Downloading A Text File In ASP.NET Is Appending The Webpage HTML?
Mar 3, 2009
For some odd reason, when I download text files, the HTML of the web page is being appended to the text! All other file types work fine!Here's the code that's doing the download:
Public Sub DownloadBlob(ByVal Blob As Byte(), ByVal FileName As String, ByVal Response As HttpResponse)
Response.AddHeader("content-disposition", String.Format("attachment;filename={0}", FileName.Replace(" ", "_")))
Response.ContentType = String.Format("application/{0}", Path.GetExtension(FileName).Substring(1))
Response.BinaryWrite(Blob)
End Sub

How do you access a web page's source code without downloading the file? i.e., downloading a .php file generally wouldn't work - I want to access the code that it would return if I was using a browser.

I am writing a program in VB.NET in Visual Studio 2010 to edit web pages that allows the user to download, edit and then upload HTML files.
To download I use:
My.Computer.Network.DownloadFile(New Uri(strSiteFileName), strLocalWebSiteFolder & strFileName, "", "", False, 100000, True)
My problem is that if the file being downloaded is an HTML file that includes a <!-- #include file = [filename] --> line then rather than just downloading, the file that is downloaded and saved actually includes the 'include' file's text, not the line to include the file. I just want to download the file including the reference line.
For example
if a file named 'footer.html' is simply one line as follows:
<p>This is the footer</p>
and a second file named 'index.html' is as follows:
<html>
<body>
<p>This is the main part of the file</p>
[Code].....
Is this a feature or am I missing something? All I want is the basic 'index.html' file to be downloaded.

Lets assume I have a DataSet that contains the following info (columns seperated with | character):
1 | Logan | Young
2 | John | Doe
3 | Jane | Doe
4 | Joe | Soap
If I now write this info to a text file, but later want to append 5 | Susan | Sarandonto the end of the text file, I obviously want to check that the text file doesn't already contain the data that I want to append to it. I'm having a little difficulty figuring out how to perform this check...I know you'd have to loop through every row in the DataSet's table and compare it to every line in the text file. That part's easy.

CommonDialog1.FileName = frmSplash.fp & "\job_info\" & nam
Open (CommonDialog1.FileName) For Append As #1

I have a VB 2008 program which shows the user's results in a ListView, and permanently stores them in a Notepad (.txt) file. The program works fine when I run it using Debug. The permanent records show up on a .txt file in the "bin". However, I want to publish the program as an executable file. I have tried this using my normal method of selecting "Publish" from the "Build" menu, and my program runs fine but there is no .txt file to be found.

Stuff like this makes me hate computers! Anyways, I'm again struggling with something relatively simple - or so i thought.I have a sub:
[Code]...
Then, I have a sub that runs every minute, calling yet another sub, which calls this one. Before you say whoa! that's too many, I'll say that each of these subs has a different purpose.The whole problem is that the WriteToFile sub writes only once to a file! Instead of continously writing to the file every minute, it stops at the first line.

I have a piece of software that can be used either on an admin account or a standard user account of a completely stand-alone, Windows XP machine.
I have also set up some log files that the system uses when it either performs an admin function or if an error occurs. the location of these files is a C: location - not (from what I can see) associated with the admin account in any way.
When running the software from the admin machine, the log file is appending fine. When running the software from the standard user machine, the log file causes an error, suggesting that "Access to the path 'C:HNP MTWP Log FilesAdministrative ToolsAdmin.log' is denied.
This error occurs when first setting up the FileStream. Here is my code.
Imports System.IO
Public Class Log
Private Const cnDirectory as String = "C:HNP MTWP Log FilesAdministrative Tools"

With the intention of creating a program to interface with a serial port device, I recently started learning vb.net. To keep the structure neat the vb code has been split into two places; the first is the code behind for initialising, clicking buttons etc., whilst the second is for managing the comm port. Respectively, these are named 'MainWindow.xaml.vb' and 'ComPortManager.vb'.
In 'comPortManager.vb':
Dim RXArray(2047) As Char ' Array to hold received characters
Dim RXCnt As Integer ' Received character count

I'm using this piece of code for VB.NET to download the text from a website:
Dim Str As System.IO.Stream
Dim srRead As System.IO.StreamReader
Dim req As System.Net.WebRequest = System.Net.WebRequest.Create("http://www.example.com/file.txt")
[code]....
It is just a text file, and is rather small, so it downloads really quickly. But I do believe that in the future the file will become considerably large. Is there a way to track the downloading progress from the above method?

