Dec 6, 2011
I have a form named VBProject It has two TextBoxes and one custom control named MyControl which is created in another project.MyControl's project has a form inside, named Form3. When My control is loaded it needs to find all controls in my VBProject and add them into a listbox which is in Form3. Then Show the Form3. In the end ListView need to shows name and text of textboxes but it shows nothing. Here are my codes:
MyControl's Load_Event:
Dim i As Integer = 0
MessageBox.Show("Control Count:" + Me.Controls.Count.ToString)
For Each MyObject In Me.Controls
If TypeOf MyObject Is TextBox Then

Is it possible to have a custom control (inherits from Control) and add sub-controls to it (like, a label for example)? Basically I want a composite control. I know controls can contain other controls, but if I try to add a control to MyBase.Controls, this doesn't work because that's readonly.

[Code] I have a panel as the base of my custom control and I am adding other panels to it, along with a flow layout panel(myInnerContainer). I know the code above isn't going to work because when I try to add the regular panels to the main control, they will attempt to be added to the flow layout panel myInnerContainer, and cause a circular error. [Code] but intellisense doesn't display anything which leads me in the correct direction for adding only the buttons to the flow layout panel (myInnerContainer).

I have created a customised checkbox control (only the text and border appearance has been modified), and wanted to loop through them in a User quizto see which have been checked and are correct. I have used the Tag property (set to 1 or 0) to identify incorrect answers, and tried to loop through with the following code:For Each thing As GMAW.MyCheckBox In currentParent.ActiveMdiChild.Controls

At the moment, I'm writing tons of custom control, which all fits my needs. But the thing is, each time I Debug the project, it doesn't update the form designer at all, not even the code. My solution to this is to Rebuild the project, which can take time. This is very frustrating.
I'm using Microsoft Visual Studio 2010 Ultimate to compile.

I have a couple user controls that are loaded by a Select Case statement. However, in the behind code file for the main page that loads these controls, none of the asp controls show up in intellisense. I had a feeling it's because the controls are loaded conditionally. My question is what is the best way to solve this?
1) Load the controls and do a Select Case in the behind code to make them hidden or not.
2) Is there a way to say (psuedocode): LoadUserControl("UserControl1").Controls("tbTest").Text = ""
3) How can I pass a dataset to the User Control file?
4) Any other ideas?[code]

I want a list of all controlls in my project, not only on open forms. The reason is that i want to make an access control, and the admin will set which buttons each users can use.
What ive got so far is:
HTML
Public Sub getallforms(ByVal sender As Object)
Dim Forms As New List(Of Form)()
Dim formType As Type = Type.GetType("System.Windows.Forms.Form")
[CODE]...
This shows me all forms in project. But i cant access their controls.

After taking a few years off from programming, I decided to start learning vb.net. I have created a user control that contains a picture box. I added some custom properties to the picture box that will hold general string data from a database.
My problem is that the user control is programatically created during run time, and during this time a DoubleClick event handler is added for the picture box that is within the user control.
I need to be able to set the custom properties for the picture box during the creation of the user control, so that when the control (picture box) is double clicked I can read these values but am unsure on how to access them.
The picture box is the entire size of the user control, or I would just add the custom properties right to the user control and add the DoubleClick event handler to that. However, double clicking needs to be done on the picture box since it takes up the entire user control, unless anyone has an idea to trigger the DoubleClick event of the user control when the picture box is double clicked.

I have created a usercontrol that contains two rectangle shapes to create a unique button effect and a rounded-corner rectangle shape serving as a border to provide a look similar to a group box. It also contains two labels, one for use with a Text property of the control and the other to indicate the status of expansion of the control. The control is designed to collapse itself when the "button" is clicked leaving only the "button" visible. Clicking it again toggles this affect. I've dubbed it an ExpansionBar. It is also designed to be a container control so that I can add controls to it and allow these to disappear when the bottom portion collapses. The problem is that the controls contained in this usercontrol cannot be accessed during runtime. In other words, I can add a checkbox to it and it will disappear correctly when the control collapses, but I can't select the checkbox to check it... same thing with any other controls, you can see, but can't touch. I'm a novice developer, so I'm sure I'm missing something obvious.

