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.
I'm trying to create an IE addon that allows me to just switch proxy settings. I'm sure there is something like this already, but for me it's an exercise in programming and learning as well.
When i push the button,code create me a new form but i don't know where is it?I want do something with this form take on it any controls or something like that but i don't know how activate this new form?Where is this new form?
I 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.
on vista trying to create a reference to a registered DLL which succeeds with VS2008 but not with VS2010 (get system cannot find the reference specified).on vista and win7 using dependency walker the DLL cannot find IESHIMS.DLL which is in the IE folder.
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
This is a followup to this thread, where I'm trying to draw two sets of dots using HatchBrushes to create VS2010-like interface. If you take a look at the zoomed image of the IDE background (blue with dark and light blue dots): that is what I'm trying to draw using GDI+. In the previous thread ForumAccount find the correct HashStyle to use (Percent20), but there is a problem: I need to draw two sets of these hatchstyles: once with a slightly darker color and once with a slightly lighter color, at an offset of one pixel downwards.
Well, 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 MainLayout.master that has UC_Menu.ascx on it. I have a page named Customer.aspx that uses MainLayout.master. Customer.aspx also contains a UserControl named UC_Details.ascx.How can I have UC_Menu.ascx call a function that is in UC_Details.ascx with this scenario?
I have a Windows Form frmMain() holding seven more-or-less unrelated UserControls, ucFlopsy", "ucMopsy", "ucCottontail", etc...I say "more-or-less" because each of the seven UC has three similar public read/write properties:
IsLocked (a boolean indicating if the following two properties are "Locked") IsLockedID (if IsLocked=True then IsLockedID is an integer) IsLockedName (if IsLocked=True then IsLockedName is a string)
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) Get Return DBItems
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.
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.
I have a program in VB.NET that has a webbrowser contorl. I wanted to zoom on a page and i found a tutorial online that involved something like thiswebbrowser1.ActiveXInstance.ExecWB(OLECMD...When i went on and typed it on, there's nothing called ExecWB.Why is that? Is it because i'm using IE9?
I have been testing and experimenting with "one click publishing" for a week now, and still cannot get a successful deployment. The results i get are listed below

I am working on a login page for an asp.net application. I'm making my own login and everything is working so far: I get a connection, the query is asking to return Count from the table where the username and password match the username password in the table.
I was wondering if they was anyway to get webparts working in other browsers except IE if not is they any other free alternative that has the same drag and snap and saving capabilities?
i'm doing the project of database by using IBM-DB2 and i need to use the visual studio 2010 to connect with IBM-DB2 and i have saw the comment that posy by someone. I follow all the code there and now i found some have a blue line.
Imports System.Data.OleDb Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 'connection string
Just in case, I missed anything. As far as the google result, I don't see a capability to develop iPhone app using VS2010 (sorry, maybe I shouldn't ask this question here). right? Or, is there a way to write the code in VS, and then using some sort of converter...
I know that there are millions of posts about this already but I cant seem to find one that mirrors my issue. I am using VS2010 and want to automate excel and I'm trying to work through the example here.
MS Tutorial The problem is when I go to add the reference as mentioned 3.Add a reference to the Microsoft Excel Object Library. To do this, follow these steps: -On the Project menu, click Add Reference. -On the COM tab, locate Microsoft Excel Object Library, and click Select.There is no such reference available.
know if this is the right way to automate excel with VS2010.If it is could someone please let me know why I dont have the COM option for excel. im wanting to write in VB.net but if someone has an example in C# that would be fine. I have tried implementing automation using the Microsoft.Office.Interop.Excel.Application dll but i get the following exception when I try to create the excel application.
This line generates the error. EXL = New Microsoft.Office.Interop.Excel.Application()This is the exception
Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))
