Adding Stack Elements To Labels?
Feb 15, 2012
I am trying to add (Push) whatever the user enters in (MyStack) into 5 different labels that should show the (UserResponse). The problem is I don't know how to display each element in a different label. For example:
- The first element that the user enters (UserResponse) should be in Label1
- The second element that the user enters (UserResponse) should be in Label2 etc.... up to label5.
Also, when I press (Pop) the elements should disappear (Last in first out).

I am trying (Push)add data into my stack (length of five) and (Pop)delete from the end of my stack.
I need to know how can:
- Add the elements to the stack with keeping track of adding and deleting from it (adding an element will increment until 5 and deleting would decrement until the stack is empty).
Private Sub Button1Push_Click(sender As System.Object, e As System.EventArgs) Handles Button1Push.Click

I am just starting VB at 60 years old and with no programming experience and nobody to ask for help...except here, of course. So needless to say I am hitting brickwalls. I am using "Murach's Visual Basic 2008" and it seems to be a good book. This is what I am up to I have to declare an array with 5 elements with an index. I think that part is OK. Then add code that adds each element to the next one every time a user clicks a button. I have had many tries but the best I can get is just the grand total of the elements. Here is the code I came up with:-
[Code]...
Is anyone able to show me how the button click would reveal a progressive total of the elements each time a user clicked on it? It would be good if the book came with answers or had a forum for their readers.

I have an array x in size of objects (between 1 and 100) and I want to increase the size to 101 ... I've resized the array and that adds the objects but unfortunatly (not suprising) the added items have not been initialised, do I've reverted to using a do while loop and adding the elements indiviually, but looking at the code around it where addrange is used extensivily, I was just wondering if that was a neat vb.net way of doing the same thing
Bit of a learning question, just looking for neat ways to do the same thing

I have some combo boxes on a form and I want to add some elements into them . Practically I have to add "1" , "2" ..... "100" .
I can use this code :
ComboBoxMY.Items.Add("1")
ComboBoxMY.Items.Add("2")
...
ComboBoxMY.Items.Add("100")
but this will take too many lines . Of course I can accept that , but I just wonder if I could write them with less code .

So I have a dropdown setup on the page called ddlVehicleType that is populated from a store. This method gets called when another dropdown is changed, and it's supposed to remove all items from the aforementioned store, re-add them as needed, and then populate the dropdown with the new values.
It's doing everything it's supposed to EXCEPT clearing the store before it re-adds the values, so the result is, when I switch, I'm getting what it used to be PLUS the new values that should be in there by themselves.[code]...

I have to design a project for my IT course at college using Visual Basic. The task is to create a program which allows the user to enter the height of a room plus the width of the walls as well as the paint which costs different prices. I have managed to get the program to work out the cost of painting each wall, but I cannot get another label to show the price for painting a full room, when the result is basically adding up the cost of painting all of the walls. how to add up multiple values displayed in labels?

The three labels "Floor" "Typ." "HeadsI can insert once fine but multiple times only the third instance is written to the form.I have 2 textboxes to test that the Label.Name is changed but I can't make the Label.text stand for each label. I am certain this will occur too with the textboxes.I also need to keep track of these boxes for further use with the program.

I have a simple poker game that deals out 9 cards into pictureboxes and shows another 3 pictureboxes that hold cards for the dealer. The code itself does what I want it to...even though I'm at a dead end with writing the code further to evaluate the poker hands. I would simply like to add a few labels and a combobox to my form, but everytime I add something, or try to add it I get cast error?

I've made a user control and have added some internal labels inside it. In the User control class I'm trying to handle the mouse events so that: When the mouse enters the User-Control the background of the User-Control turns white - using MouseEnter event. When the mouse leaves the User-Control the background of the User-Control turns grey - using MouseLeave event. However as soon as I move the mouse over the internal labels it triggers the MouseLeave event. I don't want it to do that, because the mouse hasn't left the bounds of the User-Control! So, how do I get it to not trigger the MouseLeave event when the mouse is still internal to the User-Control?

I need to read an xml document from a database record into an XDocument object in order for it to be deserialized. So that the deserialization will work, I need to apply a specific namespace to each of the level 1 elements. So XML looks a bit like this:
[Code]...
How do I prevent the blank/empty namespace being added to each child element of the element to which the required namespace has been applied?

I created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript.

Apparently I don't understand what PointToScreen() is actually returning. I'm thinking it should be absolute screen co-ordinates. In a form, I have some labels in a panel, which itself is in a panel and am trying to derive the screen co-ordinates for the labels in one statement without adding the X and Y co-ordinates of the panels. Why does PointToScreen(Label.Location) return the same value as PointToClient(Label.Location) and the same as Label.Location? Shouldn't PointToScreen() return absolute SCREEN co-odinates?

I created a program that has serval labels on a form and a listview object. It has a button that when clicked reads a textfile and loads up values in the listview object. I then can click and drag text from the listview box to any label on the form and then the program removes the value from the listview box. Now, my question is how can I instruct VB to save these values in the text property of the labels so that the next time the program is loaded the labels will contain the values loaded during the last run time session?

Well im currently developing an application for public use, I have a login screen in which the user enter's their registered credential's and the progressbar loads by increments of 3, now i placed 6 labels ontop of eachother and where the progressbar coding is i put:
If Progressbar.Value >= 1 Then
Label3.Show()
If Progressbar.Value >= 20 Then
Label3.Hide()
Label4.show()
And so on up until Label8 Show at 100%,
Now the problem is... As i have placed the labels ontop of eachother i need them hidden until they are called to show, i have tried adding a background worker to do this but have had no luck, all i see is the labels overlapping eachother when i run my application when i want them hidden untill Label3.Show() is called, and then to display them as they are called and hide them when another one is called to show...

With VB, but I've got the few basics down, file naming, adding objects, naming objetcs, etc. But the reason I'm on here is because I cannot complete even the first step. Our form is 640 X 480, and we need to have two labels, both have vertical scrolls. I know how to add and resize the labels to meet my needs, but I do not know how to create scrolling labels. Or are they text boxes? On our bubble chart (Do you know what that means?) it says lblInformation. We are going to have clickable radio buttons which will update the lblInformation with info about each of the radio buttons.

I'm trying to make a program that allows the user to click on labels which have a number in it and then that value has to be stored into a different label.
For example the user click on label1 and the values goes into label12, then it click on label3 and the values goes to label13 and so on.
At the moment I can only code on the respective label underneath (1->12,2->13...) but it has to be in any order (5->12,7->13...)
Here a picture and below my code:

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?

What 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.

I'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.

My 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.

I 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.

We have this funky little ObjectDisposedException happening now and again. But only on production machines, of course ... can't recreate the issue on my dev unit. So I trotted on out to the Microsoft site to see what members of this exception I could use to figure out what's going on. Microsoft says that one of the members is StackTrace. I double and triple checked that I'm looking at .Net 1.1 information as I'm pretty sure that's what I'm using (how can I check that?). Here's the page I found - [URL]
So I go back to my program to write something useful to the event log so I can figure out what's going on. And when I look at the members of the ObjectDisposedException available to me I only see the following: GetBaseException, GetType, InnerException, Message, ObjectName, ToString.
what happened to my StackTrace member? I sure could use it if I could figure out how to get to it.
