C# - Read Entire File Content Asp.net?
Sep 1, 2010
get the whole and same content of any file i uploaded, for my editing purposes in my editor w/c retrieves file from the database. i.e of files are ".doc and .txt"and by the way what i meant by same content is the whole same appearance of my .doc or .txt file i.e "if the text is bold, forecolor is red and etc.."
i successfully established a file upload and a function to store it in a database... but what i'm missing is the whole and same content of the file. Another thing is i don't want the file to be saved in a local folder or somewhere..i just want it to be save directly to my database Below is my sample code of trying to retrieve the content.. but it is an error when you run..
Private Sub cmdSave_Click(ByVal sender As Object, ByVal e As System.EventArgs)
If filMyFile.PostedFile IsNot Nothing Then
Dim fs As FileStream

I already know the basic procedure of how to read specific cells of an .xls file using VB.NET but I can't figure out how to automatically get all the data from such a file.Basically, I'm obtaining the data like this:
Dim xlApp As Excel.Application
Dim wb As Workbook
Dim ws As Worksheet
xlApp = New Excel.Application
[code]....
In this case, I know that there will be content in the first 10 rows of the columns A, B and C but what would I have to do if I had a huge document whose size and content might even change from time to time? I know that there is also an attribute ws.rows.count but this always returns a big value like 60000 even if only a few rows are occupied.So basically, I'm looking for a simple way to loop through all the used rows of an Excel file with the possibility of accessing each cell in that row.

I'm trying to read and load the content from the attached text file to a arraylist with the code bellow.
but what is happening is that not all the lines from the text file are loaded in to the arraylist, the reading jumps from one line to other in the text file.
Dim FILE_NAME As String = ((My.Application.Info.DirectoryPath).Substring(0, (My.Application.Info.DirectoryPath).LastIndexOf(""))) & " est.txt"
Dim lista_barras As New ArrayList
Dim lista_barras_esp As New ArrayList

I have created several different colored 6 x 9 pixel rectangles (with a white border). I'm placing these rectangles on a large map, based on x y location and color code from a database. As I'm building the database, I occasionally run the program using the Debug in VB Express just to make sure everything is being place in the right location. I started getting an error when my rectangle count got up around 4500.
System.ArgumentException was unhandled
Message="Parameter is not valid."
Source="System.Drawing"
The release .exe works fine with no errors and a count of 6700 ... so far. As it is now it's taking near 60 seconds to place the 6700, and I'll eventually have 10,000 plus. (P4 3.20 GHz - 1 GB Ram). I'm placing each rectangle on the image as I read a row of data. Would it be beneficial to read the entire table into and array and then plot the rectangle?Would I be better off drawing each rectangle as needed or placing a my pre-drawn rectangle ?

The address I need to read is a java servlet that processes parameters passed in, generates a text document on the server, and then redirects to another URL and returns the address of the text file on the server. I then need to download that text file and process it. I'm having problems connecting to the first URL with the parameters and I think it has to do with the redirect.
I'm using the WebRequest object and I've tried using the HttpWebRequest object. Are there any other objects that support redirects?

nLog for .NET has the capability to send log entries as email. But if we want to send the entire current log file, how can it be done, short of reading the log file into a string and passing that as an nLog {$message}? I don't see that nLog has a property in its mailtarget for attachments.

Using the Microsoft VB 2008 Express program, I'm making a SWd20 character sheet (D&D) to be distributed to a few friends. It's a program where the user can figure out stats, species, class, etc without having to make any calculations him/herself.. but this will all be in vain without saving it..
So I'd love to know how I could make it so the user can save and load the entire file(including buttons, labels, text boxes, menu strips, possibly multiple forms, etc) on his/her own computer.. Is this possible, and if so, how can I go about this?
I've already searched through and found lots on saving text in the files to .txt files, but that doesn't cover everything I need

I'm having an issue with the streamreader. I had it working but I've changed something and it has stopped.
I have it in a Do While loop reading line by line, but it doesn't finish reading. It reads about 27 lines out of 4000, then stops.
I changed the contents of the file it was reading, but it's still just save as a txt notepad file.
I also changed how I tell it which file to open (UserSelection.T2) however it does open the file just doesn't finish reading it.
Doesn't kick back any errors, it just doesn't read the entire file.

Here is the thing, I have a rather bit datagridview on a form and, I would like to print that to a bitmap.
I've tried something like this:
VS2010
Public Sub SaveToImage()
Dim SFD As New SaveFileDialog
[Code]....
PS: I have modded a little bit this datagridview so it looks like a gantt chart with collapsible rows, and variable & multiple timelines at the same time, so the bars might go a long way to the right of the screen, that the main reason for the save to bitmap.
