View 2 Repliesim trying to read a online txt file and its not working [code]but it has a uri error i think in doing it wrong but need help with how im doing it wrong, all i want to do is read the text from a file online not from the system should be easy.
View 1 RepliesUsually, the text file that would need to be read and processed would be local (on the computer the program is run), but for this example, we need to get the data from an online text file.
I have searched on google for nearly an hour now and haven't found anything of any real use. One of the earlier projects we submitted used a similar target, and I managed to get it working fine, however I dont have the original source code with me and I cannot remember how I did it.
I believe I used a Net.WebRequest method of some sort, because I had tried using StreamReader and ended up with an URI error or something like that.
Downloading the string would use too much, is there a way i can read it straight from the WebPage without having to download it? It's a a two row table.
I need to compare a TextBox entry to something in the List -first row- and then pull some data from the second row.
im trying to read a database that is online. My goal is to be able to store a database online, and be able to edit it through my application and the web (the web part is done). all that remains is the application.

View 3 RepliesI'm new to Visual Basic. I'm trying to get this code to read a .txt file line by line. If the only thing that the line says is "B" it should add one to the intTotalBoys integer and so on with G for Girls, F for Fathers, and M for Mothers. I'm not sure why it won't work. [code]
View 4 RepliesI have a grid view with a nested text box in it. I would like to turn view state off but the fact of the matter is when data is posted, the text boxes inside the gridview aren't available (there are no rows in the gridview on postback)I am using ASP.NET 2.0 so would this fall into control state, not view state?
Sample ASPX code of the gridview:
[Code]...
Control's information is not stored in the View State (for things like selected value and .text etc.)Control state, introduced in ASP.NET version 2.0, is similar to view state but functionally independent of view state. A page developer can disable view state for the page or for an individual control for performance. However, control state cannot be disabled. Control state is designed for storing a control's essential data (such as a pager control's page number) that must be available on postback to enable the control to function even when view state has been disabled.[URL]..
I need to read in each line of a file that is comma delimited and I know how to do this.ut for this file, some of the values have quotes around them that contain commas and others do not. For example, the name field has "Doe, John and Lisa" and the other fields do not. How will this be handled? Will it read that whole field in as one or will it still seperate it as seperate fields?

I have several quesions about reading/writing structures from/to files.In a scenario when I open a data file having its own header and variable data fields I create a structure that represents a header consisting of 9 bytes:
Public Structure HeaderInfo
Public DataField1 As Integer
Public DataField2 As Byte
Public DateField3 As Integer
End Structure
I'm using this code for the time being:
vb.net
Public Function ReadHeader(ByVal FileName As String) As HeaderInfo Dim ReturnInfo As HeaderInfo Try Using br As New IO.BinaryReader(New IO.FileStream(FileName, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)) With ReturnInfo
[code]....
The first question is - can I fill the structure directly somehow? Some structures are very long and filling them this way will be tedious. For example, if I know the length of the structure I could read the needed number of bytes in a byte array and somehow marshal these bytes into the structure.I can use Marshal.PtrToStructure, but then I would need to get an IntPtr of my byte array. I use <Serializable()> attribute for my structure.
Here's what I have that Doesn't work (I have one button, one OpenFileDialog, and a label named Status):
Public Sub ProcessBytes(ByVal Bytes() As Byte)
Status.Text = "Status: Processing . . ."
Try

I've got a program which reads a text file, in this file there are 2 or 3 lines between paragraphs. However when displaying in my textbox on my form i have 14-18 lines. Why? and how can I remove them?
View 3 RepliesOk so there is an XML file for a program that already exists that stores a list of files along with other information.I need to open this file and read the file names and then potentially add files to it if they DO NOT already exist in the file.It is very important that I not wipe the XML file and have to write it from scratch every time.
