Edit
Many times we spend hours and hours trying to solve a problem. When we finally figure it out, we want to share it to keep others from suffering the same way!

That's why we have this "Tips and Tricks" thread. Post your solutions and tricks that you think will help someone down the road here.

If the tip is complex or long, you might want to consider making an article out of it and posting it in the Insights forum.

Looking forward to all the helpful tips!

Frinny's Tip O' The Week
Many of us find our way to Bytes.com seeking help while we're facing a programming problem. Sometimes we just need a pointer to get us going in the right direction.

I've started this thread to provide tips and "how-tos" on common problems that everyone faces. Some of these posts will be provided by me (Frinny) but other's will be selected according to how important and informative the posts are.

I hope you'll find something useful here!

Ben's Tip o' the day:

Always save your work before you go home at night and don't expect that your computer won't have rebooted itself by the time you come into work the next morning!

Well, I've recently discovered how to hide the caret (cursor) in a textbox.

Expand|Select|Wrap|Line Numbers

 [DllImport("user32")]

private static extern bool HideCaret(IntPtr hWnd);

Then, write an event handler for the "Enter" event for the textbox, and use the handle of the textbox. Like this:

Expand|Select|Wrap|Line Numbers

 private void tbOutput_Enter(object sender, EventArgs e)

{

    HideCaret(tbOutput.Handle);

}

Vertical progress bar
------------------------------------------------------------
Derive your class as shown below

Expand|Select|Wrap|Line Numbers

 
class VertProgress : ProgressBar

{

      override CreateParams CreateParams

      {

           get

           {

                 CreateParams crParam = base.CreateParams;

                 crParam.Style |= 0x04;

                 return crParam; 

           }

       }

}

Once you build your application, in the toolbar you will see VertProgress. Drag and drop it in the windows form. Strech it vertically.
