Creating a custom textbox

Hi all,

I'm fairly new at C# and application development in general (I was trained as an embedded systems engineer...). Recently I've had to use C# in the development of a prototype .NET user interface. The old, unmanaged C++ version of the interface made use of a controls library which had specialised int/double text boxes which I emulated by manipulating the Textbox's KeyPress event. Because I find myself using this control in so many dialogues, I've been trying to look for a way to creating a class which inherits from the Forms.Textbox class which I can add onto the Designer from the Toolbox (I should add at this stage that I am using MS Visual Studio 2005).

Any help will be greatly appreciated

cheers!

You should have no problem with this - its quite straight forward.

All you need to do is create a class and derive it from the TextBox. Then you can override the OnKeyPress/OnKeyDown event(s) as necessary and do whatever work you would usually do against each instance.

Here's my simple example to get you started... it just MessageBox's every character you type.

public class AnnoyingTextBox : TextBox<br />
{<br />
<br />
    protected override void OnKeyPress(KeyPressEventArgs e)<br />
    {<br />
        MessageBox.Show(e.KeyChar.ToString());<br />
        base.OnKeyPress(e);<br />
    }<br />
}

Thanks for that...

I'll get cracking straight away on creating the class derived from Textbox, but when I am done how do I add this to the list of controls (the 'Toolbox' in Visual Studio 2005) where one can drag and drop controls onto the WYSIWYG designer? It's just that it's much easier to be able to do this when designing a dialogue rather than to manually type in the numbers and *hope* you get it in the right place...

cheers!

You estimate it based on how much you still need to download, and how much you're getting per second.

DoDragDrop and MouseClick event

Hi All,

I'm implementing drag/drop in my windows forms 2.0 / c# application.

In my control's MouseDown event handler, i'm calling DoDragDrop appropriately. But, the call to DoDragDrop seems to prevent other mouse events (MouseClick, DoubleClick, etc) from firing.

Is there a way round this? I need to be able to distinguish between a mouse-down drag starting event and a double click.

Thanks

I was doing something similar to what you are doing using DragDrop for a TreeView control and trying to use Click, Double Click, etc. and I found no way around it.

Hope this helps

Hi Mike,

Thanks for your post. If you're interested, i found the solution.

You're not supposed to call DoDragDrop from the MouseDown event. Instead, you should use the mousemove event, and call DoDragDrop where the L button is down and the mouse has moved outside of the rectangle centered around the point that the mousedown happened, of size SystemInformation.DragSize.

This example http://msdn2.microsoft.com/en-us/library/system.windows.forms.control.dodragdrop(vs.71).aspx[^] demonstrates the method perfectly.

I hope that helps you.

You mean via ASP.NET, or when you have a client app running on the target machine ? If the latter, then perhaps, but I doubt it. If the former, then, no way. Your C# code is never going to run on the client.

I am not usig ASP.NET but from my experience with php I can say this:

You have two solutions. The first is to generate the web page as shown to the user in the server. In the generated page, avoid using JavaScript, but create hard coded links.

The second solution is to detect that JavaScript is blocked (I am sure you can find the techniques on one of the many JavaScript sites) and kindly ask the user to switch JavaScript on.

Fortunately you cannot switch JavaScript on at the server side. This would cause a serious security leak for clients that chooses to block JavaScript. I think this is a reason why server side scripting is far more attractive than client side scripting.

The best way is to build your link the normal way, with a button or anchor tag.

.Net remoting and pass by reference

Hi all, I have a .net remoting system (server, client and remotable object). Now I need the client to be able to call a remote object method passing an object by reference as a parameter. That object is a class written by me and inherits from MarshalByRefObject, but I don't know how to set the configuration file: it keeps giving me security exceptions... The examples found over the internet didn't help me much. Someone could help me?

The actual exception message is:
System.Runtime.Serialization.SerializationException: Because of security restrictions, the type System.Runtime.Remoting.ObjRef cannot be accessed. ---> System.Security.SecurityException: Request failed.
at System.Runtime.Serialization.FormatterServices.nativeGetSafeUninitializedObject(RuntimeType type)
at System.Runtime.Serialization.FormatterServices.GetSafeUninitializedObject(Type type)
...

Thank you,
Alessandro
