IO.StreamReader & Replace Using Up Resources
Jul 1, 2011
I'm new Visual Basic. I played around with vba in Excel for about a year, but most of it was copy-clipping code that I found online and modifying it � which taught me the VERY basics. I was recently asked if I�d like to job shadow one of our programing consultants at my work and jumped at the opportunity. So my "mentor,� Temi, has been awesome in giving me some basics, and I've learnt more from spending a couple hours a day 2 days a week for the last month with him then I have since I got into this a year ago in vba.

I have a problem with a streamreader in visual basic 2008.I am updating a database from text files on an ftp server. The streamreader works fine until the file is more than 100,000 bytes long.It reads until it reaches this point and then just ends. No error message, it just reads to this point which happens to be 2 fields out of 6 in the database stream. My question is - does the streamreader have a limit? And if so what is a workaround?

conn = New SqlCeConnection(connString)
Dim strQuery As String = ""[code]......

I'm writing a program that basically loads an entire text file into a streamreader variable, then reads this variable line by line and parses and writes a line into a new text file. I'm VERY new and my knowledge is mostly self-taught, but I can't seem to get out of this one. It works for smaller files, but it appears to reach a limit in characters at some point because in a file of 900 lines, it stops writing about halfway through 800 and there are no errors, the program actually completes and the message box pops up.
There are a few things with this code I already know I should fix, such as creating the new text file name, it's messy, I just don't know how.
Private Sub btnProcess_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnProcess.Click
Dim IndexValues As String()

The file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below. I added the two rows with .replace code in green in expecting that to be enough but it is still not working.
Public
Sub Main()
Dim R1, O1, P1, C1, strDateFrom, strDateTo, strRunDate

String

I'm working on a timekeeping application in Visual Basic 2008 and am having trouble formatting a timespan for display. Here's how I want to the information:If a positive number my Label will be: lblTimespan.txt will show as "12 Hours And 15 Minutes" This works fine.If its a negative number I want to display it as "(12 Hours And 15 Minutes)'[ in red. The problem is that I can't get rid of the minus sign. [code] Thr Replace doesn't seem to want to replace the "-", can anyone suggest what to do?

I have a bunch of object variables which are all initialised in their declarations such that:
Private _myObject As New ThisObject("SomeString")
where ThisObject is one of a number of object types, but all are initialised using a string.
I would like to use the Visual Studio Find/Replace dialog box to search for "As New" then replace everything from "As New" to the first set of speech marks with some text such that:
EDIT
My original example could be solved using other methods. This example is more representative of the actual problem:
Private _myObjectA As New ThisObjectA("SomeString")
Private _myObjectLongName As New ThisObjectLongName("SomeString")

I am trying to think of a regex replace to replace double quotes with nothing. Example:
hello("hi there") would become hello(hi there)
"hi" would become hi
"example "3" would become example "3
-edit Maybe an easier way to explain this is, replace all " that do not have a backslash before them.

I am trying to filter out all unwanted characters from a string. All I want in the string is letters A-Z, numbers 0-9 as well as comma (,) plus (+) and quotes (").I figured how to do the letters and numbers, but the 3 special characters are giving me a problem. I also tried with the Chr(34) equivelant for the " sign, but no luck, as and " or , messes up the way the code is read. Here�s what I have so far, but it only works for A-Z and 0-9:
STR = System.Text.RegularExpressions.Regex.Replace(STR, "[^A-Z, 0-9, Chr(43) ]", "")

I am doing an assignment for my programming class in which we have a text document full of names (one per line), and we set up a program with a textbox, button, and listbox. The user enters a name in the text box, clicks the button, and it searches the document for the name. If it's found, the listbox should say so and list the line number.I can get that working no problem, but the assignment also requires informing the user if the name can not be found, and I am not doing something right with that.My code is as follows:
Quote:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim inputname As String = TextBox1.Text
Dim linecount As Double = 0
If I remove the three bolded lines and it finds a name, it will work fine to the point that it informs as such and tells what line it is on, but it won't inform the user if a name wasn't found, which I need. I thought adding those three bolded lines would help, but when I have them in there, it will incorrectly display "Name not found. " no matter what name I type in the box, even if it is in the text document.

I am testing code that recursively searches for files, reads them and determines if a user supplied text string can be found. I am getting Out of memory errors on files > 250 MB. The system has 4GB RAM and no other apps are running. Here is the section that throws the error. Other than this, the program seems to work perfectly. 250 MB files are OK, 275MB files are not.

magine there is search box (textbox), and below there are a search button with a rich text box.My text file located in the drive C is like this: [code]I want to search only two types of items in my text file located in drive C, namely: Construction and Non-construction. When the user will type a product name, OR size, OR whatever, he must get results only for the Construction or Non-construction. The user must not get results for the Food. And the user can make misspelling of words in the search, so the Search box must tackle it. And yes, the results should appear on the rich text box on the form itself.What is the code of doing the Search according the criteria above? All I know I have made a srteamreader code but when clicking on the search button, it is giving me all the texts i wrote in the text files. However, I want only some lines to be read.

What is the best method to get towards the end of a file in a Stream Reader. In my case, I have data at the end I want, but the rest of the data I don't need. If the file is very large instead of reading line by line until eof, is there a better way to get to the end?

I am reading data from an API feed and saving the chunks into files. When the files reach 2 MB I start a new file and write to that file. What happens now is that an entry (<entry></entry>) can get cut off at the end of a file and continues into the new file. I try and reconstruct the files by taking the last entry and combining it with the first entry of the next file but this is tedious handling the data transmission and file creation.
Do
timestamp = DateTime.Now
numbytesread = responseStream.Read(bufferread, 0, BUFFER_SIZE)
If numbytesread > 123 Then
'timestamp = DateTime.Now
responseData = Encoding.UTF8.GetString
