Can Regular Expression be used of this purpose? It's okay if they're in separate function, but I need to somehow get the counts of each of the above.

What I would like to be able to do, is to search for Pharaoh (any word) in a textbox, click the Search Button, and every occurrence of Pharaoh (not just the word, but the entire Verse: EX: Gen Ch7:14 Blah Blah Blah Pharaoh Blah Blah. Gen Ch9 :3 Blah Pharaoh Blah); to display inside a RTF or TextBox.
Below is what I've been using. While it does work, my program locks up when trying to count a rather large file, say 10,000 or more lines. Smaller files run in no time. Is there a better or should I say faster way to count the lines in a text file?

I have a whole bunch of files, which I would need to search for error codes and # of instances it occured. I tried ReadAllLines of File.IO but that just gives # of lines. How would we search for string within a file and count its instances?
View 4 RepliesCan anyone think how to read how many lines will be written to a txt file via streamwriter?I know i can do a count and increment on each writeline but maybe someone knows how to countlines from streamwriter?
View 2 RepliesBasically, every time an entry is made - all of the proper data gets put out to a central Listings.txt file and then a specific .txt file for that area. When the user enters the recall form, they can view the listings for all or whichever area they've selected. That works quite fine. However! We also need to include a summary of how many are in each section. Not thinking properly, I started to do this with a counter - until I realized that a counter will lose its value once the program shuts down. My current idea is to count the number of lines in the text file (it outputs 8 lines per listing, so everything would be in values of 8) and then divide that by 8 - but after some searching I haven't been able to find a piece of code that will allow me to get an integer that relates to the amount of individual lines in the file.

I have a an application that opens a SQL connection and over the course of a few hours creates and disposes of tens of thousands of DataReader objects. You could look at it as just one big loop. As the time goes by, the memory usage steadily climbs until the application/system runs out of memory and crashes.
Psuedo code would look something like
SQLConnection.Connect
Do Until x =1000000
Create New DataReader
Use DataReader
Close DataReader
[Code] .....
Even though I dispose of the DataReader object when I am done with it, the memory usage keeps climbing. I found that every time I am finished with the DataReader I have to close the SQLConnection and dispose of it. When I do that it keeps the memory usage very low and the processor usage is barely noticeable. I would think I could just open the SQL connection once and close it when I am done.

What you see here, is a code that picks everything written in between > and < markers from a source code on a website. What it returns is always a time stamp in between 00:00 and 23:59 and a string. Or almost always. There is a few instances where there are two times in a row and not every other, effectively breaking the system.Also, when this happens, the first time of the two has a "-" after it, i.e 18:00- What I've been trying to do, is making the program recognize when there is an extra character (the -), delete the extra character, and then jump over the next result in the search (the following time). This would completely resolve the problem.
The thing is, no matter how much I go through it in my head, I can't seem to think of a way to affect the NEXT result without screwing up the current result or all the following results. As you can see, my code is faulty. What it does now is an emergency method (as my teacher review of the code is coming up real soon) it jumps over the time with the extra character, and lists the following time. This however is not ultimately wanted, because in the bigger scheme of things, it displays the incorrect time for the incorrect string.
Search variable holds all the results of the regex search, for easier handling, and is used for checking for the extra character.Length6 variable is boolean for determining if the result had the "-" or not. The column ariable is to list the time and the string on the same line in the textbox.Jump is the variable that makes the code skip the conditioned result from the search.The counter variable, that might seem extra, is just for extra conditioning, its use is to prevent the first 337 instances of the search.
I wan't a method with which to find a string within another string. It should return the position of the first occurrence of the substring. (In VB 2008 !)
View 2 RepliesI need to find the first occurrence of a certain word's position in a textbox, on how to do this? Once I find out how I can get the position of the word i am searching for I can then pull the data I need from the textbox. I am using visual studio 2010 / visual basic.Since I have no clue where to start on this code, I will post what code i will be using to get rid of the data i don't need from the textbox.
Dim s As String = TextBox1.Text TextBox1.Text = (TextBox1.Text.Remove(450))i figure I can do this in a few steps to bring the searched info out of the textbox. I am open to other ideas on how to gather my data from the file or textbox. Here is what I have to do: Pull all of the players names from a replay file and put them in separate text boxes or even a listbox.
