I just created a "Usercontrol" in WINFORMS- it just contains 1-Button with some style.And i need to use the same as array(10) and load it to a form.
Ex:Dim myButton() As Button = New ucSpecialButton(dataset4Category(i).Tables(0).Rows.Count - 1) {}
Here my usercontrol name is ucSpecialButton can we create a ONE-Dimensional Array of a WINFORM usercontrol.?
I/we (my class) created a usercontrol that included a picturebox and a timer. We declared the public variable to access the timer enabled property. Placing the user control onto a Form we are able to enable the timer. However, when we went to declare an array for the control we could not access the properties... We successfully declared control arrays using base class control...
View 11 RepliesI am interested on creating a parent control like the kind of TabControl, and it may contain some pages like TabPage.How can I create a parent UserControl class and how to add pages to the parent control?I think the control could be clicked in the designer when you are switching to different pages like clicking on the tabs in design mode. I may need to create a parent class and a extended panel class to add in the parent container.
example: In the designer, when user click on the title of the panel, it will expand the panel for designing.
I am trying to create a UserControl in VB.net, under VS2010. I have the code for the UserControl and I would like to add it to a form. My problem is that, according to every book and forum I have seen, after I build the UserControl, it should show up in the Toolbox. It doesn't. I even downloaded code from a book, the code executes perfectly, but their TrafficLight control doesn't go in the Toolbox (even though the book says it should - and that the only way to set its properties and to add it to the form is through the Control properties). I have tried to add the control to the form manually, by declaring it
Dim myObj As New SomeClass.SomeControl
and in the Designer.vb, identical with the buttons on the form:
Friend WithEvents myObj As SomeClass.SomeControl
With both, I get an error saying
'myObj' is already declared as 'Friend WithEvents myObj As SomeControl' in this class.
And either way, I get an error when I try to look at the design:
Could not find type 'SomeClass.SomeControl'. make sure that the assembly that contains this type is referenced. If this type is part of your development project, make sure the project has been successfully built using settings for your current platform or AnyCPU.
The control by itself builds and shows up in design view (not in the Toolbox though, even though it Imports System.ComponentModel and Inherits System.Windows.Forms.UserControl and... what else ? I tried to build it in a separate project, to see if I creating a separate dll will make a difference, though I really want it in the same project.
defauld the usercontrol create(when is used) the backgroundimage property, but these property can be blocked? i'm asking these, because i need the entire control in that property

View 9 RepliesWell, the title pretty much says it all. I have a user control that is a a collection of six label controls. three are used as visual color indicators, and the other three are used as the corresponding value for each color indicator. (It's sort of like a legend key on a chart or map.) I have created a custom class to store the three values, and the associated methods to interact with the values. (I can probably use a structure instead of a class, but right now, I don't want to discuss that.) My problem, is that I want to show my user control inside a cell of a DataGridView. I've looked at the examples that create a MaskedTextBox DataGridViewCell, but I can't seem to get it to work. Here is what I have:

I have a Windows Form that contains a custom control container as a UserControl. For the sake of this question, this custom control container is called Dashboard. This container called Dashboard contains numerous other controls depending on their permissions. I need to raise events that are contained on these controls through the Dashboard control and over to the Windows Form.
How can I bubble up the event? I'm using VB.NET for this project, but can convert C# into VB.NET.Also, to complicate matters, the main Windows Form is a VB6 project. So, I'm using the InteropFormsToolkit to accomplish this.
I have two UserControls on a MasterPage. DataEntryUC contains several TextBoxes and DropDownList. NavSaveUC contains navigation buttons. When the user clicks on a navigation button, I will be saving the data entered into DataEntryUC from the NavSaveUC UserControl.
I have a couple of tables in my DB that contain stored procedure names, control names, control types, SqlDbTypes, etc.... that correlate with DataEntryUC.
How do I reference a text box that is on DataEntryUC from NavSaveUC?
I have been working on the following code from NavSaveUC with no luck.
Dim MyControlName = "txtFirstName"
Dim MyControlType = "TextBox"
Dim MyStringValue as String

I have a usercontrol that has a main form and calls another form within the usercontrol to get some data from a database that allows the user to select some items from a CheckedListBox control on the sub form. I want to pass the selected items from the CheckedListBox back to the main form and display the results there. I have a public property called DBList of type List(of String) on the main user control. If I create a reference to the usercontrol form the second form within the usercontrol I get a new instance of a user control. All I want to do is set the property on the usercontrol and close the secondary form. How do I reference the usercontrol from the form within the usercontrol?
Code in UserControl:
Public Property DBItems() As List(Of String)

I have a usercontrol that has a popup that displays another usercontrol when the user selects an item from a listbox. When the parent initializes, all the usercontrols initialize.

and it just keeps the original data in there. I'd really like to just reinitalize it every time and basically have a new webpart each time.
This was an experiment to see if I could create a fake array using generics instead of using an array. I decided to try it, because I may use it if I find any advantages to using it over an array. it works, I am just asking for a second or third opinion, have I screwed anything up, or is there an easier way to accomplish this? If I use it, it will be for a 2D game I am creating, and is used to draw the 2D screen graphics, placing an image based on what image identifier is located at what coordinates. The value stored in the fake array is an integer that disignates the graphic to draw and whether it is passible or not, i.e. 0 = a floor image, 501 = a wall image that is impassible (any image number > 500 is impassable) The Class definition:

I just discovered the joys of UserControl's and I was wondering if it is possible to populate the usercontrol with data from a database in the UserControl's Form.Load event instead of the form the userControl is placed on. I feel it would make using the control a lot easier if it just populated itself without anymore code.I tried it with a ListView but it gave me a bunch of errors, so I didn't know if it had to be done a certain way or if it was just one of those things that doesn't work no matter what.
View 8 RepliesI want to create an array of an array (or arraylist of an arraylist) to hold strings.I want to fill an array1 with string values Then add this array to array2. - but only taking up 1 row in array2 e.g something like array2(index)=array1 Then clear array1 then loop through this again with different data, and add it to the array2.so will end up with something like
array2(0)... contains a collection of array1 data
array2(1)... contains a collection of different array1 data

I'm writing a ray tracing program that uses snell's law to trace rays through a system of lenses to examine abberations in a given design.I have a class called lens, which holds variables for example, name of the lens, description, number of elements.I want to be able to have a sub class or array within lens (or some other way to manage this data).I wont know what number of elements is until run time.
So I would need to define the array at run time.Part of the idea of my program is randomly generate lens elements within given rules (as in a massive lot), keep the top designs and continually refine them by making billions of micro adjustments to the variables that define the lens etc, which I can pick up later on as it'll save the database/variables.For example, say Lens(63).NumberOfElements = 6.
I want to be able to access Lens(63).Element(3).Radius1 Etc, there will be a bunch of variables under Element, such as Radius1, Radius2, refractive index, horizontal diameter, vertical diameter, and spacing between the next element if it isnt the first.
And Lens(70) may only have 4 elements etc. How can I define a different array size like that in the class under different parent array indexes at run time?
