Re: notepad.exe - C# Discussion Boards

I have this problem:

I want to open in a notepad some text from my exe application. Should be something like view source in IE.

I have a textbox where I have a lot of text. And, because it's difficult to edit text in a text box, I thought that is much easy to send that text to a notepad window. BUT... I don't want to save the text before to open it in notepad.

Any suggestion?

Thanks!

Wat do u mean ":it's difficult to edit" do u want to format(font/size) the text or juz copy/paste options.. if you want format then design a notepad of urself..(or search google to get the same) or use richtext box for minimal formatting.
RB contains builtin functions to format/edit

Could it be that you do not have the MultiLine property set to true. That could make a lot of different when editing a zillion line text file. When you have multiline set to true than you can edit the width/height of the control so more text is visible both vertically and horizontally.

What i need is a way to paste some text from another application, to a running notepad.

You could try to transfer the text using the clipboard:
select and copy in your app, then send key events for CTRL/V to the window of your
target app. You would have to find the process ID, its main window, and perform
either a SendMessage, SendKey or SendInput.
There is an MSDN article explaining SendInput is "more reliable" than SendKey ?!?!

I have not done this myself (I created my own editor though).

Thanks Luc,

I'll try to do what u suggested - and the idea with my editor is also good. It's not so difficult to do an simple text editor.

Using the clipboard like that is not good practice. What if the user has something in the clipbaord that they want to be there?

What's so bad about saving a temp txt file to open with notepad?

Creating and invoking instance of Action using reflection

29-Jan-07 0:37

If I save the file and open it in a notepad after this, when the user do save, the file is saved in that location, and this is what i want to prevent. I want that notepad, when the user chose to save that text, to open a save dialog, and to ask the user the name/location for that file.

And about the clipboard.... the things stocked in it are temporary, and supposedly are not so important! (or can be recovered at any time)

Hi,

I'm having a problem with generics and reflection, trying to create an instance of a System.Action<> delegate and invoking it. I'm doing this:

// Create a type for Action<string>
Type type = typeof( Action<> ).MakeGenericType( new Type[] { typeof( string ) } );

So far so good. However, I can't figure out how to use Activator to create an instance of this so I can invoke it. The constructor for Action<> takes a "void (string) target", and I don't know how to express this in a call to Activator.CreateInstance. I.e., following the line above:

System.Delegate del = (System.Delegate)Activator.CreateInstance( type, new object[] { what_goes_here? } );

Anyone have a clue how to achieve this?

You can use the WndProc for the form and filter the a combination of the following events:

private const int WM_NCLBUTTONDBLCLK = 0xA3;<br />
private const int WM_NCLBUTTONDOWN = 0xA1;<br />
private const int WM_NCLBUTTONUP = 0xA2;

When the event fires you can change the size of the form that received the event. If the form height is lessthan or equal to 0 then change the height to the normal height. If the form height is the normal height then reduce the height to 0.

System.Net.NetworkInformation.NetworkChange.NetworkAvailabilityChanged += new System.Net.NetworkInformation.NetworkAvailabilityChangedEventHandler(NetworkChange_NetworkAvailabilityChanged);

and in the event handler check for the Internet availability

void NetworkChange_NetworkAvailabilityChanged(object sender, System.Net.NetworkInformation.NetworkAvailabilityEventArgs e)<br />
        {<br />
            if (!e.IsAvailable)<br />
            {<br />
                MessageBox.Show("N/W DISCONNECTED"); <br />
            }<br />
        }

This will work, but it is really only going to show if you are connected to the network. This can be different than being connected and able to hit the internet.

You would also need to use a WebRequest or the Ping class and attempt to access a URL that you are reasonably sure will always be available.
