IPC_SETPLAYLISTPOS with IPC_CHANGECURRENTFILE

[Joel]

I'm trying to move my playlist files path to another location and update the list with the new paths:

code:


p = (HWND)SendMessage(w, WM_WA_IPC, IPC_GETWND_PE, IPC_GETWND);

	total = SendMessage(p,WM_WA_IPC,IPC_PE_GETINDEXTOTAL,0);



	for ( ;index < total; index++)

	{

		sfos.pFrom = (TCHAR*)SendMessage(w,WM_WA_IPC,index,IPC_GETPLAYLISTFILE);

		if (SHFileOperation(&sfos))

		{

			TCHAR new_path[MAX_PATH];

			TCHAR path[128];

			SendMessage(w,WM_WA_IPC,index,IPC_SETPLAYLISTPOS);

			StripPath (sfos.pFrom, path);

			wsprintf(new_path,"%s\\%s", sfos.pTo, path);

			SendMessage(w,WM_WA_IPC,(WPARAM)new_path,IPC_CHANGECURRENTFILE);

		}

	}

the operation copy/move is done correctly, but seems that the playlist entry doesn't reflect the new path item, any helps?

Ok, I change my code to keep it "cleaner", now Winamp crash

code:


int do_op (HWND parent, int op, const TCHAR *src, const TCHAR *dist)

{

	SHFILEOPSTRUCT sfos = {0};

	sfos.hwnd = parent;

	sfos.fFlags = FOF_NOCONFIRMATION|FOF_SILENT|FOF_NOERRORUI;

	sfos.wFunc = op == COPY ? FO_COPY : FO_MOVE;

	sfos.pTo = dist;

	sfos.pFrom = src;

	return SHFileOperation(&sfos);

}



void do_it (HWND w, HWND d, int op)

{

	

	TCHAR dir[MAX_PATH];

	int index;

	int total;

	HWND p;

	

	GetDlgItemText (d, IDC_EDIT1, dir, sizeof(dir)+1);

	index = 0;

	p = (HWND)SendMessage(w, WM_WA_IPC, IPC_GETWND_PE, IPC_GETWND);

	total = SendMessage(p,WM_WA_IPC,IPC_PE_GETINDEXTOTAL,0);



	for ( ;index < total; index++)

	{

		TCHAR *src_file = (TCHAR*)SendMessage(w,WM_WA_IPC,index,IPC_GETPLAYLISTFILE);

		TCHAR dist_file[MAX_PATH];

		TCHAR path[128];

		StripPath (src_file, path);

		wsprintf(dist_file,"%s\\%s", dir, path);

		if (!do_op (w, op, src_file, dist_file))

		{

			SendMessage(w,WM_WA_IPC,index,IPC_SETPLAYLISTPOS);

			SendMessage(w,WM_WA_IPC,(WPARAM)dist_file,IPC_CHANGECURRENTFILE);

		}

	}

}

ok, my error was in my StripPath function, now works as expected

heh, didn't i ask if it was stripping and forming the path correctly in irc
