This program simply shuts down, restarts or logs-off the Windows after a time period chosen by user. May be run with parameters (Automatic mode). It is written in DevCPP.
This is also my first Win32 program. I studied Win32 programming by writing this program.

My first problem is... Edit controls doesn't look like normal edit controls. I mean they look flat. I want to make a 3D appearance.

The second, I couldn't add resource files to the .exe file. Program uses icons from external files. I know it is done by using .rc files, but HOW?

A attached the entire project. You may download and have look.

You need to give the property of the EDIT control to have a border. You are using dwEditStyle Add to the styles WS_BORDER.

You dont need to embed the rc in the exe but the compiler should do this when creating the exe. The rc should always link to the external file.

Re: A Sample Code
 
1) With WS_BORDER it really looks bad. There just appears a black rectangle enclosing the Edit control.
2) I said I knew that compiler does that linking operation. But what I don't know is how to prepare an rc file and add it to the project. Whatever, forget about it... Just an answer for (1) is enough for me.

You need to make the Apperance as 3D its by default as Flat
