Find All Instances Of A Letter If It Appeared Multiple Times In A Word?
Apr 19, 2011
How would I find all instances of a letter if it appeared multiple times in a word? For example if I had the word 'mississippi', how would I find every 's' or every 'i' or every 'p'?
I know how to use the string.IndexOfMethod() so I was thinking I could find the first letter, mark that position, and search again from there. Then I would keep looping until the end of the letter. But I'm not sure how to signal the end of the loop.

txtSubject1Info.SelectionStart = txtSubject1Info.Find("Hey!")
I am finding specific words in the RichTextBox (in this case, "Hey!") and selecting them by getting their initial position through the "Find" command. Unfortunately, this does not work when I have multiple instances of "Hey!" in the RichTextBox. Here's an example:
Text in RichTextBox:
Hey! This is cool!
The Find command would return a value of 0 in this case. However, let's take a look at another scenario:
Text in RichTextBox:
In this case, the Find command would return a value of 0 again, but I want it to get the initial position of the second "Hey!" statement. I'm wondering how I can do this.

this is my first post in this forum! I guess my question is very simple. I just started with VB.net yesterday I want to search through a text string, and then count how many times a word appears. How do i do this? Is there some sort of function that i can use together with a loop of a kind?Something like the inStr(), just something i can use with mulitble appearences!

I am trying to check each letter of a word if that word doesn't contain (AEIOUY) then I have to append (-way) to the end of the word. Now I have this if statement and it doesn't work:
If OriginalWord.ToUpper Like "*[!AEIOUY]*" Then
Label1.Text = OriginalWord & "-way"
End If
I need to append a (-way) to the end of a word that doesn't have (AEIOUY)

I have just started using vb.net and I have a checked list box with times throughout the day shown as
00:00 - 00:14
00:15 - 00:29
00:30 - 00:44
00:45 - 00:59
What I am trying to find is a way to get the current time and find which list item it fits into. What I think I need to do is to first of all get the current time and then go through the list splitting each item into 2 times and seeing if the current time fits. For example: Split the item 00:00 - 00:14 to 00:00 and 00:14 and then check if the current time is more than 00:00:00 but less than 00:14:59 and if so do certain task.how to go about taking each list item and splitting it into 2 separate times so I can check between them?

My question is how to check a letter exist in a word. For example this word: 'computer' and I give in a textbox letter 'a' then the result will be false because 'computer' doesn't exist a letter 'a' else if I give letter 'c' the result will be true because computer has a 'c'.

I'm using Visual Studio 2008 writing a Windows Forms project and I'd like to know a way to step around 'default instances' of forms. I don't like default instances, they constantly get in my way, and working in a team it's causing some really annoying confusion about the object identity of which form is actual in focus at this moment. This means I need to go threw the entire project (big) and remove ALL references to any 'default instance' of a form. But this is difficult to do as there's no errors or anything, it basically requires me to search for every text of "MyFormType." and then checking if it's accessing a default instance and fix it like that.
It'd be nice if I could just turn it off or something so I could
1) easily find all erroneous lines of code
2) avoid the accidental use of it in the future by anyone on the team

Any best method of managing multiple SQL connections .net (VB). My application connects to four instances of SQL Server (2000, 2005, 2008, 2008R2) restoring databases, modifying data and taking backups. In addition to managing databases the app also has its own DB (on the 2008 instance) for storing various data. I'm using two methods to connect to the instances, SMO (For backups, restoring and retrieving information about the databases, size etc) and SqlClient for querying each database for many tasks such as updating fields and executing sql scripts.I have multiple forms for performing various tasks so there are many places I'm opening / closing connections.
Would it be best to maintain a persistent global connection to each instance from the application? (Two in total, one for SMO and the other for SqlClient) or open close a connection for each task I'm performing?) I'm not using LINK as I need the tasks to be as fast as possible. The connection string will differ on each connection (Based on Instance and Database being connected to) how would I manage this? A string in the config file for the applications database would make sense, as that would be static but the databases being worked on will vary with each connection. Currently I'm creating a connection for each instance within the main form:
Dim 2000Connection = New SqlConnection("Data Source=" & SQLServerName & _
"SQL2000;Initial Catalog=Master;User ID=sa;Password=P@ssw0rd;Pooling=True;")
Dim 2005Connection = New SqlConnection("Data Source=" & SQLServerName & _
"SQL2005;Initial Catalog=Master;User ID=sa;Password=P@ssw0rd;Pooling=True;")
Dim 2008Connection = New SqlConnection("Data Source=" & SQLServerName & _
"SQL2008;Initial Catalog=Master;User ID=sa;Password=P@ssw0rd;Pooling=True;")

I have the following problem. (VB.Net 2008)I have created a class (myFirstClass). In this class there are a lot of calculations being made wich gets fired by events in that same class.Now i want that same class to be able to fire more instances of itself. However i noticed that each time i fire an event from a Sub the program waits till the event is finished before going to the next line of code. This is a problem since i want the event wich fires a new instance of the class to fire it and forget about it.
