Calculator - 2 Textboxes Where The 2 Numbers (or Values Go For Addition And Subtraction)

Aug 12, 2011

I have made my calculator and it has 2 textboxes where the 2 numbers (or values go for addition and subtraction) are input and a label where the answer appears. There is other things on the page such as quit, clear etc thats all done but i have one query. I noticed while testing a problem occurs when only one number or value is put into a textbox and a command is hit. For example. one textbox (txtnumber1) has one number in it then i hit multiply and it says the error of course because its not programmed to deal with this (or divide by 0 of course) so i was wondering how i could make so when this happens a MsgBox appears saying a value must be in both boxes or when divded by zero is says something similar.

The line of code:

Private Sub blah blah blah...

If txtnumber1.Text = False Then MsgBox("Please Input Valid Value")

End Sub

I however have not been able to make it work.

Show An Explanation And For The Addition And Subtraction - Show It On A Number Line

Mar 7, 2010

I'm writing a program for my algebra students to practice integers.Stuff like....

3-6
-4 + (-5)
3(-4)
-15 � 3
etc.

I want to show an explanation and for the addition and subtraction, I want to show it on a number line. For example, if the problem is 3 - 7, the number line should show and arrow to that goes right to 3, and then left 7 units (starting from 3). Then the student can see that the answer is -4.I could probably do this with some string manipulation, but what would be the easiest way to do it in a picture format? Maybe a bitmap.

Extend Program So It Has Subtraction As Well?

Oct 15, 2009

Remember this from before?

Quote:

Since you are repeating same operation three times it is best to make a function for it.

CODE:

labels 1-6 are randomly generated numbers, text boxes 1-3 are the input boxes and the code above shows how if the answer in the textbox equals the labels added together, you win. This code works -

I have created labels 7-12 now, and textboxes 4-6. How can I extend this program so it has subtraction as well?

If this problem definition isn't detailed enough, let me know and I'll add more detail to this description.

Boolean Subtraction Of Two Meshes With Direct3D

Jun 20, 2009

i'm working on a simple 3D CAD to create complex 3D objects. This application uses:

1. Direct3D to render the objects
2.The methods contained in the Mesh class (such as Mesh.Box(...)) to create them
3.The Matrix class to apply some basic transformations (such as Translation or Rotation)

My issue is to do a boolean subtraction of a Mesh to another one to create a more complex Mesh, for example a Mesh with holes.

Division By Zero For Oledbconnection?

Feb 24, 2011

I am using oledbconnection object with access database engine 64 bit to get data from Excel file. While using sqlconnection object if sql string has these statements "SET ARITHABORT OFF;SET ANSI_WARNINGS OFF;" , then division by zero exception doesn't cause any problem. But while using oledbconnection these statements cause error. My code samples are below:

Dim PbpConn As OleDbConnection = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=C:BuzBeatDataPBPData.xls" & ";" & _

[Code]....

When SUM(pbA) has value "0" then it causes error and can't get data. is there a way to close the warnings and division by zero exceptions?

Approximating The Result Of A Division?

Nov 16, 2010

I've got a problem approximating the result of a division that should give a sharp result:

I use this code:

pListPrice *= 100 / (100 + VATPercentage)

where VATPercentage = 20D is declared as Decimal type. pListPrice = 25.2D is declared Decimal too.

The result should be: 21.00 sharp!

Instead I get 20.99999999999999999999D

Bug On Rounding On Division And MOD Of Integers?

Feb 11, 2012

I have a group of 25 labels named Label1, Label2, Label3, ... Label25 in a square of 5 per row, 5 per column and I wanted to assign the backcolor to all of them on a loop and assign a value of "True" or "False" to a matrix of 25 boolean values representing them.

But I was getting errors on the pattern created.

My approach was to use a substring containing a number copied from the label names:

Num = Val(sender.name.substring(5))

And the subindexes of the matrix:

p = (Num - 1) / 5
q = (Num - 1) Mod 5

The values for the lower corner of the matrix were rouded to 5 instead of being 4. Instead of (4,0) ,(4,1), (4,2), (4,3) (4,4) I was getting (5,0),(5,1)...(5,5)

So I solved the problem by creating two single variables "A" and "B", doing the divission and MOD operations on them, finding the floor of them and then converting to integer:

Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _
Label1.Click, Label2.Click, Label3.Click, Label4.Click, Label5.Click, _

Using Modulous And Division In An Exercise

Mar 6, 2005

This exercise says :"Write a program that inputs one number consisting of five digits from the user, separates the number into its individual digits and prints the digits separated from one another by three spaces each. For example, if the user types the number 42339, the program should print
4 2 3 3 9 Use the command window for input and output. [Hint: This exercise is possible with the techniques discussed in this chapter. You will need to use both division and modulous operations go "pick off" each digit.]"

Here is what I have learned in Chapter 3:

�If/Then Statements
�Console.Write()
�Console.WriteLine()

[Code]....

This exercise I have yet to start, and don't think I will be able to do much, because I have no clue how to "Pick off" the numbers using division and modulous operators. I know what the mod operator does, but I do not know how to use it and division to do what this exercise is asking me to do.
