sample source code Options

[toyoPon3]

Hi.

I want to program a foobar2000 component which shows the album art.
And, I am searching the site which has the sample source codes of component.
Please tell me the URL of the site shown above.

I prepared the SDK by reading this site.

[Zao]

There is a pinned thread named "Pinned: Developer Tutorials" in this forum.

[toyoPon3]

To Zao.

Thank you for your reply.
Unfortunately, I could not find the site from the thread that you taught.
(Maybe, my reading skill was not good.)

But I found the URL shown in below.
http://foosion.foobar2000.org/components/

thank you.

Source code for components is also here:

I wanted to add the dialog window to foobar2000 by using VC++ 2010 Express. (I can not buy the Professional Edition)
I post my memo for someone who is wondering like me.
------
Outline.
Step1:Add "pref.cpp" to your project.
Step2:Add "resource file" to your project.

pref.cpp and resource file are shown below.
------

I added my tag to "the Preferences pages" by the referring to the topic shown below.
Especially, pref.cpp(Mr.foosion exsample Post#3) was good help for me.
http://www.hydrogenaudio.org/forums/index....mp;#entry373489

And, I made the resource file by using the ResEdit(free tool).
ResEdit:http://www.resedit.net/
I modified two lines for changing from the parent window to the child window.
Note:VC++ Express dose not supply "the res Edit function" to the programer.

My resource file is shown below.

CODE

#include <windows.h>
#include <commctrl.h>
#include <richedit.h>
#include "resource.h"

// Dialog resources
LANGUAGE LANG_NEUTRAL, SUBLANG_NEUTRAL
IDD_DIALOG1 DIALOGEX 0, 0, 186, 95
STYLE DS_SETFONT | WS_CHILD // <- Change
//CAPTION "Dialog" <- Comment out
FONT 8, "Ms Shell Dlg", 0, 0, 1
{
DEFPUSHBUTTON "OK", IDOK, 129, 7, 50, 14
PUSHBUTTON "Cansel", IDCANCEL, 129, 24, 50, 14
CTEXT "This is test", IDC_STATIC, 13, 22, 50, 13, SS_CENTER
}

Although this example is still working, it is outdated and the user will get a warning on this. To avoid this preferences_page_3 instead of preferences_page should be implemented.

And, I made the resource file by using the ResEdit(free tool).
ResEdit:http://www.resedit.net/
I modified two lines for changing from the parent window to the child window.

Modifying anything manually is not necessary. Just set the Style to Child in the properties pane for the dialog.

To Mr.fbuser

Thanks for your reply.

I changed from preferences_page to preferences_page_v3 on your advice.

I read the topic shown below.
http://www.hydrogenaudio.org/forums/index....mp;#entry693611

But I think that this topic is written for VC++ Professional user.
Is it right?

Then, what should I insert "XXX"?

CODE

virtual preferences_page_instance::ptr instantiate(HWND parent, preferences_page_callback::ptr callback)
{
return XXXX;
}

Please, tell me where is wrong.

With only the few code fragments you provided, it is difficult. By I guess with preferences_page_liveshowtagger you implemented preferences_page_v3. You also need to implement preferences_page_instance as shown in the thread you mentioned.

To Mr.fbuser

I understood that I need "implement preferences_page_instance".
And I found some sample codes.

But all sample codes are for VC++ Professional user.
* The code needs "CDialogImpl<>".
But I am VC++ Express user.

Then, must I make the function shown below by myself?

1.t_uint32 get_state();
2.void apply();
3.void reset();
4.HWND get_wnd();

Is it right?
Or is there the class for VC++ Express user?

[toyoPon3]

I implemented my_preferences_page_instance(sub class of preferences_page_instance).
And I finish compiling.
It shows the tags "Sample Page".
But it dose not show the dialog.

I insert the debug line "console::info("Call ConfigProc");" in ConfigProc().
"Console window" shows "Call ConfigProc" only several times.
After that, "Console window" does not show any line.
Where is wrong?

You should call my_preferences_page_instance::Create() in the constructor of my_preferences_page_instance and assign the resulting Handle to a class member (e.g. m_wnd). my_preferences_page_instance::get_wnd() must return the handle of your dialog not the parent handle as in your code.

So, your code could look like this

CODE

#include "resource.h"
#include "../SDK/foobar2000.h"
#include "../helpers/helpers.h"

static const GUID guid_prefs_tagging = { 0x563107c3, 0xfc7d, 0x4022, { 0xa8, 0x72, 0xa8, 0x2a, 0x2b, 0x3f, 0xd5, 0x25 } };

static preferences_branch_factory foo_preferences_branch_tagging(guid_prefs_tagging, preferences_page::guid_tools, "Tagging");

const char strText[] = "sample test";

static BOOL CALLBACK ConfigProc(HWND wnd, UINT msg, WPARAM wp, LPARAM lp)
{
console::info("Call ConfigProc");
switch (msg)
{
case WM_INITDIALOG:
{
uSetDlgItemText(wnd, IDC_EDIT1, strText);
}
break;
case WM_COMMAND:
break;
default:
return FALSE;
}
return TRUE;
}

class my_preferences_page_instance : public preferences_page_instance
{
protected:
t_uint32 m_state;
HWND m_parent;
HWND m_wnd;
preferences_page_callback::ptr m_callback;

public:
my_preferences_page_instance(HWND parent, preferences_page_callback::ptr callback) :
m_callback(callback),
m_parent(parent),
m_state(preferences_state::resettable){m_wnd=Create(m_parent);}


HWND get_wnd()
{
return m_wnd;
}

t_uint32 get_state()
{
return m_state;
}

// Applies preferences changes.
void apply()
{
console::info("Call apply");
m_state = preferences_state::resettable;
m_callback->on_state_changed();
}

// Resets this page's content to the default values.
// Does not apply any changes -
// lets user preview the changes before hitting "apply".
void reset()
{
m_state |= preferences_state::changed;
// m_callback->on_state_changed();
}

HWND Create(HWND parent)
{
console::info("Call create");
return uCreateDialog(IDD_DIALOG1, parent, ConfigProc, 0);
}
};


static const GUID guid_prefs_sample = { 0x13be3cd2, 0xbff3, 0x42cc, { 0x96, 0xda, 0x7f, 0xfc, 0x7a, 0x4a, 0x3d, 0x6 } };

Mr.fbuser.

Thanks.
My program moves as planned.

I have to study about win32 API.