What I am wanting to do is create a program that will load up a page (it is password protected) and get the links out of any files that I need to download. The green text is the text that contains the link and will be repeated for every file.One little thing is that there are multiple pages that are accessed through JavaScript with the code highlighted in red. So, I also need to step through the pages and get a list of all files on subsequent pages.
Everytime I run this program, it will get a list of all files and only download the ones that aren't already downloaded. However, I have never done this before and was wondering what I need.I have accessed the source of pages and parsed it for things like links before, but not sure if that is the optimal way or if there is some other way to handle this particular situation easier, especially since I have multiple pages to deal with and JavaScript.

I'm working a program, which will download files from my server. But I need, program will download random files from text file on server, for example: I have [URL].

Code:
theRequest = WebRequest.Create("[URL]")
So I need: theRequest = WebRequest.Create("RANDOM LINK")

How would I go about appending text to a Textbox without losing the current scrollbar position? I thought somehting as simple as:
Textbox1.Text += "MyString" & vbCrLf
would work, but it just sends the scrollbars to the top.

This append feature does not seem to work. I've looked in many places to no avail. The other examples below for writing and reading seem to be going fine.

Dim objWriter As System.IO.StreamWriter = file.appendtext("textTBD")
objWriter.WriteLine("textTBD")

The following code is giving me a headache. As you can see there are message boxes in there for a quick debugging tool. It displays the messagebox "Still looping" once, and then shows the form. No other code runs. Doesnt matter what I put it it just doesnt run. I can't see a problem anywhere....

The user starts out by pasting text into a textbox:
1.Phototypesetting was superior to automated typesetting because it was
(A)Easier
(B)Faster
(C)More flexible
*(D)All of the above
What I want to do is to tag the sentence and format it as follows: MC Phototypesetting was superior to automated typesetting because it was (A)Easier incorrect (B)Faster incorrect (C)More flexible incorrect (D)All of the above correct Using the following code I can easily replace the number (1) with MC:
TextBox1.Text = Replace(TextBox1.Text, ("1."), "MC ")
But for the life of me I cannot figure out how to tag each choice with correct or incorrect. The correct tag will go to the end of the choice which starts with * eg *(D) All of the above correct, while incorrect should go at the end of all other choices.

I'm trying to find a way to change the color of one word when appending text to a Rich text box. So if I append the sentence "This is a sentence with a specific word in one color" The entire thing will be in black except for the word "specific" it will be in red or any color I choose. The same thing will happen if the next line appended is "Please be specific in your request". All back except for the word "specific". I don't want the text added then someone has to click a button to change the color. It should happen as it's appended.

I would like to know how it's possible to append text between data.
For example:
I have a RTB with "ABC" on the first line and "DEF" on the third line. My question is how would I insert text data into the second line, without changing any existing data.

Usage: Users create pretty HTML news letters in another app. They post the newsletter to the web, but they also want to set the contents of the HTML news letter file as the body of an email and send it using Application In Question. The users understand to use absolute link and image references when sending an E Newsletter. Environment:
AIQ is a VB.Net app deployed via ClickOnce. It is an intranet app; one can be sure MS Office 2003 and the interop 11 dlls are on the target machines.
Restrictions: MAPI is out. It mangles the HTML. Since it is a ClickOnce deployment, we can't register dlls (I think, correct me if I am wrong). Therefore CDO and COM is out (again, I may be wrong.... I would be happy to be proven so).

I am trying to save the contents of a richtextbox to a text file. I know that they .SaveFile method automatically overwrites the existing file so I have a routine that will load the contents of the file into a temporary rich textbox control then append the new information to that and then save from the temp richtextbox. My application works as I want it to on my workstation but I cannot get it to work correctly on the notebook computer it will be running on from now on. It only works when I put in a breakpoint and I am not sure why?
[Code]...
If I put breakpoints on any of the lines rtb.Select, rtb.Copy, rtb.Paste then it works. I even tried putting a Thread.sleep before saving, thinking that more was needed to do the copy/paste but that didnt work either.
