I have read plenty websites and i can not find the solution...I dont know why, i have tried many algorithms and none of them work for me. Anyone knows where can i found some dynamic programming algorithm to solve the problem of the coin change?

i am trying to make a coin toss program where you toss a coin a certain number of times then repeat it a certain number of times. the problem i have is "heads(counter2)" the word "heads" has a blue error line under it how do i sort the error out and also is all the code right
Public Class Form1 Dim tosses, repeat, heads As Integer Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
I'm making a map engine for another game I'm working on.... I would like to make my mouse cursor be a 32X32 pixel rectangle. This would make it easier to place my tiles which are all 32x32.
the problem is about user when click button coin and it will display the decimal number and suppose to be like this : 0.10 also , i have made code about notes amount like RM 1.00 and RM 5.00. [code] the problem is when i run the program and click the button it become like this: RM 1.2 not RM 1.20.i also attach some pic in the first pic the coin appear normally but after i click button RM 1.00 , it become like second pic.
I have a map editor program for the rpg game engine I made and am trying to add an undo option into it. The map is stored in a class so i made a array of the class then added this code for when the map is changed [Code] but when i do this all the maps in the array get changed when the player edits the map.
My environment is VB6 (NOT .Net), and I have three function-similiar com+ DLLS with different GUID. For example, DLL A, DLL B and DLL C have the same function Beep(). I have a VB application, if I want to use DLL A Beep(), I should import the DLL A reference, and rebuild my application. If I want to switch to DLL B Beep(), I have to change the DLL reference and then rebuild my applicaton.. The same to do if I do with DLL C.
The code below is the entire class that has the error in it... the errored code is highlighted in red. The error is,'ReDim' cannot change the number of dimensions of an array.
Code: Public Class clsMap Dim SR As System.IO.StreamReader Public Width As Integer Public Height As Integer
I have an MS access database with some .dbf files linked to it. One of the dbf file is a sales file. I am trying to generate a report for each of the month's sales. For that the sales dbf file will be different for each of the month. I want to give an option to the user to specify the file name from which he wants to use to generate the report. After accepting the input from the user, i need to link to that table in MSACCESS. Is there a way to achieve this from vb.net
How would I change this code to make the factory dynamic. I believe I was close with remoting. I don't want any hardcoding of the factory, nor do I want to have to recompile. The database drives it.
Dim genericRule As Rule Dim factoryObject As String factoryObject = _dal.GetFactoryObject(ruleId)
how can i select these buttons in the program ?I can change the propertiies inside the click event because i know wicht button i pressed thru the sender of the event but i don't find a way to adress the other buttons outside the event.
please note that i am a beginner in programming in vb.net For i 0To 1 For y = 5
I've gotten this 75% completed but am now stuck on 2 separate, but seemingly "simple" fixes. I've written a coin tossing program that is supposed to give a "True" answer for heads and a "False" answer for tails as well as keep a running calculation of how many times heads and tails are shown. Additionally, there needs to be a picture that shows what side comes up. Right now, I have the "True/False" answers coming up correctly, but without any images. I've also verified that the images are in the Resource folder as well as verified that the "True/False" are correct by comparing it with the results in the heads and tails label that they show up in. I've tried to display an image(s) by embedding it as a resource in a project but it does not show up. The second problem is that the results in the labels show up as 1 & 0s, not a running tally as it should be.
Here's the code that I have: Public Class Form1 Dim randomObject As New Random() Private Sub tossButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tossButton.Click Dim headscount As Integer [Code] .....
I have also tested taking out the +1 on the If/EndIf statement, which then returns only 0's in the boxes with the "True/False" still working as it should.
I am working on a little project and am having some issues with a checkbox. I am adding a number of checkboxes to an ASP table via code by adding rows and columns dynamically. This all works fine except for when I go to check them based on loading a preexisting record. For some reason some of the checkboxes are getting set to TRUE when the new row is added to the table. [Code]
I am using some interesting code to perform dynamic unmanaged dll calling:[code]I want to be able to change the parameter signature and type of the delegate to void or to a function returning integer, string, or boolean.Basically, I want my program (interpreter) to be able to call upon any method in any unmanaged dll that the programmer has access to since I cannot predict what method the programmer will want to have access to - I'd like to enable them to have access to any useful method.[code]This raises a complaint on the line with 'Dim theResult = ' on it. The error is "Object of type 'System.Int32' cannot be converted to type 'System.Object[]'."
I have recently taken a liking to programming, and have programmed a few games in C#,my friend has asked me to program an application for him to use in his shop. But I have no idea of what language is best suitable?
I have writen the code so you put the number of times you want to flip the "coin" and into a label the results show. I want it to show the % instead of the number of times that the side lands on.
This is what I have so far:
Private Sub value(ByVal count As Integer, ByVal tailscount As Integer, ByVal headscount As Integer, ByVal flip As Integer) Dim FlipCount As Integer Dim strflip As String
i have created a dynamic tabpage and a dynamic tablelayoutpanel inside it then added dynamic textboxes and labels inside the tablelayoutpanel...the thing is , i am having a problem on how to access the value of those textboxes and labels and add them as new columns in the new table(tagpage) in mysql database, i can already create the table in the database but i cant add the new columns in it. heres the code for accessing the values of the labels and textboxes
error: NullReferenceException was unhandled....Object variable or With block variable not set.
