Actually it is very easy to parse ID3V1 tags. Simply seek the file pointer of an mp3 file to the end minus 128 bytes. You can then read the 128 from this pointer until the EOF (End of file).
If the first three bytes equal "ID3" you know that there is an ID3V1 tag at the end.

However, I don't know how ID3V2 tags work Frown | :(

Actually the ID3v1 marker string is 'TAG' not 'ID3'. </nitpick;> Wink | ;)

I wrote something a while ago that uses filenames for song names and folder names for artist and album. ID3V1 is a doddle, it's just sitting on the end of the mp3 ( which is why if you're *ahem* downloading an mp3 and don't get it all, there's no id3 info ). ID3V2 is compressed though, I used a class I found on the net ( and fixed, as I recall ) to do it. If you have no joy and want ID3V2, just LMK and I'll send you the class. I can't post it to CP as I did not actually originally write it.

Hi Christian,

I would love to get that ID3V2 class you spoke of! I always use V2, so V1 won't work for me. I don't plan on selling (or widely distributing) this application.

Thanks!!!

Hello,

When clicking on a CEdit box, I would like the entire contents of the box to be selected (so that the user can simply overwrite existing text instead of manually backspacing over the existing contents). I have searched and didn't find anything on MSDN help. When a user tabs to the CEdit box, the entire contents are selected--the exact behavior I want for a user mouse-click. Any suggestions?

Thanks!

override OnSetFocus (handle EN_SETFOCUS) for your edit control, and then call m_myEdit.SetSel(0,-1);

Hi Chris,

I've done just that, and no dice. I verified that it gets called with TRACE but the edit box still puts the insert cursor where the mouse was when I clicked on it. Do I need to call more items from the function? Here's the function....

void CDiagGoalSched::OnSetfocusEditDue() <br />
{<br />
     // This doesn't seem to work...  I want a mouse click to select entire contents.<br />
     TRACE0("SET FOCUS...");<br />
     m_CtrlEditDue.SetSel(0, -1);<br />
}

Thanks!

try this:

::PostMessage(m_edit.m_hWnd, EM_SETSEL, 0, -1);

Bingo! Why does this work and not the first one? Is it the order of window messages in the queue? (I.e., the m_EditCtrl.SetSel() was before the Edit's translation from mouse position to cursor position?)

Thanks!
