This is a calculator that is similar to the XP PowerToy calculator, but with additional features.

  • Conversion mode: Easily convert between different types of units, say inches to centimeters or teaspoons to tablespoons.
  • Expressions mode: Enter an arbitrary number of expressions and then a formula at the bottom that uses the expressions to produce output. This makes it easy to change the values of the inputs without having to rewrite the whole formula. For example (this is the pythagorean theorum): 
   Expr1=    1
   Expr2=    2
   Formula:  Sqrt(Expr1^2 + Expr2^2)
  • The entry can accept variable assignments and use them in the calculation. Example: a=1; b=2; a + b + a^2 + b^2 outputs 8
  • When entering a calculation, the immediate result is displayed at the bottom. When you hit enter, the entry and the result are added to the history, so you don't lose previous work.
  • Results can be in decimals, hexadecimals, or binary. Numbers can also be entered in these using prefixes of "0x" for hex or "0b" for binary.
  • Results are formatted for easy reading, by grouping digits. For example: 10000+1/128 outputs 10,000. 007 812 5

Detecting MouseEnter and MouseLeave in a control that has lots of children controls (.Net)

Submitted by drew on

Seems like I have been through this before. What I want to do is hide and show something, depending on whether the mouse is inside of a certain area. For instance, I have a container of some sort with lots of controls on it. When the mouse is anywhere inside of the container, I want a link to be visible. I can't simply use the MouseEnter/MouseLeave events on the container, because MouseLeave is triggered when the mouse enters a child control and the MouseEventArgs don't say anything about what control is being entered.

Say Goodbye to Windows 8's Start Screen

Submitted by drew on

 

All of the people I've talked to who don't like Windows 8, don't like it because of the new start screen. You know, the tiled "apps" screen. A.K.A. "Metro" screen.

Maybe that sort of thing makes sense on a touchscreen device. Not on a desktop computer or standard laptop.

This free software brings back your start menu, like in Windows 7: ClassicShell. If you set it to start in desktop mode, you can say goodbye to the start screen! Here's how.
