this is what I've got so far:
Dim find As String
Dim search
find = InputBox("Enter Search Text")
search = MyRichTextBoxEx1.Find(find)
[code].....
But how can i search for the next occurrence of the search?
My app is a Reader for personal use. I have it setup By Books of the Bible and by Chapters and verses.
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.

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 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.

A little background... I'm trying to build a spell checking form. I have this lovely library: [URL] and it seems to be working flawlessly.
The problem I have is trying to replace an entire word and only the first occurence of the word.
Example: Replace the first instance of "foo" with "bar" in the following string
"foo foo foobar" and get this "bar foo foobar"
I've been trying regular expressions with no luck. Here are the patterns I've tried compiling(these are obviously tied to variables in my program):
"(?<!foo)foo"
"(foo){1}"
I also tried the built in string.replace method with a count parameter, but I have no idea how I would make that match the entire word.
I have my program set up to download a web page with a webclient. Normally, I could just use .Substring, but there are about 25 things I need to pluck out of this page, and .Substring, or at least the way I have it set up, takes the first occurrence. The good news is, they are all URLs; they are all similar too.
Each URL is as follows: [URL]
Now, of course, this URL is just made up, but each URL starts with [URL] and ends with 'video'.
How can I hook this up so that it scans the entire page (contained in a string, read from a StreamReader connected to a WebClient), finds each URL, and then adds it to a listview?
I'm building an Outlook add-in in Visual Studio 2010, using VSTO with VB.net, to sync Outlook Calendar data with an internal, proprietary Calendar. Our users want to be able to open a recurring appointment in Outlook, send the Appointment details and have the internal calendar update with the recurring appointment details. I actually have code in place that works just fine for creating recurring appointments and single appointments. The problem is that I can see no difference (when viewing the AppointmentItem or RecurrenceItem members) between a single occurrence of the series being opened, or if the entire series has been opened; all the data is the same, all the functions have the same result. I can see there's the difference in menu bars, but I don't even see a way to detect that difference.

how to add and remove entries from a database and now I need to know how to search it. I'm going to be scanning a directory and subdirectories and adding all files found to the database. I need to check if the file has already been entered into the database before adding it.
I though it'd be simple and would just require looping though each entry and checking the item for each entry. I played around with a while loop a bit and ran into some problems. Like when the database is empty.
I don't want to half-ass some code that seems to work, since that'd probably be slow and inefficient.
Also what are the technical terms for a column and row in a database. I'd to use the proper terms in the future.
