I'm trying to add a custom panel to my toolbox using a dll file, but when I add it as a reference it only appears as greyed out - and this is only after I click "Show All" in the toolbox.Everything builds fine in the Class Library project I used to create the custom control. Here is the simple
Imports System.Windows.Forms
Public Class pnDoubleBuffered
Inherits Windows.Forms.Panel
Public Sub New()
[code]....
I build the project, open my main project where I want to use the control. Then I click "Choose All" from the toolbox and add the reference using ".NET Frameworks Components". I find my dll file and click OK. Then nothing is added to the toolbox. I manage to see the control greyed out when I click the "Show All" option.
how to specify a custom icon for display in the toolbox window when you create your own custom control? Something other than the dreaded "gearbox" icon.
View 2 RepliesI have created 2 WPF control which reside in the same folder and i want to add one control to the other.
The controls are added in a Win Forms project.
the thing is that in a custom Win Forms control I can see my two WPF controls in the toolbox but in the WPF designer I cannot see any WPF controls.[code]...
I made a custom control that is a 15x15 grid designed to show a tiled map. Inside I have a class that inherits from pictureBox. The problem comes when I try to place my DLL inside the toolbox. When I click "browse" and select my DLL to import it simply import my class inheriting pictureBox instead of the whole package.
Here is a picture of my files. Grid.vb is the control, clsTile is the pictureBox class and the other one is irrelevant. [URL]
I made a customized TextBox that I'd like to permanently add to the toolbox. But when I close the project that I created it in, my new control also disappears and I have to copy/paste or import the class-code every time I want to use it. Is there a way to get the control in the toolbox "forever"?I tried to enclose the class in a "Namespace CustomClasses" statement and changed the root namespace in the project properties to "CustomClasses", but nothing of what I tried is permanent. I prefer to store my classes in a "real" root namespace, in the same root as the microsoft and system namespaces.
View 4 RepliesI have a solution with about 5 projects, the main (startup) project is a windows forms project while the others are control libraries that contain some custom controls. The main winforms project however also contains some custom controls.
Recently, the controls in the main winforms project have stopped appearing in my toolbox. The controls from the other control library projects appear just fine, but none of the controls in my main project will show...
Some of the projects are VB, some are C#.
I have tried everything I know to fix it:Delete bin/debug folders and restart
Build, build, build, build, and build Target the same .NET Framework version and CPU platform in all projects Build again Nothing works...
All projects target .NET Framework 4.0 and compile for the x86 platform (since I am using Access db). All projects build successfully, no errors. I can run the solution just fine. I can even declare and add the controls in code and they work just fine. They just don't show up in the toolbox so I can't drag them to my form and I have to dig into the designer code everytime, which is really annoying!
What I would like to do now is well convert this somehow to a class. so I do not have to DirectCast the items. Is this possible?
Here is the original code that kleinma assisted me with:
Dim CtlLosArray(150) As ShieldLOSInfobox
CtlLosArray(0) = New ShieldLOSInfobox
CtlLosArray(0).Location = New Point(0, 0)

Is there a way to make this into a custom class so that I can make things easier to manipulate? at least that is how I think it would be done.
If we say blue is the default colour of the Backcolor property I understand it as if you don't specify a colour for Backcolor blue will be its colour. But I could not make sense of default property of a class in the context of building a custom user control. After calling an instance of a class we have to either call one of its members or assign an other object for it. Therefore why should there be a default property?
View 9 RepliesIs it possible to create a user control with a list of custom class type property? If it is, how can I? The issue is that, in designer mode the property is not displayed in property window. I can add the list on markup but when i switch to the designer mode it gives an error which is 'The user control does not have a public property named BookList'.

I created some custom controls which I use quite often and I thought if I add them once to my ToolBox they just will be there next time I start up VS2008; however, that does not seem to be the case! Each time I start VS2008 I have to re-add that controls (which is quite annoying!). Is there a trick / way of having them there permanently?
View 6 RepliesI am working on a project which lets the user edit the students in a certain group using a datagrid. First I created a class called student and then I created a student-array. Displaying the students in a datagrid works fine. On form-load, I change the datagridview.datasource to the student-array. The datagrid has 20 rows by default (Public dbstudebt(0 To 19) As student). When I edit an existing student everything works fine but when I fill something in in an empty cell and press enter or tab to confirm and add a new student, it just clears the cell and nothing happens. So basically, editing existing studs in the datagrid works fine, making new student doesn't work at all as those cells are always cleared immediately.

I am trying to add a dll that contains some custom 3rd party conrtols and some in house user controls and am getting the following error -

How do I inherit an existing control (user control) and add it to the ToolBox?
View 2 RepliesI can't seem to figure this out. I basically am trying to write a class, not a usercontrol, that can show up in the ToolBox. I want it to act similar to how a ContextMenuStrip or BindingSource does, in that there is no UI when you throw in on the Form, it goes down to that bottom part (name?).
1) What do you call those types of components?
2) Why won't this test class that I wrote do the same thing?
vb.net Imports System.Windows.Forms
Imports System.Runtime.InteropServices
<ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch), ComVisibleAttribute(True), _
System.ComponentModel.ToolboxItemAttribute(True), System.ComponentModel.DesignTimeVisible(True)> _
Public Class FilterMenuStrip

If I try to add it to the ToolBox, I get a "There are no components in '<The DLL>' that can be placed on the toolbox."
I was asked to create an application that has a custom control that acts as a button. I managed to do almost all the requirements except the one for the KeyPress event. The customer wants to click the "Alt + C (for example)" to trigger the button click event in this case for a Cancel button. I did the code and it works fine ONLY when that custom control has the focus on it. But when it loses it, it doesn't. I don't know how to make the form accepts that KeyPress and sends to the custom control. I tried to set the form's KeyPreview property of the form to Ture but it didn't work too.
By the way, I know that it would work by writing the code in the KeyPress of the form but that's not the requirement because the user control will be used as a standalone component for many projects.
I'm developing custom .net themes, and this relies on GDI+ -- I've been able to do this mainly with a ThemeBase released on another website. Now, however, whilst inheriting another control, I am Unable to inherit the ThemeBase which means I have to design the control a little differently -- which relies on me being able to manipulate the 'OnPaint' event of the control's design.The control's 'OnPaint' event is never fired, and I don't know why. Here's the entire textbox code.[code]

View 5 RepliesI figured it out. Check out the finished control [URL]..I'm trying to make myself a simple 'star rating' control.
It would have the properties:
StarCount (number of stars)
StarValue (number of stars highlighted)
I want to draw the stars using GDI+, have them highlight on mouse over, and change the StarValue when clicked.I have an idea on how to do this from experience with working with forms, but I'm having some difficulties with the Control development part. I couldn't find any tutorials which didn't inherit a control (such as a checkbox or button), and I have no idea how to make my control editable in the designer.
I think what I need to do is create StarCount as a property like this:

I also want to execute my drawing code at design time, so I can see the stars while laying out a form. as a side note to that, I don't know how to change the size of the control at run or design time, nor how to disable the user from changing it at design time.as a side note - I know that there are a few star rate controls already floating around the internet, but I do not like the quality of them (or at least the one's I've seen), they felt very windows 98. I'm trying to make something that will fit well into windows 7 (plus I want to implement custom images, but that can wait until I get it working)
I have a DLL with me in which i have created a component class. But as long as the project is open the Tool shows in the ToolBox, but the moment i open a new project, without the DLL project opened along with it, the Toolbox does not show me the Tool/Control/Component Class , which i have created. How do I register my component so that it shows in the ToolBox, other than the usual way of Selecting by Browsing
