The trouble I'm having is working out a way to be able to call the objects in the dynamically created usercontrols. I thought a list maybe an option but I am struggling to get the syntax/get it working. Wondering if anyone has some ideas or different approaches..
I created an item user_control that has a textbox, button, etc. which will intentionally collect the total quantity of items the user wants.
I dynamically create a few intances of user_control on page_load. If you click the add button for the item quantity it will add to a session variable. however when the user enters a different quantity in the textbox and clicks the add button the total is of the original value of the textbox.
How to get the value the the user has typed in to the textbox to add to total???

I made a browser and its awesome but i want to reference the browser name so that i can add script to it, I am calling the new browser window "wb" cause that's what it gets named in the script. here is my code. (it labels the tab, the window, and changes the URL text field)
Private Sub wb_Navigated(ByVal sender As Object, ByVal e As System.Windows.Forms.WebBrowserNavigatedEventArgs) Handles wb.Navigated
TextBox1.Text = wb.Url.ToString()
Me.Text = CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).DocumentTitle & " - My Browser"
[code]....
It says "Browse.Name = "wb"" so thats why im trying to call it "wb". I inserted a WebBrowser on the form named wb and then tried to run it and it worked, it labeled the window, tab, and changed the URL field. So i know that the script works. Please help me, I know you guys can solve this, I'm really new at this.So my final question is... What should I call the browser instead of "wb" when I am referring to it in the first script I posted above? I am so confused. How do you refer to an object that gets created dynamically?
I've been wasting so much time on this. Basically I want to have a list of objects and I want to call some specific methods of some specific bjects..g.MsgBox(Instances(0).Position(0).ToString)It should alert a number that presents the X position, but it is not working... the box does not even appear and no errors.
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". I can see why, but the same thing works fine in VB.NET:

View 2 RepliesI have to ask my first question at some point, so here she goes.I am trying to create a dynamic list of objects. The objects will have several types (String, Integer) associated with them. Currently I am forming a Collection as I instantiate new objects.Is there a prefered to map this collection to, say, a Datagridview? Will I have to Iterate through the collection and add the rows at each iteration?Would I be better served using an ArrayList or something else over a Collection?

I am trying to create a form where depending on what the user selects, they are shown a collection of images from the web. Depending on what they select there will be a different amount of images so each picture will need to be added dynamically.
I am able to create PictureBoxes dynamically however I'm stumped how to create event handling in order for each control to give a unique response.This is what I originally tried but I got an error..
Private Sub Form1_Load
For i=0 To 10
Dim picBox As PictureBox

The error I got was
'AddressOf' operand must be the name of a method (without parentheses)
How ridiculous that you can't include arguments in your AddressOf! Can anyone shed some light on my situation (or knows a better way of carrying out my goal)?

I am relatively new to C# and winforms, although I have been using Java for years, so forgive me if im asking something relatively straightforward!I have a DataGridView, it needs to update regularly so I wish to provide a Collection of objects as its DataSource and NOT a database table.So far I have a List<MyObject> which will be constantly updated via a BackgroundWorker thread. I want my DataGridView to update when a change has been made to the List i.e. if the objects are resorted, added to or deleted from etc.Currently my DataGridView only displays the first object I add to the List, if I add more the DataGridView doesn't update to display the new objects added.This is a basic overview of how im coding it:
private List<MyObject> myList= new List<MyObject>();
myDataGridView.DataSource = myList;
Then my BackgroundWorker thread updates the list, e.g.

I'm not sure if this is a bad way of building an application but let's say I have 30 WPF Windows for different screens in my application. I want to build them into a DLL so I was wondering if it is bad design to instead of creating each window as a window, if i can have 1 window that hosts whichever screen is open. So the windows will actually be a usercontrol, or at least act like one. So when you want to go to a different screen, you would just change the content of the 1 window to the content of the "usercontrol" that you want displayed.
View 3 RepliesI am trying to troubleshoot a VB.NET project that contains UserControls (actually, several of them that are displaying the same issues). I am trying to get them to build under x64, but it is impossible. In x86 or AnyCPU, the UserControl builds and shows up in the Toolbox, so I can add or modify it in the forms that require it. In x64, the controls disappear from the Toolbox, I get warnings during build (the current project builds though), I can't see any of the forms - I get errors (please see below) - and projects that require the project with the form as an import will not build.
When I was studying what these UserControls are so that I can maybe rebuild them from scratch, I downloaded code from a book - great learning tool, but I get the same errors[code]...
I'm using Visual Basic in Visual Studio 10 Beta 2.
I did make a library with UserControls In VS2010 and I did a build. After that I want to use my UserControls from the library in a new project in VS2010.

I also set a reference to the dll file of the library, but still I don't the UserControl in the TooBox.
I am working on a project and there are about 30 controls that I need to call and update at runtime. I have named the controls day0 - day35 (it is a calendar). Basically, at runtime, I need to call each control's setDate function to display the day number. When I run it, the array just has null/empty.This is the array I am trying to use in the code behind. The controls are names day0-day35.
Private dateArr() As ucMonthDay = {day0, day1, day2, day3, day4, day5, _
day6, day7, day8, day9, _
day10, day11, day12, day13, day14, day15, day16, day17, day18, day19, _[code]....
When this gets called, I get a null pointer exception.I do not understand why the controls are not in the array?

View 8 RepliesI'm having a bit of trouble with creating one of my custom controls. What I've got is a listbox within a usercontrol, and I need to be able to click on the lists items while still in the designer. This would make it act much like the tabcontrol.

I have an application which has a tabcontrol that contains two tabpages. I have a custom made usercontrol docked to fill up each of those tabs. When I resize my main form to the minimum size allowed one tab resizes accordingly while the other seems to overflow the area and a couple ui items slip out of access/view.
One usercontrol was quite literally copied from the other and renamed and fields adjusted. The usercontrol size is the same between the two. Within the usercontrols there is a datagridview and a large panel full of textboxes and they have identical sizes and identical anchoring properties and even the same location coordinates.
I'm struggling to find a difference between the two but I really would like the resize behavior to match between the two usercontrols. I was wondering if anyone would have ideas of other things to check I did not mention here?
