Right now im using code to count the instances of certain letters in column named "status" the problem is i use a filter to filter them by the date they were entered, but the counter gets ALL the instances in the DB not just the ones displayed in the datagridview.[code]...

QuoteWrite a Visual Basic Console Application which executes a Do-While loop repetitively. Each time the Do-While loop executes input a String value, count and display the number of occurrences of the letters �a�, �b�, �c�, �d� and �e�. Use at least one Select Case statement inside your Do-While loop. For example, suppose during one execution of the Do-While loop you input the following String value: �My mother is a great lady!�. Your program should input this value into a String variable, compute the number of times each of the letters �a�, �b�, �c�, �d� and �e� occurs and output the results: a � 3, b � 0, c � 0, d � 1, and e � 2. Terminate your Do-While loop once a value of �All Done!� is entered for the String value.
Here is my code:
Dim s1 As String
Dim a, b, c, d, e, count As Integer
Do While (s1 <> "all done")

My problem is an error that states Variable 'count' hides a variable in an enclosing block. Here is my project and my code so far:
1. Write a Visual Basic Console Application which executes a Do-While loop repetitively. Each time the Do-While loop executes input a String value, count and display the number of occurrences of the letters �a�, �b�, �c�, �d� and �e�. Use at least one Select Case statement inside your Do-While loop. For example, suppose during one execution of the Do-While loop you input the following String value: �My mother is a great lady!�. Your program should input this value into a String variable, compute the number of times each of the letters �a�, �b�, �c�, �d� and �e� occurs and output the results: a � 3, b � 0, c � 0, d � 1, and e � 2. Terminate your Do-While loop once a value of �All Done!� is entered for the String value.
2. In the same Visual Basic Console Application, following the Do-While loop described in step 1. above, enter another String value and modify it by replacing all occurrences of the word �hi� with �hello�; all occurrences of the word �today� with the word �tomorrow�; all occurrences of �hate� with �love�. Output both the original String value and the modified String value.
This is my code:
Module Module1
Sub Main()
Dim s1 As String
Dim a As Integer = 0
Dim b As Integer = 0

I have encrypted a string to something like this:
1. Asak2$)kla1015QAXKFskfa332aSJ2(Ska@Skljcmcel3p.lq,aowpqaskla2@)Skx.:Pdm^),dfs;
what i want to is convert this string to something like this
2. JXK2LB AP2WXB S1P0XE ZXPA3H X1LAKW DOXPS3
both 1 & 2 the above strings are fictitious (i made them up to make my point clear)
I am trying to make a licensing system for my VB 2010 express application. (2) above will act as a serial key which can be derived from (1) which is an encrypted form of something unique of the client computer.
I will then confirm the (2) from the client.

I'm wondering is there a way to count the characters on a line like .length but with XML in VB. Take a look at my code and you'll probably understand exactly what im doing.Basically the formula is to count words by saying every 5 characters is a word. So I need to get the amount of characters in the line and divide by 5.[code]

I have a RTB which I import with a set of 7 or 9 didit numbers, 7 for Staff and 9 for Students. e.g. Staff numbers [code]and depending on what is selected in a list box ('Student' or 'Staff') will generate a string to create user accounts. To further error check I would like to check if a line in the RTB = 7 And Listbox = "Student" Then msgbox("Data mismatch between User ID and Account type")

I'm keeping track of some things that are numbered and others that are lettered; while NumericUpDown is perfect for selecting numbered things, I need an analogue for selecting lettered things. The obvious choice would be a listbox that just contains all the letters of the alphabet. But I need to show only the appropriate range of letters, so if I want to use a listbox, I need to write a function that populates the listbox with the first n letters of the alphabet; if n > 26, it should continue with aa, ab, and so on. How do I do this?

Why would a .sln solution file open and appear empty in Microsoft Visual Basic 2010 Express - i.e. no windows showing projects and code files etc.When I inspect the file in a text editor, it contains references to vbproj files (which are present) which indicate that it should not appear as empty.No error messages are reported when the file is opened.

I've noticed that when you click on a web page in Windows Explorer, or open a file in general, and the default application to open it is internet explorer, ie opens and opens the file. However, when I tried this on my Web Browser it opened, but ignored the file and went on its usual routine. How can I get my Web Browser to open and open the file that was clicked on in explorer?

I saved a file with the extension .doc. I use the RichText to write and save the text. I did not set any encoding type when I saved it. When I tried to open the file in the Richtextbox again, I got all the formatting characters in the RTF file. How do I correct this? How do I open and re-open a .doc file in the Rich Text box control without the formatting showing up in the box with the document contents?
