We have a Windows.Forms.PropertyGrid control that we use to edit application settings. We expose the application settings through a class, giving each setting attributes to control the appearance. An example property definition is shown below:
<DisplayName("Snap Tolerance"), _
Category("Tolerances"), _
Description("The distance (in Points - 1/72"") to be searched for snap points.")> _

I have a problem with a property on a custom property of a class. Here is the actual code for the inherited form
Public Class Form : Inherits System.Windows.Forms.Form
Private _Active_Application As Custom.Classes.Active_Application = New Custom.Classes.Active_Application
<System.ComponentModel.EditorBrowsable(ComponentModel.EditorBrowsableState.Always)> _
Public Property Active_Application() As Custom.Active_Application
[code]....
but when i use a separate class to inherit the above class this property ('Active_Application', not Custom.Classes.Active_Applicaton) is disabled.
I have developed a custom DirectX UI library equipped with everything from buttons to a gridview. I need a screen-layout editor of some sort. It just takes too long to do it by hand, whether through a config file or hard-coding. I could spend a month or two developing a DirectX editing utility, but I don't have a month or two to spend on this. I could possibly justify a week.
Some requirements:
I need to be able to create a new screen I need to place controls such as buttons, textboxes, and containers/windows/etc throughout the screen I need to adjust properties of these controls (Name, Text, Width, Height, Parent Container, etc)
Some of my ideas include:Using VB.NET's form editor... setting up forms and translating the form's control information into game screens.Setting up a web-based editor (seems like this would take more than week... wouldn't it have to be flash based?)Setup a VB.NET win32 editor that allows placement of .NET buttons, containers, etc that correspond to my library's buttons, containers, etc.Is there a best way to handle this?
I have created a usercontrol in VB2008 that draws a rectangle and has the ability to apply Border3DStyles to the control.The problem I have is being able to select which sides to apply the border on during design time.If you look at the BorderSides property of the ToolStripStatusLabel you will see how it lets you select the sides to apply the border to.
View 5 RepliesIf you have a Component (or Control) with a public property of type Control, then in the Properties Window you automatically get a drop down of all the controls on the same form as the component, which is very handy. If you want to do the same thing but with an array of controls then the Properties Window shows the ellipsis and you get the Collection Editor with the Add / Remove buttons creating and deleting an instance of Control (i.e. the base class used for deriving all the others) - not quite so handy.
How do I get a list of the controls on a form and be able to select more than one? I think I need to create a custom UITypeEditor? Assuming that's right then I think I need a dialog box (like the Font dialog) with Available and Selected ListBoxes with Add / Remove buttons and appropriate code to link the control array in the component to changes in the Selected list box? Along with an appropriate UITypeEditor derived class.
Assuming that's correct, how do you get a list of the controls on a form at design time? Can I do that form design as a Windows Form, just as normal, or is it all done by hand? I've seen some code that does it with a UserControl rather than a Form, presumably that's for when you want a 'pop-up' control (like the one for Color selection)?

I have created a custom class, which contains a panel and a label on it. I added to this class a pcaption property, which holds the label text. This property is browsable and I can change its value.But when I drag the custom control to the form and change the pcaption property, it has no effect. Even the <Defaultvalue> has no effect. Why?

I have two forms, say Form1, Form2
Form1 has one textbox and one button, Btn1 when clicked, it opens Form2 as dialog.
Form2 has one textbox and one button too.
First I click on Btn1 to open Form2 as dialog. And when I click on Btn2 on Form2, I want the text in the Textbox2 to be copied to TextBox1. I know it could be done by Public Property Get, Set but I am stuck.

I'm trying to add validation to one of my class properties:[code]The value for the golfer's handicap comes from a oombo box on the form. Even if I have nothing set for this property at runtime, my validation doesn't work. I tried putting the If statement under Get instead of Set, and tried mHandicap = value after an Else in the If statement, but nothing seems to work. I'm working in the dark here and can't find anything suitable online. I was hoping to not go down the path of ReadOnly or WriteOnly properties as I'm not at that stage yet, but does this make a difference for my purposes here? Can anyone guide me as to what I'd need to do from this point? If I've got it right, you can add validation in the class and this means that you then don't need to repeat this validation in the form??

I'm trying use just a user control form to act like the old VB6 picturebox. Mainly, i'm doing this is because a user control form is also a container but i also want it to have an image property. I've done this. The new control does have an Image property but the problem is that the user control form doesn't have an image property but only a BackgroundImage property.I was hoping that there is some way to place the selected image, directly on the surface of the user control and not to it's BackgroundImage property. Here is what is got so far:
Code:
Public Property Image As System.Drawing.Image
Get
Return Me.BackgroundImage
End Get
[code]....
As you can see, for now, i have to use the BackgroundImage property but i want to image to be placed on the controls surface, so that the image can be manipulated, like drawing game tiles on it or image processing. The user control doesn't have a real image property?
I have a For Each block loops through a list of objects, the objects are all instances of a single custom class I have made which has multiple properties.The logic used in this block uses a property of the custom class to do a set action, is it possible to dynamically supply which property it uses in the logic? This will be more efficient and prevent me from having to create this logic over for each property of the custom class.My best guess was that maybe it is possible with reflection, however my searches into reflection have left me more confused.
