I'm trying to use a stack object to reverse the order of words (not letters) in a sentence. I'm fairly sure that the split and push methods are working, but I can only get the first word (i.e. the first word in the original sentence), to be displayed.
I have the following code:
Private Sub btnReverse_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnReverse.Click
Dim s As New Stack
[Code].....
I need to write a VB.NET code to reverse the given characters using a stack.Input: 'S','T','A','C','K' So far I have input the letters, but I don't know how to get the console to reverse it. I'm a beginner to programming so please excuse my ignorance.
Module Module1
Sub Main()
Dim StackObject As New Stack

View 5 RepliesI have two listboxes: lstStates and lstOuput
I have cut and paste the fifty states on one box in the order in which they entered the union. I have two buttons, one to alphabetize the states and one to reverse alphabetize the list. Here is the code for alphabetizing the list:
Private Sub btnAlpha_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAlpha.Click
lstOutput.Sorted = True

How can I put the list in reverse abc order without using an array? I've tried a variation of the above code, but it did not work?
Text is entered into a textbox form. Upon button click, the order of characters in the words in textbox.text string will be reversed. The order of the words themselves will stay the same. For example: "I Love Visual Basic 2010." will be converted into "I evoL lausiV cisaB .0102".

View 5 RepliesI hope that I'm not just overlooking something, but I am really struggling with working with an array. To simplify my issue: Suppose you type out the values: 1 through 5 into a textbox (1 2 3 4 5). I'm looking to convert that string to an array, so that I can reverse the order and then show the new order in the textbox.

I need to place objects of various types in a "collection" and be able to:
1) Change the value of a property on any of the objects by using it's key.
2) Read the objects in the order they were placed in the "collection"
3) Read the objects in the reverse order they were placed in the "collection"
My findings so far:
1) Collection won't work because Item property is read only
2) It seems that Hashtable and dictionary won't work because I cannot iterate through them in reverse order.
3) Stack won't work for obvious reasons.
Is there a collection like data structure that has satisfies the requirements?

In Visual Basic 2008 Express edition: Create a new string replacing the order of the words, from last one to the first one and show it in a text box..Example: Input: This is an example Output:example an is This..I know theres a function to reverse the letters (StrReverse), but the order of the words?

In VisualStudio 2008 VB Express edition, I specify the following comments:
''' <summary>
''' ...
''' </summary>
''' <remarks>
[Code]....
If I compile the file and examine the .xml, I see that the comments are being included in the reverse order to what I specify ie. Part3 appears before Part2 appears before Part1.
Additional behaviour: If inline comments are interspersed between the external includes, they are all written to the xml first and then the includes (in reverse order)!
let there be an option called 'Turn off unintuitive xml comment behaviour'

The text file words.txt contains a list of words. Write a program that displays the words in a list box sorted by the number of different vowels, they should be ordered first by their length(descending) and then alphabetically. The display should show both the word and the number of different vowels in the word.
So I have
Private Sub btnDisplay_click handles(...) btnDisplay.click
Dim Words() as string= io.file.readalllines("words.txt)
I can use for each word in words to check each word but I don't know how to check how many vowels are in each word or how to order them.
I am trying to do a bubble sort using arrays and i am trying to sort a word in its alphabetical order... and my problem is that. i could not assign a value into my array from my textbox and get the length of the word from the text box... i do have this alogorithm'dim asd () as string'asd() = Text1.text'Len(asd()) but it seems that it doesn't work that way as what i am thinking.how to do it? it has been bothering me for days now and even if i do a lot of library sessions for this but still i could not find what i want to know.
View 8 RepliesI need my VBA Macro to locate text throughout a document and move it. The information that needs moved can easily be detected by the font colors. For example:
"Celica Toyota": Toyota would always be a specific Green font and Celica would always be a specific blue. There can be more than one word in the range that needs swapped (ie: "Monte Carlo Chevrolet").
I have some really long drawn out code, but there's got to be something more efficiant.
I need to reverse a string of words without using the reverse function. This is what I have so far, BUT it only shows the last two letters. For example: if i type "John" it will only give me "ho"

I need to this without using things we haven't seen in class.
I recently started wondering about how Microsoft would go about checking the text and checking its color, word order (spell check), etc. and I was trying to think of how they would do it if they were forced to write something, like Word or the text editor in Visual Studio, in Visual Basic.NET. Ways that I thought of could be using an array, setting a string to a word in that array, and check if that word is in the text. However, after I tried it, I realized I had to set the .SelectionStart property to zero, which got annoying if the document was long. Also, with arrays, though I could store the strings in a text file and read from that, I was limited to the number of items I could have, and I'm sure it would get frustrating if I added or subtracted a word (then having to back in the code and replace all of the instances of that array.)
Then I started thinking about streams. Though I have not tried them yet, I would imagine that if they had to be used, the problem of speed would come up again. But what if the stream only checked say 30 characters before and after the current selection start? Well, that would solve the speed problem, but it would bring up another. Every time the caret position changed, (if we were checking for color changing) we would be limited to those 60 characters. Say the word is "hello". What if "hello" began 31 characters behind the current SelectionStart? "h" would remain the same color, but "ello" would turn the default color (this is because we would have to reset the color everytime just in case the user changed a certain word.)
I write an HTML file with MS Word, and use it on my application. The problem is that I need to close Word or Visual Studio in order to save the file, or compile the code, because each one reserves the file permission rights. The html file is only written by word, and only read from VS. At compile time, the file is copied to execution directory. Is there a way to give both programs simultaneous permission rights?

I have a combo box bound to a datasource. I need to change one combo box (of many) to order the items in descending order.I'm guessing I could order the collection in the dataset, but that will mean all my combo boxes will be reordered?
View 2 RepliesI have a databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2
But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?
I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.
This might not be so 'VB' as it is 'SQL using VB' I have an application with a built in MS Access DB.

In your actual programming experience, how did this knowledge of STACK and HEAP actually rescue you in real life? Any story from the trenches? Or is this concept good for filling up programming books and good for theory?
View 6 RepliesWhat I want to know is that in VB.net is it possible to get a stack overflow, and if so how is it caused. What I mean is, what sort of written code would cause a stack to overflow.
View 2 RepliesI've started using .Net's stack collection. The basic features I guess are the "pop" and "push", where you add or take off the top element of the stack (if you are referencing other elements in the stack then another collection type is probably better).[URL]..it appears that the Stack collection (like other collections) is basically an array with some window dressing (so you actually can see other elements). As far as I can tell, "popping" and "pushing" is changing the first element of the array. Shouldn't instead the final element be the "top" of the stack and be the one that is changed? Otherwise the program has to reindex all the other elements in the array every time a pop or push is made. This seems very inefficient. But this is what Microsoft's description appears to be saying what is happening.
View 10 RepliesMy problem is that i need log the stack call. I know that i can put a breakpoint in code and choose the debug menu option "call stack", But that is not a solution for me, because i need all the methods called by the application, not only the last until the breakpoint.
View 3 RepliesI just started programming in VB.NET 2008 with the Express edition and have been having a blast so far. I thought a fun program to try and make would be an infix to postfix program.
I have five text boxes off to the side of my program that shows what is on the stack as you iterate through the equation. I'm wondering if it's possible to make these textboxes set to display what is at a certain index of a stack.
For example, if I pushed a "(" onto the stack, I would like the top box of my textboxes to update and show a "(". When something else is pushed onto the stack, say a "/", I would like the "(" to be displayed in the second box down, and the "/" to be displayed in the top box now.
