VS 2008 : Affecting The Next Occurrence In A For Loop?

Nov 16, 2009

Dim t As String = source
For Each m As System.Text.RegularExpressions.Match In System.Text.RegularExpressions.Regex.Matches(t, ">.*?<")
search = m.Value.Substring(1).Remove(m.Value.Length - 2)
If search = "" Or haku = " " And counter < 337 Then

[code]....

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 am having difficulties with getting a PictureBox to resize its contents properly. I have read through my code, and cannot find any issues.

Target CPU Affecting Execution Time Dramatically?

Aug 13, 2010

Recently, I've been running some tests with C++ and VB.NET to compare execution speeds. In the last thread I posted, I talked about how I had encountered the fact that C++ was executing just as fast as VB, but got that issue resolved. Now I'm hitting my head against another wall:I had made a DLL for VB.NET to test out this theory and compare in just one program side by side execution time of identical VB.NET and C++ code. But the interesting thing? VB.NET's execution time improved such that it was now exactly identical to the execution time of C++. Spending some time with the problem, I discovered that the "Target CPU" option in advanced compile options in Visual Studio 2008 was the culprit!

Since I'm running 64-bit Windows 7, I figured making the target CPU x64 would yield the best execution time. Wrong. Here are the results in execution time of a Windows Forms application for VB.NET,calculating all the prime numbers up to 10,000,000 and getting their sum.

Any CPU: 15.231 seconds
x86: 10.858 seconds
x64: 15.236 seconds

Below is the code I'm using, feel free to test it yourself:Public Class Form1

VS 2005 - Odd Occurrence With SQL Connection

Apr 17, 2010

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.

Find The First Occurrence Of A Certain Word's Position In A Textbo?

Nov 15, 2011

I 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.

VS 2010 Replace First Occurrence Of An Entire Word?

Jul 19, 2011

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.

VS 2010 Taking Out Every Similar Occurrence In A String

May 7, 2012

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?

Determine If Outlook Appointment Opened As Single Occurrence Or Series?

Feb 27, 2012

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.

Evaluates Loop Condition In Do...Loop Statment To Determine Whether Loop Instructions Should Be Processed

Mar 14, 2011

Makes the following statement about the code below:

**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.

Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?

See below.

Option Strict On
