How can I get detailed information?

Applies To: C++Builder 1 or higher
Category: Knowledge Base

 

1.

  Start a new project using File | New Application.

 

2.

  Add a ListView. Insert 2 columns: Property and Value.

 

3.

  Insert in your code:

 

void TForm1::Add(String property, String value)

{

    TListItem *item = ListView1->Items->Add();

    item->Caption = property;

    item->SubItems->Add(value);

}

 

This function will help us add information to the ListView more easily.

 

4.

  Edit your header file:

 

private:

    void Add(String property, String value);

 

5.

  Add a Button. Double-click its OnClick event:

 

void __fastcall TForm1::Button1Click(TObject *Sender)

{

    JOYCAPS caps;

    JOYINFO info;

 

    // Get information about the first joystick

    // Change this value if using multiple joysticks

    const int number = 0;

 

    MMRESULT error = joyGetPos(number, &info);

    if(error != JOYERR_NOERROR)

    {

        ShowMessage("The joystick #" + IntToStr(number)

            + " was not found.");

        return;

    }

 

    joyGetDevCaps(number, &caps, sizeof(JOYCAPS));

 

    Add("Manufacturer identifier", (String)caps.wMid);

    Add("Product identifier", (String)caps.wPid);

    Add("Product name", (String)caps.szPname);

    Add("Driver OEM", (String)caps.szOEMVxD);

    Add("Registry key", (String)caps.szRegKey);

    Add("Number of buttons", (String)caps.wNumButtons);

    Add("", "");

    Add("Minimum X", (String)caps.wXmin);

    Add("Maximum X", (String)caps.wXmax);

    Add("Minimum Y", (String)caps.wYmin);

    Add("Maximum Y", (String)caps.wYmax);

    Add("Minimum Z", (String)caps.wZmin);

    Add("Maximum Z", (String)caps.wZmax);

}

 

6.

  Insert #include <mmsystem.h>.

 

The joyGetDevCaps multimedia function allows you to get specific information about a joystick.
