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.

.net - Unchecked Integer Addition In .Net?

Mar 8, 2010

I 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.

Sockets In .NET Logout Button Addition?

Dec 4, 2011

I have a problem with the code I will be posting down below, when I use the logout button & then I proceed to re-join & the server gets taken down the client crashes/closes, debug mode shows errors in general as the debug session closes out but it doesn't go to any lines of code or anything for me to find where the problem is happening at.

Now I know this isn't a server issue for sure, no bugs show up in the servers coding program at all & it shouldn't take the servers help for a client to disconnect properly between my app being closed & them using the logout button. It only bugs when the server goes down & only after having used the logout button since you've opened the application..

A first chance exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll

OleDbCommand Named Parameters And Order Of Addition?

Apr 8, 2012

I have an ACE OleDb connection to an accdb file that�s working well but I�m mystified by something I recently discovered when using named parameters. Order of adding of parameters overrides the parameter names. I see in the MSDN that is states when in "Text" mode named parameters is not supported. My testing has proven this to be the case. The example below puts "Value 2 in Field1 and "Value 1" in Field2. In fact I could change @value2 to @blahblah and it works.

Dim command As New OleDb.OleDbCommand("INSERT INTO Results(Field1,Field2) Values(@value1,@value2)", con)
command.Parameters.AddWithValue("@value2, "Value 2")
command.Parameters.AddWithValue("@value1", "Value 1")

what is text mode and how do I change it and what other types are there? According to John McIlhinney�s earlier explanation things like date variables are added in a binary fashion including support for DBNull. So this is not "Text" so how am I sending binary data to a Db in Text mode? I�m just not getting why it supports names when it ignores them. Is it simply the case that there is no way to add parameters out of order in my case?If adding out of order is impossible should my command use some other syntax? I see other syntax that just uses question marks in the command dim for the Values section. EG "Values(?,?)".

Is there a way of adding parameters without names?In general I�d love to hear someone to explain this so I can understand the inner workings here a little better and have a little more confidence in what I�m doing here. I can fix my code to work but I feel like an idiot using parameter names that are ignored. I just know I�m doing something wrong even if it works.

So if I put in 3 (points) the counter will count down 9 minutes. If it is possible I want a counter at the bottom every 3 minutes the value of the 000 at the bottom of the image multiply by 1 (+1 for every 3 mins timer1 runs).

Use .next (random Numbers) To Randomly Select Something From A List Of Numbers But It Can't Repeat The Number?

Aug 16, 2009

So how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:

dim num as integer
dim r as new random
num = r.next(1,5)
if num = 1 then
elseif num = 2 then
etc.

That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open. It brought me inside of the folder so I tried to open the game but there is no form1 there. It says the games name then .exe in the explorer-like thing in the top right?Also, how would I have a value or something in a label and access it from a button.

Example:This is in a label.

Dim number as Integer
number = 0

Then in the button do

Label.number = 0

How would I do something like that? I want to use that a lot as I did in a different language.

Box - Conversion Error - User Enters 6 Numbers In 6 Different Text Boxes - Displays The Larger Of Those 6 Numbers

Oct 4, 2011

I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.

Here is my code Example

CODE:

This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.

CODE:

Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.

CODE:

And do this with variable number 2, 3, 4, 5.

I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.

Program To Randomly Select Numbers For A Bingo Caller - Prevent Reversed Numbers Being Selected

Mar 6, 2011

I have just about completed a .NET project to write a program to randomly select numbers for a Bingo caller. Over the last month or so Ive learned a lot about .NET but heres something that I consider to be odd and maybe one of you guys can offer an opinion.

One of the features of calling Bingo in a small local club is that callers often use little sayings to accompany certain numbers, I expect youve all heard of (say) All the sixes, clickety click for 66 or 5 and 9 the Brighton line for 59 etc. My little program gives an option to incorporate these with a prompt for the caller that can be edited outside of the program. One of these conventional sayings is used when a number is reversed 12 followed by 21 or 45 followed by 54 for example, when the caller might call (say) 1 and 2, one dozen, number 12 And the other way round 2 and 1, twenty one.

So, I programmed in a bit of code to detect this and to over-ride whatever might otherwise have been the quote with And the other way round and set about testing it. Ive been through literally dozens of full 90 calls watching for the occurrence of a reversed number, spent a few hours doing it, and not once has it occurred which is to say the least, unusual.

So, Im wondering about the Rand Function, could it be that it isnt possible for a reversed number to be selected? Just so you know, I randomly pre-select the order of all 90 numbers, I fill each of the 90 elements of an array with a random number first checking that the number selected hasnt already been stored, if it has, I just get the next random number (and check that too of course), but I cant see how that could prevent reversed numbers being selected, especially in light of the fact that frequently it's not the 'next' number that's used.
