I want to make a form, which downloads a textfile from the internet. I found this method on the Microsoft Website:
My.Computer.Network.DownloadFile _
(..Adress Here.., ..Output here..)
this works for me
[Code]...
Application.StartupPath & "Data(the name & extension of each file)" I can change the file.txt with other links. But the file have to be in the Data folder.d.
I need hep to make a buton, where you click it, then it downloads a file to a set folder, i have tried this forever, and i need a button to launch a program
View 3 RepliesI'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].
In links.txt are these links:
[URL] .....
If I run a program, it will download first link, after finish download it will download fifth link, second link etc. Downloading of one link works fine for me, but I need download more links...
Code:
theRequest = WebRequest.Create("[URL]")
So I need: theRequest = WebRequest.Create("RANDOM LINK")
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

Normally CSV files I work with lookes like this : d,e,f,g,1,2,3,4,5 What I am trying to do now is importing a CSV file that contains a title field, HTML description field ect. so at the end the CSV file format looks like this:"Record Title",1,2,3,"HTML description, which contains "",, ect",1,2,3,4,5, I need to know how to work with the above CSV format, where all the strings are inclosed with "" and may contain commas, so I can't use the split function as is to split where it incounters a comma as it may be part of the HTML description or Title field.

View 2 RepliesI am trying to read in and eventually manipulate an 'XML-type' file. I have picked up a hobby called 'Geocaching', some people probably have heard of it, where you use gps coords to locate items placed by other people. Well, you can download the gps coors within data files from the website,'Geocaching.com' and these files are in a XML format.
There are a lot of programs out there that people offer, some are better than others, but I am not happy with the results. So, I am trying to see how I can use these files myself and create my own program to use the data in a way that I want to use it.
I have tried to use Linq, XMLdocument, XMLreader and probably a couple of others over the past week. I have had marginal sucess with each of these methods, but nothing great and I owe that to my lack of knowledge.
I eventually hope to add the data to a Access db that I am using and manipulate the info from the db.
I am attaching a sample of one of the downloaded files and if someone would have the patience to help me work my way through it, p.s. The file typically ends with '.gpx', but since its an xml and thats what the system recognizes, I added the extension in order to upload the sample file.
I've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then
EnglishForm.Show()
ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.
I'm trying to read a text file that contains info like this:
ACX-101-011 , J2168
BTXR-130A-013, D6733
AJ4-233-614, T8211
I want to split each line at the comma and write the left side to a textbox and the the right side to another textbox. I'm close, with the code below, but I can only post results from the first line in the file. How do I loop this and append the text results in each of the textboxes.

My program reads a 3rd party .txt file using OleDb and reads the file into a datatable. It's overall working fine except a user will occasionally have a problem reading a file. At this point.
Line that gets hung up
Try
Dim comm1 As New OleDbCommand("SELECT * FROM " & safeFileName & " Where " & Status & " = '" & StatusClosed & "'", con)
Dim dasold As New OleDbDataAdapter(comm1)
dasold.Fill(dtsold)
AddColsold()
[Code] .....
It can not retrieve a date for one of the fields, then gives error and does not get dates for each records after the one it gets hung up on but the date is in the file. If I open the file in excel and play with the column sizing, for instance just autoformat column width then it read the date and will work fine. I have looked at the file in notepad and cant see anything wrong in particular on the record it gets hung up on. I have no control over the .txt file since it comes form a 3rd party.

I'm reading a file into a buffer using the Space function. Then I'm using blowfish dll's to encrypt it, and want to write the encrypted data to a txt file. (I realize you can use .NET cryptography classes, but I need to use these old blowfish dll's for this project.) Anyway, when when I encrypt the data in the buffer, I can see all encrypted data, but when I write it out to a file, I get a few lines of encrypted data and the rest of plain text.

So, when I Split the string with Comma, it gave me problem. Actually total it has 6 columns. But because of internal comma, it gave me 7 columns. And this CSV format can't change so I must deal with this problem. And so here I come out with a solution (because of its too long, I looking for better idea and solutions from you guys ):

I am trying to import a TAB (NOt comma) delimited text file into a DataGridView. The following code works fine if I have a comma separated file.

View 18 RepliesI'm a little new to VB, and I'm in a class for it, but I'm trying to do something we aren't going to learn in the class (mostly out of sheer interest) and I need help. I'm trying to read lines from a text file into a listbox, each line representing a new item on the listbox. For example, if the text file reads: [code]I want to be able to take that as is and read it into a listbox, where those words would appear in the exact same fashion; as a list, each as separate items. I've looked at the Help stuff and learned (sorta) about delimiters... but the thing is I don't want to write my entire list in a continuous line separated by commas--I want it to keep reading each line, and moving on to the next, until there are no more lines left. I am thoroughly stumped, and would appreciate it SO much if someone could help. For a frame of reference, this is the point I'm at now with my code: [code]Note that when I run the program, all it will do is read the first line of text available and stop; once I press ENTER in a text file, it decides to stop reading.