Basically i have one TabControl with a form and 2 browsers within one form I have ProBlem To call the dynamic browser to navigate with dynamic Textbox.text
I need to represent the following query using LINQ:
DECLARE @PurchasedInventoryItemID Int = 2 DECLARE @PurchasedInventorySectionID Int = 0 DECLARE @PurchasedInventoryItem_PurchasingCategoryID Int = 3 DECLARE @PurchasedInventorySection_PurchasingCategoryID Int = 0
[code]....
Now, I know that a query in .NET doesnt look like this, this is my test in the SQL Design Studio. Naturally VB.NET variables will be used in place of the SQL local variables.My problem is this: All of the conditions after "WHERE" are optional. In that a query might be made that uses one, some, all, or none of the conditions. V.PropertyID and V.Value can also appear any number of times.In VB.NET I can make this query easy enough by simply concatenating strings, and using a loop to append the "V.PropertyID/V.Value" conditions.I can also make a Stored Procedure in MS SQL, which is easy enough.However, I want to accomplish this using LINQ.
Ive managed to dynamically create a form, and dynamically create a timer, but i have not been able to create the timer on the dynamic form. Specifically, i need to be able to have the timer itself create another form with a timer. (I realize that this would create a new form every interval on the timer, that is what i want to do)
1. A way to add the timer to the dynamic form, and maintain the timer sub on my main form.
2. A way to create the whole thing over (dynamic form and timer) through the previous dynamic form and timer.
I was thinking i could use a collection/array to store the forms and timers, but i'm still having trouble figuring out how to add entire forms or timers into a list. (A timer is not considered a control, so i cant use a controlcollection...)
Heres my code;
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim frm As New Form
[Code]....
*EDIT* Btw, my idea was to use i as a variable that increases every time a form is created, then insert the form into the array, with i as the integer. i just need to know how to create a new form with a different name each time. (as with timers)
I avidly create games in VB.net. Being a hobby programmer I give my games away for free. Since I'm a hobbiest without formal training I do try and educate myself on proper programming principles and follow them when programming such as OOP. There are however some things I have obviously missed being self-taught that perhaps I would know if I were formally educated. Once such issue that has really been my bane is how different classes (from now on referred to as objects) 'know' about each other WITHOUT programming specific interaction.
Okay imagine this, you have a space game and the following objects
[CODE]...............
Now each one of these objects has a Health, X,Y and Z private members and properties that are all inherited from clsSpaceEntity for argument sake. Now one way of programming collision between them would be to code out the following logic in the main game loop
[CODE].........................
Now this might seam okay if your talking about the simple example above but some of my games have tens or even HUNDREDS of objects that interact in this basic way. Is there a way in OOP to do the following... for each thing that inherits from clsSpaceEntity check against every other object that inherits this type (except itself) and if they collide then reduce health next? This sort of ability for a type of objects/class or whatever to be 'aware' of another and how they are the same/different and interact would save me tonnes and tonnes and TONNES of coding.
I have a form that i need to be 100% Dynamic. So it could contain 10 labels maybe 100 who knows.
When you hover over a label there will be a different contextmenustrip to appear for each and every label. So all the contextmenustrips are Dynamic and contain 1 option maybe 2 options even 3 or 4 up to the users settings.
My problem is not creating a handler for when the user clicks on the contextmenustrips options. The problem is knowing which one of the options for that contextmenu was clicked!!
OK, I'm trying to display tooltip text for a dynamic edit box. Well, at least I'm trying to.
On my form, I've got a tool tip control which I've conveniently named ToolTip. My edit box displays OK. But, what I want to do is when the user hovers their mouse over the text box, I want the tool tip to display some text.
I think there are two problems that I'm having. I'm not convinced that I'm properly addressing a dynamic text box name. Ideally, I would want to be able to refer to the text box (but using a dynamic variable that will contain the prefix of the name). To hardcode, I would want to be able to achieve (not in this example but in theory): ABCDEFGt_0300.Text = "hello"
Dim controllerName as string = "ABCDEFG" Dim t_0300 As New TextBox() Me.Controls.Add(t_0300)
I need to make a matching card game in VB 2010. i have generated my cards but now need to show the cards for 10 secs then change the cards to (AppPath & "Cards ed.png"). then when a user clicks on the card the card will flip over.*How would i set a timer to turn all my cards into*(AppPath & "Cards ed.png") after 10 secsbut still have the values from the array and when i click the cards they flip over (from red card to numbered card)
Code: Private Sub Place() Dim Counter As Integer = 1 For Row As Integer = 1 To Int_Grid_Size
I'm using Visual Studio 2010 / VB / dot net 4.0, and I have a drop-down menu in my left column that switches resource languages for the end user. It reads like this:
--------English ------- <<- Engish is always the default top language option French | Spanish |