This relates to WPF but is broad enough that a winform answer will do. I have made a few custom controls in the past by inheriting from whatever particular control I wish to inherent from.
I have noticed that I can add a form to a class/user control library from the add new dialog and have it run. When this application is compiled I get a DLL.
So my question is can I use a Form as a custom control. The reason I ask is I am creating a more advanced MsgBox for a new application I require and a form as its container makes the most sense.

How do I do something like this.[code]...
This is inside the Module separate from Form1 class as you can see right off the bat it's not a class and there is no reference to Form1.. how do I access Form1 without passing reference to make factory modules work like this.

I have a form called form1 which has a thread that runs a sub from a module.[code]...
Well from the module, there's a part where I have to update controls on the form1. Whenever I try doing it, it updates the value, but not the design. For example I write a delegate which makes label1.text = "111", while debugging, label1.text becomes 111, but it does not show it updated on the form design, it just stays at its default value.

I have created a custom control that is included in a control library that is referenced by a VB Forms application.
When I modify the control, and have the application open in a VS window, VS usually asks me if I want to reload items that have changed.
However, a couple of times, it has not asked me this, and when I go to open the form that contains the modified control, I get an error window warning me that if I ignore the error message and continue, then I risk making VS unstable. I've learned to ignore this error message, continue, and immediately save the form to a new file.

I am trying to access the controls' properties on another form without having to modify the code of the other projec (the one containing the controls that I want to access) because it is already compiled as a DLL. In this DLL that I am trying to access, the functions/sub-procedures are all declared as private. Would there be any way of accessing the controls' properties without having to modify the DLL? Basically what I am trying to do is create a sort of console application wrapper for the DLL that would create a new instance of the DLL's form and then make certain checkboxes checked and click certain buttons. Basically, I am trying to automate the form as it currently exists.

If I drag another Form/Program or maybe lets say a context menu happens to open over my custom Control, this happens.It does correct itself after causing a redraw, however it's quite annoying. Is there anyway to avoid this?

I'm trying to create my own control to build a custom planning on it.After trying it with loose controls I got an error but after advice on my previous post, I redraw everything.I have now the header of the control finished, the header shows the days of the month for as many months that fit in the window.Now I want to put the list of data below it, but it will be more than the windows height, so I need to have a scroll bar that will scroll the data but not the header.I would not like to design my own scrollbar and rather use the scrollbar control for it, but when I put it in, I cannot use the NEW keyword.example:
Dim sb
As
ScrollBar
with this I get the error message: 'New' cannot be used on a class that is declared 'MustInherit'.How can I get a scrollbar on my form to scroll the list only (so not the header)?

I'm coming over from VB6 in which you could use 'user controls' to create reusuable custom controls. They were simple and contained and you can easily create several instances of a user control within the same or other apps. In vb2008 there are user controls but I can not figure out how to add them to forms or or other apps. Can someone please give me the the basic steps to add a custom user control to a form or project.

Having some issues with creating a simple control in vb.net.
I create a control with a single label in, I don't change anything except the colour of the control and the label and also making the label anchor to the edges ( with a small border around the edge)
When i then build it and add this control to a form. Some of the edges are cut off and it isn't anchored the way it was in the control.[url]...
as you can see in the second image the control has lost its white border at the right and bottom.

I created a custom control and add it to a form programatically.
The user can add and move them all over the form.
The problem is when I want to clear the form of my user control I don't know how.
I created an array of my control called ctlCorkNotes
Say I create ctlCorkNotes(1) and now I want to delete it.
How do I do this so it is gone and would have to recreate it to show up again?
