Understanding C#: Calculator Demo -- Part 8

http://understanding-c-sharp.blogspot.com/2010/01/calculator-demo-part-8.html

Calculator Demo - Part 8. The last thing I wanted to do was complete the calculator's memory. I saved it for last because I thought it would be very simple after finishing everything else. [Unfortunatley, I lied. The memory won't be the last thing to do. I forgot about the menu, but that should be even easier.] I noticed that the original code used a class called "PaperTrail" which is the last class defined in. Static MyTextBox PaperBox; . PaperBox = new MyTextBox(); Grid.SetRow(PaperBox, 1); Gri...But s...

Understanding C#: Calculator Demo -- Part 7

http://understanding-c-sharp.blogspot.com/2009/12/calculator-demo-part-7.html

Calculator Demo - Part 7. I discovered last time. That every operation button invokes the "OperBtn Click" event handler on click which calls the "ProcessOperation" method with the appropriate argument. I want to briefly touch upon each operation in the switch statement of both the "ProcessOperation" and "Calc" methods. Comments by original programmer. Case BMinus: if (EraseDisplay) / stil wait for a digit. { / stil wait for a digit. LastOper = Operation.Subtract; break; } CalcResults(); LastO...If a nume...

Understanding C#: Calculator Demo -- Part 6

http://understanding-c-sharp.blogspot.com/2009/12/calculator-demo-part-6.html

Calculator Demo - Part 6. For the sake of organization and time, I have completed the animations as promised. And I added all the other buttons to the grid. However, I only fully implemented the " /-" operation because I thought it best to visit each operation in the next part. Button Name=BPM Click=OperBtn Click Background=Darkgray Style={StaticResource DigitBtn} Grid.Column=6 Grid.Row=5 /- /Button. This is exactly as the buttons I looked at previously. Except with a different event handler:. Private vo...

Understanding C#: Alarm Clock Sample — Part 5

http://understanding-c-sharp.blogspot.com/2009/12/alarm-clock-sample-part-5.html

Alarm Clock Sample — Part 5. Firstly, every C# program must have a Main() method as an entry point. I added one to a new. Without the "partial" modifier for the class definition) and tried to compile. It wouldn't. For some reason it was complaining about missing references but I put in the correct "using" statements and even tried copying and pasting code that was supposed to work from both Microsoft and Hello WPF (without XAML). Second, I created. Xmlns="http:/ schemas.microsoft.com/winfx/2006/x...ThisN...

Understanding C#: Alarm Clock Sample -- Part 6

http://understanding-c-sharp.blogspot.com/2009/12/alarm-clock-sample-part-6.html

Alarm Clock Sample - Part 6. The most annoying part of losing the XAML was making the animations work. Looking back, it seems pretty simple but getting there led me to a lot of frustration. Every framework element has a resources property. But that page doesn't get into detail about using the resource property without XAML. I had to figure it out from other code. After. You come across the Storyboard Class. The tutorial Particle Effects in WPF. Anyway, here's the play-by-play:. Setting up the Storyboard.

Understanding C#: Calculator Demo -- Part 3

http://understanding-c-sharp.blogspot.com/2009/12/calculator-demo-part-3.html

Calculator Demo - Part 3. I have quite a lot going on now so I haven't been working on this much but I did get around to implementing the basic window for the Calculator. I did it in almost exactly the same way as the Alarm Clock Sample. I created a file. And put in a Main() method, added a startup event handler, and then copied the rest of the file from the original version like so:. Then, I created a file. To, at this point, write the corresponding C# code for the XAML:. Void InitializeThis() { this&#4...

Understanding C#: Calculator Demo — Part 5

http://understanding-c-sharp.blogspot.com/2009/12/it-took-so-much-effort-to-style-buttons.html

Calculator Demo — Part 5. It took so much effort to style the buttons that I'm not going to do the animations until next time. Instead of playing around with the animations like I said I would. I just made sure pressing the buttons would put the respective value into the display area. I had to do a lot of research to translate the XAML for this part into C# so I will follow the same structure that I tried in Alarm Clock Sample — Part 6. This time using the. Defining the button style. LengthConverter lc =...

Understanding C#: Calculator Demo -- Part 9

http://understanding-c-sharp.blogspot.com/2010/01/calculator-demo-part-9.html

Calculator Demo - Part 9. Getting the memory function. To work was very similar to setting up the buttons so I didn't need to look up anything new. I had never seen menus for .NET yet so I did need to look up a couple things. Overall, however, it was extremely simple and didn't take much time at all. As one would expect, rendering menus is very repetitive. I will only detail the "View" menu since that required a "checkable" menu item which makes it more interesting. The menu bar is set up first and is de...
