1 Prog2.exe is in folder1/subfolder
When I execute this in Prog1, Process.Start("subfolder/Prog2.exe") Prog2 runs.
But...When I execute this in Prog2, Dim sw as new streamwriter("1.txt") sw.write("something") sw.close
1.txt is created in folder1, and not subfolder. I can do a easy workaround by passing the full file path when creating the streamwriter, but I just want to know if it's a bug or what.
So, im using streamwriter and i want to create a folder and then save the text file in that folder.Here is the code im using right now.Imports System Imports System.IO Public Class Form1 Dim nr As Integer = 0 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Using sw As StreamWriter = New StreamWriter(DateAndTime.Now.ToShortDateString & ".txt")Add some text to the file.
In VB.Net, how do I provide the StreamWriter constructor with a path that includes spaces? StreamWriter("""C:UsersPublicPublic Usersfile.txt""") does not work.
I've seen a lot of threads in respect to file access denial, but haven't really found one that suited my particular issue. In my application the part that's not permitting the file to be saved is in the below code. I have 21 text boxes that I'm writing to a file that when in the developmental environment (Visual Studio 2010) works just fine however, when I create a setup program and then install it to a directory I get the infamous "Access to the path 'C:Program Files (x86)Blah, blah' umbers.dat is denied." before uninstalling it I took a look at the permissions on the file itself and ReadOnly is not the issue. I tried looking at the FileIOPermission Class, but find anything that would work for me or perhaps I was doing something wrong. [code]
I have a Access program and I'm using VBA code in the background to run Winunzip using shell command. Well, the path of the .zip file has spaces in it and it's not recongizing the path as a valid path. Is there a another way to tackle this problem besides the shell?I can't us pkzip either. Has you can see I had to use progra~1 instead of Program Files.[code]
I am taking in two html files and creating one out of them. To do this I am opening the first html file and not writing out the closing </body> and </html> tag and opening the second file and not writing out the corresponding opening tags, as well as the <style></style>section. I start a streamwriter, and write the lines out to it, and then close the streamwriter. My problem is that the output file is filled with strange characters. I've tried opening the streamwriter with different character sets as the third parm, but all this does is change the characters to different strange characters.It says charset=windows-1252 at the tops of the input files (and the output files for that matter - since I'm just reading stuff in and writing it out - with the exceptions mentioned above).Questions;First, do you think I am properly approaching appending two .htm files together?Second, how can I eliminate these strange characters.
I am having a big problem with deleteing a file form the server. I have the filename for a image stored in my SQL database. the problem is i am getting an error of "Illegal characters in path. " Here is the code below:Everything is working fine until the delete command.
Protected Sub DeleteButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Dim tmpEquipID As String = Request("EquipID") Dim tmpImageID As String = (CType(FormView1.FindControl("ImageIDLabel"), Label).Text) Dim d As New equippicsDataContext
Dim fs As New FileStream("C:est.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite)Dim b As New StreamWriter(fs)
b.WriteLine("hellothere") : b.Close()
b.close is necessary to save changes to the file, but then, fs will be closed, too. is there any method that does the same thing but doesn't close fs, like "b.save"???
VB 2005 now offers different methods to write/read a file, such as the File.WriteAllText, the My.Computer.FileSystem.WriteAllText and the StreamWriter.Can anybody explain when is it better to use which method, which one is more efficient in term of memory/processor use and performance time?
I am trying to read and display a file using MapPath as follows :
Response.ContentType = "Application/pdf" Dim FilePath As String = MapPath("../Document/123.pdf") Response.WriteFile(FilePath) Response.End()
This procedure will work fine and display in the browser. However, if I save the file to C:Document123.pdf, how can I access this file using relative path in MapPath function. Is there an option to access the file which is saved out of IIS server? I am using vb.net 2003.
encountering a problem when trying to write data to a text file. If I put the output into a messagebox I can see it, but when I attempt to write it to a file it is just blank. What am I missing here? EDIT - This is just a simple winform that I specify a path to a local HTML file in Textbox1 and I'm attempting to parse some HREF tag data.

I need to add a row of data to an exisitng TextFile that is in Tba delimited format. My program currently used ADO to read and update the table but that was creating to many problems with varying 3rd party providers of the Text File.
I am using the following code to write and empty (dummy) file to take up the remaining space on a device.RemSpace is a Public Variable declared as Long I have a function that gets the remaining space on the device and stores in the RemSpace variable (in bytes). I have tested with a msgbox to display the result of RemSpace, and it comes back correct (not 0). However, when the following code attempts to create the dummy file, the file is properly created but is only 0 bytes. What am I missing here?
I have a code which reads a text file through streamreader,selects what is important and writes the same to another fileusing streamwriter. The problem is that the streamwriter stops writing beyond a certain line and just doesnt write ahead.What can be the problem? Do I have to make two seperate files?

building another command-line app and I need to generate a log file and write to it throughout the app's run, but the log needs to be named <work_order>_<device>.log - both of those are held in a text file and will change frequently.
I can extract them no problem, and use them in the log file, but can't get the log file to use them in the name.
so I have:
Using strDATA As New StreamReader(DATA_FILE) Do While Not strDATA.EndOfStream Dim eng As String() = Split(strDATA.ReadLine, "=")
[Code]....
PATH and WORK_ORDER are declared as Public earlier on as are PATH, LOG, TMP and CSV, this sub is also Public. I also need to use the log writer in other subs as well as WORK_ORDER and DEVICE.
I am trying to read the content from a .csv file and storing it in a variable. Later I am writing that content into a newfile. Code is executing successfully but the data is not appearing in new file. Here is my code:
When the button is pressed the line is written to the file just fine, but if I restart my application, which calls Refresh_OtherLog() onLoad, it displays the lines of the text file as one line with the traditional square character depicting a character return. Why is it not putting that new lone as a new line in the listbox?
I am writing each line to a text file: Dim objWriter As New System.IO.StreamWriter(filename) For Each x In tofile objWriter.WriteLine(x) Next objWriter.Close() Which works perfectly the only problem is is that when its finished it writes a blank line on the end of the text file which I don't want.
I have an issue with StreamWriter class. Basically, in an application running as a web service, I need to write info into a log file. When I send 2 web service calls simultaneously, the entries created in the log file are not correctly written. For example, in call #1, ID 1 - xyz is to be written to the log file. In call #2, ID 2 - abc is to be written. When I viewed the log, it shows ID 1 - xyz & ID 1- abc. Looks like there's some memory data being shared and mixed together, even though it's totally 2 separate web service calls. From my understanding, each call (i.e. each will be process under a different application instance) should have its own set of memory allocation for data processing... If I am to make this application as a Console Application, it looks like everything is processed correctly.
i have a windows form created using vb.net 2005 that allows users to attach files. When the user clicks the AttachFile button, they browse to select a file they want to attach and then the code places the file they selected into a predetermined location. The primary file type they will be attaching is a windows meta file (.wmf).
The attached file is saved and appears as a hyperlink for the user to open at a later time. When the user clicks to open the file, it is suppose to insert it into Autocad; however, it wasn't doing this.
The problem comes from attaching the file using the StreamWriter for some reason its not working correctly. I verified that this is the issue: When i hardcoded the file path to the original file's location, it opens up just fine when clicking the hyperlink. When I compare file size from the original to the one attached, I see that the original is 12Kb and the one I attached is 19Kb.
Here's my code to attach the file: I'm thinking perhaps it has something to do with this line? sReadFile = sr.ReadToEnd() but I'm just not sure. I tried changing this line to sr.Read but that doesn't work either.
