how to find the form that a component resides on.
I googled this and found several articles stating to do it as follows:
vb
Public ReadOnly Property FindForm() As ContainerControl
Get
Return mc_FindForm

I am converting an old Vb6 solution to .net 2.0 in vs2010. I've been working in C# for about 3 years now and .net for 5. I don't recall having this problem in C#, but if I want initialize a readonly collection of DerivedControlFoo Is there a clean way to do it besides creating a sub to do it all off somewhere else? I'd love to be able to do it at the class level at the declaration for readability and simplicity.
View 1 RepliesI have just downloaded and installed both MS Report Viewer Redistributable 2005&2008 but I could not find it in the .net framework component. I am using Visual Basic 2008 Express Edition, does it mean the express Edition does not support such component?
View 1 RepliesI retired recently from a job where we had VS2010 Professional for doing ourdevelopment. Now that I'm retired I can't afford "Pro" and cannot find the component than looks like this (see above). Is/was that component left out of the "Express" version? Do I have to "load" it (and, if so, what name should I look for)? I vaguely remember it being some kind of container for other components.As a follow-up question - can anyone provide a (readable) example of creating a two dimension array of this item I could study?

View 13 RepliesI have 2 forms main_frm and copying_frm. In main_frm, there is a list view that is populated with file names. The user then clicks save and all the files in the list are copied to a folder that they choose using a folder browser dialog. When this happens, I do copying_frm.ShowDialog() to display the copying_frm. The copying_frm contains a progress bar and a cancel button. I can get the progress bar to indicate how much has been copied. But that freezes up the application. To get around this, I create a new thread (called copyingThread) that copies the files. When that thread runs though, it can't access the waitingList_lvw in main_frm. For example, in the function that the copyingThread executes, if I have this line of code: MsgBox(main_frm.waitingList_lvw.Items.Count.ToString()) the result is 0. Also, I don't get any errors and no files are copied. How do I access waitingList_lvw in main_frm from a thread called copyThread that was created in copying_frm?

View 1 RepliesI'm trying to make a Toolbox component which the user can drag onto a form in the VS Designer. The component has to recognize the Form it is on, in order to handle certain Form events. I would prefer to do it without requiring the user to add any code to the form. Does anyone know a way the component can get the identity of the form?
View 4 RepliesI have developed a Component and I want it to be able to detect when it's running in the IDE.
Or, let me rephrase that - I want my component to be able to detect when its parent form is running in the IDE.
I can use .DesignMode and a few other methods to detect when my component is running in the IDE (For example when my component is placed on a form etc)
But when the parent form is executed from within the IDE then .DesignMode returns false.
Is it possible for a component to detect if its parent (the form) was started via an IDE/Designer ? or via the command line/start menu or what ?
after i run the program, the form pop up showing no problem.however, when i click on the maximize button on the top right of the form, the form enlarge and fill the screen. but the components will not move accordingly.
View 2 RepliesI have an error that keeps regenerating when the form is closed and open back up.
1) Windows Form Application (Project: TestProject)
2) Add class in same project:
Public Class Test : Inherits System.Windows.Forms.TextBox
3) Drag and drop into the form within the project (works fine)
4) Close form
5) Re-open form... then error about the class Test in the project not defined
Actual Error: Type 'TestProject.Test' is not defined.
Is there a best way around this besides creating a separate project and putting the 'Test' class in that separate project and referring that separate project in the 'TestProject'?
Modified Added: By the way... i've used Global.TestProject.Test... but then again another error generate with the custom property within the 'Test' class.
Commonly if I maximized my form. It'll look like this And now, i just want to ask a simple question.. How to centered all those components if i maximized it??
View 1 RepliesI'm having problems with coding in VB 2010 Express. One of the many errors I am dealing with is the user interface form. It says it's a component, so I have to use it in a form.
View 2 RepliesI recently have been developing an application in .net that uses lots of components created as digital/analog input/outputs, and, when each component is clicked shows a form that shows it's state.The problem is that the form allows to change the state of the component and I don't really know how to reflect the change made in the windows to the component variables, as I don't know if there is a way to call the parent from a windows form or any similar way to do it.
View 5 Replies(I use VB 2008) I'm working with the webbrowser-component. I got a problem to fill a text-field. The textfield is named "description" but I cant fill it. I guess it's because it's more than one form on the page that got a element named "description".

I've created a component whose name I'd like to be able to change while editing in the component tray. I've added a Designer action for a name property, but now I'm stuck.
Looking at the property grid, I can see that the name property is parenthesised, indicating that it's not a regular property.
Im learning Tcp communication right now, and Im a newbie :P First can i add a component to the form for tcpclient and tcpserver like a add one for a textbox and a botton?
Second, which method is better Dim listener As Net.Sockets.TcpListener Dim listenThread As Threading.Thread
or Dim tcpClient As New System.Net.Sockets.TcpClient()
So I have decided to learn more about this Invalidate() thing. I decided to simply draw a rectangle where the mouse clicks in the form, for testing.
Code:
Public Class Form1
Dim p As Point

I have a component which hooks up with the paint event of assigned control and draws on its surface, Whenever i make any changes to the component i need to resize the form or control at design time in order to see the changes.
I want to ask if there is any other way to refresh the contents of a control at design time which forces it to redraw.
