Usually if you're using the game port you've probably writing a game, and so will have DirectX SDK - if not then have a look at it.
In DirectX there is a name space called DirectInput in the DirectX SDK that allows direct access to any Joystick/Mouse/Keyboard etc.
The code is pretty easy, if you look at the samples, but it does mean that running you app will need everybody to have directX installed
Haven't tried to access directly but you probably will have some difficulty - as C# is supposed to hide you from accessing the H/W directly.

I want to open and stop the Video files in the WindowsMediaPlayer through Windows application. I am using a third party GUI software, so I wont be able to add WMPlayer control on to my application. I just need to control the WMPlayer by the code.
The below mentioned sample code is able to open the player and play the Video file. But the stop and close functionalities are not working in this.
Can U please tell me how to control the mediaplayer through code. I want to implement functionalities like 'Pause', 'Fullscreen' etc..
public partial class Form1 : Form
{
private WindowsMediaPlayerClass wmPlayer = new WindowsMediaPlayerClass();
//private WindowsMediaPlayer wmPlayer = new WindowsMediaPlayer();
public Form1()
{
InitializeComponent();
}
private void Play_Click(object sender, EventArgs e)
{
wmPlayer.openPlayer(@"C:\SampleVideo.wmv");
}
private void Stop_Click(object sender, EventArgs e)

Hello,
I am receiving data from network. The C# application is able to get correct data by BinaryReader and some methods like ReadByte() or ReadUint16(). Only the ReadString() method do not stop reading if in the byte stream is a zero. What could be the reason?
Thanks

You haven't posted all of the relevant code. For starters, where have you defined these variables? Do you have them in a class? If you're trying them outside of a class, directly in a namespace, you're out of luck. Variables and methods MUST be inside a class. Except for delegates, I think, but that is a different story....
Cheers,
Vikram.

Hi there.
I have loaded a picture into a DB. Now when i take it out again, I save it as a Byte[] variable. What i want to do, is to use that Byte[] variable with the information and display it in an imageBox.
Can anyone help me with this?
Thanks

Save the byte array to a stream.Then use Image.FromStream(ms) to create a Image object.
MemoryStream ms=new MemoryStream(bytes);
Image img=Image.FromStream(ms);
|
|
|
|
|
Thanks, it works.
But do you how i can use that Image in an imagebox? i am getting a cannot implicitle convert type 'System.Drawing.Image' to 'System.web.UI.Webcontrol.Image'

Im trying to implement a simple find text on a editor im working on.
On my find form, i have this button called "Find", here is the code for when you press it:
private void FindButton_Click(object sender, EventArgs e)
{
// Initialize the return value to false by default.
int returnValue = -1;
// Ensure that a search string has been specified and a valid start point.
if (FindTextBox.Text.Length > 0 && 0 >= 0)
{
// Obtain the location of the search string in richTextBox1.
int indexToText = EditingArea.Find(FindTextBox.Text, 0, RichTextBoxFinds.MatchCase);
// Determine whether the text was found in richTextBox1.
if (indexToText >= 0)
{
returnValue = indexToText;
}
}
}
But, when i try to build the solution, i keep getting these two error:
Error 1 (Warning - not major but i wanna get rid this stupid warning)
Solution_Name.Editor.ContextMenu' hides inherited member 'System.Windows.Forms.Control.ContextMenu'. Use the new keyword if hiding was intended. C:\Users\Admin\Documents\Visual Studio 2005\Projects\Solution_Name\Solution_name\Editor.Designer.cs
Error 2 - (Critical error, wont let me compile at all)
The name 'EditingArea' does not exist in the current context
The "EditingArea" is the name of the RichTextBox on the main form "Editor". The "Find" form is also on the same solution, same project. So, why can't it find it???
|
|
|
|
|
I decided to add the namespace of the editor front of it like this:
Editor.EditingArea.Find(....
Now, I got this error:
Editor.EditingArea is inaccessible due to its protection level
So, i went back to my main form and made the RichTextBox (called Editor) and made the member "public" and tried to build again. Now im getting this error:
An object reference is required for the nonstatic field, method, or property
How do i fix this? Im i even doing the "Find Text" correctly?

I think I get it. You're doing the type of thing where you have your main editor screen, and then a Find dialog pops up over the editor, like the Visual Studio find dialog does.
You want the Find to call back to the editor to highlight the search text.
You're making the call to Find() correctly, but you need a reference to the actual RichTextBox that is your editor.
My suggestion would be to either
a) raise an event from your Find dialog telling the main editor that a search has been requested, and let the editor perform the search; or
b) pass a reference to the RichTextBox into the Find dialog.
Approach b) is the easiest, but approach a) is more in line with OOP principles, and it is more extensible (what if you decide you want to expand the search capabilities.. for everything you add, you'll have to pass new information between the forms, rather than just putting it all into an event).

Patrick

Thanks patrick for that suggestion, since im very new to c#, i haven't got the slightest idea what you've just said...
While trying to figure this "Find Text" thing out, i came up with this:
Editor form = new Editor();
int position = form.EditingArea.Find(FindTextBox.Text, 0, RichTextBoxFinds.None);
form.EditingArea.SelectionStart = form.EditingArea.SelectionStart + position;
but everytime i type into my editor and try to look for it, the program keeps trowing exception that -1 is not a valid selection start.
Can anyone show me how in the world you implement a simple text search for a RichTextBox ?
|

|
|
|
The error is bcos the value of position will always be ZERO.
Reason:
=======
Editor form = new Editor();
--This will create a new form window
which will have the RichtextBox control without any text.
So, obviously the Find function will retrun -1.

So how can i work with another form's content without creating a new instance of it?
What you just said makes sense to me, however, i have no idea how to fix this. A suggestion would be much appreciated...
