I have the following code that I am using to parse out a test file. I am getting variable conversion error in Sub Main() when I assign file = Read(). The return value of Read() is a TextFieldParser type. How do I assign the proper variable type to "file" so I can write the output to a text file?

Is there a simple way to create a file for this type of data?
I want to read through a flat file, find the line starting with the number I want, and edit that line.So if the file looked like
01435804385043295
02843759248752092
03854379857394857
and I want to edit the value 4375 in line 02 (pos. 4-7) to be 4376.I know I can read it with a streamreader, and write to the end or entire file with streamwriter, but how can i read and write at the same time?
Downloading the entire file to a string and then recreating is NOT an option.
How do I make a file? Or someone choose a file they want to create but I know how to write to it.
View 2 RepliesI want to write a line into a text/.cfg file. The line is = name "ishtiak". I need a sapce between name & "ishtiak". The text "ishtiak" is loading from a textbox called textbox1. I dont want in the text box my name like this "ishtiak" it will be without "" like this ishtiak
but in the text file it will add "" before & after my name.
So the question is
1. How to add space between name & "ishtiak"? like this = name "ishtiak"
2. My textbox text will be ishtiak,but it will be written like this "ishtiak"

I have an application that currently stores PDF files (and others) inside the database as BLOBs. The trouble with this method is that I've now got SQL Server databases in excess of 200 GB! I've finally figured out a way to still enable full-text search without needing to store the PDF files as BLOBs (yay! Adobe's iFilter isn't great.), but I'm having trouble designing the method for a client to get access to the files stored on the server's file system.
I want to place the files in a restricted directory on the server, so I can't simply pass a UNC path to the client and let them open the file from there either in a browser or using Process.Start(filename). I understand how that would work, but if that directory has user access granted, all sorts of security holes open up, right?So, what I'm thinking about is a way to have a SQL Server account that has read/write access to/from the protected file system directory. That way (in my mind), the SQL Server can take a file as it's loaded in through the import client (as a series of byte chunks) and write the file to that area of the filesystem. Then, when a file is requested, the SQL Server can bulk load the file into a varbinary(max) field and do whatever I want with it.
1. How can SQL Server take a stream of bytes and write them to a specified location on its local file system? (This is assuming that I want the import utility to be able to be run on a client machine and not require it to be run on the server itself.)
2. Is there any way to stream a varbinary(max) file to a web page out of SQL? I'm using a lot of PDF files that will have Fast Web View enabled, so if I can stream the bytes to a web page, the user will be able to see the first few pages of the document while the rest is loading. I thought about having the SQL Server read (bulk load) the file from the protected area and write it to an unprotected area just long enough to point a web browser to that location, then wiping the file, but that brings me back to #1 above and would THEN require me to be able to issue a delete command from SQL.

View 8 RepliesI've searched everywhere to find out why the heck my program is doing this, but couldn't find anything like it...? I'm making a flash card program. Part of my program takes images corresponding to other data from a certain area, chosen by the user, and moves them to another folder, for later use. I want to store the path for the image next to the other data, storing the path as a string. When no image is chosen, the variable for the path is simply "no image".

View 5 RepliesCurrently, I've encountered a problem where I do not how I can store the variable of my battery level in a text file. I tried .xml and .txt file and it returns me text which can't be read.The code related:
vb.net
[code]Dim psBattery As PowerStatus = SystemInformation.PowerStatus
Dim perFull As Single = psBattery.BatteryLifePercent
[code]....
The place where I do not know what to insert is the "Insert Battery Percentage Here" part so I guess that's the problem.For your info, if you were to use a MsgBox to display, the code which displays that would be <MsgBox("Total battery power remaining: " & perFull * 100 & "%")>

I know how to declare a variable, a function, to write a string of characters or numbers (I still looking in tutorials and depict from there what i need to know) but...WHAT I DONT KNOW is how to USE them? At "what" or "how" are you thinking when you make a program? I try for SOME LOooNG TIME to understand but I think im too stupid to understand from pages on the net (or i dont find THAT tutorial who can explain right for me).I try a lot of programing languages starting with pascal,c,c++,darkbasic,alice, Visual-c,c#,c++,basic,php,even assembler, some programing zones in Excel and Word but from all of this i cant manage to understand the life behind the words.

I have a little problem regarding the use of DBNull, NULL etc. in VB.net in combination with SQL Server 2k.
More specifically, I want to do something along the lines of this:If x = 0 Then
x = DBNull.Value where x is declared by Dim x as Object. I would rather use Double, but I can't assign DBNull.Value to this, and using Object works quite well, too. But every time I hit this condition, I get an exception: A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll This is not a major show-stopper, since the database value I write x to in the next step, is NULL by default - most of the time! So I need the ability to write NULL to it. If that was not the case, I would have been able to work around this by catching exceptions, I think - but sadly, this isn't really of use then.
