Im programming a simple console application for the hell of it that performs a simple encryption on a string entered by the user. The encryption is simply swapping the 2 adjacent letters throughout the string. i.e encryption would become nercpyitno.
View 2 RepliesI've set up a test database to begin unit-testing an app that I've recently been added to. It is a 3-tier design (presentation layer, BOL and DAL) and this is my first time writing unit tests. I've decided to start at the BOL and I figure the best way is to swap out the ConnectionString (which has been passed along as a Shared String) with one that points to my new test database. However, I don't wish to change any production code. I simply wish to somehow redirect the app to the test database during unit tests.

View 2 RepliesI'm trying remove non-letters from this string I have. I have an order form for hats and T-shirts, they select everything and click on buy button there order info shows up in a listbox. For the results in the listbox I break down there order info and show there total price. Well the string I have for the sizes comes up with Medium "7 1/8 - 7 1/4" in the list box. I want to remove non-letters and have it just show "Medium". I try using the instr function and the trim function as well but nothing is happening.
View 1 RepliesThis seems a simple enough thing to to but its giving me problems. What I have is this; a text box the user enters a word into, then a btnReverse that when clicked should cause the inputted word to display in reverse in lblReverse.Text.

Option Explicit On
Option Strict On
Option Infer Off

I have a string of randomly organized characters and I am trying to search a wordlist for matches. If the wordlist has a match I want it to add it to a listview. I wasn't for sure how to word the first two sentences and I think an example will help explainmy problem better. So here is an example. I have a textbox where you input what you want to search for in the wordlist. Lets say you type in tca . The wordlist contains cat frog dog , each word on a separate line. What i want to do is take what you typed in the textbox, tca , and find the word cat in the wordlist.

So I basically want to make sure that a string entered by the user is valid. Valid being over 10 characters, containing only upper case characters, and only characters A - Z and spaces. The first two were easy, but I'm having trouble with the third, though.What I originally attempted to do was create a loop which checks if the first invalid character is present with the InStr function, by using the characters ASCII value. The next ASCII value is then checked, and so on until it has checked the string for every single invalid character. If an invalid character gets picked up, 1 is added to a variable, and after the loop is finished executing, if the variable is no longer 0, invalid characters have been detected.
View 3 RepliesI am making a question and answer game, and I would like to be able to give the user some slack in the answers if they were to misspell a word by a letter or two, like if the answers was Jumps and they type Jump if you did a comparison of them like If string1 = sring2 then do whatever, but obliviously those to string dont match, so it would return false, even though it is the right answer, I came up with this routine to compare two words and if the percentage of the letters are higher then 82 % right it will give you credit for your answer.

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

View 1 Replieshow do you search a string for capital letters, is there a function I can use to return to me how many capital letters are in a string? I have tried searching this but as yet not stumbled across a function. Most functions I found converted lower case to upper case Etc. I thought InStr might be the one but still looking for information on that one. I did find something along the lines of .char.isupper but the textbox is .text A password 'rating' tool of sorts of which I use a counter so if I enter "STRing" in the textbox for example it will return a 3 add it to the counter and continue with the little algorithm which my rater uses to add up things such as numbers or special characters to get a final score and that indicates to the user how strong the password is.
View 2 RepliesI was trying to use the ToolTip class as shown in the sample code below.
errorToolTip.Show(toolTipValue, control, (control.Location.X + control.Width) / 15, (control.Location.Y / 15) , 4000)
To place the tooltip adjacent to textbox object.
Problem is: the above code is placing the tool tip text in the correct location for few textbox controls and in wrong location for few textbox controls.
Information:
1. Application was in VB6 earlier and is mirgrated to .NET now.
2. All the forms in the application are UserControls embedded in WindowsForm.
3. In the above code, X and Y locations, I am converting them from Twips to Pixels.
How to manage to have the tooltip text exactly adjacent to the textbox control for all?
I made a small license generator app with a datetimepicker, a textbox and a button on the form. When I ran the app and clicked the button to generate a license I got - 16DDD-06DDDD-09DDDDD, and each subsequent button click would get me a license with a different generated character (16444-064444-0944444, etc...).
I thought this was unusual as it should be generating a random character not a repeating one, so I stepped through in debug and the characters generated were random (161g2-06T5ip-0957H9k). I thought perhaps that I needed to seed the value with Now().Milliseconds, no luck, that still resulted in repeating characters. So I tried sleeping the thread and that generated the random values I wanted.

View 1 RepliesI'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?
