Developer's Corner / Forms calls a class, class interacting with a form

« on: November 21, 2008, 01:21 PM »

If I have a textbox in a form called 'textbox' and a class called 'class' is there any way of doing this?

Form1:
textbox.text = "";
Class class = new Class();
class.runfunction()

Class:
public void runfunction()
{
form1.textbox.text = "Some text"; // This would never work, but how could it?
}

Developer's Corner / C# Drag and Drop fail

« on: November 11, 2008, 12:30 PM »

Hi all, I'm doing really badly on my first try at a drag and drop. I'm trying to have a listBox that can have a file dragged onto it from Windows Explorer

From the very simple example here - http://support.microsoft.com/kb/307966 I have

Set AllowDrop on the list to TRUE
Set the event DragDrop
Set the event DragEnter

I have the following code

Code: C# [Select]

private void listFilesToConvert_DragEnter(object sender, System.Windows.Forms.DragEventArgs e)
        {
            // DEBUG
            MessageBox.Show("DragEnter");
 
            if (e.Data.GetDataPresent(DataFormats.FileDrop))
                e.Effect = DragDropEffects.All;
            else
                e.Effect = DragDropEffects.None;
        }
 
        private void listFilesToConvert_DragDrop(object sender, System.Windows.Forms.DragEventArgs e)
        {
            // DEBUG
            MessageBox.Show("DragDrop");
            
            string[] s = (string[])e.Data.GetData(DataFormats.FileDrop);
            int i;
            for (i = 0; i < s.Length; i++)
                listFilesToConvert.Items.Add(s[i]);
 
        }

I can't say I understand it all, but it looks very similar to other code on the net. It's probably something simple but I can't work it out.

Neither debug message boxes fire.

Cheers

Developer's Corner / Q2 [Ans.] Killing a created process from outside the function that creates it

« on: November 02, 2008, 04:27 AM »

Another question I'm stuck on.

I have two forms (for this example) called Main and Ffmpeg. Inside main there is a [Start] and a [Cancel] button. There is a Start_Clicked function and a Cancel_Clicked function.

Inside Start_Click I start ffmpeg (Ffmpeg ffmpeg = new Ffmpeg). This ffmpeg class opens up ffmpeg.exe and sends some arguments. (The code is in https://www.donationcoder.com/forum/index.php?topic=15549.0)

Now my question is, how can I send proc.Kill(); to ffmpeg? The Cancel_Clicked function doesn't know what ffmpeg is.

Advanced thanks for your help. Learning languages is damn near impossible without people like yourself that help!

Hi there. I'm back to C# and am getting by with web examples and a few books. However I'm stuck.

I've created a process and it happens to be FFMPEG
