Bonjour,
Voila je commence un projet qui consiste à dessiner n'importe ou sur l'écran en appuyant sur le scroll de ma souris ce qui créera un traçage rouge pendant que le clique est enfoncer ensuite en récuperant les données x et y de chaque pixel pour les analyser...
Mon problème est que je récupère les données x et y selement dans la zone de ma windows form et mon but serais qu'il n'ait pas de winform mais juste une application qui tourne en arriere plan avec un icone dans la barre de notif.
Voici mon code :
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;
using System.Runtime.InteropServices;
namespace Reconnaissance
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
public delegate int HookProc(int nCode, IntPtr wParam, IntPtr lParam);
//Declare the hook handle as an int.
static int hHook = 0;
//Declare the mouse hook constant.
//For other hook types, you can obtain these values from Winuser.h in the Microsoft SDK.
public const int WH_MOUSE = 7;
private System.Windows.Forms.Button btnHook;
//Declare MouseHookProcedure as a HookProc type.
HookProc MouseHookProcedure;
//Declare the wrapper managed POINT class.
[StructLayout(LayoutKind.Sequential)]
public class POINT
{
public int x;
public int y;
}
//Declare the wrapper managed MouseHookStruct class.
[StructLayout(LayoutKind.Sequential)]
public class MouseHookStruct
{
public POINT pt;
public int hwnd;
public int wHitTestCode;
public int dwExtraInfo;
}
//This is the Import for the SetWindowsHookEx function.
//Use this function to install a thread-specific hook.
[DllImport("user32.dll", CharSet = CharSet.Auto,
CallingConvention = CallingConvention.StdCall)]
public static extern int SetWindowsHookEx(int idHook, HookProc lpfn,
IntPtr hInstance, int threadId);
//This is the Import for the UnhookWindowsHookEx function.
//Call this function to uninstall the hook.
[DllImport("user32.dll", CharSet = CharSet.Auto,
CallingConvention = CallingConvention.StdCall)]
public static extern bool UnhookWindowsHookEx(int idHook);
//This is the Import for the CallNextHookEx function.
//Use this function to pass the hook information to the next hook procedure in chain.
[DllImport("user32.dll", CharSet = CharSet.Auto,
CallingConvention = CallingConvention.StdCall)]
public static extern int CallNextHookEx(int idHook, int nCode,
IntPtr wParam, IntPtr lParam);
public static int MouseHookProc(int nCode, IntPtr wParam, IntPtr lParam)
{
//Marshall the data from the callback.
MouseHookStruct MyMouseHookStruct = (MouseHookStruct)Marshal.PtrToStructure(lParam, typeof(MouseHookStruct));
if (nCode < 0)
{
return CallNextHookEx(hHook, nCode, wParam, lParam);
}
else
{
//Create a string variable that shows the current mouse coordinates.
String strCaption "x " +
MyMouseHookStruct.pt.x.ToString("d") +
" y = " +
MyMouseHookStruct.pt.y.ToString("d");
//You must get the active form because it is a static function.
Form tempForm = Form.ActiveForm;
//Set the caption of the form.
tempForm.Text = strCaption;
return CallNextHookEx(hHook, nCode, wParam, lParam);
}
}
private void btnHook_Click(object sender, EventArgs e)
{
if (hHook == 0)
{
// Create an instance of HookProc.
MouseHookProcedure = new HookProc(Form1.MouseHookProc);
hHook = SetWindowsHookEx(WH_MOUSE,
MouseHookProcedure,
(IntPtr)0,
AppDomain.GetCurrentThreadId());
//If the SetWindowsHookEx function fails.
if (hHook == 0)
{
MessageBox.Show("SetWindowsHookEx Failed");
return;
}
btnHook.Text = "UnHook Windows Hook";
}
else
{
bool ret = UnhookWindowsHookEx(hHook);
//If the UnhookWindowsHookEx function fails.
if (ret == false)
{
MessageBox.Show("UnhookWindowsHookEx Failed");
return;
}
hHook = 0;
btnHook.Text = "Set Windows Hook";
this.Text = "Mouse Hook";
}
}
}
}
Si quelqu'un pourait m'aidez à touver une solution sa serais sympa
Merci
