Two title bars active at the same time [modified]

Yes, exactly as the documentation in the link you gave.

I would only add, that both the server instances on my system are Express versions 2005 and 2008. Don't know if that would make any difference though.

I have a main form 'frmMain' and another form for tools 'toolBox' owned by the main form. I would like these two forms to always have appearance as if their both titlebars are active simultaneously. Example of such behaviour is in MS Paint: the tools window when it's undocked and the main window. How do i accomplish this?

Have you tried setting the TopMost property of your 'toolbox' window to true?

I did try, but it's the same. When one form gains focus, other's titlebar fades. And, besides, with topmost property, the form is above all forms, even the ones from other applications, and that is unwanted sideeffect. I did find an example how this could be achieved in VB.NET: http://www.andreavb.com/forum/viewtopic_3772.html, but my attempts to convert it have failed.

Take a look at this[^]. it uses the same techniques as the VB link you gave but it is in C#. Scroll down to the heading Painting the non-client area

Have a go at it, and come back if you get stuck.

I have the solution. Someone on MSDN forum showed me how to do it, and it's amazingly simple:

protected override void WndProc(ref Message m)
      {
          if (m.Msg == 0x86) // WM_NCACTIVATE
              m.WParam = (IntPtr)1;
          base.WndProc(ref m);
      }

I just placed this function inside both forms and it works. But there is still another problem. The forms are painted as active even when i activate some other application. That is not good. It brings confusion. I need to find a way to bypass these functions in both forms if another application gets activated. Any idea?

Extracting ID3 albumart with TagLib Sharp

18-Apr-09 11:07

Have a look at this[^]. Perhaps you can make a method from the principle used and then in WndProc do something like:

if ((m.Msg == 0x86) && (this.IsActiveApplication))
{
    m.WParam = (intPtr)1;
}

Hope this helps.

Im trying to extract albumart from ID3 tags using TagLib Sharp. I am able to get all other info except for the pictures, I cant seem to figure it out. Anyone have any experience with TagLib Sharp?

Heres my trouble:

Everything works fine but the pictures

private void songInfo(string url)
//Sets info for song info pane. The current URL being played
//is passed in; the labels are derived from the ID3 tags.
{
int i = 0;
TagLib.File file = TagLib.File.Create(url);

lblName.Text = file.Tag.Title;
lblArtist.Text = file.Tag.FirstPerformer;
lblAlbum.Text = file.Tag.Album;
lblYear.Text = Convert.ToString(file.Tag.Year);
foreach (TagLib.IPicture pic in file.Tag.Pictures)
{
~~pboxAlbumArt.Image = pic.Data;~~
}
}

Heres where I hit trouble, doing this gives me an error saying it cannot convert a bytevector to an image. Firts of all is this the correct way to do this nd if so, how would I go about converting a bytevector to an image?

Thanks
Jon

See it,It took me whole half day to figure out that code.

Finally i got to know that something called MemoryStream existed which made me free from using FileStream which i used earlier..
The code is quite short and neat finally.

Running JIT on command

Hey everybody!

I was wondering, is there a way to execute JIT on the whole program at startup?
Lets say I have a small application that I want to be completely compiled before it actually starts running (like a C++ program), is there a way to do that?

Thanks!

You can try RuntimeHelpers.PrepareMethod. It is in System.Runtime.CompilerServices. Refer to the MSDN documentation before you try it out.
