I'm creating a certain number of objects based on some templates that I have available to the user. Then, I have a module created for each template where I will be doing some math operations, etc.
I know how many objects will be created, but of course visual studio doesn't at design time.

I can usually find the answers to most of my questions via the Google Gods, but not this time.I have a form that has a TabPageControl and on that page a collection of labels and text boxes via a usercontrol.
On the form I have a button that allows the user to create a new tabpage, when the code adds a new page, it automatically adds the UserControl collection. I can't get my head around how to access the objects on the newly created tabpage.
What I need to be able todo is take the index of the tabpage that has focus and translate that against the UerContol name, but I havn't a clue how to do it!

I dynamically (by programming text, not drawing in GUI) created a matrix of 10x10 buttons named 'Button1' till 'Button100'. In a formula I calculate a number, say '87'. If I next want to reference 'Button87' and change e.g. the background clolor and text properties, how would I do that? I am creating a PocketPC game using VB2005.

View 4 RepliesFor school and other reasons, i am making an application in which the user can draw tile based backgrounds, to then turn into long line of code , i think called CSV , which can then be used in programs such as flash, to draw a tile based background. I am currently making a flash game, and dont really like the other tile array making programs out there.
For instance, code such as [1,0,1],[0,1,0],[1,0,1] with the correct code would generate a 3x3 tile background with an X shape.Anyway, at the moment i am currently stuck.I have code up and running which generates a 2 dimensional background out of pictureboxes randomly, however thats as far as i got, i dont know how to access the pictureboxes created.
What i have right now is two variables, gridX and gridY, which determine the amount of tiles placed in a for loop. These variables would be used to determine the size of multidimensional arrays that store the tile data, and determine the map size.i intended each image to be clickable, so that its picture would change from black to white when clicked
When clicked, the tile would switch between two images, to represent two different tiles. at the same time, a value in an array created with the tile, would change from 1 to 0.Then when its time to make the code, i simply use a for loop to spit out the array in the way i want.
I understand that i could perhaps create a class for the pictureboxes, but i dont know how to, since ive never dealt with them, and i dont understand any of the guides and tuts.how to use a class so that i could add and change the properties of multiple dynamically created pictureboxes, but also change the value of an array created with the picturebox, when clicked?
i need all of this to be done however without adding or including any additional libraries or anything to visual basic as it will be graded on school computers.
I had created another thread asking how to create OvalShapes during runtime... Ok, so I have that covered, but what I need to know how to add properties to these OvalShapes individually. The OvalShapes are stored in the List(Of OvalShapes) if I create a loop from 0 to the length of the list it modifies all the OvalShapes with the same propertiesWhat I�m trying to do is make like 5-10 balls collide, this is why I need these properties to be individual to each OvalShape.

As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?

I have create a small routine to Generate Tabpages on a tabcontrol, and on each tabpage I have Created a label and a combobox, my problem is that since Im generating them in the code and the name of the two controls change based on an index.. ie.

View 8 RepliesIn C# I'm calling a function on an interop class (Connection, written in VB6), which itself returns a plain object (System). Then there's a function on that object (InitialiseData) that I also call (even though the compiler isn't aware of it). var isInitialised = Connection.System.InitialiseData(path); The problem is, because that System object is returning a mere Object, I get the compile error "cannot resolve symbol".

View 3 RepliesMy current project involves displaying questions/answers from two different databases to be used to compare values and make judgements. The number of questions, choices, and answers is all variable. Thus I am attempting to create labels dynamically to show the information on the screen and create textboxes to leave comments. My problem is not knowing how to then access these lables, since I can't code in to use "label_comments" & (i) as it doesn't exist (at least, I can't get it to work).
First, my code for creating and displaying the information:
db_connection = New SqlConnection(ConfigurationSettings.AppSettings("ConnectionStringMerrill3"))
db_connection.Open()
[Code].....
My process is as follows:I access a database table to determine what questions to ask (20-100 questions).Each question is display along with, possibly, a "done" button.My code to do this is as follows:
If datareader("Who_Second").ToString = lbl_Your_Position.Text Then
Dim b1 As New ImageButton
b1.ID = "btn_second" & datareader("QCC_Q_ID").ToString
[code]....
What I need to do for each button is strip out what the "QCC_Q_ID" is for that button and insert information into another table of the DB.My partial code for this is as follows:
Sub btn_done_clicked(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs)
Dim MyDate As Date
Dim QCC_Q_ID, Position As String
[code]....
Two problems:1. My sub is never being called, so I can only assume that my "addhandler" is not working.2. QCC_Q_ID = e.ToString.... That doesn't seem right - is it? What I need to do is get the name of the button (btn_second13) and get just the number out of that (13). Is there any easier way to keep track of that ID?

Using ASP.Net MVC1 and am dynamically creating the html in a model that is then dropped into the view and rendered at run time.
My view is a single page that looks like this:
<%@ Page Language="VB" Inherits="System.Web.Mvc.ViewPage" %>
<%=(ViewData("Content"))%>
This dynamically created content is mostly dropdownlist boxes in the format of
<form method=post action="/questions/nextBatch">
<div id="text">What is your preferred drink?</div>
<select>
[Code]....
Is it is possible to perform validation on the dropdowns lists to ensure that a value has been selected? If any of the dropdownlists that still have the default value (the "please make a selection" text) the page is then redisplayed with the font colour of the question or dropdownlist box changed to say red?
I'm from the Webforms world and have made the switch over to MVC (which I really like!) and I know there are some pretty slick validation tools out there but you seem to have to account for them within the view itself.
I cannot pass a HTML helper through the viewdata of the controller as it does not render unless it has been coded directly into the view itself.
Also, I'm looking for a pure asp.net solution as I cannot use javascript due to accessiblity concerns. I can access all the values of the dropdowns without any problems throug the formscollection object but from there I'm a bit stuck.
I have added Following HTML in the Form:
<asp:Table runat="server" ID="tblFlightDetails">
<asp:TableRow>
<asp:TableCell CssClass="ASPTableHeader">
<dx:ASPxLabel runat="server" ID="lblFrom" Text="From" CssClass="LabelFont"></dx:ASPxLabel>
</asp:TableCell>
