I am trying to learn how to create Windows Forms custom controls in VB.Net by creating a .Net version of an old control I created in VB6. On this control, I have a UserControl with a Label (lblCaption), and several of the properties I add to the control should be passed to the label.This is the code I tried for the ForeColor property:
Code:
Protected mcolForeColor As Color = Color.FromKnownColor(KnownColor.ButtonHighlight)
Public Overrides Property ForeColor() As Color
Get
[code]....
When I change the ForeColor on the control in my test project, lblCaption does change to the color I selected; however, when I run the application, the label changes back to the default (button highlight) color, and the value of the property is also reverted back when I return to the form designer.What would be the proper way to implement the ForeColor property on a custom control?
I need to work with custom controls, I want to be able to set the properties of my controls so when I put them on my windows forms they will show up in the properties window thing.
What I've done is create a User Control Library (Project) and I've added a single User Control to that project. The control contains a single FlowLayoutPanel, and I created a Property on the control itself to pass the FlowDirection from the Control to its FlowLayoutPanel child.
Build, reference, component appears in the Toolbox and everything works fine, but the property on the control does not appear in the Properties window when I go to edit it at design time.
I've populated a PropertyGrid with a custom class. How do you create and display a sub property similar to Size (Height, Width) which has two values or Point(X,Y)? For example, the class is Test and the property is Item as string. I want to expand Item to have two sub properties, A and B.
The object browser in visual studio contains many controls and properties ....so is it possible to remember in mind all these controls. Whenever i am programming in vb 2008 and for reference i look at the examples on internet i always find some new controls,properties etc which makes me confuse.So i was wondering If by any means there is a way to remember all these controls
How can I add controls to a form in code and set the properties of the controls using the With statement?Also I would like to know how to add a container control and then add a control to that container.
I need to implement some (maybe 10) custom properties for logged in users for my MVC3 vb.net web app. These will define how certain data is displayed within my views. I can think of a couple of possible solutions..
I was thinking to put attributes on BLL classes properties which ever are mandatory and I'm successfully able to retrieve the attributes also. But, not I also want to check the value of propeties. How I can do that:[code..]
I created a custom datagridview column for a progressbar and included customizable color properties but I can't get them to work right. After compiling, the properties show up correctly in the Edit Columns popup editor, but changing the values has no effectThe designer generated code shows the original values and manually changing them there has the desired effect(I know you're not supposed to, just testing). Here is the code for the column even though I don't think the issue is stemming from any coding errors there.
I'd like to add some custom properties to the columns of my DataGridView control. I'm not sure how to do it.I tried this once before but never got it finished. Basically, I'm making a teacher gradebook. Fore each column, I need to add properties called Assignment,DateAssigned, DateDue, PerfectScore, AssignmentType, etc.
In our IDE, for example, Visual Studio, if we display the properties of a System.Windows.Forms.Button control, we see some properties that expose anoter set of properties. For example: FlatAppearance, Font, Location, Margin, etcetera.I would like to do something similar in a custom control.I know the code behind is wrong, but here is an example of what I´m trying to do:
Public Class StateOfMyCustomControl Public Enum EnumVisibility Visible
[code]....
In my IDE, in the properties window of my custom control, I would like to see my property State, with the possibility of display it to set the properties Visibility and EventManagement.
I have developed a Windows service application in VB.NET.My need is to have custom property tab like "General", "Log On", "Recovery", and "Dependencies". Because I need to configure my service and also want to display some extra information in that extra tab.
I'm moving my first steps in the VB.NET world (I come from VB6) and I'm stuck with the creation of a particular class.
Let's say we have a bus that always has 101 places. I'm trying to create a class containing the map of the bus, along with methods to graphically represent it.
My "Bus" class will have a couple of properties ("BusColor", "BusModel") related to the whole bus. Then it should have a property called "Places" whose type is a custom class thet represents every single place, along with, for example, the passenger name or the place number. This property should of course be an array.
This is my code so far (simplified):
Public Class BusMap Private Const MAX_PLACES As Integer = 101 Private _BusModel As String = ""
[Code]....
but I wonder if there is a more standard way of doing this.
