该代码仅在一个操纵杆中工作，但如果我的计算机上连接了两个操纵杆，则另一个操纵杆无效。

我该怎么做？

先谢谢！

解决方案

API函数joyGetPosEx有两个参数，第一个参数代表游戏手柄的ID

您可以尝试将代码joyGetPosEx（0，myjoyEX）更改为joyGetPosEx（this.Id，myjoyEX）

This is my ff. codes...

**********************************************************************************

Imports System.Runtime.InteropServices

Public Class Form1

    Declare Function joyGetPosEx Lib "winmm.dll" (ByVal uJoyID As Integer, ByRef pji As JOYINFOEX) As Integer

    <StructLayout(LayoutKind.Sequential)> _
    Public Structure JOYINFOEX
        Public dwSize As Integer
        Public dwFlags As Integer
        Public dwXpos As Integer
        Public dwYpos As Integer
        Public dwZpos As Integer
        Public dwRpos As Integer
        Public dwUpos As Integer
        Public dwVpos As Integer
        Public dwButtons As Integer
        Public dwButtonNumber As Integer
        Public dwPOV As Integer
        Public dwReserved1 As Integer
        Public dwReserved2 As Integer
    End Structure

    Dim myjoyEX As JOYINFOEX

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

        ' Get the joystick information
        Call joyGetPosEx(0, myjoyEX)

        With myjoyEX
            Label10.Text = .dwXpos.ToString          'Up to six axis supported
            Label11.Text = .dwYpos.ToString
            Label12.Text = .dwZpos.ToString
            Label13.Text = .dwRpos.ToString
            Label14.Text = .dwUpos.ToString
            Label15.Text = .dwVpos.ToString
            Label16.Text = .dwButtons.ToString("X")  'Print in Hex, so can see the individual bits associated with the buttons
            Label17.Text = .dwButtonNumber.ToString  'number of buttons pressed at the same time
            Label18.Text = (.dwPOV / 100).ToString     'POV hat (in 1/100ths of degrees, so divided by 100 to give degrees)
        End With
    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        myjoyEX.dwSize = 64
        myjoyEX.dwFlags = &HFF ' All information
        Timer1.Interval = 200  'Update at 5 hz
        Timer1.Start()
    End Sub
End Class

That code is working in one joystick only but if two joystick attached on my computer, the other one doesn't work.

What will I do?

Thanks in advanced!

解决方案

The API function joyGetPosEx has two parameters, the first parameter represents the ID of the gamepad
You can try changing the code joyGetPosEx(0, myjoyEX) to joyGetPosEx(this.Id, myjoyEX)
