Calculator - 2 Textboxes Where The 2 Numbers (or Values Go For Addition And Subtraction)
Aug 12, 2011I 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.

Jun 27, 2011i have the following piece of code: txtGrandTotal.Text = Val(textbox1.Text) + Val(textbox2.Text) + Val(textbox3.Text) If the numbers entered into textboxes1,2 and 3 are positive integers it all works fine, but if for example the following happens i get unexpected results textbox1 has the number 3, textbox2 has -1 and textbox3 has 6. I expect the result to be 8 (3-1=2 + 6) = 8 Instead I get 14. I understand the concept of precedent but how do I set it if I don't know if the number entered into textbox is positive or negative?
View 5 RepliesCan't Get The Right Numbers Inside The Textboxes
Dec 29, 2008[URL] I'm trying to do an exercise on that website but it doesn't show the answers to the exercises..
I've gotten everything to work except one thing. I can't get the right numbers inside the textboxes! I've been sitting here for like an hour trying to use a case statement.. it didn't work for me so I tried to use if then statements and I still couldn't get it to work!
Here's my code for that part:
Ignore the second if I was desperate xD
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click

And for the Case statements, if I wanted to use it for a range of numbers, do I write "Case 1 To 10" and that's numbers between 1 and 10? Is that right?

Combinations Of Multiset Numbers In 5 Column Textboxes (of Range 1-90)?
Jun 5, 2011I have 5 columns of 11 textboxes each on my form the textboxes are generated with this code
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'column 1 textboxes
[Code].....
i need a code to generate all the possible combination of the numbers a user types into the textboxes i have two images (Panel3: the textboxes where added during design time) image2: the textboex were added using the code i gave about
generate all the possible combinations of numbers typed into the textboxes (Example see panel3.jpg image),
The user will type in the desired unique numbers into the textboxes without repetition (Please see the image i did not repeat any number, so can the code detect when a number have been typed twice?) Else when running the program i will be carefull not typing two numbers twice, but its adviceable to detect when a number is typed more than once.
Then the amount of unique number the user will type or supply to the desired textboxes does not matter here and as you can see in the image the amount of numbers in each column is not the same ie it may or may not be same amount (but number must be unique. Please try and see if it can be done to prompt user to enter the amount of numbers to supply in each column)
Then After supplying the numbers just like the one in Image, The button Click will generate all the Possible Combinations of the all the numbers typed into the textboxes in the columns.. Then After generating the combinations in the Listbox, the next Button will be able to delete them from the Universal 90c5 just like the former.

.net - Unchecked Integer Addition In .Net?
Mar 8, 2010I have a project where I want to have checked arithmetic by default, except for one performance sensitive spot. Unfortunately, VB.Net doesn't have an 'unchecked' block.Ideally the framework would have some sort of integer type with explicitly unchecked arithmetic, but I didn't find anything like that. I did find that expression trees have binary expressions for unchecked operations, but the delegate overhead cancels out the unchecked advantage (and then some).
Currently I'm converting the inputs to UInt64/Int64 before doing the arithmetic, then converting back (with a bitwise And to ensure in-range). It's about 50% slower than unchecked arithmetic (according to profiling).
Moving the arithmetic-sensitive part to a project with unchecked arithmetic might work, but it seems like overkill to give it an assembly all to itself.