My second question is: how can I modify my class to be able to iterate its Places property with the "for each" statement? A quick search on the web showed up that I should implement the IEnumerable interface, but I'm still not enough confident with the concept of Interfaces.
Lets say i'm making a new dialog. I don't want to expose the properties of the form to code elsewhere, only specific ones I define. I tried making the form Protected (including the Designer generated code) and putting it in another class, but then I can't figure out how to access the form from my code. Am I going about this completely the wrong way, or what?
Is it possible to iterate through the properties and methods of a custom class, getting the details about those properties and methods in the process.[code]....
I have built a Custom Control Class that makes it much easier to build a side bar element in my html.
The problem I am running into is that when I set the "Text" property, the last time I set it gets used for every instance of the control on my page. This is my first time doing this, so I'm assuming I'm missing something basic.
Is it possible to make a form that can set the properties on a custom control in the designer? What I mean is I want to know if it is possible to show a dialog that allows you to set the settings for a certain property like if you were adding items to a listbox.
I'm working on a project where I need to information on all the monitors connected to a computer and then write a configuration file based on that. I can already get the screen information by creating a new instance of screen and reading the information such as index, bounds and everything else.I'm trying to create a virtual screen object to hold the information from the screen so I can work with it, or add other properties to it.[code]This all works perfectly how I want it to. Except I would like to do one more thing. How can I make it so that instead of getting Virtual_Screen.Top, I could get Virtual_Screen.Bounds.Top? That way I could create other properties such as Virtual_Screen.Border.Top..I have no idea how to code, or what that would be called. It's hard to search for something you don't know the name of.
is there any way that i can set the property of a control all at once? like for every button, i want their backcolor to be red. something like that.also is it advisable to set the properties of a control in design view rather than code it? does it have any performance issues?
I have 53 text boxes in my windows forms application. I need to save the "text" of all the textboxes into a single file. Is there a way, I can control all the textboxes as a single textbox group and use its properties.
For example: Can I write something like : For i As Integer = 0 to 52 Textboxgroup.text = TextBox(i).Text Next ??
I recently uninstalled an IDE for a motion control system (Delta Tau) that is a visual studio based product. Now when I bring up my Visual Basic 2008 IDE that I'm using to write an HMI for the control system, the properties for controls placed on forms doesn't appear in the properties window. And if I click on properties for a form I get the FileProperties2 information, not the form control properties such as size, location, or color. I am also not able to access the controls in the VB toolbox to place on a form. The controls are grayed out and unavailable. what part of Visual Studio 2008 got broke in the Delta Tau uninstall?
I'm trying to write a routine which will produce a list of the values of some of the properties for every control that I've placed on a form. I can do this manually by looking up the names of each of the controls, but I'd rather use a construct like this -for each formname as string in xxxx
for each ctrlname as string in yyyy(formname) .... next
next
However, I'm having problems with the various examples of this code that I found in the library. I'm not sure whether it's because I don't know how to set up the syntax correctly or this sort of construct isn't possible in this context.
This is similar to my last post but with a different purpose.I have built a custom control, but when I set the properties for it... ALL instances of that control on my page grab the exact same property. I need to be able to set the property to "abc" for one instance of the control on my page, and then set the exact same proprty to "xyz" for a different instance of the control on the same page.
I have a custom list control, using labels to display content.How can I add a list property to the control so I can inject items into the custom listbox?I know how to make properties for strings etc. but I can't get it to work to make a list property...
How do I get at and invoke the properties dialog supplied by the manufactured? I have search this many times and found that most of the posts contain solutions that the original poster claims don't work The standard PrintProperties class does not handle a lot of printers who have specifictsks, eg a printer designed to pint on the face odf CD/DVD. I have found examples of how do this in VB6, but every examply I find for the versions of VB Basic after thet have comments that the solution provided did not persist the user chnges. Bow, come on, there has to be a way of displaying and persisting the user choises the dialog bog provided by the printer manufacturer!Terry
