Creating a Transparent Editbox with No Redraw Problems

Environment: Tested Platforms: Windows 98, Windows 2000, Windows NT

I have written this article to make an edit box transparent. It is very easy to make it transparent when there isn't a bitmap image in the dialog background. But, if you have a bitmap in your dialog background and you make editbox transparent, it will become transparent but will not be redrawn properly.

I have found many programmers suffering with this problem, including me, until I wrote this article. The problem was that making an edit box transparent is very easy in a common case, but whenever you use a bitmap background, it will become a little hard to do. The main problem is that the contents of the edit box will not be redrawn properly.

Here, with this cool code, I have solved this problem. I hope it will be helpful to someone.

About the Author

Hi! Guys,
I am not a well experienced programmer but always try to do my best. So, that's why I wrote this useful article. I am working in a company as senior programmer. We develop software and hardware related to video mixing and photography. My desire is to do a lot in the graphics and image processing fields (using VC++). This is my beginning, so maybe you will not be comfortable with my code. But, your appreciation will become an inspiration for me.

      No transparent effect. (At least on my local test.)
