Actually it's not a music player, it is a free software for learning English vocabulary. It shows the words and sample sentences on desktop and play the audio. There is a timer to control how often the word and sentence will be changed, ect. I want to improve the dispaly effection for current version. Most of the current users are still using .net 2.0 on Windows XP.I need a main upgrade if I use WPF, it's also new to me. More than 20000 users have instaleld the software, but not too many people use it every day. I will say about 600 users run it today.

I am not a professional programer, I just do this in my spare time.

You see I have no problem drawing the string on the form or label, but the difficult part is making the form transparent to the desktop and keep the string beautiful. Since the string need be moved around, I don't think capture the back image and draw it under the string is a good idea. It will make it flashing when move it.

I tird to find an article about this but only find one writing in c++.

I really appreciate you spend your time on my question. Thank you!

I found very similar example using c++ . You can download and run it, it's very small application, but exactly what I need.http://www.codeproject.com/KB/GDI-plus/DesktopLyrics.aspx
The problem for me now is I am not familiar with C++. If somebody can translater it to c#, that will be perfect solution for me. Thanks a lot in advance!

Thank you for replay. But WPF needs .net 3.0, my current application is running on .net 2.0.

I found this article "Desktop Lyrics"excactly doing the same thing. http://www.codeproject.com/KB/GDI-plus/DesktopLyrics.aspx But it is written by c++. I noticed ths steps:
1. Create a compatible bitmap.
2. Draw on the bitmap.
3. Draw bitmap on the device content.
4. Invoke the UpdateLayeredWindows().
Then I found UpdateLayeredWindows maybe the API I need. Then I googled and found this article http://www.vcskicks.com/splash-screen.php. So I start to study both the article.
I believe this is the direction I should go.

Thank you for your explanation. "Use the control, and in its Paint (or OnPaint) draw your 2 layers: background picture first, you semi-transparent layer with text second." Actually I tried this before, the problem I met is to draw the background picture I need capture the image underneath first. I tried using "opacity=0" first then capture the image covered by the container form, but this way made flashing when I move the text around the screen. Is there any other way I can capture the image underneath?
