The scope of your mouse event handler is based on the form - that's what you specified when you hooked it up in your OnLoad. Change the scope there to be the picture box and you'll be good to go - to do this, change
MouseDown += new MouseEventHandler(MyMouseDown); to
picDrawing.MouseDown += new MouseEventHandler(MyMouseDown); (Assuming you named your picture box picDrawing).

I have a program from which I am calling a subordinate form with the axmediaplayer name axWMP.
I want the subordinate form to run from the keyboard but the key strokes are not seen unless I click on the form. It seems that the form loses focus because the keys strokes go to my compiler not the form.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace IRmediacontrol
{
public partial class WMP : Form
{
string fname = "";
public WMP(string filename)
{
InitializeComponent();
fname = filename;
}
private void axWMP_KeyPressEvent(object sender, AxWMPLib._WMPOCXEvents_KeyPressEvent e)
{
label1.Text = "key press = " + e.nKeyAscii.ToString();
}
private void button1_Click(object sender, EventArgs e)
{
axWMP.URL = fname;
axWMP.Ctlcontrols.play();
}
}
}
Any help would be appreciated!

Just add
axWMP.Focus(); after you make the .play() call.
|
|
|
|

I had tried that prior to the .Play call and it didn't work. Your suggestion solved the problem.
Many Thanks.

I'm afraid I still have the problem. I thought that the problem had been solved as clicking on the button caused the key commands to work. In actuality clicking the button was bringing the focus to the form. Here is the code with no button which loses focus.
public WMP(string filename)
{
InitializeComponent();
this.axWMP.KeyPressEvent += new AxWMPLib._WMPOCXEvents_KeyPressEventHandler(this.axWMP_KeyPressEvent);
fname = filename;
axWMP.settings.autoStart = false;
axWMP.URL = fname;
axWMP.Ctlcontrols.play();
axWMP.Focus();
}
private void axWMP_KeyPressEvent(object sender, AxWMPLib._WMPOCXEvents_KeyPressEvent e)
{
label1.Text = "key press = " + e.nKeyAscii.ToString();
}

I see what you want now, and no, the .Focus() won't do the trick.
My question is whether you are trying to capture keystrokes in a generic manner and then pass on the relevant ones to the child form?
The issues may lie with where the focus lies. The keypress arguments are going to be sent from whichever control has the focus, not the form itself, so you won't see the event using the hooks you have. What you need to do is capture the keypress event from whichever control happens to have the focus on the active form and then pass the keystroke event down to the sub form for it to use it. If you tell me which version of Studio you're using, I can package up a sample I just made to demonstrate this and send it to you. You can email me that at [edited out now that you've gotten it], if you like.

If I click on the form all works as it should. I am writing a mediaplayer that functions from a IRremote so I dont want to have to click on the form with a mouse in order to read the key commands.

If you want to do that again, there is an Email button at the bottom of your message which means you don't have to expose your email address to Googles' page cache at all.
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

Thanks. It's ok though, because I expose my "utility" email address and not my primary one.

Handling the problem by e-mail keeps other interested parties from seeing the solution to a problem. If it is too much for a forum post, you might consider writing a tip&trick or even an article about it.

Your right. I finally found the answer to the problem. The child form was not the problem. In the parent form I had done this:
this.WindowState = System.Windows.Forms.FormWindowState.Minimized;
Form2 dlg = new Form2(fname);
dlg.ShowDialog();
For some reason this causes Form2 to be inactive I know not why.

The main form represents the entire app (when it closes, the app exits). I'm surprised the dialog was even showing, if you had minimized the main form later on, the dialog would have disappeared too (try right-clicking minimize on the task bar on any app).
BTW: these special things you just showed should have been mentioned earlier...
Cheers.

Agreed. I didn't even think to ask that yesterday.

Hey Luc,
Rather than span the forum with numerous posts along the way, the idea was to figure out what was wrong and then post that, not the entire process of getting there.
Cheers

Have you considered using the ProcessCmdKey overload or event ??? instead of keypress event
With great code, comes great complexity, so keep it simple stupid...

Hello everybody,
I don't know if here is the right section, if not, please change.
I need some support with this questions.
I will present here my problem:
Suppose I want a software to give to someone to encrypt text, and to encrypt the program should use the privatekey ( that only I know, but the program will need to encrypt data, so it must be hidden there) and to decrypt it should use the public key, that I can give to anyone.
So, now:
I have a private key and a public key, generated by open ssl: privatekey.pem and publickey.pem
Now, I need to be able to use those keys to encrypt and decrypt data.
the thing is, how I load the .pem to the program?
As I readed I need to load it to rsaparameters, but how I do it?
The type of the keys are:
-----BEGIN RSA PRIVATE KEY-----
MIICXQIBAAKB...
and
-----BEGIN PUBLIC KEY-----
MIGfMA0GCSqGSIb3DQEBA...
Any help would be very usefull, since I'm having a lot of troubles making it.

Alegria_Lee Thanks a lot!
I will study this example today, and try to solve my problem. But this seams really helpfull.
I'll post here if I get it working or not. If you dont mind, stay checking here.

Ok, It helped me a lot. Now I'm able to use my own private/public keys. Without any problem
Now, the thing is:
I need to encrypt the data using the private key.
And I need to decrypt it using the public key.
But RSA dont let me... I can encrypt with the private key, but them, I cant decript with the public one.

well, but is good and is working 
thank you a lot.
|
|
|
|
|
You're welcome.
By the way,Have you find out a solution to solved your problem ?(" encrypt with private key and decrypt with public key ")
AS i know,RSA can not seem to do so .
|
|
|
|
|
yes, is not possible.
But I noticed that what I wanted it could be made with the method: signdata
It signs data with private key and unsign with public key =)
